I guess you are new here or you choose to ignore real DD.
First, MMC (MexicoMiningCenter.com) is not a Mexican government website and is not associated with the government in any way. Did you notice that it is a .com and not a .mx site?
Also, it is a paid for inclusion site - that is you pay them and they put in anything you send them. Did you notice the banner ads - how many government sites have banner advertising?
The Mexican Ministry of Economy (which governs the mining industry) has a database you can check all of the mining concessions and SRGE is nowhere to be found.
So MMC means nothing - SRGE has no mining concessions - wishful thinking is a bad investment strategy.
