Giant Mining Corp. Advances Metallurgical Test Work at Majuba Hill Nevada Copper-Silver-Gold Project as Metal Prices Hit Records

Executive Summary

• Giant Mining Corp. announced plans to conduct additional metallurgical test work at its Majuba Hill Copper‑Silver‑Gold Project in Nevada to refine recovery estimates for copper, silver and gold across oxide, transition and sulphide zones.
• The program builds on historic drill results (e.g., Hole MHB‑30: 74 ft @ 2.6% Cu & 30.1 g/t Ag) and earlier metallurgical studies that suggested up to ~80% Cu and ~75% Ag recoveries.
• Objectives include evaluating oxide, mixed and sulphide domains, testing heap‑leach, flotation and vat‑leaching options, and generating data for future economic studies.

Key Details

• Project Focus: Majuba Hill (9,684 acres) in Pershing County, Nevada – a historic copper‑silver‑gold porphyry system with existing infrastructure and road access.
• Historical Drill Highlight: Hole MHB‑30 returned 74 ft averaging 2.6% Cu and 30.1 g/t Ag; within 218 ft averaging 1.35% Cu and 73.4 g/t Ag.
• Historic Metallurgical Findings (for context):
• Acid vs cyanide leach testing (2012) – estimated Cu recoveries of ~60% (low‑grade), ~70% (mid‑grade).
• Laurion Consulting composite leach (2013) – ~81.1% Cu extraction at 6‑mesh and ~84.6% at 200‑mesh over a 14‑day cycle on a 0.62% Cu / 34.6 g/t Ag sample.
• Flotation study (2017) – silver recoveries ranging from 44.5% to 74.9%.
• Planned Metallurgical Program Objectives:
  1. Assess oxide, mixed and sulphide mineralization domains.
  2. Improve understanding of Cu, Ag, and Au recovery processes.
  3. Evaluate multi‑stage processing options (heap leach, flotation, vat leaching).
  4. Evaluate downstream silver and gold circuits.
  5. Generate new technical data for mineralization delineation and future economic studies.
• Funding Status: Company states it is “Fully Financed” for the next phase of drilling at Majuba Hill (no specific dollar amount disclosed).
• Qualified Person: E.L. “Buster” Hunsaker III, CPG 8137, a non‑independent consulting geologist, reviewed and approved the technical information under NI 43‑101 standards.
• Market Context (non‑material): Recent all‑time highs for copper ($5.94/lb), silver ($58.85/oz) and gold ($4,381.58/oz) are cited to illustrate a favorable price environment; no economic viability claim is made.

Notable Quotes

• David Greenway, President & CEO: “Majuba Hill is showing excellent potential as a district‑scale copper‑silver project with meaningful gold credits… Updating this work is the natural next step as we advance Majuba Hill.”
