NEVGOLD ADDS MORE SIGNIFICANT OXIDE GOLD-ANTIMONY RESULTS:

7.04 G/T AUEQ OVER 15.2 METERS (6.37 G/T AU AND 0.15% ANTIMONY)

WITHIN 4.14 G/T AUEQ OVER 29.0 METERS (3.56 G/T AU AND 0.13%

ANTIMONY), AND EXPANDS GOLD-ANTIMONY MINERALIZATION OVER 400

METERS ALONG STRIKE AT THE LIMOUSINE BUTTE PROJECT, NEVADA

Vancouver, British Columbia – June 4, 2025 – NevGold Corp. (“NevGold” or the “Company”)

(TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that it has discovered further

significant oxide gold-antimony (“Antimony”, “Sb”) drill results at its Limousine Butte Project (the

“Project”, “Limo Butte” ) in Nevada. The Company continues to unlock the substantial gold -antimony

potential of the Project, highlighting its promising prospects for further exploration and development in

Nevada, one of the world’s prolific mining jurisdictions.

Key Highlights

• Some of the highest gold-antimony grades seen to date at Resurrection Ridge including:

o LIM-46: 7.04 g/t AuEq* over 15.2 meters (6.37 g/t Au and 0.15% Sb ), within 4.14 g/t

AuEq* over 29.0 meters (3.56 g/t Au and 0.13% Sb)

o LB016: 0.61 g/t AuEq* over 36.6 meters from surface (0.16 g/t Au and 0.10% Sb)

extending mineralization over 400 meters along strike and opening up large, undrilled

areas of the Project for further expansion; the mineralization footprint now expands over

800 meters at Resurrection Ridge (see Figure 1, Figure 2) within a larger +5 km strike

length between Resurrection Ridge and Cadillac Valley (Figure 3)

o *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.

• Drillholes at Resurrection Ridge are drilled with spacing showing strong potential to advance

the Project to an initial gold-antimony Mineral Resource Estimate (“MRE”) (see Figure 1)

o Over 20 holes have been released to date ; the Company has more than 30 holes with

pending results from Resurrection Ridge and Cadillac Valley

• Metallurgical testwork program has commenced with over 100 kg bulk sample from the Project

and NevGold core drilling; results are expected over the coming weeks

• Resurrection Ridge and Cadillac Valley oxide gold-antimony mineralization demonstrates the

significant oxide gold-antimony potential across a large, open mineralized footprint (Figure

1, Figure 4)

o All areas at the Project with gold-antimony potential are permitted and ready to drill

under the Limo Butte Plan of Operations (“PoO”) approved in November -2024 (see

NevGold News Release from November 27, 2024)

• Significant antimony (Sb) upside: historical drilling had an upper detection limit of 1% Sb but

drill intervals exceeded the limit; these samples are currently being re-assayed at American Assay

Lab in Reno, Nevada

• NevGold will continue re -evaluating historical drilling from the Project, focusing on both oxide

gold and antimony

Limo Butte Planned 2025 Activities / Status Update

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

• Evaluate the historical geological database with focus on gold and antimony (in progress);

• Re-analyze historical drilling with focus on gold and antimony (in progress);

• Metallurgical testwork (in progress);

• Drill test gold-antimony targets (in planning phase).

NevGold CEO, Brandon Bonifacio , comments: “These results have some of the highest oxide gold-

antimony grades that we have seen to date at Limo Butte. We have also started to expand the mineralization

footprint at Resurrection Ridge, with over 800 meters defined, and we still have over 30 holes to releas e

prior to commencing our 2025 drill program. We are continuing to see exceptional oxide gold-antimony

results across a large area at the Project, and we will remain focused on adding to the mineralization

footprint and filling in some of the gaps in the gold-antimony geological database, with the goal of rapidly

advancing Limo Butte to an initial gold-antimony Mineral Resource Estimate (“MRE”) in 2025. Our

metallurgical testwork program continues to advance to outline the optimal flowsheet to recover the gold

and antimony, and we are expecting results over 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 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 f rom 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

NevGold VP Exploration, Greg French , comments: “These results are some of the strongest gold-

antimony grades seen at the Project. It is also encouraging to see the mineralization extend along strike to

the south where there is little antimony assay drill data, and to the north where there is minimal historical

drilling. With our robust understanding of the structures and key mineralization host rocks, these areas will

be a focus of our 2025 drilling as we look to expand the oxide gold -antimony mineralization footprint

along strike . We are excited to commence our 2025 drill program shortly which will be focused on

strengthening our current gold-antimony geological database , along with making new gold -antimony

discoveries.”

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 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 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))
