Location:
Parts of NTS 63J3, 63J4, 63J5, 63J6, 63J7, 63J10, 63J11, 63J12, 63K1, 63K8
Project Description
Main objectives:
To understand the stratigraphy, tectonic evolution and mineral potential of the eastern Flin Flon domain beneath Phanerozoic cover rocks.
Methodology:
The project involves subsurface mapping from aeromagnetic data combined with re-evaluation of drillcore from select drillholes. Whole-rock geochemical data of drillcore samples collected by the Manitoba Geological Survey and industry will be used to investigate rock type, alteration and tectonic setting. Geochronology (ID-TIMS and LA-ICP-MS) and tracer isotopes (Sm-Nd) is being employed to determine the history and evolution of these rocks.
Benefits:
The southern extension of the Flin Flon belt under Phanerozoic cover is the ‘next frontier’ for VMS exploration in the region. Proper identification of these rocks and the tectonic settings in which they formed provides critical information about their mineral potential. This information can inform exploration strategies, ultimately de-risking projects in this challenging but underexplored area.
Plans for fiscal year 2020–2021:
The focus of work for this project in the current year is to assemble all collected drillcore log, geochemical, and geochronological data from the north half of the study area into one Open File report. The Open File will be accompanied by three preliminary maps from the north half of the study area.
