The GOG report said 40 million ounces so with our 50% share means only 20 million to us.
Diluted by our outstanding shares means at most ten cents to the share price. Hardly worth of notice among the daily fluctuations.
The 200 is what is expected and until that is officially reported it is just talk.
It would mean about one and a half billion dollars in additional value but distributed over 240 million shares means $6 additional per share. You will only see a small fraction of that reflected in the share price.

I am no expert, I do not own any GOG shares so take little interest in that side. Finally I do not do much research but rely on reports from a few folks that do actual foot work at ECU mine site.
Read some of the posts at Stockhouse's ECU forum, especially old ones from Coach.
