Mass balance preliminary results

MONTREAL, Dec. 15, 2011 - PRO-OR (TSXV: POI). Pro-Or ("the Company") is pleased to announce the results for the phase one of the mass balance project which were recently received from the CIR Laboratory in Quebec. Following are the recovery rates achieved during operation of Pro-Or's pilot plant, which measured for each element of the PGM group (Platinum, Palladium and Rhodium) processed at the facility:

Platinum  greater than 95 %
Palladium  greater than 95 %
Rhodium  greater than 70 %

The platinum and palladium recovery rates are excellent and compare well with the laboratory results obtained during development of the technology. The results of rhodium are less than the other elements as expected for the first phase. Similar results were experienced during the laboratory development of the technology. Through analyzing these initial results, Pro-Or's technical team will propose adjustments and control set points to improve the recovery performance in the next phase, which commenced. The focus will be on an additional treatment to recover the maximum of rhodium still present in the chemical solution. The rhodium is well known to be a stable chemical element reacting poorly with other chemical elements. The Company and its scientific team firmly believe that significant improvements in rhodium recoveries will result from the proposed technical modifications.

At the end of the second phase, results will be reviewed again and final changes will be implemented to maximize total recoveries achievable with the current facility equipment. Mr. Andre L'Heureux, P. Eng., technical director of the project, confirmed that the results obtained and the methodology used are consistent with the results calculated by the CIR Laboratory and is very satisfied with these results.

Pro-Or president, Sylvain Boulanger, states "we are increasingly pleased with the improvements being made to our patented PGM recovery progress and we are aggressively perusing strategic business alliances with suppliers of catalytic converters. These alliances will secure fixed pricing for catalytic converters, in order to generate accurate financial forecasts for the company and its shareholders."

About CIR Laboratory:

CIR Laboratory is a private corporation that offers efficient and cost effective quality control solutions for the refractory, carbon and metallurgical industries, including post-mortem analyses and simulation tests.

Its team of experts also offers turnkey R&D solutions to problems related to the elaboration and the use of industrial materials at high temperatures in order to optimize the most demanding processes.

With ample experience in both the industrial (principal scientist at Alcan International-CRDA) and academic field (teaching master and chair holder of the NSERC chair known as REFRAL), Dr. Claude Allaire oversaw the Pro-Or sampling and results on behalf of CIR Laboratory. Dr. Allaire heads a team that has recently contributed to some successful R&D achievements, such as:

  • The development of a new process for clay decarbonation;
  • The strength maximization of a no-cement backfill paste for the mining industry;
  • The development of a new aluminum non-wetting additive for high temperature applications;
  • The development of a castable new silicon carbide-graphite.

About the Pro-Or technology

Founded in 1986, Pro-Or has become a pioneer in technology and possesses two unique patents developed since 2000 in collaboration with the INRS.(National Institute of Scientific Research post-doctorate). R&D investments totalled close to $20 million over 10 years of development through to patent. The process recovers PGMs from ore and rich concentrates of PGMs, mainly from the recycling of used automobile catalytic converters. The process is environmentally friendly and requires a small amount of energy relative to current conventional smelting processes used in PGM recovery. Benefits of Pro-Or's process include a much shorter processing time (24 hours), a high recovery rate and a small scalable facility. Pro-Or believes that their patented recovery process has the potential to transform current worldwide PGM industry practices. At today's value, the content of precious metal in a ton of ceramic extracted from catalytic converters can exceed $ 150,000 per ton.

The current spot prices per troy oz. for the precious metals are in the table below:
