Throughout the 1970s the Australian Design Award-winning Wallis Aircore system was developed. The Wallis Aircore drilling technique has become the standard for drilling by the mineral sands industry. The nickel and uranium boom utilised the Aircore system for drilling in the sticky clays for which the dual tube system has been designed and proven to handle all types of materials. During the 1980s, Wallis Drilling expanded its fleet to include Reverse Circulation, Aircore and Diamond Core drill rigs.
