This map comprises new mineral map- ping which is the result of processing, interpretation and modeling of level T1 images, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data. Ten ASTER L1T images based on image quality, cloud cover, snow, dark spots and plants coverage have been selected from the downloaded images through NASA's Earth Observing System data. For methodology refer to “Rahimi, M., Angen, J.J. and Hart, C.J.R. (2018). Application of ASTER data to identify potential alteration zones on Micro- wave ridge, northeastern Search project area, west-central British Columbia (part of NTS 093L); in Geoscience BC Summary of Activities 2017: Minerals and Mining, Geo- science BC, Report 2018-1, p. 7–22.” Geoscience BC is an independent, non-profit organization that generates earth science in collaboration with First Nations, local communities, government, academia and the resource sector. Our independent earth science enables informed resource management decisions and attracts investment and jobs. Geoscience BC gratefully acknowl- edges the financial support of the Province of British Columbia. MDRU is a collaborative venture between the mining industry and The University of British Columbia. The unit, which operates on the support and financial assistance provided by the mining industry and the Natural Sciences and Engineering Research Council of Canada, is an internationally recognized research group devoted to solving mineral exploration-related problems. The geological information layer of map is product of the Mineral Deposit Research Unit (MDRU) with contributions by the British Columbia Geological Survey (BCGS). The BCGS is the government agency responsible for providing inventories, assessments, and archives of British Columbia’s geology. It links government, the minerals industry, and communities to geoscience information and mineral resources. To stimulate investment and inform decisions about responsible land and resource management in the province, geoscience data are released through MapPlace, the BCGS online web service.

Product of MDRU - Mineral Deposit Research Unit of The University of British Columbia as part of Geoscience BC’s Search Project. This map comprises new mineral map-ping which is the result of processing, interpretation and modeling of level T1 images, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data. Ten ASTER L1T images based on image quality, cloud cover, snow, dark spots and plants coverage have been selected from the downloaded images through NASA's Earth Observing System data. For methodology refer to “Rahimi, M., Angen, J.J. and Hart, C.J.R. (2018). Application of ASTER data to identify potential alteration zones on Micro-wave ridge, northeastern Search project area, west-central British Columbia (part of NTS 093L); in Geoscience BC Summary of Activities 2017: Minerals and Mining, Geo-science BC, Report 2018-1, p. 7–22.”Geoscience BC is an independent, non-profit organization that generates earth science in collaboration with First Nations, local communities, government, academia and the resource sector. Our independent earth science enables informed resource management decisions and attracts investment and jobs. Geoscience BC gratefully acknowl-edges the financial support of the Province of British Columbia. MDRU is a collaborative venture between the mining industry and The University of British Columbia. The unit, which operates on the support and financial assistance provided by the mining industry and the Natural Sciences and Engineering Research Council of Canada, is an internationally recognized research group devoted to solving mineral exploration-related problems. The geological information layer of map is product of the Mineral Deposit Research Unit (MDRU) with contributions by the British Columbia Geological Survey (BCGS). The BCGS is the government agency responsible for providing inventories, assessments, and archives of British Columbia’s geology. It links government, the minerals industry, and communities to geoscience information and mineral resources. To stimulate investment and inform decisions about responsible land and resource management in the province, geoscience data are released through MapPlace, the BCGS online web service.
