Yukon Mineral Exploration Assessment Reports Since 1950s

Over 7,500 reports document mineral exploration activity in Yukon since the 1950s. Each record represents a report with polygon geometry for the work area and includes key information such as report number, title, author, year, claims, property name, expenditures, and hyperlinks to scanned documents. The dataset is intended for mining companies, prospectors, land use planners, First Nations, and regulators.

Use Cases

• Analyze spatial patterns of exploration activity by mapping report polygon geometries over time.
• Study trends in exploration expenditures by year and property name to identify investment cycles.
• Link report number and title to scanned documents via hyperlinks for archival research and validation.
• Examine the distribution of claims and author affiliations to understand industry participation.

Strengths

• Contains over 7,500 individual assessment reports.
• Records span from the 1950s to present, providing long-term temporal coverage.
• Includes polygon geometry representing the specific area where exploration work was performed.
• Key attributes such as report number, author, year, and expenditures are captured for each record.

Limitations

• More recent reports are confidential and not included in the public records.
• Sample data and column definitions are unavailable, complicating initial schema understanding.
• Data is provided only in ESRI REST and HTML formats, which may require specialized GIS tools for full analysis.
