Eloro Resources Ltd. (TSXV: ELO) has identified the longest continuously mineralised intersection obtained in drilling thus far in assay results from 21 diamond drill holes from its on-going drilling programme at the Iska Iska silver-tin polymetallic project 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.
Overall, the company has completed 74,782m in 113 drill holes to-date at Iska Iska, including five holes in progress.
“These results, combined with the enhanced geological and geophysical interpretation, show the continuing expansion of the already extensive Iska Iska high-grade mineralised system, which has a potential strike length of at least two km,” CEO, Tom Larsen, said.
“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.”
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, as described below. The conductivity data from boreholes have extended the high-grade feeder zone a further 250m along strike to the south-southeast.
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 one km along strike.
The definition drill programme 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.
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 -60° 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
- Hole DSB-32, drilled on-section at -60° to the southeast of hole DSB-30 intersected 185.94 g Ag eq/t (44.55 g Ag/t, 0.57% Pb, 0.14% Cu and 0.25% Sn) over 135.15m from 0.00 to 135.15m, including a higher-grade section of 277.34 g Ag eq/t (78.12 g Ag/t, 0.09 g Au/t, 1.01% Pb, 0.27% Cu and 0.33% Sn) over 66.04m from 45.13m to 111.17m.
- Hole DSB-29, collared at surface to test the southeast extension of the high-grade feeder system, was drilled to the SW at -60° and intersected multiple intersections including:
- 108.31 g Ag/t (14.31 g Ag/t, 0.08 g Au/t, 0.81% Zn, 0.40% Pb and 0.08% Sn) over 110.40m from 320.94 to 431.34m, including a higher-grade portion of 174.81 g Ag/t (18.66 g Ag/t, 0.17 g Au/t, 1.43% Zn and 0.88% Pb) over 36.06m from 334.66m to 370.72m
- Hole DSB-28, located approximately 100m northwest of DSB-29, collared at surface to test the high-grade feeder system, was drilled to the SW at -60° and intersected multiple intersections including:
- 98.98 g Ag/t (4.41 g Ag/t, 1.16% Zn and 0.49% Pb) over 96.51m from 39.49 to 136.00m, including a higher-grade portion of 220.47 g Ag/t (2.99 g Ag/t, 2.68% Zn, 1.13% Pb and 0.11% Sn) over 16.52m from 74.20m to 90.72m,
- 94.39 g Ag eq/t (5.49 g Ag/t, 1.36% Zn and 0.31% Pb) over 90.18m from 163.17m to 253.35m, and
- 83.44 g Ag eq/t (31.12 g Ag/t, 0.10 g Au/t, 0.27% Zn and 0.23%Pb) over 86.32m from 455.52m to 541.84m including higher-grade portions of 278.75 g Ag eq/t (56.42 g Ag/t, 0.23 g Au/t, 0.83% Zn, 2.38% Pb and 0.22 Sn) over 6.06m from 458.57 to 464.63m and 197.15 g Ag eq/t (136.45 g Ag/t, 0.22 g Au/t, 0.39% Zn, 0.11% Pb and 0.04 Sn) over 10.59m from 520.85 to 531.44m.
- Overall, 55% of the overall length of this 831.80m long hole yielded reportable intersections, which collectively average 83.69 g Ag eq/t.
