QUEBEC – Toronto-based BREAKWATER RESOURCES declares that commercial production was reached on July 1, 2007, at its reopened Langlois copper-zinc mine, 213 km north of Val dOr. The decision to put the property back into production was made in November 2005.

Breakwater made several improvements to the underground workings to control costs and ensure an uninterrupted supply of ore. Chief among these were the elimination of ore passes for Zone 97, a new level 9 ore dump and loading pocket, pre-development of several sublevels in Zone 97 and improvements for the underground mobile equipment fleet. Additionally, the operating plan includes continuing the exploration of Zone 97, which remains open to the east and at depth.

The Langlois deposit contains proven and probable reserves of 3.7 million t grading 10.1% Zn and 0.8% Cu plus gold and silver values. The measured and indicated resources are 5.7 million t grading 10.7% Zn and 0.8% Cu, and the inferred resources are 18 million t grading 8.8% Zn and 0.5% Cu. With metals prices higher now than when the reopening decision was made, lower grade material not previously included may further expand the resources.
