Sean Hicks, P.Geo.

Project Geologist

Sean is a professional geologist that has been working in mineral exploration since 2018 with expertise in all facets of early greenfield to brownfield exploration. He has experience with a wide variety of commodities from base and precious metals to battery minerals, across a multitude of deposit types including VMS and porphyry copper systems to BIF-hosted and orogenic gold deposits.

Working in remote settings across Canada, from the Arctic, Northern Ontario and British Columbia, Sean has gained a fond appreciation for logistics and is proficient at both the planning and execution phases of early exploration, from designing soil and till sampling grids to managing diamond drill and mapping programs.

Sean has received his honours degree in earth sciences from Carleton University, he is a member of the Society of Economic Geologists (SEG) and of the Professional Geologists of Ontario (PGO).

Jeffrey Enright, MSc, P.Geo.

Associate Geologist

Jeffrey has worked in mining and mineral exploration since 2012. He is a professional geoscientist with experience in running drill programs, making detailed observations at the micro- to macro-scale, and integrating those observations with geophysical inversions to develop interpretations and geological wireframes in a 3D environment. His experience spans from early-stage exploration on Ni-Cu-PGE, gold and uranium projects, to later stage resource definition involving the development of block models and technical reports.  

His interests in mineral deposits reside equally in the geosciences and in the economic factors that determine whether a mineral asset can be developed into an ore deposit. As such, he has applied his financial background in the mining development and production sectors and is experienced in developing and maintaining cost forecasts, budgets and detailed mine schedules.

Jeffrey has completed undergraduate degrees in commerce from the University of Guelph and geology from Laurentian University, received an MSc from the Harquail School of Earth Sciences in 2017, and is a member of the Professional Geoscientists of Ontario (PGO).

Tony French, MSc

Senior Geologist

Tony is an experienced exploration geologist and project manager who offers over 30 years of diverse domestic and international mineral exploration experience in commodities such as diamonds, uranium, coal and lithium.

Tony’s specialization includes the planning and execution of reverse circulation (RC) and core drilling programs, Large Diameter Drilling (LDD) programs, both ground and airborne geophysical surveying, the completion of many types of geological sampling programs (till, soil, stream, rock, geochemical, bulk sampling) as well as infrastructure development and the management of remote field camps in many parts of the world.  He has worked on projects from greenfield prospecting through to final resource definition.

Tony has acquired experience across a wide spectrum of project management functions including exploration program management, technical/geological oversight, project and regulatory reporting, budgeting, accounting, contract negotiation, contractor supervision, and program logistics.

An extensive history of executing multi-disciplinary, multi-million dollar exploration programs for mineral resource discovery and evaluation with major mining companies such as De Beers, Cameco and Dominion Diamonds testifies to his expertise, competence and resourcefulness in the industry.

Tony graduated with a MSc in Geology from the University of Auckland, New Zealand. 

Elizabeth Zbinden, PhD

Senior Geologist

Elizabeth is a geologist and geochemist enthusiastic about ore deposits, mineral exploration, deposit development, and mining operations.   After earning a PhD from Stanford University School of Earth Sciences in 1995, she has been based out of northern Nevada.  She has worked on deposits not only in Nevada and surrounding Basin and Range states, but also Ontario, Alaska, Mongolia, and Laos.  She has extensive experience in Nevada’s two signature gold deposit types – Carlin-style and young volcanic epithermal – as well as porphyry and related copper deposit types, and a variety of other commodities and deposit types.  She enjoys field work, managing and supervising drilling, and developing the geologic story that emerges from drilling results.
