Native leaders from a remote Northwestern Ontario reserve were sent to jail...yesterday for opposing mining on their traditional lands, as an opposition leader blamed the Ontario government for failing to resolve the conflict... The natives are in a dispute with Platinex... The court issued an order last fall allowing Platinex to begin drilling, but when company representatives landed in Big Trout Lake..., natives and an aboriginal...officer threatened to arrest them if they proceeded... The Platinex mining claims are not on reserve land, but rather the larger traditional native lands. The company has said it tried to involve KI in the process and offered financial compensation... Last month, Paula Sherman and Robert Lovelace, co-chiefs of the Ardoch Algonquin First Nation, were sentenced to six months in jail for contempt of court in similar circumstances [involving Frontenac Ventures].
