en.Wedoany.com Reported - Recently, Hycroft Mining Holding Corporation (Nasdaq: HYMC) released a summary of its S-K 1300 technical report, initiating a preliminary economic assessment of its Hycroft gold-silver deposit located in Nevada, USA. The project proposes a combined process of conventional pressure oxidation beneficiation and heap leaching, with an initial capital expenditure estimated at $2.4 billion. It is expected to support a mine life of 51 years, with an average annual production of 204,000 ounces of gold and 6.8 million ounces of silver (equivalent to 295,000 ounces of gold).
Founded in 2017 and headquartered in Winnemucca, Nevada, Hycroft Mining Holding Corporation is a gold and silver company focused on the exploration and development of the Hycroft mine. Located in the Sulfur mining district, 54 miles west of Winnemucca, Nevada, the mine spans Humboldt and Pershing counties, covering approximately 64,000 acres, and is accessible year-round via Nevada State Route 49. Major shareholders include Canadian mining billionaire Eric Sprott and U.S. movie theater chain operator AMC Entertainment Holdings, Inc. The mine has over 30 years of operational history in oxide ore heap leaching, with mining operations suspended in November 2021 due to cost pressures. It is currently focused on technical research and development of sulfide ore resources. The mine has obtained permits for heap leaching and beneficiation operations, with existing on-site facilities including a three-stage crushing plant, heap leach pads, and two Merrill-Crowe plants (including a refinery).
The report evaluates two metal price scenarios: Under the base case scenario (gold at $3,600/oz, silver at $48/oz), the after-tax net present value is $4.3 billion, with an internal rate of return of 16.9% and a payback period of 4.7 years. Under the spot price scenario (gold at $4,569/oz, silver at $77.94/oz), the after-tax net present value is $10 billion, with an internal rate of return of 30.1% and a payback period of less than 3 years. The pressure oxidation beneficiation plant is designed to process 57,100 tons of ore per day, with all-in sustaining costs of $2,147 per gold equivalent ounce. Proven and probable resources amount to 16.4 million ounces of gold and 562.6 million ounces of silver; inferred resources (5 million ounces of gold and 132.8 million ounces of silver) were not included in this mine plan. The company also plans to advance the Brimstone and Vortex high-grade silver discoveries, combining underground and open-pit mining to access high-grade ore earlier, and is considering processing low-grade mill stockpiles.
