George O'Reilly is a mineral deposit geologist with the Nova Scotia Department of Natural Resources where he has worked since 1976. He obtained his B.Sc. in 1976 and M.Sc. in 1988 from Dalhousie University where his main interests were the geochemistry of mineral deposits associated with granitic systems. From 1976-1993 he worked on a variety of geological mapping projects and mineral deposit studies mostly within the granitic terrains of Nova Scotia. In 1993, he took over supervision of the Mineral Inventory Project and helped bring the province’s Mineral Occurrence Database into the computer age. 

O’Reilly has represented the Department of Natural Resources on several interdepartmental and intergovernmental committees and working groups to deal with a variety of sensitive environmental issues. Most notable are the natural occurrence of elevated levels of uranium, radon and radioactive lead in groundwater and the issue of radon in air within homes and work places throughout the province. 

He became involved with CIM in 1992 when he became secretary of the local organizing committee for the CIM Annual General Meeting which was held in Halifax in 1995. Following that, in 1995, he assumed the task of representing the Geological Society of CIM as their Associate Editor of the CIM Bulletin, a role he still fills. 

O’Reilly currently serves on the Council of the Mining Society of Nova Scotia.
