The updated Preliminary Economic Assessment (PEA) for Lahontan Gold Corp. (TSX.V: LG) (OTCQB: LGCXF)’s flagship Santa Fe Mine in Nevada’s Walker Lane projects estimated net cash flow of US$1.68 billion before taxes and US$1.32 billion after taxes over an 11-year active mine life. The study, released on October 14, 2026, also outlines a post-tax net present value at a 5% discount rate of US$820 million and an internal rate of return of 40.1% at base-case prices of US$3,600 gold and US$49 silver. These figures matter because they provide a credible production plan and defined capital requirements, which are essential for attracting financing and moving a project toward construction in a sector where new mines take years to permit and build.
The PEA details that output steps up to roughly 112,500 Au Eq ounces a year from Year 4 through Year 11, with four years of the plan topping 120,000 ounces. That production profile, combined with the strong cash flow estimates, positions Santa Fe as a potential significant contributor to Nevada’s gold output. According to the U.S. Geological Survey, Nevada accounted for about 64% of U.S. gold mine production in 2025, so a new mine of this scale could reinforce the state’s dominance in domestic gold mining.
Gold is holding over US$4,100 an ounce though mid-October, a level few mine plans were built around, but higher prices don’t produce new ounces on their own. The projects best placed to benefit are those with credible production plans, defined capital requirements and economics that can withstand a retreat in metal prices. Lahontan’s PEA, with its base-case price of US$3,600 gold, demonstrates that the project’s economics remain robust even at lower prices. That upside sensitivity is a key reason the study is important: it shows the project can generate strong returns in a range of price environments.
For investors, the updated Preliminary Economic Assessment offers a clearer picture of Santa Fe’s potential, including the NPV and IRR that are critical for valuation.
