07:51 AM EDT, 10/20/2025 (MT Newswires) -- GoldMining ( GLDG ) was at last look up 4.5% in US premarket trade Monday as it reported initial assay results from its previously announced 2025 RC drilling program at its 100% owned Sao Jorge Project in the Tapajos gold district, Brazil.

Among highlights, GoldMining ( GLDG ) cited new exploration discoveries at four new gold prospects within 3.5 kilometre radius of the existing Sao Jorge deposit; and noted a total of 8,514 meters of drilling were completed to date, comprising 3,862 meters diamond core, 2,553 meters RC and 2,100 meters auger drilling, of a total planned drilling program of up to 5,000 meters diamond core and 3,000 meters auger drilling.

A statement noted the ongoing program, including reverse circulation drilling results, is designed to test new targets outside of known areas of mineralization and is the most extensive exploration program undertaken by the company to date. It said results from other components of the program, including drilling designed to target expansion of the Sao Jorge deposit, will be reported as results are available.

CEO Alastair Still said: "GoldMining ( GLDG ) is excited to report initial exploration results from our 2025 exploration program designed to test for new targets, outside of known areas of mineralization, at our Sao Jorge Project. These initial assay results demonstrate at least 4 new zones of mineralization that have never previously been drilled, each of which occurs more than 1 km away from previously known mineralization. The nature and style of mineralization, similar to that of the existing mineral resources at the Sao Jorge deposit, has ideally positioned us for follow-up drilling that will be designed to better define and quantify additional near-surface mineralization occurring over a 12 km x 7 km geochemical footprint identified over the Sao Jorge property-scale mineral system.

"In addition to furthering our exploration of these newly identified targets, we have further exploration results pending that tested for additional zones of mineralization, including drilling that targeted extension of the known mineral resource area. The excellent infrastructure at the 46,000 hectare project includes an existing 50-person camp and easy access to paved highway and grid power that has facilitated our exploration activities as we advance our programs to better quantify the gold endowment of this highly prospective regional-scale property in the rapidly emerging Tapajos gold district."
