If they bought us for 1 billion for example, say teck shares are up at at $30 or more

About 18:1 share exchange

if they bought 30 million shares around $10 = $300 mil to purchase our 25%

If they bought at $15 - 450 million to buy our share, buy at $20 - 600 million, etc

Can you imagine the deal they get if for 300 million...then they have no obligations to fund etc and can sell our 25% for over a billion.  Or maybe they sell 50% for over $2 billion and use that money to fully pay for their half of developing the mine

So 50% ownership of a long life fully operational shaft creek for teck with no money spent....that would be impressive 

 I hope my math checks out :)
