Mineral exploration teams routinely face a familiar set of obstacles: inefficient field data collection, high construction costs tied to traditional survey methods, weak responses in deep or high-resistance environments, and the difficulty of integrating scattered geological, geophysical, and engineering data. When data quality issues are identified only after demobilization, crews may need to return for repeat measurements, increasing cost and delaying interpretation.
Shenzhen Geomative Technology Co., Ltd., operating under the Geomative brand, develops geophysical instruments and digital subsurface-data tools for mineral exploration, hydrogeology, engineering geology, and environmental monitoring. Established in 2011, the company provides resistivity/IP systems, TEM equipment, magnetometers, logging systems, monitoring products, and the DIGspace geoscience platform.
Resistivity and IP Imaging Systems for Mineral Exploration
Electrical resistivity and induced polarization methods can help investigate subsurface electrical contrasts. In mineral exploration, these contrasts may be associated with lithology, alteration, structures, conductive minerals, groundwater conditions, or other geological features.
They do not provide a direct confirmation of mineralization, ore grade, or mineral resources. Whether a target can be identified depends on the contrast between the target and surrounding material, target size and geometry, depth, overburden, electrode layout, contact conditions, interference, and data quality.
GD-10 Resistivity and IP System
GD-10 is a single-channel resistivity and IP system with modular and upgradeable configurations. It supports electrical survey workflows using compatible accessories and can be applied with different electrode arrangements.
Its field interface provides measurement-data review functions that can help crews identify questionable records and decide whether remeasurement is needed before leaving the survey area. The exact field capability depends on the selected host unit, switching equipment, cable layout, electrode arrangement, power supply, and survey method.
In mineral exploration, GD-10 can be used to investigate electrical and IP anomalies associated with potential mineralization. Such anomalies should be interpreted together with geological information and verified through appropriate drilling, sampling, mapping, exposure, or laboratory work where the project decision requires confirmation.
GD-20 Multi-Channel Resistivity and IP System
GD-20 is a multi-channel ERT/IP system with 5- or 12-channel configurations, depending on the selected version. It supports a range of electrical survey methods and can be configured for surface, water-surface, underwater, borehole, and cross-hole work using compatible equipment.
Official GD-20 specifications list version-dependent power, voltage, current, method, and channel capabilities. A 9 kW transmit-power option is available for applicable configurations. Buyers should confirm the exact GD-20 version, required switching equipment, cable package, power source, field-accessory ratings, and software workflow rather than treating all GD-20 variants as identical.
GD-12, GD-22, and GD-32 Systems
GD-12, GD-22, and GD-32 are distinct models and should be compared by their individual specifications.
-
GD-12: 1 receiving channel, maximum transmit power of 7.2 kW, maximum transmit voltage of 1,200 V, maximum transmit current of 6 A, and no full-waveform acquisition.
-
GD-22: 6 receiving channels, maximum transmit power of 15 kW, maximum transmit voltage of 1,500 V, maximum transmit current of 10 A, and full-waveform acquisition.
-
GD-32: 12 receiving channels, maximum transmit power of 15 kW, maximum transmit voltage of 1,500 V, maximum transmit current of 10 A, and full-waveform acquisition.
All three models list 24-bit A/D conversion, 140 dB dynamic range, selectable 50 Hz or 60 Hz power-line rejection of at least 120 dB, and support for more than 1,000 electrodes.
Supported electrode count is separate from simultaneous receiving-channel count. The field configuration also requires compatible switching devices, cables, relay power, electrodes, and power supply. Maximum published power does not itself guarantee a given investigation depth or target detectability.
GT-10 TEM System for Conductive Target Investigation
Alongside resistivity and IP imaging, Geomative offers transient electromagnetic systems under the GT product line.
GT-10 is positioned for mineral, structural, and groundwater-related TEM investigation. Its product design uses a cylindrical central probe and an integrated field configuration. The exact transmitting arrangement, survey geometry, and field accessories should be confirmed for the selected configuration rather than assumed from the probe design alone.
TEM responses may help identify conductive contrasts related to geological structures, groundwater conditions, conductive mineralization, or other subsurface features. Investigation depth and resolution depend on target size, conductivity contrast, overburden, terrain, transmitter configuration, receiver performance, field noise, and interpretation assumptions.
A TEM response is not direct confirmation of an ore body, water-bearing structure, or mineral resource. Geological context and appropriate independent verification remain necessary.
DIGspace: Integrating Multi-Source Subsurface Data
Scattered geological, geophysical, and engineering data can complicate exploration interpretation. DIGspace is Geomative’s platform for multi-source data management, desktop analysis, web collaboration, three-dimensional visualization, anomaly interpretation, and related processing workflows.
Current platform documentation describes support for electrical survey, GPR, drilling-log, GIS, CAD, BIM, and other data types, along with ERT inversion and integrated two-dimensional and three-dimensional presentation.
For a specific project, buyers should confirm:
-
Whether the required instrument and file type are supported.
-
Which method modules are available in the selected software version.
-
Whether the needed workflow includes visualization, two-dimensional inversion, three-dimensional volume construction, or full three-dimensional inversion.
-
Which acquisition parameters, electrode coordinates, quality-control records, and metadata remain available after import.
-
Which export formats are supported by the selected device interface and method module.
Multi-source visualization does not by itself mean that a project includes joint inversion across all data types. Likewise, a three-dimensional visual model is not automatically a full three-dimensional inversion result.
Field Evidence: Mineral Exploration Case Studies
Geomative’s published case material includes a gold exploration project in Brazil. The project used a GD-10 Supreme 2D+/3D+ high-density electrical configuration with 24 channels and non-polarized electrodes to investigate electrical and IP contrasts associated with potential mineralization.
The survey supported interpretation of potential mineralization-related targets and follow-up exploration planning. The resulting anomalies should be understood as targeting information rather than direct confirmation of gold mineralization or mineral resources. Follow-up drilling, sampling, geological mapping, and laboratory analysis remain necessary where a resource decision is required.
In a separate underground project at the Beishan lead-zinc mine in Hechi, Guangxi, GT-30 TEM surveys were interpreted together with geological information for mineral and groundwater exploration. The published case reports interpretation of mineral-related and groundwater-related anomalies followed by exposure verification.
This case demonstrates a project-specific application of TEM in an operating mine. Its outcome should not be generalized to all mine settings without considering hydrogeological conditions, target properties, survey geometry, interference, and verification conditions.
Interpretation Boundaries and Responsible Use
Across resistivity/IP and TEM work, anomalies indicate physical-property contrasts rather than direct geological confirmation.
Electrical and IP anomalies can support geological interpretation and target prioritization. TEM responses can support investigation of conductive features and structures. Neither method should be used alone to confirm mineralization, ore resources, groundwater occurrence, or engineering conditions.
The responsible workflow is to use geophysical results to guide the next stage of work, then compare the interpretation with geological evidence and verify critical conclusions through drilling, sampling, exposure, inspection, laboratory analysis, or other appropriate methods.
Matching Equipment to Exploration Needs
Geomative’s GD and GT product lines provide different configurations for different survey tasks. The right selection depends on the actual exploration problem rather than on a single headline specification.
Before procurement, teams should define:
-
Target depth, scale, geometry, and expected physical-property contrast.
-
Preferred method or method combination.
-
Required channels, transmit capability, sampling mode, and waveform requirements.
-
Electrode count, cable layout, switching equipment, and power source.
-
Terrain, access, contact resistance, noise environment, and crew capacity.
-
Required software modules, data formats, interpretation workflow, and deliverables.
-
Field trial, quality-control, and verification requirements.
Geomative provides centralized and distributed switching equipment, high-density cables, and power-related accessories for different electrical survey layouts. The appropriate accessory package should be specified by the selected instrument model and survey design. Buyers should confirm compatibility, voltage and current ratings, field load limits, relay-power requirements, battery or generator needs, transport conditions, and spare-parts support before deployment.
By matching GD-10, GD-20, GD-12, GD-22, GD-32, GT-10, GT-30, and DIGspace capabilities to a defined survey objective, exploration teams can build a more traceable workflow from field acquisition to interpretation and verification.
