Project information
As at 31 December 2024
Description
As at 31 December 2024
The Company's 100%-owned flagship, a past-producing polymetallic silver complex located approximately 76 km southeast of the city of Durango, Mexico, comprising 40 contiguous mining concessions covering 38,128 hectares. The complex consists of five underground mines (Rosarios, La Rosa, San Jose, Quebradillas and San Marcos) and the Quebradillas open pit surrounding a 2,000 tpd processing plant configured as parallel 1,000 tpd flotation and 1,000 tpd cyanidation circuits, treating polymetallic oxide and sulphide ore (silver principal, with lead, zinc and minor gold) to produce doré, a silver-rich lead concentrate and a zinc concentrate. Acquired from First Majestic Silver on August 14, 2023, the complex has been on care and maintenance since September 2019 after producing 34.3 million silver-equivalent ounces between 2005 and 2019. On October 21, 2025 rehabilitation began (Dynamic Engineering on plant rehab; SRK reviewing the restart plan), the sulphide flotation circuit is being expanded from 1,000 to 1,250 tpd via eight new flotation cells, underground rehabilitation is preparing Quebradillas, San Marcos and Rosarios, and a 6,000 m underground drill program began January 14, 2026, targeting a potential Q2 2026 restart. The restart decision is not supported by NI 43-101 reserves, a PEA, or a pre-feasibility/feasibility study; no mineral reserves have been established. Metalla Royalty & Streaming retains a 2% NSR.

Description
As at 12 April 2013
A 100%-owned advanced exploration property held through subsidiary Golden Tag Mexico S.A. de C.V., among the largest undeveloped silver assets in Mexico. It comprises four mining concessions (91.65 hectares) in the Municipality of Cuencame, Durango State, approximately 75 km southwest of Torreon and 12 km northeast of Penoles' Velardena mine, within the prolific Velardena Mining District which has produced silver, zinc, lead and gold for over a century. Mineralization occurs as quartz-calcite veins and the bulk-tonnage Fernandez Zone, typical of polymetallic intrusive-related skarn and low-sulfidation epithermal systems carrying silver, lead, zinc, gold and copper. The property has been advanced through seven phases of surface diamond drilling totalling 43,491 m to the end of 2022. A mineral resource estimate was completed by SGS Canada in an NI 43-101 technical report published in April 2013; SGS also recognized additional target potential of 20-50 million tonnes grading 100-150 g/t silver-equivalent, a conceptual target that is not a mineral resource. Golden Minerals Company retains a 2% NSR royalty. The Company intends to conduct in-fill drilling and to evaluate potential synergies with La Parrilla. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Copper King

Project information
Description
An early-stage copper-silver (lead-zinc) exploration property held through Silver Storm's 51.82%-owned subsidiary Silver Predator Corp. (SPD), a Canadian junior explorer focused on Nevada and Idaho, USA. The property targets bedded (disseminated) and vein-style copper-silver-lead-zinc mineralization in the Revett Formation and overlying St Regis Formation, analogous to Montana's Troy, Montanore and Rock Creek bedded deposits and to vein mines of the nearby Coeur d'Alene District such as the Lucky Friday Mine. A June-October 2024 diamond drilling program from two pads completed core holes CK-1 (to 853.4 m) and CK-2 (to 450.2 m); results did not encounter grades adequate to support bulk underground mining of the bedded horizons or vein intercepts of sufficient size and grade, with the best bedded interval (CK-1, base of the St Regis Formation) estimated at 7.4 ft true thickness grading 20.75 ppm silver and 0.275% copper. SPD has no formal plans for additional drilling; mapping and drilling results are being used to project further targets. No NI 43-101 mineral resource has been defined.

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
Zinc
Lead
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.
