Understanding the Earth.Informing better decisions.
Geoscience, engineering, environmental intelligence and advanced geospatial technologies for complex projects across Latin America.
We study the Earth from multiple perspectives.
Brato integrates geology, engineering, water, geomorphology, environmental science and geospatial technologies to transform complex territorial information into actionable technical intelligence.
Geology
Mapping, structure and lithology carried from the field into a model that a decision can rest on. Twelve geological models built to date, across coal, gold, emerald and industrial minerals.
- Geological mapping
- Structural geology
- Lithological characterization
- Mineral exploration
- 3D geological modeling
- Resource and reserve estimation
- Sampling design and QA/QC
- Reporting under the ECRR
Engineering
Rock and ground behaviour, from a highwall to an underground drift. Ten geomechanical studies delivered, including ventilation design for working mines.
- Rock mass characterization
- Slope and pit stability
- Underground ground support
- Subsidence assessment
- Foundation conditions
- Geotechnical modeling
- Mine ventilation planning
- Instrumentation and monitoring
Water
Surface and subsurface water treated as one system, because a mine, a road and a licence all fail on the same misunderstanding of it.
- Watershed and drainage analysis
- Runoff and flood analysis
- Water balance
- Aquifer characterization
- Groundwater assessment
- Pumping tests
- Water well siting and design
- Monitoring networks
Environment
Abiotic baseline work for environmental licensing. Six filings delivered before the national environmental authority.
- Abiotic baseline studies
- Vegetation cover analysis
- Land-use analysis
- Environmental monitoring
- Erosion assessment
- Licence applications and modifications
- Change detection
- Territorial analysis
Geospatial
Sensors and GIS as an extension of field observation, not a replacement for it. Every dataset is validated against ground truth before it enters a model.
- UAV survey with RTK
- Orthophoto and orthomosaics
- Airborne and UAV LiDAR
- Underground laser scanning
- Point cloud classification
- Digital terrain and surface models
- Satellite and multispectral analysis
- Spatial databases and cartography
Risk
Where the ground moves, where the water goes, and what it reaches. Hazard work for operators, asset owners and municipalities.
- Landslide susceptibility
- Slope instability
- Subsidence over old workings
- Flood risk
- Erosion assessment
- Geological hazard mapping
- Terrain susceptibility
- Monitoring recommendations
From territory to intelligence.
Capture begins in the field, where geological, engineering, environmental and territorial observations are collected by people who have to walk the ground.
LiDAR, UAVs, GNSS, laser scanners and remote sensing expand the scale and precision of observation, including into workings no one can safely enter.
GIS, point clouds, orthophotos, terrain models and geological datasets create a structured digital representation of the territory.
Observations become geological, terrain, hydrological, hydrogeological and engineering models, with every assumption written down.
Spatial analysis, geostatistics, remote sensing and engineering interpretation turn the model into an answer with a stated confidence.
Technical intelligence becomes a decision someone can defend: to drill, to build, to license, to finance, or to walk away.
Eight disciplines. One investigation.
Geology
Mapping, structure and lithology, carried from outcrop and underground exposure into a coherent model.
→Mineral Resources
Estimation and classification under the ECRR, Colombia's standard within the CRIRSCO family.
→Geotechnical
Rock mass characterization, slope and underground stability, subsidence and ground support.
→Hydrology
Watershed, drainage, runoff and flood analysis, and the water balance behind them.
→Hydrogeology
Aquifer characterization, groundwater assessment, well siting and pumping tests.
→Geomatics & GIS
UAV survey, LiDAR at surface and underground, point clouds, terrain models and spatial analysis.
→Environment & Territory
Abiotic baseline studies for environmental licensing, land cover and territorial change.
→Risk & Geomorphology
Landform analysis, susceptibility mapping and geological hazard assessment.
→Seeing change across the landscape.
Remote sensing, GIS, field observation and spatial analysis characterize vegetation cover, land use, environmental conditions and territorial change. Technical projects exist within real territories and the communities connected to them, and good decisions require understanding both.
Earth. People. Territory.
Let's understand the territory.
Tell us about your project.
Field first.
Data driven.
Brato Mineral Resources brings together Earth science, engineering and digital technologies to understand complex environments and support better technical decisions.
Resource reporting follows the ECRR, Colombia's national standard within the CRIRSCO family, and the mining authority's good practice guides. Because the ECRR shares the CRIRSCO definitions and classification framework, the same work carries across to JORC, NI 43-101 and SEC Regulation S-K subpart 1300 without being rebuilt.
Estimation is reproducible: raw data, database validation, QA/QC of sampling with certified reference material, blanks and field duplicates, laboratory performance monitoring, geostatistics where the data supports it, block model, and a written statement of every assumption behind the modifying factors. Modelling in Vulcan and Surpac; spatial work in ArcGIS Pro and QGIS; survey by RTK drone and LiDAR at surface and underground.
Where a report is issued under JORC, NI 43-101 or S-K 1300, Brato prepares and delivers the technical work and the report is signed by a Competent or Qualified Person registered with a recognised professional organisation. We state that on the face of the document rather than leaving it to be discovered.
Specialist services — exploration and water well drilling, laboratory analysis, ground geophysics, airborne magnetics, radiometrics, gravimetry and LiDAR — are delivered by associated providers under our specification and supervision. They are named in the proposal, not discovered in the invoice.
Brato maintains an anti-money-laundering and counter-terrorist-financing programme, a compliance manual and a code of ethics, and screens counterparties before accepting an engagement.
We do not evaluate an asset we prepared, and we do not prepare an asset we have evaluated.
The people who sign.
Reports are signed by the professional who did the work, named, with their registration number and scope of responsibility stated on the face of the document.

The Earth as data.
Field → sensors → data → modeling → analysis → decision. Technology is not the product. It is what makes the geology defensible at a scale a person cannot walk.
Where Colombia actually sits.
In November 2025 the United States expanded its List of Critical Minerals from 50 commodities to 60, adding boron, copper, lead, metallurgical coal, phosphate, potash, rhenium, silicon, silver and uranium. Colombia keeps its own list of strategic minerals. Fifteen commodities appear on both.
Gold is absent from the US list, and its absence is worth explaining. Gold is not supply-constrained the way a critical mineral is, and it does not need to be: it is the commodity that actually funds mining in Colombia. Gold-silver veins in the Colombian Andes carry silver, lead and zinc, three commodities that are on the US list, and the structural work that defines one defines the others.
Copper sits on both lists. Colombia sits on the same Andean belt as Chile and Peru, and has a fraction of the drilling.
We specify it. Specialists execute it.
A consultancy is not paid for owning a drill rig. It is paid for specifying the right programme, choosing a contractor who can deliver it, supervising the work, and validating the data before it enters a model that someone will make a decision on.
Exploration drilling
Programme design, collar and downhole survey control, logging, core handling, recovery and RQD control.
Water well drilling
Siting from hydrogeological interpretation, well design, pumping tests, aquifer parameters and safe yield.
Laboratory analysis
Lab selection and qualification, chain of custody, CRM, blanks and duplicates, umpire lab checks.
Ground geophysics
Magnetics, IP and resistivity, electrical resistivity tomography, seismic refraction, GPR.
Airborne surveys
Magnetics, radiometrics, gravimetry and LiDAR. Flight specification, contractor selection and data acceptance.
LiDAR scanning
Surface and underground. Workings and void inventory, stope survey, highwall monitoring, point clouds.
Selected project experience.
Delivered work. Client names are withheld unless the client has authorised disclosure, which is why these are described by commodity, setting and scope rather than by company.
Geoscience across Latin America.
Regional expertise and project capabilities. Field operations are based in Colombia; in Ecuador and Venezuela we work with locally registered counterparts.
Insights.
Short pieces on what is changing in Colombian mining regulation, reporting standards and critical minerals policy, and what it means for the people who have to act on it.
