Graham is a minerals deposit geologist and regional mapper with a recent focus on collaborative studies of magmatic Ni-Cu-PGE deposits in ultramafic-mafic intrusions at convergent margins and potential linkages with Cu-Au alkalic porphyry systems in the Canadian Cordillera.

Education

University of Leeds (B.Sc., 1971)

Memorial University of Newfoundland (MSc., 1974)

The University of British Columbia (Ph.D., 1986)

Expertise

Before Graham joined the BCGS in 1987 as a Project Geologist, he was working as a mapping geologist in the mineral exploration industry in BC and Yukon, a Sessional Lecturer at UBC, and an Adjunct Professor at Queen’s University teaching volcanology/igneous petrology and supervising graduate student theses. Since joining BCGS Graham has been involved in mineral deposit studies throughout BC including Ni-Cu-Cr-PGE mineralization in ultramafic-mafic intrusions and Cu-Au-PGE deposits in alkali porphyry systems. Graham has also conducted regional mapping programs in northern Vancouver Island and the Toodoggone. More recently, Graham has become involved in TGI-4/TGI-5 partnerships studying Ni-Cu-PGE mineralization in an emerging class of ultramafic-mafic intrusions at convergent margins in collaboration with researchers at the GSC and UBC.
