ZINC-LEAD DEVELOPMENT: Halfmile mine nearing production

NEW BRUNSWICK - Vancouver's Trevali Mining Corp. continues to develop its Halfmile zinc-lead-silver-copper-gold deposit near Bathurst for production by the end of the year. Only 120 metres of ramp development remains until the Upper zone is intersected.

A construction workforce of 75 people is on site, and when mining begins the company anticipates providing 80 full time jobs. A Mi'gmag benefits manager has been appointed to oversee the impact benefits agreement between Trevali and the local First Nations. Tests have revealed that mine waste rock is non-acid generating. The water treatment plant contract has been awarded, and the effluent plant is under construction. The infrastructure - dry, shops, office, power, water system and lined mill feed storage pad -  are done. The main mechanical shop is not completed yet.

The ore is to be processed at Xstrata Zinc's nearby No. 12 mill. Metallurgical tests indicate that the Halfmile polymetallic mineralization will yield high-quality concentrates.
