Frac sand is used in the oil and gas industry in fracking, the method used to exploit hydrocarbons, using liquids pumped in to fracture the rocks. It has been particularly widely used in the US oil industry - to exploit shale.
As reported earlier this month, last summer a program of mapping and sampling of the Mount Wilson formation at the 100% owned project was completed to assess its potential for both high-purity silica and frac sand.
Highlights were that 22 of the 60 samples returned greater than 99% SiO2 (silicon dioxide), to a peak of 99.89% silicon dioxide, and the property confirmed its high-purity silica potential.
Today, 92 said that also 11 samples were chosen for possible frac sand determinations.
These were based on various criteria, including at least medium sand grain size, and visual estimates of friability.
After certain lab work, eight samples were considered sufficiently easy to disaggregate to continue testing, and then six samples passed all tests and produced frac sand sized grains with sufficient roundness and sphericity to be considered potentially saleable, said 92 Resources.
The best results were from two samples adjacent to the Mt. Moberly silica mine property with the remainder from the southern one-half of the Frenchman's Ridge deposit, the firm added.
In early 2014, the firm acquired a 100% interest in an initial 807.77 hectares, next to the south boundary of the Mt Moberly mine and over Frenchman's Ridge.
The property has now been expanded six-fold to over 5,000 hectares, to cover favourable ground with quartzite-sandstone exposures.
92 Resources shares stand at C$0.090 in Toronto.
