De Grey Mining‘s (ASX: DEG) drilling program at the Vein Breccia Zone of its Sierra Morena project in Argentina has intersected a mineralised polymetallic epithermal system with gold, silver and base metals in three out of four holes.
The results indicate that not only has the company encountered better mineralisation the deeper it drills, it is also encountering consistent gold and silver mineralisation.
One of the holes intersected multiple zones of mineralisation of:
- 4.3 metres at 0.4 grams per tonne gold, 21.8 g/t silver, 0.1% zinc and 0.3% lead from 82.3 metres;
- 2.5 metres at 1.35g/t gold, 25g/t silver, 0.1% zinc and 0.2% lead from 155.3 metres including 1 metre at 3.7g/t gold and 50g/t silver; and
- 2 metres at 0.4g/t gold, 106.5g/t silver, 0.3% zinc and 0.6% lead from 205.9 metres including 1 metre at 0.6g/t gold, 164g/t silver, 0.6% zinc and 1.2% lead.
These results when layered on the 3D CSAMT model show that sulphide mineralisation in the core correlates with the edge of the CSAMT target.
The base metal grades indicate the drilling is in a polymetallic vein breccia and the silver and gold grades give rise to the possibility of greater mineralization within this now defined system.
De Grey’s next program planned for the Vein Breccia Zone will test the extensions of the polymetallic epithermal mineralisation intercepted in the recently completed drill holes.
Sierra Morena is located within the western Deseado Massif and is located about 25 kilometres west of Patagonia Gold’s El Tranquilo project, which has combined resources of about 902,000 ounces of gold and 29 million ounces of silver.
