"Do proper diamond grade and valuation exist?" We are in the process of finding that out. "Will the "custom mill and process" be done on site?" I would prefer it to be but if we can save money hauling ore out that route will be followed. "Is Sturgon lake "road" accessible by truck?" Yes. "Is the actual lake connected to the kimberlite formation?" The Sturgeon lake kimberlite is immediately north of and adjoining Sturgeon Lake. Thank you in advance for any insight to these questions. Cheers
