Whitehorse Copper Belt, Yukon (GSC Map Folio, 1909)

An original Geological Survey of Canada publication, Report on the Whitehorse Copper Belt, Yukon Territory (1909), issued as a map folio in its original paper envelope.

This early 20th century Survey material documents one of Canada’s historically significant copper mining regions in the Yukon. The set contains multiple folded geological maps and plates, including colour-printed geological maps illustrating stratigraphy, structure, and mineralized zones within the Whitehorse copper belt.

Publications of this type were produced as companion materials to formal Geological Survey reports and were intended for professional use by geologists, engineers, and mining companies. Surviving examples are increasingly scarce, particularly when retaining their original envelope and a complete or near-complete set of maps.

The envelope shows wear consistent with age, including edge wear and creasing. The maps themselves remain well-preserved, with strong colour and clean paper, making this an attractive and historically important example of early Canadian geological mapping.
