Preliminary figures for 2001 indicate that the total value of Ontario’s mineral production was $5.63 billion, down slightly from $5.87 billion in 2000. Lower nickel prices were primarily responsible for the decline in the value of metals, while nonmetals were up slightly in 2001. The contribution of the three commodity groups included metals ($3.4 billion), nonmetals ($2.1 billion) and fuels ($130 million; structural materials are now included with nonmetals). Ontario was responsible for about one-third of Canada’s metallic minerals and 28% of the nonmetals.
Ontario maintained its status as the lead jurisdiction in Canada in terms of value of non-fuel mineral production. The province accounted for 29% of Canada’s non-fuel mineral production value in 2001 compared with 31% in 2000, and had a margin of more than $2 billion over the next closest jurisdiction.
The five highest value metallic minerals produced in Ontario in 2001 were nickel ($1.118 billion), gold ($1.052 billion), platinum group elements ($514 million), copper ($450 million) and zinc ($104 million).
In 2001, the top two commodities produced in Canada were gold and nickel; Ontario provided 63% of the country’s nickel production as well as 50% of its gold production.
Final exploration and deposit appraisal expenditures for 2000 totaled $117.9 million. In contrast to the national trend, preliminary estimates for 2001 decreased slightly to $113.6 million. Expenditures are expected to increase to $126.7 million in 2002.
Spending intentions for 2002 indicate that Ontario will lead all Canadian provinces and territories in exploration and deposit appraisal expenditures for the third consecutive year with 25% of Canada’s total expenditures.
Preliminary figures for 2001 indicate that $308.6 million was spent on mineral exploration, deposit appraisal and mine development expenditures in Ontario. This total consists of $74 million (24%) for exploration, and $39 million (13%) for deposit appraisal, while mine development expenditures are estimated at $195 million (63%). Forecasts for 2002 estimate that total expenditures will decline to $301 million. The decline is attributable to reduced spending on mine development, which is on a downward trend that began in 1998.
In 2001, spending by Ontario’s junior mining companies increased by more than 45% to $40 million while spending by Ontario’s senior mining companies decreased by more than 15% from 2000 to $74 million. Forecasts for 2002 indicate that spending by Ontario’s junior companies will increase by more than 5% from 2001 to $42.3 million and spending by Ontario’s senior companies will increase by 14% to $84.4 million. Ontario’s senior companies account for about two-thirds of Ontario exploration expenditures, a decline from over 75% in 1999 and 2000.
The number of mining claims in good standing in Ontario at the end of 2001 was 184,433, an increase of 13.6% from 2000. The increase can be attributed to the ongoing interest in gold as well as continued interest in exploring for diamonds and platinum/palladium.
De Beers Canada Exploration Inc. continues to explore and conduct advanced exploration on and around the Victor diamond project, 90 km west of the community of Attawapiskat.
