Maptek, a global leader in innovative mining technology, today announced the acquisition of PETRA, a pioneer in orebody learning and data fusion technology, marking a significant milestone in the evolution of mining decision‑support solutions.
Maptek has increased its shareholding in PETRA from 25 to 100 per cent, following a strategic partnership that began in 2019. The acquisition brings together two technology companies founded by mining professionals, united by a shared commitment to unlocking value through deeper orebody knowledge and geological variability.
Founded more than 40 years ago, Maptek develops integrated solutions that enable mining organisations to transform data into knowledge across every stage of the mining lifecycle. PETRA, established over a decade ago, is recognised globally for its advanced orebody learning software, which leverages data fusion, ore tracking and machine learning to deliver granular, high‑accuracy insights that optimise the mine‑to‑mill value chain.
“Maptek is invested with PETRA because their technology adds significant value to our customers’ data in ways that were truly first‑of‑their‑kind,” said Peter Johnson, Chairman of Maptek.
“PETRA invented digital mine to mill AI software, and they remain well ahead of the industry. By bringing PETRA fully into the Maptek group, we can support their continued innovation while delivering even greater value to our customers.”
Importantly, PETRA will continue to operate as a standalone business, retaining its strong brand, culture and technology‑agnostic approach. Dr Penny Stewart will remain as CEO, ensuring continuity for customers, partners and employees.
“Maptek and PETRA speak the same language,” said Penny Stewart, CEO of PETRA.
“We share the same fundamental purpose: using orebody knowledge to create value across the mine value chain. This acquisition allows PETRA to remain agile and independent, while benefiting from Maptek’s global network and corporate support.”
Both companies emphasised that their immediate focus remains on delivering innovation and value to customers. PETRA is progressing toward the release of MAXTA 6.0 in 2026, featuring advanced agentic AI designed to convert optimisation insights directly into measurable value for mining operations.
Integration opportunities between Maptek and PETRA technologies will be further explored in future phases. Maptek’s new Vestrex platform enables automation of data management, computation and workflows and decision support across the whole mining value chain and will enable customers to leverage the power of both companies’ solutions in ways not possible before.
With most mining technology providers now owned by equipment manufacturers or private equity, Maptek’s continued independence offers customers confidence, flexibility, and a long‑term focus on solving high‑value mining challenges.
Together, Maptek and PETRA aim to redefine how orebody intelligence is created, shared and applied across the mining industry.
Atrico acted as PETRA’s M&A advisor for the acquisition.
