Your calculation of the ore from the Alexandra mine is as follows:
If you look in the ibox, the historical report of the Alexandra mine says the shaft was "85 feet deep, vertical, and 6 by 10 feet in size", not 85 x 85 x 85. Is the 85 x 6 x 10 correct? If not, where did the 85 x 85 x 85 come from? If the 85 x 6 x 10 is correct, that makes the volume of ore removed 0.0083 times the original calculation, which makes the ore value around $290,000, not $34M. I didn't check the rest of the calculations which I assume are correct.
