A 2026 report from the Government of Yukon describes enigmatic breccias and mineral occurrences in the Quartet Mountain-Igor area of the Wernecke Mountains. It details widespread metasomatism, metamorphism, and the presence of copper, iron, barium, molybdenum, uranium, cobalt, gold, and silver. The report suggests genetic mechanisms like crustal extension and large buried intrusions.
A paper summarizing preliminary observations from an MSc thesis project on the Minto copper-gold deposit in central Yukon. The research focuses on characterizing mineral textures, chemistry, paragenesis, and structural controls to improve understanding of the mineralized system. It is published by the Government of Yukon and was last updated on 2026-04-17.
Two stratigraphic logs of Mesoproterozoic units PP1 and PP2 in the Coal Creek inlier, Yukon, are presented. PP1 is dominantly siltstone and sandstone, whereas PP2 is mostly dolostone. The data was published by the Government of Yukon and last updated on April 17, 2026.
2764 km of airborne geophysical survey data was collected over southwest Yukon Territory from March 12 to March 25, 1994. The dataset includes seven 1:50,000-scale maps covering NTS sheets 105 C/5, 12 and 105 D/8,9, produced for the Yukon Prospectors' Association. Maps include total field magnetics, electromagnetic anomalies, filtered VLF, calculated vertical gradient magnetics, and resistivity measurements at three frequencies.
A report from the Government of Yukon focuses on exploration criteria for valuable gemstones like ruby, sapphire, emerald, and minerals found in pegmatites. It provides background information, physical characteristics, deposit geology, and specific guidelines for exploration. The report applies these criteria to Yukon geology and was last updated on April 17, 2026.
Ten intrusive units provide new U-Pb age data bracketing polymetallic mineralization in the Freegold Mountain project area. The data indicates economically important mineralizing events occurred over a period of at least 40 million years. The dataset is published by the Government of Yukon and was last updated in April 2026.
Wernecke breccia comprises numerous intrusive hematitic breccia zones exposed in the Wernecke and Ogilvie mountains of central Yukon. The dataset describes the development of these zones in the Slats Creek (106 D/16) map area, including their emplacement into Middle Proterozoic strata and associated mineralization of Cu, U, Co, Ag, and Au. It was published by the Government of Yukon and last updated in April 2026.
Geological mapping at 1:50,000 scale was conducted during the 1988 field season south of Whitehorse. Rocks from the Atlin Terrane, Whitehorse Trough, and Coast Plutonic Complex are represented, bounded by the Nahlin thrust fault. Mineral occurrences are spatially related to the Nahlin Fault and the Tally Ho Shear Zone.
Placer gold alloy compositions and mineral inclusions from the Dawson Range in Yukon link surface deposits to specific porphyry and epithermal mineralization sources. The data, published by the Government of Yukon, establishes a generic Bi-Pb-Te-S signature for gold in Cu-Mo (-Au) porphyry systems. This signature can be applied to mineral exploration in areas where the relationship between placer and lode gold is unclear.
Yukon Territory subsurface data contains formation tops for 73 oil and gas wells drilled between 1957 and 2005. The Government of Yukon compiled this dataset in collaboration with the National Energy Board, using wireline logs exclusively. Data is presented in both imperial and metric units and is complemented by a stratigraphic correlation chart.
Southern Yukon's Skukum Creek deposit features an east-trending sinistral strike-slip system bounded by the Berney Creek and Goddell faults. This dataset from the Government of Yukon provides a detailed evaluation of structure and alteration related to gold- and silver-rich, base metal-bearing veins, completed as part of a 2002 mineral exploration program. It proposes a geological model for identifying prospective structures.
Aerial lidar data from 2014, 2018, 2019, 2020, and 2022, along with physical monitoring stations, track a slow-moving rock-slope deformation across from Dawson, Yukon. The dataset documents movement rates up to 11 cm/yr, road subsidence, expanding tension cracks, and rockfall. It is produced by the Government of Yukon and includes ongoing terrestrial lidar analysis and near-real-time monitoring installed in early 2023.
A 25 km long east-west belt of hydrothermal vein systems in central Yukon hosts silver-lead-zinc deposits. The Government of Yukon provides data on mineralogical zones, including pyrargyrite, siderite, galena, sphalerite, freibergite, pyrrhotite, arsenopyrite, calcite, boulangerite-jamesonite, and quartz-arsenopyrite assemblages. Higher gold values are recorded in specific zones.
Government of Yukon provides a geological report on the Klaza Au-Ag-Pb-Zn-(Cu) deposit in the Mount Nansen district. The report integrates field observations with archival Cu-Au assay data to infer a two-stage porphyry-epithermal system. The dataset was last updated on April 17, 2026.
380 meters of cyclic sedimentary rock in the Blow River Formation contain about 7 x 10^8 tonnes of P2O5. The dataset describes a high-latitude phosphorite and ironstone deposit within the Mid-Cretaceous flysch of northern Yukon, likely compiled by the Government of Yukon. The record was last updated on 2026-04-17.
The Brewery Creek gold mine is a bulk tonnage, heap leach operation located 57 km east of Dawson City, Yukon. Gold mineralization is hosted by intrusions of the mid-Cretaceous Tombstone Plutonic Suite and Silurian to Carboniferous clastic metasedimentary rocks. The dataset describes the deposit's structural setting, including faulting, intrusion phases, and the Reserve trend mineralization zone.
Weasel Lake map area (105G/13) in east-central Yukon contains surficial geological mapping and till geochemical sampling data. The Government of Yukon conducted this work to better understand mineral potential in the Finlayson Lake belt, an area with several volcanogenic massive sulphide deposits. The dataset was last updated on April 17, 2026.
Geological survey data describes the rock formations, structural features, and mineral occurrences within the Gravel Creek (105B/10) and Irvine Lake (105B/11) map areas in southeastern Yukon. The dataset details the Cassiar and Slide Mountain terranes, granitic intrusions, thrust faults, and mylonite zones. It was published by the Government of Yukon and last updated on April 17, 2026.
A geological dataset detailing stratigraphic correlations in the western Ogilvie Mountains of Yukon. It contains findings from investigations of sedimentary units in the Tatonduk and Coal Creek inliers, proposing refinements to regional nomenclature. The data was published by the Government of Yukon and last updated on April 17, 2026.
Intrusive rocks from the Nahanni region, southwestern Northwest Territories and southeastern Yukon, are analyzed. The dataset likely contains geochronological and lithogeochemical measurements, including U-Pb and Ar-Ar ages ranging from 97.5 to 95 Ma with cooling periods of 0.5 to 3 million years. It was published by the Government of Yukon and last updated in April 2026.
