Goldcorp (T.G) extends Osisko (T.OSK) takeover offer, still in play despite Yamana deal

VANCOUVER - Vancouver-based Goldcorp is extending its takeover offer for Osisko Mining until 5 p.m. on April 15.

The announcement came a day after a rival offer from Toronto-based Yamana Gold Inc., which wants to buy a half-share of Osisko's mining assets with support from Osisko's board of directors and two of Canada's largest pension funds.

Yamana's offer values Osisko at about $3.4 billion.

Goldcorp says it will continue to examine the rival offer and conduct its due-diligence investigations of Osisko and its main asset, the Canada Malartic gold mine in Quebec.
