Ann: Update on Area 51 Exploration Program , page-4

hi seagull thanks for sharing your Email. ..

marble is not that hard , on the Mohs hardness scale it is 3-4 .

limestone & Dolomite have the same hardness and could be scraped and no overburden ether

here is a marble crusher with about the same capacity your notes refer to .

regards the price that was mentioned $2500to $3000pt. only super large flakes of high purity could fetch that sort of price ,

the whole thing looks a bit early to consider as serious figures
and the profit margin of 30$ pt of ore processed don't match up ether ,
and he called it a Metal ?


so ,, marble no problem imo. the rest is early acquisition hype but good potential
