Karina Vein Extension (PDF, 365 KB)
Iberian recently announced results of deep underground drilling on a portion of the Mine known as the Karina Vein which indicated a high-grade zone extending to depth. The contribution of veins, with their generally higher grade mineralization, is important as a head grade regulator.
Results of a diamond drill campaign have confirmed continuity up to 265 meters below sea level, or 90 meters below Level -175, and are summarized in the following table:

The onsite supervision of the diamond drill program was done by Carlos Rodriguez, Superintendent of Geology at Condestable (since 2005) under the supervision of Mike Newbury, P.Eng. as Qualified Person. The diamond drill program produced 71 core samples of 4.0 meters long on average. The cores were cut by saw and 50% sent for assay to the secure Condestable lab onsite for analysis. The assay procedure was Atomic Absortion Spectometry (Aqua Regia Digestion).The lab undertakes batch duplicates and replicates for quality control in their analytical procedures. Check samples were sent to ALS Chemex Laboratory Group.
