Highlights

Gold is the most sought-after mineral in Ontario, topping the charts with exploration spending of $659 million or 67% of the province’s total exploration spending in 2022.

In 2022, 3.9 million troy ounces of gold valued at $5.4 billion were produced in Ontario totaling 41% of Canada’s gold production by value.

Ontario is home to 16 producing gold mines and 13 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.

Demand for this strategic commodity is expected to increase as the market for batteries to power electric vehicles and other clean technologies grows.
