Normally a 20 percent random sample would result in a highly reliable result from a purely statistical standpoint.  For instance political polling takes only a minimal percentage to produce plus or minus 1 percent reliable predictions 80 percent of the time.

The huge difference with diamond samples as I see it would be (a) the diamonds are not equally distributed and (b) size difference has a huge impact on the value of the outcome. 

A few large stones can sway the carat count dramaticly.

A major indicator to those of us on the sidelines, in my view, will be if they continue with the remaining 400 tons and continue further to the 5000 ton level.

Proceeding will not guarantee a mineable deposit.  Ceasing forthwith would be indicative that results have been overwhelmingly disappointing.

The company must be at the critical stage in terms of decision making as that ice road will soon be at the point of being able to accommodate loads that will allow movement of the remaining 400 tons.  It doesn't have to all be moved at the same time.  Given that we are talking only 50 KM, it would be no problem to move things in very small amounts to Yellowknife where they could be gathered on larger trucks for eventual transport to Grand Prairie  Those trucks as well would have load restrictions due to the Ice Bridge at Fort Providence (if that still exists)

Fun times folks.  Lets hope we all have the opportunity to hang on during one of those meteoric rises.

Onward and Upward.
