Mineral Exploration
We identify the potential of Brazilian subsoil before anyone else.
Texas Holding has its own technical capability to identify, assess and develop areas with mineral potential across Brazil. That capability is delivered through its subsidiary Tobias Geotecnologia, a mineral research specialist with more than 25 years of work and hundreds of projects across the country.
Method
Classic field methodologies combined with indirect prospecting.
Tobias Geotecnologia combines classic field geology methodologies with advanced indirect prospecting technologies, reducing cost and time in identifying mineral targets.
Airborne geophysics
Magnetometry and gamma spectrometry surveys that map geological structures in the subsurface without touching the ground.
Multispectral remote sensing
Sentinel-2 satellite imagery (European Space Agency) that identifies mineralogical alterations at surface level from space.
Artificial intelligence
Trained models that cross geophysical, spectral and geological data to rank the areas with the highest probability of mineralisation.
Field validation
Geological mapping, systematic sampling and drilling to confirm and qualify the targets identified remotely.
From the field
How the ore presents itself in nature.
Field records from a Texas Mineração area in Pará. This is how copper and gold appear in the rock, before any processing.

International-standard methodology
Data auditable by Qualified Persons.
Tobias runs its field campaigns following sampling, quality control (QA/QC), documentation and chain-of-custody protocols compatible with Canada's NI 43-101 standard and the Australian JORC code — the leading international standards for mineral resource reporting.
This means the data collected can be audited and validated by internationally accredited Qualified Persons (QP) without repeating the field work.
