Giant Mining Soil Sampling Expands Mineralized Breccia Footprint with Anomalous Copper and Silver at Majuba Hill Copper-Silver-Gold Project

Executive Summary

• 96 new soil samples at Majuba Hill extend the known copper‑silver breccia footprint, with 21 samples >100 ppm Cu (max 397 ppm) and 24 samples >2 ppm Ag (max 9.5 ppm).
• Anomalous copper zones now outline a potential eastward extension of mineralization up to ~1,000 ft, aligned with northwest‑fault corridors that control breccia bodies.
• Company confirms it is fully financed for the next drilling phase and will use these results to refine drill targets and geological models.

Key Details

• Soil Sample Results: 21/96 samples >100 ppm Cu (max 397 ppm); 24/96 samples >2 ppm Ag (max 9.5 ppm).
• Survey Purpose: Fill gap in existing 3,412‑sample grid; identify extensions of copper mineralization eastward (~1,000 ft).
• Geological Interpretation: High‑Cu zones oriented northwest align with Northwest Fault Corridors, a primary structural control on breccia bodies in both Southern and Northern Breccia Zones.
• Silver Correlation: Silver anomalies (>1.1 ppm) co‑locate with copper zones, reinforcing the fault‑controlled mineralization model.
• Historical Drill Highlight (MHB‑30): 66.4 m of 1.35 % Cu and 73.4 g/t Ag; includes 22.6 m of 2.6 % Cu and 30.1 g/t Ag (Sept 24, 2024 release).
• Project Overview: Majuba Hill, Nevada – 9,684 acres; ~89,395 ft drilled to date (≈US$12.1 M replacement value); fully financed for next drilling phase.
• Infrastructure: Accessible via county roads from I‑80; proximity to Winnemucca and Reno provides road, power, water advantages.
• QA/QC Protocols: Chain‑of‑custody handled by ALS Labs; duplicate sampling ~5 %; analysis methods include fire assay for Au and ICP‑AES for Cu/Ag/31 other elements.
• Qualified Person: E.L. “Buster” Hunsaker III, CPG 8137 (non‑independent consulting geologist).

“These new soils demonstrate the potential for expanding the Majuba Hill mineralization. Our Technical Program continues to expand the geologic framework that supports our drill planning and improvements in the Geological Model by RESPEC. I am excited to proceed to the next phase of drilling.” – David Greenway, President & CEO, Giant Mining Corp.
