Overview of Results from the Greenstone ... - Geology Ontario

A regional-scale project of this kind must balance the conflicting demands of covering the
designated area and of obtaining a data density adequate to define reasonably well-constrained
metamorphic exploration targets. Definition of many of the metamorphic anomalies with gold potential
that are outlined on the metamorphic map of Timmins–Kirkland Lake area (see Figure 27; Thompson
2005) can and should be improved with additional sampling in key target areas. More complete analysis
and interpretation of the spatial relationships between the intensity of strain, the type and intensity of
alteration, and metamorphic zone boundaries is required. Future work should address also the low
density or absence of data in the northwest, south-central and northeast sectors of the map presented here
and extend metamorphic mapping to the north and southwest in Ontario and eastward into Quebec.
Figure 29. Underground data projected onto vertical profiles oriented parallel and perpendicular to the main structural trend
through the Dome and Paymaster mines indicates that metamorphic anomaly is a linear feature (from Thompson 2005, p.19).
