Over-all exploration activities (as reflected by expenditures) in western Canada during 1961 continued to decline from the peak year of 1957, with most of the reduction due to decreased wildcat drilling in Saskatchewan and the Territories, and lower Crown land bonuses in Alberta. Seismic work increased slightly (principally in northeastern British Columbia) for the first time since 1953, and surface mapping declined for the second consecutive year. Alberta continued to lead other provinces by a substantial margin in all phases except surface mapping. The Arctic Islands, which began drilling its first wildcat, showed a sharp increase in exploration.
