Arlington Rapallo 2025: Simon Catt Interviews Hayden Locke, CEO of Marimaca Copper

At Arlington Rapallo 2025, Simon Catt sits down with Hayden Locke, Founder and Driving Force and CEO of Marimaca Copper (TSX: MARI), to talk about one of the most exciting new copper discoveries in Chile.

Marimaca’s share price is up 150% since last year’s Rapallo — and with good reason. Haydn explains how the company is advancing its flagship MOD project, while simultaneously uncovering a potentially Tier 1 copper discovery at Pampa Medina. With permits expected by the end of 2025, a strengthened team including industry veteran Giancarlo Bruno, and strategic interest circling, Marimaca is positioning itself at a pivotal inflection point.

Topics discussed include:

• Why Marimaca’s share price surged 150% in a year.
• The scale and potential of the Pampa Medina sulphide discovery.
• Development plans for the MOD project and first production timelines.
• Strategic options: build, partner, or sell.
• The role of Greenstone as major shareholder and potential exits.
• Adding industry heavyweight Giancarlo Bruno to the board.

This conversation captures a company on the cusp of transformation — balancing the excitement of discovery with the discipline of moving into development.
