RE:RE:RE:RE:Tenoriba p-p-p-p-p-p-pump job Actually, Yale Resources were unable to keep up with option payments on Tenoriba on August, 2011, see pg 27/155 here (https://www.mammothresources.ca/i/pdf/2014-02-18-Tenoriba-Property-Report-TRA.pdf), quote:
'On July 2009 Minera Alta Vista S.A de C.V., the 100% Mexican subsidiary of Yale Resources Ltd. of Vancouver, Canada signed a purchase option agreement with the Tenoriba property owners. The agreement included USD$2,000,000 in cash payments over a four year period. On August 2011, after being unable to make the first semester cash payment to the owner of the property, under the terms of the option agreement between the parties due to the challenges in raising equity capital in the North American equity market, Minera Alta Vista was forced to return the property to the owners.'
The current management (including the Geo and CEO) were not appointed until later (CEO, Thomas Atkins on April 12, 2012) afterwhich Mammoth signed an option agreement for Mammoth in July 2012. Perhaps Yale was poorly managed, but it was a different company to Mammoth, and further a different management team.
