What Are Minerals?

Minerals are naturally occurring, solid inorganic substances found in the Earth’s crust. They form through geological processes and are extracted through mining. Ontario’s minerals are used in everything from construction and energy to electronics and electric vehicle batteries.

Why Minerals Matter

Minerals provide the raw materials essential to modern life and economic development. Ontario’s mineral sector supports:

Clean energy (e.g., lithium, nickel, cobalt)
Construction (e.g., aggregates, stone)
Manufacturing and automotive (e.g., iron, zinc)
High-tech and electronics (e.g., rare earth elements)
Jewelry and finance (e.g., gold, silver)
Ontario’s Critical Minerals Strategy identifies priority minerals needed for clean technologies and strategic manufacturing — especially important for electric vehicles, batteries, and decarbonization.

To effectively seize this opportunity… we need to get our critical minerals out of the ground, processed and shipped to the factory floors.

Note: The availability of minerals varies by region and geology. Exploration activity continues to uncover new deposits, especially in Northern Ontario.

Critical Minierals in Ring of Fire Regions

Chromite

Chromite is the only major source of chromium, essential for stainless steel and aerospace alloys. Ontario's Ring of Fire hosts some of the world's largest undeveloped chromite deposits, critical to Canada's clean tech supply chain.

About Chromite

Cobalt

Cobalt mining is vital for modern tech, with deposits in Ontario's Ring of Fire. Its value surged due to use in lithium-ion batteries and clean energy, making it key for low-carbon transition.

About Cobalt

Copper

Copper mining is crucial, providing a conductive metal with reddish-brown hue. Symbolized as Cu, it's vital for electrical infrastructure and Canada's green economy, key for global electrification.

About Copper

Gold

Gold, mined for its value, is prized for conductivity and malleability. Symbolized as Au, it's essential for jewelry and electronics, remaining Earth's most coveted element.

About Gold

Nickel

Nickel, a strong silver-white metal resistant to corrosion, is key for stainless steel and batteries. Symbolized as Ni, it’s vital for electric vehicles and clean energy. Ontario’s Sudbury Basin and Ring of Fire are major global nickel sources.

About Nickel

Palladium

Palladium (Pd), a rare silvery-white metal from the Platinum Group, is vital for catalytic converters and hydrogen fuel tech. It’s a strategic metal in Canada’s clean energy shift, found in Ontario’s Sudbury Basin and Ring of Fire.

About Palladium

Platinum

Platinum (Pt), a rare metal in the Platinum Group, is vital for catalytic converters and hydrogen tech. Found in Ontario's Ring of Fire, it's prized for durability and high heat resistance.

About Platinum

Vanadium

Vanadium (V) is a strong, corrosion-resistant transition metal used to harden steel and in vanadium redox flow batteries. It’s an emerging critical mineral for clean energy, found in Northern Ontario near the Ring of Fire.

About Vanadium

Zinc

Zinc (Zn) is a bluish-white metal vital for anti-corrosion, galvanizing steel, alloys, and clean tech batteries. It’s the world’s fourth most used metal. Ontario has major zinc deposits, with promising exploration in the Ring of Fire.
