Annual Report, EL 3333, for the Period 18-06-1984-18-06-1985.

Abstract

EL 3333 covers and suurounds reserves of limestone at a prospect known as Elsey Limestone. Both mottled grey-brown crystalline limestone outcrop and more friable porous chalky white limestone are present. Previous workers suggested the former are Tindall Limestone and the latter was Tertiary. The two have quite different chemical compositions that would influence their potential uses for manufacture of cement and/or quicklime. A resource estimate was made previously. During the reporting period, three areas were further evaluated by surface sampling and auger drilling. Assaying was carried out by the Mines Department laboratory. Grades at area one included some material suitable for cement. Area 2 had MgCO3 contents all below 4.5% and CaCO3 over 86%. Area 3 ranged form less than 70% CaCO3 to over 90%, MgCO3 was typically 1.1% but ranging up to over 2%. Further drilling is anticipated.
