TORONTO, Oct. 18, 2022 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce assay results from two (2) additional diamond drill holes from its on-going drilling program at the Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. One drill hole, DSB-36, collared 400m southeast of the Santa Barbara adit, tested the extension of the core of the high-grade feeder zone at Santa Barbara while hole DSB-34, tested the potential southwest limits of the high-grade feeder zone as shown in Figure 1.
To-date, the Company has completed 79,258m in 118 drill holes to-date at Iska Iska, including four holes in progress, as shown in Figure 1. Table 1 lists 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 2 summarizes drill holes completed with assays pending and holes in progress.
Tom Larsen, CEO of Eloro, said: “Results from hole DSB-36 continue to confirm that the high-grade feeder zone extends much further south-southeast across the valley of the Iska Iska caldera as interpreted from our geophysical surveys. This new hole has extended the strike length a further 400m to the south-southeast where it remains open along strike. We are continuing to aggressively drill this important target which has the potential to outline a significant open pittable resource.”
Dr. Bill Pearson, P.Geo. Eloro’s Executive Vice President, Exploration commented: “We are continuing to carry out our 100m-spaced sectional drilling across the Iska Iska caldera valley. As shown in Figure 2, we have four holes in progress with four additional holes planned that collectively total 6,000m to complete our first-pass definition drill program. We expect that this drilling will be completed by the mid- to latter part of November. Currently, assays are outstanding for approximately 14,213m of drill core as shown in Table 2. Turnaround from our assay laboratories has however improved in recent weeks so we expect most of this backlog to be cleared up by the end of November. We are working closely with Micon International to build a robust model for the mineral resource estimation. GeologicAI is also completing development of comprehensive mineral maps calibrated by our new mineralogical data which will greatly aid the modelling process.”
Santa Barbara High Grade Feeder Zone Extension Definition Drilling
Hole DSB-36 was drilled to test the potential south-southeastern extension of the Santa Barbara High Grade Feeder Zone shown in Figure 1.

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 | |

| 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 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 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, 0.078g 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.
