Pinevale Copper-Silver Project - Detail

Background
Pinevale consists of a small copper-silver ML and a surrounding EPM, is situated in the Mackay hinterland in Central Queensland and encompasses a number of historical polymetallic and precious metal occurrences, the most prominent being the Pinevale occurrence. Details of the project tenements are summarised in the table below.

Location, Access and Topography
The project area is located some 30-45km southwest of the central Queensland coastal town of Mackay and access is via the sealed Peak Downs Highway which transects EPM 13127. The project area topography varies from flat alluvial plains in the northeast to dissected, rugged ranges, rising to about 750m elevation, in the southwest of EPM 13127.

Exploration and Mining History
Total production from Pinevale has been reported as approximately 2,500t averaging 11.5% Cu and 122g/t Ag. Other small producers on the field included Ben Mohr, Bong Bong and Lone Wolf.

Project Area Geology and Mineralisation
The EPM covers the contact between the Early Permian Carmila Beds, a sequence of volcanic-derived sediments and acid to intermediate lavas, and the Carboniferous to Early Cretaceous Urannah Intrusive Complex which, within the EPM, consists of various granitic phases on the eastern side of the project area (Figure 11).

Exploration Programme
Compilation of all available prior exploration data has been completed. During development of the company's database historical reports were located of an early (1950's) ore reserve estimate for the Pinevale Mine, which at the time consisted of an adit and three levels of underground workings. Reports estimated resources of 26,695t of 6.8% Cu, 117g/t Ag and 0.6g/t Au. The validity of these resources have not been confirmed by the company and they do not comply with JORC reporting requirements. Exploration is required to substantiate this mineralisation by drilling and if access is available, underground sampling. Detailed geological mapping, geochemical sampling and geophysical surveys will be undertaken over the known prospects. It is anticipated that this initial work will be followed by drill testing of selected targets. Field work on this project has been delayed pending acquisition of the surrounding 237 sq km EPM and execution of a native title access agreement.
