Abstract(unpublished)
Foreword
This report describes a research proposal on the Ni-Cu-PGE mineralization potential of the High Arctic Large Igneous Province (HALIP) in the Canadian Arctic Islands. The report focused on a comparison between the lava flows in the Strand Fiord Formation and the Siberian Traps in the Norils'k region, Russia. The report was distributed to several mining companies in 2001 to receive feedback on the scientific objectives, methodology and timelines of the proposed study. Although the project was not initially funded by the Geological Survey of Canada, it led to (1) several B.Sc. Honours thesis projects (Lyon, 2005; Jones, 2006; Hachkowski, 2011); (2) geochronological studies on HALIP rocks (Villeneuve and Williamson, 2006); (3) renewed interest in the interaction between evaporites and igneous rocks (Jones et al., 2007; Zentilli et al., 2008); (4) and a 4-year multidisciplinary project on gossans (Williamson et al., 2014, 2015). The report was an incentive for renewed field investigations on Axel Heiberg Island1 and for an evaluation of the Ni-Cu-PGE potential of HALIP rocks based on geochemical signatures (Ernst and Buchan, 2010; Jowitt et al., 2014). Ultimately, the unpublished report was cited as the driver for an exploration campaign by Vale Inco Ltd. that led to the discovery of a massive sulphide showing in the region of interest (Goddard, 2010). In August 2014, an activity focused on the Ni-Cu-PGE potential of HALIP rocks was approved as part of the GEM 2 research program2 in collaboration with provincial and territorial governments, northerners and their institutions, academia and the private sector (Figure 1). The activity was formulated in response to renewed interest in magmatic sulphide deposits associated with LIPs on a global scale (e.g. Begg et al., 2010; Lightfoot and Evans-Lamswood, 2015; Barnes et al., in press). Publication of this legacy report will provide GEM 2 participants and collaborators with access to research that underpins the current state of knowledge on the Canadian portion of the HALIP. Field and laboratory studies that are underway continue to build upon and refine the interpretations presented here (Dewing, 2015).
Summary(Plain Language Summary, not published)
This publication was originally intended as a scientific research proposal on the Ni-Cu-PGE potential of the High Arctic Large Igneous Province located in Nunavut. The report was sent to several mining companies for feedback on objectives and timelines in 2001. In subsequent years, some of the preliminary interpretations and databases in the unpublished report inspired several research projects as well as mineral exploration activities in the area of interest. This report, now published, will constitute an important resource for GEM 2 participants and collaborators.
