All five underground drill-holes (BUUY126, BUUY130, BUUY134, BUUY138 and BUUY142) and a more deeply-drilled, surface-collared hole (BUSY349) in central Veta Sur were successful in infilling the deposit, extending existing veins and encountering new veins outside of the current mineral resource envelope.
BUUY126 laterally extended a broad high-grade subzone at relatively high elevations (from elevation of 1,611 metres) with an intercept of:
-- 28.4 metres @ 20.5 g/t gold and 135 g/t silver, including 1.35 metres @ 82.1 g/t gold and 54 g/t silver, plus 2.15m @ 135.3 g/t gold and 921 g/t silver plus 1.9 metres @ 33.4 g/t gold and 527 g/t silver.
BUUY126 also vertically extended a separate high-grade subzone at lower elevation (from elevation of 1,531 metres), with a broad intercept of:
-- 10.9 metres @ 10.8 g/t gold and 85 g/t silver, including 1 metre @ 97.4 g/t gold and 510 g/t silver.
Both high-grade subzones remain open vertically and exhibit visible gold-bearing Stage II style mineralization.
Several drill-holes aimed at infilling the central Veta Sur system intersected vein domains with significantly higher grades and/or thicknesses than in the current mineral resource model. Such intercepts, at moderate elevations in BUSY349, include:
-- 3.9 metres @ 10.1 g/t gold and 35 g/t silver (elevation of 1,432 metres); and-- 3 metres @ 86.8 g/t gold and 26 g/t silver (elevation of 1,420 metres; among the deeper occurrences of Stage II, visible gold-bearing mineralization).
In other drill-holes, higher in the Veta Sur system, intercepts include:
-- 5.75 metres @ 9.7/t gold and 71 g/t silver, including 1.3 metres @ 29 g/t gold and 127 g/t silver (BUUY138, elevation of 1,693 metres); and-- 7.25 metres @ 9.1 g/t gold and 72 g/t silver, including 1.6 metres @ 31.1 g/t gold and 262 g/t silver (BUUY142, elevation of 1,675 metres).
All drill-holes intersected vein domains outside of the current Veta Sur mineral resource envelope. Significant intercepts, extending vein domains to higher elevations, include:
-- 0.65 metres @ 41.5 g/t gold and 18 g/t silver (BUUY126, elevation of 1,671 metres); and-- 2.25 metres @ 40.8 g/t gold and 48 g/t silver, including 1.05 metres @ 86 g/t gold and 95 g/t silver (BUUY138, elevation of 1,701 metres).
Intersections in all drill-holes to the north of the current mineral resource envelope (Figure 1) exhibit relatively high silver/gold and some high-grade silver. Significant intercepts in these as-yet unmodelled vein domains include:
-- 0.5 metres @ 2.7 g/t gold and 634 g/t silver (BUUY130, elevation of 1,730 metres);-- 0.50 metres @ 0.7 g/t gold and 369 g/t silver (BUUY138, elevation of 1,638 metres);-- 2.8 metres @ 4 g/t gold and 480 g/t silver (BUUY142, elevation of 1,564 metres); and-- 2.85 metres @ 1.1 g/t gold and 341 g/t silver (BUUY142, elevation of 1,517 metres).
BUSY343, drilled to the north from the La Estera area (Figure 1), encountered multiple mineralized intervals at deep elevations (Figure 2). Significant intercepts, over a vertical range of 170 metres, include:
-- 0.58 metres @ 35.1 g/t gold and 36 g/t silver (elevation of 576 metres);-- 0.52 metres @ 20.9 g/t gold and 12 g/t silver (elevation of 570 metres);-- 2.66 metres @ 5.3 g/t gold and 19 g/t silver, including 1.13 metres @ 11.0 g/t gold and 40 g/t silver (elevation of 506 metres); and-- 0.65 metres @ 14.1 g/t gold and 3 g/t silver (elevation of 409 metres).
