Have you actually checked the ore grade in jalisco with the companies that actually mining?
I suspect not from what you are posting.
Goldcorp the largest mining company in Mexico has 3 active mines with the following grades are 0.37 grams/ton, 0.74 g/t and 1.60 g/t.
Goldcorp with all of its financial resources could have purchased CM years ago but it has been mined out. Plus, as is stated in the Tumi report the underground mining conditions are too dangerous with the open stopes (in the US this is generally referred to as "old works" where there was previous mining), plus as the Behre-Dolbear report stated the reserves of higher grade ore in the underground mine was too low to continue.
The SRGE drill program numbers have been fabricated - if not where is the lab and who was the "Qualified Person" who was reviewed the drill program and the contents of the press release.
As usual with SRGE there is nothing that can be verified.
