Thick Intervals Of Oxide Copper At Majuba Hill

VANCOUVER – Giant Mining Corp. reported on Phase 1 of the Spring 2025 diamond drilling program including core holes MHB-33, MHB-34, and MHB-35, completed at the Majuba Hill Porphyry Copper-Silver-Gold Project in Pershing County, Nevada. These results from the Core Program confirm strong breccia controls and significant high-grade copper mineralization and correlate with high-grade intercepts previously identified in core holes MHB-30 and MHB-32. The primary objective of the Core Program was to delineate and better understand the geometry and extent of the copper-bearing breccia zones. Assay results and geological interpretation outline a large, distinct copper-mineralized breccia body at Majuba Hill.

Copper within the Mineralized Breccia Body in MHB-34 included enriched and primary (hypogene) copper mineralization: 1) 500 ft (152.4 m) @ 0.21% Cu from 1210-1710 ft (368.8-521.2 m) including165 ft (50.3 m)@ 0.24% from 1280-1445 ft (390.1-440.4 m). 2) 205 ft (62.5 m) @ 0.27% Cu from 1605-1710 ft (458.7-521.2 m). 3) 55 ft (16.8 m) @ 0.41% Cu from1505-1560 ft (458.7-475.5 m).

Core hole MHB-34 intersected long intervals of copper mineralization within both the main Mineralized Breccia Body and the Marginal Breccia Zone. Meanwhile, holes MHB-33 and MHB-35 focused on shallower portions of these zones. The new results confirm, extend, and further define the continuity and significance of breccia-controlled copper mineralization across the project.

Core hole MHB-32 intersected two significant copper-mineralized zones within a broader interval of 379.5 feet (115.7 m) grading 0.33% Cu and 16.97 ppm Ag, from 510 to 889.5 feet (155.5 to 271.1 m). These results extended known mineralization deeper and further north than previous drilling.

David Greenway, CEO, said, “The assay results from MHB-33, MHB-34, and MHB-35 are very positive and continue to validate the scale and continuity of breccia-hosted copper mineralization at Majuba Hill. With copper emerging as a national security priority under the current U.S. administration, and Nevada ranked as the number one mining jurisdiction in the United States, the stars are aligning for Giant Mining. We’re fully funded for the next phase of drilling, and our team — led by Buster Hunsaker — is eager to launch Phase 2. We’re incredibly proud of the work accomplished so far and excited about what lies ahead as we advance our mission to help reshore America’s copper supply.”
