Map and report listing information on 419 mineral ocurrences in Yukon that contain noteworthy amounts of gold and/or silver. A capsule description of the occurrence's geology is present along with a list of the significant ore minerals. This is followed by information on the metal content of the occurrence and extent of exploration and development work. Accompanying this report is a 1:2,000,000-scale map of gold-silver deposits and occurrences in the Yukon Territory.

Geological map (1:1,000,000 scale) of the Yukon Territory, including platinum potential, platinum occurrences, a list of selected geological units with PGE potential, density of geochemical anomalies for nickel, chromium and cobalt and selected stream silt anomalies for nickel, cobalt and chromium. Accompanying the map is a brief report describing: Yukon MINFILE occurrences with reported PGE mineralization and anomalies; interpretation of regional silt geochemical anomalies; placer PGEs in Yukon; gravity anomalies; and PGE potential in Yukon (concepts and localities).

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.

This report includes a summary of the mineral exploration history of Yukon, an outline of the geology of its southern part, and brief descriptions of the most important mineral occurrences. The report brings together current ideas of the geology and examines the metal deposits in this context.

One third of the gold and gold-silver deposits in Yukon were examined and sampled in 1980 to establish a framework of geology and rock chemistry from which variations within and between deposits could be detected and evaluated. Lithologic units within the samples were analyzed for Au, Ag, B, Mn, Cu, Zn, As, Se, Tl, Pb, Bi, Sb, Te, W, Hg, Mo and Cd - elements commonly associated with precious metal deposits. A problem which prevented systematic sampling of many deposits is the lack of underground access and the locally intense oxidation of vein outcrops. Three aspects of the rock geochemistry are discussed:: 1) different levels of element concentration in the deposits and implications regarding pathfinder elements; 2) distribution of elements in deposit types; and 3) element distribution in specific deposits. The geology of the deposits is summarized from published works and interpreted in light of recent theories on gold deposits. This report emphasizes common features of the deposits and several genetic models.

The following tables have been compiled from information derived from the Yukon MINFILE 2008 — An database of mineral occurrences (Deklerk, 2008), and from various technical reports and information that have been filed in the SEDAR system by, or on behalf of, public companies. Reserve and resource figures presented are not calculated by Yukon government personnel, but are quoted from referenced industry sources, publications, assessment and/or technical reports, etc. (see next page). The reader is encouraged to refer to the original data for detailed information.
