Excelsior Mining
Excelsior Mining Corp. operates the Gunnison Copper Project in Arizona, known for its eco-friendly In-Situ Recovery mining, and owns the Johnson Camp Mine and other exploration projects.
Gunnison Copper Project
Excelsior Mining Corp. operates the Gunnison Copper Project in Cochise County, Arizona. The project is notable for its low-cost, environmentally-friendly approach to copper production, utilizing In-Situ Recovery (ISR) mining which involves minimal surface disturbance. The Gunnison Copper Project is permitted to produce 125 million pounds of copper cathode annually and is expected to generate 2.15 billion pounds of pure copper cathode over its 24-year mine life. Initially, production starts at 25 million pounds per year and ramps up to 125 million pounds annually. The pre-production capital cost for the project is $47.6 million.
Johnson Camp Mine
The Johnson Camp Mine, owned by Excelsior Mining Corp., is a past-producing mine that the company plans to restart. The mine is situated just over a mile from the Gunnison Copper Project’s wellfield and processes copper-bearing solutions through its Solvent Extraction-Electrowinning (SX-EW) facility. The SX-EW process produces 99.999% pure copper cathode. The proximity to the Gunnison project allows for efficient resource utilization and operational synergies.
Exploration Projects
Excelsior Mining Corp. is involved in several exploration projects including the Strong and Harris and Peabody Sill Deposits. The Strong and Harris deposit, located 1.3 miles north of the Johnson Camp SX-EW facility, involves traditional open-pit mining as well as high-grade underground mining of remaining sulfides. Combined, the Peabody Sill and Strong and Harris projects have a mine life of approximately 7 years and are expected to produce a total of 437 million pounds of copper and 575 million pounds of zinc.
Environmental Responsibility and ESG Initiatives
Excelsior Mining Corp. is committed to environmental stewardship and sustainability, implementing various ESG (Environmental, Social, and Governance) principles. The company uses eco-friendly mining techniques such as ISR (In-Situ Recovery) mining, which minimizes surface disturbance. Additionally, Excelsior Mining collaborates with the EPA to amend its Underground Injection Control (UIC) permit to include well stimulation. The company actively supports local communities through initiatives like STEM programs in schools, cultural museum sponsorships, and contributions to local fire departments, hospitals, and recreational events.
