About Capstone

Capstone owns and operates two high grade copper mines and has an
advanced high grade copper-zinc development project, all located in
favourable mining jurisdictions in North America. The Cozamin Mine is a high
grade, relatively shallow, mechanized underground copper mine in Zacatecas,
Mexico, with significant by-product credits of zinc, lead and silver. The
Minto Mine is one of the world's highest grade open pit copper-gold mines,
and is located in the Yukon, Canada. Both mines have recently undergone
significant production expansions and the mines are forecast to produce a
total of 90-100 million pounds of copper in concentrate in 2010 at a total
cash cost of approximately US$1.10 to $1.20 per pound of payable copper, net
of by-product credits and selling costs. In addition, Capstone owns the high
grade Kutcho Copper Project in British Columbia, Canada, which is being
advanced towards a production decision, and could produce significant
by-products of zinc, silver and gold. Capstone aims to grow both organically
through its existing projects, and through mergers and acquisitions.
Capstone's growth ambitions are backed up by a successful track record of
growth through both avenues, and supported by a strong balance sheet and
significant equity investments.

The TSX does not accept any responsibility for the adequacy or accuracy
