Nevgold Corp. (‘NevGold’ or the ‘Company’) (TSXV:NAU,OTC:NAUFF) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that the permits have been received and a drill rig is mobilizing to its Limousine Butte Project (the ‘Project’, ‘Limo Butte’) in Nevada. The drilling will test the historical gold heap leach pads for antimony with the objective of advancing the leach pads to a near-term antimony production scenario. This is one of the only near-term, at-surface antimony production scenarios in the United States with a path to potential antimony metal production by 2027. 

NevGold CEO, Brandon Bonifacio, comments: ‘There are very few opportunities like the near-term antimony production potential from the historical gold leach pads at Limo Butte. There is a clear mandate in the United States to find near-term production from a number of Critical Minerals, and we have one of those opportunities which we are rapidly advancing. We are in an advantageous position as we have oxide antimony at surface amendable to leaching at a brownfield mine site in the State of Nevada, which is one of the top mining jurisdictions globally with a systematic permitting regime and strong community support. Our focus is to drill the leach pads to advance to a Mineral Resource Estimate by the beginning of Q2-2026, which will define the grade and quantities of contained antimony that we have on the pads. Once an MRE is delivered, we will be able to evaluate the various development scenarios to extract the antimony from the leach pads, with the objective of reaching antimony metal production by 2027. We have the opportunity to be one of the near-term solutions to the United States building a fully vertically integrated antimony supply chain‘

Key Highlights

• Drilling will advance the leach pads to a Mineral Resource Estimate (‘MRE’) by the beginning of Q2-2026 building on the Phase 1 sampling completed (see News Release from January 6, 2026):

• • The MRE is a key step in defining the quantities of antimony that could be processed in the near-term from the historical gold leach pads
  • Drilling will be completed over the coming weeks
  • Certain areas of the leach pads had Phase I sampling results of 0.74% Sb to 0.81% Sb (See Figure 1)

• • 2025 testwork using acid leaching resulted in antimony recoveries of up to 92%
  • Acid Leaching is being reviewed as the preferred metallurgical process for antimony as there is no reliance on downstream processing at third-party smelters; the acid leaching scenario would produce antimony metal at site through a conventional leaching scenario, which has many similarities to Solvent Extraction-Electrowinning (SX/EW) used for oxide copper in the copper industry
  • Antimony recovery has minimal to no impact on gold recovery; the gold in the historical leach pads could also be recovered in the future after antimony processing is completed

• Antimony is one of the highest priority Critical Minerals due to its strategic importance and military applications; Limo Butte is a brownfield mine site located in the State of Nevada with near-surface, high-grade antimony mineralization

• • Historical leach pads provide opportunity for near-term antimony production
  • A larger commercial gold-antimony opportunity could be advanced and developed in parallel to the historical leach pad opportunity, including drilling, metallurgical testwork, and the preparation of a Mineral Resource Estimate (‘MRE’) at Resurrection Ridge (including high-grade antimony Bullet Zone discovery made in 2025) and Cadillac Valley
  • A staged project development approach offers various potential development scenarios over the next 12-24 months which may achieve near-term production and cash flow

• 30 holes completed in the current 2025-2026 drill program with 12 holes pending release 

Limo Butte Planned 2026 Activities / Status Update
NevGold will continue its active exploration program at Limo Butte including:

• Evaluating the historical geological database with focus on gold and antimony (completed);

• Advancing metallurgical testwork (ongoing);

• Continuing to drill test gold-antimony targets (5,000 meters (30 drillholes) completed, a further 20,000 meters is planned in 2026 focused on the Bullet Zone and Armory Fault discoveries);

• Advancing the Crushed and Run of Mine (‘ROM’) leach pads to near-term antimony production (Drilling March-2026, MRE beginning of Q2-2026, ongoing metallurgical testwork);

• Completing initial gold-antimony Mineral Resource Estimate (MRE) (in progress).

US Executive Order – Announced March 20, 2025
The Company is pleased to report the sweeping Executive Order to strengthen American mineral production and reduce U.S. reliance on foreign nations for its mineral supply. Antimony (Sb) has been identified as an important ‘Critical Mineral’ in the United States essential for national security, clean energy, and technology applications, yet limited domestic mine supply currently exists.

The Executive Order invokes the use of the Defense Production Act as part of a broad United States (‘US’) Government effort to expand domestic minerals production on national security grounds. As it relates to project permitting, the Order states that it will ‘identify priority projects that can be immediately approved or for which permits can be immediately issued, and take all necessary or appropriate actions…to expedite and issue the relevant permits or approvals.’ Furthermore, the Order includes provisions to accelerate access to private and public capital for domestic projects, including the creation of a ‘dedicated mineral and mineral production fund for domestic investments’ under the Development Finance Corporation (‘DFC’).

This decisive action by the US Government highlights the urgent need to expand domestic minerals output to support supply chain security in the United States. This important Order will help revitalize domestic mineral production by improving the permitting process and providing financial support to qualifying domestic projects.

Importance of Antimony
Antimony is considered a ‘Critical Mineral’ by the United States based on the U.S. Geological Survey’s 2022 list (U.S.G.S. (2022)). ‘Critical Minerals’ are metals and non-metals essential to the economy and national security. Antimony is utilized in all manners of military applications, including the manufacturing of armor piercing bullets, night vision goggles, infrared sensors, precision optics, laser sighting, explosive formulations, hardened lead for bullets and shrapnel, ammunition primers, tracer ammunition, nuclear weapons and production, tritium production, flares, military clothing, and communication equipment. Other uses include technology (semi-conductors, circuit boards, electric switches, fluorescent lighting, high quality clear glass and lithium-ion batteries) and clean-energy storage.

Globally, approximately 90% of the world’s current antimony supply is produced by China, Russia, and Tajikistan. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, announced that it will restrict antimony exports. In December-2024, China explicitly restricted antimony exports to the United States citing its dual military and civilian uses, which further exacerbated global supply chain concerns. (Lv, A. and Munroe, T. (2024)) The U.S. Department of Defense (‘DOD’) has designated antimony as a ‘Critical Mineral’ due to its importance in national security, and governments are now prioritizing domestic production to mitigate supply chain disruptions. Projects exploring antimony sources in North America play a key role in addressing these challenges.

Perpetua Resources Corp. (‘Perpetua’, NASDAQ:PPTA, TSX:PPTA) has the most advanced domestic gold-antimony project in the United States. Perpetua’s project, known as Stibnite, is located in Idaho approximately 130 km northeast of NevGold’s Nutmeg Mountain and Zeus projects. Positive advancements at Stibnite including technical development and permitting has led to US$75 million in Department of Defense (‘DOD’) awards, over $1.8 billion in indicative financing from the Export Import Bank of the United States (‘US EXIM’) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025)), and recent strategic investments of US$180 million from Agnico-Eagle Mines Limited (‘Agnico’) and US$75 million from JPMorganChase’s $1.5 trillion Security and Resiliency Initiative.

Tartisan Nickel Corp. (CSE: TN,OTC:TTSRF) (OTCQX: TTSRF) (FSE: 8TA) (‘Tartisan’, or the ‘Company’) is pleased to announce that the Company has acquired four additional claims in the Turtle Pond Area, Northwestern Ontario, approximately 40 km south of Dryden, Ontario. The total property size now consists of 165 staked units covering 3,454 ha. The claims are owned 100% by Tartisan Nickel Corps. wholly owned subsidiary Canadian Arrow Mines Limited.

The claims are located approximately 70 kms east of the Company’s flagship Kenbridge Nickel Deposit. The property is situated in an area of excellent infrastructure and consists of 165 claim units and hosts the historical Glatz, Double E and Night Danger nickel-copper showings.

Previous exploration efforts identified nickel-copper sulphide mineralization in twelve trenches along a 700 metre trend at the Glatz nickel copper showing. The zone, discovered in 1965 by local prospector A. Glatz, is up to 40 metres wide and is open along strike and at depth. Historical grab samples were reported to contain up to 1.95% Ni. In 2007, Canadian Arrow Mines Limited. conducted a surface grab sampling program which produced the following results: 1.28% Ni, 0.26% Cu re Glatz Trench 3; 0.99% Ni, 0.18% Cu re Glatz Trench 3; 0.39% Ni, 4.06% Cu re Trench 4. The mineralization varies from disseminated sulphides to narrow semi-massive sulphide bands. Six short drill holes were completed at that time with hole GZ-09-02 encountering 0.34% Ni, 0.16% Cu and 0.02% Co over 5.9 m from 45.0-50.9 m.

A nickel-copper-PGE discovery on the Double E airborne VTEM anomaly was identified in 2008. The drilling intersected two separate upper and lower mineralized zones in 2 drill holes. Hole EE-09-02 intersected 4.2 metres of 0.81% Ni, 0.52% Cu, 0.20gpt Pt, 0.16gpt P and 0.20gpt Au at a depth of 25.5 metres. This included 2 metres of 1.35% Ni, 0.81% Cu, 0.36gpt Pt, 0.27gpt Pd and 0.31gpt Au. A second zone was intersected at a depth of 135.1 metres containing 8.2m of 0.55% Ni and 0.38% Cu. Hole EE-l0-04 intersected 1.9 metres of 0.51% Ni, 0.24% Cu at a depth of 21.4 metres and a second narrow intersection of 1.9 metres of 0.52% Ni, 0.28% Cu at a depth of 28 metres.

Exploration diamond drilling work completed in 2009 and 2010 on the Night Danger nickel-copper intercepts and reported a nine-metre-wide section of stringers and blebs of sulphide which assayed 0.57% Ni and 0.45% Cu at a drill depth of 79m in hole ND-09-1. Two sections within this interval assayed greater than 1% nickel. Drill hole ND-10-1 intersected 4.53% Ni over 0.7m at a drill depth of 57.5m (Source; MNDM assessment files and Canadian Arrow Mines Limited news release dated June 1, 2010, SEDAR).

From November 28^th to December 21^st, 2024, a TDEM Geophysical survey was performed on the Turtle Pond Lake Property and was undertaken by Expert Geophysics Limited. Tartisan Nickel Corp. requested this survey for the purpose of determining drill targets and potential future exploration work on The Property.

Mark Appleby, President and CEO of Tartisan stated, ‘The Glatz, Double E and Night Danger nickel-copper showings display similar nickel and copper tenors as what we find near surface at our Kenbridge Nickel Deposit. Acquisition of these additional claims not only shows but also complement the company’s larger objective of developing the Kenbridge Project into a much larger area play. The Company will be formulating an exploration program consisting of surface sampling and potentially diamond drilling in 2026-27.’

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) (‘Homerun’ or the ‘Company’) is pleased to announce that researchers at the University of California, Davis (‘UC Davis’), in collaboration with Homerun, have successfully produced fused silica glass from raw silica sand using a one-step thermoelectric Fast Joule Heating (‘FJH’) process. These tests demonstrate, at bench scale, that silica from Homerun’s Santa Maria Eterna (SME) Silica Sand Project can be converted directly into fused silica glass without chemical reagents, supporting the Company’s strategy to supply high-value advanced materials markets.

Building upon the prior test work completed by independent materials consultancy Dorfner Anzaplan (see news release), which confirmed that the raw SME silica sand is suitable as feedstock for fused silica production using conventional multi-step processing methods, Homerun and UC Davis specifically set out to evaluate whether that same material could be processed to fused silica glass using new, more efficient one-step thermoelectric processing techniques. The UC Davis testing has now produced fused silica glass.

The issue confronting wider adoption of high-purity fused silica across high volume traditional and novel end-uses is the limited supply and high price due to the cost of conventional processing techniques.

A conductive material (here carbon black) is sandwiched between graphite plugs and undergo a rapid heating process as a charged voltage is released from the capacitor. This entire setup is enclosed within a vacuum-sealed chamber, which can be purged and filled with various gases to enable controlled atmospheric environments.

Subhash Risbud, Director of the Risbud Research Group at UC Davis, stated, ‘Critical to the success of our FJH process was incorporating a conductive medium for the current to flow while yet keeping the silica powder separated. Thus, we developed a new tube-within-tube configuration in which silica is confined to the inner tube while the outer tube contains the conductive substrate (graphite). This approach helps sustain the high temperatures required for extended processing. Based on our results, the silica to fused silica glass synthesis has worked using our FJH equipment (as shown in Figure 1). Fused silica glass was achieved very rapidly after our processing peak temperature reached about 2000 C (above the 1710 C melting point of silica). These exciting new results in processing to fused silica glass using Flash Joule Heating are reported as part of the continuing collaborative research being conducted by the Risbud Research Group at UC Davis and adds to previous new laser-based techniques developed in the same lab for the purification of the SME silica sand, all under the continuing funding from Homerun.’

‘Utilizing the Fast Joule Heating method to process a raw silica sample from the Homerun SME Silica Sand Project into fused silica glass is a big step in our advanced materials development,’ stated Brian Leeners, CEO of Homerun. ‘The FJH method does not use any chemical reagents and therefore generates no polluting waste stream. If the energy source is renewable, then this is a completely green process. We chose FJH for this testing as it has been scaled utilizing off-the-shelf equipment in other critical materials processing. These techniques, after the necessary improvements, can produce fused silica glass used for medical, pharmaceutical, electronics, photonics and other similar technology and energy applications.’

The next step in the Homerun / UC Davis testing plan is to incorporate off-the-shelf equipment to begin scaling the production capacity of the fused silica glass using FJH. This testing was initiated immediately after the successful bench testing.

Fused silica tech markets are dominated by semiconductor fabrication, high-performance optics, and advanced electronics, driven by its extreme purity, thermal stability, and optical clarity. Key applications include lithography lenses, wafer substrates, fiber optics, and laser systems, with growing demand from 5G, IoT, and long-term data storage. Ultra-pure fused silica also serves as a high-performance, low-loss substrate for superconducting qubits and as a base material for silicon-based, spin-qubit quantum computers.

Nvidia recently announced a combined investment of US$4 billion into two photonics companies, Lumentum and Coherent to advance photonics technology for AI data centers. The multiyear agreements include purchase commitments and capacity access for advanced optical networking products, supporting U.S.-based manufacturing and R&D. The move targets performance and efficiency gains in AI systems by enhancing data transfer capabilities using photonics.

Photonics uses light instead of electrical signals through copper, enabling faster and more energy-efficient data transfer. Nvidia’s adoption of co-packaged optics in Spectrum and Quantum switches removes the need for pluggable modules on the switch side, cutting hardware requirements and power consumption. This technology is essential for connecting multiple AI systems or data centers over extended distances. Nvidia success could lead to direct integration of photonics into Nvidia’s GPUs, boosting AI training speed and efficiency. Alternatively, faster innovation from competitors such as Amazon or Google could challenge Nvidia’s position. Control over photonics supply might also lengthen lead times for rivals, reshaping the competitive dynamics in the optics market.

‘NVIDIA is advancing the world’s most sophisticated silicon photonics to build the next generation of gigawatt-scale AI factories.’

NEW PATENT APPLICATION ADDED TO PATENT PORTFOLIO

Homerun also announces that a new patent application has been filed for an invention resulting under the Company’s partnership with UC Davis. The invention relates to a:

‘PROCESS FOR OBTAINING HIGH-PURITY SILICA SAND AND THE RESULTING PRODUCT.’

The invention describes a novel, environmentally friendly process for purifying silica sand to ultra-high purity levels, primarily targeting industrial applications such as semiconductors, LCDs, and optical glass. The process leverages femtosecond laser ablation, which eliminates the need for hazardous chemicals and energy-intensive mechanical methods traditionally used in silica purification.

Key Steps in the Process: Grinding, Vacuum, Laser Treatment and analysis.

Results and Advantages:

• Purity Improvement: The analysis shows a significant reduction in impurities (Ti, Ca, Mg, Fe), with purity increasing from 99.75% to +99.99%.

• Environmental Benefits: The process avoids hazardous chemicals and reduces energy consumption compared to conventional methods.

• Industrial Relevance: The resulting high-purity quartz silica sand (HPQ) is suitable for demanding industrial uses.

The above UC Davis fused silica glass testing results have not been independently verified and may also be the subject of a future Homerun Patent Application.
