Title: Background to Present Mineral Search in British Solomon Islands and Fiji: ABSTRACT

Author(s): J. C. Grover

Article Type: Meeting abstract

Abstract:

The effects of earlier mining policy have inhibited exploration. In both countries government geological surveys were established amid hopes that geologists might supplant prospecting activity by private enterprise, a view that matured over the years in the face of reality. Long-range ground exploration, with continued support and technical collaboration from London, produced geologic maps. Modest finances demanded a basic philosophy differing from the advice from the private sector, but outstanding results were produced which even better complemented and supported the role of private enterprise in resources development.

In the Solomons, the situation demanded the evolution of a dynamic role for government. Unprecedented support, from many sources, and international collaboration in a series of ventures led to a buildup in fundamental exploration which deployed scientists, engineers, army personnel, research vessels, and ships of the Royal Navy. Nickel and other minerals were found and drilled. Activity culminated in a regional preinvestment airborne geophysical survey with shipborne and ground follow-up teams of competent indigenous staff and bearers, each team led by a scientist, and involving an expenditure in excess of a million dollars. There were successes and shortcomings. Copper and bauxite were the main discoveries. The knowledge was applied later to Fiji where a different approach was needed

Fiji's mapping progress and observations suggested the need for complementary activity by the private sector. Copper mineralization suggesting porphyry-type potential was described in an official letter to more than 80 major mining companies of the world and was supported by press advertisements. The mining companies were not interested. Three replies were received in 11 months. The government decision led to the discovery of anomalies and large deposits now being test drilled. Other mineral occurrences are also mentioned.

The remaining 5,000 sq mi of the main Fiji Islands was the subject of a decision in the same year. Within well-informed mining policy guidelines, agreement was reached with a highly skilled research group for the expenditure of $2,000,000. The methods and the outcome are described.

Hopes of financial independence now are held where there had been none. The need for a well-informed governmental role in resources development is emphasized as a means to national self realization. Mention also is made of the adjoining New Hebrides and the unusual petroleum potential of the Kingdom of Tonga.
