Eloro Resources Ltd. Announces Assay Results from Eight Additional Diamond Drill Holes from Its Definition Drilling Program At the Iska Iska Silver-Tin Polymetallic Project
Eloro Resources Ltd. announced 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. In addition to the new drill results, the company reported 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. 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 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. TheHigh-Grade Zonethat 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. 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. shows the >90 g Ag eq/t grade shell model released September 20, 2022, compared to the date of this release. 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.
