Gypsum reserves in Snow Lake and Spider Lake within Innes National Park on southern Yorke Peninsula have been delineated by core sampling and auger drilling. Snow Lake contains indicated geological reserves of 2.8 million tonnes of gypsum to an average depth of 0.92 m. Average grade of 76.3% CaSO4.2H2O is well below that of gypsum from Marion Lake. Spider Lake contains indicated geological reserves of 2.4 million tonnes of gypsum to an average depth of 1.18 m. Average grade of 91.6% CaSO4.2H2O is comparable to material obtained from Marion Lake. Seed gypsum crystals were precipitated in Holocene times in a series of evaporite basins formed by topographic lows in the Pleistocene Bridgewater Formation limestones. The lack of a hard floor as exists in Marion Lake will pose problems during mining of Snow Lake and Spider Lake.
