The No Fish Vein occurrence is located just south of and along Beale Lake, approximately 77 kilometres northeast of the community of Dease Lake.
The Beale Lake area, bordering the northeast side of the Lower Cretaceous Cassiar Batholith, is largely underlain by the Sylvester Allochthon, a stack of thrust sheets of oceanic to pericratonic arc affinity that overlies the para-autochthonous Cassiar terrane. South of Beale Lake, large parts of the Mississippian to Permian Upper Dorsey assemblage are dominated by green and grey phyllite and quartzite (Precambrian-Devonian Rapid River tectonite).
The No Fish Vein outcrops in a waterfall in a north-draining creek. It is 2 to 8 centimetres wide and strikes west-northwest. The quartz vein contains pyrite, and a grey metallic mineral and is anomalous in copper, silver (1.2 grams per tonne), antimony, tellurium, and cobalt (Fieldwork 2001, page 55).
These vein occurrences (No Fish Vein and Yurso Vein) are on strike with and 2 to 5 kilometres southeast of the Beale Lake vein set (MINFILE 104I 098). They suggest that it may extend through the low-lying country around Beale Lake and, potentially, onto map sheet 104I/15. The granite porphyry dikes that accompany them lend strength to the inferred connection between late plutonic activity and gold mineralization (Fieldwork 2001, page 55).
Work History
In 1983, Canamax Resources Inc. completed a rock, silt and soil sampling program on the area as the Keel 1-3 claims of the Beale Lake property. Two undescribed rock chip samples (3CF-420 and 3CF-421) taken from or adjacent to Keel Creek, approximately 1 kilometre northwest of the No Fish Vein occurrence, yielded 11.20 and 0.23 grams per tonne gold, respectively (Assessment Report 12181).
Two polymetallic veins, the No Fish Vein and Yurso Vein (MINFILE 104I 121) were discovered during 2001 fieldwork by the British Columbia Geological Survey southeast of Beale Lake.
During 2003 through 2006, the area was help by Sutcliffe Resources Ltd. as part of the Beale Lake property. See the Keel (MINFILE 104I 098) occurrence for a complete summary of this work.
