Start free 14-day trialWhat a mining tech investor backs
A mining tech investor backs startups that modernize mines. In South Africa that means safety, automation, and ESG.
Most back deep-tech founders with a working pilot. Founders pitching Johannesburg AI investors face a similar bar.
They want proven ROI at a real mine, not just a lab. Keep all your pilot data in one clean data room.
Ellty gives each fund one trackable link and logs every open. You see who studied your pilot data before the call.
Only a united, forward-looking industry can embrace innovation, secure investment, and build a resilient, inclusive future.

Safety and automation underground
Deep South African mines are among the world's most dangerous. New tech is now making these deep mines much safer.
Sensors, drones, and automation cut risk underground. Investors fund tech with clear, proven safety gains.
Funds check your ROI and your safety record closely. Track every reader with built-in document analytics.
Run commercial due diligence on your market early. It shows these funds you understand the mining sector.
ESG and the green transition
Mines face hard pressure to cut carbon and water use. That drives strong demand for greener mining tech.
Tailings, water, and energy tech pull in real money. Anglo and Sibanye fund a large share of that work.
Investors want a real ESG case backed by hard data. Keep all that sensitive data behind strong security.
Run environmental due diligence on your tech early. It maps closely to what mining funds expect now.
From pilot to mine-wide rollout
Most minetech starts with a single test-mine pilot. The hard part is reaching a full mine-wide rollout.
Investors want proof your pilot becomes a contract. Mining majors move slowly, but they pay very well.
Bigger rollouts often need private equity and finance. Clean and clear data builds their trust quite fast.
Send mines and funds clean pilot and ROI updates. Ellty shows you exactly who reads each update sent.
