Bayhorse Silver: Riding the VTEM Rocket

Not quite a rocket, yet, but a year ago Bayhorse Silver (BHS.V) was very close to the end. While it had a silver mine, a mill and an ore sorter, it did not have a final permit which would allow it to actually operate its mine. In some jurisdictions, this would not have been a show stopper and the permit would arrive in short order. But the Bayhorse mine is in Oregon, a state where mining is politically unwelcome. The permit was going to take a while.

BHS CEO Graeme O’Neill scrambled to raise money, put a lot of his own money into a couple of small private placements and managed to arrange a lease for the ore sorter. It was enough to keep the company going, barely. BHS shares fell to $0.015

Then, in October 2023, Hercules Silver (BIG.V) announced that it had drilled into what it described as a “blind copper porphyry” at its property at Cuddy Mountain, 44 kilometres down the Snake River on the Idaho side. BIG went from less than $0.20 to a high of over $1.60 in a matter of weeks. It did a deal with Barrick and now has 23 million dollars to drill out its discovery.

Here is the interesting thing, the Hercules discovery is at what geos refer to as a “suture” between the Izee terrane and the Olds Ferry terrane. Its silver is found in a rhyolite structure. The blind copper porphyry looks to have been part of the geological events which created the silver in the rhyolite.

People began to talk about “closeology”. Bayhorse finds its silver in a rhyolite structure. The Bayhorse mine is at a suture of the Izee and Olds Ferry terranes. The argument from similarity can be and was made and O’Neill raised a little over 1 million dollars in a private placement.

The biggest problem Bayhorse has faced over the years is a lack of money. The million dollar private placement, powered by the Hercules discovery, solved that in the short term. For the first time in its existence, Bayhorse had the money to explore and a reason to spend that money.

The Bayhorse value proposition has always been the re-opening of a successful, past-producing, silver mine with high-grade silver, interesting copper and gold credits and a CEO who understood logistics. O’Neill would certainly look at, and sometimes option, greenfields exploration plays, that was never the company’s focus. O’Neill knew that if he could jump through the permitting hoops, the Bayhorse mine had years of unmined, high grade, silver to extract, concentrate and sell. It still does.

Hercules provided the hint. Was the geology at its Izee/Olds Ferry terrane similar to the geology surrounding Bayhorse? O’Neill had the money to start finding out.

VTEM is a helicopter flown magnetic and resistivity survey which can locate “anomalies” down several hundred meters. Bayhorse had never had the money or a reason to fly a VTEM, now it did and in early January of this year it flew both sides of the Snake River.

While BHS may have been inspired by BIG’s success downriver, its own geological team had scouted out what it believed was a substantial rhyolite structure on the Idaho side which the geos postulated was an extension of the Bayhorse mine rhyolite. That same geo team had long speculated that the Bayhorse mine itself was potentially “over” an epithermal gold/copper intrusion. A structure which would line up with the geological theory being tested at the Hercules property.

The results of the Bayhorse VTEM were outstanding. On the Oregon side, there was an area of low resistivity right under the western end of the Bayhorse mine workings. On the Idaho side, there were three areas of low resistivity and a magnetic high right where the Bayhorse geos expected the rhyolite extension to be. And that high was, in fact, higher than the high at the Bayhorse mine itself.

Here is the map of the magnetic signatures:

Here is the map of the resistivity signatures:

Bayhorse Silver, BHS.V, Silver, Copper, gold, Oregon, Idaho

 

 

All of a sudden Bayhorse Silver went from a company with a plan to re-open a mine to a company which had four resistivity targets and a huge magnetic anomaly to explore.

Bayhorse has been lucky to have senior geologists advising O’Neill as he drove towards recommissioning the Bayhorse mine. That luck was extended when Spokane-based explorationist Mark Abrams was initially signed on as a consultant to finish off the final permitting process and then as a Director.

Abrams is very much the right man at the right time. He is a fully licensed geologist in both Oregon and Idaho and has conducted exploration programs for majors like Placer Dome and Agnico Eagle. He knows how to run a serious exploration program.

I was fortunate to speak to Abrams a few days ago. He was optimistic about Bayhorse’s prospects. He was also very much an explorationist. “You need boots on the ground,” he told me. “We need to be prospecting. Looking at the sediments in the catchment areas. Get into the drainages.”

“You’re putting dots on the map,” said Abrams.

Which is the great paradox O’Neill and his team are faced with. They can see the high magnetics and the low resistivity. They have targets in general. But in the real world of exploration, this is the earliest possible stage.

Right now, BHS can, and should, stick to its knitting and drill the Big Dog, the footwall and the low resistivity at the Bayhorse mine which is exactly what it is doing. It will take a while to get the surface drilling permits in Idaho. Time which can be spent profitably increasing the staked land, perhaps doing an IP survey on one of the blobs, collecting samples and surface “shows” and figuring out where best to begin drilling what may be a significant copper porphyry.

For Bayhorse shareholders the BIG news and the VTEM results have started an increase in value. From $0.015 to .08 in a couple of months. However, that is likely just the beginning. By drilling underground BHS is creating a hard news stream likely to continue well into Fall.  The Idaho targets are a largely unexpected bonus.

Bayhorse Silver Substantially Increasing Idaho Mineral Tenements

ayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the “Company” or “Bayhorse”) announces that preliminary results of the recently completed Geotech Ltd. helicopter-borne VTEM and Horizontal Magnetic Gradiometer Geophysical Survey over its Bayhorse Silver Mine Property, Oregon and Idaho, USA have been received.

On the basis of the preliminary results, the Company is substantially increasing the number of its claims and exploration area in Idaho to 2,460 acres.

A comprehensive review of the final VTEM results when received will be undertaken by the Company’s geophysical and geological consultants. The Company expects to receive the final VTEM report within the next two weeks.

The VTEM survey over the entire Bayhorse property in both Idaho and Oregon was to determine whether a long-postulated feeder anomaly is present at the Bayhorse Mine that could indicate the presence of either more high-grade silver mineralization or a porphyry copper deposit.

The Bayhorse and Hercules Silver property, 44 Km to the northeast of the Bayhorse Mine, have similar geological settings and copper/silver mineralization, including significant copper, antimony, and zinc credits.

The Company’s senior geological consultants believe that it is also possible that the silver-rich Bayhorse epithermal mineralization may also be underlain by a gold-rich zone, as suggested by Buchanan’s 1981 model.

This News Release has been prepared on behalf of the Bayhorse Silver Inc. Board of Directors, which accepts full responsibility for its content. Mark Abrams, AIPG Certified Professional Geologist, a Qualified Person and Director of the Company has prepared, supervised the preparation of, and approved the technical content of this press release.

Eloro: Bulk Sampling for Bulk Mining…and a New, Huge, Target

The metallurgical drill holes used at Iska Iska are larger diameter than the regular diamond drill exploration holes. For Eloro (ELO.T) and its CEO, Tom Larsen, this makes all the difference. “The more the better,” said Larsen in a telephone interview. “The Iska Iska minerals are mainly disseminated in stockworks and veinlets. A bulk sample is much more representative of the grades you will encounter when you mine the deposit.”

In the original MRE starter pit section, based on assays of narrow, exploration holes, the silver head grade was estimated at 24 grams per ton silver. In the press release January 24, 2024 which covered the metallurgical holes and two twinned diamond drill holes and the bulk sample taken from that material, ELO reported a head grade of 91 grams per ton silver in the bulk sample in comparison to the 31 gpt from the twinned diamond drill holes.

“We recovered 7-8 tons of material from the met holes,” said Larsen. “We bulk sampled 6 tons of that material. Bulk sampling is the proper way to get a more accurate representation of the deposit. It’s more expensive but a bulk sample is more realistic because we will be bulk mining.”

“The grades can significantly increase with bulk mining,” said Larsen. “We are looking at bulk mining 30-50 thousand tons per day in the starter pit.”

Once you understand the idea of “bulk mining” the rest of this lengthy press release makes a lot more sense. Based on the head grade results of the bulk sample, introducing a pre-concentration stage into the flow sheet can give ELO a huge economic advantage.

“XRT ore sorting is a game changer,” said Larsen. “A lot of people misunderstand ore sorting. They see it as a gimmick to upgrade low grade material. It isn’t. It’s a way to create a high-grade pre-concentrate by separating the higher grade material and stockpiling the less enriched material.”

The press release outlined the success TOMRA had using its XRT ore sorting technology for the coarser sized fractions in the pre-concentration stage and using the well understood Dense Media Separation treatment of the finer fractions so as to pull on the strengths of both technologies.

“All of this will be going into a revised Mineral Resource Estimate,” said Larsen. “We are going to take our time, use proper, conservative, representation and make sure that nothing is under-reported.”

“The met holes plus the infill drilling will enhance the grade and expand the tonnage in the starter pit,” said Larsen. “We’re starting off with the 135 million tons in the first MRE. Our infill drilling will add at least 50 million tons of polymetallic metal value. There is a real chance we’ll report 200 million plus, once everything has been modelled.”

“We are also hoping for 50 million tons of .2-.3% tin,” said Larsen. “This should be included in the updated MRE but it will be in time for the PEA.”

Until the PEA, Larsen cannot discuss the Net Present Value of the project at Iska Iska. But he did allow that the previous cost per ton estimate of just over $9.00 was still seen as correct. “Now that we know the material is amenable to ore sorting we’ll have to factor in the cost of sorting, but that looks to be $3 to $5.00 a ton.”

Larsen can’t run the numbers, yet. However, if you take a potential 200 million tons of 50 gram per ton silver average using a $0.70 per gram price, the silver alone is worth $35.00 a ton. Assuming mining costs at the Santa Barbara starter pit site are US$14 a ton and you deduct the zinc and lead credits to offset the metallurgical recoveries, input costs of processing, transportation and smelter fees(NSR), you are left with an approximate $50 net value per ton of material. Times 200 million tons in the proposed starter pit: 10 billion dollars worth of rock.

When I spoke with Larsen last week, he suggested holding this piece until last Monday. Which usually means news and this was no exception.

IP at Iska Iska

On January 29, 2024, Eloro released the results of an expanded induced polarization/resistivity (IP/Res) survey at Iska Iska. Dr. Bill Pearson, Eloro’s VP Exploration is quoted in the release,

“The new chargeability anomaly, extending southeastward from the open pit that defines the MRE, adds at least an additional 600m of potential strike length to the major mineralized structural corridor that is up to 800m wide for an overall strike length of at least 2km. This new target area has not been drilled. In addition, the chargeability anomaly southeast of the pit is very strong, suggesting that it is a prime target for outlining additional higher-grade polymetallic mineralization.”

At first reading, the IP results suggest a very large target outside the bounds of the current conceptual pit shell. It has not been drilled however, Eloro’s previous drilling has been into targets which exhibited much the same IP/Resistivity profiles. A fact made clear in this figure:

Adding this target to an already enormous project offers a huge opportunity while creating large challenges for what is essentially a small exploration company. Drilling to confirm the anomaly and the mineralization and grades it contains is a very big project in itself.

Eloro’s current share price rose a bit on the IP news going to $1.90 and giving the company a market cap of 145 million Canadian dollars. It has fallen back a bit to a current $1.65 for a market cap of 123 million. The disconnect between the asset value and the current market cap is enormous and will become recognized.

Bulk Tonnage Metallurgical Tests Return Significantly Higher Silver Head Grade of 91 g Ag/t Compared with the 31 g Ag/t Average Grade from the Original Twinned Holes in the Polymetallic Domain at Iska Iska, Potosi Department, Southwestern Bolivia

Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce the final results of its bulk metallurgical test program on the Iska Iska silver-tin polymetallic project in the Potosi Department of southwestern Bolivia.

Tom Larsen, CEO of Eloro commented: “The substantive difference in average silver grade in the bulk sample compared to the twinned holes strongly suggests that the silver grade in the two original twinned holes is likely significantly underreported due to the much smaller sample size. The recently released results from the definition drill program in the same general area within the initial MRE (see Eloro press releases dated December 18, 2023 and January 11, 2024) which yielded a number of higher-grade Ag intersections, also reflected in the improved silver grade equivalent values, further supports this underreported silver grade conclusion. These results highlight the fact that tighter spaced drilling is required to have a more representative sampling of high-grade areas in the Iska Iska deposit to obtain a more accurate estimate of the likely true overall grade.”

Mr. Larsen continued: “While the initial test program focussed on the higher-grade part of the Polymetallic Domain as this is where the bulk of the current mineral resource is, further testwork is planned on the Tin Domain which is very under-drilled. The recent definition drilling reported significant Sn results and it is expected that additional definition drilling will expand and upgrade the tin resource so that it can potentially be included in the preliminary economic assessment (“PEA”) in progress.”

Mike Hallewell, newly appointed as Eloro’s Senior VP Engineering Projects/Metallurgy said: “The results indicate that 91.9% of the Silver and Lead, and 76.0% of the zinc can be pre-concentrated into a relatively high-grade mill feed product constituting only 46.6% of the original tonnage. The upgraded product results in higher flotation plant feed grades that will assist flotation stage recoveries. Both XRT “Ore Sorting” and DMS are well known, low risk separation technologies that provide Eloro with a great opportunity to significantly reduce operating and capital costs, reduce the mine cut-off grade and enhance flotation stage recoveries. The small differences in the -60mm+25 mm and -25mm+9.5 mm size fractions suggests that the top size could be increased above 60 mm. This would increase the percentage of Run-of-Mine (“ROM”) secondary crushed material that would report for pre-concentration, which would enhance the overall benefit of pre-concentration. The much higher Ag grades of 91 g Ag/t in the bulk metallurgical sample as compared to the twinned holes grade of 31g Ag/t is very encouraging. This along with the very high test recoveries for Ag, will have a major positive effect on potential project economics.”

METALLURGICAL TEST PROGRAM

As previously reported (see Eloro press release dated November 1, 2023), three metallurgical drill holes totalling 940 m were completed at the Iska Iska project. Two holes targeted the higher-grade Polymetallic (Ag-Pb-Zn) Domain while the third hole sampled the higher-grade Tin Polymetallic (Sn-Ag-Pb) Domain. These metallurgical holes were drilled using PQ core (~85mm Ø) and were designed to twin previous HQ core drill holes which contained representative mineralization with values for the predominant higher grade Polymetallic (Ag-Zn-Pb) outlined in Table 1. As shown in Figure 1, these metallurgical holes were targeted in the potential higher-grade starter pit area at Santa Barbara which contains an estimated mineral resource at a cutoff of NSR US$25/t of 132 million tonnes at 24.3 g Ag/t, 1.11% Zn and 0.50% Pb (72.06 g Ag eq/t) (see Eloro press release dated October 17, 2023). The drill core selected for testing from these holes, which totaled 7.9 tonnes from 519 m of drill core, was shipped to Wardell Armstrong International (“WAI”) in Cornwall, England, for crushing to 60mm and sizing into five different size fractions. The -60 mm+9.5 mm crushed and sized product was sent to TOMRA GmbH based in Wedel, Germany, for separate cascade “ore-sorting” tests on -60 mm+25 mm and -25mm+9.5 mm.

The testing program reported in this release focussed on the two PQ drill holes in the Polymetallic Domain which contain the majority of the tonnage and metal, namely MET-DSBU-10 and MET-DSB-30. The sample size tested was 6.3 tonnes from 418m of the overall drill core sent to WAI. Further PQ diamond drilling is planned to obtain a bulk metallurgical sample from the sulphide Tin Domain, in addition to testing MET-DSB-32 which is in the oxide zone of the Tin Domain. The Tin Domain, although it contains an inferred mineral resource of 110 million tonnes grading 0.12% Sn, 14.2 g Ag/t and 0.14% Pb (38.02 g Ag eq/t) (see Eloro press release of October 17, 2023), is very under-drilled especially to the west. The recent definition drilling reported significant Sn results and it is expected that additional definition drilling will expand and upgrade the Sn resource so that it can potentially be included in the PEA in progress.

The -9.5 mm+0.85 mm size fractions were subject to heavy liquid analysis performed on two separate size fractions (-9.5mm+5mm and -5mm+0.85 mm) to identify the amenability of the finer size fractions to Dense Media Separation (“DMS”). The -0.85 mm material and the pre-concentrated products from the “ore sorting” and heavy liquid tests will provide testwork material for further PEA level grinding and flotation metallurgical testwork at WAI. This work builds on previous metallurgical test work using representative Iska Iska samples, as summarized in the Company’s National Instrument 43-101 (“NI 43-101”) Technical Report filed on Sedar+ (see Eloro press release dated October 17, 2023).

These metallurgical drill holes also provided an important comparative bulk sample test of mineralization grade relative to the weighted average grade of the twinned holes.

SUMMARY HIGHLIGHTS

1. Overall Summary Tests

The main focus of this testwork phase has been on the predominant Ag-Pb-Zn Sulphide Domain which accounts for the majority of the mineral resource tonnage and metal values. Table 1 below shows the compelling results from this preliminary study on the full bulk PQ sample representative of the higher grade Polymetallic (Ag-Zn-Pb) Sulphide domain. The results indicate that 91.9% of the silver and lead, and 76.0% of the zinc can be pre-concentrated into a relatively high-grade mill feed product constituting only 46.6% of the original tonnage. The upgraded product results in higher flotation plant feed grades that will assist flotation stage recoveries. While 91.1% of the bulk sample (-60mm+0.85mm) reports to pre-concentration the remaining 8.9% of the material by-passes pre-concentration and can be blended directly with the pre-concentrated feed ahead of grinding.

Table 2 below compares the individual back calculated head assays coming from the PEA preconcentration test work program with the assays from the 1/2 HQ twinned exploration holes. The overall weighted average Ag assay was significantly higher in the bulk PQ metallurgical hole sample at 91 g/t Ag as compared with the two original HQ geological twinned holes at 31 g/t Ag. This substantive difference in average Ag grade strongly suggests that the silver grade in the two original twinned holes is likely to be significantly underreported due to the much smaller sample size. The recently released results from the definition drill program in the same general area (see Eloro press releases dated December 18, 2023, and January 11, 2024) which yielded a number of higher-grade Ag intersections, further supports this conclusion. These results highlight the fact that tighter spaced drilling is required to have a more representative sampling of high-grade areas in the Iska Iska deposit to obtain a more accurate estimate of the likely true overall grade.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 100% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020, Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu over 166m including 446 g Ag/t, 9.03% Pb and 1.16% Sn over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the initial discovery hole DHK-15 which returned 29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu and 0.056%Sn over 257.5m, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined an extensive target zone. On October 17, 2023, Eloro filed the NI 43-101 Technical Report outlining the initial inferred MRE for Iska Iska, prepared by Micon International Limited. The MRE was reported in two domains, the Polymetallic (Ag-Zn-Pb) Domain which is primarily in the east and south of the Santa Barbara deposit and the Tin (Sn-Ag-Pb) Domain which is primarily in the west and north. The Polymetallic Domain is estimated to contain 560Mt at 13.8 g Ag/t, 0.73% Zn & 0.28% Pb at an NSR cutoff of US$9.20 for potential open pit and an NSR cutoff of US$34.40 for potential underground. The majority of the mineral resource is contained in the constraining pit which has a stripping ratio of 1:1.

The Polymetallic Domain contains a higher-grade mineral resource at a NSR cutoff of $US25/t of 132 million tonnes at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t which has a net NSR value of US$34.40/t which is 3.75 the estimated operating cost of US$9.20/t. The Tin Domain which is adjacent the Polymetallic Domain and does not overlap, is estimated to contain a mineral resource of 110Mt at 0.12% Sn, 14.2 g Ag/t and 0.14% Pb but is very under drilled.

The Company has completed a 5,267.7m definition drill program to upgrade and expand the higher-grade mineral resource in the Polymetallic Domain and has commenced a PEA led by Lycopodium.

Eloro Resources Intersects 57.62g Ag/t, 1.26% Zn, 0.94% Pb and 0.12% Sn (139.94g Ag eq/t) over 136.11m in Definition Drilling at the Iska Iska Project, Potosi Department, Southwestern Bolivia

Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce the final assay results for the last six (6) diamond drill holes in its eleven (11) hole 5,267.7m definition drill program on the Iska Iska silver-tin polymetallic project in the Potosi Department of southwestern Bolivia.

Tom Larsen, CEO of Eloro commented: “I am very pleased with the continuation of significantly higher-grade silver equivalent results from the latest definition drilling program, compared to the initial mineral resource estimate (“MRE”) starter pit area model as previously reported (see Eloro press release dated Oct 17, 2023). These new results highlight the potential to upgrade and expand the higher-grade resource in the Santa Barbara starter pit area.”

Larsen continued: “Tin is proving to be an important metal contributor to these upgraded silver equivalent results. This can enhance NSR values and increase tonnage in future MRE studies. As an example, Hole DSB-63 located in the Northeast section of the Santa Barbara starter pit area, recognized more as a Polymetallic (Ag-Zn-Pb) Domain, returned 0.51% tin over a 23.02-meter drill intercept with a total silver equivalent value of 205.57 g/t.

There is more and more evidence of high temperature sulphidation centres being identified as feeders within the open pit area resulting in upgraded tin and silver values. Higher density definition drilling in the initial Santa Barbara open pit envelope is consistently proving up higher grades as drill density is improved.”

Dr. Osvaldo Arce, P.Geo. General Manager of Eloro’s Bolivian subsidiary Minera Tupiza S.R.L. and an expert on Bolivian mineral deposits said: “The definition drilling is confirming a strong high-grade Ag-Sn association, which is common in the southern Bolivian Tin Belt, including in large systems at Cerro Rico de Potosi, Animas-Siete Suyos-Chocaya and Tatasi deposits that occur along NW-SE striking structural corridors, the same geological environment that is present at Iska Iska.”

Dr. Arce continued: “Recent drilling results have outlined upgraded tin and silver values from near surface down to at least 500m in vertical extent, principally in the sulphide zone. Geophysical information and deep drilling indicate that tin-silver mineralization may extend to depths of 1km or more. Tin mineralization in these zones has been remobilized and redeposited throughout the deposit by brecciation in favorable rock types, especially medium grained porphyritic dacite and intrusion breccia which are the most widespread lithologies at Iska Iska. Moreover, tin-polymetallic mineralization can be locally extensive/continuous as occurs in hole DSB-67, where 477m of the 500m drilled averages about 0.1% Sn, with almost no waste material. This high-grade continuous polymetallic mineralization forms commonly subhorizontal vein-parallel banding along north-northwest trending shear zones, indicating multiple episodes of fracture opening and mineral precipitation.”

DEFINITION DRILL PROGRAM

Table 1 below lists significant results for the six drill holes reported. Figure 1 shows locations of all the definition drill holes completed with the holes reported in this release highlighted. Silver equivalent (g Ag/t) has been calculated using 3-year average metal prices and preliminary metallurgical recoveries (see note below Table 1 for more information). Table 2 lists the coordinates of the definition drill holes reported in this release.

The definition diamond drill program focussed on upgrading and expanding the higher-grade Polymetallic (Ag-Zn-Pb) Domain Type inferred mineral resource, which as previously reported (see Eloro press release dated October 17, 2023) contains an inferred mineral resource of 132 million tonnes at 24.3 g Ag/t, 1.11% Zn and 0.50% Pb (72.06 g Ag eq/t) at an NSR cutoff of $US25/t. The net NSR value of this higher-grade resource is US$34.40/t which is 3.75 times the estimated operating cost of US$9.20/t. Several of these holes also tested the adjacent Tin (Sn-Ag-Pb) Domain where high values of silver (Ag) have previously also been obtained in addition to tin (Sn).

Drill hole locations were planned to fill-in major gaps in the block model as well as upgrade and expand the higher-grade zone both along and across strike in the general area of the potential starter pit. As noted by Micon International Limited (“Micon”), authors of the National Instrument 43-101 (“NI 43-101”) Technical Report detailing the initial Iska Iska MRE (see Eloro press release dated October 17, 2023), the highest-grade areas are also the best drilled. As drill density in the deposit is improved, it is expected that grade will increase due to better sample density. Results previously reported (see Eloro press released dated December 18, 2023) and results reported herein confirm that this is likely the case.

Figures 2 and 3 are west-east sections showing the distribution of tin and silver, respectively, incorporating definition drill results along with distribution of mineral resource blocks with an NSR value greater than US$25 per tonne from the Micon mineral resource model. These sections highlight how the definition drill program has expanded both the higher-grade Sn and Ag zones especially to the west where there has been very little previous drilling.

These new data highlight the potential for expanding the mineral resource particularly outlining a significant higher-grade Sn resource to include for consideration in the PEA. As noted in the Eloro press release of November 1, 2023, the PEA was planned to focus solely on the higher-grade Polymetallic (Ag-Zn-Pb) with Sn being a major exploration target. The results of the definition drill program highlight the potential to significantly expand the higher-grade Sn resource to the west of the current potential pit and to incorporate this new potential resource area into consideration for the PEA.

The following is a summary of significant diamond drill results from the six holes:

Hole DSB-66 intersected several long well mineralized intervals as follows:

  • 57.62g Ag/t, 1.26% Zn, 0.94% Pb and 0.12% Sn (139.94g Ag eq/t) over 136.11m from 137.75m to 273.86m including:
    • 136.81g Ag/t, 2.00% Zn, 1.38% Pb and 0.17% Sn (255.19g Ag eq/t) over 34.77m from 187.64m to 222.41m
  • 24.67g Ag/t, 1.08% Zn, 0.83% Pb and 0.08% Sn (94.46g Ag eq/t) over 86.39m from 288.92m to 375.31m including:
    • 69.37g Ag/t, 0.41g Au/t, 1.88% Zn, 3.68% Pb and 0.32% Sn (272.27g Ag eq/t) over 6.08m from 307.15m to 313.23m,
    • 23.59g Ag/t, 2.14% Zn, 1.57% Pb and 0.15% Sn (159.64g Ag eq/t) over 6.15m from 328.23m to 334.38m, and
    • 99.40g Ag/t, 1.60% Zn, 1.06% Pb and 0.10% Sn (187.52g Ag eq/t) over 12.24m from 360.02m to 372.26m
  • 7.46g Ag/t, 2.51% Zn, 1.02% Pb and 0.06% Sn (129.90g Ag eq/t) over 74.85m from 415.85m to 490.70m
    • 10.80g Ag/t, 0.12 g Au/t, 4.96% Zn, 1.49% Pb and 0.06% Sn (229.62g Ag eq/t) over 16.86m from 430.99m to 447.85m
    • 13.86g Ag/t, 4.20% Zn, 2.35% Pb and 0.34% Sn(277.75g Ag eq/t) over 7.76m from 457.31m to 465.07m

Hole DSB-65 collared 100m west of hole DSB-66 intersected the highest-grade silver sample intersected thus far at Iska Iska in an 80+m wide well mineralized zone as follows:

  • 118.86g Ag/t, 0.35% Zn, 0.35% Pb and 0.15% Sn (152.29g Ag eq/t) over 81.28m from 353.49m to 434.77m including:
    • 5,080g Ag/t, 0.12 g Au/t, 0.26% Zn, 1.34% Pb, 1.53% Cu and 1.27% Sn (4,746.46g Ag eq/t) over 1.46m from 362.53m to 363.99m
  • Cutting of this very high Ag sample to 1,000g Ag/t based on a statistical probability plot yields a still high average for the 81.28m interval of 45.58 g Ag/t with an overall grade of 87.80 g Ag eq/t
  • This very high-grade sample highlights the potential for Iska Iska to host extraordinary grades within the overall extensive mineralized system.

Hole DSB-67 collared 200m south-southwest of DSB-66 intersected a wide zone of mineralization grading 8.17 g Ag/t, 1.40% Zn, 0.48% Pb and 0.06% Sn (79.08g Ag eq/t) over 236.13m from 240.04m to 476.17m including higher grade zones of:

  • 2.17g Ag/t, 0.16 g Au/t, 2.65% Zn, 0.52% Pb and 0.06% Sn (118.18g Ag eq/t) over 9.03m from 249.09m to 258.12m and
  • 28.10g Ag/t, 4.25% Zn, 1.67% Pb and 0.17% Sn (245.05g Ag eq/t) over 19.45m from 434.06m to 453.51m

Hole DSB-60 intersected a 158.58m long zone of lower grade mineralization with higher-grade zones as follows:

  • 16g Ag/t, 0.66% Zn, 0.41% Pb and 0.09% Sn (63.23g Ag eq/t) over 158.58m from 15.33m to 173.91m including:
    • 23.31g Ag/t, 1.18% Zn, 0.56% Pb and 0.16%Sn (105.56 g Ag eq/t) over 6.16m from 34.99m to 41.15m and
    • 115.54g Ag/t, 1.45% Zn and 1.67% Pb (201.17g Ag eq/t) over 4.54m from 139.32m to 143.86m

Hole DSB-63, the eastern most hole in the definition drill program, intersected a significant Sn intersection of 23.37 g Ag/t, 1.77% Zn. 1.22% Pb and 0.51% Sn (205.57g Ag eq/t) over 23.02m from 446.10m to 469.12m. This area is in the Polymetallic (Ag-Zn-Pb) Domain where Sn values have typically been low. This suggests potential to extend the higher-grade Sn zone further east.

Hole DSB-64, the southwestern most hole in the definition drill program, intersected 113.33g Ag/t and 0.12 g Au/t (110.97 g Ag eq/t) over 22.91m from 35.22m to 58.13m and 172.37 g Ag/t and 0.17% Pb% (161.78g Ag eq/t) over 13.46m from 135.83m to 149.29m. This hole was terminated at 240m due to faulting short of its planned depth of 500m.

Note: True width is approximately 80% of core length. Silver equivalent (Ag eq) grades are calculated using 3-year average metal prices of Ag = US$22.52/oz, Zn = US$1.33/lb , Pb = 0.95/lb and Sn = US$12.20/lb, and preliminary metallurgical recoveries of Ag = 88%, Zn = 87%, Pb= 80% and Sn = 50%. Au and Cu assay results are provided as they are of potential economic interest however these values are not included in the Ag eq calculation as metallurgical recovery has not yet been established for these elements. In selecting intervals, a cutoff grade of 30 g Ag eq/t has been used. Lower grade material may be included in intersections where geological continuity is warranted.

The inaugural MRE for Iska Iska outlined in the NI 43-101 Technical Report (see Eloro press release dated October 17, 2023) has been prepared by Micon International Limited. Independent QPs for the Technical Report are Charley Murahwi, P.Geo., FAusIMM, Richard Gowans, P.Eng., Ing. Alan J. San Martin, MAusIMM (CP) and Abdul Aziz, Drame, P.Eng., all of whom are independent QP’s as defined by NI 43-101. Mr. Murahwi completed site visits in January 2020 and November 2022.

Dr. Bill Pearson, P.Geo., Vice President Exploration, Eloro and a QP as defined by NI 43-101 has reviewed and approved the technical content of this news release. Dr. Pearson who has more than 48 years of worldwide mining exploration, development and production experience, including extensive work in South America, manages the overall technical program, working closely with Dr. Osvaldo Arce, P.Geo. General Manager of Eloro’s Bolivian subsidiary, Minera Tupiza S.R.L., and a Qualified Person in the context of NI 43-101, who has supervised all field work carried out at Iska Iska.

Eloro utilized both ALS and AHK for drill core analyses, both of whom are major international accredited laboratories. Drill samples sent to ALS were prepared in both ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia and the preparation facility operated by AHK in Tupiza with pulps sent to the main ALS Global laboratory in Lima for analysis. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Drill core samples sent to AHK Laboratories were prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is followed the same analytical protocols used as with ALS and with the same QA/QC protocols.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 100% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020, Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu over 166m including 446 g Ag/t, 9.03% Pb and 1.16% Sn over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the initial discovery hole DHK-15 which returned 29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu and 0.056%Sn over 257.5m, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined an extensive target zone. On October 17, 2023, Eloro filed the NI 43-101 Technical Report outlining the initial inferred MRE for Iska Iska, prepared by Micon International Limited. The MRE was reported in two domains, the Polymetallic (Ag-Zn-Pb) Domain which is primarily in the east and south of the Santa Barbara deposit and the Tin (Sn-Ag-Pb) Domain which is primarily in the west and north. The Polymetallic Domain is estimated to contain 560Mt at 13.8 g Ag/t, 0.73% Zn & 0.28% Pb at an NSR cutoff of US$9.20 for potential open pit and an NSR cutoff of US$34.40 for potential underground. The majority of the mineral resource is contained in the constraining pit which has a stripping ratio of 1:1.

The Polymetallic Domain contains a higher-grade mineral resource at a NSR cutoff of $US25/t of 132 million tonnes at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t which has a net NSR value of US$34.40/t which is 3.75 the estimated operating cost of US$9.20/t. The Tin Domain which is adjacent the Polymetallic Domain and does not overlap, is estimated to contain a mineral resource of 110Mt at 0.12% Sn, 14.2 g Ag/t and 0.14% Pb but is very under drilled.

The Company has completed a 5,267.7m definition drill program to upgrade and expand the higher-grade mineral resource in the Polymetallic Domain and has commenced a preliminary economic evaluation (PEA) led by Lycopodium.

Eloro: Infill Drilling, Bulk Samples and Silver/Zinc/Tin at Iska Iska in Bolivia

Eloro (ELO.T) CEO, Tom Larsen, has a huge job: he has to explain the geology and commercial potential of the Iska Iska project in Bolivia. An interview with Larsen needs to cover a lot of ground beginning with the market reaction to the company’s most recent news release.

“We need to get back to $3.00 to $4.00,” said Larsen. “We were hurt badly when the regulator would only allow us to use Net Smelter Return rather than silver equivalent which is more common and better understood in our first Mineral Resource Estimate.”

As Bob Moriarty puts it at 321Gold.com, “the change in nomenclature cost investors $129 million or a loss of 55% of what the company was worth in August.”

The regulator was part of the story, the other part was the statistical effect of widely spaced drill holes. It’s a complicated subject but, bottom-line, to improve the modelled resource ELO needed to drill 40 to 50-meter spaced “infill” holes and the first of those holes were reported in the most recent release.

The mineralization encountered in these infill holes is impressive. The headline hole came in with 62.84 meters of 339.82g silver equivalent per ton rock with many other high silver equivalent intervals in this and other holes. As Larsen commented in the release, “They demonstrate substantive higher-grade intervals, especially for silver, in the potential starter pit mineral resource area that may now be potentially upgraded and expanded.”

There are still six infill holes to be reported which will give Eloro further confirmation for an updated, and upgraded, revised MRE. “We want to do it soon,” said Larsen. “But it has to be right.”

“We’re seeing better grades,” said Larsen. “And as grade goes up, especially in the deeper sections of the starter pit, tonnage increases.”

At the same time, work has been progressing on the 10,000 kilos of bulk sampling taken from the metallurgical holes drilled earlier in September. “We shipped this material to Cornwall for metallurgical testing and some of it was sent to TOMRA in Germany for testing with the XRT ore sorting technology we want to deploy,” said Larsen. “These bulk samples will give results which are more indicative than smaller bore drill holes.”

The XRT ore sorter testing is important to the economics of any potential mine. The starter pit at Iska Iska already has a very low 1:1 strip ratio and with sorting technology much of the lower grade rock will be stockpiled when it comes to processing the material. Which, in turn, decreases the CAPEX of the project.

The starter pit at Iska Iska is currently seen as a silver/polymetallic operation. But, at a more granular level, there are different domains. To the North East zinc/silver is the predominant base metal, to the South West there is less zinc and more tin/silver.

A zinc/silver concentrate has become much more interesting as Chinese interests are planning to build two large zinc processing facilities in collaboration with the Bolivian government. 1.5 billion dollars worth of zinc processing will come online in the next three years. These sorts of plants need reliable feedstock and may give Eloro a chance to maximize the return on its zinc/silver concentrate. Typically, plant investments of this size will try to secure supply with multi-year offtake agreements. The zinc/silver resource at Iska Iska could prove to be the largest source of feed in Bolivia.

The tin/silver side of the Iska Iska equation remains a work in progress. “We are seeing higher grades of tin as we drill further south,” said Larsen. “We’re adding tin zones.”

The tin grade is important but what Eloro needs to see is tonnage. Processing the tin requires a “fuming” plant which runs 30-40 million dollars and there has to be enough tonnage to justify the investment.

“We will continue to definition drill to improve the MRE,” said Larsen. “Iska Iska is good rock. We’re not running into any deleterious material, no arsenic. We’re able to drill a hundred meters a day per drill. We want to do more infill drilling and more metallurgical holes. We’re seeing better silver grades in the met holes. Much better.”

The fact is that ELO is doing Preliminary Economic Analysis level work while it is updating its Mineral Resource Estimates. Which actually makes a lot of sense as Iska Iska is so big and so richly endowed that the MRE’s need to be prepared for the deposit one section at a time. Figuring out the “starter pit”, drilling the infill and doing the metallurgy and XRT sorting analysis keeps Eloro geos and consultants very busy. However, as CEO, Larsen also has to consider how best to commercialize the deposit, line up potential partners and maximize the value of Iska Iska for his shareholders.

Getting set back by an overcautious regulator’s requirements had hit the Eloro share price but it changes nothing about the huge Iska Iska deposit. The share price has been marching back as tax selling tapered off. The share price should continue to come back in the New Year as Larsen releases the results of more infill holes, an updated MRE, perhaps an updated and revised MRE and then a PEA later in the year.

“We want to show a billion tons of commercial material,” said Larsen. It is not an idle boast. Tom backed it up with $39,000 in personal market buying from $2.16 to $2.43 reported Christmas Eve.

Eloro Resources Intersects 279.22 g Ag/t, 0.47% Pb and 0.43% Sn (339.82g Ag eq/t) over 62.84m in Definition Drilling at the Iska Iska Project, Potosi Department, Southwestern Bolivia

Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce the first assay results from five (5) of the drill holes in its eleven (11) hole 5,267.7m definition drill program on the Iska Iska silver-tin polymetallic project in the Potosi Department of southwestern Bolivia.

Tom Larsen, CEO of Eloro commented: “These latest drill hole results are very encouraging. They demonstrate substantive higher-grade intervals, especially for silver, in the potential starter pit mineral resource area that may now be potentially upgraded and expanded.”

Larsen continued, “Significant tin is present in several holes with grades up to 0.5 percent, highlighting the chances to expand and increase the grade of the tin resource which is a high priority exploration target in 2024. As we expected, the higher-grade silver and tin intercepts from this definition drill program are demonstrating selective higher-grade metal zonation within the starter pit area and the Tin (Sn-Ag-Pb) Domain. We expect to release results from the six (6) remaining definition drill holes in the first part of January 2024, concluding our first phase infill definition drilling program aimed to enhance grade and expand tonnage in the Santa Barbara starter pit area.”

The definition diamond drill program focussed on upgrading and expanding the higher-grade Polymetallic (Ag-Zn-Pb) Domain Type inferred mineral resource, which as previously reported (see Eloro press release dated October 17, 2023) contains an inferred mineral resource of 132 million tonnes at 24.3 g Ag/t, 1.11% Zn and 0.50% Pb (72.06 g Ag eq/t) at an NSR cutoff of $US25/t. The net NSR value of this higher-grade resource is US$34.40/t which is 3.75 times the estimated operating cost of US$9.20/t.   Several of these holes also tested the adjacent Tin (Sn-Ag-Pb) Domain where high values of silver (Ag) have previously also been obtained in addition to tin.

Dr. Bill Pearson, P.Geo. Executive Vice President, Exploration said: “The bulk of mineralization at Iska Iska, especially the high-grade Ag zones, occur within veins, vein breccias and veinlets that overall have a general west-northwest trend (300o). Channel sampling of a typical high-grade structure in the Santa Barbara adit (see Eloro press release dated April 21, 2021) returned 165 g Ag/t, 3.46% Pb and 0.46% Sn (310.25g Ag eq/t) over 166m which included a very high-grade section of 446 g Ag/t, 9.03% Pb and 1.16% Sn (817.38g Ag eq/t) over 56.19m. This gives an excellent indication of the potential strike length of these high-grade Ag structures, as well as the potential for bonanza-type grades in them. Closer spaced drilling as expected, provides a better definition of these important mineralized structures, especially those with higher grade silver, which has the potential to increase the overall resource grade as well as expand resource tonnage.”

Pearson continued: “Work is continuing on the “ore-sorting” tests with metallurgical work on the concentrate samples produced at TOMRA in Germany being completed at Wardell Armstrong in Cornwall. In addition, our geophysicists are processing new IP data which will provide important information on potential extensions of the remarkable Iska Iska mineralizing system.”

Table 1 below lists significant results for the five drill holes reported. Figure 1 shows locations of all the definition drill holes completed with the holes with results released highlighted. Silver equivalent (g Ag/t) has been calculated using 3-year average metal prices and preliminary metallurgical recoveries (see note below Table 1 for more information).

DEFINITION DRILL PROGRAM

The definition drill program has been designed to fill-in major gaps in the block model as well as upgrade and expand the higher-grade zone both along and across strike in the general area of the potential starter pit. As noted by Micon International Limited, authors of the National Instrument 43-101 (“NI 43-101”) Technical Report detailing the initial Iska Iska mineral resource estimate (“MRE”)(see Eloro press release dated October 17, 2023), the highest-grade areas are also the best drilled. As drill density in the deposit is improved, it is expected that grade will increase due to better sample density. Initial results reported herein confirm that this is likely the case.

Table 2 lists the coordinates of the Definition Drill Holes with assay results reported in this release and holes for which assay results are pending. Figure 1 shows the locations of the definition drill holes with holes reported in this release highlighted in yellow.

Qualified Person (“QP”)

The inaugural MRE for Iska Iska outlined in the NI 43-101 Technical Report (see Eloro press release dated October 17, 2023) has been prepared by Micon International Limited. Independent QPs for the Technical Report are Charley Murahwi, P.Geo., FAusIMM, Richard Gowans, P.Eng., Ing. Alan J. San Martin, MAusIMM (CP) and Abdul Aziz, Drame, P.Eng., all of whom are independent QP’s as defined by NI 43-101. Mr. Murahwi completed site visits in January 2020 and November 2022.

Dr. Bill Pearson, P.Geo., Vice President Exploration, Eloro and a QP as defined by NI 43-101 has reviewed and approved the technical content of this news release.   Dr. Pearson who has more than 48 years of worldwide mining exploration, development and production experience, including extensive work in South America, manages the overall technical program, working closely with Dr. Osvaldo Arce, P.Geo. General Manager of Eloro’s Bolivian subsidiary, Minera Tupiza S.R.L., and a Qualified Person in the context of NI 43-101, who has supervised all field work carried out at Iska Iska.

Eloro utilized both ALS and AHK for drill core analyses, both of whom are major international accredited laboratories. Drill samples sent to ALS were prepared in both ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia and the preparation facility operated by AHK in Tupiza with pulps sent to the main ALS Global laboratory in Lima for analysis. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Drill core samples sent to AHK Laboratories were prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is followed the same analytical protocols used as with ALS and with the same QA/QC protocols.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 100% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020, Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu over 166m including 446 g Ag/t, 9.03% Pb and 1.16% Sn over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the initial discovery hole DHK-15 which returned 29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu and 0.056%Sn over 257.5m, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined an extensive target zone. On October 17, 2023, Eloro filed the NI 43-101 Technical Report outlining the initial inferred MRE for Iska Iska, prepared by Micon International Limited. The MRE was reported in two domains, the Polymetallic (Ag-Zn-Pb) Domain which is primarily in the east and south of the Santa Barbara deposit and the Tin (Sn-Ag-Pb) Domain which is primarily in the west and north. The Polymetallic Domain is estimated to contain 560Mt at 13.8 g Ag/t, 0.73% Zn & 0.28% Pb at an NSR cutoff of US$9.20 for potential open pit and an NSR cutoff of US$34.40 for potential underground. The majority of the mineral resource is contained in the constraining pit which has a stripping ratio of 1:1.

The Polymetallic Domain contains a higher-grade mineral resource at a NSR cutoff of $US25/t of 132 million tonnes at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t which has a net NSR value of US$34.40/t which is 3.75 the estimated operating cost of US$9.20/t. The Tin Domain which is adjacent the Polymetallic Domain and does not overlap, is estimated to contain a mineral resource of 110Mt at 0.12% Sn, 14.2 g Ag/t and 0.14% Pb but is very under drilled.

The Company has completed a 5,267.7m definition drill program to expand the higher-grade mineral resource in the Polymetallic Domain and has commenced a preliminary economic evaluation (PEA) led by Lycopodium.
