Santa Barbara Breccia Pipe Shows Promise At Iska Iska Silver-Tin Polymetallic Project In Bolivia
Eloro Resources Ltd. (TSXV: ELO) (OTCQX: ELRRF) has identified a promising silver zone at its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia.
To date, the company has completed 58 diamond drill holes totalling 26,982m to test major target areas at Iska Iska.
The latest drilling results from four additional holes tested the mineralised envelope of the Santa Barbara Breccia Pipe (SBBP) (Holes DDHK-19 and DHK-20) and the central-southern part of the Central Breccia Pipe (CBP) (Holes DCN-04 and DCS-02).
To date, every drill hole that has been assayed has returned multiple reportable mineralised intercepts. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are completing drilling at SBBP in order to outline an initial compliant resource.
A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of SBBP and its mineralized envelope.
Drilling highlights include:
- Hole DHK-20, drilled from the west end of the Huayra Kasa underground workings at -50 degrees on section with hole DHK-18, which intersected 129.65 g Ag eq/t over 300.75m (see press release dated July 28, 2021), returned 234.19 g Ag eq/t (70.5 g Ag/t, 2.31% Zn, 2.74% Pb and 0.04% Sn) over 53.20m from 139.35m to 192.55m including a higher grade portion of 931.73 g Ag eq/t (367.29 g Ag/t, 5.64% Zn, 13.67% Pb and 0.10% Sn) over 9.26m. Multiple additional significant mineralized intervals occur above and below this intercept. Mineralization occurs within the mineralized envelope east of SBBP in all host rock types.
- Hole DHK-19, drilled to the southeast at -45 degrees from the west end of the Huayra Kasa underground workings, intersected 108.24 g Ag eq/t (3.14g Ag/t, 0.24 g Au/t, 2.02% Zn and 0.58% Pb) over 48.2m from 46.95m to 95.15m in altered dacite in the mineralized envelope of the SBBP. This includes a higher-grade interval grading 180.76 g Ag eq/t (4.46 g Ag/t, 0.35 g Au/t, 3.58% Zn and 1.04% Pb) over 15.02m. Multiple additional significant mineralized intervals occur above and below this intercept.
- Hole DCN-04 was drilled at -80 degrees to the north from the northern radial platform of the CBP. This hole intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and .19% Sn) over 62.01m from 281.40m to 343.41m; 134.33 g Ag eq/t (70.42 g Ag/t and 0.16% Sn) over 22.59m from 417.05m to 439.64m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m from 659.55m to 677.00.m
- Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.75 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m. Mineralization in the southern part of the CBP is notable for containing significant Zn and Pb as well as Ag and Sn, a metal assemblage more comparable to SBBP and Porco. The northern part of the CBP is dominantly Sn-Ag suggesting a deeper origin for this part of the breccia pipe.
Major Potential Extension to Santa Barbara Breccia Pipe
Data from a ground magnetics survey conducted by Eloro outlined a prominent area of anomalously low magnetic variability northwest of the SBBP, likely reflecting strong hydrothermal alteration.
Subsequent 3D inversion modelling confirmed that this area warranted drill testing as this pattern is comparable to the SBBP and CBP, both marked by similar magnetic anomalies. Recently completed holes DSB-12 drilled southeast at -40 degrees and DSB-13 on section at -65 degrees intersected strongly altered dacite and breccia with widespread mineralisation. \
“The company is pleased to report that the Santa Barbara Breccia Pipe and its surrounding mineralised envelope is in fact much larger than initially envisioned,” CEO Tom Larsen said.
“Our drilling campaign is now focused within this extensive area in order to define an inaugural NI 43-101 compliant mineral resource which we expect to have completed in Q1 2022.
“In addition, I am pleased to announce that, as a result of the continuing sampling backlog delays at the ALS Laboratory in Lima due to Covid-19 induced issues, the Company has recently commissioned Alfred H Knight (AHK) Laboratories of Great Britain along with ALS Laboratories to help alleviate this backlog. AHK is highly recognised, having a global network of accredited laboratories with operations in over 35 countries. They have recently opened facilities in Bolivia, due to the high demand taking place from mining companies in the region.
“This is a significant development which will improve the reporting of drilling results at Iska Iska going forward.” For further information please visit: https://www.elororesources.com/
