(TheNewswire)

Vancouver, British Columbia, November 5th, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘ ) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that Walnut Mines LLC, the owner of the Hot Breccia claims optioned as to 75% by the Company, has agreed to extend certain dates to complete cash payments and exploration expenditures.

Alain Lambert, CEO of Prismo said: ” Prismo remains firmly committed to advancing the Hot Breccia Project, located in the heart of Arizona ‘ s historic copper belt. We appreciate the cooperation of Walnut Mines LLC in extending certain milestone obligations, which provides the Company with additional flexibility as we assess a range of strategic alternatives. Each of these paths is designed to position Prismo to commence drilling on what we consider one of the most compelling copper exploration opportunities in Arizona and the broader United States. ‘

Dr Linus Keating, manager of Walnut Mines LLC, enthusiastically commented: ‘Walnut and Prismo remain firmly dedicated to advancing Hot Breccia towards drill discovery. Accomplishing that goal requires that we continue to work together and support each other. This extension will provide the necessary time, and better focus resources, to succeed at Hot Breccia.’

More specifically, the extensions are as follows: (i) extend the milestone date to complete exploration expenditures of $1,750,000 from January 31, 2026 to January 31, 2027; and (ii) extend the milestone date to complete exploration expenditures of $2,000,000 from January 31, 2027 to January 31, 2028 and (iii) extend the milestone date to complete the final cash payment of $275,000 to Walnut Mines LLC from January 31, 2026 to July 31, 2026.

Prismo ‘ s Hot Breccia project lies at the heart of the Arizona Copper Belt, which hosts several globally significant porphyry copper deposits.  Examples of these significant deposits are Freeport McMoRan’s Miami-Inspiration mining complex, BHP’s San Manuel mine, Rio Tinto and BHP’s Resolution deposit and others (see Figure 1).

Figure 1. Location of the Hot Breccia Project in the Arizona Copper Belt.

Historical drilling carried out in the mid to late 1970 ‘ s by a Rio Tinto subsidiary intersected high-grade copper mineralization at depths ranging from 640 to 830 meters below surface. Several holes targeted an area with a coincident magnetic high, believed to be caused by magnetite skarn that was cut in the drill holes and that occurs in xenoliths in cross cutting dikes exposed at the surface. Prismo believes those intercepts may represent the periphery of the upper portion of a large mineralized system.

Support for the Company ‘ s mineralization model at the project comes from several sources, including the results of historical drilling, geophysical surveys, distribution of dikes with xenoliths of Cu-bearing skarn, the 2023 ZTEM survey as well as the results of an AI study. The anomalous target area identified in Prismo ‘ s modelling measures 1,100 meters by 1,150 meters.

Dr. Craig Gibson, Chief Exploration Officer of Prismo stated: ‘ The copper exploration target at Hot Breccia has geophysical, geochemical and geological features characteristic of many porphyry copper deposits. The project area has a regional setting similar to BHP-Rio Tinto’s Resolution copper deposit located 40 kilometers to the northwest of Hot Breccia and which is considered to be one on the greatest copper discoveries in the history of North American mining. ‘ He added: ‘ The drill program is intended to drill through the entire prospective Paleozoic carbonate stratigraphy into the postulated porphyry body/breccia zone. The exploration team will take advantage of geological information provided by each hole during drilling to refine targeting of subsequent holes. ‘

Historical drill holes cut high grade skarn mineralization including 23 meters with 0.54% Cu at 640 meters depth (hole OC-1), 18 m with 1.4% Cu and 4.65% Zn at 830 meters depth (hole OCC-7), and 7.6 m with 1.73% Cu and 0.11% Zn at 703 meters and 4.6 meters with 1.4% Cu and 0.88% Zn at 716 meters (OCC-8).  Mineralization occurs within a several hundred-meter-thick altered zone hosted in favorable Paleozoic carbonate rocks that underly a sequence of Cretaceous andesitic volcanic rocks. These carbonates are the same rocks that host the high-grade copper mineralization at Freeport ‘ s nearby Christmas mine.  The historic drilling intersected a blind mineralized intrusion associated with the skarn mineralization, providing an immediate drill target that is believed to be the source of the mineralization at Hot Breccia (Figure 2). Several magnetic highs in the region surrounding the proposed intrusion may also indicated buried skarn mineralization and provide additional exploration targets.

About Hot Breccia

The Hot Breccia property consists of 1,420 hectares in 227 contiguous mining claims located in the world class Arizona Copper Belt between several very well understood world-class copper mines including Morenci, Ray and Resolution (Figure 1). Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth. Prismo performed a ZTEM survey last year that identified a very large conductive anomaly directly beneath the breccia outcrops.

Sampling at the project has shown the presence of copper mineralization associated with dacite dikes that transported fragments of strongly mineralized carbonate rocks to the surface from depths believed to be 400-1,000 meters. Drilling deep holes is necessary to tap into the source of these mineralized fragments found at surface.

Assay results from historic drill holes are unverified as the core has been destroyed, but information has been gathered from memos, photos and drill logs that contain some, but not all, of the assay results and descriptions.  Technical information from adjacent or nearby properties does not mean nor does it imply that Prismo will obtain similar results from its own properties.

Data on previous drilling and geophysics is historical in nature and has not been verified, is not compliant with NI 43-101 standards and should not be relied upon; the Company is using the information only as a guide to aid in exploration planning.

Perth, Australia (ABN Newswire) – Locksley Resources Limited (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) announced that it has entered a non-binding Memorandum of Understanding (MoU) with Hazen Research Inc. a leading metallurgical processing provider, to formulate an agreement for toll processing of ore from Locksley’s Desert Antimony Mine in the United States.

HIGHLIGHTS

– Accelerates 100% U.S. Mine-to-Market Supply by establishing a scalable processing pathway to deliver American sourced and manufactured Antimony products to market

– Secures immediate processing capacity through a Tier 1 U.S. metallurgical and defence materials processing provider (Hazen Research Inc.)

– Advances key studies, including pilot plant design, commercial analysis and toll processing, supported by Rice University’s antimony processing research

– Produces representative product samples for qualification with U.S. industrial and defense off-takers, strengthening Locksley’s position as building a fully integrated, American sourced antimony supply chain, supported by EXIM and U.S. processing partnerships

– Engagement with Hazen Research Inc. supports U.S. government objectives to rebuild domestic critical minerals processing, aligning Locksley with White House and Department of Defense priorities for restoring American antimony production

This agreement provides a pathway to secure immediate processing capacity while pilot plant design, construction and associated commercial scale development studies continue concurrently.

The MoU provides a framework for cooperation on the following key operational workstreams:

– Validate process performance and recovery efficiency under semi-continuous or batch operating conditions

– Confirm metallurgical response and optimization of process parameters

– Generate representative product samples for chemical, physical, and environmental characterization

– Produce data to support the design criteria and economic evaluation for future pilot or commercial scale operations

– Toll treatment of ore during the ongoing pilot and commercial plant development phases

The execution of this MoU is aligned with the Company’s strategy to accelerate production timelines, de-risk early processing operations and advance the project toward commercialisation.

Danny George, COO of Locksley, commented:

‘We are pleased to formalise this MoU with Hazen Research Inc. after our recent collaboration casting a 100% American made ingot. This MoU represents an important step in de-risking our ore processing strategy and accelerating the path to revenue. By securing toll processing capacity in the United States, we can begin generating operational data and product while our pilot and commercial-scale plant development continues in parallel.

This approach allows us to maintain project momentum, optimise metallurgical performance, and provide early market supply, positioning the Company to deliver value to shareholders efficiently and safely. We look forward to working closely with Hazen Research Inc. as we progress towards full commercial operations. The U.S. Government’s clear prioritisation of domestic critical mineral production provides a strong backdrop for our accelerated execution. We are advancing with the right partners, the right timing and clear commercial intent.’

Advancing Multiple Concurrent Workstreams to Steady State Production

With successful validation of the 100% American made antimony ingot, as part of our execution strategy, Locksley Resources will now advance concurrent workstreams toward production, including toll processing, starter plant and commercial plant development.

Further to this, the Company’s executive team recently engaged in-person with U.S based Tier 1 engineering firms, EPCM contractors and execution partners to progress its project delivery strategy.

Concurrently with the toll production operation, the Company is also actively advancing the pilot/starter plant development, informed by the results of ongoing metallurgical test work.

These parallel workstreams are intended to accelerate the transition from pilot scale operations to commercial production, de-risking the development pathway and providing early operational insights to optimise future plant performance. This next phase will support offtake readiness and qualification for domestic supply contracts, further positioning Locksley as a pioneer in restoring America’s antimony production and processing capability.

The Company’s collaboration with Rice University continues in parallel, supporting the optimisation of hydrometallurgical extraction parameters and the development of antimony-based materials. Locksley’s Mojave Project represents one of the few known high-grade, primary antimony deposits located in continental U.S., offering a rapid path to production and a strategic alternative to Chinese controlled supply chains.

Next Steps:

The parties will now progress discussions to formalise definitive agreements for toll processing, with the aim of commencing operations in line with the project development schedule. With government backed financing, strategic U.S. processing partnerships with Hazen and Rice University, and a rapid development pathway in motion, Locksley is entering its most transformative phase. The Company is uniquely positioned to deliver one of the first fully American sourced antimony supply chains, advancing from mine validation to market readiness within an accelerated timeline.

About Locksley Resources Limited:

Locksley Resources Limited (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) is an ASX listed explorer focused on critical minerals in the United States of America. The Company is actively advancing exploration across two key assets: the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley Resources aims to generate shareholder value through strategic exploration, discovery and development in this highly prospective mineral region.

Mojave Project

Located in the Mojave Desert, California, the Mojave Project comprises over 250 claims across two contiguous prospect areas, namely, the North Block/Northeast Block and the El Campo Prospect. The North Block directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials’ claims, highlighting the strong geological continuity and exploration potential of the project area.

In addition to rare earths, the Mojave Project hosts the historic ‘Desert Antimony Mine’, which last operated in 1937. Despite the United States currently having no domestic antimony production, demand for the metal remains high due to its essential role in defense systems, semiconductors, and metal alloys. With significant surface sample results, the Desert Mine prospect represents one of the highest-grade known antimony occurrences in the U.S.

Locksley’s North American position is further strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE & antimony production. With its maiden drilling program planned, the Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security.

Perth, Australia (ABN Newswire) – Red Mountain Mining Limited (ASX:RMX) (OTCMKTS:RMXFF), a Critical Minerals exploration and development company with active projects in Tier-1 Mining Districts in the United States and Australia, has announced the Company’s advanced progression towards a US Stock Exchange listing.

HIGHLIGHTS

– Red Mountain Mining has recently appointed a highly regarded US-based markets advisory team and is in the final stages of confirming a US Stock Market listing on the OTCQB under the US Stock Code ‘RMXFF’

– In 2024, over US$478 billion (AU$732 billion) in liquidity and volume flowed through the United States OTC Markets Group’s exchanges

– Red Mountain has secured multiple US antimony assets in Tier-1 mining districts since mid September 2025, with projects located adjacent to high value, major Antimony projects, including Perpetua Resources’ (NASDAQ:PPTA) Stibnite Project in Idaho and Trigg Minerals’ (ASX:TMG) Antimony Canyon Project in Utah

– Red Mountain has also made significant progress at its Armidale Antimony-Gold Project in the New England Orogen in New South Wales, the location of Larvotto Resources’ (ASX:LRV) Hillgrove project, which is Australia’s largest Antimony deposit and the target of a recent acquisition proposal by United States Antimony Corporation (NYSE:UAMY)

– Following highly encouraging inbound interest received from several US investment banks, the Red Mountain Board believes the planned US Stock Market listing provides a series of value accretive opportunities including:

o Providing US retail and institutional investors direct access to invest and trade in the Company’s shares on the OTCQB under the US Stock Code ‘RMXFF’

o Positioning RMXFF alongside US peers in the critical minerals sector, potentially further improving valuation metrics and attracting specialised US resources investors

o Improving Red Mountain’s current strong strategic alignment with the US Government’s dramatic push to secure a domestic supply of critical minerals, and better positioning the Company to benefit from strong US Federal financial support for critical mineral projects targeting antimony

– Red Mountain expects to confirm the ‘RMXFF’ listing date by next week

Red Mountain has recently appointed its US-based markets advisory team and is in the final stages of confirming a US Stock Market listing on the OTCQB under the US Stock Code ‘RMXFF’. Since mid-September 2025, Red Mountain has pursued an aggressive acquisition strategy, securing three US antimony assets in Tier-1 mining districts since mid-September 2025, with projects located adjacent to high value, major antimony projects, including Perpetua Resources’ (NASDAQ:PPTA) Stibnite Project in Idaho and Trigg Minerals’ (ASX:TMG) Antimony Canyon Project in Utah.

RMX has also made significant progress during 2025 within its Armidale Antimony-Gold Project in the New England Orogen in New South Wales, by demonstrating high-grade orogenic antimony mineralisation with associated gold at multiple prospects. RMX’s project hosts a similar style of mineralisation and is located within the same prospective geological province as of Larvotto Resources’ (ASX:LRV) (A$540m market cap) Hillgrove project, which is Australia’s largest Antimony deposit and the target of a recent acquisition proposal by United States Antimony Corporation (NYSE:UAMY) (A$1.5b market cap.).

US Government focused on building domestic Antimony supply

Presently, about 90% of global antimony production is controlled by China, Russia, and Tajikistan, which is creating significant supply risks for Western nations such as Australia and the US. Both countries currently have no producing antimony mines, despite the metal’s critical role in defence applications, including armament manufacture and semiconductor technologies. With China’s current export ban creating acute supply shortages and the antimony price recently reaching US$60,000 per tonne, the US Government has issued emergency declarations and mobilised unprecedented funding for domestic production.

The majority of the available US Federal funding is being directed under White House led initiatives and includes opportunities such as:

– The Export-Import Bank (EXIM) Supply Chain Resiliency Initiative (SCRI), which will provide financing for international projects with signed long-term ‘off-take’ contracts with U.S. companies, providing these U.S. companies with access to critical minerals from partner countries.

– EXIM’s China and Transformational Exports Program (CTEP), which provides funding in strategic sectors like critical minerals to support American companies in projects that might otherwise be lost to China, aligning with the U.S.’s broader goals to boost supply chain resilience and national economic competitiveness.

– Defense Production Act Title III funding for strategic materials, which partners with U.S. private industry to mitigate gaps in the domestic supply chain through the use of grants, purchase commitments, loans, or loan guarantees.

An indication of the potential level of investment available to high quality projects is demonstrated by Locksley Resources’ (ASX:LKY,OTC:LKYRF) announcement this week that it had secured a Letter of Interest from EXIM indicating potential financing support of up to US$191 million for Locksley’s Mojave Antimony-REE Project in California.

On 21 October, the US President and Australian Prime Minister executed a Critical Minerals Framework agreement, through which the two governments have committed to spend at least US$1 billion each in the next six months as direct investment into a pipeline of critical minerals projects in in the US and Australia.

EXIM has also partnered with Export Finance Australia (EFA), to establish a streamlined pathway for businesses to approach both agencies and enable faster referrals and joint financing of eligible critical mineral transactions, known as the Single Point of Entry. Through this agreement, US and Australian businesses may now approach either EXIM or EFA and will receive streamlined access to both agencies’ financing support.

Red Mountain is already well placed to respond to these opportunities through continued successful progression of the Armidale Antimony-Gold Project, rapid exploration of three recently acquired highly prospective antimony-gold projects in Utah and Idaho, USA, and planned additional US antimony projects currently under consideration for acquisition. The Board strongly believes that the Company’s US Stock Market listing will provide Red Mountain with increased visibility to specialised US resources investors and provide a strong platform to directly benefit from US Federal financial support for critical mineral projects targeting antimony.

Red Mountain Utah Antimony Project, USA

In September, Red Mountain announced the acquisition of 87 claims within the Antimony Mining district east of the town of Antimony, Utah, USA. The Antimony Mining district was discovered in 1879 and produced high-grade Sb ores from multiple small-scale mines from 1880 to about 1908 and intermittently into the 1960s. RMX’s claims lie immediately along strike to the north and south of Trigg Minerals’ (ASX:TMG) Antimony Canyon Project (Figure 1*), which includes more than 30 small historical mine workings surrounding both Antimony Canyon and Drywash Canyon, approximately 6km north of the main prospect.

Antimony Mining District – Antimony Mineralisation

Antimony mineralisation within the Antimony Mining district is related to an approximately northsouth trending fault system, which is interpreted to represent fault splays related to the Paunsaugunt Fault. These faults are thought to have provided pathways for hydrothermal fluids from nearby volcanic centres to migrate upward towards favourable stratigraphic horizons, where antimony typically occurs as stibnite veins and stockwork zones sub-parallel to flat-lying stratigraphy. The dominant host for mineralisation at Antimony Canyon and Drywash Canyon is the Early Palaeocene Flagstaff Formation, which comprises carbonate-rich fluvial sandstone and conglomerate, with TMG’s recent exploration concluding that a brittle felsic volcaniclastic horizon within the Formation is the most prospective host unit, but that mineralisation is present at multiple stratigraphic levels, implying potential for both laterally and vertically extensive mineralisation. Channel sampling within and adjacent to historical workings by TMG at Antimony Canyon and Drywash Canyon delivered multiple samples with antimony contents in excess of 10% Sb and a best result of 1.5m at 33.2% Sbfrom the Stebenite Mine in Antimony Canyon.

Antimony Canyon and Drywash Canyon represent two eroded windows into the Flagstaff Formation through a thin (interpreted to be mostly <20m thick), but laterally extensive blanket of Quarternary alluvial and colluvial sedimentary cover (Figure 1*). However, north-south trending faults that provide fluid conduits for antimony-rich mineralising fluids and the Flagstaff Formation host stratigraphy are interpreted to extend beneath the Quaternary cover and into RMX’s tenements. RMX therefore believes that our Utah Antimony Project has high potential for discovery similar mineralisation to that seen at Antimony Canyon and Drywash Canyon.

Red Mountain Yellow Pine Antimony Project, Idaho, USA

In September, Red Mountain announced the acquisition of 29 claims, less than 2km southwest of Perpetua Resources’ (NASDAQ:PPTA) (TSE:PPTA) Stibnite Gold-Antimony Project in central Idaho, USA.

RMX’s Yellow Pine Antimony Project (Figure 2*) is located within the Stibnite Mining District, which was a major source of antimony in the first half of the 20th Century. Recorded production from the Yellow Pine and Hangar Flats deposits between 1932 and 1952 totalled 39,930 tonnes of Antimony.

These two deposits and the West End Deposit, which produced gold and silver from 1978 to 1997, collectively comprise the Proven and Probable Reserve of 104 Mt @ 1.33g/t Au and 0.06% Sb for 4.8Moz Au and 148Mlbs Sb for Perpetua’s Stibnite Project, which is the largest known antimony deposit in the USA. The rich endowment and exploration potential of the Stibnite District has also been recognised by Resolution Minerals (ASX:RML), whose Horse Heaven Antimony Project lies immediately west of Perpetua’s claims and approximately 5km north of RMX’s project area.

Antimony-gold-tungsten mineralisation in the Stibnite Mineral District

Antimony-gold-tungsten mineralisation in the Stibnite Mining District is structurally controlled along early Tertiary north-south striking regional scale faults and smaller northeast-striking splays and is hosted in the Cretaceous granitoids of the Idaho Batholith and adjacent Neoproterozoic to Paleozoic metasedimentary roof pendant rocks (Gillerman et al., 1992).

2017 geological mapping by the Idaho Geological Survey shows that RMX’s claims feature similar prospective geology to that seen within the Perpetua Resources’ Stibnite Project area, with folded Ordovician to Cambrian metasediments intruded by Idaho Batholith granite and cut by a major NNE trending Tertiary fault, with associated tectonic brecciation and evidence of historical small-scale mining activity (Figure 3*).

There is no evidence of modern exploration activity within RMX’s claims. However, reconnaissance mapping by RMX’s field crew has confirmed the presence of tectonic breccias within quartzite associated with the main NNE-trending fault (Figure 3*), which indicates that hydrothermal fluid circulation occurred along the structure. Red Mountain geologists also successfully located the two eastern historical workings mapped by the Idaho Geological Survey, which are small shallow pits that appear to be targeting brecciated quartz veins, most likely seeking gold and/or antimony.

Red Mountain Silver Dollar Antimony Project, Idaho, USA

In October, Red Mountain announced the acquisition of a further claims in central Idaho, covering 2 km2 with demonstrated historical antimony production. The Silver Dollar Antimony Project lies approximately 75km southeast of both RMX’s Yellow Pine Antimony Project, and Perpetua Resources’ Stibnite Gold-Antimony Project.

RMX’s Silver Dollar claims encompass four known alluvial gold and two antimony mineral occurrences, including the Silver Dollar Mine (Figure 4*), which features a 10m deep shaft sunk into fractured granodiorite in 1944, targeting a massive stibnite vein up to 1m thick.

Choate (1962) concluded that there was significant untested potential remaining for additional antimony, gold, silver, uranium and possibly mercury mineralisation, which is likely to occur as pods or shoots where secondary structures intersect each other and the main NNE-striking fault that cuts RMX’s Silver Dollar claims. To RMX’s knowledge, there has been no exploration over the prospect subsequent to Choate’s assessment.

Red Mountain Armidale Antimony-Gold Project, New South Wales, Australia

During 2025, Red Mountain has demonstrated high-grade orogenic antimony mineralisation with associated gold at multiple prospects within the Company’s Armidale Antimony-Gold Project (EL9732) in the Southern New England Orogen (SNEO) of northeast New South Wales, by demonstrating highgrade orogenic antimony mineralisation with associated gold at multiple prospects The SNEO is widely recognised as Australia’s premier antimony province, with 250 antimony mineral occurrences identified in the Geological Survey of NSW mineral occurrence database (Figure 5*).

Antimony occurs in hydrothermal quartz veins, breccias and stockworks, often with associated gold and/or tungsten mineralisation.

Red Mountain continues aggressive acquisition strategy

Red Mountain continues to aggressively seek further opportunities to expand its portfolio of high quality antimony projects in Tier 1 US mining jurisdictions, with a goal of building a portfolio of assets to leverage what is an unprecedented critical shortage of Western supply of the metal. Subject to the satisfactory completion of due diligence, the Company expects to announce further highly prospective acquisition/s in the near term.
