NevGold Corp.  (TSX-V:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce further positive oxide antimony-gold drill results at its Limousine Butte Project in Nevada. The Company is also pleased to announce the initial antimony-gold Mineral Resource Estimate is on schedule for Q2-2026. The MRE is a key step in the development of Limo Butte with the objective of achieving near-term antimony production from the historical gold leach pads at the Project.

NevGold CEO, Brandon Bonifacio, comments: “We continue to validate that we have one of the highest grade antimony projects in North America that is near-surface and oxide, which is exemplified by Hole LB25-024 which intercepted a thick, consistent zone of 4.91 g/t AuEq* over 27.4 meters (1.09% Sb and 0.67 g/t Au). Most of the global antimony projects are sulphide and narrow vein-type systems that require underground mining to produce an antimony concentrate, which adds significant complexities to the operation, cost structure, and concentrate marketing. At Limo Butte we have defined a large, near-surface footprint of oxide antimony mineralization which is amenable to leaching, and we have the opportunity to produce antimony metal at the project site. Being able to produce antimony metal at the project site removes reliance on downstream refining at a concentrator.”

Bonifacio continues: “Our initial antimony-gold Mineral Resource Estimate is on track for Q2-2026, which will allow us to highlight the key at tributes of the Project. We are in an advantageous position as we have development optionality as we advance Limo Butte towards a potential production and cash-flow scenario by 2027, with further phased gold-antimony project development scenarios in the future. All of our various work programs have demonstrated the quality of the antimony-gold potential at Limo Butte, and we will continue to systematically advance the Project with the objective of playing a key part in the mandate to create a vertically integrated, U.S. antimony supply chain.”

Key Highlights

• High-grade oxide antimony-gold intercepted with 11.42 g/t AuEq* over 7.7 meters (2.64% Sb and 1.17 g/t Au):

• • LB25-024 (MRE upgrade, gap in antimony data): 11.42 g/t AuEq* over 7.7 meters (2.64% Sb and 1.17 g/ t Au), within 4.91 g/t AuEq* over 27.4 meters (1.09% Sb and 0.67 g/t Au)

• Further re-assay results from historical drilling have upgraded the geological database for MRE purposes:

• • LB22-025 (MRE upgrade, re-assay result): 5.36 g/t AuEq* over 9.1 meters (1.30% Sb and 0.30 g/t Au), within 1.75 g/t AuEq* over 73.2 meters (0.31% Sb and 0.53 g/t Au)
  • LB21-001 (MRE upgrade, re-assay result): 2.28 g/t AuEq* over 46.8 meters (0.22% Sb and 1.41 g/t Au) including 2.15 g/t AuEq* over 13.7 meters (0.39% Sb and 0.62 g/t Au)
  • *Gold equivalents (“AuEq”) are based on assumed metals prices of US$3,000/oz of gold and US$40,000 per tonne of antimony, and assumed metals recoveries of 80% for gold and 75% for antimony.

• Historical gold leach pad drill program advancing with 15 holes completed of planned approximate 35 hole program (see Figure 3)

• • MRE on historical leach pads is tracking to early Q2-2026
  • MRE on historical leach pads is key step in the development of near-term antimony production scenario at the Project
  • 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 Zo ne discovery made in 2025) and Cadillac Valley providing staged project development

• 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 in the historical leach pads

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).

*Downhole thickness reported; true width varies depending on drill hole dip and is approximately 70% to 90% of downhole thickness.

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 su pply 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. 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 awards, over $1.8 billion in indicative financing from the Export Import Bank of the United States (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 and US$75 million from JPMorganChase’s $1.5 trillion Security and Resiliency Initiative. (see Perpetua Resources News Release from October 27, 2025)
