Ann: Low pH Field Demonstration Update, page-46

Lance has some of the lowest Calcium level areas around there, some were saying they thought it had high levels but they never read the whitepapers and just speculated. Based on the pre-operational water samples from 46 production or injection wells within the two operating mine units, the production zone aquifer has moderate TDS levels (1,200-2,500mg/L), low calcium concentrations (2-9 mg/L) and moderate sodium (430-870 mg/L), bicarbonate (400-680 mg/L),and sulfate (400-1,320 mg/L) concentrations (Strata 2015, 2016b)Yes they changed the oxi and this will get the other 2 tests to 2.0 ph currently .03 away .

A petrographic analysis of a core sample collected in 1977 shows that it contains less than 1percent carbonate (Strata 2011b). This is supported by additional core samples collected by Strata since 2010, in which carbonate concentrations in the mineralized sandstone range from 0.001 to 1 percent (Knode 2017). A carbonate value of less than 1.5 to 2percent is considered appropriate for mining with a low pHlixiviant (IAEA 2001).

Make sure you do real research because there are a few people here that short pen and were posting lies trying to get people to sell, those same people pump and dump other stocks and they got diluted out with pen years ago. I only post facts they only post lies about Pen. They have never been able to post anything about my facts.
