What Dias Geophysical does

Dias Geophysical is a privately held Canadian geophysical services company founded in 2014 and headquartered in Saskatoon, Saskatchewan. The firm develops and deploys proprietary ground and airborne survey systems used primarily by mineral exploration companies to image subsurface geology in three dimensions. Core technologies include the DIAS32 distributed array 3D DCIP system, QMAGT Full-Tensor Magnetic Gradiometry using SQUID sensors, QAMT passive airborne EM (AFMAG), Magnetotellurics, CSAMT, Sub-Audio Magnetics variants (SAMSON, HELISAM, UAVSAM), HeliSAM semi-airborne EM, high-power borehole EM, and the patented DIAS-LS lightning mitigation system. Much of the survey equipment — including the GS5000 high-power transmitter — is designed and manufactured in-house at the Saskatoon facility.

Dias operates as a project-based professional services company, generating revenue through survey design, data acquisition, processing, and 3D modeling engagements on a per-project basis. Clients span enterprise mining majors (NexGen Energy, Hudbay Minerals, Seabridge Gold, Freeport-McMoRan) and mid-market juniors (Doubleview Gold, Hercules Metals, VR Resources, ACME Lithium, Power Metallic Mines, Alliance Resources). Distribution is led by a dedicated sales manager and country managers in Chile and Mexico, supported by an active presence at PDAC, KEGS, Discoveries, Stanford Mineral-X, and ASEG. Datasets are processed through the proprietary DIAS CARAVEL cloud computing platform using SimPEG inversion codes.

Operations span at least 15 countries across six continents — including Canada, Australia, Chile, Mexico, Argentina, Peru, Saudi Arabia, Mali, and Zambia — with offices in Saskatoon, Toronto, Vancouver, Brisbane, Santiago, and Mexico City/Monterrey. The mineral exploration sector accounts for the majority of project work, with secondary applications in groundwater/environmental and engineering geophysics. Growth has been both organic (new Saskatoon HQ in May 2022) and inorganic, with the acquisitions of Discovery International Geophysics in January 2023 and Australia's Gap Geophysics in July 2024. The company employs approximately 100 people with over 15% in R&D, and received the Saskatchewan ABEX Innovation award in September 2025.

Core offering

Dias Geophysical provides proprietary ground and airborne geophysical survey services for mineral exploration and related applications. Services include 3D DCIP and resistivity, full-tensor magnetic gradiometry, magnetotellurics, CSAMT, and SQUID-based electromagnetic surveys, with data processing and 3D inversion executed on the proprietary DIAS CARAVEL cloud platform.

Product overview

Dias Geophysical is a geophysical services company offering a portfolio of proprietary ground and airborne survey technologies. The core product suite includes the DIAS32 3DIP/Resistivity system for ground surveys, QMAGT Full-Tensor Magnetic Gradiometry for airborne operations, and QAMT Passive Airborne EM systems. Additional technologies include Magnetotellurics (MT), CSAMT, Sub-Audio Magnetics (SAM variants including HELISAM and UAVSAM), SQUID-based electromagnetic sensors, and borehole EM systems. The company also offers DIAS CARAVEL cloud computing for 3D inversion modeling. Services encompass ground geophysical surveys, airborne surveys, 3D imaging, and survey design for mineral exploration, groundwater/environmental, and engineering sectors. Recent acquisitions of Discovery International Geophysics (2023) and Gap Geophysics (2024) expanded the technology portfolio.

Partnerships

Five partnerships are on record, tiered core and minor.

• Power Metallic MinescoreStrategic or Co-development Partner · 27 May 2026Power Metallic contracted Dias for advanced geophysical surveys (SQUIDs, gravity, and Ambient Noise Tomography) at the Nisk Project in Quebec. Expanded 2026 program includes 30,000m of exploration drilling and regional lake sediment survey, leveraging Dias' state-of-the-art techniques for deep Ni-Cu-PGE targeting. Property expanded to approximately 330 km² following 2025 land acquisitions. Survey mobilization currently underway.
• GAP GeophysicscoreStrategic or Co-development Partner · 1 July 2024Dias acquired Australian company Gap Geophysics in July 2024, announced July 1, 2024 across multiple sources (PR Newswire, diasgeo.com, PR Asia). Acquisition expands Dias' capabilities globally and enhances service offerings. Gap Geophysics had a long history of collaboration with Dias including co-development of the HeliSAM system. Deal aims to leverage synergies and improve geophysical technology access across sectors like mineral exploration and environmental management. Gap office in Brisbane, Queensland now serves as Dias' Australia presence.
• Discovery International GeophysicscoreStrategic or Co-development Partner · 13 January 2023Dias acquired Discovery International Geophysics in January 2023. Discovery was founded in 1996 by Dennis Woods and Brent Robertson, both now integrated into Dias (Dennis Woods serves as Director). Discovery brought complementary technologies including HeliSAM, SQUID EM systems (with Supracon), borehole EM services, and the patented HeliWinder system. Acquisition broadened Dias' technology portfolio significantly. Dennis Woods: 'We are very pleased to hand over the reins of Discovery, an extremely capable group of geoscience and mineral exploration professionals, to new leadership at Dias.'
• Ground Geophysical Survey Safety AssociationminorOthers · 1 September 2022Dias is an active member of the Ground Geophysical Survey Safety Association, contributing to industry safety standards and best practices for field geophysical operations.
• Supracon AGcoreTechnology or IntegrationLong-standing technology partnership with Supracon AG of Jena, Germany for SQUID (Superconducting QUantum Interference Device) sensor development. Supracon has over 20 years of SQUID development history. Supracon sensors are used in Dias' QMAGT (Full Tensor Magnetic Gradiometry) and QAMT (Passive Airborne EM) systems. SQUID sensors operating in liquid helium bath provide unmatched sensitivity (<50 fT/√Hz for QAMT, <100 fT/(m√Hz) gradient noise for QMAGT). Dias showcases Supracon technologies at international events including German Federal Ministry of Economics and Climate Protection Innovation Day.
