Rock chip sampling and trenching has resulted in a new gold zone being identified at the Majapahit prospect of Hillgrove Resources’ Sumba project. Best assays from this work are 6 metres @ 12.3 grams/tonne gold and 3.8 metres @ 21.52 grams/tonne.
Hillgrove holds 80% of PT Fathi Resources which holds the 750sqkm IUP on the island of Sumba. Hillgrove is responsible for sole funding and management of all exploration and development activities up to a decision to mine.
At Masu in the southeast of the IUP, rock chip sampling, trenching and drilling have confirmed the presence of epithermal vein-hosted gold mineralization at several prospects. Initial scout drilling has been completed at Karipi prospect and has delineated near-surface gold mineralization associated with a complex low sulphidation epithermal system.
The drilling has shown that gold is hosted in veins, vein breccias and stockworks which commonly show both tectonic and hydrothermal features. Mineralization at Karipi is open down dip and down plunge. The northerly plunge direction of the main vein trends towards an untested IP resistivity geophysical anomaly. Best results are 5 metres @ 1.59 grams/tonne gold and 14.7 metres @ 1.26 grams/tonne.
Follow-up mapping and sampling of regional target areas has identified a number of new targets, including Majapahit where sampling of quartz vein-breccia systems has returned significant gold grades. The results are considered significant as they represent an entirely new mineralized system with high gold grades formed within steeply dipping veins. This discovery confirms that the Masu corridor remains highly prospective and that the potential to delineate economic quantities of gold mineralization remains very strong.
Exploration will continue at Majapahit and Big Sulphur, preparing for drill testing in the near future. Karipi is evolving into a very interesting deposit, and with Hillgrove’s growing understanding of the geology of the Masu Corridor, the company is excited about the prospect of delineating additional gold deposits.
Meantime, initial scout drilling of 10 holes for 4911 metres at the West Delta target of the Birds’ Head project in West Papua has been completed with assays confirming widespread molybdenum mineralization and associated elevated copper values consistent with a near-porphyry environment. Best results are 46 metres from 59 metres @ 149ppm molybdenum, 15 metres from 166 metres @ 132ppm, 14 metres from 331 metres @ 298ppm, 67 metres from 279 metres @ 145ppm and 11 metres from 210 metres @ 121ppm.
