Overview

Gemtoll SA (Pty) Ltd was established in 2020.
Established by a group of innovative mining technology specialists together with minerals and commodity traders who invested a lot of time in researching a greener way of upgrading ores and minerals to high grade concentrates and metals using environmentally clean methods. We are driven to make improvements in eliminating the harmful traditional leeching technologies used in metals and mineral extraction and our mission is to invest in environmental and sustainable projects for the betterment of all.
At Gemtoll SA together with our technical partner Trip 7 Resources, we possess a comprehensive range of capabilities and operations encompassing research & development, project management and innovation throughout the minerals value chain. Our services encompass mineral processing, production of metal-based products, process development, and post-mining support. Our processing solutions can be implemented in any remote region and require very limited technical training to operate.
We follow a focused approach that emphasizes scientific excellence and technological breakthroughs, establishing clear connections to real-world industry applications. We consistently strive to push the boundaries of what is achievable.
Our Core Values
At Gemtoll SA, we are guided by a steadfast commitment to innovation, environmental stewardship, and integrity. We believe in harnessing science and technology to create sustainable mineral solutions that uplift communities, respect the planet, and redefine industry standards. Collaboration, transparency, and responsible sourcing form the backbone of our operations — ensuring that every breakthrough we achieve contributes meaningfully to a cleaner, more equitable future.
Our Mission
We aim to lead innovation in mineral technology in Africa, transforming minerals to transform lives, and catalysing opportunities in our rich mineral-based African economy.
Our Vision
Our Vision is to become a global leader in clean carbon neutral minerals extraction and processing solutions.
The Future
Gemtoll SA CEO, Howard Butler firmly believes that over the next 3 years we will transform the way battery minerals are upgraded in the future and set the platform for other EV battery manufacturers to set up shop nearby in the Industrial Development Zone (IDZ).
Battery storage system assembly plants could also tap into and feed off the high-quality products which Gemtoll SA can supply rather than importing from Europe, Asia and the US.
Other plans further along shall focus predominantly on copper, gold and antimony but will capture other minerals such as nickel, manganese and cobalt found in the copper ores. Based on extensive trials, we should be able to upgrade the copper from 4% up to a 60% concentrate.
All plants will be 100% environmentally friendly using non-toxic chemicals in the process.

Frequently Asked Questions
-
What makes Gemtoll SA’s mineral processing technology different from traditional methods?
Unlike conventional mineral processing that relies on toxic chemicals and energy-heavy infrastructure, our technology uses clean, non-toxic methods such as ultrasonic resonance. This allows us to extract and upgrade minerals with minimal environmental impact — even in remote regions.
-
Which minerals does Gemtoll currently focus on?
Our primary focus includes lithium, antimony, copper, gold, and various critical minerals such as cobalt, nickel, and manganese. We also have proven extraction techniques for PGM’s and rare earths using our proprietary tech.
-
Is Gemtoll’s technology already in use?
Yes. Apart from other NDA protected projects, we currently operate a 2-ton-per-hour antimony pilot plant in Johannesburg and are preparing to launch large-scale lithium extraction facilities in Zimbabwe and Botswana. Our systems have been validated and are ready for scaled deployment.
-
How is Gemtoll contributing to sustainability in mining?
We eliminate toxic leaching agents and reduce energy usage through innovative processing techniques. Our modular plants can operate off-grid, are safe to run, and minimize environmental disruption — helping mining evolve into a cleaner, more responsible industry.
-
Can your processing plants operate in remote or off-grid locations?
Absolutely. One of the key advantages of our systems is their portability and ease of deployment. They require minimal technical training and can be operated in remote areas without access to national infrastructure.
