In connection with the Transaction, McEwen Copper and certain of its affiliates entered into an

Amended Collaboration Agreement (the " New Nuton Collaboration Agreement”) and a

Copper Cathodes and Concentrates Purchase Rights Agreement (the “ CCCPRA”), which are

described below.

The New Nuton Collaboration Agreement provides for the following additional rights beyond

those in the original Nuton Collaboration Agreement (see news release dated Aug 31, 2022):

• Nuton will have the opportunity to provide local currency funding, in certain circumstances,

for advancement of the Los Azules project;

• Comprehensive scientific, technical and strategic planning information rights;

• Extension of exclusivity over novel, trade secret or patented copper heap leach

technologies until August 10, 2024;

• Pre-emptive rights to maintain their ownership percentage in any follow-on equity offering;

and

• Agreement of McEwen Mining and Rob McEwen to not trigger Drag Along Rights in the

event of a bid for McEwen Copper prior to the planned initial public offering (IPO).

The CCCPRA provides an option to Nuton that, if exercised to its maximum extent, would allow

them to purchase a percentage of the copper products (cathodes, concentrates, etc.) produced

from the Los Azules project equal to their equity ownership percentage in McEwen Copper at

the time of exercise.

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.

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.

TNR Gold Corp. is working to become the green energy metals royalty and gold company.

Our business model provides a unique entry point in the creation of supply chains for critical materials

like energy metals that are powering the energy rEVolution, and the gold industry that is providing a

hedge for this stage of the economic cycle.

Our portfolio provides a unique combination of assets with exposure to multiple aspects of the mining

cycle: the power of blue-sky discovery and important partnerships with industry leaders as operators on

the projects that have the potential to generate royalty cashflows that will contribute significant value for

our shareholders.

Over the past twenty-seven years, TNR, through its lead generator business model, has been successful

in generating high -quality global exploration projects. With the Co mpany’s expertise, resources and

industry network, the potential of the Mariana Lithium Project and Los Azules Copper Project in Argentina

among many others have been recognized.

TNR holds a 1.5% NSR Royalty on the Mariana Lithium Project in Argentina, of which 0.15% NSR royalty

is held on behalf of a shareholder. Ganfeng Lithium’s subsidiary, Litio Minera Argentina (“LMA”), has the

right to repurchase 1.0% of the NSR royalty on the Mariana Project, of which 0.9% is the Company’s

NSR Royalty interest. The C ompany would receive CAN$900,000 and its shareholder would receive

CAN$100,000 on the repurchase by LMA, resulting in TNR holding a 0.45% NSR royalty and its

shareholder holding a 0.05% NSR royalty.

The Mariana Lithium Project is 100% owned by Ganfeng Lithium. The Mariana Lithium Project has been

approved by the Argentina provincial government of Salta for an environmental impact report, and the

construction of a 20,000 tons-per-annum lithium chloride plant has commenced.

TNR Gold also holds a 0.4% NSR Royalty on the Los Azules Copper Project, of which 0.04% of the 0.4%

NSR royalty is held on behalf of a shareholder . The Los Azules Copper Project is being developed by

McEwen Mining.

TNR also holds a 7% net profits royalty holding on the Batidero I and II properties of the Josemaria Project

that is being developed by Lundin Mining. Lundin Mining is part of the Lundin Group, a portfolio of

companies producing a variety of commodities in several countries worldwide.

TNR provides significant exposure to gold through its 90% holding in the Shotgun Gold porphyry project

in Alaska. The project is located in Southwestern Alaska near the Donlin Gold project, which is being

developed by Barrick Gold and Novagold Resources. The Company’s strategy with the Shot gun Gold

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

actively introducing the project to interested parties.

At its core, TNR provides a wide scope of exposure to gold, copper, silver and lithium through its holdings

in Alaska (the Shotgun Gold porphyry project) and royalty holdings in Argentina (the Mariana Lithium

project, the Los Azules Copper Project and the Batidero I & II properties of the Josemaria Project), and

is committed to the continued gene ration of in -demand projects, while diversifying its markets and

building shareholder value.
