This update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). The data set includes the bedrock geology, faults and contacts, geochronology and map index; published by Yukon Geological Survey (January 2022). New digital data are being released incrementally and will be updated regularly as new parts of the compilation are ready. Any errors noted by the user of this data should be reported promptly to the Yukon Geological Survey.

Yukon Digital Geology presents a variety of geoscience data sets in digital format on the geology of Yukon. Included are syntheses of bedrock geology and glacial limits, compilations of geochronology, paleontology, mineral occurrences, oil and gas wells, and a compendium of aeromagnetic images. A subset of a public domain topographic data set (Digital Chart of the World, by ESRI, Inc.) is included for georeference purposes. For ease of use, data sets are divided geographically into 45 map tiles corresponding to the National Topographic System (NTS) 1:250,000 quadrangles. Data sets spanning the entire Yukon are also included. Each theme for all of the 45 map tiles is presented in two projections; an Albers Equal Area projection and UTM coordinate system. Vector data files are also presented in several different file formats (ArcInfo coverages; Interchange (*.e00), dBase (*.dbf), shapefiles (*.shp), and image data files are presented in band interleaved by line (*.bil), and tagged image file format (*.tif).

Contains all the digital data files that were assembled or created during the Finlayson Lake TGI project. It includes two MS Access databases of field observations (bedrock and surficial), scanned and digitized maps, a series of georeferenced images (geophysical and LandSat), and a collection of reports from the Yukon Exploration and Geology (YEG) series. The data are presented in formats that can be viewed using four software products. Adobe Acrobat Reader 5 and ESRI ArcExplorer 2 are provided. Microsoft Internet Explorer is required to view the interface screens (Netscape may not work properly). A runtime version of Microsoft Access is also included to view the field databases if the user does not already have Microsoft Access installed on their computer. These four software products, or equivalent licensed versions, must be installed to utilize the full interactive capability. The spatial data can also be manually opened or imported.

The Yukon bedrock geology map is in constant evolution as new mapping, geochronology and other geoscience studies improve the stratigraphy, and bring more detailed relationships into focus. The Digital Bedrock Geology GIS dataset used to produce this map is regularly updated and can be downloaded from the Yukon Geological Survey’s website:http://data.geology.gov.yk.ca/Compilation/3. Users are advised to consult the website regularly to ensure they are working with the latest version of the geodatabase or shape files. This Open File map is based on the 2022 version of the bedrock geology dataset; it is accompanied by a detailed Legend (Sheet 2) that summarizes current understanding of rock assemblages and stratigraphic units. The Yukon bedrock geology map can also be viewed and queried online using the Yukon Geological Survey interactive map service: https://yukon.ca/en/yukon-geology#bedrock-geology.

These georeferenced pdf maps contain the most current bedrock geology information in Yukon. They are intended for use in software such as Avenza PDF Maps. The geological data used to create these maps can be downloaded at https://data.geology.gov.yk.ca/Compilation/3. These maps are subject to periodic updates. The Yukon Geological Survey welcomes any revisions or new geological information. Any questions or comments can be directed to geology@gov.yk.ca.

This publication is intended as a snapshot of the hard rock mineral resources of Yukon. It is up-to-date as of December 1, 2023. The tables herein have been compiled from information derived from Yukon MINFILE – A database of mineral occurrences, and from various technical reports and information filed in SEDAR (system for electronic document analysis and retrieval). This document does not include cut-off grades for resources and reserves. Numbers have been rounded for readability. Tonnages and grade are provided in metric measure – converted from imperial as required. Total contained metals are estimated as a result of tonnage multiplied by grade; reported values are converted to either metric or imperial as required. Amounts are for all deposits/zones on the property. Deposit resources are identified as being compliant with either the minimum requirement for mineral resources and reserves as defined by the Canadian National Instrument for the standards of disclosure for mineral projects (NI 43-101), the Australasian code for reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC) standards or the disclosure requirements for the mining companies in the United States, in accordance to the Securities and Exchange Commission Industry Guide 7 (S-K 1300). Deposits that are not compliant with these definitions are identified as historical estimates. The Owner/optionee indicate the company owner as stated in the resource estimate or on the company website. In the case of historical resource calculations where there is no resource estimate or website available, the owner is the registered quartz claim holder. The reader is encouraged to refer to the original reference for detailed information. We accept no responsibility for any errors or omissions.
