| Abstract | Drillhole logging of the three main Carlin-type prospects of eastern Rackla belt (north-central Yukon) demonstrates the diversity of ore styles and the frequent association of mineralization with
several types of brecciated intervals formed through sedimentary, hydrothermal and/or tectonic processes. This attests to the opportunistic nature of mineralizing fluids that exploit permeable pathways, regardless of their origin. |
| Summary | (Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI) is directed towards providing next generation knowledge and methods to facilitate more effective targeting of
buried mineral deposits. The program aims to enhance the effectiveness of exploration for Canada¿s major mineral systems by resolving foundational geoscience problems that constrain the geological processes responsible for the liberation metals from
their source region, transportation of these ore metals and control their eventual deposition. TGI supports projects on gold, Ni-Cr-PGE, porphyry-style mineralization, uranium and volcanic- and sedimentary-hosted base metal mineralization ore
systems, with each project divided into subprojects focused on resolving specific knowledge gaps by integrating data and studies from multiple sites across Canada. Herein, we present interim results and interpretations from a selection of the
research activities currently being conducted under the auspices of TGI. |
