Hi Will, Would you like to speculate on a grade and ave carat value for the mini bulk being processed? I added Vaughn's calculation assumptions in. Lots of interesting calculations to think about. Thanks to both of you for spending the time to display your assumptions and calculations about eventual cashflows and profit in cyberspace. We continue to hurry up and wait(gggggggg) Changes, additions and corrections are welcome. The TWG.t spring 2002 Jackson Inlet minibulk guess the diamond values contest.

Very interesting discussions about mining costs, revenues and cash flow per share. But I have a few questions. Usually, the cost of mining a deposit is function of the rate of mining which is dependant on the capex, the later being the result of optimizing the return function (usually choose the mining method and rate giving the best ROC). According to you, what will be the capex up there and the return on capital? Cash flow per share or EPS if you use the later, is function of the number of shares outstanding. How will be finance the developpement of this project? JP
