1955-1956, Yukon Territory
Mine geologist at United Keno Hill Mines Limited in the Yukon Territory of northern Canada. Ores in this old mining district were silver-lead-zinc veins and lodes. Mapping,
evaluation, and guidance of mining operations in underground workings in several of the mines.
1957, Northern Ontario and Quebec
Continental Mining Corporation, exploring for Algoma-type iron-formation in Archean greenstones north of Sioux Lookout, Ontario, and for copper-gold ore at Chibougamau, Quebec.
The latter involved drilling from ice-covered Lac Doré for ores in shears in anorthosites of the Doré Lake Basic Igneous Complex. Produced composite geologic map of the Chibougamau Mining District.
1957-1962, Saudi Arabia
Economic Geologist at the Directorate General
of Petroleum and Mineral Resources, Jeddah, Saudi Arabia. Helped lead
field parties of Saudi engineers and geologists in regional mapping and
detailed investigation of mineral occurrences. Explored potential mining
areas, including ancient mining sites operated at the time of the
Prophet, during the Roman Empire, for massive sulphides (Um Ad Amar),
lode gold (Mahad Dhahab and Al Amar), silver-bearing veins, uranium
(Jebel Sayid), oolitic iron ore (Wadi Fatima), and many other prospects.
Most of the deposits were in greenstone belts, but the iron ores were in
sedimentary basins adjacent to the Red Sea rift.
1962-1967, Graduate Studies at McGill University
