| Abstract | The Targeted Geoscience Initiative 4 is a five-year federal program to provide public geoscience knowledge to improve deep mineral exploration effectiveness. In southern British Columbia, the focus is
on porphyry base- and precious-metal districts.
Preliminary, interjurisdictional activities focused on the sampling of tree bark, as a probe into the subsurface, and 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 of 2011. The determination of complex ice-flow directions from map- to outcrop-scale ice-movement indicators help trace geochemical and
indicator-mineral anomalies back to the original buried deposits.
The studies helped test the sampling media (tree bark and till) as indicators of buried mineralization and thereby help increase the effectiveness of deep mineral
exploration. |
