Project information
As at 18 December 2025
Description
As at 18 December 2025
Open-pit heap-leach gold-silver mine located in the Oatman Mining District, Mohave County, Arizona, USA, approximately 10 miles east of Bullhead City. Acquired by Mako on March 27, 2025 out of the bankruptcy of Elevation Gold Mining Corp. (former Northern Vertex). The processing flowsheet is conventional crush-and-stack heap leach with Merrill-Crowe gold-silver recovery (cement agglomeration not required given good crushed material permeability). Updated 2025 NI 43-101 Mineral Resource Estimate (effective December 18, 2025, filed March 10, 2026) supersedes prior NVMC/Elevation estimates. The Company is in the process of restarting full production while advancing the project toward a NI 43-101 Mineral Reserve Estimate. Royalty obligations include Greenwood, La Cuesta and (subject to litigation) Minquest and Patriot Gold.

Mt. Hamilton Project
Asset · Pre-feasibility
Project information
As at 23 September 2025
Description
As at 23 September 2025
100%-owned gold-silver project located in the White Pine Mining District, White Pine County, Nevada, along the southern portion of the Battle Mountain-Eureka Trend. The Property comprises the Seligman, Centennial and Seligman Stock (Igneous) deposits — gold-skarn deposits with possible Carlin-type overprint. Updated 2025 Mineral Resource Estimate (effective September 23, 2025) was prepared by APEX/Advantage Geoservices, completed at a 0.006 oz/ton Au marginal cut-off using $2,400/oz Au and $28/oz Ag, and is based on 886 historical drillholes (1973–2012). Metallurgical testwork confirms amenability to conventional heap leach processing (Merrill-Crowe). The project also exhibits potential tungsten-copper-molybdenum mineralization beneath the gold-silver zones (not explored since 1984).

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
Silver
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.
Assumptions
- Presented values are denominated in currency of the country where the company is headquartered. Values like market capitalization might differ from the values visible in other parts of the page, where the currency is always USD.
