MINERA SAN CRISTOBAL S.A. (MSC; head office La Paz, Bolivia) operates the San Cristóbal open-pit mine in the Potosí Department of south-western Bolivia.
The mine produces silver, lead and zinc. Sumitomo Corporation owned MSC from 2009 (having bought out Apex Silver Mines' remaining interest) until February 2023, when San Cristobal Mining Inc. — a private company incorporated in British Columbia, Canada, backed by Ocean Partners UK, Trafigura, Crescat Capital and Haywood Securities — completed its acquisition of MSC and the Sumitomo subsidiaries holding its equity (Sumitomo Corporation, 2023; San Cristobal Mining Inc., 2023). No single majority owner within that group is disclosed. It sells zinc-silver and lead-silver concentrates to smelters, not refined metal.
Verbatim from the dossier's “What they do” section — sources on the company profile.
No production footprint is recorded in its dossier yet — its HQ country is 🇧🇴 BO, a registration fact, not a production or sales claim. We say so rather than guess.
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 (producer; co-product carried in concentrate). Silver is paid for inside both concentrates. It is not a trace additive here but a major value contributor, so silver-policy and price exposure are material.
Zinc (producer; bulk product). Zinc-silver concentrate is the mine's largest stream by tonnage. Its value depends on smelter access and treatment charges, and on any export or processing policy that affects concentrate flows.
Also listed in its dossier but not platform-scored: lead — no supply-risk series is tracked for it here.
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

Prohibits raw mineral exports unless 30% value-addition achieved domestically; affects Chinese mining companies (dominant in Nigerian critical minerals sector), Western offtake agreements, and all foreign-invested mining JVs; builds on existing eMC+ digital cadastre and mandatory value-addition plans introduced Nov 2024; could force processing-plant investment or suspension of raw mineral shipments from Africa's most populous economy; RMRDC = Raw Materials Research and Development Council (the sponsoring agency)

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.

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 2 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.
Every tracked material is on the supply side — the strategy here is positioning, not substitution.

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.
