The Ronacher McKenzie Geoscience Team

The Ronacher McKenzie Geoscience Team has decades of experience in exploration. Our geologists and geophysicists have worked on five continents (North America, South and Central America, Asia, Africa and Europe). We explore in many different geological settings, from old cratons to young volcanic arcs. We have worked on a variety of deposit types, including orogenic, VMS, Sedex, MVT, kimberlite, porphyry, epithermal, sediment hosted Cu and orthomagmatic. The commodities our specialists have worked on range from potash and uranium to diamonds and from base-metals (Cu, Pb, Zn, Au, Ni) to precious metals (Au, platinum group metals). In geophysics, we have expertise in magnetic, electromagnetic, IP/resistivity and gravity, ground penetrating radar, CSAMT, and it all forms: ground, airborne and borehole. Our geophysicists also work with physical rock properties to help understand and characterize mineralized rocks. We speak several languages, including: English, French, Spanish, German, Farsi and Albanian. Our GIS specialists has more than 20 years of experience with geographic information systems and data analysis in 2D.

Our team focuses on our clients’ needs and provides them with custom-tailed solutions for their exploration needs.

Jeffrey Enright, MSc, P.Geo.

Geologist, Project Manager

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).

Darcy has over 25 years experience in acquisition, processing, inversion, and interpretation of a wide range of airborne and ground geophysical techniques. He has worked on 6 continents on green- and brownfields projects exploring for diamonds, base and precious metals, and petroleum, as well as water resource monitoring and hazard mapping.

Darcy is a member of Professional Geoscientists Ontario (PGO), the Society of Exploration Geophysicists (SEG) and is a past executive member of the Canadian Exploration Geophysical Society (KEGS) from 2017 to 2020.

R.W. Avery

Manager, Field Geology

R.W.(Ron) Avery has acquired three decades of field experience working on a wide variety of uranium, gold and diamond exploration projects ranging from grassroots investigations through to corehole drilling of advanced prospects to deposit status. He is accredited with the discovery and delineation of three gold deposits in the La Ronge Gold Belt in Saskatchewan (Roy Lloyd Mine, EP Deposit, Birch Crossing Deposit) and has evaluated gold prospects and deposits elsewhere throughout Canada, the United States, and south Asia (Myanmar, the Philippines, Indonesia). He is also one of the team members responsible for the discovery and initial delineation of the Fort à la Corne kimberlite cluster in Saskatchewan in 1989.

Mr. Avery’s areas of specialization include: the planning, execution and interpretation of various geochemical surveys (till, soil, MMI, soil gas hydrocarbon); the vectoring of multi- element geochemical data in the definition of hydrothermal alteration towards economic mineralization; the completion of bedrock and trench mapping programs and the interpretation of structural data; and the planning and execution of reverse circulation and corehole drilling of greenfields prospects through to final resource definition.
