Australian-listed Hillgrove Resources has announced the final results for its 2009 trench sampling program at Pahandanjal Prospect on the island of Sumba in Indonesia's Nusa Tenggara Barat province. The program confirmed the presence of large zones of low grade gold mineralisation enveloping multiple vein sets of medium to high grade gold mineralisation.
Many of the earlier trenches had to be extended further into the andesitic host rock and some are still not closed off due to the depth of the intermittent scree cover. Broad low to medium grade gold anomalism has been identified in trench results from the Western Vein system including 34m at 2.07g/t Gold and 3.85g/t Silver(FT5EXT), 7m at 1.05g/t Gold and 1.93g/t Silver (FT6EXT), 17m at 1.16g/t Gold and 1.79g/t Silver (FT7EXT).
Other broad low grade mineralisation identified in trench results from the Eastern Vein System including 78m at 0.8g/t gold and 4.27g/t Silver (FT21A), 52m at 0.51g/t Gold and 5.23g/t Silver (FT20) and 24m at 1.06g/t Gold and 3.82g/t Silver (FT23). Additional low grade mineralisation discovered further east including 70m at 0.53g/t Gold and 3.49g/t Silver (FT24).
The discovery of broad zones of low grade mineralisation along with narrower high grade shoots confirms just how prospective Pahandanjal is and Hillgrove has commenced preparations for drill testing which is expected to occur in March/ April.
