PHOENIX, Arizona–(Newsfile Corp. – July 31, 2023)– Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQB: EXMGF) (“Excelsior” or “Company”) is an option contract (“agreement“) Partnered with Newton LLC, a Rio Tinto venture, to further evaluate the use of Newton™ copper heap leaching technology at Excelsior’s Johnson Camp Mine in Cochise County, Arizona. Under this agreement, Excelsior will continue to be the operator, and Newton will fund Excelsior’s related costs.Newton will advance Excelsior’s US$3 million for the cost of the first phase of its two-phase work program at Johnson Camp, It will then pay US$2 million as an exclusive option to establish a joint venture with Excelsior over the Johnson Camp mine, Stage 2 completed.
“We are delighted to be working with Nuton to move Camp Johnson forward. Their support and technology has the potential to realize the value of Camp Johnson’s sulfide resource in an economically and environmentally beneficial manner. Johnson “We may make progress toward improving cash flow while continuing to develop other assets, such as advancing Gunnison for a full stimulus trial later this year,” said Camp. CEO Steven Twiard commented: “The strength of this deal is that both the Gunnison and Johnson campaigns can move forward in parallel.”
Rio Tinto develops NewtonTMs The technology is a broad portfolio of advanced copper heap leaching techniques targeting primary sulfide minerals (including low-grade deposits) that could not be processed using conventional leaching and sulfide treatment techniques. . These technologies offer the potential to produce additional copper in a cost-effective manner, with significant environmental benefits and reduced waste from new and ongoing operations.
Under the terms of the contract, the Stage 1 work program will include Excelsior’s completion of diamond drilling, permitting of activities, detailed engineering and project execution planning. Nuton completes mineralogy, predictive modeling, engineering and other testing work. Based on the results of the Stage 1 work program, Nuton has the option to proceed to Stage 2. The Stage 1 work program will begin in August and is expected to take six to nine months to complete.
If Newton proceeds to Stage 2, it will pay Excelsior US$5 million to use existing infrastructure at the Johnson Camp mine for the Stage 2 work program. Nuton will also be responsible for funding all Excelsior costs related to Stage 2. The full program of work for Stage 2 is expected to take up to five years, including engineering and mobilization, infrastructure and construction, mining, leaching, copper production and post-leaching cleaning. Mining is expected to start in Year 1. Once all milestones are complete, multi-year full-scale commercial production at Johnson Camp with Nuton will begin.TMs technology. The operating income will first be used to reimburse his Nuton for Stage 2 expenses and then credited to his Excelsior account.
Upon completion of Stage 2, Newton will have the right to establish a joint venture at Johnson Camp on mutually agreed terms, resulting in Newton’s initial 49% ownership and Excelsior’s initial 51% ownership. The purpose of the joint venture is to continue the development of the Johnson Camp Mine using Nuton.TMs technology. If Nuton does not exercise its joint venture rights, Nuton and Excelsior will negotiate in good faith regarding Excelsior’s continued use of his Nuton™ technology at Johnson Camp Mine, subject to certain licensing terms. Infrastructure development at Johnson Camp under this agreement is non-exclusive. During Stages 1 and 2, Excelsior may continue to use its Camp Johnson infrastructure to process Gunnison solutions and other copper sources unrelated to the Stage 2 work program as long as the capacity requirements of the Stage 2 work program are met. there is.
About Newton
Nuton is an innovative new venture aimed at helping Rio Tinto grow its copper business. At Nuton’s core is a portfolio of proprietary copper leaching-related technologies and capabilities that are the result of nearly 30 years of research and development. Nuton technology economically liberates known low-grade copper sulfide resources, copper-bearing waste and tailings, offers the potential to achieve higher copper recovery from oxides and transitional materials, and improves copper production outcomes. can be greatly improved. One of Nuton’s key differentiators is its potential to deliver superior environmental performance, including improved water efficiency, reduced carbon footprint, and the ability to regenerate post-mine sites by reprocessing mine waste. There is something.
