Eloro drills 441.2 m of 150.47 g/t AgEq at Iska

2022-09-20 11:18 ET - News Release

Mr. Tom Larsen reports

ELORO RESOURCES INTERSECTS 150.47 G AG EQ/T (9.45 G AG/T, 1.53% ZN, 0.88% PB AND 0.07% SN) OVER 441.21M IN HIGH-GRADE FEEDER ZONE IN SANTA BARBARA TARGET AREA AT THE ISKA ISKA SILVER-TIN POLYMETALLIC PROJECT, POTOSI DEPARTMENT, BOLIVIA

Eloro Resources Ltd. has released assay results from 21 diamond drill holes from its continuing drilling program at the Iska Iska silver-tin polymetallic project in the Potosi department, southern Bolivia. Five surface holes (DSB-28 to DSB-30, DSB-32 and DHK-25) tested the high-grade feeder zone in Santa Barbara which was also tested by two underground holes (DSBU-09 and DSBU-011). Six holes (DSB-16 to DSB-19, DSB-23 and DSB-27) tested the northwest extension of Santa Barbara. Eight holes (DPC-04 to DPC-08 and DPC-10 to DPC-12) are reported for the Porco area. Five surface drills are focused on completing drilling in the Santa Barbara resource definition drilling area and its extension to the south-southeast. This press release also outlines a major update on the geophysical surveys which have greatly expanded the higher-grade feeder area target zone to the south-southeast.

Over all, the company has completed 74,782 metres (m) in 113 drill holes to date at Iska Iska, including five holes in progress. The attached tables list significant assay results for the drill holes reported. Prices used for calculating silver equivalent (AgEq) grades are as outlined in the July 18, 2022, press release. An attached table summarizes drill holes with assays pending. Highlights for each major target area are as follows.

Santa Barbara high-grade feeder zone definition drilling.

Drilling continues to expand the extent of the high-grade feeder zone at Santa Barbara, especially to the south-southeast. New borehole geophysical data have significantly expanded the strike length of this important high-grade zone. The highly conductive zones correlate very well with previously released high-grade drill intersections. The conductivity data from boreholes have extended the high-grade feeder zone a farther 250 m along strike to the south-southeast. The 3-D (three-dimensional) 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 farther one kilometre (km) along strike. The definition drill program has now been modified to sectionally drill this highly prospective extension, with the intention of defining a major open-pittable mineral resource in the valley of the caldera.

Tom Larsen, chief executive officer of Eloro, said: "The results presented in this press release, combined with the enhanced geological and geophysical interpretation, show the continuing expansion of the already extensive Iska Iska high-grade mineralized system, which has a potential strike length of at least two km. The new data demonstrate excellent potential to outline a major open-pittable deposit in the valley of the Iska Iska caldera. As a result, the estimated completion date for the maiden NI 43-101 mineral resource has been pushed back to the end of Q1 2023 to provide additional time to drill test this important target. We thank both ALS and AHK laboratories for greatly reducing our backlog of samples over the last several months, enabling us to report the results from a large number of holes in this release."

Dr. Bill Pearson, PGeo, Eloro's executive vice-president of exploration, commented: "We are continuing our definition diamond drill program with five surface rigs focusing on the south-southeastern extension of the high-grade feeder zone. As each drill hole is completed, we survey the hole using a pole-dipole IP [induced polarization] array down the hole, as well as cross hole measurements using current in surrounding holes. Our borehole IP team from McKeown Exploration Services, which is supervised by our chief geophysicist, Dr. Chris Hale, PGeo, works closely with our drill contractor, Leduc Drilling, to allow holes to a 1,000-metre depth to be surveyed efficiently. This has greatly enhanced our geophysical program and has led to the tremendous geophysical model disclosed in this press release. We continue to get numerous and extensive mineralized intersections in all our holes as outlined below. In addition, we now know that the DPC series of holes in the Porco area are mainly just on the edge of the massive conductive zone and magnetic susceptibility high that goes through the Porco area at a deeper level."

Significant results from five additional surface drill holes and two underground holes testing the high-grade feeder zone at Santa Barbara are as follows:

Hole DSB-30, drilled to the SW at -60degree across the centre of the current high grade feeder zone, intersected 150.47 g Ag eq/t (9.45 g Ag/t, 1.53% Zn and 0.88% Pb) over 441.21m from 28.70m to 469.91m, including a higher-grade portion grading 209.30 g Ag eq/t (10.06 g Ag/t, 2.76% Zn and 0.98% Pb) over 102.30m from 80.05m to 182.35m. This is the longest continuous mineralized intersection obtained in drilling at Iska Iska thus far.

Overall, 67% of this 909.85m long hole contains reportable intersections which collectively average 133.49 g Ag eq/t

Major Extension of Santa Barbara High Grade Feeder Zone.

As noted above, new borehole geophysical data have significantly expanded the strike length of the important high-grade feeder zone at Santa Barbara. The highly conductive zones correlate very well with previously released high grade drill intersections. Figure 2 is a NW-SE longitudinal section showing the geophysical results in the Santa Barbara high grade feeder zone. Based on current data, this feeder zone has a potential overall strike length of at least 2km. Figure 3 is a view looking south across the Iska Iska caldera valley and Figure 4 shows the conductivity model in the same view as Figure 3.

Eloro's Chief Geophysicist, Dr. Chris Hale, P.Geo. commented: "The geophysical measurements of the most recent boreholes have contributed to a clear picture extending the mineralization south-southeastwards from the mineralization reported in Eloro's July 18, 2022 press release. Where we have borehole IP and conductivity data a conductive core of mineralization extends to the south-southeast for 250m. This conductive core is contained within a broad volume of elevated chargeability that reflects disseminated mineralization. The geophysical correlation is open at depth and to the east where it is only limited by the distribution of drill holes for the borehole IP measurements. A strong correlation of mineralization with both conductivity and magnetic susceptibility extends toward the south-southeast and likely continues for a further kilometer or more at depth where the magnetic susceptibility model indicates an extension but where we do not yet have any conductivity data other than for DPC-08 and DPC-09. Conductivity data for DPC-09 show that this south-directed hole is tangential to a strong off-hole conductivity just to the west. This conductivity anomaly merges with the magnetic susceptibility model showing that the Santa Barbara high grade feeder zone extends deep beneath the known Porco mineralization."

Reinterpretation and Significance of Drilling in the Porco Area.

Results for eight (8) diamond drill holes that tested the magnetic susceptibility anomaly in the Porco area are summarized in Table 2. Locations of these holes are shown on Figure 1. Holes DPC-04, DPC-05 and DPC-06 were drilled from the Porco radial drill platform. Hole DPC-07 was drilled at an azimuth of 235degree at -60degree across the gap area between the Porco and Central Breccia pipes. Holes DPC-08 (Az 235degree, -65degree), DPC-10 (Az 225degree, -70degree) and DPC-11-12 (both Az 235degree, -70degree) were drilled from the access road to the Porco radial platform. Results from DPC-09 (Az 180degree, -75degree) were previously released on June 14, 2022. Highlights are as follows:

Hole DPC-10 returned 38 reportable intersections including 268.41 g Ag eq/t (30.31 g Ag/t, 2.22% Zn, 1.19% Pb and 0.16% Sn) over 17.88m from 253.77 to 271.65m and 185.50 g Ag eq/t (4.18 g Ag/t, 1.15% Zn, 0.92% Pb and 0.17% Sn) over 5.98m from 193.65 to 199.63m.

140.31 g Ag eq/t (9.07 g Ag/t, 2.14% Zn and 0.61% Pb) over 3.03m from 149.20m to 152.23m,

134.34 g Ag eq/t (6.40 g Ag/t, 2.27% Zn and 0.33% Pb) over 4.56m from 237.84m to 242.40m, and

125.58 g Ag eq/t (5.55 g Ag/t, 0.29 g Au/t, 1.15% Zn and 0.13% Pb) over 9.02m from 443.40m to 452.42m.

Hole DPC-07 returned 13 reportable intersections including 286.53 g Ag eq/t (59.08 g Ag/t, 0.37 g Au/t, 1.80% Zn, 0.14% Pb 0.19% Cu and 0.20% Sn) over 3.00m from 587.12 to 590.12m and 158.27 g Ag eq/t (10.41 g Ag/t, 2.51% Zn and 0.09% Pb) over 4.51m from 681.95 to 686.46m.

Hole DPC-06 in the radial drill platform returned 11 reportable intersections including:

122.34 g Ag eq/t (4.66 g Ag/t, 2.16% Zn and 0.16% Pb) over 16.43m from 156.01m to 172.44m,

277.57 g Ag eq/t (50.31 g Ag/t, 3.44% Zn and 1.41% Pb) over 6.03m from 133.55 to 139.58m, and

447.07 g Ag eq/t (4.10 g Ag/t, 0.91% Zn and 3.37% Pb) over 4.41m from 248.95 to 253.36m.

All the Porco holes reported in this release are on the margins of the conductive/magnetic anomalies, hence the presence of widespread higher-grade mineralization on the edge of these anomalies is very encouraging. Further drilling will be carried out to test the core of the geophysical anomalies in these areas.

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.

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 (29.53 g 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 a target zone 1400m along strike, 500m wide and that extends to a depth of 600m. This zone is open along strike to the northwest and southeast as well as to the southwest. The Company's nearer term objective is to outline a maiden NI 43-101 compliant mineral resource within this large target area. As outlined in this press release as a result of continuing discoveries from recent drilling that have substantially extended the high-grade feeder zone at Santa Barbara, the Company has pushed back the inaugural mineral resource to the end of Q1 2023.
