Résumé(Sommaire disponible en anglais seulement)
Targeted Geoscience Initiative 4 is a 5-year federal program to provide public geoscience knowledge coverage to improve deep mineral exploration effectiveness. In southern British Columbia, the focus is on porphyry base- and precious metal districts.
The objective is inter-jurisdictional and preliminary activities will focus federal and provincial survey activities in the sampling of tree bark, which provides natural probes into the subsurface, and, of glacial till derived from eroded bedrock and mineral deposits. The first stage comprised pilot studies at the Woodjam district, and Gibraltar and Highland Valley mines in autumn 2011. The determination of complex ice-flow directions from map- to outcrop-scale ice movement indicators help trace till and heavy mineral geochemical anomalies back to the original buried
deposits.
The studies helped test the sampling media (tree bark and till) as indicators of buried mineralization. Pilot studies at the Woodjam district and Gibraltar and Highland Valley mines type areas include 47 till samples and 41 biogeochemical sample sites (66 samples). Results from these samples, expected in mid-2012, will help test and improve these technologies and demonstrate how analysis of the same sediments that hinder surface mineral exploration can help pinpont buried mineral deposits and increase the effectiveness of deep mineral exploration.
