PAPUAN Fold Belt minerals explorer Frontier Resources Ltd is off to a mixed start to its latest drilling campaign.
Frontier reported that it had completed four holes totalling 161.3 m at the Swit Kai Central Lower Horizon at its Bulago project and five diamond core holes at East Creek.
The Swit Kai holes are targeting flat lying gold mineralised zones, while the East Creek drilling was following up a 3.0m wide zone that graded 45.2 g/t gold in previous jackhammer channel samples.
Frontier chairman and managing director, Peter McNeil, said there had been some difficulties encounter at Bulago-Swit Kai.
“The drilling program at Bulago -Swit Kai has been challenging but proceeded well after the initial mechanical (brittle drill chuck seals) issues. The drilling from Pad 1 was underwhelming because we couldn’t intersect the zone in holes 1 and 2; it is a difficult area to be able to get the required inclination and azimuth for the rig relative to either of the mineralised orientations.”
However McNeil, said the core drilling program at East Creek had proceeded very well.
The company reported that the brief geological logs available from each hole indicate significant megascopic sulphide mineralisation and quartz veining has been intersected in the core in the upper parts of the holes. Initial analysis also identified that intense quartz sulphide mineralisation and veining is concentrated along the contact zone of competent black mudstone and intrusive, primarily in the mudstone.
The company remains confident in Swit Kai where it believes there is excellent strike continuity potential, which can now be easily drill accessed relative to the topography. Gold in soil anomalies along trend to both the east and west of the Lower Zone, indicate a strike length of more than480m.
Mr McNeil said that gold anomalies in drainages to the west of Swit Kai indicate its unevaluated strike potential and drainages to the N and NW have never been sampled.
“The region has excellent mineralisation potential, with strong radiometric and aeromagnetic anomalies that require substantial evaluation,” he said.
Mr McNeil said that many new targets have been proposed from the topographic evaluation and its refinement is ongoing.
Aeromagnetic data has suggested that the best immediate large /regional target is the next zone upslope from Swit Kai, while another new zone to test is downslope from Swit Kai where there is very strong zinc and lead, plus gold anomalies in grid based soil sampling and a rock outcrop sample to 37 g/t gold.
