GoldMining Commences 2026 Exploration Drilling Program at its Yarumalito Gold-Copper Project, Colombia

 GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) (the "Company" or "GoldMining") is pleased to announce that it has commenced an exploration-focused core drilling program on its 100%-owned Yarumalito Gold-Copper Project ("Yarumalito" or the "Project") in the Mid Cauca gold-copper belt of Antioquia, Colombia.

Highlights:

• Fully Funded Drill Program Underway: The diamond core drill is actively turning on site for an approximate 1,200-metre systematic program.
  
  
• Testing a New and Enhanced Geological Model: Drilling will follow-up on high priority targets previously identified through comprehensive relogging of historical core.
  
  
• Expanding the Mineralized P-1 Porphyry: Testing new zones of potential bedrock mineralization in under-drilled portions of the host 'P-1' porphyry unit, the principal host of gold-copper ("Au-Cu") mineralization at the Project.
  
  
• Building on Historical Drill Intercepts:
  
  
  • 257 metres ("m") at 0.50 grams per tonne ("g/t") gold ("Au") and 0.1% copper ("Cu") from surface (YAR-06)
    
    
  • 250 m at 0.51 g/t Au and 0.13% Cu from surface (YAR-08)
    
    
  • 141.4 m at 0.77 g/t Au and 0.09% Cu from surface (YAR-11)

Alastair Still, President and Chief Executive Officer of GoldMining, commented: "Yarumalito sits in the heart of Colombia's prolific Mid Cauca belt, in close proximity to major discoveries like Collective Mining's Guayabales project and Aris Mining's Marmato mine. With diamond core drilling now underway on our second active exploration drilling program in the Americas for 2026, we are testing a newly refined geological model at Yarumalito. This large, highly accessible gold-copper porphyry system remains open in all directions and the targeted drill program is our first step in seeking to unlock the substantial step-out growth potential of the mineralized P-1 host unit."

About Yarumalito

The 100% owned Yarumalito project is located in the Mid Cauca Au-Cu Belt of central Colombia, approximately 105 kilometers south-southwest of Medellín, Colombia's second most important economic center, and 40 kilometers south of the Company's La Mina project. Neighbouring projects include Aris Mining Corporation's Marmato Gold Mine and Collective Mining Ltd.'s Guayabales 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 ("MRE") was previously completed by the Company on the Project based on 50 historical drill holes (drilled between 2005 and 2013) containing approximately 18,000 m of core. The MRE comprises 66.3 million tonnes at 0.58 g/t Au and 0.09% Cu for 1.23 million ounces Au and 129 million pounds Cu of estimated inferred mineral resources. For further information regarding the Project, including the MRE, please see the 'Technical Report Yarumalito Gold-Copper Property, Departments of Antioquia and Caldas, Republic of Colombia', with an effective date of April 1, 2020, a copy of which is available under the Company's profile on SEDAR+ at www.sedarplus.ca.

The approximate 1,200 m 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.
