Cyanidation of tailings from ore crushed at the Government Stamp Battery at Peterborough ceased in 1964. Previously cyanided tailings stockpiled between 1897 and 1964 contain 5 020 tonnes averaging 3.2 g/t gold (total gold content 16 162 grams). No...

From commencement of crushing operations in March 1933 until its closure in March 1954, the South Australian State Government battery at Mongolata Goldfield crushed a total of 7600 tonnes of ore for a recovery of 318.25 kg of gold bullion via onsite...

This report was prepared as a summary of all open file mineral exploration data from the KINGOONYA 1:250000 mapsheet area that are held in the SADME records management Envelope system. The aim of the holdings review was to describe past exploration,...

Rare specs of gold were found at an old ochre mine next to the township of Oodla Wirra in remnant Tertiary and Recent alluvial deposits. Gold has also been recovered from a haematite vein in Adelaidean Umberatana Group rocks. Mining and sampling has...

The Challenger gold deposit lies in the northern Gawler Craton, South Australia, 750 km NW of Adelaide, and 140 km NW of Tarcoola. A 1.5 km traverse (the regolith line) was chosen for the study of geochemical dispersion and regolith stratigraphy...

Significant exploration focussed on: · stratabound 'Telfer-style' gold in Adelaidean metasediments in the Nackara Arc, using stratiform or stratabound structurally-controlled genetic models; and structurally controlled gold and base metal...

A partial leach soil geochemical survey has been conducted over shallowly buried Cambrian Kanmantoo Trough metasediments in the Monarto South area. The survey was designed to cover a aeromagnetic high anomaly, that is interpreted to be related to a...

The Cambro-Ordovician Black Hill Norite inlier protrudes through Tertiary marine sediments of the Murray Basin about 85 km east of Adelaide. Available evidence suggests that the complex may be a layered mafic-ultramafic intrusive suite with potential...

The metamorphic rocks to be examined on the field excursion have been assigned to the Tapanappa Formation (Early Cambrian Kanmantoo Group), a generally monotonous sequence of greywackes with narrow siltstone partings. This formation hosts most...

Generalised contouring of the Mount Lofty Ranges aimed at reconstructing the Tertiary landsurface topography has identified the locations of a number of possible buried fluvial valleys and channels associated with the St Vincent Basin palaeodrainage,...

5 profiles were recorded to define the extent of a subsurface alluvial channel. The western limit is controlled by outcropping Adelaidean bedrock, while to the east interpreted depths of 30-40 metres to bedrock were indicated. To date the eastern...

During the period December 1989 to March 1990, exploratory drilling undertaken by SADME Mineral Resources Branch over the northern part of Kangaroo Island investigated the potential for base and precious metal mineralisation within rocks of the...

This report summarizes information on 10 South Australian mineral deposits with individual aggregate gold resources and/or historic production of 1 tonne or more. By far the largest is the Olympic Dam Cu-U-Au-Ag deposit, with a measured and indicated...

The Lady Jane Gold Mine, located 8 km NE of Callington, consists of an arsenic and gold rich quartz vein lode, within the Cambrian Tapanappa Formation. Arsenopyrite was reported to be the principal ore mineral, with supergene copper in places. The...

Company exploration within the CURNAMONA 1:250 000 sheet area was reviewed by the study of data incorporated in the open file reports on 42 Special Mining Leases, 80 Exploration Licences and one group of Mining Leases dating from 1961. This data...

An appraisal of Mineral Claim 2597 at the Golden Slope workings on the Mount Grainger Goldfield has revealed gold mineralization associated with hydrothermally altered basal arkosic sandstone of Appila Tillite and the underlying Burra Group shale. A...

The Mannahill area has been prospected and mined since 1881, with ore being treated at numerous locations and by several processes. Gold occurs sporadically in quartz veining over 70 square km. The maximum depth of any working is < 80 metres on the...
