Reports describe the ongoing field prospecting and downstream jade marketing activities associated with the Cowell nephrite jade discovery. Black nephrite blocky material extracted from the operating company's new mining leases (MLs 4130-4132) was...

Exploration of an area located approximately 10 miles north of Manna Hill, seeking possible economic Zambian Copperbelt style stratabound copper deposits, has consisted only of an orientation geochemical survey followed by field inspection of...

A sample of talc from near Weekeroo Station was submitted to the Mines Department (P.356/54) for mineralogical examination on behalf of Mrs M. Talbot, in December, 1954. The sample was found to be a high grade talc, and the deposit was later visited...

An inspection of an occurrence of talc situated in Section 228, Hundred of Jellicoe, 3¼ miles northeast of Truro, was made on 12/10/1960. The deposit was first noted by D. King (Mining Review 103, 1957, pp. 68-69) when a borehole showed about 4 feet...

Talc generally is mined selectively with resultant wastage of reserves due to the discarding of low grade material. In addition selective mining tends to disregard small pockets of high grade material and overall mining costs are high. An...

At the request of the South Australian Department of Mines a survey of current Australian usage of mineral fillers and pigments was made. The survey was intended to determine the consumptions and specifications typical of various industries and to...

A serious breach of Section 17 of the Mines and Works Inspection Act 1920-1962, i.e. the employment of an under-age male person in underground working, was the subject of a complaint which was later verified at the Gumeracha Talc Mine owned by John...

Talc is a hydrated silicate of magnesium having the theoretical formula H2Mg3 (SiO3)4, corresponding to 63.5 per cent SiO2, 31.7 per cent MgO. The ratios of these constituents may vary between rather wide limits, the magnesia/silica ratio ranging...

All the talc deposits investigated occur in schistose dolomite in the Sturtian Series, near the upper or lower limits of a massive interglacial dolomite horizon. Reserves in sight are limited, and further underground exploration of the Nos 4 and 5...

Notwithstanding the increase in the number of open cut workings at the Flinders talc mines, of John Dunstan and Son (W.A) Ltd., the mining of first-grade talc became so restricted that underground mining appeared to be necessary. Recommendations are...

Large deposits of talc/albite rock are known at Gumeracha, about 30 kilometres from Adelaide. The deposits have been worked for low grade talc. Albite feldspar impurity precludes use of the material for many purposes. Since feldspar is a commonly used...

Deposits in the Mount Lofty Ranges are subdivided into the Gumeracha-Lobethal region and deposits north of Gumeracha which include the Lyndoch deposits. On Eyre Peninsula, deposits are concentrated near Tumby Bay, with smaller deposits associated with...

The talc, 14 km NW of Tumby Bay, has been mined intermittently for 40 years. The talc lodes formed in alteration zone which borders folded Katunga Dolomite of the Early Proterozoic Hutchison Group. The talc is white friable and schistose, in thin...
