Glencore Funding Paves Way for Prieska Construction

Orion Minerals (ASX:ORN) has taken a decisive leap towards production with a binding US$250 million prepayment facility agreement signed with Glencore plc, earmarked to fund the Uppers and Deeps developments at the Prieska Copper Zinc Mine (PCZM) in South Africa. This facility, linked to concentrate offtake agreements, represents a critical financial milestone as Orion transitions from explorer to base metals producer, targeting first copper and zinc output in 2027.

The funding is structured in two tranches: US$40 million to kickstart the Uppers construction and US$210 million to support the Deeps development, including an option for early drawdown. The deal includes market-related returns to Glencore, settled monthly and capitalised until about 18 months post first production from the Uppers. Orion retains the right to repay without penalty, with settlement via concentrate sales. Completion hinges on regulatory approvals and finalisation of linked offtake agreements, with expectations to clear conditions precedent by end Q2 2026.

This funding breakthrough follows earlier non-binding terms announced in September 2025 and builds on Orion’s strategic financing mix, including a convertible loan from the Industrial Development Corporation of South Africa (IDC) and a $A10 million early funding arrangement with Triple Flag. The IDC’s recent conversion of its ZAR250 million convertible loan into equity in Orion’s PCZM subsidiary further streamlines the capital structure and aligns interests among key stakeholders, simplifying arrangements for Glencore and other funders. This conversion, detailed in a prior announcement, gives IDC an effective 16.7% interest in PCZM and retains a shareholder loan of approximately ZAR272 million (~$23.3 million) IDC loan conversion into equity.

Operational Readiness and Value Engineering at Prieska

Behind the scenes, Orion’s Prieska team has been intensively focused on operational readiness, value engineering, and execution governance to optimise project delivery and shareholder value. The company has refined the mining schedule to delay Upper-Level mining start by six months, reducing risk around equipment procurement and workforce training. Mining at the Upper-Level will be contracted out to experienced firms, mitigating recruitment challenges.

Procurement is advancing with tenders for mechanised mining fleets evaluated on total cost of ownership, narrowing to three vendors for further discussions. Torque Africa has been appointed as preferred drilling contractor, pioneering a hybrid reverse-circulation and diamond core rig adapted for underground use; a first for South Africa expected to enhance drilling efficiency and cost control.

Orion is also reassessing tailings storage options, weighing underground paste fill against traditional surface facilities, and exploring potential to boost reserves by backfilling historical stopes to access previously excluded high-grade zones. Infrastructure planning includes staged electrical supply upgrades aligned with Eskom to meet the 70 MVA power demand, with the initial 35 MVA expected by month 16 and the balance by month 28, coinciding with Deeps mining commencement.

Okiep Copper Project Advances with Dewatering and Drilling

At the Okiep Copper Project (OCP), Orion has settled the final acquisition payment for a controlling interest, completing a key step in consolidating its Northern Cape portfolio. The company is actively progressing exploration and optimisation work, including a drilling program targeting near-surface inferred resources at the Flat Mines deposits to refine resource models and identify extensions.

Dewatering commenced at Flat Mine North following completion of a new wastewater dam, enabling access to underground resources. Metallurgical test work is underway to validate processing flowsheets for the Flat Mines South deposit, expanding beyond prior focus areas. Field mapping and geophysical surveys are planned to explore western tenements, following successful landowner negotiations.

Orion’s commitment to local communities continues through routine stakeholder engagement in the Nama Khoi region, alongside environmental management efforts maintaining compliance and zero incident records. The company’s acquisition settlement included cash and share payments, with ongoing exploration expenditure commitments to be met by November 2026 final acquisition payment for OCP.

Cash Position and Funding Outlook

Orion ended the March quarter with A$3.07 million in cash, reflecting ongoing cash outflows from exploration, corporate costs, and operational readiness activities. The company reported net cash used in operating activities of A$2.4 million and investing outflows of A$2.4 million for the quarter, partially offset by financing inflows of A$2.4 million. With less than one quarter of funding on hand, Orion is relying on the imminent completion of the Glencore prepayment facility conditions and continued support from major shareholders to maintain its development trajectory.

The company has a total loan facility of approximately A$40.3 million, including the IDC convertible loan and Triple Flag early funding arrangement, both fully drawn. Orion’s management expects to meet business objectives based on its track record of securing equity and debt funding, with the Glencore deal representing the cornerstone of its near-term financing strategy.

Bottom Line?

Orion’s US$250 million Glencore facility and IDC loan conversion mark critical financing milestones, but the company must swiftly satisfy conditions precedent to maintain its 2027 production target.

Questions in the middle?

  • Will Orion complete all regulatory approvals and conditions precedent for Glencore funding by end Q2 2026?
  • How will the IDC equity conversion affect Orion’s capital structure and future funding flexibility?
  • Can operational readiness and contractor appointments at Prieska keep pace with the revised mining schedule?
