URAGOLD RAW QUARTZ ASSAYS AS HIGH AS 4N PURITY (99.99% SIO2) PRIOR TO COMMENCEMENT OF TESTING
Pretesting analysis of Uragold Bay Resources Inc.'s raw quartz material has yielded purity levels as high as 4N (99.99 per cent) SiO2
(silica).
Bernard Tourillon, chairman and chief executive officer Of Uragold, stated,
"Using these new results, theoretical modelling of PyroGenesis's
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 per cent)
is within reach, and, with anticipated process improvements, further testing could achieve purity of 5N
(99.999 per cent)
and even further to 6N
(99.9999 per cent)."
The raw quartz material was taken from Uragold's 100-per-cent-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 was required for theoretical modelling purposes of
PyroGenesis's
Purevap QVR
process.
Martinville raw quartz results indicate that, even before any benefaction, the material meets industry standards
for ultrahigh-purity quartz.
Ultrahigh-purity quartz has become one of today's key strategic minerals, with applications in pharmaceutical and high-technology industries, semiconductors, telecommunication, optics, microelectronics, and solar applications.
The price of ultrahigh-purity quartz can range from $300 (U.S.) per tonne SiO2
of 99.95-per-cent or 3N-plus purity to over $5,000 (U.S.) per tonne SiO2 of
99.997-per-cent or 4N-plus purity
due to the importance of this mineral to almost every industry in the world.
Mr. Tourillon further stated:
"Reaching 4N (99.99-plus-per-cent) SiO2
purity without any benefaction is outstanding and confirms the exceptional quality of the Martinville quartz. The ultrahigh purity of our raw quartz will allow Uragold to develop both its solar grade silicon business and its ultrahigh-purity quartz business, therefore reducing its technology risk while increasing its potential revenue streams."
Total impurities count less than 100 parts per million measured in Martinville raw quartz assay results
The
analytical data measured in the INRS-ETE laboratory confirm the presence of very pure silica with very low total concentration in all the major contaminants, around the 100-part-per-million threshold, for the Martinville property. Total contaminant concentration was calculated by summing the following elements: titanium, iron, manganese, magnesium, calcium, sodium, potassium, phosphorus, chromium, barium, strontium and copper.
The Martinville property
The total exploration area of the Martinville deposit is 2.42 square kilometres. The deposit consists of hydrothermal quartz veins encased in schists.
In 1995, a geophysical survey resulted in an exploration potential estimated at over one million tonnes of SiO2
using the 200-metre surface length of the quartz vein, with an average width of between two metres and 23 metres and assuming a continuation up to 30 metres 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 NI 43-101 reporting standards. The historical estimate should not be relied upon until the company can confirm them.
Testing methodology:
In order to have a good sampling spread, seven 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. Seven prepared samples were retested for major and trace elements by multiacid (hydrofluoric acid, nitric acid, hydrochloric acid and perchloric acid) total digestion, ICP/OES (26 elements). The assay was performed using atomic emission spectroscopy (Varian, axial Vista).
