The helicopter-borne VTEM survey will be flown at 100 metre line-spacing and will provide the first property-wide, high-resolution geophysical image of the Property.
The VTEM dataset will help to better define the geological model of the Property and to target conductive portions of the assemblage, both stratigraphic and vertical structural anomalies, particularly those that might be associated with sulphide minerals. The survey will be the first of many modern exploration techniques that will be used to explore and develop the
The Property has yielded significant historical cobalt (Co), copper (Cu) and silver (Ag) results and presents an opportunity to discover battery and electrification metals as the world shifts to electric vehicles, sustainable practices and greener alternatives. The property is hosted within a similar geological setting to the Idaho Cobalt-Copper belt where conductivity (EM) and magnetic surveying techniques have been used previously to successfully guide drilling of prospective targets and assist in making new discoveries.
Grizzly anticipates being able to use data from the survey to gather a better understanding of the geology of the Project and to identify targets for further characterization and investigation later in 2021, leading to a planned summer 2021 drilling campaign.
HIGHLIGHTS FOR THE ROBOCOP PROPERTY
Initial surface trenching in the late 1980's to early 1990's yielded up to 0.06% Co and 1.93% Cu over 6 metres (m) in one trench, and in a separate trench up to 0.146% Co, 1.8% Cu and 5.3 grams per tonne (g/t) Ag over 5 m in sediment-hosted sulphide mineralization within middle
A total of 15 drill holes in the area between 1990 and 2008 have yielded several intersections of near surface Co-Cu-Ag mineralization with grades of up to 0.134% Co, 1.19% Cu and 33.8 g/t Ag over 1.23 m core length in hole R-1990-5 and 0.14% Co, 0.9% Cu and 2.7 g/t Ag over 3.1 m core length in hole R-1990-6 (Thomson, 1990), along with an intersection of 0.18% Co, 0.28% Cu, 4.1 g/t Ag over 1 m core length in hole R-2008-02 (Pighin, 2009).
All but one of the historical drillholes tested a single target in an area about 500 m by 350 m. The Property is approximately 10 km in length and 3.5 km in width and contains at least 4 untested anomalous soil +/- rock geochemical targets.
Sediment hosted Co-Cu-Ag mineralization is similar in style, age and host rocks to mineralization at
The VTEM survey is being conducted to search for and target conductive portions of the assemblage (often spatially related to sulphides including chalcopyrite), as both stratigraphic and vertical structural targets, with the purpose of providing additional targets for future work and drilling to those currently defined by previous drilling along with historical soil and rock sampling.
Prior work has identified areas within the Robocop property with significant historic Co-Cu-Ag in-soil anomalies, combined with historical drilling during the 1990's (
The macroeconomic outlook for battery metals such as Cu and Co remains strong with the ongoing shift to electric vehicles. It is estimated that the battery sector accounts for approximately 57% of current Co demand; this is expected to grow over the next five years to 72% and will require an additional 100,000 tonnes of Cobalt to meet demand.1
