Antilles buoyed by initial El Pilar diamond drilling

Antilles Gold has struck mineralisation in the first two diamond drill holes sunk into its El Pilar copper-gold porphyry intrusive in central Cuba and believes the two intersections are “highly encouraging”.

The porphyry intrusive is one of three clusters recently identified from geophysical and induced polarisation (IP) surveys undertaken at the company’s El Pilar, Gaspar and Camilo targets. The targets were refined following 3D modelling and interpretation of its surveys completed across a 700-hectare area at El Pilar.

It has enabled management to etch out a cluster of highly-prospective copper-gold mineralised porphyries along a 1350m strike length, spearheaded by big intrusive bodies at El Pilar, Gaspar and Camilo.

The El Pilar porphyry body is interpreted to extend through a 300m strike and a 200m width. At the nearby Gaspar target, the porphyry has been outlined over a 200m strike and up to a 200m width.

The first hole from the latest drilling hit a 200m porphyry halo and 226m into the porphyry zone below to end in mineralisation at a depth of 425.5m. A second hole has also been drilled into the halo at 296m and shows similar mineralisation to the first.

The company says the interpreted early mineralisation in both holes indicates drilling is near the core of the porphyry system, where potentially economic and large copper-gold porphyry deposits can be located.

Results from the initial 6 drill holes will determine the scope of next year’s program which could be extended to the Gaspar and Camillo intrusives, with the aim of establishing a significant copper mining target. Antilles Gold executive chairman Brian Johnson

The company says its El Pilar and Gaspar porphyry targets, which are adjacent to previous shallow drilling of the greater El Pilar copper-gold system, have been interpreted as having “significant dimensions”.

The El Pilar project covers 1700ha and is one of three exploration concessions held by Antilles in an agreement with the Cuban government-owned, GeoMinera SA.

A solitary deep diamond hole drilled into the outer zone of the El Pilar porphyry returned a whopping 134m averaging 1.23 per cent copper from a depth of just 49m downhole, including 18.5m coming in at 4.85 per cent copper and 14m averaging 38.31 grams per tonne gold, with mineralisation remaining open at depth.

Antilles says the initial results of the latest drill campaign vindicates the recent geophysical modelling, with copper-gold mineralisation indicated over large widths vertically below the known oxide domains.

Assays for the two diamond drill holes are expected next month while a third hole will test a high-intensity IP zone on the eastern side of El Pilar.
