Tasmania
"The Dove River Tenement was granted in January 2007. The licence is located in the northwest of Tasmania, about 50km south of the port of Devonport and within the Mt Read Volcanic ( MRV ) belt. The MRV in Tasmania hosts numerous mineral deposits and mines which have contributed significantly to the Tasmanian economy, including Rosebery, Que River, Henty, Hellyer, and Mt Lyell.
The Dove River Tenement area has a number of mineral occurrences, old mines, a goldfield, and a number of sites of altered rocks yielding anomalous metal values, but has not been explored in any detail.
Work has more recently shown that the Dove River region shows many characteristics of the copper-gold, high-suphidation, porphyry districts in New South Wales, including the Cadia and Goonumbla deposits. These include the setting and chemistry of the host rocks, as well as the styles of mineralisation and related alteration.
Furthermore, recent mapping and processing of modern geophysics by the Company and government now shows the Dove River region as being located adjacent to a major structural discontinuity. This discontinuity appears to have affected the geology of the area over more than 0.5 billion years. Such structures are ideal conduits for mineralising fluids, with similar structures coinciding with copper-gold mineral deposits elsewhere in western Tasmania as well as in New South Wales.
The changes in the understanding of the Dove River region are such that Mineral Resources Tasmania is now remapping the area. This is the first remapping of the rocks since the late 1950's.
Work performed by the Company to date has identified three main target areas within the Tenement application area: the Devon Mine area, the Powerful Mine area and the Five Mile Rise Goldfield.
Preliminary sampling from around the Devon Mine area has, to date, identified better than expected results for gold, silver and copper, lead and zinc.
Related alteration systems have also been found to be larger than expected, resulting in application for a second surrounding exploration licence ("Lemmonthyme")."
