GoldMining Inc. (NYSE American: GLDG) has started a 1,200-meter core drilling program at its Yarumalito Gold-Copper Project in Colombia's Mid Cauca gold-copper belt.

The exploration program will test four drill holes targeting the P-1 porphyry unit, which hosts the primary gold-copper mineralization at the site. Three holes will examine the geometry and extent of porphyry-style mineralization, while a fourth will target epithermal veins from historical mine workings.

The project is located approximately 105 kilometers south-southwest of Medellín and sits near Aris Mining Corporation's Marmato Gold Mine and Collective Mining Ltd.'s Guayabales Project. GoldMining owns 100% of the property.

Historical drilling between 2005 and 2013 produced notable intercepts, including 257 meters at 0.50 grams per tonne gold and 0.1% copper from surface, and 250 meters at 0.51 grams per tonne gold and 0.13% copper from surface.

An existing mineral resource estimate based on 50 historical drill holes contains 66.3 million tonnes at 0.58 grams per tonne gold and 0.09% copper, representing 1.23 million ounces of gold and 129 million pounds of copper in estimated inferred mineral resources.

"This large, highly accessible gold-copper porphyry system remains open in all directions," said Alastair Still, president and chief executive officer of GoldMining.

The current drilling program represents the company's second active exploration program in the Americas for 2026, according to the company's statement.
