Lahontan Gold unveils $820m Santa Fe valuation as Nevada mine restart moves closer

Lahontan Gold Corp. has unveiled dramatically stronger economics for its Santa Fe gold-silver project in Nevada, estimating a post-tax net present value of approximately $820 million and a 40.1% internal rate of return under its updated preliminary economic assessment. The development-stage miner projects approximately $1.32 billion of after-tax net cash flow and $3.68 billion of total revenue across an 11-year active mine life, followed by one year of residual heap leaching. Initial capital requirements are estimated at $172 million, while average annual production is projected at approximately 91,900 gold-equivalent ounces and rises considerably during the stronger middle years of the mine plan. Despite those headline economics, Lahontan Gold shares fell roughly 11% on the TSX Venture Exchange during Wednesday trading, showing that investors remain focused on the assumptions behind the study, financing requirements and the considerable work still required before Santa Fe becomes an operating mine.

The updated assessment represents a major improvement from Lahontan Gold’s previous 2024 study, when Santa Fe carried a post-tax net present value of approximately $56.5 million. Management highlighted the more than fourteen-fold increase as evidence of how resource expansion, revised mine planning and stronger precious-metals prices have transformed the project’s potential economics. Investors should nevertheless recognize that the comparison is not like-for-like: the new base case assumes gold at $3,600 per ounce and silver at $49 per ounce, substantially stronger commodity prices than were incorporated into the earlier development case. The new study is also preliminary and includes inferred mineral resources that are not yet classified as mineral reserves, meaning its projected economics are not guaranteed to be realized.

Why Lahontan Gold’s $820 million Santa Fe valuation represents a major project upgrade

The scale of the new economics changes the investment discussion around Santa Fe because Lahontan Gold is no longer evaluating a relatively modest restart built only around shallow oxide material. The updated study incorporates a much larger resource base and expands the development concept to include sulfide mineralization beneath the historically mined oxide deposits. Santa Fe now contains an indicated mineral resource of approximately 1.195 million gold-equivalent ounces and an inferred resource of another 1.190 million ounces, giving the project about 2.385 million gold-equivalent ounces across its current resource categories. The August resource update represented a 22% increase, or approximately 435,000 additional gold-equivalent ounces, from the previous estimate.

The preliminary economic assessment estimates that approximately 1.03 million gold-equivalent ounces could be produced during the modeled mine life. That includes about 986,600 ounces of gold and approximately 2.85 million ounces of silver, with average annual output of roughly 91,900 gold-equivalent ounces. Production is heavily weighted toward later years: output is projected at only 22,900 gold-equivalent ounces in the first year before increasing above 120,000 ounces during several years once higher-grade material enters the processing schedule.

That production profile matters when evaluating both payback and financing. Lahontan Gold estimates a 3.7-year payback period under the base case, meaning the company would need to fund construction and absorb the lower-output initial years before the strongest cash generation arrives. Pre-production capital of approximately $172 million includes a $22.2 million contingency, while additional sustaining capital would be required during operations.

The projected operating economics are reasonably robust at the base-case metal prices but leave meaningful sensitivity to gold prices. Lahontan Gold estimates cash costs of approximately $1,909 per ounce and all-in sustaining costs of roughly $2,250 per ounce. At $3,600 gold, those costs provide substantial theoretical margin; at weaker commodity prices, the economics narrow quickly. The PEA’s lower-price scenario using $3,000 gold and $30 silver still produces an estimated $476.2 million post-tax net present value and 27.3% internal rate of return, suggesting the project remains economically positive under less favorable assumptions, although those results remain preliminary.

Gold prices are doing considerable work in Lahontan Gold’s new Santa Fe economics

The strongest headline numbers are built around a precious-metals environment that is considerably stronger than what mining companies historically used for long-term planning. Lahontan Gold’s base-case assumption of $3,600 per ounce of gold sits below the $4,166 spot-price reference used in the sensitivity analysis as of October 13, but it is still a high absolute price relative to historical development studies. Silver is modeled at $49 per ounce in the base case.

That does not make the study invalid, particularly when spot metal prices support higher assumptions, but it means commodity-price sensitivity deserves prominent attention. At the study’s spot-price case of $4,166 gold and $59 silver, Santa Fe’s post-tax net present value increases to approximately $1.13 billion and its internal rate of return rises to 50.4%. At $3,000 gold and $30 silver, the post-tax value drops to approximately $476 million. The roughly $656 million difference between those two net present value outcomes demonstrates just how strongly Santa Fe’s valuation responds to metal prices.

Investors should therefore avoid treating $820 million as a fixed asset value. A preliminary economic assessment is a model built from assumptions covering metals prices, recoveries, mining costs, processing costs, capital expenditure, permitting and future production schedules. Changes in any of those variables can materially alter the outcome before a mine reaches construction.

Santa Fe does have one advantage compared with a completely undeveloped property: it is a former producing mine. The site produced approximately 359,202 ounces of gold and 702,067 ounces of silver between 1988 and 1995 through open-pit mining and heap-leach processing. Four historic pits already exist across the project, and Lahontan Gold argues that the brownfield setting, existing technical knowledge and established infrastructure can reduce development complexity compared with constructing an entirely new mine in an undeveloped location.

A $172 million construction bill puts financing at the center of the Lahontan Gold investment case

Santa Fe’s projected economics may be large relative to Lahontan Gold’s current valuation, but turning theoretical project value into shareholder value requires financing construction. Lahontan Gold had a market capitalization of approximately C$168.6 million immediately before Wednesday’s trading session, while estimated pre-production capital for Santa Fe is US$172 million. Those figures use different currencies and measure different things, but the comparison illustrates that building Santa Fe would represent a very substantial financial commitment relative to the company’s present equity size.

Lahontan Gold has strengthened its near-term funding position. The company raised approximately C$13.6 million earlier this year through a private placement and subsequently said those proceeds, combined with continuing warrant exercises, leave it fully funded into 2027. That capital is intended to support exploration, technical studies and permitting rather than fully finance construction of the mine.

A future construction package could ultimately involve some combination of equity, debt, project finance, streaming or royalty capital, strategic investment, or partnerships. Each structure carries different consequences for shareholders. Heavy equity financing could significantly increase the number of shares outstanding, while debt financing would introduce interest and repayment requirements before Santa Fe achieves its strongest production years. Streaming or royalty agreements could reduce upfront financing pressure but surrender a portion of future commodity revenue.

The quality of the PEA could improve Lahontan Gold’s financing options because lenders and strategic investors generally prefer projects demonstrating strong expected returns and manageable capital intensity. A 40.1% modeled internal rate of return and 3.7-year payback period create a more compelling financing proposition than the economics outlined in the earlier study, but financing terms will ultimately depend on more advanced engineering, permitting progress, commodity markets and lender confidence.

Permitting and the 2027 construction target now become the next major Santa Fe catalysts

Lahontan Gold has been advancing state and federal permitting alongside drilling and engineering rather than waiting for the economic assessment to be completed. Environmental baseline studies are finished, and the company plans to use the new mine schedule as the foundation for its final Mine Plan of Operations submission to the United States Bureau of Land Management. Management continues to target receipt of the major federal and state approvals required for construction during 2027.

That timetable remains ambitious. Mine permitting can encounter regulatory review, requests for additional technical work, environmental considerations or public consultation that extend beyond management schedules. Lahontan Gold itself acknowledges the forward-looking nature of its construction timeline, so investors should treat 2027 as a target rather than a guaranteed start date.

The company has nevertheless completed substantial development work during 2026. By the end of June, Lahontan Gold had drilled 87 holes totaling approximately 7,751 metres during the year while simultaneously advancing groundwater modeling, geochemical characterization, heap-leach pad testing and exploration around existing resource areas.

Further exploration could also change the economics before construction. Mineralization remains open around portions of the known Santa Fe deposits and at depth, while drilling of historic heap-leach pads is evaluating whether residual gold and silver can be economically recovered. Lahontan Gold is also exploring its nearby West Santa Fe property, where management is targeting an initial mineral resource estimate, creating the possibility of a broader Nevada development platform rather than dependence on a single deposit.

Lahontan Gold strengthened that regional strategy in September through its proposed acquisition of Emergent Metals Corp. The transaction would give Lahontan full ownership of West Santa Fe, eliminate several royalties and add the adjacent New York Canyon project. Management estimated that consolidating West Santa Fe alone removes approximately C$2.39 million of future payments that would otherwise have been required to obtain the remaining project interest.

Lahontan Gold stock falls despite the much stronger Santa Fe economic study

Investor reaction to the PEA was notably negative. Lahontan Gold shares traded around C$0.345 on the TSX Venture Exchange during Wednesday afternoon activity, down roughly 11.5% from the previous close of C$0.39. The U.S. OTC-listed shares were also lower, trading around $0.25 after closing the prior session near $0.27. Trading volume increased materially on the Canadian listing as investors digested the project economics.

The decline may appear counterintuitive given that the headline net present value increased dramatically, but the market reaction highlights the difference between economic studies and operating cash flow. Santa Fe still has no mineral reserves, requires substantial construction financing and must obtain additional permits before production can restart. The preliminary study also relies on strong gold and silver assumptions, while its production schedule begins relatively slowly before higher-grade years improve economics.

Longer-term sentiment has nevertheless strengthened considerably. Lahontan Gold’s Canadian market capitalization had increased more than 100% in 2026 through October 13 and approximately 245% over the preceding year, reflecting growing investor expectations around resource expansion, higher gold prices and the possibility of restarting Santa Fe.

That prior appreciation may partly explain why even a substantially improved PEA failed to trigger another rally. Expectations had already risen significantly ahead of the announcement, and investors may now be shifting attention from resource expansion toward the harder questions of financing, permitting and actual construction.

The next stage of the Lahontan Gold story will therefore require more than additional ounces or higher modeled values. Management must convert Santa Fe from a development asset into a permitted and financeable mine while minimizing dilution and preserving enough of the project economics for existing shareholders. If the company achieves those objectives, the difference between Lahontan Gold’s current equity valuation and the project’s modeled net present value could remain compelling. If construction costs increase, commodity prices weaken or permitting is delayed, that apparent valuation gap could narrow substantially before production begins.
