Latin America Mining M&A — Frequently Asked Questions

A typical path is: identify the target (concession, exploration project or producing mine) → sign NDA and letter of intent (LOI / MOU) → due diligence (technical, legal, market) → transaction structuring (share purchase, asset purchase or joint venture) → negotiation and signing → government approvals and closing.

ECB supports each stage with origination, brokering and advisory, and can design a complementary offtake agreement alongside the deal.

Copper: Chile, Peru; lithium: Argentina, Chile, Bolivia (the "Lithium Triangle", ~68% of global lithium resources); iron ore and rare earths: Brazil; gold and polymetallics: Argentina, Peru, Brazil and others.

The right opportunity depends on the mineral, the project stage and each country's investment environment — ECB screens targets to your focus.

Common structures include: direct equity acquisition, joint ventures (JV), project finance in exchange for offtake rights, and offtake + prepayment arrangements.

In recent years foreign (including Chinese) mining M&A in the region has concentrated on gold, copper and lithium. ECB focuses on connecting Asian capital with quality regional targets and offtake opportunities.

Concession / exploration project: lower entry cost and price, but longer development timeline and higher geological and permitting risk.

Producing mine: clear cash flow and lower risk, but higher valuation and fewer available targets.

The choice depends on the investor's risk appetite, cost of capital and time horizon.

It typically covers: technical (resources/reserves, JORC or NI 43-101 reports, mine plan), legal (title to mining rights, permits, environmental approvals, community and indigenous agreements), financial and tax, market (product specifications and route to sale), and counterparty and compliance (KYC/AML).

Independent inspection bodies (such as SGS and equivalents) are commonly used to verify quality and quantity.

RIGI (the Incentive Regime for Large Investments, Law 27,742 of 2024) offers companies investing more than US$200 million in a single project up to 30 years of tax, customs and foreign-exchange stability, along with tax and import-duty benefits.

Mining (including lithium and copper) is one of its covered strategic sectors and has attracted numerous lithium and copper project applications, materially reducing long-term investment uncertainty.

Key risks include: policy and regulatory change, permitting and environmental timelines, community and indigenous relations, foreign-exchange and capital controls, infrastructure (power, water, ports, logistics) and price volatility.

Thorough due diligence, stability mechanisms (such as Argentina's RIGI) and reliable local partners can partly mitigate these.

An offtake agreement is a contract in which a buyer commits to purchase part or all of a mine's output over an agreed term and on agreed terms.

In M&A and project finance, an offtake both secures the route to market and improves bankability, and — often combined with a prepayment — can be a way for an investor to enter a project. ECB can design the M&A transaction and the accompanying offtake together.

It depends on the complexity of the target. From signing the LOI to closing, a producing-mine deal may take several months, while transactions involving exploration projects, complex approvals or cross-border structures can take longer.

Due diligence and government approvals are usually the main factors determining the timeline.

ECB provides: asset origination (concessions, projects and producing mines), due diligence (technical / legal / market), transaction structuring, and connection to international capital and offtake agreements. We focus on Latin America, connecting Asian capital with regional opportunities.
