Investment Highlights

Positioned in critical minerals supply chains

Brazil IAC REE Discovery
Confirmed

Magnum has confirmed ionic adsorption clay-hosted rare earth mineralisation at the Azimuth REE Project in Brazil.

High-Value Magnet REE
Strategic

Early results highlight meaningful MREO distribution, including magnet rare earths used in electrification, defence, robotics, and clean energy supply chains.

Exploration Footprint
~85 km²

The Piracanjuba North target sits within an approximately 85km² geophysical footprint, with first-pass drilling suggesting potential lateral continuity.

Pathway to MRE
Nov 2026

A 200m × 200m grid drilling programme is planned to advance toward a JORC-compliant Mineral Resource Estimate, targeted for November 2026, subject to results.

Why Rare Earths, Why Now?

Rare earths are essential to the technologies shaping the next decade.

Rare earth elements underpin electrification, permanent magnets, robotics, defence, renewable energy, advanced manufacturing, and high-performance electronics. As demand for these technologies grows, secure and diversified rare earth supply chains have become a strategic priority globally.

Permanent magnets & electrification

Magnet rare earths such as Nd, Pr, Dy, and Tb are critical to EV motors, wind turbines, and high-efficiency electronics.

Ionic adsorption clay deposits

IAC-hosted rare earths may offer near-surface mineralisation and simpler processing characteristics compared with some hard-rock systems, subject to test work.

Brazil as an emerging jurisdiction

Brazil is increasingly recognised as an important rare earth exploration region, with established critical minerals districts and supportive geology.

Core Growth Story

Brazil: A New Rare Earths Growth Platform

Magnum's Brazil rare earths portfolio includes the Azimuth REE Project and Palmares REE Project, located across highly prospective regions of south-central Brazil. Recent work has confirmed ionic adsorption clay-hosted rare earth mineralisation at the Piracanjuba prospect within the Azimuth Project.
