Denarius Metals (DSLV.V) is a vehicle for mining entrepreneur Serafino Iacono and his team as they moved on from GCM Mining as that company was absorbed by Aris Mining. A long time member of that team was Denarius CFO Mike Davies who I spoke with June 13.

“We changed the name from Denarius Silver to Denarius Metals,” said Davies. “We now have three projects, Lomero-Poyatos deposit is located in the north-east part of the Spanish/Portuguese Iberian Pyrite Belt, our recently optioned earn-in zinc project, Toral in Northern Spain and our Zancudo silver-gold project in Colombia.”

“The Colombia project is a bit of a sleeper,” said Davies. “We retained 100% of the project when IAMGOLD decided to walk away as it was not a core priority to them. It is in a historical mining area in Colombia, has a historical mine and 40,000 meters of drilling.”

“Our plan is to get the old workings back into production using a contract miner. We’re aiming for early 2024,” said Davies. “We have to update the permits and figure out who will process the material. The goal is to produce 500 tons a day, crush it and, maybe, concentrate it. The resource contains 6 gpt gold and 100 gpt silver.”

With the team’s long experience in Colombia, Davies points out that Denarius is very involved with the communities in the area. “We’re working with the communities. One thing we are doing is building a bypass road to avoid our trucks driving through towns. We’re fortunate that it is a historical mining district so we are not anticipating negative reaction from the communities.”

While Denarius’ roots are in Colombia, for juniors the world is prospective. Spain, with its rich mining history, was a natural fit because of its culture. “The Iberian Pyrite Belt is a prolific mining district,” said Davies. It has been prolific since the time of the Roman Empire when it was a source for gold, silver, copper, tin and lead. The belt remains the largest concentration of massive sulphites in the world. Denarius’ Lomero-Poyatos deposit is on the northern edge of the Belt and is nearby several, large, producing mines.

Lomero-Poyatos has been the scene of mining and exploration activity since the late 1800s. There are eight levels of, now flooded mine workings. There are also thousands of meters of drill core, some better logged than others but representing a significant knowledge base. As well, gravimetric and resistivity studies have been conducted on the property. (This is all detailed in SRK Consulting’s comprehensive NI 43-101 Technical Report Mineral Resource Estimate submitted in late 2022 and press released November 2, 2022.)

“When we became interested in Lomero-Poyatos we knew it was high grade but it was stuck in bankruptcy,” said Davies. “There was an investigation permit in place and we bought out the creditors. There was an adjacent dormant exploration permit at Palomarejo and we were also able to get a clean permit there for three years.”

With this permit and ownership, Denarius set to work on its Phase 1, 26,000 meter, 83 hole, validation and infill drilling program. “This program gave us confidence in our model,” said Davies. “The MRE confirmed at least 10.7 million tons of material. We went on to Phase 2 which was completed in February. We drilled 13,225 meters in 42 holes.  We got the results in May. Higher grades.”

Commenting in the press release announcing these results, Serafino Iacono, Executive Chairman and CEO stated, “We are encouraged by the Phase 2 drill assays validating the lateral and horizontal continuity of the massive sulphide and semi-massive sulphide mineralized lenses and confirming the presence of higher-grade mineralized zones within the broader resource envelope.”

“We’ve moved on to Phase 3 drilling which comprises 4,000 meters of infill drilling and 6,000 meters of “greenfield” drilling to test for extensions of the deposit,” said Davies. “When we complete the 4,000 meter phase we’ll update the MRE and get to work pushing a Preliminary Economic Analysis (PEA) out for the project by the end of this year.”

In November 2022, Denarius announced another Spanish venture. The Toral Zn-Pb-Ag Project, Leon Province, Northern Spain is subject to an earn in agreement with Denarius which is just getting underway. “The main focus is zinc,” said Davies. “We are looking at 20 million tons of material.” It is early days at Toral for us as we get on with exploring and expanding what looks like a rich, polymetallic, potential resource.

Denarius has put a lot on its plate but its management has put their money into the project, “Management owns 23% of the company, Aris owns 17%,” said Davies, “And if you look at the insider reports, Serafino is buying in the open market for his own account.”

With a little less than 60 million shares out and a market cap of $34,790,000, Denarius is very much worth a look at its current price of $0.59.

Denarius Metals Corp. (TSXV: DSLV) (OTCQX: DNRSF) (“Denarius Metals” or “the Company”) announced today that it has received the final assays for 42 drill holes, mainly in-fill holes, totaling approximately 13,225 meters, from the Phase 2 surface validation and in-fill drilling program on its polymetallic Lomero Project in southern Spain. To date, Denarius Metals has completed approximately 41,850 meters of drilling in 128 drill holes, including twinning of historical drill holes. The in-fill phase, totaling 23,920 meters and representing 57% of the total drilling program, is now complete. A final 4,000 meters validation drilling campaign, designed to finish verifying the high-grade underground drill holes drilled in the 1980s by Indumetal/Billiton, is in progress. The full drilling results will be incorporated into the geological model and will be integrated in the Mineral Resource Estimate (“MRE”) update to be completed in conjunction with a preliminary economic assessment (“PEA”) in the second half of 2023.

Key takeaways from the exploration work carried out at the Lomero Project to date include:

• Phase 2 validation and in-fill drill holes completed on the central part of the deposit have mostly intersected significant copper mineralization in massive sulphides, showing better grades than the Cu average grade of the current MRE, ranging from 0.6% up to 1.86% over intervals up to 15.70 meters thick;
• Phase 2 in-fill drill holes completed on the eastern part of the deposit have intersected significant zinc and lead mineralization showing much better grades than the Zn and Pb average grades of the current MRE, ranging for Zn from 1.08% up to 11.01% over intervals up to 6.65 meters thick, and for Pb from 1.55% to 5.05% over intervals up to 6.65 meters thick. In-fill drilling has also, confirmed high zinc and gold grades over widths that widen to depth at the westernmost end of the permit. Zinc and lead mineralization is hosted primarily in the massive sulphide domain and, to a lesser extent, in the semi-massive sulphide domain;
• Validation by directional drilling of the underground drilling program completed in the 1980s by Indumetal/Billiton in short < 60 m horizontal holes from underground stations was successful in returning exceptional high grades from the polymetallic mineralization hosted in the lower part of the historical mine, with drill hole LPDV002 intersecting 10.25 meters grading 0.27% copper, 4.79% lead, 9.82% zinc, 161 g/t Ag and 6.82 g/t Au;
• A PEA-level metallurgical testwork program commenced in April 2023 at Grinding Solution UK’s facilities. The testwork will be completed using two separate composites, one semi-massive sulphide and one massive sulphide, with samples collected from drill cores produced during the Company’s Phase 1 and Phase 2 drill campaigns.

Serafino Iacono, Executive Chairman and CEO of Denarius Metals, commented, “We are encouraged by the Phase 2 drill assays validating the lateral and horizontal continuity of the massive sulphide and semi-massive sulphide mineralized lenses and confirming the presence of higher-grade mineralized zones within the broader resource envelope. In addition, the initial drill assays from the validation drilling program in process are very promising and could potentially increase the grades in the current geological model. For the balance of 2023, activities at the Lomero Project will be focused on completion of the PEA, additional engineering studies to support the future development of the project and execution of the planned greenfield exploration program. The greenfield exploration program comprises 6,000 m of drilling aimed at increasing the tonnage of the MRE update based on Phase 1 and Phase 2 drilling, targeting the Las Merinas and Alianza areas located along two main shear zones discovered in 2022 by field mapping, located to the south and to the north of the shear zone that hosts the Lomero-Poyatos deposit and both of which are E-W trending.”

The Phase 2 surface validation and in-fill drilling program commenced in October 2022 and was completed in February 2023. It was designed to validate some selected historical in-fill holes drilled by Corporacion de Recursos Iberia (CRI) in 2013 within the central sector of the existing mine and then conduct 50×50 m in-fill drilling to confirm the continuity of widths and grades within the massive sulphide and semi-massive sulphide lenses to upgrade the Inferred MRE to the Indicated category. Extension drilling was also carried out in 3 holes totaling 1,815 meters aimed at testing the combined TEM and gravity anomalies that occur down-dip of the main shear-zone hosting the Lomero-Poyatos deposit.

Key Highlights

• Validation and in-fill drill holes completed on the central part of the deposit mostly showed cupriferous mineralization with maximum intersection grades of 1.86% Cu, 21 g/t Ag and 2.85 g/t Au over 6.70 meters (LM22091), 1.23% Cu, 7 g/t Ag and 1.67 g/t Au over 15.70 meters, including 1.65 meter at 1.86% Cu, 15 g/t Ag and 0.61 g/t Au (LM22085), and 1.43% Cu, 16 g/t Ag and 1.34 g/t Au over 6.30 meters (LM22084).
• In-fill drill holes completed on the eastern part of the deposit mostly showed significant zinc and lead mineralization with maximum intersection grades of 6.12% Pb, 11.01% Zn, 95 g/t Ag and 4.01 g/t Au over 2.50 meters (LM22110), 3.43% Pb, 7.54% Zn, 88 g/t Ag and 5.30 g/t Au over 2.30 meters (LM22113), and 3.68% Pb, 3.56% Zn, 127 g/t Ag and 5.62 g/t Au over 1.70 meters (LM22116). Drill hole LM23103 confirms high zinc and gold grades at depth at the westernmost end of the permit, returning 0.32% Cu, 0.95% Pb, 2.04% Zn, 37 g/t Ag and 3.79 g/t Au over 6.65 meters, including 2.15 meters at 0.40% Cu, 1.29% Pb, 2.66% Zn, 52 g/t Ag and 5.09 g/t Au, demonstrating that the deposit remains open to the west.
• Validation by directional drilling of the underground drilling program completed in the 1980’s by Indumetal/Billiton using a series of short < 60 m horizontal holes from underground stations was successful in confirming the high-grade polymetallic mineralization present in the lower part of the historical mine, with drill hole LPDV002 intersecting 10.25 meters grading 0.27% Cu, 4.79% Pb, 9.82% Zn, 161 g/t Ag and 6.82 g/t Au. Polymetallic mineralization is entirely hosted in the massive sulphide domain. Although, the same validation program failed to confirm the unusually wide historical intersections, in consensus with SRK Consulting (U.S.), Inc., the decision was made to continue the program by conventional inclined diamond drilling to speed up drilling, targeting key intersections from the historical program.
• Extension drill hole LM22115, designed to test the combined TEM and gravity anomalies that occur well below the in-fill drilling carried out so far, intersected a wide zone of thin, dense veinlets, hosted by a much wider stockwork interval, showing trace chalcopyrite and coarse pyrite mineralization filling black chlorite-altered schistosity planes, returning low-grade Au mineralization of 16.10 meters at 0.13 g/t Au. This intercept is interpreted to be of a vertically extensive stringer feeder below the massive sulphide and semi-massive sulphide lenses. Drill holes LM22121 and LM22122 didn’t return any significant Au values.
• The ongoing metallurgical test work program is testing two separate composites, one semi-massive and one massive sulphide, aimed at optimizing the base metal floatation on representative composites with the average deposit grade. The test work is expected to be completed by mid- 2023.

The following table lists the key intercepts from the Phase 2 validation and in-fill drilling program since the issuance of the current MRE with an effective date of July 19, 2022:

Notes:

(1) The holes were drilled at -45 to -80 degrees from the horizontal. Grades are for semi-massive sulphide to massive sulfide intersections and some stockwork and shear zones. Sample interval grades over CuEq >1% are reported. The width is the sample length and is not necessarily the true width of the intersection. All base and precious metal grades are uncut and are not diluted to a minimum mining width.

(2) The following holes returned intervals grading <1% CuEq and so are not listed in the table: LM22092, LM22094, LM22101, LM22102, LM22106, LM22107; LM22108, LM22111, LM22114, LM22115, LM22117, LM22118, LM22121 and LPDV003.

(3) Equivalent copper grade (CuEq%) was calculated using prices of US$1,800/oz gold, US$25/oz silver, US$3.55/lb copper, US$1.00/lb zinc and US$0.90/lb lead. No adjustments were made for recovery as the project is at an exploration stage and metallurgical data to allow for estimation of recoveries is not yet available.

(4) MS: massive sulfides; SM: semi-massive sulfides; STKW: stockwork; DISS: disseminated; SH: shear-zone.

(5) LM22100 partial reassays by ALS are pending (see QAQC below).

Please refer to the attached illustrative images (Attachments 1 to 7) showing (i) the location of drill holes, (ii) the location of the best copper, lead and zinc drill holes and (iii) five cross sections for drill holes LM22084, LM22088, LM22120, LPDV002, LM22115.

Qualified Persons Review

Dr. Stewart D. Redwood, PhD, FIMMM, FGS, Senior Consulting Geologist to the Company, is a qualified person as defined by National Instrument 43-101 – Standards of Disclosure or Mineral Projects and prepared or reviewed the preparation of the scientific and technical information in this press release. Verification included a review of the quality assurance and quality control samples, and review of the applicable assay databases and assay certificates.

Quality Assurance and Quality Control

The Lomero-Poyatos samples were prepared by ALS Labs (ISO/IEC 17025:2017 and ISO 9001:2015) at their facilities in Seville, Spain and assayed in Clonmel, Ireland. Gold was assayed by 30 g fire assay with AAS finish, while silver and base metals were analyzed in a multi element analysis of base metal ores and mill products by strong oxidizing digestion and ICP-AES finish. Blank, standard and duplicate samples were routinely inserted and monitored for quality assurance and quality control.

As part of its Quality Assurance and Quality Control procedures, Denarius Metals sent 331 pulps and coarse rejects at the end of Phase 2 of drilling to ALS Labs for umpire analysis to check the results from the primary laboratory, AGQ. The results from ALS showed excellent correlation for all elements for Phase 1 drilling. However, certain deviations were observed for the Phase 2 drilling results, in particular for gold fire assay and lead. Following a thorough review of internal laboratory QA/QC procedures, and confirmation assays received from a third laboratory, SGS in Huelva, Spain, the Company decided to send 100% of sample pulps from the massive and semi massive sulphide zones, plus 50% of the stockwork zones, from the Phase 2 drilling to ALS for check assays. In addition, 20% of massive sulphide samples, 10% of semi-massive sulphide samples, and 5% of stockwork samples from Phase 1 of drilling were sent to ALS for check assays. A total of 514 samples were sent to ALS for check assays.

The check assays received from ALS confirmed that Phase 1 results, as reported by the Company, are reliable. However, the check assays confirmed that there is a bias in the Phase 2 assays of the primary laboratory for gold and lead. Therefore, the AGQ results for Phase 2 were discarded and it was decided only to use results from ALS for Phase 2 drilling. The remainder of the Phase 2 stockwork zone samples are currently being reassayed by ALS for completeness. This affects one significant intersection in hole LM22100 which is reported in the table above as pending reassay results. However, given the low-grade nature of the stockwork mineralization, it is not anticipated the results will demonstrate any material differences. In addition, ALS has been designated as the primary laboratory for all future assays.

Triple Flag Precious Metals

The Company is pleased to report that Triple Flag Precious Metals Corp. has now forwarded the Tranche 2 payment of C$5 million pursuant to the royalty facility of the Thunder Bay North Project, previously reported (Press release December 19, 2022).

Abraham Drost, CEO stated: “The new combined Mineral Resource Estimate (“MRE”) for the Escape and Current deposits comprising the Thunder Bay North Critical Metals Project is now complete. Work will continue to determine viability of a potentially bulk mineable, ramp accessible underground constrained mineral resource. Run rates, production sequencing and preliminary economics of the new MRE are presently being scoped internally in preparation to continue technical studies. The Inferred mineralization suggests that the Current and Escape deposits are open and that the underexplored remainder of the two host magma conduits have the potential to add additional mineral resources.

The Thunder Bay North Critical Metals Project is a potential domestic North American source of platinum, palladium, copper and nickel. Federal and provincial governments have placed a strong focus on bolstering the domestic critical mineral supply chain in North America. We are very pleased that Triple Flag Precious Metals has completed Tranche 2 of a previously announced royalty financing to facilitate potential development, together with our Indigenous partners, of a sustainable critical metals mining project at Thunder Bay North.”

2023 Exploration Update

A total of 73,990 m in 171 holes were drilled by the Company from 2020-2023 for a total drilling database of 105,086 m in 266 holes which support the new Mineral Resource Estimate at the Escape Deposit.

Similarly, a total of 17,172 m in 78 holes were drilled by the Company from 2020-2023 for a total drilling database of 179,630 m in 818 holes drilled variously in 2006 – 2015 and 2020 -2023 which support the new Mineral Resource Estimate at the Current Deposit.

Mineral Resource Estimate

Block models for the Current and Escape Deposits were created by SLR using Seequent’s Leapfrog Geo and Edge using drilling and assays results as of April, 2023.  Wireframes for the ultramafic chonolith were generated based on logged lithologies and chromium assays.  Higher grade mineralization wireframes were generated at a 1.0 g/t Pt + Pd cut-off grade with lower grades included to maintain continuity.  Assays were composited to 2 m lengths and were used for block estimation on an uncapped basis.  Pt, Pd, Au, Ag, Cu, Ni and density were interpolated using Ordinary Kriging (OK) into blocks measuring 5.0 m by 5.0 m by 2.5 m.  Inverse Distance Squared (ID2) and Nearest Neighbour estimates were run for validation purposes.  Blocks were classified following CIM Definitions (2014) as Indicated and Inferred using drill hole spacing based criterion.  Indicated Mineral Resources were based on a nominal drill hole spacing of 50 m.  Mineral Resources have been reported within underground reporting shapes based on an NSR cut-off value of US$48/tonne.  A crown pillar exclusion of 20 m from the bottom of the overburden below lakes and the underground reporting shapes used during reporting ensure that the Mineral Resources meet the minimum requirements for Reasonable Prospects of Eventual Economic Extraction (RPEEE).

NSR and Mineral Resources Cut-off Value

NSR values have been estimated for an operating scenario that includes production of a split copper sulphide concentrate and a nickel-rich residual sulphide concentrate, each containing payable platinum and palladium, for both the Escape and Current deposits.

Metal prices are based on consensus, long term forecasts from banks, financial institutions, and other sources. The metal prices and other input parameters used in development of a unit NSR value for each block is provided in Table 3.

For the purpose of Mineral Resource reporting, underground constraining shapes were developed using the Deswik Stope Optimizer (DSO) based on an NSR cut-off value of US$48/tonne.  The cut-off parameters, based on previous study work, are provided in Table 4:

Previous Disclosure

In its press release of February 15th 2023, the Company disclosed that initial work on an updated mineral resource estimate indicated the potential for a material reduction in the total metals content of the Current deposit in the range of 20-50%. The Company confirms that on a comparative basis, under the new Mineral Resource Estimate, the Current Deposit is approximately 33% lower in Indicated Pt + Pd Contained Metal and 21% lower in Indicated Cu Contained Metal. Management has begun the process of evaluating the potential options and viability for development of the Thunder Bay North project based on the new mineral resource.

Qualified Persons

The Mineral Resource estimate was prepared by, Sean Horan, P.Geo. (Ontario) and Tudorel Ciuculescu, P.Geo. (Ontario), of SLR Consulting Ltd., independent “Qualified Persons” under National Instrument 43-101- Standards of Disclosure for Mineral Projects. Verification included a site visit to inspect drilling, logging, density measurement procedures and sampling procedures, and a review of the control sample results used to assess laboratory assay quality. In addition, a random selection of the drill hole database results was compared with original records.

Clean Air Metals’ flagship asset is the 100% owned, high grade Thunder Bay North Project, a platinum, palladium, copper, nickel project located near the City of Thunder Bay, Ontario and the Lac des Iles Mine owned by Impala Platinum. The Thunder Bay North Project hosts the twin magma conduit bodies which host the Current and Escape deposits forming the basis for the mineral resource estimate reported herein.

 Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce assay results from the last eight (8) diamond drill holes from the definition drill program at Santa Barbara in the Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. Two (2) of these drill holes (DSB-45 and DSB-47) filled in gaps in previous drilling of the High-Grade Zone. The remaining six (6) holes (DSB-44. DSB-48, DSB-49, DSB-50, DSB-51 and DSB-52) tested the potential south-southeastern extension of the High-Grade Zone at Santa Barbara.

As previously reported in Eloro’s press release dated November 27, 2022, the Company completed 84,495m of drilling in 122 holes to complete the definition drill program in the Santa Barbara target area, as shown in Figure 1. Tables 1 and 2 list significant assay results for the reported drill holes. Prices used for calculating Ag equivalent grades are as outlined in Eloro’s July 21, 2022 press release to maintain consistency with Ag equivalent calculations in previous releases.

Tom Larsen, CEO of Eloro, said: “These latest results, which complete the Santa Barbara definition diamond drill program, have significantly expanded the potential open pittable resource across the valley of the Iska Iska Caldera. Micon International Limited (”Micon”) will be updating the deposit’s inaugural mineral resource model to incorporate these new results. Our geological technical team led by Dr. Bill Pearson, P.Geo. and Dr. Osvaldo Arce, P.Geo., is working closely with Micon to ensure all required information is completed. As recently reported (see Eloro’s press release dated April 4, 2023) additional metallurgical testing is being carried out under the direction of Mike Hallewell, C.Eng., Eloro’s Senior Strategic Metallurgist.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President, Exploration commented: “Drilling is advancing in the Casiterita area as previously outlined to test for the potential tin porphyry (see Eloro’s February 14, 2023 press release). To date, a total of 3,302 metres of diamond drilling has been completed in 9 holes, including two in progress. Assay results from these holes are pending. We have also completed additional surface induced polarization/resistivity (“IP/Res”) surveys on the western side of Santa Barbara. Bore hole IP/Res (“BHIP”) surveys continue to be carried out on drill holes as holes are completed. Regional geological, prospecting and sampling, along with ground magnetic surveys, are being carried out on Eloro’s large land package in the Iska Iska area (see Eloro press release dated November 22, 2022).”

Santa Barbara Definition Drilling

Hole DSB-47 was drilled to test the area immediately southwest of the Santa Barbara Breccia Pipe (“SBBP”) (Figure 1) and returned a 321m long intersection with a number of higher-grade intervals as follows:

• 114g Ag eq/t (9.90g Ag/t, 0.12 g Au/t, 0.96% Zn, and 0.68% Pb) over 320.97m from 59.40m to 380.37m, including higher-grade portions of:
  • 232.30 g Ag eq/t (29.86g Ag/t, 0.22 g Au/t, 0.63% Zn, 2.18% Pb, 0.30% Cu and 0.10% Sn) over 32.02m from 60.90m to 92.92m
  • 147.06 g Ag eq/t (5.41g Ag/t, 1.90% Zn and 0.90% Pb) over 10.66m from 133.89m to 144.55m
  • 184.83 g Ag eq/t (36.83g Ag/t, 1.81% Zn and 1.13% Pb) over 23.82m from 170.30m to 194.12m
  • 243.09 g Ag eq/t (4.48g Ag/t, 0.95 g Au/t, 2.02% Zn and 0.81% Pb) over 13.68m from 218.45m to 232.13m and
  • 249.06g Ag eq/t (18.48g Ag/t, 0.10 g Au/t, 2.34% Zn, 1.74% Pb and 0.11% Sn) over 24.30m from 285.25m to 309.55m

Six (6) holes (DSB-44. DSB-48, DSB-49, DSB-50, DSB-51 and DSB-52) tested the potential south-southeastern extension of the High-Grade Zone at Santa Barbara. All these holes, which were drilled at an azimuth of 225⁰ with a dip of -60⁰, tested and confirmed an additional 300m of potential strike length to the south-southeast. Collectively, these holes intersected many significant intersections within altered and mineralized dacite porphyry, dacite and dacitic breccia.

The most significant holes are the most southernmost three, DSB-50, DSB-51 and DSB-52, which each returned well mineralized intersections over 100m in core length as follows:

• 86.67g Ag eq/t (13.57g Ag/t, 0.99% Zn and 0.41% Pb) over 105.42m including 193.50 g Ag eq/t (15.34g Ag/t, 3.22% Zn and 0.17% Pb) over 10.57m (DSB-50)
• 103.03g Ag eq/t (5.18g Ag/t, 1.72% Zn and 0.21% Pb) over 143.06m including 175.06 g Ag eq/t (9.39g Ag/t, 2.96% Zn and 0.35% Pb) over 49.87m (DSB-51)

• 123.28g Ag eq/t (7.46g Ag/t, 0.14 g Au/t, 1.85% Zn and 0.26% Pb) over 119.77m including 306.28 g Ag eq/t (18.03g Ag/t, 0.45g Au/t, 4.55% Zn and 0.47% Pb) over 28.79m (DSB-52)

Drill holes in the south-southeastern extension of the Santa Barbara Deposit are notably Zn-rich returning some of the highest Zn values intersected thus far. These three holes expand the strike extent of the Santa Barbara High-Grade Zone to more than 1,100m significantly expanding the potential open pittable resource. The High-Grade zone is now 800m across and is open along strike to the south-southeast.

In addition to the results cited above, all six holes drilled in the southeasternmost part of the target area returned numerous additional reportable intersections which are listed in detail in Table 2.

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites, it is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling and geological modelling.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows: (Prices updated as of July 21, 2022, to more accurately reflect current metal prices):

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Metallurgical tests are in progress by Blue Coast Research to establish levels of recovery for each element reported. The preliminary phase of Ag, Zn and Pb testwork is complete but additional development and optimization will be required. Metallurgical testing is in progress to establish Sn recovery. Future geo-metallurgical programs will also include studies to understand the deportment of other potential metals such as gold, copper, bismuth and indium. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Eloro is utilizing both ALS and AHK for drill core analysis, both of whom are major international accredited laboratories. Drill samples sent to ALS are 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. More recently Eloro has had ALS send pulps to their laboratory at Galway in Ireland. 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 are prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Au and Sn analysis on these samples is done by ALS Bolivia Ltda in Lima. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is following the same analytical protocols used as with ALS and with the same QA/QC protocols. Turnaround time continues to improve, as laboratories return to more normal staffing levels.

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 DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53 g Ag/t, 0.078g Au/t, 1.45% Zn, 0.59% Pb, 0.080% Cu, 0.056% Sn, 0.0022% In and 0.0064% Bi 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 442 g Ag eq/t (164.96 g Ag/t, 0.46% Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (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, 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. In its September 20, 2022 press release, the Company reported that new downhole geophysical data has significantly extended the strike length of the high-grade feeder zone at Santa Barbara a further 250m along strike to the south-southeast from existing drilling. The 3D inverse magnetic model which correlates very strongly with the conductive zone suggested that the high-grade feeder zone may extend across the entire caldera for as much as a further 1 km along strike for a total potential strike length of at least 2 km. As reported, the definition drill program was modified to sectionally drill this potential extension with the intention of defining a major open pittable deposit in the valley of the caldera.

The Company completed 84,495m of drilling in 122 holes from the definition drill program in the Santa Barbara target area.

On November 22, 2022, Eloro announced the acquisition of the Mina Casiterita and Mina Hoyada properties covering 14.75 km² southwest and west of Iska Iska. These properties connect with the TUP-3 and TUP-6 claims previously staked by Eloro. Eloro has also staked additional land in the area. Following the acquisition, the total land package in the Iska Iska area to be controlled by Eloro will total 1,935 quadrants covering 483.75 km².

Artisanal mining in the 1960’s identified high grade tin (Sn) veins on the Mina Casiterita property that are hosted in an intrusive dacite. Production from 1962 to 1964 is reported by the Departamento Nacional de Geología in Bolivia to be 69.85 tonnes grading 50.60% Sn.

Recently completed magnetic surveys by Eloro has outlined an extensive, near surface, magnetic intrusive body on the Mina Casiterita property immediately southwest of Iska Iska. This intrusive hosts the previously mined high-grade tin veins and is very likely the continuation of the porphyry tin intrusion projected to be below the epithermal Ag-Sn-Zn-Pb mineralization at Iska Iska.

The Porco adit from which previously reported channel sampling returned 103m grading 521 g Ag eq/t (including g 117g Ag/t, 1.44 g Au/t, 0.54% Cu and 0.66% Sn) in altered basement sediments, is located near the northeast part of the magnetic anomaly, attesting to the potential strength and high-grade nature of the mineralized system in the area.

Drilling is planned in the Porco area and on Mina Casiterita commencing in early February 2023 with geological mapping, sampling and geophysical surveys now in progress on the full land package across the Iska Iska region.

Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce assay results from eight (8) additional diamond drill holes from its definition drilling program at the Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. Hole DHK-27 was drilled from Huayra Kasa due west at -45 degrees to a length of 860m to fill-in gaps in previous drilling of the High-Grade Zone. Five (5) additional holes (DHK-26. DHK-28, DHK-29, DHK-30 and DSB-42) were drilled to the southwest from the Huayra Kasa area to test the eastern margin of the Santa Barbara deposit. Hole DSB-43 was drilled on southwest side of Santa Barbara and hole DSB-46 tested the potential south-southeastern extension.

As previously reported in a press release dated November 27, 2022, the Company completed 84,495m of drilling in 122 holes to complete the definition drill program in the Santa Barbara target area, as shown in Figure 1. Tables 1 and 2 list significant assay results for the reported drill holes. Prices used for calculating Ag equivalent grades are as outlined in Eloro’s July 21, 2022 press release. Table 3 summarizes drill holes completed but with assays pending. The remaining eight (8) holes outstanding are in the south-southeastern extension area of the southern part of the Iska Iska caldera.

In addition to the new drill results, the Company is pleased to report on channel sampling results from the Mina 1 and Mina 2 underground workings located approximately 2km south-southeast of the Santa Barbara adit and approximately 800m east of the Porco adit where previously reported channel sampling returned a 103m strike length grading 521 g Ag eq/t (g 117g Ag/t, 1.44 g Au/t, 0.54% Cu and 0.66% Sn) in altered basement sediments (see Eloro’s November 17, 2021 press release). The location of Mina 1 and Mina 2 is shown in Figure 1. Complete channel sampling results are listed in Tables 4 and 5.

Tom Larsen, CEO of Eloro, said: “Hole DHK-27 when determining grade times intercept of 65,887 g Ag eq/t-m is the 2nd most valuable drill hole recorded to date and only just behind the 441-meter 66,389 g Ag eq/t-m intersection in hole DSB-30 reported last fall (see press release September 20, 2022). These are remarkable intercepts and grades. The significance of DHK-27 is the consistent high silver grades averaging 69.80 g Ag/t over a length of 325.48 meters which is close to true thickness. The higher grade 182.02 g Ag/t over 109.60 m portion of Hole DHK-27 attests to the potential of outlining much higher-grade areas in the Santa Barbara deposit with further drilling. It is also important to note that calculations for equivalent Ag grade in this release are based on July 2022 metal prices which for the major metals at Iska Iska are 13% to 33% lower than current prices hence the quoted values for silver equivalent are conservative.”

“The technical team under the supervision of Dr. Bill Pearson, P.Geo. and Dr. Osvaldo Arce, P.Geo. are setting up for resumption of diamond drilling in early February that will target the major tin porphyry that they believe is below the Iska Iska porphyry and extends into the newly acquired Mina Casiterita property,” continued Mr. Larsen. “Eloro has a remarkable opportunity to outline a second, potential world class tin deposit at Iska Iska in addition to the already extensive Santa Barbara silver-tin polymetallic deposit which is the focus of our inaugural mineral resource estimate expected by the end of Q1 2023. Expect to see a lot of activity in and around Iska Iska in 2023!”

Dr. Bill Pearson, P.Geo. Eloro’s Executive Vice President, Exploration commented: “We are working closely with Micon International to ensure that they have all the data necessary to complete the inaugural mineral resource estimate on the Santa Barbara deposit targeted for the end of Q1 2023. Blue Coast Research in Parksville, B.C. is completing their metallurgical studies and Gemin Associates in Lima, Peru is preparing preliminary economic parameters for the mineral resource estimation. On the ground, the Company has commenced induced polarization surveys on the Mina Casiterita property and is preparing for the restart of drilling in early February. The next phase of exploration drilling will target the potential tin porphyry in the Porco and Mina Casiterita areas. In addition, we have also initiated a program of geological mapping, sampling, and prospecting to evaluate the newly staked properties in the Iska Iska area which are detailed in our November 22, 2022 press release.”

Updated Geological Model for Iska Iska and its Santa Barbara Deposit

Drilling across the valley of the Iska Iska Caldera indicates that this area is underlain by a coarse-grained porphyritic dacitic intrusion that is well mineralized with Ag, Zn and Pb and is the likely source of the extensive epithermal mineralization in the Santa Barbara and Central Breccia areas. The porphyry, now named the Iska Iska Porphyry, is approximately 800m by 600m (Figure 1) and is notable for the absence of tin mineralization despite the abundance of tin in the nearby area. The tin at Iska Iska has been long recognized by Dr. Osvaldo Arce, P.Geo., an expert on Bolivian geology, as likely being the product of an earlier higher temperature and deeper tin porphyry, which has been overprinted by the later higher-level porphyry-epithermal Ag-Zn-Pb mineralization related to the Iska Iska porphyry.

Detailed analysis and modeling of the geological, geophysical, and geochemical data at Iska Iska indicates that the hydrothermal signature for the Iska Iska porphyry-epithermal system is approximately 2.8km along strike, up to 1.2km across strike and extending to a depth of at least 1.4km (Figure 1).

The High-Grade Zone that occurs within this extensive hydrothermal system defined by the >90 g Ag eq/t grade shell model is approximately 1,000m along strike, 800m wide and extends to a depth of 1,100m (Figure 2). This zone is open to the south, west and northwest as well as at depth. Magnetic inverse modelling and limited deep drilling suggest that the major tin porphyry is likely below the Iska Iska Porphyry and to the south and southwest in the Porco and Mina Casiterita areas.

The definition drilling program has more than doubled the potential volume of high grade mineralized material to be assessed for the mineral resource. Figure 2 shows the >90 g Ag eq/t grade shell model released September 20, 2022, compared to the date of this release. The success of the definition drilling in expanding the >90 g Ag eq/t zone is readily evident in Table 6, below and in Figure 2.

Table 6: Comparison of September 2022, >90 g Ag eq/t Grade Shell Model versus January 2023 Model for Santa Barbara Deposit

The overall mineralized zone as defined by the >30 g Ag eq/t grade shell has a strike length of 2,200m, a width of 1,200m and extends to a depth of at least 1,400m. Note that much of the drilling at Santa Barbara is at 100m spacing hence further drilling will likely provide better definition of higher-grade zones within the extensive mineralized envelope.

Santa Barbara Definition Drilling Huayra Kasa Area

Hole DHK-27 was drilled from Huayra Kasa due west at -45 degrees to a length of 860m. 50% of this hole returned reportable intersections averaging 172.09 g Ag eq/t. The silver grades in this hole are the highest and most extensive yet intersected in the Santa Barbara deposit.

Highlights from Hole DHK-27

• 202.43g Ag eq/t (69.80g Ag/t, 1.21% Zn, 0.49% Pb, and 0.12%Sn) over 325.48m from 93.30m to 418.78m, including a higher-grade portion of:
  • 395.98 g Ag eq/t (182.02g Ag/t, 1.73% Zn, 0.97% Pb, 0.18% Cu and 0.19%Sn) over 109.60m from 198.41m to 308.01m.

Five (5) additional holes (DHK-26. DHK-28, DHK-29, DHK-30 and DSB-42) were collared in the Huayra Kasa area to test the eastern margin of the Santa Barbara deposit. All these holes were drilled at an azimuth of 225⁰ with a dip of -60⁰. Collectively, these holes intersected many significant intersections within altered and mineralized dacite and dacitic breccia including:

Channel Sampling Mina 1 and Mina 2

Channel sampling of the Mina1 and Mina2 underground workings in the southern part of the property, approximately 2km south-southeast of the Santa Barbara adit, returned significant values from vein breccias as follows:

• 153.94g Ag eq/t (55.03g Ag/t, 0.11 g Au/t, 0.70% Zn, 0.16% Pb and 0.08% Sn) over 145.95m of the northwest trending drift, including a higher-grade portion of 285.16g Ag eq/t (120.18g Ag/t, 0.25 g Au/t 1.23% Zn, 0.30% Pb and 0.13% Sn) over 56.34m in Mina 1.
• 382.79g Ag eq/t (15.67g Ag/t, 1.70 g Au/t, 2.20% Zn and 0.75% Pb) over 68.53m in an east-west trending crosscut in Mina 2. A second shorter crosscut on a secondary subparallel structure approximately 20m to the south returned 475.78g Ag eq/t (69.31g Ag/t, 0.26 g Au/t, 5.62% Zn and 1.92% Pb) over 26.67m in Mina 2.

Figure 3 is a plan map showing sampling results at Mina 1 and Mina 2. Table 6 gives details of the sampling results.

These results, along with the previously reported channel sample results from Porco noted above, clearly indicate that the Iska Iska mineralizing system extends much further south outside of the principal Iska Iska Caldera. Based on field work by the Eloro geological team, it appears that there may be a second, larger ringer structure with a diameter of approximately 4.6km outside the main Iska Iska caldera that could be another major focus of mineralization. This possibility is currently being explored by geological mapping and geophysical surveys to outline targets for drill-testing in conjunction with work in the Porco area and the nearby Mina Casiterita property.
