Geology


Antakena's Resource Estimate incorporates the results of 43,837m drilled at Elenita, in 276 holes - half of which were drilled in the latter of 2008.

Apoquindo successfully validated the historical data by drilling 2,131m or 15 twin holes. Subsequent drilling at Elenita was used to selectively infill missing areas and to explore new ore zones at the periphery, especially to the South, East and Northeast. This drilling has been largely successful, but is not yet completed. Currently the drill holes are distributed along 50m NW-SE sections and spaced at 20-30m increments. Due to the low dip angle of the mantos, the vast majority of the holes are vertical.

The current unconstrained mineral inventory is represented by the following grade-tonnage tables:
