The float is just under 190,000,000 shares, 85mil (give or take) are still restricted as of Feb 14, 2013.
There have been several private placements, most notably to a Barry Honig, stock promoter, his office suite compadre', Dr. Philip Frost of TEVA Pharmaceuticals fame, and (Barry's brother to a lesser degree.)
This company was formerly called SAGEBRUSH (symbol SAGE). Around Feb 2012 timeframe, the company divested many non-mining assets and liabilities, and changed their name a/w/a symbol to PGLC.
Hope this helps.
