The people that use sodium cyanide want to optimize their gold recovery. To avoid a drop in recovery levels, they often prefer to err on the high side of concentrations and use more cyanide than necessary. Our proprietary Cyanide Control System technology allows companies to remove this variation and be more precise and effective when it comes to recovery levels. There is a sweet spot when it comes to the use of sodium cyanide, using too much cyanide can cause cyanide solutions to leach unwanted metals and using too little can drop recovery rates. This is where technology and applications can play an important role. Our tools are advantageous because they are easily incorporated into systems that are already fully automated.
If a new method of extracting gold without sodium cyanide were to become technically and economically viable, this will of course have an adverse effect on our business as it is today. We have invested substantial time and resources internally to try and find an alternative to current practices and technology, and mining companies have been making similar efforts as well. So far, all efforts have been unsuccessful, simply because sodium cyanide is a unique product, and I do not anticipate a drastic change in the short term. Several new companies and young engineers are trying innovative methods and we support those efforts entirely and join them when possible. The reality, though, is that new technologies in this industry take a long time to develop. It will be a long-term project, with a lot of trial and error.
