Energy metals firm 92 Resources Corp (CVE:NTY) said it had filed an NI 43-101 report for its Golden Silica property in British Columbia, adding that the property showed both frac sand and silica potential.
Last month, the firm revealed that as well as its high-purity silica, the property had the potential to supply the burgeoning frac sand industry.
In terms of metallurgical silica, the firm said that from a program in 2017, 22 of 60 samples assayed greater than 99% SiO2 (silicon dioxide), including 10 samples, which were greater than 99.4%.
For the frac sand project, six of the 11 high-silica samples indicated the suitability for additional testing based on initial friability testing.
Similar to 2014 results, these samples produced a pure quartz sand from 20 to 100 mesh with sphericity measurements of 0.7 to 0.9 and roundness measurements from 0.4 to 0.6.
In short, based on preliminary results the samples passed certain specifications for frac sand proppant for purity, crush resistance and sphericity.
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.
Metallurgical silica is used in the ever-growing solar panel industry.
Silicon dioxide (SiO2), also known as silica, has many applications, including microelectronics, computer chips and solar panels.
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 more than 5,000 hectares, to cover favourable ground with quartzite-sandstone exposures.
The newly expanded Golden Silica property now brackets or abuts both the operational Moberly Mine that is now producing frac sand, and the Horse Creek metallurgical silica mine, being developed by HiTest Sand Inc.
