| Abstract | The Amaruq gold project is part of the Woodburn Lake group of the Rae Domain, in the western Churchill Province. Exploration for BIF-hosted gold deposits in this region has led to an emerging gold
district, which comprises the Meliadine, Meadowbank and Amaruq deposits. In the Amaruq area, the Woodburn Lake group comprises a 250 m thick Neoarchean volcano-sedimentary sequence intercalated with chert and silicate facies iron formations. The two
main ore zones (i.e. Whale Tail and IVR) exhibit different ore and alterations styles related to distinct geochemical and structural traps. The Whale Tail zone is primarily characterized by stratabound pyrrhotite-arsenopyrite-loellingite-gold
replacement type mineralization in chert and iron formation. The ore zones at IVR consist of gold-bearing quartz-carbonate veins developed at, or near contacts between favourable units or reverse fold fault zones. In both ore zones, the geometry and
style of the ore are controlled by at least the two Paleoproterozoic phases of deformation, and crosscutting relationships between folded sedimentary rocks and quartz-carbonate veins indicate protracted hydrothermal activity. |
| 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. |
