NevGold Releases Some of the Highest Grade Oxide Gold-Antimony Results To Date: 9.68 g/t AuEq Over 11.6 Meters (8.92 g/t Au And 0.17% Antimony) Within 2.85 g/t AuEq Over 60.3 Meters (2.27 g/t Au And 0.13% Antimony) at the Limousine Butte Project, Nevada

Rhea-AI Summary

NevGold Corp. (OTCQX:NAUFF) has announced significant oxide gold-antimony drill results at its Limousine Butte Project in Nevada. The company reported exceptional results including 9.68 g/t AuEq over 11.6 meters within 2.85 g/t AuEq over 60.3 meters at Resurrection Ridge.

The project shows strong potential for an initial gold-antimony Mineral Resource Estimate in 2025. NevGold plans to continue its exploration program, including evaluating historical data, advancing metallurgical testwork, and drill testing gold-antimony targets starting in July.

The announcement is particularly significant given the recent US Executive Order to strengthen domestic mineral production, with antimony designated as a critical mineral for national security and technology applications. Currently, about 90% of global antimony supply comes from China, Russia, and Tajikistan.

NevGold CEO, Brandon Bonifacio, comments: “These recent results have some of the highest oxide gold-antimony grades that we have seen to date at Limo Butte. Resurrection Ridge is starting to build the drill-hole spacing and volume of holes to advance the Project to an initial gold-antimony Mineral Resource Estimate (“MRE”). Our main focus is to continue to release oxide gold-antimony results as we prepare for the upcoming 2025 drill program, with the objective of advancing the Project to the MRE within 2025. Our metallurgical testwork program also continues to advance positively and we expect to have results in the coming weeks. The environment is optimal to continue to advance and unlock the gold-antimony potential at Limo Butte as there is a clear commitment from the United States to advance high-quality, domestic, mineral projects.”

Limo Butte Geology & Antimony Summary
A review of historical geochemical and drilling data at the Limousine Butte Project has identified multiple areas with strong gold-antimony potential. These zones correlate closely with outcrops of the Devonian Pilot Shale, the primary host rock for Carlin-type gold mineralization in the area. Positive gold grade at Limousine Butte is typically associated with silicification and the formation of jasperoid breccias within the Pilot Shale, an alteration feature also observed in the positive antimony results.

Through the Project data review, the Company uncovered reports detailing two small-scale historic mining operations at the Nevada Antimony Mine and Lage Antimony Prospect within the Limo Butte Project boundary. The Nevada Antimony Mine featured two prospect pits that extracted stibnite (formula: Sb₂S₃) from a hydrothermal breccia. The Lage Antimony Prospect reported historical additional prospect pits extracting antimony.

Historical geochemical rock chip sampling within the past-producing Golden Butte pit from a Brigham Young University (“BYU”) Thesis study produced numerous results that exceeded 1% antimony in jasperoid breccias (see Figure 1). Several results were greater than 5% antimony, including a sample of 9.6% antimony with visible stibnite and stibiconite. BYU Thesis Report

US Executive Order – Announced March 20, 2025
The Company is pleased to report the recent, 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 no domestically mined 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 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”) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025))
