SUMMARY OF 1990 EXPLORATION ACTIVITIES

I:kø SUMMARY
The 1990 geophysical program completed on the Fort Fitzgerald and Robert Creek
Projects was conducted to ground verify airborne magnetic anomalies postulated to have
kimberkte diatreme sources. The ground magnetic surveys were completed by an in-
house crew during late May and early April, 1990, on five airborne magnetic anomalies
interpreted from Geological Survey of Canada (GSC) airborne magnetic data.
Modelling the ground magnetic data collected over all anomalies indicates that the
magnetic sources occur within the crystalline basement. All modelled parameters are
within the limitations of kimberlitic diatremes.
Diamond drilling was completed on 3 anomalies within the Fort Fitzgerald area
All holes intersected magnetite-rich granite to granulites. Based on drill results it 15
