Updates to the Yukon Geological Survey’s mineral potential mapping methodology

This paper serves as an update to an earlier paper published by the Yukon Geological Survey: New mineral potential mapping methodology for Yukon: case studies from the Beaver River and Dawson regional land use planning areas (Bullen, 2020). Since the release of the earlier paper, a number of the methods have been modified, and new techniques introduced. These are incorporated into this update paper — the reader is referred to the earlier paper for details of the method itself. Mineral potential maps have thus far been completed for the Beaver River watershed, and the Dawson, Teslin, Na-Cho Nyäk Dun, and Ross River regions. There have been significant updates made to the mineral potential mapping method: Modifications to buffer distance and factors (these are an important fuzzy logic (i.e., non-Boolean) component of the mineral potential mapping process) to enhance mapping outcomes. The introduction of an in-house generated, machine learning algorithm (unsupervised, clustering-type) to classify mineral potential in order to remove the potential for human bias. The method replaces the statistical, areas-under-the-curve approach used previously. A new method for delineating…
