A placer mining and exploration compilation of NTS map sheets 115I and 115J/K, southern Yukon Territory, Canada. This compilation includes the location, history and previous work, description of bedrock geology, surficial geology and mineralization, as well as lists of related references. Accompanying the text are two 1:250,000-scale maps (NTS 115I and 115J/K) which display the locations of the placer occurrences discussed in the report.

A placer mining and exploration compilation of parts of the Watson Lake and Whitehorse mining districts, southern Yukon Territory, Canada. This compilation includes the location, history and previous work, description of bedrock geology, surficial geology and mineralization, as well as lists of related references. Accompanying this report are four 1:250,000-scale maps (Watson Lake, 105A; Whitehorse, 105D; Teslin, 105C; and Wolf Lake, 105B) which display the locations of the placer occurrences discussed in the report.

This volume is a compilation of two types of data: placer mining inspection reports and placer exploration assessment reports. Mining inspection reports were compiled from site visits conducted by the Placer Mining Inspection Unit from 1985 to 1988. Assessment report summaries were written from placer assessment reports which were submitted for assessment credit. These placer exploration assessment reports were submitted to the Exploration and Geological Services Division between 1975 and 1988 and contain geological, geochemical or geophysical data which has not been previously published.

This volume follows earlier annual Mineral Industry Reports for Yukon published by the Department of Indian Affairs and Northern Development. In addition to the summaries of work by exploration companies found in those earlier publications, this volume contains reports on the geology of mineral deposits and mineral districts under active investigation by geologists of the Department. This volume further includes a set of maps showing most known mineral occurrences in relation to the mineral and placer claims in good standing with references to descriptions of each occurrence. It is intended to keep these maps up-to-date and to produce them annually as a convenient inventory of occurrences. This volume contains material for two years, effectively bringing this report series up-to-date. The new title for the report was chosen to more accurately reflect its content.
