Giant Mining Corp. (CSE: BFG; OTC:BFGFF; FWB:YW5) announced new findings from its breccia study at the Majuba Hill copper-silver-gold project in Pershing County, Nevada. The company reported that tourmaline breccia pipes have been identified in drill core, historic underground workings, and surface outcrops across the project.

According to the company, high-grade copper and silver values previously reported in its May 22, 2025, and September 24, 2024, news releases are associated with these breccia pipes. Intercepts from drill holes MHB-30 and MHB-32 included high-grade copper and silver as well as anomalous gold. The company stated that these intercepts correlate with the margins of the breccia pipes.

David Greenway, president and chief executive officer of Giant Mining, said in a company news release, “Majuba Hill is demonstrating the hallmarks of a large, copper-silver mineralized system with meaningful gold potential. Silver prices have increased by more than 150% over the past 12 months, strengthening the economics of silver-rich copper projects like Majuba. Our current geological and metallurgical programs are designed to systematically advance this system toward its full multimetal potential.”

The company also cited recent commodity market data from TradingEconomics.com. As of December 2025, copper reached a record US$6.07 per pound and was trading at approximately US$5.97/lb. Silver hit an all-time high of US$93.22 per ounce and was trading near US$90.77/oz. Gold reached a record US$4,794.85 per ounce in December 2025 and was recently trading at approximately US$4,607.70/oz. Giant Mining noted that it has not independently verified this data and that the information is provided only for general market context. The company stated that the commodity prices do not imply that Majuba Hill has demonstrated economic viability.

A summary of key intercepts shows that drill hole MHB-30 returned 243.8 meters grading 0.43% copper, 24.60 ppm silver, and 0.03 ppm gold, including 66.4 meters of 1.35% copper and 73.40 ppm silver. Drill hole MHB-32 returned 115.7 meters grading 0.33% copper, 16.97 ppm silver, and 0.04 ppm gold, including 25.9 meters of 0.64% copper and 50.89 ppm silver, and 3.0 meters grading 4.36% copper and 35.65 ppm silver. Both holes intercepted breccia margins.

The Majuba Hill project is located 113 road kilometers southwest of Winnemucca, Nevada, and 251 kilometers northeast of Reno. The property spans 9,684 acres and benefits from existing infrastructure, including county road access, proximity to Interstate 80, and regional power and water. The company reported that approximately 89,395 feet of drilling have been completed to date, with a rough replacement value of US$12.1 million. The site is a historical copper, silver, and tin producer.

According to the company, the project shows indications of a potentially large copper-silver-gold system, and drilling, including induced polarization (IP) surveys and step-out drilling, has shown expansion potential. Giant Mining has secured funding for its next phase of drilling at Majuba Hill.

Additional Breccia Zones and Assay-Backed Expansion Potential

In its investor presentation, Giant Mining reported that the Majuba Hill project includes several discrete breccia bodies, with tourmaline breccia pipes confirmed in core, surface, and historical workings. The high-grade intercepts observed in drill holes MHB-30 and MHB-32 coincide with the margins of these breccia pipes.

The company’s review of assay results highlighted that hole MHB-32 returned 115.7 meters of mineralization starting at 155.4 meters depth, with significant subintervals. A 3.0-meter section between 245.4 meters and 248.4 meters graded 4.36% copper and 35.65 ppm silver.

Infrastructure and access remain in place at Majuba Hill. The project is located near power, roads, and water, and benefits from a strong foundation for development. The company reported that the mineralization remains open in all directions, based on IP survey results, deep drilling, and step-out programs.

Giant Mining stated that it is fully financed for its next phase of exploration at Majuba Hill.
