The area is underlain by the Upper Triassic Stuhini Group, King Salmon Formation which is comprised of a mixed assemblage of sediments, volcanics, volcaniclastics and minor limestone. On the northeast part of the property, the Upper Triassic Sinwa Formation limestone is found along the northeast dipping King Salmon thrust fault. These rocks are intruded by intermediate composition Jurassic and/or Cretaceous plutons which may be part of the Coast Plutonic Complex, and younger porphyritic dykes, possibly Tertiary in age.

Chalcopyrite mineralization occurs within a breccia zone in the King Salmon Formation rocks adjacent to a small quartz diorite stock. This mineralization hosts copper and silver values as described in B.W.M. (104K 011).

Mineralization also occurs within the Upper Triassic Sinwa Forma- tion limestone, in the northwest part of the property, which is comp- prised of thick-bedded, white to grey recrystallized limestone. With- in it are narrow bands of dark grey, carbonaceous limestone and narrow chert beds. Beds of interformational breccia are less than 0.5 metres in thickness.

At or near the quartz diorite intrusive contacts, the Sinwa limestone is partly silicified or altered to a brown weathering dolomite. In places, a weak pale green skarn, containing epidote, diopside, and calcite, with minor disseminated and lesser veinlets of pyrite, have developed. Massive magnetite lenses, up to 25 metres, have developed in the limestone near the intrusive contact. Within the magnetite zones, fine needles of black and rarely white tremolite are common, as well as, blebs of fine crystalline pyrite and trace chalcopyrite. Some zones are totally altered to goethite and hematite. Magnetite stringers are present within the silicified limestone near the King Salmon thrust fault. Trace galena and chalcopyrite are also present in the skarn type rocks.

In 1980, rock samples of the silicified limestone with magnetite carried up to 0.7 grams per tonne gold, as well as, associated arsenic and antimony (Assessment Report 9541).

The property is located between elevations of 4,000 and 4,500 feet on a mountain that rises above the north side of King Salmon Lake. The showing was discovered by Messrs. Bacon and Wolverton while prospecting for the Consolidated Mining and Smelting Company in 1947. Some trenching and sampling was done that summer, but the ground was allowed to lapse. In 1949 the showing was relocated by Bacon and Wolverton.

In June 1950 the Hudson Bay Exploration and Development Co. optioned the property. Some trenching was done and two holes were drilled on the BWM , totalling 287.4 metres. The core recovered showed fewer quartz stringers and less copper mineralization than had been expected and the option was dropped. The assays of several samples taken from the trenches ranged as follows: silver, 0.1-0.4 oz/ton; copper, 0.4 to 0.9 per cent.

The Barb 1-8 claims covering the showings were held in 1971 by Moresby Mines Limited. Work during the year included geological mapping and reconnaissance geochemical sampling.

In 1964, a small airborne and ground magnetometer survey was conducted by Newmont Mining Co. Ltd.

In 1967, the area was examined for porphyry copper potential by Kennco.

Ron Dale of Victoria staked the Barb 1 claims in 1979.

Between 1981 and 1984, the property was optioned to Chevron Standard Ltd. by Ron Dale of Victoria. Geological mapping, soil geochemical and geophysical (magnetometer) programs were undertaken.

In 1988, Westmin Resources collected eight rock on the Barb property, six of which tested areas of anomalous soil geochemistry and skarn related (often magnetite rich) alteration. Soil geochemical sampling of a central 500m by 600m area of the Barb property in 1983 and 1988 demonstrated it to be distinctly anomalous in gold and silver. The anomalous area is open in most directions, especially to the northwest and southeast. Rock geochemical sampling has demonstrated that calc-silicate alteration on the property is often anomalous in gold and arsenic and likely the source of most of the anomalous gold/arsenic soil geochemical values.

In 1989, Cyprus Gold (Canada) Ltd. investigated the area of the Barb claims still owned by Ron Dale. Geological mapping and collection of rock and soil samples was carried out. A total of forty rock samples and sixty-nine soil samples were collected.

In 1991, Omega Gold Corporation collected rock ( 4 7 ) , soil (39) and silt (8) samples on its E claims Rock (47) , soil (39) and silt (8) primarily on the BWM and Barb. The Barb is just off the claims eastern border and some of the BWM may be as well.

In 2004, the property was staked by Clive Aspinall of Atlin. During the summer of 2004 Mr. Aspinall , spent four days sampling the property, and examining rocks. One rock sample was collected for detailed petrological study. During the summer of 2005 Mr. Aspinall spent half a day sampling one of two gossans on the property. Six rock talus samples and one soil were collected for analysis, in addition to one outcrop sample for petrographic work.
