RE:Was that a 100 million lb hole?

(124 m high, 50 m wide, 50 m thick, 3 specific gravity, 6.35%, do the math).
There are no doubts left as to who has the biggest, best new discovery in the last 25 years in the basin.
Drilled at a dip angle of -76 degrees, the true width is 30m and vertical extent 120.3m.
So 30m strike * 30m width * 120.3m depth * 6.35% * 2.75 tonnes/m^3 * 2204.62 lbs/tonne = 43mm lbs in hole 62 alone.
Total for A2 ultra high-grade subcore actually drops to 160mm lbs per my estimate. Again this is just for the ultra high grade subcore within the A2 high grade core. FWIW, I estimate total inventory at a minimum 260mm lbs.
I calculated ore density as follows: 2.4 t/m3 for gneiss and 8.0t/m3 for pitchblende; 93.65% gneiss and 6.35% pitchblende; (93.65%*2.4) + (6.35%*8.0) = 2.7556
