What DGI Geoscience does

DGI Geoscience is a Toronto-based borehole geophysical services firm founded in 1997 that delivers turn-key subsurface data acquisition and interpretation for the mining, exploration, geotechnical, hydrogeological, and environmental sectors. The company operates four service categories: imaging (optical and acoustic televiewer, video inspection, 3D laser and sonar, borehole radar with up to 40m off-hole sensing), geophysical surveys (natural and spectral gamma, magnetic, electrical, fullwave sonic, density), hydrogeological measurements (NMR porosity and permeability, spinner and heat-pulse flowmeter, cross-hole resistivity), and directional and hole-inspection services (gyroscopic and magnetic deviation, caliper, cement bond log). It also provides consulting in stress estimation, off-hole structure analysis, geological interpretation, core logging facility modernization, and machine learning for geological data. Headquartered in Toronto with field offices in Elko (Nevada), West Valley City (Utah), Brazil, and Kazakhstan, DGI has completed 790+ projects across all seven continents, accumulating 389,006+ surveys, and counts tier-1 mining majors (BHP, Rio Tinto, Glencore, Vale, Barrick, Nevada Gold Mines, Kinross, Teck) and major engineering consultancies (SRK, WSP, Stantec) among its clients.

The firm monetizes exclusively through professional services on a project-based, custom-quote model with no public pricing tiers and an enterprise field-sales motion. Compact, helicopter- and boat-transportable equipment and 25+ years of operating experience in extreme environments (Arctic, desert, underground) enable deployment in locations where larger oilfield service providers do not compete. The company's slim-hole wireline logging capability, including surveying horizontal and up-dipping holes to 1,000m and stacking probes for simultaneous acquisition, is positioned as industry-leading. Go-to-market relies on SEG conference presence, LinkedIn case studies, client testimonials, and direct website inquiry, with field crews deployed to client sites rather than product shipments. The firm is privately held with no disclosed controlling investor other than a 2022 capital event from Canadian Shield Capital (undisclosed amount), and operates as an independent entity alongside sister company Kore Geosystems, which provides the SPECTOR Geo and SPECTOR AI platforms underpinning DGI's AI-enabled core logging offering.

Operations are led by President Chris Drielsma, supported by senior staff including Roxanne Leblanc (Senior Data Analyst, head of Data Processing and Interpretation), McLain Pray (US Sales Lead, formerly a Schlumberger well log analyst), Patrick Hooker (Technical Product Manager, ex-Rio Tinto Exploration, specializing in geophysics), Alejandro Rojas (Operations Manager), Reid Morrison (Field and Fleet Manager), and a geoscience team spanning consulting, processing, and field roles. The current product evolution is toward software-anchored recurring revenue via AI core logging and ML consulting, layered on the firm's core field-services base.
