Project information
As at 31 December 2025
Description
As at 31 December 2025
Idaho Strategic's only production-stage property and the largest historic lode gold producer in northern Idaho, located ~1.5 miles east of Murray in the Murray Gold Belt of the Coeur d'Alene Mining District. The 100%-owned mine (Golden Chest, LLC) comprises an active underground operation, a no-longer-producing open pit and an exploration property, covering 34 patented claims (449 acres) and 217 unpatented claims (4,300 acres). Gold occurs as orogenic gold-quartz veins along the Idaho Fault in six ore shoots; current underground mining is focused on the H-Vein, with reserves also in the Jumbo, Paymaster and Idaho veins. In 2025 the company completed 19,362 metres of core drilling that converted resources to reserves. Ore is trucked off-site to the majority-owned New Jersey Mill. Production from Golden Chest and an adjacent Area of Interest is subject to a 2% net smelter return royalty payable to Equinox Gold. Mineral Reserves use a 4.0 g/t cutoff and a 3-year trailing average gold price of US$2,040/oz.

Lemhi Pass
Asset · Exploration
Project information
Description
A REE and thorium exploration-stage property ~25 miles southeast of Salmon, Idaho, straddling the Idaho-Montana border in the southern Idaho REE-Th Belt, comprising 678 unpatented lode claims plus a State of Idaho mineral lease over ~13,560 acres. USGS recognizes Lemhi Pass as the #1 thorium prospect in the United States; REE/thorium mineralization occurs in monazite associated with phosphorus. Historic USGS sampling of 31 vein samples showed TREO of 0.073%-2.20%; IDR sampling returned up to 6% total rare earths, and a 2025 carbonatite discovery at the Lucky Horseshoe prospect assayed up to 6.14% total rare earth oxides (65% magnet REO). In Q4 2025 IDR completed an inaugural 2,056-metre phase 1 drill program. The company signed an MOU with Clean Core Thorium Energy to evaluate a domestic thorium-based nuclear fuel supply chain. No mineral reserves or resources have been established; 67 leased claims carry a 2% NSR.

Description
As at 31 December 2025
A fully permitted 360-tonne-per-day flotation mill located two miles east of Kellogg, Idaho in the Coeur d'Alene Mining District, adjacent to Interstate 90, on the same property as the New Jersey Mine. Idaho Strategic is the manager and majority owner; the mill processes gold (and silver) ore from the 100%-owned Golden Chest Mine. A concentrate leach plant was decommissioned in 2024. In 2025 the mill processed 41,840 tonnes at an average head grade of 10.14 g/t gold with 93.0% gold recovery; since restarting in October 2016 it has milled a total of 372,348 tonnes. Three-phase power is supplied by Avista Utilities. The tailings storage facility is permitted with the Idaho Department of Water Resources.

How to read this tab
- The tables below list unit codes most often used in the Precious Metals sector for this company. MetalPilot stores contained metal or product in the codes below; grade and tonnage use separate fields. In side-by-side comparison views (stock page Portfolio tab, watchlist By sector), heterogeneous source units are converted to each commodity's preferred display unit (for example Moz Au, kt Cu, MMbbl oil) before summing; the same canonical codes appear in project data.
What the Portfolio tab shows
- The Portfolio tab presents a project-level view of the company's reported assets, built from publicly disclosed information (technical reports, annual filings, MD&A, investor presentations, MRMR / R&R statements, NI 43-101 / NI 51-101 / SEC S-K 1300 / SEC S-K 1200 / JORC / SAMREC / PERC / PRMS / COGEH filings, and similar primary sources).
- Figures are grouped by project type (mining, oil & gas, royalty, stream, processing facility, development, portfolio aggregate) and are shown alongside the headline reserve base, headline production, headline grade / quality, cost benchmarks, estimated lifetime, commercial terms (for royalties / streams), operational capacity (for processing) and a single-figure rating where the underlying data supports one.
- Each data table on the Portfolio tab is followed by ONE Assumptions footnote describing the modelling choices for that table; KPI stat-card assumptions appear in the bottom block instead. All legal and section disclaimers are merged into a single disclaimer list at the bottom of the Portfolio tab.
Concepts in your sector — Precious metals
- Resources vs Reserves. Resources are geological estimates that could one day be mined; Reserves are the subset with a feasibility study and plausible positive economics. Measured → Indicated → Inferred describe increasing geological uncertainty; Proven → Probable are reserve labels from Measured/Indicated. Inferred resources are not convertible to reserves under most codes.
- Grade (g/t) is the headline number on gold/silver pages. High-grade is often above 5 g/t; >10 g/t is bonanza territory; below 1 g/t is bulk low-grade. Open-pit cut-offs are typically lower than underground.
- AISC (All-In Sustaining Cost) is direct cash costs + sustaining capex + royalties + corporate overhead + reclamation, per ounce produced. C1 strips sustaining capex and corporate overhead. Both are non-GAAP and defined differently across issuers.
- By-product credits. Polymetallic deposits credit by-product value against the main metal cost; negative AISC after credits does not mean the main metal is sold below cash cost.
Portfolio tab — table guide
- Portfolio KPIs — company-level headline numbers aggregated from the featured projects (project counts, attributable annual production by commodity, attributable resource base by commodity, last filing date, operator share). USD value lines multiply attributable volumes by the resolved snapshot price.
- Portfolio snapshot — one-screen summary of the portfolio: counts by type and status, country mix, reporting standards used, operator share, primary commodity, attributable annual production summary and attributable resource base summary.
- Mining — one row per mining project, with columns for project name, location, status, primary commodities, production (with rating), reserves & resources (with rating), grade (with rating), costs and estimated lifetime. Multi-commodity projects emit one summary row per commodity.
- Royalty — one row per royalty interest held by the company. Columns cover the underlying project, operator, commodity, commercial terms (rate, type, cap, area-of-interest), attributable production, attributable reserves and estimated lifetime.
- Stream — one row per metal stream held by the company. Each row shows the underlying project, the streamed commodity, the headline stream percentage, the ongoing per-ounce / per-tonne payment, and attributable production / reserves.
- Processing facilities — one row per midstream / processing facility (pipeline, fractionator, LNG train, storage cavern, refinery, smelter, mill, heap-leach pad, CPP, etc.). Columns include nameplate capacity, contracted capacity, feedstock commodities and operational footprint.
- Development — projects in development status or in a pre-production lifecycle phase. The production column is re-labelled 'Targeted production (rating)' to highlight that the figures are plans, not actuals.
- Portfolio Aggregate — a single company-level row used when the company itself publishes a portfolio rollup (e.g. company-wide 2P barrels across all properties).
- Reserves & resources — detail — a leaf-category pivot showing every reserve and resource category disclosed across the projects.
- NPV (grouped) — all NPV rows captured from the filings, grouped by commodity, resource category, development status and pricing case. Each NPV figure is shown with its discount rate, basis (before-tax / after-tax), currency and value scale.
Ownership / Working interest
- Ownership percentage means the company's working-interest share of the asset: its slice of the project before royalties and before government take. It is shown on a 0–100 scale.
- Mines, oil and gas fields, and processing facilities — this is how much of the asset belongs to the company under that working-interest idea. One hundred percent is fully owned; a lower number usually means partners share the rest.
- Royalties and streaming agreements — the percentage is often not the story; what matters economically is usually the royalty or stream rate, shown elsewhere alongside these figures.
- Oil and gas — read this as gross working interest only. Do not treat it as net production or net wells after royalties; when filings distinguish gross from net, that shows up in how the resource numbers themselves are labelled.
- Below 100% — the short summary for each project names other owners and their stakes when the source says who they are.
- NRI vs WI (O&G). Working interest (WI) is the obligation to pay a share of costs; net revenue interest (NRI) is the share of revenue after royalties and overriding-royalty interests. A 100% WI well rarely produces 100% NRI; typical onshore U.S. NRI is 75–87.5% of WI depending on the lease royalty.
- Operator vs non-operator. The operator runs day-to-day operations; non-operating partners pay their WI share of costs but do not run the asset. Some Portfolio rows show operator share where disclosed.
Unit codes, conversion cheat sheets, cost benchmarks (AISC, C1–C3), reporting standards (NI 43-101, JORC, SEC S-K 1300) and resource/reserve category definitions live in the full terminology & units reference.
Each table lists the numeric band for scores 1–5 (production and resource base; grade where applicable for mining commodities) using the same thresholds as project rating stat cards. Only commodities that appear on featured projects for this document are listed.
Gold
Copper uses kt Cu bands (Mlb Cu when lb-scale copper resources appear on featured projects). Lithium grade uses hard-rock % Li₂O bands unless brine-style extraction or brine units appear on featured projects.
