ore calculation

Its a bad day all around, yikes!! but my back of the envelope calcs on ore and ounces is as follows-

-Quartz is 2.6 times the density of water and water is 1000k per cubic meter
-We have 3 quartz veins which are at least 70 meters long (open at depth) by at least 1 meter to 4 meters wide
-Strike length in the pit is at least 40 meters and extends on either side of the pit, they go for another at least 20 meters to the east and west
-We have maybe 10g/tonne average grade
Therefore-
70(known vein depth) x 3(holes) x 2.5 (average width) x 100 (estimated strike length) = 52,500 cubic meters
Therefore-52,500 x 2.6 = 136,500 tonnes @ 10 g/tonne/30 g per Au ounce = 45,500 ounces x $1,300 = $59.15 million worth of gold- importantly all within 50 metres of the surface easy open pit, or sale to nearby producing mine

Just my guess so DYOR, but IRG looks cheap...
