PRE-MINING ACTIVITIES
Part of the activities of the dealers is the excavation ofShaft 1, for some time the mining
area has been working hard to informal miners (artisanal), which as shown in Table 1,
with the help of 25 mills homemade balls, are capable of producing up to 64 grams
of gold per day, with a value of U.S. $ 3,213 in the current quote, if we project these
revenues for a month of work, would represent a profit of U.S. $96,390, wasting yet
the 50 % of gold due totheir low recovery.
