” or the “ ”) ) is pleased to announce the discovery of high-grade oxide antimony in the new antimony-gold from surface at its Limousine Butte Project (the “Project”, “Limo Butte”) in Nevada. The Bullet Zone was discovered with a plus 150 meter step-out drillhole from 2025 drilling that was testing NevGold’s new geology model at the Project. The Bullet Zone discovery significantly expands the gold-antimony mineralization footprint at the Resurrection Ridge target area, which NevGold is advancing to an initial gold-antimony Mineral Resource Estimate (“MRE”).

NevGold will continue its active exploration program at Limo Butte including:

The (“Pilot Shale”, “Pilot”) is the principal local host to Carlin-type mineralization at Limousine Butte. At Limousine Butte, positive gold grades commonly coincide with within the Pilot Shale, an alteration style also observed where elevated antimony is reported.

NevGold’s 2021–2025 work included integrating historical drilling, new mapping, and surface sampling which produced an updated district model and refined property-wide controls on mineralization. At , Devonian–Silurian is exposed immediately east of known gold-antimony mineralization. Earlier explorers inferred that the overlying Pilot Shale had been eroded in this area, and they did not test eastward, despite shallow high-grade intercepts in the easternmost holes drilled at Resurrection Ridge. The new model indicates the older dolomite was the prospective Pilot Shale unit, creating structural preparation and a fluid trap that preserves the favorable host at depth, the classic architecture for a Carlin-type system.

Hole , the first test of this new NevGold geological model, collared in dolomite, passed through the upper thrust plate, and intersected at multiple horizons within the Pilot Shale. This drillhole result validates the model and materially expands the potential mineralization footprint: the preserved Pilot Shale extends of prior drilling at Resurrection Ridge.

Property-wide, the updated model outlines multiple target corridors that track outcrops and projected subsurface positions of the Pilot Shale, where repeated provided fluid pathways and focused mineralization. NevGold’s 2025 drill program continues to test these high-priority targets.

Historical records within the project boundary document two small-scale antimony prospects—the and the (Figure 1). The Nevada Antimony Mine extracted from a hydrothermal breccia via shallow pits; the Lage prospect similarly reports limited antimony production. Complementing these records, rock-chip sampling from the pit (Brigham Young University thesis) returned numerous assays exceeding in jasperoid breccias, with several over , including a sample grading with visible stibnite and stibiconite ( ).

Together, these datasets support a district-scale interpretation in which and focuses Au–Sb mineralization along structurally prepared horizons, establishing multiple high-priority targets for step-out drilling and follow-up work.

The Company is pleased to report the sweeping . Antimony (Sb) has been identified as an important essential for national security, clean energy, and technology applications,

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.

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”) 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 the technical development and permitting has led to US$75 million in Department of Defense (“DOD”) awards, and over $1.8 billion in indicative financing from the Export Import Bank of the United States (“US EXIM”) ( ) (Perpetua Resources. (2025))

NevGold QA/QC protocols are followed on the Project and include insertion of duplicate, blank and standard samples in all drill holes. A 30g gold fire assay and multi-elemental analysis ICP-OES method was completed by ISO 17025 certified American Assay Labs, Reno.

The historic data collection chain of custody procedures and analytical results by previous operators appear adequate and were completed to industry standard practices. For the Newmont and US Gold data a 30g gold fire assay and multi-elemental analysis ICP-OES method MS-41 was completed by ISO 17025 certified ALS Chemex, Reno or Elko Nevada.

Geochemical ICP (5g) analysis for the Wilson, Christianson and Tingey report was completed by Geochemical Services Inc. and the XRF analyses (glass disk or pellets) by Brigham Young University.
