TSX Venture Exchange-listed Adex Mining has contracted Toronto-based Watts, Griffis and McOuat (WGM) to prepare updated mineral resource estimates and NI 43-101 -compliant technical reports for the Fire Tower Zone (FTZ) and the North Zone of the company's Mount Pleasant property, in southwestern New Brunswick, Canada.

The FTZ hosts tungsten and molybdenum mineralisation and the North Zone contains tin and indium.

The firm is hoping the reports will enable it to upgrade the mineral resource estimates for the two zones to the NI 43-101 'indicated' category, as well as help in preparing for feasibility work at Mount Pleasant.

WGM is completing two stand-alone NI 43-101-compliant technical reports on the FTZ and the North Zone, respectively, in order to keep the mineral resource estimates for the two zones separate and to avoid delays in the completion of the reports, Adex said in a statement.

The two reports will incorporate data from the company's ongoing 2008 exploration drilling program.

"The upgrading of the mineral resource estimates for Mount Pleasant represents another important step in Adex's fast-track approach to moving the project towards feasibility, which, in turn, allows us to evaluate our options as they relate to development and the commencement of production", said president and CEO Kabir Ahmed.

Mount Pleasant was built and developed by the then Billiton in the eighties, but was closed and flooded in 1985, after less than three years in operation, as sliding metals prices meant the mine was no longer economic.

Adex bought the project in 1995, and recently began taking steps towards moving the mine back into production. The company expects to bring the tungsten/molybdenum FTZ into production first, but also has high hopes for the tin/indium zone on the property.

The company announced earlier this month that it had commissioned a scoping study on a potential mine at the FTZ.
