Geological investigations, survey work, and mapping were carried out in the vicinity of the Tennant Creek gold field between 1948 and 1950. This report provides an overview of the investigations carried out on the Enterprise, Patties, and Eldorado mines. The working, production history, and geological features of these areas are discussed.

This report is a review of the Yukon mineral industry for 1971 and 1972 by the Northern Economic Development Branch of the Department of Indian Affairs and Northern Development. The information in this report was obtained from property visits, communication with company personnel, technical reports of companies, trade journals and reports of the Mining Recorders of the Dawson, Mayo, Watson Lake and Whitehorse Mining districts.

This report is a review of the Yukon mineral industry for 1978 by the Geology Section, Yukon, Northern Affairs Program, Department of Indian and Northern Affairs. It includes descriptions of work conducted on mineral claims by individuals and mineral exploration companies and operating summaries of the several producing mines in the Yukon. Information in this report was obtained largely from the geological, geochemical and geophysical reports accepted for credit as assessment work by the Department of Indian and Northern Affairs. A list of assessment reports, both confidential and those available for inspection, is included in the list of Technical Reports. In this report, activities of the mineral industry are divided into lode mining and exploration and coal mining and exploration.

A reconnaissance study of the composition of gold from several placer streams in the Stewart River map area was carried out to characterize the likely style(s) of lode mineralization from which the placer gold in each stream was derived. Results of the study indicate that placer gold from Eureka and Black Hills creeks, as well as gold grains from colluvium in exploration pits at the head of Eureka Creek, have relatively low fineness, low copper contents and high mercury contents. These compositions are consistent with both the gold in colluvium and most of the placer gold having been derived from epithermal sources in the Eureka Dome or Henderson Dome area. Gold in placers in the Moosehorn Range is likely derived from intrusion-related, gold-bearing quartz veins exposed in the headwaters of the placer creeks, and is characterized by relatively high fineness, high copper contents and low mercury contents. Placer gold in Thistle, Kirkman and Blueberry creeks is very similar to that from streams in the Moosehorn Range, suggesting that an undiscovered intrusion-related gold deposit is present within the Thistle/Kirkman drainage basin.

This report is a summary of activity by the mineral industry in the Yukon Territory and the southwestern District of Mackenzie during 1969 and 1970, by the Northern Economic Development Branch of the Department of Indian Affairs and Northern Development. The information was obtained from visits to properties, correspondence with company personnel, technical reports of companies, newspapers and trade journals and from the reports of the Mining Recorders of the Dawson, Mayo, Watson Lake and Whitehorse Mining Districts.

This report is a review of the Yukon mineral industry for 1973. The information in this report was obtained from visits to mineral properties and by personal communciation with individuals involved as well as from technical reports, trade journals, newspapers, publications of the Geological Survey of Canada and the monthly reports of the Mining Recorders of the Dawson, Mayo, Watson Lake and Whitehorse Mining Districts.

This report is a review of the Yukon mineral industry for 1974 by the Northern Natural Resources and Environment Branch, Department of Indian and Northern Affairs. The information in this report was obtained from visits to mineral properties and by personal communciation with individuals involved as well as from technical reports, trade journals, newspapers, publications of the Geological Survey of Canada and the monthly reports of the Mining Recorders of the Dawson, Mayo, Watson Lake and Whitehorse Mining Districts.

A reconnaissance-level study of post-mining hydrogeochemical conditions was carried out at the Brewery Creek gold deposit within the Tintina Gold Province. The deposit is characterized byepizonal mineralization with a consistent arsenic-gold-mercury-antimony geochemical signature. Surface discharges and seeps in the area are naturally alkaline (pH=7.6-8.2), Ca-HCO3 ¯-SO4²¯ waters. Upstream from the recognized mineralization, waters contain <3 ¿g/L As and <1 ¿g/L Sb. Water samples immediately downstream from the ore bodies show maximum concentrations of 18 ¿g/L dissolved and 47 ¿g/L total arsenic, and 18 ¿g/L dissolved and 21 ¿g/L total antimony. Two kilometres below the mineralization, on lower Laura Creek, arsenic concentrations are diluted to background levels of <3 ¿g/L, and antimony levels are still slightly elevated at 9-10 ¿g/L. Comparison with hydrogeochemical data from Donlin Creek, an undeveloped epizonal deposit in Alaska, indicates that elevated concentrations of a few tens of ¿g/L arsenic and antimony are typical of waters draining such gold systems, regardless of their state of development. In addition to their usefulness for the construction of geoenvironmental models, these data also provide information for establishing exploration programs utilizing water sampling.

URL: https://geoscience.data.qld.gov.au/dataset/cr123356 Exploration Permit for Minerals EPM 16201, Kuridala North, was obtained to explore for iron oxide-coppergold mineralisation, copper-gold mineralisation, massive sulphide lead-zinc-silver deposits, molybdenum and uranium mineralisation hosted either within granites or within sandstone or limestone rock-types. Work conducted over EPM 16201 during the life of tenure has included, several phases of target generation, detailed airborne magnetic surveying, stream sediment sampling, rock chip sampling and soil sampling. No on ground exploration activities were completed within EPM 16201 during the current reporting period. Targets have not met Chinova’s thresholds for continued exploration and the licence was allowed to expire on its anniversary date.
