In the El Huabo sector, hole 16 tested the southwestern end of the mineralized zone hosting the Los Socavones epithermal gold-silver deposit. Preliminary work in this sector identified a gold-in-soil anomaly, an induced-polarization anomaly, and the presence of epithermal-type, low-sulphidation mineralization.
Hole 16 intersected 32.5 metres (from 167.45 metres) grading 0.6 gram gold and 2.1 grams silver per tonne plus 0.09% zinc, including 3.35 metres of 2.1 grams gold, 9.9 grams silver and 0.62% zinc. Mineralization is associated with hematized and chloritized fault zones characterized by intense brecciation and a stockwork of quartz-calcite-pyrite-sphalerite veinlets in volcanic rocks.
Sulliden says this hole shows that the gold-bearing structure continues for at least 2 km and remains open to the southwest.
Hole 20 tested a well-defined gold-in-soil anomaly on the edge of the Cementerio copper-gold porphyry system. This hole intersected alternating epidotized and carbonatized massive diorite, as well as strongly sericitized and argilitized brecciated diorite.
The complete 287-metre length of hole 20 returned 0.16 gram gold, 2.3 grams silver, 0.06% copper and 0.13% zinc, including a 25.7-metre section of 0.4 gram gold, 4.1 grams silver, 0.16% copper and 0.19% zinc.
Five other holes have been completed in the San Antonio sector, where porphyry copper-gold mineralization was discovered last year. Results are to be released soon.
