Water and sediment samples were collected from 13 creeks/springs which drain the Devono-Mississippian Pelly Mountains volcanic belt that hosts the Wolf and MM volcanogenic massive sulphide (VMS) deposits. Preliminary results indicate that water and sediment sampling may be a viable method of exploration for VMS mineralization in this area. A creek draining the Wolf zinc-lead-silver deposit has elevated levels of lead and zinc in water and sediment samples. A sediment sample from the MM zinc-lead-copper deposit drainage is elevated in silver, copper and lead, but not zinc. A creek draining the Fire (Chzerpnough) prospect has elevated levels of barium, lead and zinc in sediment and cadmium, nickel and zinc in water. Each creek sampled has a distinctive white precipitate, coating the rocks, sediment and vegetation in the creek bed, that is likely composed of aluminium hydroxide or aluminium and calcium sulphate.
