Barton Gold (BGDFF) is drilling at its Tarcoola Gold Project’s Tolmer prospect in South Australia, targeting structural controls within the ‘eastern gold zone’. The Tolmer discovery shows promise with grades up to 83.6g/t Au and 17,600g/t Ag. A March 2025 discovery hole had the 5th highest-grade silver intersection globally in H1 2025 (6m @ 4,747 g/t Ag). Recent assays extended high-grade silver horizons and revealed high-grade gold up to ~13g/t Au, in a 1.5km wide mineralized zone.

Questcorp Mining has commenced its maiden 1,500m drilling program at the La Union Gold & Silver Project in Sonora, Mexico, targeting CRD mineralization. Operated by Riverside Resources, the program focuses on four key areas with historical gold production. Questcorp’s initial C$1,000,000 exploration is part of a C$5,500,000 commitment. Historical sampling revealed high grades (e.g., 59.4 g/t gold, 833 g/t silver), suggesting potential for large-scale gold discoveries. The drilling aims to assess alteration and identify robust mineralized systems in previously mined areas.

Mines d’Or Orbec (BLUE) completed a 2,000+ meter drilling campaign at its Muus property in Quebec’s Abitibi Greenstone Belt, focusing on the Lac Bernard area. Drill holes intersected silicified and pyrite-bearing zones, geological indicators of gold mineralization. The property is near IAMGOLD’s Nelligan Deposit. The company awaits assay results in approximately 6 weeks. Additionally, Orbec granted stock options for 4,150,000 common shares at $0.06 per share, expiring July 11, 2030.

Solis Minerals (ASX: SLM) is advancing a major copper-gold exploration campaign in Peru’s coastal copper belt, launching three key projects: a 2,500m drilling program at Chancho al Palo (targeting porphyry/IOCG systems), permitted 5,000m drilling at Ilo Este by 2025, and an IP survey near Southern Copper’s Toquepala mine. Positioned in a region producing 19% of global copper, Solis benefits from full asset ownership and proximity to infrastructure. Risks include regulatory delays and copper price volatility ($4.50/lb). Peru aims to double copper output by 2030, driven by green tech demand. SLM shares rose 4.3% post-announcement, with A$12.6M working capital supporting operations.
