BCI Minerals Earnings Call: Mardie Nears Final Stretch

BCI Minerals Ltd ((AU:BCI)) has held its Q2 earnings call. Read on for the main highlights of the call.

BCI Minerals’ latest earnings call carried a cautiously optimistic tone as management highlighted strong construction progress at Mardie, robust operating metrics in the brine ponds and a solid liquidity buffer. Risks remain around remaining construction packages, debt build‑up and softer near‑term salt markets, but management argued these are manageable against the project’s advanced status.

Construction advances with Mardie project 77% complete

BCI reported the Mardie project is 77% complete, with cumulative construction spend of about A$1.043 billion and total construction costs just over A$1.0 billion. Major earthworks for the salt wash plant, stockyard and non‑process infrastructure are largely finished, crystallizer seeding has begun and marine works at Port of Cape Preston West are roughly 94% complete.

Pond performance underpins target for first salt shipment

Operationally, the evaporation ponds ran at 96% utilization over more than 9,300 hours, with brine levels and densities across ponds 1–9 tracking closely to operational targets. The Poseidon digital model indicates pond 9 should reach target density in February, keeping the schedule for first salt on ship in the December 2026 quarter intact.

Liquidity buffer supports completion and ramp‑up

BCI ended the quarter with A$601 million of available liquidity, including A$351 million in uncommitted funds and estimates about A$400 million is needed to complete construction. Management stressed that this leaves the company fully funded not only to finish the build but also to cover working capital requirements during the early production ramp‑up.

Debt drawdowns rise as equity conversion trims borrowings

The company has now completed eight debt drawdowns totaling A$446.8 million, including A$99.8 million drawn in the latest quarter as construction spending continues. More than 50 million new shares were issued via conversion of a Series 1 convertible note, reducing borrowings by A$29.1 million but diluting existing shareholders in the process.

SOP pilot moves toward 140,000 tpa opportunity

BCI is advancing its sulphate of potash strategy, having commissioned KTMS trial crystallizers that are operating at steady state in line with expectations. The SOP pilot pathway targets around 140,000 tonnes per annum, with batch plant testing now complete and the pilot plant design award expected imminently, paving the way for future product diversification.

Scaling to multi‑million tonne salt producer

Once fully ramped, Mardie is expected to produce roughly 5.35–5.5 million tonnes per annum of salt, positioning BCI as a sizeable player in the global salt market. The Port of Cape Preston West is designed for about 20 million tonnes per annum of throughput, leaving some 14.5 million tonnes of surplus capacity that could be monetized through third‑party users.

Digital systems sharpen operational oversight

The company continues rolling out its Mardie operating system, including a mine production reporting system and a laboratory information management system to improve data quality. A digital twin known as “Poseidon” underpins brine modeling and pond management, helping operators make faster, data‑driven decisions and refine ramp‑up strategies.

Safety metrics and community investment remain in focus

Safety performance featured prominently, with more than 400 Leadership in the Field interactions and 290 critical control verifications completed, supporting a 12‑month rolling TRIFR of 3.9. Environmental monitoring of mangroves, turtles and shorebirds continues, while BCI formalized a two‑year A$480,000 capacity‑building program with the Wirrawandi Aboriginal Corporation.

Stepped activity drives lower near‑term spend

Construction activity eased in the December quarter as several large packages were completed, resulting in quarterly spend of just A$41 million. Management framed this as evidence of the stepped nature of remaining work, flagging that spend and progress may show timing variability as new packages mobilize.

Key remaining packages underscore execution risk

Critical tasks still ahead include dredging, remaining crystallizer lining and the salt wash plant, all of which must be delivered on time to protect the schedule. Dredging of the berth pocket and navigation channel is subject to final approvals and contracting and is expected to commence around April 2026, leaving some execution and timing risk on the critical path.

Higher leverage and dilution weigh on equity story

The A$99.8 million drawn from the syndicated facility this quarter added to BCI’s growing debt load as it moves through peak funding. While the convertible note conversion trimmed borrowings by A$29.1 million, the issuance of more than 50 million new shares introduces dilution, a trade‑off equity investors will need to weigh against the project’s progress.

Soft Chinese demand and Indian shift cloud near‑term market

Management noted softer short‑term demand in China, where some chlor‑alkali producers are feeling the impact of weaker real estate and domestic consumption. In India, export volumes declined from 28 million tonnes in 2024 to 26 million tonnes in 2025, a roughly 7.1% drop that highlights shifting domestic demand patterns and potential near‑term market volatility.

Third‑party port upside delayed by timing uncertainty

BCI sees strong strategic value in the surplus capacity at Port of Cape Preston West and has already attracted interest from potential third‑party users. However, management does not expect meaningful third‑party throughput in the next one to two years and says pricing and revenue structures are still to be worked through, pushing this upside further out.

Weather risks remain despite modeled buffers

Cyclone and heavy rainfall risk remains a reality for the March to May season, particularly for an evaporation‑pond‑based project like Mardie. While schedules and models incorporate historical cyclone scenarios and buffers, management cautioned that significant weather events could still disrupt brine density buildup and affect ramp‑up timing.

Guidance reinforces funding sufficiency and schedule confidence

BCI reiterated that Mardie is on track and fully funded to completion, with nearly A$1.3 billion invested to date including about A$255 million of pre‑revenue operating expenditure. Guidance calls for ponds to maintain high utilization, the first crystallizer cell coming online in February, salt wash plant commissioning by late October and first salt on ship in the December 2026 quarter as production ramps toward 5.35–5.5 million tonnes per year and SOP pilot work advances toward a 140,000 tpa pathway.

BCI’s earnings call painted the picture of a capital‑intensive project moving decisively into its final construction phases, backed by ample liquidity and improving operational data. For investors, the story now hinges on flawless execution of remaining packages, prudent debt management and how quickly global salt demand and potential port customers translate into cash returns once Mardie comes online.
