ASX Announcement
Date: 1[st] November 2012
ASX Code: COY
EXPLORATION RESULTS AT THE MAKMAK TENEMENT SHOWS POTENTIAL FOR IOCG STYLE MINERALISATION
Coppermoly Limited (ASX:COY) (“Coppermoly”) is pleased to announce preliminary field results confirming mineralised rock samples collected from its 100% owned EL 2014 Makmak tenement on the south coast of New Britain Island, Papua New Guinea. The Makmak tenement is accessible via 4WD vehicle along logging tracks from Kimbe, the Provincial Capital of West New Britain, on the north coast of the island (refer to Figure 1).
A small exploration team collected 32 rock samples, 2 stream sediment samples and 290 soil samples (refer to Figure 2). Of the 26 rock samples measured in the field by Niton XRF*, 15 contained copper and/or molybdenum mineralisation with nine showing values greater than 1% copper at the Pulding prospect (refer to Table 1). Laboratory assay results are expected in November.
Rock float sample number 5021 contained black tourmaline with visible copper mineralisation (chalcopyrite, malachite and azurite) with Niton XRF* measurements averaging 33.5% copper (refer to Photo1).
*Niton XRF measurements are averaged pinpoint readings taken from a number of locations on the surface of each rock sample. These results are considered preliminary estimates only, requiring further confirmation of assay values from an accredited laboratory.
Analysis of the rock samples and airborne geophysics shows a large aerial extent of magnetite and magnetic anomalies. Samples collected from nearby creeks in the “Interpreted Gold Zone” (refer to Figure 2) show abundant magnetite float and panning the sediments has shown an unquantified presence of gold with up to four pinhead-sized nuggets as well as gold dust (refer to Photo2).
Some of the rock samples containing copper and/or molybdenum mineralisation are from brecciated felsic intrusive rocks with associated tourmaline veining and albite alteration (refer to Table 1).
Widespread development of hematite breccia and alteration indicates potential for IOCG (Iron Oxide Copper-Gold) style mineralisation, typical of copper deposits in the IOCG belt of coastal Chile. The magnetic anomalies near the Pulding prospect are sourced by magnetite bearing diorite to quartz diorite intrusives.
