Fangk, the initial drilling was a large number of shallow holes and trenches to find areas of mineralisation to target future drilling programs using a cheaper drilling method over a wider area. The drilling method they used was affected by the water levels in the ground which has lowered the mineral recovery so they have moved to a different type of drilling which should give more accurate results and drilled some deeper holes to target areas that showed significant results in the last round of drilling. Hopefully that makes it a bit clearer for you.
