Soto Norte

A Sustainable, Community‑integrated Gold Project

Located in the historic California–Vetas mining district of Colombia's Santander Department, our Soto Norte operation is one of the most attractive gold opportunities in the Americas.

A 2025 prefeasibility study outlines a long‑life underground mine with robust economics, lower operating costs, and leading‑edge environmental and social safeguards, including a downsized 3,500 tpd plant that reserves over 20% of capacity for local community miners and a design that collects, treats, and safely returns all mine water to protect regional supplies.

Operational Focus

We are finalizing environmental studies and preparing to apply for an environmental license in H1 2026.

Our Approach to Responsible Development

We’re focused on generating substantial long‑term value for shareholders, communities, and government partners, while maintaining the highest standards of safety, water protection, and environmental management.

Community Processing Capacity

Our processing plant provides 20% excess capacity (750 tpd) to facilitate local, small scale miner formalization.

Minimal Water Use and Surface Tailings Storage

Our recycling system allows 96.5% water reuse. Almost half of the produced tailings to be stored underground.

Local Employment

During peak construction, we will create about 2,300 jobs, with long-term operations sustaining about 675 direct employees.

No Cyanide or Mercury

Our processing facility will not use cyanide or mercury.

Community Engagement Model

Our structured engagement model empowers communities to identify priorities and propose initiatives.

Environmentally Sound Operations

Our use of a rope conveyor reduces truck traffic, dust, and spillage.

Water Protection and Improvement

Our operation is designed to protect local watercourses.

Filtered Tailings Facility

We use best-practice designs according to globally recognized standards.

Contract Mining Partners

Our Partnership-driven Model

We integrate local small-scale miners into a formal, safe, and environmentally responsible framework through our Contract Mining Partners (CMPs). This allows us to support thousands of jobs while securing reliable mill feed. Our CMP model allows us to formalize artisanal mining, streamline permitting, and expand technical support.
