During last summer, a programme of mapping and sampling of the Mount Wilson formation 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.
Meanwhile, 50 of the 60 samples returned greater than 98% SiO2 and there were low levels of iron contamination.
The company said that the majority of the samples were collected from the easily accessible Frenchman's Ridge deposit, where the Mount Wilson formation has been mapped over a strike length of around 1.2km, more than 400 metres width and is interpreted to be at least 50 metres thick.
"The results of the programme demonstrate the property hosts a mature quartzite characterised by high-quality and high-purity silica, which outcrops over a considerable strike lengths and thicknesses," said 92 Resources.
In addition, the results indicate considerable potential to address the high-purity silica market where silica serves, as an essential ingredient for use is polysilicon and various metallurgical applications, such as solar cells.
Due to the results, 92 said it had strategically expanded its tenure holdings south of Golden by around 1,800 hectares and the new lands cover the nearly 6km km long low-elevation outcrops of the Mount Wilson formation, it said.
The tenures are immediately east and south of the Horse Creek silica lease managed by HiTest Sand Inc, which is reportedly being developed as a silica source for a future refinery in Washington state.
