The applicant proposes during the two year SML period to undertake a work and study programme to determine the economic feasibility of developing a seawater salt recovery complex on the areas applied for, which will be capable upon completion of the initial stage of development of producing one million tons of washed salt per annum. Further studies will be undertaken to determine whether the complex is capable of development to produce three million tons of salt per annum. If the feasibility studies indicate that the project is viable and economic, it is proposed to set up solar evaporating areas at both Point Paterson and Port Pirie. The programme envisages pumping high density brine from the Port Pirie area to the Point Paterson area into already established crystalliser ponds, where the salt would be precipitated during the summer months of September through April and harvested during the winter months of May through August. During the initial investigation of northern Spencer Gulf coastal sites that might be suitable for the large-scale solar evaporative production of seawater salt, the subject reports were written for the project proponents and tendered, as supporting data, in their application to be granted a two-year special mining lease for the purpose of conducting work and studies on the economic feasibility of the planned salt production complex. Presents lithological logs of test bores 1 to 56 plus results of civil engineering mechanical tests done on the recovered coastal plain soil samples. This work was done as part of Government assistance to a project designed to scale up the salt recovery operations at Point Paterson to make them more economically viable, principally through the construction of new seawater evaporation pans that would allow less brine loss to seepage, besides repairing and strengthening the embankments and levees of the old installation.
