RE: XTR: Colin Bird interview, Tues, 2.3.21: "BUSHRANGER-TRANSFORM ANY CO."2 Mar 2021 16:21
From the various RNS's, I have the following for the 3 completed holes to date:
H1: 1,235m with mineralisation from 330 = 950m
H2: 899.4m with mineralisation from 130m = 769.4m
H3: 975.5m with mineralisation from 290m - 685.5m
So clearly not a cube and won't be cuboid. So let's assume instead that it is 'ellipsoid' i.e. a bit like a squashed/elongated/deformed sphere. The (basic) formula for calculating the volume of an ellipsoid is: 4/3 x Pi x ABC
A, B and C being the radius of the length, height and width. Punch in the above numbers as our A,B and C and I get 263m cubic meters. Multiply by 2.7 to get the tonnage and that's 707,400 mt of mineralisation.
If we then assume our mineralised rock has a Cu Eq content of 0.45% (which CB seems to think is possible) then that equates to 3.18mt of Cu. Based on the John Cornford estimate of 40p for 2mt, we would therefore looking at over 60p per share. And that was before the recent increases in the price of copper.
And let's also not forget that the thing does seem to be getting bigger, with talk of multiple porphyry's, multiple cores and even buried cathedrals filled with riches. Adding just a bit to the width and depth at the fat end of Jabba will make a significant difference. Lots more holes needed to build the 3D picture and, of course, assay results to start confirming the content but it is looking very good.
