# Are these calcs right

1. 256 Posts.
Have been running a slide rule over a hotcopper favourite AVL, to look at purchasing some. I have come up with the following simple calcs, can anyone see anything glaringly incorrect with these?

14,000 tonnes of copper per annum
\$US1600 per tonne for copper
And there are 2205 pounds per tonne

They have said it will cost them \$US0.36 per pound to make the copper
so 14,000 tonnes * 2205 pounds per tonne = 30,870,000 pounds
30,870,000 pounds * \$us0.36 cost per pound = \$US11,113,200

They can sell 14,000 tonnes at \$US1,600 per tonne
14,000 tonnes * \$US1,600 = \$US22,400,000

So it will cost them \$US11,113,200 to mine and they will get \$US22,400,000 when they sell it.
\$US22,400,000 - \$US11,113,200 = \$US11,286,800

They have borrowed \$US4,500,000
So interest will be about \$US450,000 per year
and they will give 10% of profit to the locals (schools, hospitals, etc) \$US1,128,680
So profit per year should be \$US9,708,120, about \$AU16,738,137 at exchange rate of \$0.58

They have about 167,000,000 shares on issue, and they are trading at \$0.10.

So \$AU16,738,137 profit divided by 167,000,000 shares is about \$0.10 earnings per share.
