Uragold Raw Quartz Assays As High As 4N Purity (99.99% SiO2) Prior To Commencement Of Testing
Montreal, Quebec, Canada / TheNewswire / March 3, 2016 - Uragold (TSX Venture: UBR) is pleased to announce that pre-testing analysis of its Raw Quartz material has yielded purity levels as high as 4N (99.99%) SiO2.
Bernard Tourillon, Chairman and CEO Of Uragold Stated: “Using these new results, Theoretical modeling of PyroGenesis PUREVAP™ Quartz Vaporization Reactor (QVR) process seem to indicate that transforming Raw Quartz into High Purity Silicon metals with a minimum purity of 4N (99.99 %) is within reach and with anticipated process improvements further testing could achieve purity of 5N (99.999 %) and even further to 6N (99.9999 %)”.
The Raw Quartz material was taken from Uragold’s 100% Owned Martinville property, located in the Eastern Townships region of Quebec. The analysis completed at the INRS - ETE (Institut National de la Recherche Scientifique, Eau Terre Environnement) laboratory in Quebec City were required for theoretical modeling purposes of PyroGenesis PUREVAP™ QVR process.
Martinville Raw Quartz Results Indicate That Even Before Any Benefaction The Material Meets Industry Standards For Ultra High Purity Quartz.
Ultra High Purity Quartz has become one of today’s key strategic minerals with applications in pharmaceutical and high-tech industries, semiconductors, telecommunication, optics, microelectronics, and solar applications.
The price of Ultra High Purity Quartz can range from $US 300 (SiO2 99.95 % or 3N + Purity) -
> $US 5,000 per ton (SiO2 99.997 % or 4N + Purity)1 due to the importance of this mineral to almost every industry in the world.
Bernard Tourillon Further Stated “Reaching 4N (99.99 +%) SiO2 Purity without any benefaction is outstanding and confirms the exceptional quality of the Martinville Quartz. The Ultra High Purity of our raw quartz will allow Uragold to develop both its Solar Grade Si business and its Ultra High Purity Quartz business, therefore reducing its technology risk while increasing its potential revenues steams.
Total Impurities Count < 100 Ppm Measured In Martinville Raw Quartz Assay Results
The analytical data measured in the INRS - ETE laboratory confirms the presence of very pure silica (SiO2) with very low total concentration in all the major contaminants, around the 100 ppm threshold, for the Martinville property. Total contaminant concentration (ppm) was calculated by summing the following elements (Ti, Fe, Mn, Mg, Ca, Na, K, P, Cr, Ba, Sr, Cu).
2016 MARTINVILLE TOTAL IMPURITIES GRAPH:
Figure 1: Total concentration of contaminants (ppm) from the Martinville Property silica samples are closely ranged above and below the 4N grade on the right. 4N Purity implies impurities concentration in the material are 100 ppm or less. (INRS Data).

This table represents the analytical data measured by the INRS laboratory.
The Martinville Property:
The total exploration area of the Martinville deposit is 2.42 Km2. The deposit consists of hydrothermal quartz veins encased in schist’s.
In 1995, a geophysical survey resulted in an exploration potential estimated at over 1,000,000 tons of SiO2 using the 200 m surface length of the quartz vein, with an average width of between 2 m and 23 m and assuming a continuation up to 30 M of depth. (GM53696: Pierre Vincent, Constellar Geosciences. 1995.).
All the information on exploration potential herewithin presented is historical in nature and while relevant, the information was obtained before the implementation of National Instrument 43-101 and as such does not meet National Instrument 43-101 reporting standards. The historical estimate should not be relied upon until the Company can confirm them.
In order to have a good sampling spread, 7 samples were taken at different zones of the quartz vein outcrop in 2014. The material was sent to the INRS ETE laboratory in Quebec City to be prepared for testing for Silica values. To avoid metal contamination the samples were cleaned using silicon carbide (abrasive) and subsequently pulverized with an agate mortar and pestle. 7 prepared samples were re-tested for major and trace elements by multi acid (HF, HNO3-HCl-HClO4) total digestion, ICP/OES (26 elements). The assay was performed using Atomic emission spectroscopy (Varian, axial Vista).

Uragold, with its worldwide exclusive usage of PyroGenesis’ PUREVAP™ QVR, is endeavouring to become a vertically integrated High Purity Silicon Metal (99.99% Si), Solar Grade Silicon Metal (6N Purity / 99.9999% Si) and/or Higher (9N Purity / 99.9999999% Si) producer.
The PUREVAP™ QVR process’s big advantage is its one step direct transformation of Quartz into High Purity Silicon Metal (99.99% Si), Solar Grade Silicon Metal (6N Purity / 99.9999% Si) and/or Higher (9N Purity / 99.9999999% Si) producer, thereby potentially allowing Uragold to manufacture high value material for the same operating cost presently being paid by traditional producers to make Metallurgical Grade Si (98.5% Si) using the traditional arc furnace approach.
The science behind PyroGenesis PUREVAP™ QVR process is solid:
••Plasma arc based process can and has transformed High Purity Quartz into Mg Si.
••Plasma arc based process can and is being used to purify Mg Si into higher value materials such as Sg Si.
••Finally, refining Mg Si using an electron-beam furnace in a high vacuum-processing environment has proven the concept of the elimination of elements whose vapor pressures are higher than that of silicon.
What is unique and ground breaking is the combination of these three proven processes into one step.
Uragold is also the largest holder of High Purity Quartz properties in Quebec, with over 3,500 Ha under claims. Despite the abundance of quartz, very few deposits are suitable for high purity applications. High Purity Quartz supplies are tightening, prices are rising, and exponential growth is forecast. Quartz from the Roncevaux property successfully passed rigorous testing protocols of a major silicon metal producer confirming that our material is highly suited for their silicon metal production.
