Geology & Mineralisation of La Cristina Copper-Gold Prospect - Sierra Maestra Copper Belt, Cuba

Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX: AAU, OTCQB: ANTMF) advises it has received the attached Report on the Geology and Mineralisation of the La Cristina copper-gold prospect within the Sierra Maestra copper belt in south east Cuba. The La Cristina concession is held in an Exploration Agreement as are two other concessions in the same region with the three properties totalling 53,710ha.

The Report was prepared by the Company’s Exploration Director, Dr Christian Grainger, and Colombian consulting geologist, Riccardo Sierra, and summarises the results of prospecting activities carried out between July and November 2023.

Conclusions and Recommendations

• The La Cristina project represents an excellent exploration project with high potential for the discovery of both porphyry copper-gold and high-sulphidation gold-copper deposits.
• A major E-W structural corridor has been located between the Borbon and Arabica prospects that measures 4.5 km x 2.2 km. This zone incorporates overlapping pervasive and intense zones of both advanced argillic and phyllic style hydrothermal alteration styles that indicates the presence of a potentially large porphyry system at depth that has a large exposed lithocap and high- sulphidation style halo over very large dimensions at surface.
• Numerous zones of high-grade copper-gold mineralization has been identified from initial sampling in numerous historical artisanal underground workings and their immediate vicinities. No detailed exploration has been undertaken within these areas to date and simple surficial exploration programs including surface geochemical sampling and geophysics are expected to return rapid positive results for a following drilling campaign.
• A detailed ridge and spur soil sampling campaign is suggested to start as soon as possible to efficiently sample large areas on topographic highs geochemically and to prevent sampling in areas with transported cover.
• Stream sediment sampling of active drainages to discover additional anomalous areas is also suggested to rapidly and cheaply define the additional potential of the larger project area.
• LIDAR survey of topography with high resolution imagery should be undertaken along with a ground magnetic program over the main mineralized trend of Bourbon-Arabica.
• Additional detailed geological mapping of prospects and detailed underground sampling and mapping of all historical workings is essential.

Mr Brian Johnson, Chairman of Antilles Gold, said “the Company intended to undertake the low cost prospecting campaign recommended by Dr Grainger as soon as practicable provided it did not impact on resources required for the near-term development of the Nueva Sabana gold-copper mine.”
