Agincourt has started drilling at its recently acquired Martabe gold and silver project on North Sumatra in Indonesia.
Approximately 15,000 metres of drilling is planned for the highly prospective Kapur Gambir district located 30km south east of the main Martabe Project area. A second drill rig will be mobilised mid next month to start drilling at the Purnama East, Baskara East and Pelangi deposits within the Martabe district. Also under way is the analysis of 17,000m of drilling, previously undertaken by Newmont, but not incorporated into the Martabe Resource model. This will result in a resource upgrade for the Baskara East and Pelangi deposits and is expected to be completed shortly. The Kapur Gambir district is characterised by a 5 sqkm geochemical footprint of similar size to the 5.3 million ounces Matabe district. Numerous highly prospective targets within the district including Kapur, Natas, Tegar and Gambir remain essentially untested with no drilling being completed at Kapur Gambir since 1998, despite the identification of a district scale Low Sulphidation vein system. Of the limited drilling that has been completed significant mineralisation was identified at Kapur at drill hole ASKD008 with 0.6m @ 8.0 grams per tonne gold from surface) which has not been followed up. Several reasons have resulted in this area remaining undrilled which include the complete refocussing of exploration to Martabe after its discovery. However extensive field work completed over the last two years including Hoist EM, Induced Polarisation (IP), soil sampling, detailed mapping and rock chip sampling has laid the ground work for an extensive driling program at these highly prospective targets. The Kapur prospect was originally identified from highly anomalous stream sediment sampling results of 88ppb gold and 389ppb gold. Normandy drilled two holes, one of which intersected 10.6m @ 8 grams per tonne gold from surface, including 2.9m @ 27.7 grams per tonne. Subsequent trenching at the surface of the hole determined that the mineralization was hosted in transported colluvium. A large hill located immediately north of the Kapur prospect drilling of has been identified as the likely source of the mineralised boulders. The Kapur soil anomaly is characterised by a coherent plus 200ppb gold anomaly covering an area in excess of 1000m by 500m. The centre of the soil anomaly is located in the valley south of Kapur hill and is thought to be caused by mineralized colluvium that has shed from Kapur as identified in ASKD008. A similar geometry exists at the 4.4 million ounces Purnama deposit where first pass exploration drilling missed the orebody due to tageting the central part of the soil anomaly that represented the down slope colluvium derived from the Purnama orebody. In situ rock chip results have identified primary mineralisation on Kapur hill up to 15.3 grams per tonne gold associated with silica replaced bladed clacite and saccharroidal drussy textures indicative of a high level boilng zone in a low sulphidation vein stockwork system. Additionally, Pole-dipole IP has defined a large coincident circular resistivity and chargeability anomaly immediately north of ASKD001 associated with silica-clay alteration and hydrothermal breccia. Drilling of IK001 at Kapur started mid-October and is the first of a 21 hole, 2700m initial program in the Kapur Gambir district. The Tegar prospect is characterised by highly anomalous geochemistry with outcropping low sulphidation veins assaying up to 184gpt gold and 189gpt silver. Soil sampling over this area has defined a coherent plus 200ppb gold anomaly over 500m long by 100m wide area (Figure 5). A coincident Pole-dipole IP resistivity anomaly is hosted by hydrothermal breccia within andesitic rocks. The Tegar prospect has never previously been drilled and will be targeted immediately after the initial program at Kapur. Mapping and rock chip sampling has defined a low sulphidation vein system at Natas with the main Natas vein sporadically outcrops over a 1.5km strike length. Limited rock chip and two trenches have identified colloform banded and drussy textured veins up to 8m wide as well as bladed calcite assaying 10.3 grams per tonne gold. Further IP will be conducted at Natas next month before first pass drilling. |
