Capsule Geology

The Misty Mountain occurrences are located in the northern head waters of Buck Creek.

The regional geology consists of two thick volcanic and sedimentary cycles. The first is the Triassic Vancouver Group, consisting of the Karmutsen volcanics, Parson Bay and Quatsino limestones. The second is the Lower Jurassic Bonanza Group volcanics. These packages are intruded by the Middle Jurassic Island Intrusive Suite. Prominent northeast trending faults transect the area.

In 1995, Buck Creek Resources completed a program of prospecting, geological mapping and geochemical sampling. This program identified three mineralized zones over an area of approximately 250 by 250 metres:

1.) The Creek Zone consists of a semi- massive sulphide mineralization associated with a limestone skarn between two subparallel andesitic dikes, striking 045 degrees and dipping 90 degrees. The zone between the dikes ranges from 0.6 to 1.0 metre and the dikes range in thickness from 0.30 to 0.60 metre. The zone is exposed over a 5.0 metre horizontal section. Mineralization consists of massive and disseminated pyrite and pyrrhotite within the limestone skarn between the two dikes and in the limestone at both outside contacts. Minor chalcopyrite was also noted.

2.) The C3 Zone consists of a 2 metre wide fault zone, striking 070 degrees and dipping 070 degrees north, hosts semi-massive sulphide mineralization. Vein or fracture structures appear to splay from the hanging wall of the fault zone. These vein structures range in width to 0.50 metre and are composed predominantly of shattered volcanics with stringers of pyrite and minor chalcopyrite concentrated near the contacts. Mineralization consists of pyrite plus chalcopyrite in discontinuous pods, to 0.20 metre, and stringers, 2 to 15 centimetres, within the structures. In 1995, a grab sample returned 1385 parts per million copper (Assessment Report 24534).

3.) The C3 East Zone consists of a sulphide vein or fracture zone, striking 044 and dipping 80 degrees northwest, splaying from the footwall of the C3 fault. The zone is hosted in the limestone. The width of the zone is 0.2 to 0.1 metre. The vein carries 2 to 10 per cent pyrite and pyrrhotite, along with traces of chalcopyrite and malachite. There are also abundant sulphide vugs. Alteration minerals include chlorite and sericite. In 1995, a lone grab sample returned 1430 parts per million copper (Assessment Report 24534).
