Guess you did not take time to read the excerpt from the JV agreement (which is shown on Copper Fox website) -

Teck will:

1. pay a total of $60 million in three direct cash payments to Copper Fox - $20 million was paid on signing the Joint Venture Agreement; 

2. fund 100% of costs incurred prior to a production decision up to $60 million; 

3. fund any additional costs (in excess of $220 million) incurred prior to a production decision, if required, by way of loan (at an interest rate of prime +2%) to Copper Fox to the extent of its pro rata share, without dilution to Copper Fox's 25% joint venture interest".

Therefore, Teck will provide all financing needed to fully develop production!
