great expectations for brooking?

From data already available,
Suggest that BOD already have a fair idea what to expect at Brooking.

Of recent years, the number of microdiamonds in a pipe (either kimberlite or Lamproite) has assumed greater importance as a predictor of quantity of commercial size diamonds present. The SFD (Size Frequency Distribution) tends to be constant in a specific area.

Rio Tinto is now using this method to estimate its ore reserves.

Simply, they use the number and weight of the microdiamonds, usually from each sieve size to extrapolate the predicted number and size of diamonds expected up to 10 carats.
Usually it requires a couple of drill samples, combined to give over 300 microdiamonds, with at least 2 macro diamonds over 0.6 mm. The larger the concentration of microdiamonds and the more large microdiamonds and macro diamonds the greater the predicting ability.

So we have
HIGH CONCENTRATIONS of microdiamonds.
7 macro in 119 - equivalent to 17 in 300: so excellent on this parameter.

LOTS OF NICE LOOKING STONES, clear and some yellows/ chips.

All we need now, is size of the pipe to give a pretty clear indication of what we have here.

And I reckon, even from Google Earth and probably from other data, that our BOD have a pretty good idea where we are headed.

And I would also bet that RIO is watching CLOSELY !

CHEERS, bbd.
