BENGF was over $8 at one point(now .25), and was shut down by low copper and gold prices. It was the 4th largest miner in the world in the '80s, with the likes of Asarco, Cyprus Amax and Phelps Dodge.
Since that time the Echo Bay spent $25MM in drilling out the KingKing mine, only to have unrelated financial problems, with te KingKing reverting back to BENGF.
If the KingKing were already open, this would be 10X higher than it is, and that is what the stock price will start to reflect as copper and gold prices remain higher.
You have might have $70 max to look forward too in NEM (top of next channel), or about a .5X.
