Lahontan Drills 16.5m Grading 2.72 g/t Au and 2.8 g/t Ag at Santa Fe Heap Leach Pad Two

Lahontan Gold’s first 10 of 26 Sonic drill holes at the Santa Fe Mine’s Heap Leach Pad Two returned a weighted average of 0.50 g/t gold and 3.3 g/t silver, or 0.54 g/t Au equivalent, above the estimated residual grade of 0.32 g/t Au equivalent. Cyanide-leach gold recovery assays averaged 40% of fire-assay values, indicating potential for conventional cyanide reprocessing of historic heap-leach material. The company plans to report results from 86 additional Sonic holes across four historic pads as it evaluates a potential resource and targets a Santa Fe production restart in 2027.

Analysis

The economic signal is not the reported residual grade but the potential conversion of a historically processed liability into low-strip, low-discovery-cost feed. If subsequent drilling establishes tonnage and recoveries at scale, reprocessing could improve Santa Fe’s early-year cash-flow profile and reduce dependence on higher-capex sulfide development. The key valuation lever is whether this material can be incorporated into a mine plan without requiring meaningful new crushing, agglomeration, pad capacity, or water infrastructure; absent that proof, the market should assign little value to the drill result.

Near-term upside in LG is likely retail/liquidity-driven as the remaining pad assays arrive over the next 1-3 months, but the company’s proposed production timeline requires financing and permitting credibility rather than additional grade headlines. Heap material is unusually heterogeneous, so an average from the initial subset has weak predictive value for recoverable ounces and could decline materially as sampling expands. The company’s cyanide test is also an indicative short-duration laboratory result, not a bankable recovery estimate: column-leach kinetics, reagent consumption, permeability, and solution management determine actual economics.

Contrarian view: the release could be over-interpreted as new resource growth when it may instead identify processing inventory with modest margin after rehandling, leach-cycle time, and sustaining-capital costs. Conversely, if pad feed can be sequenced ahead of fresh mining, its principal value is financing de-risking: earlier cash generation can lower dilution and improve the probability of project construction. This is a micro-cap single-asset optionality trade, not a clean read-through to Nevada peers such as AEM, NEM, or KGC.

Key Decisions for Investors

• Maintain LG as a watchlist/speculative position only; do not add solely on assay headlines. Reassess after the full pad-drilling dataset and an independently supported tonnage-recovery-cost estimate, expected within 1-3 months.
• For an existing LG position, take partial profits into liquidity-driven strength and retain a small catalyst stub through the updated PEA. Require the PEA to quantify pad-related recovered ounces, processing cost per tonne, incremental capital, and schedule impact before increasing exposure.
• Set a thesis-failure trigger if expanded sampling materially lowers average recoverable grade or if cyanide column tests demonstrate poor kinetics/recovery versus laboratory indications; either outcome would eliminate the low-capital-feed thesis.
• Do not use large-cap gold miners as a direct pair short. If gold-price exposure is desired while awaiting project-specific data, hedge a small LG position with GDX rather than assuming Santa Fe technical risk will correlate with bullion.
