La Mina

Overview:

The La Mina property consists of two concession contracts and two concession contract applications covering 3,210 hectares located in the Department of Antioquia, Republic of Colombia, some 51 km SW of Medellin. The MRE for La Mina incorporates the La Cantera, La Garrucha and Middle Zone porphyry deposits located within 1,000 m of each other.

From late March to mid-August 2022, GoldMining completed a diamond core drilling program comprising five drill holes for 3,485 m at the La Garrucha deposit, a porphyry mineral system which measures over 400 m in strike length by 300 m in width and to at least 775 m below surface where it remains open. Gold and copper mineralization in the La Garrucha porphyry intrusive complex is accompanied by strong potassic alteration, characterized by secondary potassium feldspar and biotite, disseminated and vein magnetite, quartz stockwork veining and both vein-hosted and disseminated sulphides that include pyrite, chalcopyrite and lesser bornite.

This maiden drill program for GoldMining Inc discovering the La Garrucha deposit adds approx. 1.0 million oz AuEq in the Inferred category and 0.2 million oz AuEq in the Indicated category at a cost of only $1.2 million.
