Nevgold Mobilizes Drill to Test Historical Leach Pads to Advance the Near-Term Antimony Production Scenario at Limo Butte
NEVGOLD MOBILIZES DRILL TO TEST HISTORICAL LEACH PADS TO ADVANCE
THE NEAR-TERM ANTIMONY PRODUCTION SCENARIO AT LIMO BUTTE
Vancouver, British Columbia – March 1 2, 2026 – NevGold Corp. (“NevGold” or the “Company”)
(TSXV:NAU) (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 opportunitie s 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 jurisdiction s 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):
o 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
o Drilling will be completed over the coming weeks
o Certain areas of the leach pads had Phase I sampling results of 0.74% Sb to 0.81% Sb
(See Figure 1)
• Metallurgical testwork completed by NevGold highlights the strong geometallurgical
characteristics of the Project, with acid leaching the preferred recovery method for antimony:
o 2025 testwork using acid leaching resulted in antimony recoveries of up to 92%
o 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
o 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
o Historical leach pads provide opportunity for near-term antimony production
o 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
o 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 provisi ons 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 t o 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 ammu nition, 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. (see
Perpetua Resources News Release from October 27, 2025)
