Our Senior Technical Professionals
Peter Webster is the President of Mercator Geological Services Limited and has worked as a geologist and senior manager in the resource industry with both small and large mineral exploration companies for over 30 years. He is a Professional Geoscientist registered with the Association of Professional Geoscientists of Nova Scotia and with the Professional Engineers and Geoscientists of Newfoundland and Labrador. He graduated from Dalhousie University with a B.Sc. in Geology in 1981 and holds a Certificate in Environmental Management from the Technical University of Nova Scotia, 1996 (C.E.M.). He has provided professional oversight on property assessment, technical assessments, project design and program implementation for projects relating to precious metals and base metals as well as industrial mineral commodities for clients in Canada, Mexico, Australia, South America, Africa and Russia.
Michael Cullen is the Chief Geologist at Mercator Geological Services and is a graduate of Mount Allison University (B.Sc., Hons.) and Dalhousie University (M.Sc.). He is a Professional Geoscientist registered with the Association of Professional Geoscientists of Nova Scotia, Professional Engineers and Geoscientists of Newfoundland and Labrador and the Association of Professional Engineers and Geoscientist New Brunswick, and is a Director of the Mining Association of Nova Scotia. He has over 30 years of combined experience as a geologist and/or Senior Manager within the mineral exploration industry and, more recently, as a geological consultant to government and industry. He has been employed with Mercator Geological Services Limited since 2001. Technical assignments have included locations throughout Canada as well as in the United States, Africa, Australia, Bolivia, Columbia, Chile, Finland and Russia. He has a strong background in detailed geological evaluation of mineral deposits with specific experience in precious metals, uranium, base metals and coal. He has also been involved in exploration and assessment of other commodities, including barite, gypsum, limestone, marble and coal bed methane.
Matthew is a graduate of Dalhousie University with Combined Honours in Earth Sciences and Biology and concentration in Environmental Studies. He joined Mercator in 2004, and has since focused on the evaluation and management of various geological projects through the use of Surpac© 3D software to reporting standards of National Instrument 43-101. This has involved design of diamond drill hole programs, drill hole database management, 3D wireframe and solids generation, geological interpretation, geostatistical analysis and block model resource estimations. Matthew has experience with various deposit styles present in Eastern Canada, including coarse-grained and disseminated gold, carbonate hosted base-metal, and porphyry polymetallic mineral deposits. In coordination with senior staff, his experience in deposit modeling through the use of Surpac© 3D software provides clients with management and support services through various project phases, including historic drilling database evaluation and validation, design of new drilling programs and completion of block model resource estimations.
Stewart graduated from Saint Mary’s University in 2002 with a Bachelor of Science with honours in Geology. He joined Mercator Geological Services in 2007 as a field geologist and is registered as a Professional Geologist with Association of Professional Geoscientists of Nova Scotia. Stewart has extensive experience with supervising diamond drill and reverse circulation drill projects in exploration for base metals and gold, as well as, bituminous well site and drill site remediation projects. Field work also has included geochemical sampling, mapping, prospecting and gas absorption sampling. In the office he has participated in research, graphical presentation, mapping, data compilation and verification, as well as the writing of technical and property reports.
Mike is a graduate of Memorial University of Newfoundland (B.Sc. Hons.) and the University of Ottawa (M.Sc.). Mike joined Mercator in 2018 and is a Professional Geoscientist registered with the Association of Professional Geoscientists in Nova Scotia (APGNS). He has more than 5 years experience as a project manager and project coordinator for mineral exploration, environmental consulting, and oil and gas development projects in the provinces of Newfoundland, Nova Scotia, Saskatchewan and Alberta. Specifically, Mike has experience in exploration for precious metals (gold and copper), industrial minerals (gypsum), uranium, and offshore oil and gas and heavy oil development projects. Mike also has experience in environmental assessments, exploration targeting and related business development initiatives. Mike is very active on a professional level and is currently sits as the Chair of the Student Committee and the Secretary of the Mining and Energy Committee for the APGNS.
Shaun holds a B.Sc. (Hons.) Earth Science from Carleton University and an M.Sc. in Geological Science from Queen’s University. He is a Professional Geoscientist (P.Geo.) with the Association of Professional Geoscientists of Nova Scotia. Shaun has over eight years of exploration experience in the Yukon, Ontario, Quebec and Nova Scotia. He has worked in a range of deposit environments including epithermal, orogenic and intrusion-related Au and carbonate-hosted Pb-Zn. He has a strong background in 3D geological modelling using Leapfrog, Datamine, and Target. As part of our resource modeling team, Shaun uses these skills to interpret and model complex ore bodies as part of a mineral resource estimate and to provide geological control on grade continuity and geotechnical conditions. Shaun specializes in expressing and solving geological problems using computational and data science methods and is experienced using Python for processing and analyzing exploration data. In this role, Shaun was part of the multidisciplinary team that developed Goldcorp and IBM’s award-winning Goldcorp Cognitive Journey project.
Ryan holds a B.Sc. (Hons.) and M.Sc. in Geology from the University of Manitoba and has been completing a PhD dissertation and teaching at Dalhousie University. He has prior experience as an exploration geologist supervising day-to-day operations including core-logging, managing exploration geologists and geo-technicians. He also worked as part of a team of geologists that developed 3D ore models on projects in northern British Columbia Ryan is currently responsible for sophisticated data analyses and database development to support prospectivity and targeting strategies. Through the use of XRF, Magnetic Susceptibility and TerraSpec, Ryan is developing unique geochemical, magnetic, or mineralogical signatures for specific deposit types.
