The CMIC-Copper project characterized the numerous detectable components that comprise the footprint around the large Highland Valley Copper (HVC) porphyry system.
The mineralization that comprise the many deposits within the system are within a granitoid batholithic complex in a structurally-complex setting. Research will focus on:
- defining the alteration, geochemical, mineralogical and petrophysical footprint patterns that could provide vectors towards the centre of the system;
- identifying the features of the distal alteration halo and discerning its outermost detectable limit beyond the economic mineralized zones;
- investigating the geophysical signatures of the system and its footprint characteristics through refined analysis and modeling of existing and new geophysical surveys,
- establishing links between observable, analytical and remotely detectable features such as petrophysical characteristics of different alteration types;
- establishing derivative responses of footprint features in the overlying surficial environment, and
- using the above results to produce an integrated multi-parameter footprint model for porphyry copper systems.
MDRU had responsibility for several aspects:
In addition to acquiring baseline geological information, MDRU coordinated new geologically-controlled sampling and data acquisition to ensure a consistent approach to data collection. Robert Lee has the main goal task to integrate the geological, structural, mineralogical, geochemical, geophysical, and physical rock property data for the HVC area – essential for the creation of a constrained 3D geological model which will provide a foundation of other data sets.

Architecture of the Highland Valley Porphyry Copper System Through Time
This PhD Guillaume Lesage at MDRU (paralleled by Kevin Byrne at the UAlberta) developed the understanding of the Highland Valley hydrothermal system and its geological architecture. Project focused on geological mapping and reconstruction of the intrusive system to establish the geological, structural and alteration framework of the host rocks and establish the controls on fluid flow.

An MSc study by Rachel Chouinard assessed the geochemical footprint of buried mineralization utilizing a range of conventional and unconventional geochemical and microbiological techniques and evaluated the responses in the glacial till in conjunction with the ongoing geological and lithogeochemical studies.
