Lahontan Gold’s updated Santa Fe PEA shows an 11-year active mine life with post-tax NPV5 of US$820 million and IRR of 40.1%, using base-case prices of US$3,600/oz gold and US$49/oz silver. The study also projects average annual output of about 91,900 AuEq oz, pre-production capex of US$172 million, AISC of US$2,250/oz, and payback of 3.7 years; at spot-case prices of US$4,166/oz gold and US$59/oz silver, NPV5 rises to US$1.13 billion and IRR to 50.4%.

Management says the mine plan will feed into the final MPOO for BLM submission, with environmental baseline studies completed and federal/state permits targeted for 2027. The plan envisions open-pit mining and conventional heap leaching at Santa Fe, Calvada, Slab, and York, with average output increasing to roughly 112,500 AuEq oz in Years 4-11.
