Tembo Capital Management sold its 12.1 percent stake in Orion Minerals on 1 October 2026. The 1.08 billion shares were purchased by existing investors, including Tom Borman, who increased his stake to nearly 15 percent.
Why it matters
The divestment comes as the mining company seeks to secure significant capital for its Northern Cape projects. Orion Minerals currently requires up to R6.7 billion to fully fund its Prieska Copper-Zinc Mine and Okiep developments.
The transaction totaled A$20.55 million, representing a 16 percent discount to the closing share price. Orion Minerals has secured slightly less than R4 billion of its R6 billion to R6.7 billion funding requirement.
The players
Tembo Capital Management
This investment firm is based in the UK and has provided capital support to Orion Minerals since 2017.
Orion Minerals
The mining company is focused on the development of copper and zinc projects in the Northern Cape of South Africa.
Tom Borman
An investor who increased his stake in the mining firm to nearly 15 percent by purchasing half of the shares sold by Tembo.
Glencore
A multinational mining and commodities trading company involved in an offtake agreement for copper production.
Triple Flag
A precious metals streaming and royalty company based in North America that is currently negotiating project funding details.
The details
Tembo Capital Management exited its position as its investment fund reached maturity. Orion Minerals plans to bridge its remaining funding gap by utilizing early cash flow generated from the PCZM Uppers project.
Timeline
Tembo Capital Management began supporting Orion Minerals in 2017.
The Reserve Bank approved the copper offtake deal on 17 September 2026.
The share sale took place on 1 October 2026.
First production at the Prieska Copper-Zinc Mine is scheduled for Q3 2027.
Market Dynamics
The firm was added to the ASX all ordinaries index in late September, signalling growing institutional visibility. This sale reflects the standard lifecycle of private equity involvement as funds reach maturity and transition toward public market ownership.
Shareholders should note that the company shares have increased 27 percent over the last 12 months, despite the recent 16 percent discount applied to this block sale. The company's ability to reach production by 2027 remains the primary metric for long-term equity performance.
The takeaway
The exit of a foundational investor often signals a transition toward mainstream operational phases for development-stage miners. Investors should track the company's ability to cover its funding gap through production rather than relying on future equity placements.
