Can somebody explain a few things
If daniel is 7000m x 2000m x 27m avg. The resource would be 378 million m3 of gravel
By my calcs thats approx 1,900,000 hundred tonnes.
What is an economic resource?
At 2.0 cpht it would hold 3.8 million carats.
What grade do local producing deposits hold?
What price do they fetch?
How does a 500 tonne bulk sample give you an accurate measure of grade?
