I thought some may find this interesting where bolded. Its about how the locals were picking up gold bearing rock to take to the plants to sell while the first exploration work was going on by SLI.

Except for one report by Minera Reliance del Peru S.A.C, reliable data on the

Tesoro property is not available. Obviously, considering the quantity of pits that

were mapped during the present campaign (Figure 2), the presence of goldbearing

quartz veins has been known for some time. And even while the

exploration work which is the subject of this report was taking place, there were

three groups of informales (about ten people altogether) bagging auriferous vein

material for processing at nearby plants. Most of the informales working on the

property were from Otapara, and all were more than pleased to discontinue

activities in return for employment during exploration and assurances that, if future

development took place, they would be first on the hiring list.
