Dr. Armstrong has more than 30 years of combined experience in mining, mineral exploration, and government. Dr. Armstrong was with Lucara Diamond Corp.

for more than 10 years where he was the Vice President of Mineral Resources and then in 2018 the Vice President of Technical Services. He was directly involved in the implementation of innovative and transformative diamond recovery techniques and responsible for modelling the unique diamond size distribution of the Karowe Diamond Mine. Dr. Armstrong led the Lucara team through study phases and ultimately the start of underground mining in progressing the Karowe underground expansion project.

Dr. Armstrong has been involved in the planning and execution of successful diamond exploration and sampling programs ranging from generative to delineation and valuation. Dr. Armstrong spent his early career working on gold projects and mines in Yellowknife, Red Lake, and the Hope Bay Greenstone Belt.

Dr. Armstrong was the Hutchison Visiting Chair for Mineral Deposits at the University of Western Ontario from 2008 to 2010 where he served as a visiting professor, educating and mentoring the next generation of geologists-some of which have since become notable executives in the exploration industry. Dr. Armstrong received an undergraduate degree and his Ph.D. in Geology from the University of Western Ontario, where his Ph.D. focused on the silicate and sulphide mineral chemistry of free-milling and refractory gold ores of the Con Mine, Yellowknife.
