That would be the clay alteration zones identified in the Aster imaging data, which they probably got here: http://www.geosciencebc.com/s/2005-038.asp

The planned drill program changed to "

Approximately 2,500m (five holes) of drilling is planned with the last two holes of the proposed drilling program contingent on results "

They will look at the core on site and see if there is enough visible copper mineralization over a long enough length to justify drilling the last two holes. We won't get any assay results for a month or two after the drilling is done and only if released through the JV meetings.
