GoldMining Commences 2026 Exploration Drilling Program at its Yarumalito Gold-Copper Project, Colombia
Rhea-AI Summary
GoldMining (NYSE American: GLDG) has started a fully funded, exploration-focused core drilling program at its 100%-owned Yarumalito gold-copper project in Colombia's Mid Cauca belt.
The diamond drill will complete about 1,200 metres, targeting the mineralized P-1 porphyry and building on historical intercepts up to 257 m at 0.50 g/t Au and 0.1% Cu from surface.

Recent positive corporate and project updates have often coincided with flat-to-negative next-day price moves, showing a tendency for the stock to underreact or sell off on good news.
Over the past six months, GoldMining has reported governance milestones, multiple economic studies and new exploration programs. Notably, an updated La Mina PEA on Apr 28, 2026 with strong $1.0B NPV and 32.2% IRR, and a fully funded 8,000-metre São Jorge drill program on Mar 30, 2026 both saw modest negative price reactions. Even the May 14, 2026 annual meeting, where all directors were elected with over 91% support, coincided with a -6.78% move. Today’s Yarumalito drilling launch fits this pattern of operational progress against a cautious tape.
Market Pulse Summary
This announcement details a fully funded 1,200-metre core drilling program at Yarumalito, targeting the mineralized P-1 porphyry and following up on long historical intercepts such as 257 m @ 0.50 g/t Au. It extends GoldMining’s 2026 exploration push alongside prior programs in Brazil and PEAs in Colombia and Alaska. Investors may track drill results, any expansion of mineralized zones, and how this complements the company’s existing economic studies and development planning across its portfolio.

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:

About Yarumalito
The
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
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.
