Gold mining is often imagined as a low-tech, brute-force industry. The reality in 2025 is strikingly different. From drone-based geological surveys to AI-assisted grade prediction and real-time process control, the modern gold mine is a technology-intensive environment where data drives decisions at every level of the operation.
At Eldoreydo Mining, we invest continuously in the tools and systems that sharpen our geological understanding, improve our operational efficiency, and reduce our environmental footprint. Here is a look at the key technologies underpinning our operations today.
1. 3D Geological Modelling
Understanding the shape, grade distribution, and continuity of a gold orebody is the foundation of every mining decision. Eldoreydo Mining uses industry-leading geological modelling platforms — including Leapfrog Geo and Micromine — to build dynamic, three-dimensional representations of our orebodies that are updated in real time as new drill data is generated.
These models allow our geologists and mine planners to visualise mineralisation with a level of precision and confidence that was simply not possible a decade ago. Mine design decisions — pit shell optimisation, stope layouts, cut-off grade selection — are made with reference to these models, reducing the risk of dilution and ensuring that ore and waste are correctly classified before any material is moved.
2. Drone and LiDAR Surveying
Traditional topographic surveying is time-consuming, expensive, and exposes personnel to hazardous terrain. Eldoreydo Mining has deployed UAV (unmanned aerial vehicle) photogrammetry and LiDAR scanning across our exploration and operating sites, delivering centimetre-accurate topographic data in a fraction of the time and at dramatically lower cost.
Applications include:
- Pit volume calculations and reconciliation against mining plans
- Stockpile volumetrics and grade management
- Structural mapping of rock faces to inform geotechnical risk assessment
- Progress monitoring of rehabilitation areas
Drone surveys that previously required weeks of field time can now be completed in hours, with data processed and delivered to the engineering team the same day.
3. Automated Fleet Management
In open-pit operations, haulage represents a significant proportion of total operating cost. Eldoreydo Mining deploys GPS-enabled fleet management systems across our haulage fleets, providing real-time visibility of truck position, payload weight, cycle time, and fuel consumption.
Automated dispatch systems use this data to optimise truck routing and loading sequences in real time, minimising empty kilometres, reducing queueing at the crusher and loading points, and maximising the utilisation of each unit of equipment. The result is a measurable reduction in haulage cost per tonne of ore delivered to the plant.
4. Process Automation and SCADA
Gold processing plants involve dozens of interdependent variables — grind size, pulp density, reagent dosing rates, leach residence times, carbon activity — all of which must be held within tight ranges to achieve optimal gold recovery. Manual control of these variables is inherently inconsistent.
Eldoreydo Mining operates fully instrumented processing plants with Supervisory Control and Data Acquisition (SCADA) systems and advanced process control (APC) loops that maintain plant stability automatically. Operators monitor dashboards in real time and intervene only when the system detects conditions outside pre-set parameters.
The benefits are tangible: tighter control of grind size consistently reduces energy consumption and improves liberation of gold particles, while stable reagent dosing reduces cyanide and lime consumption without compromising gold dissolution rates.
5. Online Elemental Analysers
Traditional laboratory assay turnaround — even at on-site laboratories — introduces a lag of several hours between a sample being taken and a grade result being available. In a high-throughput processing plant, that lag can mean tonnes of ore have been processed at non-optimal conditions before the problem is identified.
Eldoreydo Mining has installed online elemental analysers at key points in the processing circuit — including the crushed ore conveyor, the leach feed, and the CIL discharge. These systems provide continuous, real-time grade data that allows the process control team to make immediate adjustments to the circuit, protecting recovery and preventing gold losses.
Looking Ahead
The pace of technological change in the mining industry is accelerating. Eldoreydo Mining is actively evaluating a range of emerging technologies — including machine learning-based ore sorting, autonomous drilling systems, and hydrogen-powered haulage — for potential deployment at our operations over the next five years.
Our approach to technology adoption is disciplined: we pilot new systems thoroughly before committing to full-scale deployment, and we measure the performance of every technology investment against clear, quantified targets for cost, recovery, and environmental impact.
Conclusion
Technology is not a luxury in modern gold mining — it is a competitive necessity. The companies that invest in geological intelligence, operational automation, and process optimisation will consistently outperform those that do not, across all stages of the commodity cycle.
At Eldoreydo Mining, we are committed to staying at the forefront of mining technology — not for its own sake, but because better technology means more gold recovered, more efficiently, with less impact on the environment. That combination is good for our investors, good for the communities we work in, and good for the long-term future of our business.
