Minlaton Bore intersected 596 feet of Lower Permian (?lowermost Sakmarian) glacigenes and then a lower Middle to Lower Cambrian succession 2459 feet thick consisting in downward sequence of Ramsey Limestone (105 feet), red bed clastics (456 feet), Para Limestone (934 feet), Kulpara Limestone (964 feet). From 3075 feet depth to the bottom at 3261 feet the well is considered to have passed through beds transitional between the Lower Cambrian and the Pound Quartzite. Stansbury Bore intersected 119 feet of Oligocene calcareous sandstone and bryozal limestones equivalent to the lower part of the Port Willunga Beds, before passing into Lower Permian (?lowermost Sakmarian) glacigenes 776 feet thick. At 910 feet the well entered a red-bed sequence of current bedded sandstones and chocolate shales considered to be Upper Proterozic (Marinoan Series). Boring ceased in these beds at 1370 feet.
