Long-time Papua New Guinea minerals explorer Frontier Resources Limited (ASX:FNT) has identified four gold prospects within close proximity of the historic Tolukuma gold mine.
The four targets, which lie to the east of Tolukuma, have been recommended for follow‐up during an independent analysis of historical surface sampling and geological mapping.
The Diakoku, Ijav and Evese gold prospects were explored by previous miners Newmont and Tolukuma Gold Mines (TGM) and occur along the deepest Ijav fault.
The Hoyu prospect occurs on same NNW structure as the Soju gold system. Diakoku was discovered by Newmont in 1989 while following up anomalous BCL drainage anomalies from 1988 in the Auga River headwaters region. Follow‐up of a spot 0.34 g/t Au soil anomaly resulted in discovery of a one to 10m wide structure from which trench results included 3.6m @ 2.95g/t Au, including 1.6m @ 5.2g/t Au.
Trench sampling by TGM exposed a 9.0m wide vuggy silicified zone that averaged 2.62 g/t gold and 250 ppm Cu over 9.0m. TGM interpreted the Diakoku structure as high sulphidation style copper‐gold mineralisation possibly located above a porphyry system at depth.
The Evese Prospect occurs 12km SE of the Tolukuma mine site and was selected for sampling by TGM in 2007 on the basis of coincident aeromagnetic, Landsat and topographic anomalies.
Historical fieldwork included 23km of creek geological mapping and 52 rock chip samples which were uniformly anomalous in gold between 0.1 & 0.42 g/t Au. Results of sampling and mapping indicate Evese to be a volcanic centre and further fieldwork including soil sampling has been recommended to Frontier by an independent geological consultant.
