The Lookout showing is located at 1980 metres elevation near the summit of Green Mountain, 15 kilometres north of Olalla, British Columbia.
The area between Nickel Plate Lake and Keremeos contains a sequence of Carboniferous to Triassic volcanic and sedimentary rocks that have been intruded by granitic Okanagan intrusions. Larger intrusions are composed of granite and granodiorite, while smaller stocks are composed of diorite and gabbro. Numerous sills, dikes and apophyses are associated. Carboniferous to Triassic rocks are assigned to the Shoemaker and Old Tom formations. These rocks form the eastern limb of a large anticlinal fold with fold axes striking roughly north. The Shoemaker consists of cherts, greenstone and minor argillite. The cherts of the Shoemaker Formation are commonly lighter coloured (buff, pink, grey, grey-green) and commonly show a saccharoidal texture. The overlying Upper Triassic Independence Formation consists of interbedded, dark grey to black chert (commonly rusty or red stained), chert breccia, and siliceous greenstone containing disseminated pyrite and pyrrhotite or pyrite and arsenopyrite. The area contains numerous stratabound gold bearing, pyrrhotite, skarn-type mineralization.
A 21 to 31 centimetre wide quartz vein was discovered in close contact with a fine-grained diorite and silicified grey limestone, in the shaft. Quartz stringers and breccia fragments were intersected in a fault, 3.6 metres from the tunnel portal. Native gold, chalcopyrite, arsenopyrite and pyrite were reported found in silicified limestone and in the quartz stringers. The hostrocks were dominantly intensely fractured and faulted argillite.
Samples taken in 1987 from the Keremeos claim on Green Mountain yielded significant copper values. Grab sample 40489 yielded 0.21 per cent copper, 1.03 grams per tonne silver and 0.03 per cent tungsten (Assessment Report 10092). Chip sample 40488, over 1.5 metres, yielded 0.11 per cent copper, 1.03 grams per tonne silver and 0.03 gram per tonne gold (Assessment Report 10092).
Work History
The showing was first reported discovered in 1901. In 1911, the Lookout and Mountain View claims were Crown granted to L. Patten and F. Stone. By 1926, the claims were owned by E. Mills, W.R. Mure, Chas Cotterill and P. Bromley. Development work consisted of a series of opencuts and a shaft over 12 vertical metres and 61 metres along strike. In 1931, a 33-metre tunnel was driven, 13 metres below the shaft collar.
The Kero claims (later covered by the Laredo group) were staked in 1964 by M. Schram of Olalla and some trenching on the vein structure was done. In 1972, the property was explored by Lantern Oil and Gas Co. Ltd. as the Karen 1-16 claims. In 1983, Grand National Resources Inc. became the owner of the Kero-Laredo-Puma claims and in 1984-85 work completed on a portion of the Puma 3 and 4 claims consisted of VLF-EM and soil surveys and regional geological mapping. In 1987, L. Reichert examined the Keremeos claim on Green Mountain. Grand National continued work on the Laredo-Puma claims in 1989-90 and 1992 which consisted of soil and VLF-EM surveys.
In 2020, Level 14 Ventures Ltd. completed a program of prospecting, geological mapping and geochemical (rock and soil) sampling on the area as the Green Mountain property.
