Infrastructure-led Bitcoin mining.

We participate in Bitcoin mining as an active operator. Hardware, thermals, pool management, fault response — managed from the ground up at Green Data City, Oman.

Green Data City

Green Data City is a digital infrastructure and colocation environment focused on modular Bitcoin mining. STM is a client on the site: we have invested in and operate our own containerised mining deployment within Green Data City, alongside other operators.

This is not a passive investment. The operation includes 220 Bitmain Antminer S19j Pro+ units — roughly 26–27 PH/s of nameplate hashrate — with power demand in the one-megawatt class once mining load, cooling, and supporting infrastructure are included. STM is involved in hardware selection, site setup, operational monitoring, and maintenance.

Our operational role

Site & infrastructure management — containerised mining units installed and maintained on-site
Hardware operations — ASIC miner deployment, performance monitoring, fault response
Thermal & power management — cooling systems and power infrastructure oversight
Pool & hashrate management — pool selection, optimisation, and performance tracking
Deployment economics — we own and manage our mining capacity and equipment on site

Infrastructure partnerships. Organisations interested in digital infrastructure partnerships, mining co-location, or related investment discussions are welcome to reach out via our contact page.

Our approach

Engineering first. Always.

We treat mining as an engineering operation, not a financial speculation. Hardware uptime, temperature efficiency, and cost per terahash are the metrics that matter — not price predictions.

Hardware-first

Every unit selected, installed, and monitored by our own team.

Thermal discipline

Cooling infrastructure managed with the same rigour as compute.

Cost per terahash

Operational efficiency — not speculation — drives our decisions.
