Updating and Revision of the 1:25 000 Scale Series Geological Maps Covering the Mt Read Volcanics Belt in Western and Northwestern Tasmania Mineral Resources Tasmania Tasmanian Geological Survey Tasmania DEPARTMENT of INFRASTRUCTURE, Record 2004/03 ENERGY and RESOURCES Updating and revision of the 1:25 000 scale series geological maps covering the Mt Read Volcanics belt in western and northwestern Tasmania K. D. Corbett Introduction Because the revision of Rcodes involved a statewide database, with flow-on effects to maps outside the This report represents the culmination of a two-stage project area, it was necessary to fully complete the project carried out by the author under the Western revision and updating process for all the project maps Tasmanian Regional Minerals Program (WTRMP) to before the new system could be implemented. The revise and update the series of published 1:25 000 scale revised maps and Rcodes have been presented to geological maps of the Mount Read Volcanics belt Mineral Resources Tasmania, but actual through western and northwestern Tasmania. In implementation of the changes will involve particular, advances in understanding and knowledge of the geology of this belt gained through study of considerable time for re-drafting. WTRMP geophysical surveys (aeromagnetics and (Note added in proof by G. R. Green: The revisions radiometrics) and associated geological mapping, suggested here represent a thorough review and a from recent work by exploration companies in the major advance in the understanding of the geology of area, and from recent University research in the area, the Mount Read Volcanics and adjacent rocks by was to be shown on the maps. Much of this work had Dr Corbett.

RCODE is a unique number given to each rock unit and is used as a link to the geology lookup tables GEOL25.LU or GEOL250.LU or GEOL500.LU and LITH.LU. RCODE is also used to record the rock or mineral type of veins or dykes.

The revised maps were held by the Data preliminary new colour design for the 1:25 000 scale Management Branch, but no revisions were carried out maps, to take account of the geological changes, and pending completion of the northwest and southwest the preparation of this report, in which the major map maps. revisions are listed, and the overall findings of the project in terms of advances in understanding and Stage 2 presentation of West Coast geology are described.

  • Water Management in the Anthony–Pieman Hydropower Scheme
    Water management in the Anthony–Pieman hydropower scheme Pieman Sustainability Review June 2015 FACT SHEET Background The Anthony–Pieman hydropower scheme provides a highly valued and reliable source of electricity. The total water storage of the hydropower scheme is 512 gigalitres and the average annual generation is 2367 gigawatt hours. Construction of the Anthony–Pieman hydropower scheme has resulted in creation of water storages (lakes) and alterations to the natural flow of existing rivers and streams. The Pieman Sustainability Review is a review of operational, social and environmental aspects of the Anthony–Pieman hydropower scheme that are influenced by Hydro Tasmania. This fact sheet elaborates on water management issues presented in the summary report, available at http://www.hydro.com.au/pieman-sustainability-review Water storage levels in the Anthony–Pieman Water levels have been monitored at these storages since hydropower scheme their creation in stages between 1981 and 1991. The Anthony–Pieman hydropower scheme includes eight Headwater storages: Lake Mackintosh and Lake water storages, classified as headwater storages (Lakes Murchison Mackintosh and Murchison), diversion storages (Lakes Lakes Mackintosh and Murchison are the main headwater Henty and Newton and White Spur Pond) and run-of-river storages for the Anthony–Pieman hydropower scheme. storages (Lakes Rosebery, Plimsoll and Pieman). Lakes The water level fluctuates over the entire operating range Murchison, Henty and Newton and White Spur Pond do not from Normal Minimum Operating Level (NMOL) to Full release water directly to a power station; rather they are Supply Level (FSL) (Figures 1, 2). used to transfer water to other storages within the scheme.

AHL are completing a development application (DA) to the West Coast Council for a permit to operate the mine. FIGURE 1 LOCATION Project Description The proposed mining and processing operation is a simple one and similar in operation to a large quarry or other small/medium size iron ore mines in Tasmania. The Tenth Legion magnetite deposit is located approximately 2.5 km NW of the existing Comstock mine and processing plant site. It is a skarn iron ore deposit that is amenable to a small open pit mining, with other nearby deposits also possible for mining in the future. The project will involve two open pits to recover a direct shipping ore (DSO), oxide and fresh iron ore at a mining rate which will recover approximately 3.5 Mt of ore over a five year period producing about 3 Mt of product.
