About Nuton

Nuton is an innovative new venture that aims to help grow Rio Tinto’s copper business. At the

core of Nuton is a portfolio of proprietary copper leach-related technologies and capability – a

product of almost 30 years of research and development. Nuton ™ Technologies offer the

potential to economically unlock copper sulphide resources, copper bearing waste and tailings,

and achieve higher copper recoveries on oxide and transitional material, allowing for a

significantly increased copper production. One of the key differentiators of Nuton is the

potential to deliver leading environmental performance, including more efficient water usage,

lower carbon emissions, and the ability to reclaim mine sites by reprocessing mine waste.

About McEwen Copper

McEwen Copper Inc. holds a 100% interest in the Los Azules copper project in San Juan,

Argentina and the Elder Creek project in Nevada, USA.

Los Azules was ranked in the top 10 largest undeveloped copper deposits in the world by

Mining Intelligence (2022). Its curren t copper resources are estimated at 10.9 billion pounds

at a grade of 0.40% Cu (Indicated category) and an additional 26.7 billion pounds at a grade

of 0.31% Cu (Inferred category). A PEA published in June 2023 estimated a $2.7 billion after-

tax NPV8% at $3.75/lb Cu and a 27-year mine life.

After closing the Stellantis investment, also announced today, and the pending investment by

Nuton, McEwen Copper will have 30,937,615 common shares outstanding, and its

shareholders are: McEwen Mining Inc. 47.7%, Stella ntis 19.4%, Nuton 14.5%, Rob McEwen

12.9%, Victor Smorgon Group 3.2%, and other shareholders 2.3%.”

The McEwen Mining press release appears to be reviewed and verified by a Qualified Person (as that

term is defined by National Instrument 43 -101 – Standards of Disclosure for Mineral Projects ) and the

procedures, methodology and key assumptions disclosed therein are those adopted and consistently

applied in the mining industry, but no Qualified Person engaged by TNR has done sufficient work to

analyze, interp ret, classify or verify McEwen Mining’s information to determine the current mineral

resource or other information referred to in its press releases. Accordingly, the reader is cautioned in

placing any reliance on the disclosures therein.

“We are pleased that significant developments on the advancement of the Los Azules Copper Project

towards feasibility have led to the increased Stellantis holdings in McEwen Copper, as a strategic partner

in the future development of this giant copper, gold and silver project. In February 2023 Stellantis invested

ARS $30 billion, and with this additional investment of ARS $42 billion, has a total investment of ARS

$72 billion. An investment of US $10 million in McEwen Copper was also invested by Rio Tinto's Venture

Nuton after its initial US $25 million investments in 2022 and US $30 million in 2023,” stated Kirill Klip,

TNR’s Chief Executive Officer. “TNR Gold's vision is aligned with the leaders of innovation among

automakers like Stellantis, whose aim is decarbonizing mobility, and mining industry leaders like Rob

2

McEwen’s vision ‘to build a mine for the future, based on regenerative principles that can achieve net

zero carbon emissions by 2038’.

The green energy rEVolution relies on the supply of critical metals like copper; delivering "green copper"

to Argentina and the world will contribute to the clean energy transition and electrification of transportation

and energy industries.

Strong team performance is accelerating the McEwen Copper Los Azules program in 2023. The Los

Azules Project preliminary economic assessment (PEA) results highlighted the potential to create very

robust leach project, while reducing environmental footprint, and greater environmental and social

stewardship sets the Project apart from other potential mine developments.

It’s very encouraging to see an updated independent mineral resource estimate that has increased

significantly.

Together with Nuton, McEwen Copper is exploring new technologies that save energy, water, time and

capital, advancing Los Azules towards the goal of the leading environmental performance. The

involvement of Rio Tinto with its innovative technology, may also accelerate realizing the enormous

potential of the Los Azules Project.

Los Azules was ranked in the top 10 largest undeveloped copper deposits in the world by Mining

Intelligence (2022). TNR Gold does not have to contribute any capital for the development of the Los

Azules Project. The essence of our business model is to have industry leaders like McEwen Mining as

operators on the projects that will potentially generate royalty cashflows to contribute significant value for

our shareholders.”

ABOUT TNR GOLD CORP.

shareholder holding a 0.05% NSR royalty.

Project is to attract a joint venture partnership with a major gold mining company. The Company is
