Resolution expands Horse Heaven gold discovery

Resolution Minerals reported encouraging assay results from six diamond holes (c.1,600m) at the Golden Gate target within the Horse Heaven project, confirming continuous gold mineralisation across a 600m tested strike within an approximate 3km structure (only ~20% tested) and identifying a 200m width and 300m vertical extent of mineralisation. The company holds 100% of the 15,000-acre project adjacent to Perpetua Resources’ Stibnite development, is permitted and funded to drill an additional 45 holes in 2026, and is advancing the Antimony Ridge target with surface grades up to 50% Sb and discussions with the U.S. Department of Defense on strategic funding. These results, plus existing access and power upgrades crossing its tenements and secured financing, materially de-risk near-term exploration upside and the potential for both gold and strategic antimony supply contributions.

Analysis

Market structure: Resolution’s Horse Heaven results amplify value capture for immediate neighbours and mid-tier developers with permitted infrastructure—Perpetua (PPTA) stands to gain the most from positive sentiment and potential supply optionality for antimony and near‑surface gold. The discovery is unlikely to move global gold prices (current US$2,200) but strengthens US domestic critical‑metal supply narratives, increasing strategic premium for antimony producers and permitting‑ready projects over generic explorers. Expect capital to tilt toward brownfield/adjacent plays and service providers (drillers, geophysics) in the next 6–18 months, compressing financing spreads for well‑positioned juniors by 200–400bp versus high‑beta explorers.

Risk assessment: Key tail risks are permit reversals/community litigation tied to Stibnite permitting, negative metallurgical outcomes for antimony trisulfide, and capital dilution from follow‑on raises; any of these could erase >50% of junior market caps within weeks. Immediate (days) risk: headline disappointment on pending assays (4 holes due in 6–8 weeks); short term (months): DoD funding decision (0–6 months) and 2026 drill execution; long term (12–36 months): resource definition and metallurgy. Hidden dependency: Resolution’s economics implicitly rely on Perpetua infrastructure upgrades—if coordination or access terms change, capex and timeline risk rise materially.

Key Decisions for Investors

• Establish a 3% long position in PPTA (Perpetua) over the next 2–6 weeks to capture re‑rating from Stibnite progress and potential DoD funding announcements; layer in 1/3 now, 1/3 on any pullback >10%, 1/3 after positive DoD news.
• Establish a high‑risk tactical 1–2% long position in Resolution (ASX:RML or OTC:RLMLF) after next assay release (~6–8 weeks); if subsequent 2026 drilling plan confirms continuous strike beyond 1km of high‑grade intervals, scale to 3% max. Exit/trim to zero if assays show <0.5 g/t average across reported intervals or if metallurgy fails.
• Buy a 9–12 month call spread on PPTA: buy 25% OTM, sell 50% OTM (size equal to 2–3% portfolio long exposure) to limit premium outlay while retaining upside to permitting/DoD catalysts.
• Short 0.5–1% notional in GDXJ (or buy equivalent puts) as a hedge against a broad junior miner derating if market rotates away from high‑beta explorers; rebalance within 3 months or after a 15% move in PPTA/RML.
• Require three confirmatory events before materially increasing junior exposure: (1) next 4 hole assay batch (6–8 weeks), (2) positive metallurgical Sb2S3 lab report (0–3 months), (3) DoD funding/letter of interest (0–6 months); if any fail, reduce junior exposure by 50% within 7 days.
