VANCOUVER, BC, Jan. 16, 2024 /PRNewswire/ - Taseko Mines Limited (TSX: TKO) (NYSE American: TGB) (LSE: TKO) ("Taseko" or the "Company") is pleased to provide an update on financing and construction progress at its Florence Copper project.

On January 15, 2024, the Company signed a definitive agreement with Taurus Mining Royalty Fund L.P. ("Taurus") for the previously announced sale of a US$50 million royalty. The royalty will be for 1.95% of the gross revenue from the sale of all copper from Florence Copper. Funding of the US$50 million is subject to customary closing conditions, and proceeds are expected to be received in early February. The Company also expects to drawdown the first US$10 million of the US$50 million Mitsui financing later this month. With these financings in hand, construction activities at Florence will be accelerating.

To date, site activities have focussed on site preparations, earthworks and civil work for the commercial wellfield. The initial drilling contracts are now being finalized, with drilling of the commercial facility wellfield to commence in February. Additionally, the Company expects to sign a fixed-price contract with TIC Kiewit as general contractor for construction of the SX/EW plant and associated surface infrastructure. All the major plant components are onsite and the build will begin in the second quarter of this year.

Stuart McDonald, President & CEO of Taseko, commented, "Signing of the Taurus royalty agreement is another positive milestone for the project. We are excited to be ramping up construction activities at Florence Copper, which will soon be a major new supplier of low-carbon copper cathode to the US market.

Site preparations and civil work are well advanced, and we're looking forward to commencing wellfield drilling, with four rigs planned to be onsite initially. Construction of the SX/EW plant and other infrastructure represents a significant portion of the remaining project spend, and a fixed-price contract with TIC Kiewit will reduce inflationary risks, as Arizona continues to be a very active construction market. Our early work on detailed engineering and procurement of long-lead items has significantly de-risked the construction schedule and we're tracking towards first copper production in the fourth quarter of 2025. We're taking a disciplined approach to the buildout of the commercial facility at Florence, while our existing operations at the Gibraltar Mine continue to generate good cashflows in a strong copper price environment."

"As an existing copper producer, Taseko is in an enviable and unique position with near-term, low cost production growth coming from a fully-permitted and environmentally beneficial copper project. With copper now added to the US Department of Energy's critical materials list, market interest in our project and future copper production remains strong," added Mr. McDonald.

• uncertainties resulting from the war in Ukraine, and the accompanying international response including economic sanctions levied against Russia, which has disrupted the global economy, created increased volatility in commodity markets (including oil and gas prices), and disrupted international trade and financial markets, all of which have an ongoing and uncertain effect on global economics, supply chains, availability of materials and equipment and execution timelines for project development;
• uncertainties about the continuing impact of the novel coronavirus ("COVID-19") and the response of local, provincial, state, federal and international governments to the ongoing threat of COVID-19, on our operations (including our suppliers, customers, supply chains, employees and contractors) and economic conditions generally including rising inflation levels and in particular with respect to the demand for copper and other metals we produce;
• inherent risks associated with mining operations, including our current mining operations at Gibraltar, and their potential impact on our ability to achieve our production estimates;
• uncertainties as to our ability to control our operating costs, including inflationary cost pressures at Gibraltar without impacting our planned copper production;
• the risk of inadequate insurance or inability to obtain insurance to cover material mining or operational risks;
• uncertainties related to the feasibility study for Florence copper project (the "Florence Copper Project" or "Florence Copper") that provides estimates of expected or anticipated capital and operating costs, expenditures and economic returns from this mining project, including the impact of inflation on the estimated costs related to the construction of the Florence Copper Project and our other development projects;
• the risk that the results from our operations of the Florence Copper production test facility ("PTF") and ongoing engineering work including updated capital and operating costs will negatively impact our estimates for current projected economics for commercial operations at Florence Copper;
• uncertainties related to the accuracy of our estimates of Mineral Reserves (as defined below), Mineral Resources (as defined below), production rates and timing of production, future production and future cash and total costs of production and milling;
• the risk that we may not be able to expand or replace reserves as our existing mineral reserves are mined;
• the availability of, and uncertainties relating to the development of, additional financing and infrastructure necessary for the advancement of our development projects, including with respect to our ability to obtain any remaining construction financing potentially needed to move forward with commercial operations at Florence Copper;

• uncertainties related to our ability to obtain necessary title, licenses and permits for our development projects and project delays due to third party opposition;
• our ability to deploy strategic capital and award key contracts to assist with protecting the Florence Copper project execution plan, mitigating inflation risk and the potential impact of supply chain disruptions on our construction schedule and ensuring a smooth transition into construction;
• uncertainties related to First Nations claims and consultation issues;
• our reliance on rail transportation and port terminals for shipping our copper concentrate production from Gibraltar;
• uncertainties related to unexpected judicial or regulatory proceedings;
• changes in, and the effects of, the laws, regulations and government policies affecting our exploration and development activities and mining operations and mine closure and bonding requirements;
