NEWS RELEASE

MINAURUM GOLD INC.

FOR RELEASE: June 3, 2025 TRADING SYMBOL TSX.V: MGG

Minaurum Announces Exercise of Option to Acquire

Lone Mountain CRD Project in

Nevada’s Battle Mountain-Eureka Trend

Minaurum Gold Inc. (“Minaurum” or “ the Company”) (TSXV: MGG) (OTCQX:MMRGF) is

pleased to announce that, further to its news release dated October 2, 2024, it has provided the

required notice to Nevada Zinc Corp. (“Nevada Zinc”) to exercise its option (the “Option”) to

acquire a 100% registered and beneficial interest in the Lone Mountain carbonate replacement

deposit (“CRD”) project (the “Acquisition”) located on the Battle Mountain-Eureka Trend in

Nevada, USA (“Lone Mountain” or the “Project”). The Company is acquiring the Project

pursuant to an option agreement between the Company and Nevada Zinc dated July 24, 2024, as

amended on October 22, 2024 and December 24, 2024.

Nevada Zinc completed a Preliminary Economic Assessment of the viability of potentially mining

the zinc mineralization at the Project in June 2019 (NI 43-101 Preliminary Economic Assessment

and Technical Report, Peimen Ling & Associates Limited, June 27, 2019 or see Nevada Zinc news

release dated June 27, 2019 (the “PEA”).

In accordance with the disclosure in the PEA, the Project is a brownfields project with a historic

inferred mineral resource estimate of 3,257,000 tonnes grading 7.57% zinc and 0.70% lead.

Select drilling highlights include 118.87 m of 9.58% Zn and 0.74% Pb (hole LM-15- 27); and

24.7 m grading 23.06% Zn (hole NLM-17-08). The PEA also demonstrated a 35% after tax

internal rate of return ("IRR"). See below for further details on the Mineral Resource Estimate

Report and the PEA.

“Lone Mountain looks a lot like neighbouring historical silver -lead-zinc CRDs, such as

Eureka next door or Cortez up the road, both of which have been found to have a significant

Carlin Gold overprint,” said Dr. Peter Megaw, Co -founder and Exploration Advisor to

Minaurum. “Historical drilling was tightly focused on near -surface high-grade zinc oxides

and did not seek that kind of gold mineralization or the polymetallic CRD sulphide potential

that should lie beneath.”

“We are pleased to acquire Lone Mountain, an advanced project with robust economics that

we believe could host significant silver and gold mineralization at depth” stated Darrell Rader,

President & CEO of Minaurum. “As we advance our flagship Alamos silver project toward a

maiden resource in 2025, we’re strategically positioning Lone Mountain as the next catalyst

for value creation in Minaurum’s portfolio.”

Acquisition Terms

In consideration of the Acquisition, the Company will:

(i) issue Nevada Zinc a number of common shares of the Company (the “Payment Shares”) having

an aggregate value of $1,000,000 based on the 10-day volume weighted average trading price

of the common shares on the TSX Venture Exchange (“TSXV”) for the 10 trading days

immediately preceding the date of issuance; and

(ii) pay Nevada Zinc a cash fee in the amount of $100,000.

The completion of the Acquisition, including the issuance of the Payment Shares to Nevada Zinc,

is subject to customary closing conditions, including, without limitation, approval of the TSXV.

The Payment Shares will be subject to: (a) a four -month and one day statutory hold period, in

accordance with applicable securities laws; and (b) a contractual restriction on transfer pursuant to

which Nevada Zinc may not sell more than 500,000 Payment Sha res per week after the expiry of

the statutory hold period.
