QUEBEC - CENTURY MINING CORP. of Blaine, Washington, has filed an updated NI-43-101 estimate and technical study for its Lamaque underground gold mine near Val d'Or. The new numbers add up to at least 4.5 million oz of contained gold in all categories.
The technical report (filed at www.Sedar.com) includes the following underground resources. Proven reserves are 2.4 million tonnes at 5.26 g/t Au. Probable reserves are 4.5 million tonnes at 4.67 g/t Au. The total measured and indicated resource is 3.7 million tonnes grading 4.27 g/t Au. Inferred resources add up to 17.6 million tonnes at 4.98 g/t Au. There is also a smaller amount of crown pillar material in the West Plug recoverable by open pit methods.
The technical report examines a highly mechanized underground mine that would produce 3,000 t/d of ore. After the Sigma No.2 and No.3 shafts are rehabilitated, a new 2,500-metre production shaftLamaque No.8should be sunk.
The mill will need a general refurbishment and the addition of a gravity circuit. The crushing circuit needs a capacity of at least 5,000 t/d, reducing the material to 10 mm. Consideration will also be given to recovering scheelite, if a saleable product can be made from it.
A comprehensive reclamation plan for the pits, waste dumps and tailings area needs to be prepared.
