Has anyone done any possible valuations? Below is my attempt based on current gold reserves only. But keen to get thoughts from others?

	Column 1	Column 2	Column 3	Column 4	Column 5	Column 6	Column 7
0	Current reserves (gold only)
1	oz AU	US$	NZ$			Number of shares	$ per share
2	399000	$501,144,000	$686,498,630	total revenue		2076995855	$0.3305
3	399000	$35,910,000	$49,191,781	in ground value @$90	2076995855	$0.0237
4	399000		$287,008,000	Cost to extract nz$692 per oz +10.9m cap costs	2076995855	$0.1382
5			$399,490,630	Profit		2076995855	$0.1923

p.s. I also did some figures for 600K oz and 1m oz gold, but need to check some of my assumptions
