What they make, where they produce, the materials that matter — then what is coming, what it would do to the business, and the moves available. Sector: mining metals. Company profile →
Compañía Minera Poderosa S.A. is a Peruvian precious-metals producer operating a single underground gold mine complex in the Pataz district of La Libertad, northern Peru, on the gold-bearing quartz-vein system of the Pataz batholith.
It has been in production since 1982 and is one of Peru's larger domestic gold miners, reporting output above 300,000 ounces of gold in 2022. The company is vertically integrated through to finished metal. Ore is treated at two plants — Marañón, at Vijus, which began at 120 dry tonnes per day in 1982 and had reached 800 t/d by 2019 with an expansion to 1,000 t/d planned, and Santa María. Both recover metal by cyanide dissolution followed by precipitation and smelting, and Poderosa has added a chemical refinery at the Marañón unit producing 99.99%-purity gold and silver bars on site rather than shipping precipitate to a third-party refiner.
Verbatim from the dossier's “What they do” section — sources on the company profile.
This is where Compañía Minera Poderosa S.A. produces — approximate output shares from its dossier — not where it sells. Sales geography is not yet in our corpus for any company, so we cannot compute exposure to measures that bite on where products ship: an extraterritorial re-export rule follows the shipment and its material content, not the factory. Where such a measure touches its materials, the policy sections below flag it — but its sales-side incidence is not computable yet, and we say so rather than substitute the production map for it.
Of everything in its products, we track the critical inputs — the materials whose supply is concentrated in few countries, policy-exposed, or hard to substitute — because those are the ones a single measure can move. Each carries its role in the product, quoted from the dossier's own exposure note.
Silver — *co-product, upstream supply position*. Confirmed rather than inferred: Poderosa's Marañón chemical refinery produces silver bars at 99.
Zinc — *bulk consumable, industry-standard inference, NOT Poderosa-confirmed*. The published process route (dissolution → precipitation → smelting) is Merrill-Crowe, which cements dissolved gold and silver out of pregnant cyanide solution onto **zinc dust**; zinc is consumed continuously and stoichiometrically at any plant running that route,…
The dossier also records the materials it investigated and rejected — the list above is narrowed deliberately, not cherry-picked. Its own words:
Scope. The non-critical remainder of the bill of materials — structural steel, polymers, glass and the like — is not tracked here because it is not supply-constrained: this section covers the constrained inputs, which is where policy risk concentrates, not a full bill of materials.
The top 4 are ranked mechanically — what the instrument does (its transmission class: an export ban is not a reporting duty), × how close to law (stage-derived likelihood band, never a probability) × how much of your tracked bill of materials it touches. Each unfolds as a chain: trigger → what it hits → the response the instrument actually calls for. A measure touching a material you produce can be an opportunity, not a threat.

Reduces maximum idle-concession period from 30 to 15 years (initial production deadline unchanged at 10 yr; penalty extension cut from 20 yr to just 5 yr); eliminates irrevocable legal status of mining concessions for first time in Peruvian law history, making concessions revocable by administrative authority; introduces higher annual fees and stronger production/investment requirements; threatens legal certainty for Peru's undeveloped copper and silver project pipeline — Peru = #2 copper, #4 silver, #1 lead, #2 zinc globally

This changes the form of what Nigeria exports, not whether you can buy: raw/unprocessed exports are restricted while domestically processed material stays available — that is the measure's own mechanism. Your Nigeria-origin raw feed becomes processed-only; the route is a value-added purchase or a Nigeria processing partner, not a supplier switch.
Secondary — only if you need to avoid Nigeria entirely: zinc supply outside NG is 🇨🇳 CN 39%, 🇵🇪 PE 14%, 🇦🇺 AU 10% (shares renormalised after removing NG).

The Energy and Mineral Resources Ministry (ESDM) and Ministry of Finance announced May 11, 2026 that the implementation of higher tiered royalty rates under Government Regulation (PP) 19/2025 — covering copper, tin, nickel, gold, and silver — is postponed indefinitely pending development of a "mutually beneficial formulation"; the already-filed PP 19/2025 (2025-04-11) established a tiered royalty regime that would have raised effective royalty burdens for large-volume miners; the postponement relieves immediate cost pressure on Freeport McMoRan (copper/gold — Grasberg), Vale Indonesia (nickel), PT Timah (tin), and other major operators; the delay also signals continued investor-consultation sensitivity in Indonesian mining fiscal policy following industry pushback

1 of 11 filed an explicit in-force stage; the rest (flagged below) default from an absent stage: field, not a filed assertion. Each links to the register entry with its primary source.
For a material it buys, a restriction tightens supply and raises input cost — a headwind. For the 1 it produces, the same restriction supports pricing — a tailwind. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).
Its customers sit in ev batteries, permanent magnets, ev motors, wind turbines, defence… — read via the graph's critical minerals node, the nearest equivalent of its sector. A measure supporting those sectors supports demand for this company's products; one restricting them puts that demand at risk. The sign shown is the mechanical read — click through to judge whether a measure protects or constrains the customer.
For each bought material: the ex-controller producers a procurement team can actually reach, from the alternatives map (derived 2026-10-07), viability-gated — each name carries its deployment status (with the verbatim dossier phrase it rests on), a capture check against the measure being escaped, and any contracted-capacity evidence. Deployable-now names sort first; a developer with zero tonnes is shown demoted, never dressed up as a switch you can make today. Tradability is inherited from the listing layer, never guessed.
This company sits on the supply side of silver. Restrictions by 🇲🇽 MX push buyers toward ex-MX producers — the strategy is to be visible where those buyers look: the silver chokepoint page and the watchlist.

lib/policy-transmission.ts): an export prohibition in the measure's name/text → supply restriction; a raw/unprocessed-export limit or local-processing mandate → beneficiation (form change, not unavailability); reporting/disclosure/due-diligence language → compliance obligation; tariff/trade-remedy language → import cost; subsidy/fast-track/relaxation language → support; investment-screening/M&A language → investment control. When the text carries no signal we fall back to the action-type default and label the chip inferred; when neither exists the card says so and derives no response — we never assert a class the evidence doesn't support.lib/iptm-material-country-production.ts; mining stage preferred, refining as fallback — the stage and source year are in each figure's hover text). Ex-issuer supply removes the ISSUING country and renormalises the remaining listed shares (so they sum to 100% of what's left) — alternatives to the country making the rule, never a default ex-China list. Where the issuer holds no measurable share, the card says so plainly instead of implying supply loss.lib/alternative-viability.ts): each named alternative carries a deployment status — operating / ramping / restarting / development / unknown — derived from word-boundary signal phrases in its own dossier (“operating since 1896”, “restarting the … mine”, “FID taken”), and the verbatim matched phrase is shown as the basis so the claim is auditable; a dossier with no signal stays unknown, never guessed. Any evidenced production date is quoted verbatim (“first production targeted H2 2029” → “no tonnes before 2029”) — we never synthesize one. A measure whose own text claims extraterritorial / re-export / de-minimis / foreign-direct-product / percentage-of-value scope triggers the origin-switching warning above the list: such a rule follows the material, not the seller, so a foreign-made alternative can still be captured. Same-issuer register actions targeting an alternative's country and material mark it may be captured, with the entries linked. “Capacity partly committed” lines quote the dossier verbatim — we hold no structured free-capacity numbers and never imply a utilisation figure.How MacroLens tracks this for you.
