Papuan Precious Metals Corp. (TSXV:PAU) reported that further analysis is required from Hole KUD007 drilled at the Kuliuta gold-copper prospect.
The press release is quoted as saying:
Elemental copper is malleable and may smear on and adhere to rock crushing and grinding/pulverising surfaces during laboratory preparation of samples, resulting in either under-estimation or over-estimation of copper grades, or cross sample contamination, or both. Analysis for native copper in drill samples forwarded to the lab has proved to be difficult, as initial results received from the analysis of core from the native copper zone in Hole KUD007 did not correlate with visual estimates. This finding has demonstrated the need for further analysis to ensure assays are accurate with a high degree of confidence, before dissemination of the final results.
