DESCRIPTION OF DEPOSIT
The 777 deposit, located 700 m south of the Callinan mine (See: Mind No. 1045), consists of two lenses, inclined at 41 to 45 , first intersected at 1200 m. The first shallow lens contains copper-rich massive sulphides, the second, deeper lens, contains a zinc-rich mineralization. The shallower copper-rich deposit is near the vent of the exhalative system that is believed to have formed the deposit. Vent feeders are present in the footwall of the copper rich lens, in the form of altered volcanic rocks with biotite, muscovite, talc, chlorite, magnetite, and carbonate. Chalcopyrite and pyrrhotite stringers extend into the copper-rich lens from the footwall. This deposit is very similar in zoning to that of the Flin Flon deposit (See: Mind No. 693), which also had zinc-rich and copper-rich zones (Northern Miner, June 28,1999).

HISTORY OF EXPLORATION AND DEVELOPMENT
Hudson Bay Exploration and Development Company Limited (HBED) discovered the Triple 7 deposit in November 1993. HBED had been exploring in the area production began at the Callinan mine. The initial exploration indicated reserves of 13.4 million tonnes (t) ore grading at 2.5% Cu and 4.4% Zn, 2.7 g/t Au, and 38 g/t Ag, in the two ore bodies. A feasibility study was completed in 1999, (Canadian Mines Handbook, 1998-99) with positive results. The estimate of reserves changed to 14.5 million t ore grading at 2.6% Cu and 4.9% Zn.
Development of a 1540 m shaft began in early 2000, but full production is not expected until 2004. At that point, the mine is expected to produce 1 million t/year and Hudson Bay will have spent $360 million on capital expenditures, including the $135 million expansion of the mill and electrolytic zinc plant (Canadian Mines Handbook, 2000-01).
