In July 2013, continuing with the discovery of the Quicay II porphyry copper-gold deposit, Corporación Minera Centauro resumed the exploration works at the Quicay mine. Accordingly, 19 diamond drillholes were executed in the Quicay pit area and surroundings, amounting a total of 13,070 meters.
Considering the previous evidences found in the Pacoyán area with the discovery of the porphyry copper-gold deposit (Quicay II), the first interpretation stage of Quicay I was based on the data obtained from the geochemistry, geophysics and drilling campaign. The latter was carried out with the goal to identify a similar porphyry copper-gold deposit as Quicay II.
In order to conduct the diamond-drilling campaign, Corporación Minera Centauro factored in the data obtained in 2012, from the geochemistry survey, together with with the systematic sampling through canals. Likewise, additional surveys were incrorporated in order to plan the dimond-drilling campaign: the geophysical interpreting of IP magnetometry executed by Arce in 2004, the Magnetometry survey carried out by Quantec in 2012 and the IP Method Titan executed by Real Eagle Explorations in 2013. Accordingly, the drilling platforms were positioned based on the high chargeability and low resistivity mapping result from the latest magnetometry study.
Through the progress of the diamond-drilling campaign, several stock pulsations, ditches and host rocks were identified. Volcanic andesites at the pit and surroundings are the host rocks.
The exploration area of the andesite porphyry deposit Quicay I, has been defined as 300 x 300 metres and 500 metres of depth; these results are based on the data obtained from the drillholes executed at the central area and the latest IP geophysical survey conducted by Real Eagle Explorations.
