North America: Madsen gold

From 1938 until its closure in 1976, the Madsen gold mine in Ontario produced more than 2.4 million ounces of gold. SRK was commissioned by Claude Resources in March 2008 to convert the mine’s wealth of historical, paper-based geological data into a modern 3D geological model for the Madsen Gold project. Using scanned and geo-referenced cross-sections and maps of the deposit, SRK rapidly developed a 3D geological model. The model fundamentally improved understanding of the controls on gold mineralisation and formed the basis of a 3D mineral resource model.
