Maybe the answer is in this statement, for the 5/9 ann
Approximately 2,500 metres of RC and diamond drilling (Figure 1) has been designed to determine geological controls and geometry of the high‐grade zones of mineralisation in WDRC005.
It does not say anything about specifically targeting mineralisation; but you'd still have to think that they would dearly want to find the primary zone and hit good grades and widths of chalcopyrite.
Also, we don't know how much of the 2500ms will be RC and how much will be diamond. The ann does not tell us that, but looking at this pic below, there are 10 holes. The deepest one is vertically about 280ms below the surface. Diamond?
The ann does however tell us that the co-funded diamond hole will be deep. That hole is not shown here I reckon. Maybe that went down first? Would that make sense?
