GoldMining Inc. has commenced an exploration-focused core drilling program on its 100%-owned Yarumalito Gold-Copper Project in the Mid Cauca gold-copper belt of Antioquia, Colombia. The diamond core drill is actively turning on site for an approximate 1,200-metre systematic program. Drilling will follow-up on high priority targets previously identified through comprehensive relogging of historical core.
Testing new zones of potential bedrock mineralization in under-drilled portions of the host 'P-1' porphyry unit, the principal host of gold-copper mineralization at the Project. Building on historical drill intercepts: 257 metres at 0.50 grams per tonne gold and 0.1% copper from surface (YAR-06), 250 metres at 0.51 grams per tonne gold and 0.13% copper from surface (YAR-08), 141.4 metres at 0.77 grams per tonne gold and 0.09% copper from surface (YAR-11). The 100% owned Yarumalito project is located in the Mid Cauca Au-Cu Belt of central Colombia, approximately 105 kilometers south-southwest of Medellín, and 40 kilometers south of the Company's La Mina project.
Gold-copper mineralization is related to porphyry intrusive bodies of potassic altered diorite with disseminated and fracture-controlled pyrite, chalcopyrite and magnetic, which is cross-cut by structurally controlled intermediate sulphidation epithermal veins containing pyrite, galena, sphalerite and chalcopyrite. An existing mineral resource estimate was previously completed by the Company on the Project based on 50 historical drill holes containing approximately 18,000 metres of core. The mineral resource estimate comprises 66.3 million tonnes at 0.58 grams per tonne gold and 0.09% copper for 1.23 million ounces gold and 129 million pounds copper of estimated inferred mineral resources.
The approximate 1,200 metres planned core drilling program is expected to comprise three drill holes to test the geometry and extents of the porphyry-style of mineralization in the 'P-1' intrusive phase, which is demonstrated from systematic relogging of historical drill core to represent the principal host lithology of the gold and copper mineralization. A fourth drill hole is planned to target epithermal veins mapped from abandoned underground historical mine workings, with the objective to test the geometry, width and grade characteristics of the over-printing epithermal mineralization. The minor underground historic workings are not active and there is no known artisanal mining occurring on the Property.
