In 2023, Ontario produced 62,501 tonnes of nickel shipments valued at $2,547 million (59% of Canada’s nickel production by value).
Platinum Group Elements (PGE)
In 2023, Ontario produced 81% of Canada’s PGE
Vanadium
Ontario has vanadium exploration potential in Southeastern Ontario.
Chromite
Highlights
Chromite is the major ore mineral of chromium.
Chromium is the stainless in stainless steel and is used in many manufacturing processes because of its resistance to rust, shiny appearance and very high melting point.
Current estimates suggest the Ring of Fire has multi-generational potential of chromite production and significant potential production of nickel, copper and platinum.

Cobalt
Highlights
An estimated 1,700 tonnes of by-product cobalt shipments worth $162 million were produced in Ontario in 2023. This represents 56% of Canada’s cobalt production by value.
118,527 tonnes of cobalt shipments have been produced in Ontario between 1904 and 2023.
Cobalt is a critical element in lithium-ion batteries and other clean technologies. Demand for this strategic commodity is expected to increase in the coming years as the market for electric vehicles grows.
The town of Cobalt, Ontario, known for its significant historical silver and cobalt production, is a national heritage site and is considered the birthplace of Canadian hard-rock mining.

Gold
Highlights
Gold is the most sought-after mineral in Ontario, topping the charts with exploration spending of $599 million or 63% of the province’s total exploration spending in 2023.
In 2023, 2.8 million troy ounces of gold shipments valued at $6.5 billion were produced in Ontario totaling 43% of Canada’s gold production by value.
Ontario is home to 17 producing gold mines and 12 significant gold exploration projects.
With more than 30 mineral deposits each having more than 500,000 troy ounces of gold (measured and indicated resources inclusive of reserves) located in traditional camps and beyond, Ontario has plenty of resources for the future.

Graphite
Highlights
Ontario has several advanced exploration projects and active graphite exploration programs.
The Black Donald Mine, located approximately 100 kilometres southwest of Ottawa, produced 77,000 tonnes of graphite between 1896 and 1954 which is approximately 75% of Ontario’s graphite production to date.
Graphite has been used traditionally in high-temperature lubricants, electrical motors and batteries. New uses are being discovered for graphite including lithium-ion batteries, solar power and electric vehicles.
