Metals X reported its fourth highest quarterly tin production at Renison with robust financials despite rising unit costs, while progressing the Rentails project and maintaining a strong cash position.
- Renison delivers 2,887 tonnes tin-in-concentrate
- Imputed EBITDA rises 8.77% to A$122.39 million
- Unit costs increase due to lower grades and operational issues
- Rentails FEED awarded, environmental approvals underway
- Strong cash balance of A$359 million supports growth
Renison Hits Fourth Highest Quarterly Tin Production
Metals X Limited (ASX:MLX) posted solid tin production of 2,887 tonnes of tin-in-concentrate for the March 2026 quarter at its Renison Tin Operation in Tasmania. This figure, while down 13% from the record 3,319 tonnes in Q4 2025, still ranks as the fourth highest quarterly output on record. Metals X’s 50% share was 1,444 tonnes.
The dip in production largely reflects a transition away from exceptionally high-grade stopes mined in the prior quarter, with the ore grade falling from 2.34% tin to 1.63%. Despite this, the operation maintained strong mill throughput and metal recovery, overcoming equipment breakdowns and wet ore challenges that affected plant availability. This resilience underpinned a lift in imputed EBITDA by 8.77% to A$122.39 million on a 100% basis, driven by a higher average tin price of A$69,726 per tonne, up from A$58,086 in the previous quarter.
Unit operating costs, however, rose noticeably. C1 cash production costs increased to A$18,653 per tonne of tin-in-concentrate, up from A$16,598, while all-in sustaining costs (AISC) climbed to A$32,567 per tonne. The all-in cost (AIC) rose to A$34,707 per tonne, reflecting the combined effect of steady total costs spread over fewer tonnes produced. These cost pressures highlight the operational challenges faced during the quarter despite the strong price environment.
Rentails Project Progresses with FEED Award and Regulatory Steps
On the development front, Metals X continues to advance the Rentails Project, a key growth initiative within the Bluestone Mines Tasmania Joint Venture (BMTJV). The front-end engineering and design (FEED) contract for the Rentails Concentrator was awarded to GR Engineering Services Limited, covering design work for a new tailings reprocessing facility with a 2.4 million tonnes per annum capacity. The FEED package remains on track for completion late in 2026, setting the stage for a final investment decision.
Environmental approvals are progressing in parallel, with the Environmental Impact Statement submitted to the EPA Tasmania and the Public Environmental Report lodged with Commonwealth authorities. These regulatory milestones are critical for the project’s advancement and underline Metals X’s commitment to sustainable development.
Capital Investment Focuses on Mine Dewatering and Underground Upgrades
Capital expenditure for the quarter totalled A$19.05 million, consistent with the prior quarter. Key investments targeted mine dewatering infrastructure, including pump station electrical installations and underground dam construction, as well as underground projects such as the winder control system upgrade and power factor correction system, both facing shipping delays. The commissioning of Mill Pond Tank #2 and successful installation of high voltage switchgear marked important site improvements.
These projects aim to sustain production capacity and improve operational efficiency, supporting Renison’s near-term output while positioning the mine for longer-term resilience.
Exploration and Resource Drilling Advance Across Multiple Targets
Exploration efforts continued with 14,473 metres of underground drilling and 2,864 metres of surface resource development drilling completed during the quarter. Drilling targeted resource definition and grade control across the Ring River, Ringrose, and South Basset areas. Surface exploration included a 1,211-metre program with promising preliminary results from electromagnetic surveys, which will guide future drill targeting.
This sustained drilling activity supports the company’s strategy to extend the mine life and identify new ore zones, complementing the existing reserve base confirmed in recent years. The ongoing soil sampling and geophysical surveys indicate a methodical approach to resource expansion.
Robust Financial Position and Strategic Investments
Metals X closed the quarter with a record cash balance of A$359.08 million, bolstered by strong operating cash flows and the realisation of tin inventory and receivables. Imputed net cash flow increased by nearly 10% to A$101.10 million on a 100% basis. The company also received a semi-annual interest payment from its convertible notes in Cyprium Metals Limited (ASX:CYM).
Strategic investments remain a key pillar of Metals X’s portfolio. The company holds significant stakes in First Tin Plc, Elementos Limited, Greentech Technology International Limited, Nico Resources Limited, and Tanami Gold NL. Notably, Greentech’s recent HKEX listing cancellation and subsequent review request introduce uncertainty around that investment’s outlook.
Metals X’s continued investment in these entities provides exposure to complementary tin and base metal projects, aligning with its growth-by-acquisition strategy and operational expertise. The company’s cash reserves and investment income provide flexibility to pursue further opportunities.
Safety Improvements and Environmental Commitments
Safety performance at Renison improved, with the Lost Time Incident Frequency Rate falling to 1.7 and Total Recordable Injury Frequency Rate decreasing to 5.1. The site implemented initiatives such as hazard awareness training and the Blue Shirt Project to support mental health, reflecting a proactive approach to workforce wellbeing.
Closure activities at the Mt Bischoff mine remain on schedule, with positive regulator feedback received. The submission of the Mine Closure Plan is anticipated mid-2026, demonstrating Metals X’s commitment to responsible environmental management.
These ESG efforts complement the company’s operational progress and underpin its social licence to operate.
Metals X’s Q1 performance builds on a string of strong quarters, including a recent 30% revenue surge and near-record production in Q4 2025 that doubled EBITDA. The Rentails project remains a focal point, with the FEED completion and environmental approvals setting the stage for a critical investment decision later this year.
Bottom Line?
Metals X’s solid operational and financial performance masks rising unit costs and project execution risks, making the upcoming Rentails feasibility and regulatory milestones pivotal.
Questions in the middle?
- How will Metals X manage rising unit costs amid fluctuating ore grades and operational challenges?
- What impact will Greentech’s HKEX listing uncertainty have on Metals X’s investment portfolio?
- Will the Rentails project meet its FEED and environmental approval timelines to enable a final investment decision in 2026?
