Minbos moves Cabinda plant towards Q2 2027 commissioning

Mining By Maxwell Dee 4 min read

Minbos Resources spent A$4.7 million on plant and equipment as construction advanced at its Cabinda phosphate project in Angola. The company also completed a post-quarter A$6 million placement, but BFA funding and approvals remain key dependencies for its Q2 2027 commissioning target.

  • A$4.712 million spent on property, plant and equipment during the quarter
  • Subantando plant construction and equipment shipments progressed
  • A$6.0 million placement completed after quarter end at A$0.015 per share
  • A$5.274 million cash held at 30 September, with A$16.186 million in undrawn facilities
  • Q2 2027 completion and dry commissioning target remains subject to funding, deliveries and approvals

Cabinda construction moves into equipment installation

Minbos Resources Limited (ASX:MNB) has moved its Cabinda Phosphate Project further into construction, with A$4.712 million spent on property, plant and equipment during the September quarter and heavy earthmoving activity beginning at the Cacata mine site. The company is targeting completion and dry commissioning of the Subantando fertiliser plant in the second quarter of 2027, although that timetable remains conditional on financing, equipment deliveries and regulatory approvals.

Phase 2 construction began during the quarter after independent technical adviser Stelo completed a Subantando site visit and approved relevant funding conditions precedent. Structural steelwork left Portugal on 26 August, construction crews reached Cabinda in early September, and equipment and materials continued moving through the Port of Cabinda. The company said a drying drum had been placed at the plant as installation work progressed.

Mine preparation and contractor work gather pace

At Cacata, Minbos continued work on its Phase 1 Mine Plan, mining tender assessment, haulage strategy and site infrastructure. The company has since appointed CABMINAS for earthmoving, site preparation and ore-haulage services, giving the mining side of the project a named operating partner as plant construction advances.

The quarter’s progress builds on the BFA financing and construction update, which reported that the FGC guarantee process had been finalised for an initial proposed BFA drawdown and that steelwork for Phase 2 had begun shipping from Portugal. In the latest report, however, Minbos described securing the guarantee and funding drawdown as immediate priorities rather than completed milestones.

A$6 million placement strengthens near-term funding

Minbos ended September with A$5.274 million in cash and cash equivalents. Net operating cash outflow was A$1.662 million for the quarter, while investing outflows were dominated by plant and equipment spending. The company also reported A$16.186 million in unused financing facilities, producing disclosed total available funding of A$21.460 million and an estimated 12.9 quarters of funding at the quarter’s relevant expenditure rate.

That calculation includes undrawn facilities rather than cash alone. Minbos subsequently completed an upsized A$6.0 million placement at A$0.015 a share after shareholder approval, following the A$6 million placement expansion. The raise improves the immediate funding position, but the company is still pursuing the proposed BFA-backed financing and an initial drawdown of approximately US$1.3 million to support payments to key suppliers.

Funding and approvals remain on the critical path

The existing IDC loan facility has a total reported value of A$23.122 million, with A$6.936 million drawn at quarter end and A$16.186 million undrawn. The facility is denominated at US$16 million, carries interest at SOFR plus 8.26%, runs for seven years from its first drawdown on 10 June 2026, and is secured against project assets and subsidiary shares.

Minbos continued discussions with the Fundo de Garantia de Crédito, Banco de Fomento Angola, Angolan financial institutions and other potential funding partners. It also maintained engagement with Angola’s Ministry of Mineral Resources, Petroleum and Gas, while progressing domestic fertiliser demonstrations, customer discussions and potential export-market opportunities. Those activities provide commercial and regulatory workstreams alongside the physical build, but the filing does not remove the financing and approval conditions attached to the 2027 target.

Next milestones shift from design to execution

The next evidence points are practical ones: confirmation of the FGC guarantee and BFA drawdown, continued equipment installation at Subantando, and mobilisation of earthmoving and haulage services at Cacata. Minbos must also convert its mine planning and customer engagement into an operating sequence capable of supporting the plant’s intended commissioning timetable.

Bottom Line?

The project is visibly moving from fabrication towards execution, but Q2 2027 commissioning still depends on turning proposed BFA support, deliveries and approvals into completed milestones.

Questions in the middle?

  • When will the FGC guarantee and approximately US$1.3 million BFA drawdown be formally completed?
  • Can equipment installation and Cacata mobilisation stay aligned with the Q2 2027 dry commissioning target?
  • How much of the A$6 million placement will be absorbed by construction, mining mobilisation and working capital before first production?
