Los Azules Requests Admission to Argentina's Incentive Regime for Large Investments

TORONTO, February 11th, 2025 -- McEwen Copper Inc., a subsidiary of McEwen Mining Inc. (NYSE: MUX)

(TSX: MUX), is pleased to announce that its subsidiary Andes Corporación Minera S.A., has applied for

admission of the Los Azules copper project to Argentina's Large Investment Incentive Regime (“RIGI”).

The Los Azules Project involves an investment currently estimated at USD 2.7 billion, of which USD 227 million

have been committed under the RIGI to complete the feasibility study, conduct additional exploration and

perform preliminary work to render the project ready to commence construction. An additional investment of

USD 2.5 billion is estimated to build the mine and production facilities as a future expansion of the RIGI project.

Once admission to the RIGI is approved by the authority, Los Azules will have access to various benefits,

including a drop in the corporate income tax rate from 35% to 25%, relief from value added tax payment during

construction, exemption from export duties, and exclusion from the obligation to bring export proceeds into the

country, as well as 30-year stability and access to international arbitration in case of disputes.

Robert McEwen, Chairman and Chief Owner of McEwen Mining, stated: "Argentina is once again open for

business. The introduction of the RIGI provides both stability and incentives for large-scale

infrastructure investments. This is evident from the recent significant transactions in Argentina's mining

sector, all aimed at improving the standard of living for Argentinians and offering reasonable returns for

investors."

Michael Meding, Vice-President and General Manager of McEwen Copper, and General Manager of the Los

Azules Project, added: "Los Azules, one of the top 10 copper projects by resource size, has made

substantial progress in recent years. The recent approval of the environmental permit for construction

and operation marks an important milestone. The RIGI represents a key advancement for Argentina,

enhancing access to capital for vital infrastructure projects, including Los Azules."

McEwen Copper wishes to extend its most sincere gratitude to all those whose collaboration has been

instrumental in reaching this stage. We look forward to continued partnership and shared success as we

progress to the next phases of the project.

Next Steps: Towards Feasibility and Construction

With the approval of the EIA, the upcoming feasibility study scheduled for the first half of 2025, and the approval

of the application for admission to the RIGI, Los Azules has the potential to begin construction in early 2026,

which will strengthen even further McEwen Copper's position at the forefront of sustainable mining and as a

major driver of economic and social development in San Juan.

ABOUT MCEWEN COPPER

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

Elder Creek copper/gold project in Nevada, USA.

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

significantly less water, emitting much lower carbon, progressing towards carbon neutral by 2038, and being

estimates a $2.7 billion after-tax NPV8% at $3.75/lb Cu, a 27-year mine life, a copper resource of 10.9

billion pounds at grade 0.40% Cu (Indicated category) and an additional 26.7 billion pounds at grade 0.31% Cu

(Inferred category). For more details about the Los Azules PEA click here.
