摘要
A ground magnetic survey was conducted on the Kusi mineral prospect, Papua New Guinea, to provide insights into the magnetic properties of the mineralisation and help define drill targets for an exploration programme. The results of the survey suggest three distinct magnetic zones： （1） a magnetic high zone covering the northern portion of the survey area; （2） a northeast-southwest trending magnetic low zone occupying the southern portion and （3） a possible buried intrusive body separating the magnetic high from the low magnetic zone. The results of the survey suggest that drilling is concentrated on the zone of low magnetic response, and the periphery of the interpreted intrusion is adjacent to the contact to the limestone defining the mineralisation style of the two zones. A further ground magnetic survey is required to determine the western limits of the low magnetic zone.
