Mount Crater Gold Mine in Papua New Guinea

Crater Gold Mine is located in the western part of Eastern Highlands Province in Lufa District,
adjacent to the eastern border of Simbu Province bordering Kramui Nomane District. It is centered
50 Km southwest of Goroka, the capital town of Eastern Highlands Province.

The closest airstrip is the Guasa Airstrip. From Guasa airstrip it will take you about 2 - 3 hours walk up the steep hills and along the fast flowing rivers. The site is ussually assessed by shopper.

ML510 was granted to Anomaly Limited in November 2014 to carry out a small scale underground
mining and processing operation at Crater Mountain.

Prior to the Mining Application and due processes were followed for granting, there was an exploration license EL 1115 which was known as Nevera and Nimi Prospects. The exploration could have started long ago back in the 1980s and various  PNG National geologists as well as foregne geologist can recall this prospect. The EL 1115 started in 1994 when the exploration licence was granted initially to MACMIN and then jointly explored by BHP. It was then to Anomaly Limited. Anomaly then tirelessly continued the exploration until the mineral resource was defined and further intended to apply for a mining lease to developed the ore body which was defined.

Mineralisation is typically confined to veins and thus dictate the Mining Method to be sub-level caving. The operation utilities hand-held  rock drills and jack picks. Broken ore is transported via mini rail cars to surface for processing.

Tailings discharge from the mill is collected in a sump where solids settle and the water overflow is
channelled into a second sump to further settle any silt and clear water overflows out to the nearby
creek. The solids in the sumps are harvested periodically and stockpiled for further processing at a
later stage.

Thus, it is believed that mine waste is managed within the vicinity and less environmental impacts are anticipated in this operation.
