Giant Mining plans further met testing for Majuba Hill
Executive Summary
- Giant Mining Corp. announced a new, comprehensive metallurgical testing program at its Majuba Hill copper‑silver‑gold project in Nevada to refine recovery estimates for oxide, transition and sulphide zones.
- The release highlights historic high‑grade drill intercepts (e.g., Hole MHB‑30: 74 ft @ 2.6% Cu & 30.1 g/t Ag) and previous metallurgical results indicating up to ~80% copper and ~75% silver recoveries.
- Objectives include evaluating heap‑leach, flotation and vat‑leaching options, assessing downstream silver/gold circuits, and generating data for future economic studies.
Key Details
- Planned Metallurgical Program
- Assess oxide, mixed and sulphide mineralization domains.
- Improve understanding of Cu, Ag, Au recovery processes.
- Test multistage processing options: heap leach, flotation, vat leaching.
- Evaluate downstream circuits for silver and gold.
-
Produce technical data to support resource delineation and future economic modeling.
-
Historical Drill Highlight
-
Hole MHB‑30: 74 ft averaging 2.6% Cu & 30.1 g/t Ag; within 218 ft averaging 1.35% Cu & 73.4 g/t Ag.
-
Historic Metallurgical Findings (for context)
- Acid vs. cyanide leach (2012): ~60% Cu recovery low‑grade, ~70% mid‑grade after ferric iron adjustment.
- Laurion Consulting composite test (2013): 81.1% Cu extraction at 6 mesh & 84.6% at 200 mesh over 14‑day leach on 0.62% Cu / 34.6 g/t Ag sample.
-
Flotation study (2017): Silver recovery ranged from 44.5% to 74.9% depending on collector concentration and pH.
-
Project Overview
- Location: Pershing County, Nevada – 9,684 acres.
- Infrastructure: Near major roads, power and water; ~113 km SW of Winnemucca, 251 km NE of Reno.
- Drilling to date: ~89,395 ft (≈$12.1 M replacement cost at current rates).
-
Status: Fully financed for next drilling phase; historic producer with significant expansion potential indicated by IP surveys and step‑out drilling.
-
Qualified Person
- Review and approval by E.L. “Buster” Hunsaker, CPG No. 8137 (non‑independent consulting geologist).
