Seen below is the official testimonial written by the engineer in charge of an EarthZyme and Dust Stop application at one of the largest coal mines in South America. This approval letter was written as a result of the test application described in Cypher's News section exactly one year ago and is proof of the efficacy that EarthZyme can provide in regards to the haul roads used by the massive trucks in the mining industry worldwide. Not long after the EarthZyme application the mine also performed a Dust Stop application to everyone's satisfaction, which you can read about in the official letter supplied by the head engineer of the project below. Both products are of immense value to the mining industry as well as many others and are cost-effective solutions to the problems plaguing these industries today. The unsolicited letter below is absolute verification of the results of this application and to read the details from one year ago please use the following link to direct you to our News article on this website from last year March 15, 2006
