So I can almost estimate the top line revenue side based on the numbers I have seen.

100 Million tonne orebody
$US800 / tonne Spodumene Concentrate price.

What is the conversion factor of 1 tonne of Spodumene rock to Spodumene concentrate?  I would presume it is some factor less than 1 !?

Trying to Google this metallurgical information and I am still feel uninformed.

I am trying to determine top line revenue potential. 100M * some factor? * $US800 = $US X

Once we have determined that I would be interested in trying to estimate profit per tonne of ore body.

While every ore body is going to be different based on location, what would be the usual rule of thumb expectation of cost to extract 1 T of Spodumene Concentrate?

Profit / tonne = ($US800 - Production Costs / tonne)

I did find this:

Am I reading this right?  SYA have a resource of 10Mt and we have a resource of 80-100Mt?

$US300 per tonne?
