The Gully occurrence is located on a north- north west facing slope, north of Kisgegas Peak and approximately 1 kilometre east of Kisgegas Lake.
The area is underlain by siltstones and sandstones of the Middle Jurassic to Lower Cretaceous Bowser Lake Group intruded by granodiorite dikes and sills of the Late Cretaceous Bulkley Plutonic Suite. Several granodiorite plugs, also of the Bulkley Plutonic Suite, outcrop within a few hundred metres of the showings.
Fault hosted veins are associated with Late Cretaceous Bulkley Plutonic Suite. tential for locating a drill target even though they were weak in sulphide composition. The veins generally trend northwest-southeast dipping moderately and steeply to the southwest and include the main Gully vein.
Locally, numerous sub-parallel quartz veins generally from 10 centimetres to 1.0 metre wide cut the diorite at its eastern end. These veins are late, planar, and can be traced for well over 100 metres each. A 0.5 to 1.2-metre thick milky quartz vein at the eastern edge of this stock is known as the 'Gully vein'. The vein is mineralized with pyrite, chalcopyrite, galena and tetrahedrite.
In 2009, a sample (441036) of the Gully vein assayed 0.8 gram per tonne gold, 97 grams per tonne silver, 1.3 per cent copper, 1.77 per cent lead and 3.51 per cent zinc over 1.1 metre (Assessment Report 31149). Also at this time, sampling (441052) of veins parallel to the Gully vein on the margin of the dioritic stock yielded up to 1.76 grams per tonne gold and 109 grams per tonne silver, while samples (441056 and 441055) taken from a previously un-sampled quartz vein at the margin of a dike, located approximately 200 metres to the north east, yielded 0.75 and 0.21 gram per tonne gold with trace and greater than 300 grams per tonne silver, respectively (Thomson, G.R. (2009-10-15): Technical Report on the KM Property).
WORK HISTORY
In 1987, Pantan Resources conducted reconnaissance-style mapping, prospecting and sampling over a 5 day period on their Molly 1-4 claims. Twenty-nine grab samples of primarily quartz vein material containing galena, sphalerite, chalcopyrite, and pyrite were collected within a 2.4-kilometer area. Sampling in 1987 revealed the Kisgegas showing.
In 2009, Cavan Ventures held the KM claims which covered the Kisgegas and Icefields (093M 083) showings. Exploration work on the claims consisted of geochemical sampling and geological mapping which tested previously reported and newly discovered areas of anomalous multi-element precious and base metal values. A total of 33 rock samples, 14 stream-sediment, and 4 soil samples were collected. Rock sampling was focused on widespread mineralized (galena, chalcopyrite, pyrite, and sphalerite) quartz and quartz-carbonate veins hosted within Bulkley dikes/sills, Bulkley intrusive stocks/plugs, and Bowser Lake group of sediments and meta-sediments. Highlights of the 2009 exploration silt program included a multi-element gold, copper, lead and arsenic silt anomaly in a stream flowing from the East Glacier area. In addition, a multi-element anomaly was discovered in the northeast cirque area of the property. The Kisgegas showing (093M 126) area was sampled in this year. The Gully Vein was first reported in this year.
In 2010, a field program consisting of continuous rock chip sample trenching (in 56.3 metres), prospecting/rock sampling and geological mapping in the Gully Vein and Gully Vein West areas and detailed mapping of trenches was performed. Fieldwork consisted of the collection of total of 93 rock samples (75 continuous chip, 7 grab from outcrop and 11 float samples) as well as prospecting and mapping trenches in new areas, including the previously unexplored west end of the main valley and the north and south slopes. Geologic prospecting discovered numerous new mineralized showings. In addition, a new type of mineralization was shown to exist in metasomatically-altered intrusive host rock.
In 2011, Cavan Ventures performed a two-week program consisting of the collection of 3 rocks, 28 silt and 40 soil. Hand-trenching of 9 trenches is reported totalling 56.3 metres. Reconnaissance geological mapping was conducted.
