Western Australia is poised to have its first uranium mine project, to be operated by Toro Energy.

Australian media received a tip from industry and equity market observers that the state's environment watchdog, the Environment Protection Authority (EPA), has decided to give its full support to plans by Toro Energy to push through with the construction and development of its Wiluna mine in the Mid West region.

EPA had carefully assessed the probable environmental impact of Toro Energy's mine proposal to the immediate community and its environment, including including radiation management, transport, mine closure and rehabilitation, groundwater and water supply, surface water, air quality, flora and vegetation, fauna and habitat and Aboriginal heritage, The Australian reported, quoting Paul Vogel, EPA chairman.

Toro Energy's proposal will become WA's uranium mine project, five years after a ban was lifted that constricted uranium mining in the area. The previous Labor government enforced the ban.

Overall, the proposed mine will become Australia's fifth operating uranium mine.

Toro Energy, controlled 39 per cent owned by OZ Minerals, plans to start the construction and commissioning through 2013. First sales are expected in 2014. It earlier said it hoped to make a final decision on the Wiluna project by end 2012.

Toro Energy forecasts a 1200 tonne a year uranium oxide production from Wiluna. Its projected mine lifespan is up to 14 years.
