Report Description

Regional geophysical surveys were flown in 2007 and 2008 as part of the QUEST and QUEST-West projects to improve geological understanding in Quaternary sediment-covered areas and thereby encourage mineral exploration. As part of the ongoing process of adding value to Geoscience BC datasets, Project 2009-001, "Integrated Geological & Geophysical Porphyry Models: Adding Value to Geoscience BC Geophysical Data (NTS 93E, 93K, 93L, 93M, 93N)" was undertaken to define relationships between geophysical datasets collected as part of these QUEST surveys and porphyry deposit geology at six known porphyry deposits. The deposits chosen for investigation include: Mount Milligan, Endako, Huckleberry, Bell, Granisle and Morrison.

Geoscience BC Report 2013-14 presents physical rock property data from the six above-listed BC porphyry deposits, and discusses observed trends within the detailed QUEST and QUEST-West geophysical datasets and mapped geology. The resulting physical rock property data compilation has implications for improving interpretations of geophysical data from porphyry deposits. A synopsis of physical property criteria defining hydrothermally altered or mineralized rocks in BC porphyry settings is provided, which can ultimately be used for ranking similar mineral exploration targets throughout BC, thereby minimizing exploration risk.
