If CDU mines at 3% and at 4.5MTA that will effect share price.
Some hope for first year of full production over 5%.
WM has made hints.
Now if the option's are in cents and all the ducks line up and full production is within two years then the percentage gain may be astronimicall. Many will take a punt.
Within the two years it will be known what the grade is and what the real throughput is. If you have less than 50 cents to lose and the optimists are right you could end up very rich.

If the pessimists are right you lose all.
