The DT-010 (Lookout North) occurrence is close to Granby Bay on Observatory Inlet and near the historical mining town of Anyox.
The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive andesite and basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of argillite, siltstone and sandstone with minor chert and limestone. There are two observable phases of folding in the area, an initial north-northeast trending phase followed by a later east-northeast trending phase.
In 2006, Kenrich-Eskay Mining Corp. completed a program of airborne electromagnetic and magnetic surveys, stream sediment and rock sampling, geological mapping and 50 diamond drill holes, totalling 14275 metres, on the area as the Coastal Copper project. Five drill holes were completed on the Lookout North area yielding up to 1.13 per cent copper and 13.4 grams per tonne silver over 1 metre from stinger sulphides intersected in hole LO06-07 (Harrison, D., McKinley, S. (2007-06-18): Technical Report on the Coastal Copper Project, Anyox Area).
Two other holes (LO06-15 and -16), located to the north west on a south east facing slope, encountered a series of quartz-fuchsite bearing veins associated with a contact zone between gabbros and basalt flows yielded values of up to 0.93 per cent copper over 0.51 metre and 0.72 per cent copper over 0.70 metres in hole LO06-15 (Harrison, D., McKinley, S. (2007-06-18): Technical Report on the Coastal Copper Project, Anyox Area).
During 2007 field work by Kenrich-Eskay Mining Corp., a previously unknown historical trench was located (station DT-010). The trench contains chalcopyrite veins hosted in basalt where one grab sample yielded 0.13 per cent copper. The trench is located approximately 360 metres northwest of a chalcopyrite vein that was found in 2006. Three holes were drilled on a nearby AeroTEM conductor in 2006; this drilling yielded several samples anomalous in copper in the upper 50 to 70 metres. A second drill pad was constructed in this area to target a higher intensity AeroTEM anomaly but the hole was not budgeted for completion in 2007. The area continues to be highly prospective (Assessment Report 30152).
