The 17-003B Silica Property is located along the west side of Pine River, 45 kilometres southwest of Fort St. John and 30 kilometres northeast of Chetwynd, B.C. The property covers a greater than 10 kilometre long northeast trend of silica deposit potential.

The property contains significant inactive dune formations. The geological conditions and weathering process that created these dunes provided natural mechanical sorting and rounding of silica grains, offering potential for a viable granular silica deposit for use as proppant. Prospecting and geological surveys determined that a silica deposit is present, while targeted drilling helped delineate the total extent of this deposit and provided more detailed lithologic data. An analysis of silica content, grain size, sphericity, and roundness determined that the silica is potentially viable for use as hydraulic fracture proppant.

Hicken et al. (2010) completed a preliminary assessment of silica sources in northeast British Columbia to determine their potential as hydraulic fracture proppant. Silica sources within the property are from the Lower Pine River dune field. Well-developed parabolic dunes in the property area are likely derived from sandy glaciofluvial and glacial till sediments associated with the Cordilleran Ice Sheet (Hicken, et al. 2010).

Following a desktop geological review and field scouting in 2018, 543077 Alberta Ltd. identified the property as having potential as a mineral resource. The preliminary evaluation of the geology of the property was enhanced by 0.5 km of line cutting and 14 test holes (Assessment Report 37972).

In 2019 543077 Alberta Ltd. completed prospecting, along with sediment geochemical sampling and geological mapping to evaluate the potential of silica deposits for industrial purposes specifically for use as hydraulic fracture proppant. Twenty-one test holes were completed and 39 samples collected for analyses (Assessment Report 38863). Physical - Chemical Properties of the silica deposits explored on the property to date are as follows:

Impurities: Moderate 35-40% (CaO, Al2O3, Fe2O3)

Grain Size: 71% falls within the desired 40/70 and 100 mesh size range

Colour: Light Brown

Roundness: Moderately Rounded: 5 to 9, average 6

Sphericity: Moderate 3 to 6, average 4

Clusters: Few

Fracturing: Moderate

Silica (SiO2) content: Highly Variable, but Low; 71.5 to 89%
