Why the geoLOGr® Rock Analyzer
Standardize & Accelerate Drill Core and Crushed Rock Logging
Mineral exploration and mining teams face many challenges due to inconsistent visual logs, excessive re-logging, and delays in receiving results from the lab. The geoLOGr® fixes that. It replaces slow, subjective observations with rapid, reproducible outputs powered by proven, proprietary, data-driven hyperspectral data analysis methods.
- Dramatically improve drill core and crushed rock logging accuracy
- Reduce logging time by up to 75%.
- Capture compositional information that is invisible to the eye.
- Maintain a clear audit trail for compliance.
- Achieve reduction in project timelines from 6 years → 18 months.
- Unlock $1M–$20M+ savings per project by reducing drilling and geochemical sampling.
geoLOGr® Features & Specs
Compact, Robust & Field-Ready
The geoLOGr® hyperspectral rock analyzer consists of an extendable and height-adjustable, wheel-based metal frame that carries a movable sensor head with a hyperspectral point sensor and a high-resolution line-scan camera (35 μm per pixel). The sensor head moves at a constant speed over the entire length of the drill core, collecting data in a continuous and non-destructive manner down the centreline. The flexible design allows for deployment on the ground, on a tabletop, or above a roller table. It takes about one day of training for an operator to start scanning with the geoLOGr®.

How geoLOGr® Works
SWIR reflectance in, Lithotype™ insight out—connected to your workflow.
1. Scan
The geoLOGr® collects ~300 shortwave infrared (SWIR) reflectance spectra per meter in a non-contact and continuous manner, plus it also collects high-resolution colour photos, providing a detailed visual record of the drill core or crushed rock samples.
2. Process
Reflectance spectra are processed using our proprietary, cloud-based workflow–which includes the Lithotype™ Method—to deliver accurate, objective information for all rock types.
3. Decide
Outputs feed into your existing logging, visualization, or modelling software so teams align faster.

Advanced Data Processing
Unlock Deeper Insights with the Lithotype™Method
For about 10% of projects worldwide, mineral matching outputs and scalar calculations can provide valuable insights. For the remaining 90% of projects, more sophisticated methods of hyperspectral data processing are required. Every geoLOGr® project follows the same workflow. Hyperspectral data is processed using world-leading, cloud-based hyperspectral data processing methods that are customized for each project. Our in-house tools—anchored by the Lithotype™ Method—condense complex spectral information into reliable, actionable outputs, avoiding the low accuracy of common, industry-standard estimates.
Specialized outputs can include:
- Predictive dilution logs
- Predictive geochemical logs
- Deleterious mineral logs for risk management
- Predictive geometallurgical logs (e.g., hardness, grindability, density, floatability)
These tailored solutions give teams the flexibility to adapt to project-specific requirements without re-logging.

geoLOGr® FAQ
How is geoLOGr® different from hyperspectral imaging cameras and point-by-point systems?
The geoLOGr® combines advantages from both types of systems: it provides continuous data coverage with high spectral resolution and high data quality, while keeping data volumes manageable and costs reasonable. Strict QA/QC protocols are applied, and outputs are designed for rapid processing and easy output integration.
Which rock and deposit types can geoLOGr® analyze?
geoLOGr® can be used on any type of rock or deposit, including those formed from dark or low-reflective rocks. It’s built for all geological settings.
Does geoLOGr® provide “quantitative” mineral abundances?
No. Reflectance spectroscopy, in any form, is not a good method to gather quantitative mineral information. That should be left to other techniques, like XRD and QEMSCAN.
What sample types can geoLOGr® scan?
Whole drill core, cut drill core, RC chips, and blast samples. Acquisition is continuous and non-destructive, producing ~300 spectra per metre alongside 35 μm high-resolution line-scan imagery.
Is geoLOGr® a portable rock scanner?
Yes. The wheel-based, extendable frame and height-adjustable sensor head allow deployment on the floor, tabletop, or above a roller table—ideal for remote sites and tight core shacks.
How fast can we be operational and get results?
Teams typically become operational after ~1 day of remote training. Data are uploaded to our cloud processing pipeline, and decision-grade outputs are delivered in days, not months.
Are rentals available? Is data processing included?
The geoLOGr® is typically rented on a month-to-month basis, with all data processing included in the rental price.
How do outputs integrate with our software?
Outputs plug into existing logging, visualization, and modelling tools—such as Leapfrog and Imago—so your teams can adopt standardized logs without disrupting current workflows.
What about data volumes and QA/QC?
For about 300 meters of scanned drill core, the geoLOGr® produces about ~2 gigabytes in hyperspectral data and another ~10 gigabytes in drill core photos. Overall, these are very manageable data volumes that have been optimized for fast processing, storage, and archiving. All scans follow strict QA/QC to ensure the highest achievable data quality and consistent, reproducible results.
Can the geoLOGr® help with legacy core and multi-year programs?
Yes. The geoLOGr® supports drill core re-logging and legacy dataset integration, helping standardize across rigs, campaigns, and years while reducing re-logging and strengthening your models.
