NevGold CEO, Brandon Bonifacio, comments: “We continue to see exceptional oxide gold-antimony results from our Limo Butte Project in Nevada. The discovery of more significant oxide gold-antimony drill results at Resurrection Ridge continues to be a key development with the focus of advancing the Project to an initial Mineral Resource Estimate (“MRE”) in 2025. We have also recently commenced a robust metallurgical testwork program to define the optimal flowsheet to recover the gold and antimony, which is a key step for further project advancement. We still have a number of drillholes to release with combined gold-antimony results which will further build on the mineralization footprints that we have defined to date at Resurrection Ridge and Cadillac Valley. The timing and market conditions provide an optimal environment to advance the gold-antimony potential at Limo Butte as there is a clear commitment from the United States to advance high-quality, domestic, mineral projects.”

Historical and Re-Assayed Drill Results

*Downhole thickness reported; true width varies depending on drill hole dip and is approximately 70% to 90% of downhole thickness.
**The gold equivalents (“AuEq”) are based on assumed metals prices of US$2,000/oz of gold and US$35,000 per tonne of antimony (~30% discount to current spot prices), and assumed metals recoveries of 85% for gold and 70% for antimony.
***Selected drillholes released in previous News Releases on February 27, 2025, March 26, 2025, April 10, 2025, and April 24, 2025.
**** Historical drilling had an upper detection limit of 1% Sb but many drill intervals exceeded the limit.

Limo Butte Geology & Antimony Potential

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 unverified sampling results with up to 14.46% Antimony with additional prospect pits extracting antimony.

Historical geochemical rock chip sampling within the past-producing Golden Butte pit from a Brigham Young University 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

NevGold VP Exploration, Greg French, comments: “We are pleased with the level of consistency in thickness and oxide gold-antimony grades that we are seeing in the historic data and the re-assay program. It is clear that we have two large mineralization footprints at Resurrection Ridge and Cadillac Valley with over 5 km of strike length defined between the target areas. There are also a number of other advanced target areas with gold-antimony potential within the project boundary that we will look to explore in 2025. To further advance the development of the project, we have also commenced a robust metallurgical program which will help define the optimal flowsheet to recover both gold and antimony.”

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 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.

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. (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))
