Codelco–Anglo Andina–Los Bronces plan: integrated mine design notes for planners
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
Codelco’s Andina Division and Anglo American’s Los Bronces copper operation have secured all required free-competition approvals for their Joint Mining Plan, including clearance from China’s State Administration for Market Regulation (SAMR). The agreement, originally signed in September 2025, enables coordinated long-term planning of adjacent orebodies in central Chile, with potential for shared infrastructure and optimised pit and underground sequencing. For mine planners and geotechnical teams, the sign-off removes a key regulatory constraint on integrated slope design, haulage layouts and tailings strategy across the combined footprint.
Technical Brief
- SAMR approval was required because both Codelco and Anglo American sell copper into the Chinese market.
- Clearance process explicitly treated the Joint Mining Plan as a concentration operation under Chinese competition law.
- Authorisation scope covers coordination of extraction, processing and marketing, not only mine planning activities.
- SAMR review focused on potential impacts on refined copper and concentrate supply competition.
- Approval conditions reportedly do not impose structural remedies such as asset divestments or capacity caps.
- No additional notification was required to Chilean antitrust authorities beyond earlier domestic competition clearances.
- Timing of SAMR sign-off aligns with the parties’ target to operationalise the agreement during 2026.
- For other multi-operator districts, SAMR’s decision provides a precedent for joint planning approvals involving Chinese offtake.
Our Take
Codelco’s recent MoUs with Microsoft and XCMG in our coverage suggest that the Andina–Los Bronces Joint Mining Plan is likely to be implemented against a backdrop of accelerated digitalisation and fleet modernisation across its Chilean operations.
The need for SAMR clearance underlines how important Chinese market access has become for Codelco and Anglo American, echoing other Chile copper pieces in our database where Chinese regulatory or offtake dynamics are now a core strategic consideration.
