Evaluation of drill core from the Tower property, Grand Rapids

Project Information
Principal investigator:
Chris Couëslan
Partnered with:
Akuna Minerals and Rockcliff Copper Corporation
Location:
NTS 63G14
Project Description
Main objectives:
To evaluate the rocks hosting Cu-mineralization at Akuna Minerals’ Tower property, establish any genetic affiliation to the Flin Flon Domain (FFD), Thompson Nickel Belt (TNB), or Pikwitonei Granulite Domain (PGD), and identify possible VMS-related hydrothermal alteration.
Methodology:
The project would entail relogging of select drill core from the Tower Property using geological knowledge from both the TNB and PGD as a framework. Relogging drill core accompanied by sampling for petrographic studies, lithogeochemistry, Sm-Nd, and U-Pb isotope analyses to provide insight into provenance of the host rock, identify possible Ospwagan Group stratigraphy, and identify potential pre-metamorphic, VMS-related hydrothermal alteration.
Benefits:
Identifying the provenance of the host rocks to the mineralization at the Tower property could expand the mineral potential for the TNB or PGD, or expand the known area of the sub-Paleozoic FFD. Identifying VMS-related hydrothermal alteration could provide exploration vectors to additional mineralization.
Plans for fiscal year 2019-2020:
- Collect sample of least-altered rhyolite for U-Pb geochronology
