This overview provides a summary of research highlights for 2022. Many of the projects described here are presented in more detail in the Yukon Exploration and Geology technical papers that are released with this Overview volume. Two highlights from 2022 are worth noting this year. First, 2022 marks the 30th anniversary of YGS. Since its creation, the Survey has grown and evolved into a multi-disciplinary organization that provides expertise across a range of disciplines (bedrock geology, regional tectonics, glacial history, geohazards and metallogeny) and excels at geoscience education and information management. The second noteworthy event to point out was the discovery of a mummified baby woolly mammoth (Nun Cho Ga) in June on Upper Eureka Creek. Two Survey staff had the privilege of assisting with the recovery of the mammoth and participating in the Tr’ondëk Hwëch’in First Nation ceremony that marked this scientifically and culturally important discovery. Jeff Bond subsequently mapped the discovery site in detail, documenting the conditions that led to the remarkable preservation of Nun Cho Ga.

The Yukon Geological Survey (YGS) had a busy year in 2019, welcoming seven new staff and initiating several new projects. In addition to its regular activities, the survey hosted a planning workshop with clients and stakeholders in April to identify gaps in Yukon’s geoscience knowledge base and engage participants in a discussion about their current and future information needs. The YGS holds these workshops every five years, and they are valuable for providing insights into research and exploration trends, generating ideas for new projects, and identifying opportunities for collaborative partnerships. As a backdrop for these discussions, participants were asked to consider how existing and emerging markets, climate change, societal needs and new technologies might influence how the YGS collects, manages and disseminates information. This paper provides both a brief overview of 2019 program activities and a summary of what was heard at the April planning workshop. Workshop discussions covered a broad range of topics and included both specific project ideas as well as general themes. The YGS has already initiated some of the projects that were proposed in April. The paper is organized based on the thematic breakout sessions at the workshop; current activities underway under each of the themes are presented first, followed by a summary of the input heard at the workshop.

The Yukon Geological Survey (YGS) has seen significant change over the last year, with eight new staff joining the team in 2024. This change has brought some new energy to the survey, enabling more visits to exploration projects and building the organization’s capacity to deliver geoscience. This report provides a snapshot of YGS’ staff and fiscal resources, and summarizes YGS’ 2024 activities and project highlights. Over the course of the year, YGS organized three workshops to assess current gaps in map coverage, seek input from clients about their needs, and consider how current trends such as interest in critical minerals and increasing frequency of landslides might influence YGS’ priorities in the future. Following each workshop, a list of project ideas for future work was compiled; these are summarized in this report. Gold prices in 2024 were high, averaging over C$3351 per ounce during the production season. This was a major driver for placer activity in the Yukon, which recorded the highest production on record since 1886. On a more somber note, the failure of the heap leach pad at Eagle Gold Mine in late June had a significantly negative impact on the First Nation of Na-Cho Nyäk Dun and the mineral industry in general. The medium to long-term effects of this incident on the environment and the mining sector are currently unclear.

Yukon Exploration and Geology (YEG) papers and the Yukon Exploration and Geology Overview are two of the main publications of the Yukon Geological Survey (YGS; Energy, Mines and Resources, Government of Yukon). Individual YEG papers, with colour images, are available in digital format only. The YEG Overview is available in digital format and in a limited colour print run. All YGS publications can be downloaded from our website, https://data.geology.gov.yk.ca/. Yukon Exploration and Geology 2023 contains up-to-date information on mining and mineral exploration activity, studies by industry and results of recent geological field studies. Information in this volume comes from prospectors, exploration and government geologists, mining companies and students, all of whom are willing to contribute to public geoscience for the benefit of the scientific community, the public and the mineral industry of the Yukon. Their work is appreciated.

The Yukon Exploration and Geology (YEG) volumes include two publications: Yukon Exploration and Geology Overview, and Yukon Exploration and Geology Technical Papers. These key annual publications from the Yukon Geological Survey (Energy, Mines and Resources, Government of Yukon) highlight geoscience research and activities across the Yukon from the previous year. The YEG Overview includes four papers that provide summaries of the Yukon Geological Survey’s staff activities, as well as exploration and development overviews for both the hardrock and placer industries in the Yukon. The YEG Technical Papers volume contains a number of current research reports on various geoscience projects across the territory. The YEG Overview is available in digital format and in a limited colour print run. The YEG Technical Papers volume is available in digital format only. All Yukon Geological Survey publications can be downloaded from our website, https://data.geology.gov.yk.ca/. As in previous volumes, YEG 2024 aims to provide the most up-to-date information on mining and mineral exploration activity in the Yukon, both in the hardrock and placer sectors. The success of YEG relies on the continued contributions from prospectors, exploration and government geologists, mining companies, and academic students, all of whom are willing to contribute to public geoscience for the benefit of the scientific community, the public, and the mineral industry of the Yukon. Their work is greatly appreciated. More importantly, I would like to acknowledge the support from our 14 Yukon First Nation partners whose lands and traditional territories we continue to work on. The mining industry and the valuable geoscience data that is gathered would not happen without their engagement and support. We look forward to strengthening and fostering honest and meaningful partnerships with all Yukon First Nations.

Like everywhere else around the world, 2020 was underscored in Yukon by the sudden spread of the COVID-19 virus and the drastic social and economic changes it precipitated. For Yukon Geological Survey (YGS), this meant a hasty retreat from offices in March, a reduced and modified field season, disruption of our client services, and uncertainties about the duration of the “new normal” and the impact it might have on Yukon’s communities and minerals sector in the long term. Relative to most regions of Canada, Yukon has fared relatively well and by June, the minerals sector was focused on how they could undertake exploration rather than how they might recover from a cancelled field season. Similarly, YGS managed to complete most of its planned field activities (albeit with a reduced scope), and to administer an expanded Yukon Mineral Exploration Program.

This is a re-release of data collected and published as the Yukon GEOPROCESS FILE between 1994-1996. The data set is a compilation of information and knowledge on geological processes and terrain hazards in the Yukon Territory. The original work was carried out in three phases from 1992 to 1995. Contractors performed the work under the supervision of the Environmental Geologist, Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada. The following individuals and companies were involved in carrying out the project: Mougeot GeoAnalysis, Aurum Geological Consultants Inc., L. Walton and C. Hart.
