Seems there are multiple factors at play.
First, is this a scam or a legitimate mine? When is say legitimate I simply mean does Mexus intend to get material out of the ground and process it. I say that is yes. If it were simply a scam or pump and dump I don't think it would be a seven year process with multiple partners and staging equipment for the sole purpose of trying to deceive.
Second, how much gold is there? This is very shaky at best. Studies done by the company instead of third party, projecting consistent concentrations based on concentrations at one depth, work that is not comprehensive in scope, etc.... Big caution flag if not big red flag.
Third, why did Argo leave? Crappy assay reports and not much gold to mine? Crappy development plan for both the mine and the property? Couldn't trust Mexus leadership? Wanted/needed to prioritize funds in other projects? I have called them and have not spoken with anyone yet...will keep trying.
Who is MarMar? I can't find anything on them online.
Fifth, the property is in the general vicinity of other productive mines.
Professionalism...not necessarily a prerequisite but the Web page, structure of the company and other factors are highly concerning.
For me it seems unlikely this is a compete scam but it also seems to be highly speculative at best.
January will be an interesting month.
