I provided a sticky which indicates 3 things from the links provided at the bottom of the page. 1. Jorge Lopehandia has Certified Domain to the areas which cover Mina Pascua. 2. On the margins of Tesoro 1 1/30 to Tesoro 12 1/5 it says "property of Jorge Lopehandia". 3. Jorge Lopehandia has unencumbered title.
