PNG Copper Inc. reported that the drilling of hole DOD005 on Drill Section 10040N at the Doriri nickel-palladium-platinum prospect resumed on June 3, 2022 after a delay awaiting the arrival of spare parts from the Philippines and Australia for the manportable ID200 drill rig. Mineralization was intersected from 46.40 m to 64.20 m (17.8 m downhole width). DOD005 was terminated at 74.00 m in footwall peridotite on June 15, 2022.

Core logging and sampling is presently underway. Core samples will be dispatched to Australian Laboratory Services in Townsville, Australia, for analysis. Gold, platinum and palladium analyses will be completed by standard 30 gm lead collection Fire Assay followed by Inductively Coupled Plasma Mass Spectrometry.

Nickel assaying (including copper and silver) will involve a four-acid digest including hydrofluoric, nitric, perchloric and hydrochloric acids in Teflon tubes. Analyses will be completed by Inductively Coupled Plasma Optical (Atomic) Emission Spectrometry. The drill rig will now shift to a separate drill pad for the commencement of holes DOD006 and then DOD007.

Doriri Epithermal Ni-Pd-Pt Prospect: Doriri is a low temperature accumulation of nickel, palladium and platinum located in the mafic and ultramafic rocks of the Mt Suckling massif in southeastern Papua New Guinea. There is no other documented mineral occurrence with a similar geology. Temperatures of formation of nickel-rich chlorite, rhythmically interlayered with magnetite in the deposit, are in the range 100-220oC, classifying it as an epithermal deposit.

The mineralisation has an average width of 10-15m and has been previously mapped over a strike length of 520m. It remains open ended in both directions. Mineralization crops out at the surface and remains open at depth.
