Coppermoly extracts high-grade copper results from Nakru samples
THE DRILL SERGEANT: Coppermoly Limited (ASX: COY) has released final assay results from rock float samples collected on the company’s Nakru exploration licence (EL 1043) on New Britain Island in Papua New Guinea.
The company explained the assays are for previously announced samples that contain high-grade material and were listed previously as containing greater than two per cent copper or two per cent zinc.
Coppermoly collected fifteen rock float (talus debris) samples at the Nakru 2 Northwest and Nakru 4 prospects located approximately 500m to 1000m northwest from known mineralisation at Nakru 2 and Nakru 1 prospects in February 2015.
The three samples from Nakru 2 Northwest (NK2-0011 to NK2-0013) each assayed greater than two per cent copper and together with highly anomalous gold, silver, zinc and molybdenum, which the company interpreted to confirm previously reported high-grade float samples in.
Coppermoly is of the opinion the samples may indicate a new parallel mineralised zone north west of Nakru 2.
Six of the twelve float samples (NK4-014 to NK14-025) collected from the Nakru 4 prospect assayed greater than one per cent copper with two greater than two per cent.
The company considers these samples could also indicate a new parallel mineralised zone to the north of Nakru 1 prospect.
“All of the samples with elevated copper contain sulphides with little or no oxidation,” Coppermoly said in its ASX announcement.
“The dominant sulphides are pyrite and secondary chalcocite with some chalcopyrite.
“The float samples are considered to have a local provenance as the topography is relatively subdued limiting downslope movement and the samples are relatively unoxidised suggesting recent exhumation.
“The sulphide mineralisation is associated with strongly developed silica + sericite + clay altered rho-dacite breccias.
“Similar rocks host mineralisation at Nakru 1 and Nakru 2 prospects.”
Coppermoly claims the results of the samples further extend the potential of the Nakru prospect to host a large copper and gold deposit.
The company is now planning a detailed surface mapping and sampling program to determine the full extent of the mineralised system at Nakru.
