ELORO RESOURCES INTERSECTS MULTIPLE INTERSECTIONS INCLUDING 122.25G AG EQ/T (17.77G AG/T, 0.30% ZN, 0.33% PB, 0.10% CU AND 0.16% SN) OVER 210.74M IN HIGH GRADE FEEDER ZONE, SANTA BARBARA TARGET AREA AT THE ISKA ISKA SILVER-TIN POLYMETALLIC PROJECT
Eloro Resources Ltd. has released assay results from eight additional diamond drill holes from its continuing drilling program at the Iska Iska silver-tin polymetallic project in the Potosi department, southern Bolivia. Six of these holes (DSB-35 and DSB-37 to DSB-41) tested the south-southeastern extension of the high-grade feeder zone at Santa Barbara while METSBUG-03 is a metallurgical hole drilled from the Santa Barbara adit underground drill bay. Hole DM2-01 is a reconnaissance drill hole near the Mina 2 adit in the southeast part of the property.
To-date, the Company has completed 84,495m in 122 drill holes at Iska Iska which completes the definition drill program in the Santa Barbara target area as shown in Figure 1. Tables 1, 2, 3, 4 and 5 list significant assay results for the drill holes reported. Prices used for calculating Ag equivalent grades are as outlined in Eloro's July 21, 2022 press release. Table 6 summarizes drill holes completed with assays pending.
Tom Larsen, CEO of Eloro, said: "Now that the reconnaissance drill holes just released, DSB-38, -39 and -40, are adding a further 500 meters of mineralized strike length, these latest results should add substantial tonnage to our resource model. Infill drilling at a later date should further upgrade and expand the higher metal value zonations that have become characteristic of the Iska Iska system."
"Given the guidance of our geophysics, if one were to draw a line from Huayra Kasa in the north of the Iska Iska Caldera southwest to Mina Casiterita one can reasonably assume up to a 3 kilometre potential strike length of mineralization given the magnetic data to date," added Mr. Larsen. "The current strike length, width and depth of the Santa Barbara complex, which is still open in all directions, is pointing to the strong possibility that Iska Iska will become a giant "bonanza style" Bolivian polymetallic discovery."
Dr. Bill Pearson, P.Geo. Eloro's Executive Vice President, Exploration commented: "We continue to obtain promising results from our drilling on the High-Grade Feeder Zone at Santa Barbara. The on-strike extension of this zone to the south-southeast is now confirmed for an additional 500m for a total strike length of 1,500m. Geophysical data indicates potential for a further 500m strike length to 2,000m which has been initially tested by the final drill holes in our 2022 program for which results are pending. The width of the Santa Barbara mineralized zone is now up to 1,000m across strike with a depth of at least 800m. The mineralized zone remains open in ALL directions as well as at depth. With completion of our planned drilling program, we are now focussed on working with Micon International to complete the inaugural mineral resource estimate."
Santa Barbara High Grade Feeder Zone Extension Definition Drilling
Six holes (DSB-35, DSB-37 to DSB-41) tested the south-southeastern extension of the high-grade feeder zone at Santa Barbara.

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 99% 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 Potosi 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, 0.078g 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 suggests 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 has been 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 has been pushed back to the end of Q1 2023.
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 Geologia 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.
