Intrepid Metals Secures Additional Mineral Rights Adjacent to Rio Tinto at Corral Copper
[email protected] Vancouver, British Columbia - Newsfile Corp. - July 2, 2025 -or the) is pleased to announce the strategic expansion of its Corral Copper Property ("Corral" or the "Property") in Cochise County, Arizona through the acquisition of an additional four state leases from the Arizona State Land Department ("ASLD") and another patented mining claim (the Emmet Claim) from Silver Nickle Mining Company. These new claims, located on the eastern border of Intrepid's existing land package (see Figure 1 below), significantly enhance the Company's regional footprint. Notably, several of the newly acquired state leases bridge the southern gap between Intrepid's holdings and recently acquired claims by Rio Tinto. The property acquisition by Rio Tinto followed Intrepid's successful 2024 drill program, which highlighted the Property's potential and drew significant regional interest. Please refer to Intrepid News Release dated January 15, 2025 for further new claims increase Corral's total land package by approximately 2,195 acres (888 hectares), bringing the Company's consolidated holdings to 11,715 acres (4,741 hectares). This positions Intrepid to further capitalize on the district's exploration upside and reinforces its presence in one of Arizona's most prospective copper belts."The expansion of our land position at Corral reflects our continued confidence in the district's potential and our commitment to building a meaningful copper asset in a tier-one jurisdiction," stated Ken Engquist, Chief Executive Officer of Intrepid. "By securing these strategically located state leases, we've strengthened our competitive position alongside a major industry player and set the stage for further value creation through exploration."The Corral Copper Property, located near historical mining areas, is an advanced exploration and development opportunity in Cochise County, Arizona. Corral is located 15 miles east of the famous mining town of Tombstone and 22 miles north of the historic Bisbee mining camp which has produced more than 8 billion pounds of copper. Production from the Bisbee mining camp, or within the district as disclosed in the next paragraph, is not necessarily indicative of the mineral potential at district has a mining history dating back to the late 1800s, with several small mines extracting copper from the area in the early 1900s, producing several thousand tons. Between 1950 and 2008, various companies explored parts of the district, but the effort was uncoordinated, non-synergistic and focused on discrete land positions and commodities due to the fragmented ownership. There is over 50,000m of historical drilling at Corral mainly centered on the Ringo, Earp and Holliday Zones and although this core has been destroyed, Intrepid has a historical digital drill hole archive database which the Company uses for the purposes of exploration targeting and drill hole planning.

Cutting edge copper: can innovation help meet rising demand?
Sixty-five miles east of the sun-drenched city of Tucson, Arizona, lies the historic copper mine, Johnson Camp. Active on and off since the 1970s, the mine is being resurrected in response to a booming copper market. As material is extracted at the mine, it will be separated into different piles; oxide copper in one pile and primary sulphide copper in another. The former will be sent to one portion of the heap leach pad for conventional oxide leaching using hydrometallurgy. The sulphides will leach using novel technology developed over three decades by Rio Tinto. Johnson Camp, now operated by Gunnison, will be the scene of the first industrial-scale trial to prove the technology's efficacy – a major milestone since Rio Tinto launched a new venture called Nuton to develop it in 2021. After the technology is installed in August, first copper is expected by the end of 2025. Primary sulphide ore, typically dominated by copper deporting to the mineral chalcopyrite, is the most abundant type of copper ore in the world. It is typically crushed and milled producing a flotation concentrate. This flotation concentrate is then typically smelted using a heat intensive pyrometallurgical process, casting the copper into raw copper anodes, which are then electro-refined to produce a pure copper product. Nuton's process, however, uses a unique culture of microorganisms added to the ore. These bacteria multiply, harnessing energy from the oxidation of minerals in the rock to grow and simultaneously assist with leaching of the copper, achieving a recovery rate of up to 85%. Aeration and acidified water support the process with subsequent processing of the leach solutions producing 99% pure copper cathode. Bioleaching is just one of several novel methods conceived to extract more copper from new and existing mines – including copper previously considered uneconomical because of low grades or small deposits – more sustainably and more quickly to meet the growing demand. The International Energy Agency predicts a 30% shortfall in supplies of copper, a key component in electricity networks, by 2035 if nothing is done. This is against a wider expectation that to achieve net zero, copper demand will grow from 25 million tonnes (mt) in 2021 to 31.3mt by 2030. At Johnson Camp, the plan is to optimise Nuton's technology so it can be adopted at a commercial scale across a portfolio of around ten partnerships Nuton has been brokering. 'It feels like a special moment,' says CEO Adam Burley, who has worked at Rio Tinto for more than 20 years. 'With data, analytics and AI there is an enormous ability to rapidly evaluate the performance of the technology and run different scenarios around the operating conditions and how we apply and adjust it – we couldn't have done that 30 years ago.' Perhaps most notably, the technology does not require a concentrator in the processing of primary sulphides, potentially making it much cheaper and requiring a much smaller footprint. 'Concentrators can be difficult to permit, they are more water intensive and produce a concentrate that needs to be exported for smelting and refining into a finished product,' explains Burley. 'Nuton offers an economic, high-recovery solution, potentially comparable to a concentrator, but with less land use and water consumption to produce a finished copper cathode which can be, in part, consumed domestically.' This is a prospect that can reduce an over-reliance on China, which produces 40% of copper. The current expectation is that the overall capital expenditure and operating expenses of bioleaching will also be less, with the copper recovery from primary sulphides expected to be higher (although this may vary). One drawback of this kind of technology, however, is that if the base carries commercial levels of by-product, such as gold, the process cannot currently recover both. Meanwhile, BHP Billiton has invested in Chilean start-up Ceibo, a company that started as a dust mitigator business but moved into copper extraction after spotting an opportunity. Rather than using bio-leaching processes – which it considers not as "controllable" – Ceibo has developed electrochemical reactions that catalyse the oxidation in primary sulphide ores. This is a faster and cleaner process for extracting copper sulphides, according to the company. In early June, Ceibo announced delivery of its first copper cathodes from a demonstration plant at a mine site in northern Chile owned by Cia. Minera San Geronimo. Marketing consultant Radhika Iyer says the technology can be used with low ore grades and chalcopyrite. 'Ceibo's process can extend the life of a mine, is less capital intensive, has a smaller footprint and reduced cost compared to building a concentrator and refining,' Iyer explains. The technology is currently being scaled, including in collaboration with Glencore, and has been tested on 50 different ores. In the US, Endolith, headed by professor Liz Dennett, is, like Nuton, developing technology that uses microbes – the "Earth's oldest miners", as she puts it – to produce copper. Dennett has a PhD in astrobiology and worked for NASA looking at how microbial life can oxidise and reduce iron and sulphur – the core of what happens in heat leaches, she says. In May, Endolith reached a milestone when it demonstrated a significant uplift in copper recovery from low-grade sulphide ores during testing in simulated field conditions. The tests used samples provided by BHP. Dennett, who previously worked as a lead architect at AWS building cloud native platforms, as well as a vice-president at Wood McKenzie, says the technology uses "logical intelligence". 'We are evaluating microbial communities with real-time diagnostics to get the most from low-grade ores such as chalcopyrite and mixed sulphides that are increasingly challenging to extract,' explains Dennett. The microbes are housed in a shipping container and can be plugged into existing systems. Endolith, which is working with six copper producers, is preparing to launch its first field deployments. There are several other companies working on scaling similar nascent technologies, including Destiny Copper, Still Bright, Jetti Resources and Kofiln, which speaks to the big opportunity the market has identified. Jack Kennedy, a climate and mining investor at Founders Factory – a partner in Rio Tinto's Accelerator Programme, as well as an investor in Endolith – says mining is a $2trn industry with so little investment to date that the potential of these technologies is significant. 'Each one can potentially crossover in the future and work together, which would be very interesting for us to see. It is a big, big market,' he says. If successfully proven at scale, these technologies could be in widespread use by the end of the decade. There have been setbacks, however: Freeport-McMoRan, an early investor in Jetti, partnered with the start-up at its El Abra mine in Chile, but is no longer using the company's technology, instead pursuing its own. One of the biggest challenges start-ups face is winning mining companies' trust, says Dennett. 'Another is these heaps are very dynamic, ore grades have fallen from around 3% a century ago to 0.7% now; we need to ensure our technology can address high impurity ores using higher concentrations of salt water or brackish water, that these microbes can thrive in any conditions,' she says. Nevertheless, Dennett is bullish, not just Endolith's potential but also her competitors'. 'This truly is 'a rising tide lifts all ships', because if you consider the amount of copper we need by 2050 all of these technologies will be needed; if we can go to mines already in production and extract 90% or more copper it will minimise mining's footprint,' Dennett adds. Wheaton Precious Metals president and CEO Randy Smallwood says trying to increase what can be extracted from an existing mine 'makes all the sense in the world'. 'The industry should focus on measures including technology and efficiency that can maximise what is extracted from existing mines as well as lowering [environmental] impact where possible,' he says. 'Some of that comes from technology and some from regulatory frameworks [allowing mine expansion].' This is part of the ethos behind Wheaton's $1m Future of Mining Challenge award for innovation, he says. 'What it all comes down to is more product with less impact, trying to minimise either the carbon loading or improving or increasing the amount of copper recovered,' he says. Eric Saderholm, managing director of exploration, American Pacific Mining, who has worked in the copper industry for four decades, agrees these technologies 'check most of the boxes'. 'The world [currently] produces approximately 25mt of copper per year and that's not sustainable [to meet demand if you are] only using traditional smelting and higher-grade ores going through smelters,' he says. 'Bioleaching will fill a necessary gap in global demand. In particular, it is going to open up doors for smaller deposits worldwide that can be exploited relatively quickly.'

Critica taps rare earths expert Jacob Deysel as new CEO
Critica Limited has landed a major coup in the hunt for leadership firepower by appointing seasoned mining executive Jacob Deysel as its new chief executive officer to spearhead the transition of its Western Australian Jupiter project from explorer to developer. Deysel will take up the reins in two weeks. Over a 25-year career in global mining, he has held top positions with industry titans, including Rio Tinto, Newmont, Uranium Energy Corp and Kenmare Resources. Most recently, Deysel was chief executive officer and managing director of ASX-listed Mineral Commodities Limited. The Jupiter project, part of Critica's broader Brothers project, has Australia's largest and highest-grade clay-hosted rare earths resource, which clocks in at a massive 1.8 billion tonnes. The project is ideally located between the mining hub of Mt Magnet and the export-ready Port of Geraldton, combining a world-class jurisdiction with world-class infrastructure. With Deysel now at the helm, the company says it's poised to fast-track scoping and feasibility studies as it aims to develop the project and become a globally significant Western-aligned rare earths supplier. Deysel is a qualified mining engineer with an MBA and executive training from London Business School. Critica says the company was specifically looking for someone with his particular skill set for boosting value in rare earths, graphite and mineral sands projects worldwide. Coupled with his strong buyer network, a good knowledge of investors' needs and access to governments across the world, Deysel's expertise is likely to be invaluable for Critica. His appointment couldn't be better timed. Critica's first-pass beneficiation test work on Jupiter has already returned an eye-popping 830 per cent uplift in grade with more than 50 per cent rare earth recovery. The mining veteran's hands-on knowledge of rare earth element feedstocks and beneficiation processes should position him well to turn those results into real value. Deysel also brings considerable commercial nous, having previously secured offtake deals, memoranda of understanding partnerships and government funding for rare earths ventures, along with founding his own rare earth element-focused company, Sheerartar Minerals. Critica Limited incoming chief executive officer Jacob Deysel said: 'I have undertaken extensive due diligence on Critica's assets and believe Jupiter has the potential to become a globally significant rare earth project. With its scale, grade and location in Western Australia, we have a clear pathway for expeditious development through scoping and feasibility.' As part of his remit, Deysel will also lead a strategic review of Critica's Mt Lindsay tin-tungsten asset in Tasmania, which is one of the largest undeveloped projects of its kind globally. The minerals are increasingly vital to global supply chains, adding to the company's critical minerals credentials. To back the new boss and his ambitious plans, non-executive directors Tim Lindley and Nick Cernotta have agreed to receive equity in lieu of fees from today, in a sign they are big believers in the company's long-term prospects. The company has signed off on a $360,000 annual salary package for the new executive. He has also been granted 75 million zero-exercise-price options as a performance incentive, tied to milestones such as scoping and pre-feasibility studies, continued service and share price hurdles. As the rare earths race heats up globally, Critica's board is betting that with Deysel's leadership, Jupiter might just become one of the world's great rare earth mines - right in Western Australia's backyard.
