A collective of mining operations, owned and run by the who work them.
A mining collective, run by .
GTA Metals Mining Group is a collective of mining operations across South America. It is owned and run by highly experienced mining engineers — people who have spent their working lives getting material out of the ground and into specification, rather than trading it at a distance.
The group currently works copper, iron ore, manganese and lithium. Processing is handled at the operation wherever the material allows it — crushing, conveying, screening and sizing on the same ground the material came out of — so what leaves is already graded rather than shipped raw for someone else to sort.
Iron ore is the group's established line and carries the most detail; copper, manganese and lithium are supplied against enquiry. Grades, volumes and commercial terms are set operation by operation — each material's own page carries what is confirmed for it.

Iron ore is the group's established line, extracted and sized at the operation it comes from. Copper, manganese and lithium sit alongside it.
Every material. One .
Iron ore leads the line, in raw run-of-mine and granulated form. Copper, manganese and lithium are offered on enquiry, with specifications confirmed per operation.
From the working face to .
Across the collective, material is extracted and processed on the same ground, then graded and sized before it moves.
Extraction
Each operation works its own ground. Areas, extraction rates and grades are stated per operation and per material rather than averaged across the group.
Primary crushing
Run-of-mine material takes its first size reduction on site, straight off the pit, rather than being hauled away raw.
Secondary crushing
Secondary lines work alongside the primary, so throughput is not held up by a single crusher.
Conveying, screening & sizing
Inclined conveyors feed screen decks and sized product bins, taking crushed material through to a graded, sized product.
Supply to buyers
Material is supplied raw or graded, depending on the line and what the buyer needs. Sizing and volumes are confirmed against each enquiry.
Areas & partnerships
The collective takes on new ground and new partners where the engineering case holds up. See acquisitions →
Ore at the .
The collective works its own ground. Material is crushed, screened and sized where it comes out, so what leaves is already to size and to grade rather than someone else's problem to sort.
How the collective .
Every operation follows the same path from working face to graded product. The plant, the rates and the sizing differ by material — each one is set out on its own page.
Working the ground
Material is worked from the operation's own ground. Areas, rates and grades are stated per operation.
Run-of-mine material
Material leaves the face as run-of-mine. Part of it is supplied raw; the rest goes forward to the crushing lines.
Crushing on site
Feed hoppers and crushing lines take the size reduction at the operation, rather than hauling raw material away to be processed elsewhere.
Screening & sizing
Inclined conveyors feed screen decks that split the crushed material into size fractions.
Graded product
Sized material drops into product bins, graded and ready to move under the terms agreed for each contract.
Sized, binned and ready to .
Raw and graded material leaves the operation under the route and terms agreed for each contract.
The people behind the .
GTA is owned and run by its engineers. Between them the partners carry decades in metallurgical and fluid engineering, and they hold the operating and commercial responsibility for the collective.
