of a gossan on a hill top. Exploitation began in 1913, followed by a copper rush in the region. Since 1961, many exploration programs have been carried out for base metals and in 1970, the number 70 ore body Pb-Zn was discovered at Matahambre. Currently, copper exploitation continues, and in the Castellanos deposit, a
Zn isotope compositions of all samples except those from the three profiles are presented in Table 4. The average 66 Zn value of the bed-rocks is 0.44 0.02, which is identical to mine tailings 0.42 0.02. Zn-ores have an average 66 Zn value of 0.23 0.03, which is
