Antilles (ASX:AAU) open up El Pilar

Antilles Gold has returned more encouraging results for proposed open pit mining operations on the gold-copper oxide deposit at its El Pilar Project in Central Cuba.

Assays came in for the first seven of 17-holes from its ongoing campaign, showing more gold-copper returns from a 7000-metre program directed at validating historic results and establishing a Mineral Resource Estimate for the proposed Nueva Sabana mine.

A relatively small open pit operation at low capital expenditure could provide early cash flow to El Pilar, mining from well-defined gold zones and copper areas which continue to increase both laterally and vertically.

“Based on drilling and metallurgical test work results to date, it appears probable that a low cap-ex mine could be developed on the El Pilar oxide deposit to exploit the gold and copper domains to a depth of around 80m to 100m in advance of any development of the underlying copper-gold porphyry system. An initial drilling program on the porphyry intrusive has commenced,” Antilles Executive Chairman Brian Johnson said.

Gold results

• PDH-007 – 7m at 5.27g/t Au from 1m, including 3m at 10.87g/t Au
• PDH-009 – 24m at 1.48g/t Au from 2m
• PDH-011 – 2m at 6.09g/t Au from 30m, 3m at 3.94g/t Au from 64m, 1m at 7.91g/t Au from 75m
• PDH-012 – 16m at 6.30g/t Au from 2m including 4m at 11.75g/t and 2m at 14.02g/t
• PDH-013- 6m at 2.07g/t Au from 5m including 1m at 7.41g/t Au

Copper results

• PDH-007 – 25m at 0.57% Cu from 36m
• PDH-008 – 24m at 0.71% Cu from 44m including 10m at 1.4% Cu
• PDH-010 – 27m at 0.73% Cu from 43m
• PDH-012 – 11m at 0.49% Cu from 52m, 19m at 0.8% Cu from 109m including 2m at 5.2% Cu
• PDH-013 – 22m at 1.1%Cu from 44m including 5m at 2.2% Cu

Metallurgy

While testing on recoveries from the underlying copper domain is continuing, work on ore from the upper gold domain has indicated a recovery of 85 per cent from a simple rougher flotation circuit, producing at a grade of 53.1g/t with a head grade of 2.11g/t.

But the near-term project of Antilles’ joint venture company with state-owned GeoMinera is the proposed development of the La Demajagua open pit mine on the Isle of Youth in the nation’s southwest, where metallurgy and geochemical modelling has spurred plans for production of concentrates including gold, silver, and antimony.

Long-term plans

The joint venture expects profits from La Demajagua, seeing an open pit mine funding future mining operations and extensive exploration over major targets, with Antilles positioned at the forefront of an emerging Cuban mining sector as the island nation opens its industry to foreign investment.
