An indicated 29 100 tonnes of tailings containing 1.88 g/t Au, 2 g/t Ag, 70 ppm Cu, 1200 ppm Pb, 350 ppm Zn, and 80 ppm As in 2 separate dumps remain on site. Cyanidation leach tests show that about 60% of Au in the truck dumps and up to 50% of the Au...

Gold-mineralised rock bulk samples (684.84 tonnes in 25 separate batches) from the Fabian, Ward and Imperial Reefs were selected from 1975 tonnes obtained by trial mining (from April to August 1988), and processed. Two batches from Fabian Reef...

During the Tarcoola Blocks mine trial mining campaign of 1987-88 an exploratory underground diamond drilling program (37 holes totalling 1383.95 m) was carried out from Levels 2 and 3 of the Tarcoola Main Shaft. The targets were possible extensions...

The second phase of exploratory RC drilling in July 1987 involved 42 holes totalling 2656 m, which followed-up the results of the first drilling phase and also sought to disclose other mineralised reef systems within the mining leases.

An investigation of tectonic controls of gold mineralisation in quartz veins at Tarcoola recommended the further study of : - brecciated zones (in which reefs and veins exhibit an increased gold concentration) to establish their structural...

The Tarcoola Joint Venture was formed in December 1986 to explore and redevelop the Tarcoola gold mine. An exploration and mine rehabilitation program included detailed underground surveying, geological mapping, systematic sampling and drilling....

At Tarcoola during 1987-88 a mine exploration and development programme was undertaken by the joint venture companies to assess the economic potential of existing mining leases surrounding the decommissioned Tarcoola Blocks mine. This programme...

Gold mineralisation at the Tarcoola prospect occurs within quartz veins occupying extensional fractures and faults cutting through the quartz sandstone and claystone of the Late Proterozoic Tarcoola Formation. Most of the past gold production has...

The March-April 1987 drilling programme, of 25 angled RC holes totalling 2437 m, tested the gold content of the known mineralised quartz veins and also attempted to determine the distribution of gold within the surrounding Tarcoola Formation....

The third phase of exploratory RC drilling in February-March 1988 involved 71 holes totalling 3090 m, which further investigated unworked extensions to certain reefs and also attempted, without success, to locate the Tarcoola Formation / Hiltaba Suite...

The main focus of a recently begun gold exploration programme on the Tarcoola Goldfield has been the Tarcoola Blocks mine, where gold occurs in subvertical quartz reefs, up to 2 m wide, which cross-cut folded Mid-Proterozoic sandstone and carbonaceous...

Surface geological mapping followed by reconnaissance and detailed exploratory drilling of the Welcome Home lode (40 holes totalling 1945 m) has defined a small resource in the oxidized zone amenable to mining by underground methods. An initial...

This data package is a compilation of recent exploration company data (see Env 6858), and some SADME data, including quartz-vein geochemistry, drillhole analytical data, fluid inclusion data, and a summary of U-Pb and lead isotope analyses. No attempt...
