About Kantra

Kantra Copper (ASX:KAN) is a growing ASX-listed Australian copper producer with its heart in South Australia. Kantra has operated since 2005 and completed open-pit mining at Kanmantoo in 2020. In 2023 we commenced development of our underground mine and in 2024 completed our transition to underground copper production.

Our operation is well capitalised with a 3–3.6Mtpa processing plant, with permitted surface infrastructure in place. Kantra is also testing the next suite of high-potential targets. In addition to the Kanmantoo operation, we have a large land holding of granted Exploration Licences in South-eastern South Australia, which are highly prospective for the discovery of economic copper deposits within a variety of geological settings (“Southeastern Copper Project”).

Kantra supplies critical minerals for a sustainable future, backed by long-standing environmental stewardship and strong stakeholder relationships. With a well-understood ore body and proven metallurgy, we deliver stable performance, deep regional know-how, and active participation in South Australia’s mining community.
