Sampling activities for mining are often negatively influenced by the generally poor quality of samples you obtain with traditional drilling techniques. Slow advancement of the drill results in your field specialists wasting their time, and a drill grid that is insufficiently explored. Because of poor engineering data due to bad sample quality, high costs will occur in the long run. Our
