A planned 7-hole drill program is testing the downdip continuity of high-grade stratiform massive sulphide mineralization at the Dairi project in North Sumatra, Indonesia.
The third hole of the 2000 program, 24D, was collared 100 metres north of hole 18 and intersected 4 metres grading 8.2% zinc, 5.1% lead and 7.7 grams silver, beginning at a down-hole depth of 48 metres. This was followed by 10.2 metres grading 17% zinc, 12.2% lead and 19.1 grams silver, starting at a depth of 64.8 metres.
Hole 24 was drilled about 80 metres updip of hole 23D, which cut 3 metres of 2.6% zinc, 1.5% lead and 3.2 grams silver, immediately followed by 14.5 metres grading 15.9% zinc, 9% lead and 8.6 grams silver, starting at 104 metres down-hole.
The first hole of the program, 22D, was drilled 100 metres downdip of hole 18 at an angle of -85 and intersected a previously reported 2.7 metres grading 29% zinc, 22.2% lead and 21.4 grams silver, followed by a second interval of 19.1 metres grading 16% zinc, 7.54% lead and 4.8 grams silver.
Annax is currently drilling hole 26D, which is testing the mineralization downdip from hole 1. Hole 25D intersected a 5-metre section of sulphide vein stockwork, 100 metres updip of hole 18, which suggests that the main sedimentary-exhalative (sedex) horizon may have been displaced by faulting.
