They can't rely on some 90 year old cores or data.
Which don't exist. It is ludicrous to think that core has been gathering dust in someone's shed for 90 years, just waiting for a near-broke penny stock shyster to announce they have "rediscovered" the core. It is comical that anyone believes this.
And you are right about the "huge gold deposit". There is no credible evidence at all that ACRL, a non-disclosing POS penny stock, is sitting on a huge gold deposit. Again, comical that anyone falls for this crap.
