Equity Identifies “Battery-grade” Silica for Potential Use in Emerging EV Market at the La Ronge Silica Project, Saskatchewan
Equity Metals Corporation (TSX.V: EQTY) (“Equity”) reports analyses and initial test work on its 100% controlled La Ronge Silica Project, an historic sand quarry located in central Saskatchewan, approximately 60 kilometers south-southeast of La Ronge, Saskatchewan and 210 kilometers west of Flin Flon, Manitoba.
Preliminary studies indicate the silica deposit may be developed into a simple and profitable, low-cost mining and washing operation to produce high-purity silica (>98% SiO2), a specialty product. The sand can be mined very efficiently due to its unconsolidated nature. High-purity silica can be converted into silicon, which is being tested by the electric-car industry to replace or augment carbon in battery anodes to dramatically extend the time between charging. Other possible conventional uses exist in the ceramics and glass industries.
The Company acquired the lease as possible fracking sand; however, never mined the deposit. Historic mining was minimal and the extent of the silica deposit is open in all directions and at depth. Equity recognized the purity of the silica and its potential use as a low-cost material to produce silicon for the expected increase in demand due to electrification requirements. In October 2021, Equity initiated a sampling program to evaluate the deposit. Ten representative sites were sampled within the quarry, and sufficient material was collected to derive an average purity of the sand – see location of samples on the attached plan map of the quarry.
The samples were first analyzed by whole-rock analysis for SiO2, Al2O3, LOI (loss-on-ignition, organic material) and other elements. Average results of the 10 samples indicated 96.2% SiO2 and over 2% Al2O3. Assuming that much of the Al2O3 was in the form of clay and that LOI represented organics, a process was developed to wash all 10 samples in the lab and then to re-analyze the residual sample by whole-rock analysis. The result produced an average of 98.1% SiO2, with a range of 96.1 – 99.2%, and with 0.98% Al2O3 and less than 0.1% LOI. The washing process lost a relatively minor percentage of the original samples, approximately 12% of the total sample (2% clay + LOI and 10% SiO2 lost). X-ray diffraction (XRD) has determined that 100% of the material identified by XRD is quartz.
President Joe Kizis commented, “Our Silver Queen precious/base-metal property in BC will remain Equity’s main focus; however, these results from the La Ronge Silica property are very encouraging and suggest it may become a “third leg” value to Equity, in addition to Silver Queen and the diamond properties.
The Electric Vehicle industry recognizes the need to reduce frequency of battery charging in order to be widely accepted by the general public, and much progress on that front has been reported recently by adding silicon. High-purity silica is the feedstock to produce silicon, and now that we have this positive test work, we can investigate potential markets and partnerships for this specialty silica product.”

Samples were submitted to SRC Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan. A 100-gram portion of each sample was subjected to a Lithium Metaborate Fusion process and then analyzed for 16 metallic elements and LOI by ICP Whole Rock analytic techniques. 10 metal results were converted to weight percent of the original sample and then calculated to specific and probable mineral form. The remaining 6 metals are expressed as ppm content of the original sample. On receipt of these initial results, a 100-gram portion of each sample was subjected to a wash and screen process. The +63-micron fraction was re-analyzed by ICP Whole Rock analysis for the same 16 metals and LOI, with similar conversions and calculations as above. Four samples were selected analyzed for quartz content by X-Ray Diffraction. An aliquot of each sample was ground and irradiated with Cu Kα radiation in a Bruker D4 Endeavor X-ray diffractometer (XRD) operating at 1.6kW power. The raw diffraction data was processed for mineral identification and quantification. Quartz abundance was calculated using whole-pattern fitting algorithms with peak intensities scaled with internally consistent relative intensity.
