My father and brother who founded this great company in 1965 always said, we’re not drilling a hole in the ground, we’re drilling for a quality uncontaminated sample. Today we continue to judge our success on providing optimal and safe outcomes for clients, not how many metres we drill or how many blast holes we complete in one day.
