GoldMining Hits 400m of Continuous Gold-Copper Mineralization in Colombia
Event summary
- GoldMining's Yarumalito Project in Colombia intersected 399.9m of continuous gold-copper mineralization from surface in drill hole YAR-45.
- The mineralization averaged 0.45 g/t gold equivalent (AuEq) with higher-grade intervals including 74.7m at 0.61 g/t AuEq.
- Drilling validated the P-1 porphyry intrusive suite as the primary host of mineralization, remaining open along strike and at depth.
- Four drill holes totaling 1,218m were completed on schedule and within budget, with assays pending for three additional holes.
The big picture
GoldMining's discovery at Yarumalito adds to the growing portfolio of gold-copper projects in Colombia's Mid Cauca belt, an area attracting significant investment from major miners. The continuous mineralization from surface suggests potential for a large, open-pit-friendly deposit, which could enhance the project's economic viability. The results position Yarumalito as a key asset in GoldMining's Americas-focused portfolio, competing with nearby projects from Aris Mining and Collective Mining.
What we're watching
- Resource Expansion
- Whether the remaining assay results from holes YAR-46 to YAR-48 will confirm further continuity and grade of mineralization.
- Model Refinement
- How the integration of 2026 drilling results into an updated geological model will impact resource estimates.
- Project Viability
- The pace at which GoldMining can advance Yarumalito toward pre-feasibility given its proximity to existing infrastructure and operations.
