Welcome to the New Era
of Diamond Mining

SETEH is a team of dedicated professionals who have been engaged in diamond mining since 2007. Having started with traditional methods of gravel extraction, we eventually encountered technological limitations — and decided to create our own patented dredging system.

Our Journey FROM CONCEPT TO TECHNOLOGY

ZPG-1 (Floating Grab Dredger)

2014–2016: Designed and built in Ukraine.
2017: Sent for testing in the Democratic Republic of Congo under the supervision of Bureau Veritas.
Result: The method’s functionality and efficiency were confirmed. The technology was patented.

What Makes Our Technology Unique

Diamonds possess exceptionally high specific gravity and are found at the deepest layers of the riverbed.

In the region's river systems - narrow but extremely deep (up to 200 meters) - traditional mining methods are nearly impossible to implement.

Diamonds migrate from kimberlite pipes (Angola) and settle in deep pockets at the bottom of the river.

At the core of SETEH’s concept is mining where no one else can reach.

FURTHER STEPS: IMPROVEMENT & MODIFICATION

Designed following the successful ZPG-1 trials.
Fully assembled and launched in Congo.
High functionality and superior performance.

ZPG-2 Advantages

Access to diamond-bearing gravel from depths of up to 100 meters.
Fully autonomous: requires no fuel or electricity (powered by the river’s kinetic energy).
Operates in extreme conditions — day and night.
Silent and environmentally friendly extraction.
Requires only 3 crew members: a winch operator and two workers on the vibration sorting table.

Scope of Work

Extraction of diamond-rich gravel using the patented ZPG-2 dredger and unique mining method.

Full-cycle dredger production -from design to serial manufacturing.

Operations with specialized equipment for efficient land-based diamond extraction.

To extend beyond traditional underwater mining, SETEH has introduced advanced machinery tailored for land-based extraction. This strategic expansion allows the company to access diamond-rich gravel deposits in dry terrains, ensuring year-round productivity and diversifying operational capabilities.
Operating in remote regions with complex geology, our equipment is designed for mobility, fuel-efficiency, and minimal environmental impact. The land-based systems complement our patented ZPG-2 dredger, enabling parallel operations both onshore and in riverbeds.
This dual-extraction approach not only increases yield potential but also enhances logistical flexibility, allowing rapid deployment in areas where water-based mining is limited or seasonal.
