RCTS A Winning Selection For Zortman Landusky Mine Water

Release Date: October 30, 2008

Contact: Rob Thomas

Reno, Nevada - Ionic Water Technologies, Inc. continues to measure success of the RCTS in terms of efficiently delivered non-detect metals levels. Most recently, our team installed the RCTS at Swift Gulch, a watershed impacted by both historic and modern mining operations located at the massive Zortman Landusky Mine in north-central Montana. In our client's words:

Spectrum Engineering evaluated all lime and other possible treatment options prior to selecting the RCTS for trial testing. The leased RCTS-60HS system was installed on September 15, 2008 with the goal of testing the system for 2 months prior to winter shut-down to determine if it would work and whether it should be purchased. The RCTS system worked so well that the decision to purchase was made after only 3 weeks of testing. The lime slurry consisting of Landusky water treatment plant hydrated lime and Swift Gulch water is mixed at about 1 pound per gallon of water. Flows in mid-September have been around 50 to 60 gallons per minute. The upper retention pond has been filling with iron laden precipitates at approximately 0.5 to 1 inch per 24 hours. An Energy Labs 9/23/2008 water sample showed the dissolved iron at 81 mg/L prior to treatment and the iron was at non-detect immediately upon reentry into Swift Gulch. Aluminum was at 6.9 mg/L prior to treatment and was again at a non-detect level after treatment. Cadmium was at 0.0052 mg/L prior to treatment and was 0.0003 mg/L after treatment and settling. Zinc went from 7.84 mg/L to 0.133 mg/L after treatment.

The RCTS system will be tested next at the biological treatment plant during the winter of 2008 and spring of 2009 spring where the Landusky leach pad waters are currently pH adjusted with NaOH and sludge settling is an issue. Assuming positive results on this site problem, a second unit will be purchased to pH treat leach pad waters prior to treatment through the biological process. - William Maehl, Principal & Mining Engineer, Spectrum Engineering
