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
Dimension | September 2022 Model | January 2023 Model | Increase (m) | % Increase | |
Strike | 700m | 1,000m | 300m | 42 | % |
Width | 650m | 800m | 150m | 23 | % |
Depth | 810m | 1,100m | 290m | 36 | % |
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.

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.

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.

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):
Element | Price $US (per kg) | Ratio to Ag | |
Ag | $607.00 | 1.0000 | |
Sn | $23.55 | 0.0589 | |
Zn | $2.98 | 0.0046 | |
Pb | $1.92 | 0.0032 | |
Au | $54,932.80 | 79.7221 | |
Cu | $7.00 | 0.0134 | |
Bi | $12.76 | 0.0177 | |
Cd | $5.50 | 0.0076 |
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 Ltd. to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. 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.

Qualified Person
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, has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience, including extensive work in South America, manages the overall technical program, working closely with Dr. Osvaldo Arce, P.Geo. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P.Geo., FAusIMM of Micon are regularly consulted on technical aspects of the project.
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 (29.53g Ag/t, 0.078 g 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. As a result, the estimated completion date for the maiden National Instrument 43-101 mineral resource was pushed back to the end of Q1 2023.
The Company completed 84,495m of drilling in 122 holes from the definition drill program in the Santa Barbara target area, as previously announced on November 27, 2022.
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.
