Pyrogenesis’ Purevap System Exceeds Lab Testing Threshold

PyroGenesis Canada Inc., a company that designs, develops, manufactures and commercializes plasma waste-to-energy systems and plasma torch products, announces today that its client, Uragold Bay Resources Inc. has received the results of samples processed by PyroGenesis’ PUREVAP™ System which reflected purity levels in excess of 99.9%.

The testing involved multiple surface readings which used a Scanning Electron Microscopy (SEM) associated with Energy Dispersive X-ray Spectroscopy (EDX). The analysis confirms production of high purity silicon metal (Si) by PyroGenesis’ PUREVAP™ System during these tests. Of significant interest is that the purity levels of these samples exceeded the testing thresholds of the laboratory detection capabilities and as such, the final purity level has yet to be determined.

Of note, 22 different readings of 100% Si were observed. This can be attributed to the fact that the purity levels of these samples were high enough that they exceeded the impurity detection method utilized by the laboratory.

“These test results reflect the laboratory’s limitation to detect purity levels greater than 99.9%. In such cases, the laboratory records these results as 100%,” said P. Peter Pascali, President and CEO of PyroGenesis. “What we can say with certainty is that we have produced purity levels greater than 99.9%. The samples will now be sent to a specialized laboratory in the United States to be analyzed in parts per billion for the purpose of determining the precise purity levels of the silicon metal produced.”

“We are encouraged by these results as they confirm our expectations of our PUREVAP™ process,” said Pierre Carabin, Director of Engineering of PyroGenesis. “We are looking forward to receiving the additional tests results from the specialized laboratory in the US. In the meantime, we continue to pursue our testing program.”

The project is scheduled to move into the next phase which, if necessary, will focus on improving the purity level of the PUREVAP™.

Bernard Tourillon, Chairman and CEO of Uragold stated, “these test results represent a significant milestone as one of the key goals of our project has been reached – the establishment of a high purity (99.9+%) baseline for the material produced by the reactor. Reaching our goal of transforming Uragold Quartz into Solar Grade Purity Silicon seems even more attainable.”
