The project can further expand to 100 million tonnes per year beyond the tenth year and the mine life is estimated at 34 years. 

Osisko rejects Goldcorp’s $2.6bn takeover offer


Canadian mining company Osisko Mining rejected Goldcorp’s C$2.6bn ($2.4bn) takeover offer, claiming that the offer was financially inadequate and not in the best interests of shareholders.

Osisko is the owner of Canadian Malartic mine in northern Québec and said that after thorough consideration and discussion, its board dismissed the hostile bid, saying it significantly undervalues the world-class mine and the company’s portfolio of high-potential projects in North America.

Goldcorp’s premium offer and the transaction multiples implied by it are both below the relevant precedents. It implies a multiple of 1.0x versus previous multiples of 1.8x for large-scale producers.

Osisko stated that the current offer implied a 15% premium at the time of announcement and is significantly less today.
