In 2013, deep in Mongolia’s rugged Bayankhongor Province, Gekko Systems delivered a project that would become a defining chapter in our 30‑year journey: a fully modular gravity plant for REO LLC, the country’s only underground gold mining company.
This installation demonstrated Gekko’s technical capability and showcased the ingenuity, speed, and resilience that have shaped Gekko’s identity since day one.
REO’s Khuush Mine presented a unique challenge: a high‑grade alluvial deposit in one of the coldest mining regions on earth. Traditional plant construction would have taken far too long and struggled to withstand the extreme winter conditions.
The plant, featuring an InLine Pressure Jig (IPJ2400), a cleaner IPJ1500, two InLine Spinners (ISP30), and a fully equipped gold room, was delivered and commissioned in a fraction of the time required for conventional builds. Our Technical Services Team completed commissioning early in 2013, enabling REO to accelerate production and reduce operational risk.

2013: The modular plant that helped Mongolia’s only underground gold mine operate year‑round
What made this installation truly remarkable was the surrounding infrastructure:
- A fully heated building enclosing the entire plant
- Heated process water storage to prevent freezing
- A design that enabled year‑round operation, even in sub‑zero temperatures
It was a complete operational ecosystem built for resilience.
REO’s spokesperson, Ganbat Tseveenregzen, captured the spirit of the collaboration:
“Gekko was chosen simply because we wanted to buy the best gravity gold plant available.”
For Gekko, this project marked more than a successful installation. It represented the global confidence placed in our modular philosophy, and the trust in our Australian-manufactured equipment that has propelled our growth from Ballarat to Johannesburg, Toronto, Accra, and beyond.
As we celebrate 30 years of innovation, the REO Mongolia project stands as a testament to what defines Gekko Systems:
- Modularity that accelerates manufacturing and installation timelines
- Energy‑efficient, low‑footprint design
- Solutions engineered for real‑world conditions
- Partnerships built on trust, performance, and shared ambition
Three decades on, we continue to push boundaries in gravity separation, pre‑concentration, and digital optimisation, always with the same spirit that delivered a fully operational plant to one of the coldest mining regions on the planet.
This milestone reminds us that innovation is not just about technology. It is about being innovative, working collaboratively, and the belief that better ways are always possible.
