Hi Bkz
Share cap for years ending June 30 were as follows:
Share on issue from financial statements note
2012: 202m
2013: 379m
2014: 502m
2015: 502m
You can compare market cap positions of slr at various share prices at times. So if $4 was in Jan 12 for example it would be comparable to $1.61 (202m/502m x $4)
