The company made an all-cash proposal last month to acquire First Coal for approximately C$147m ($149m).
First Coal is now a wholly-owned subsidiary of Xstrata Coal Canada, and its acquisition provides Xstrata with access to coking coal exploration leases in the Canadian province of British Columbia.
First Coal is engaged in the exploration and development of metallurgical coal properties in north-eastern British Columbia, and it holds licenses or applications for licenses in respect of about 94,000 hectares in the Peace River Coalfield.
