Marimaca Copper ended September with US$126.6 million in cash and US$135.5 million in net working capital, giving the pre-revenue Chilean developer funding visibility for at least the next year. A potential US$17.3 million VAT recovery could add to that liquidity in the first half of 2027, but the Marimaca Project has not yet reached demonstrable technical feasibility or commercial viability.
- US$126.6 million in cash and cash equivalents at September 30
- US$135.5 million in net working capital, excluding current lease liabilities
- US$17.3 million Chilean VAT recovery expected in the first half of 2027, subject to eligibility
- Marimaca Project remains classified as an exploration and evaluation asset
- Further financing may be required to advance the project beyond the next 12 months
Cash runway strengthened by February equity financing
Marimaca Copper Corp. (ASX:MC2) finished the September quarter with US$126.6 million in cash and cash equivalents, a substantial increase from US$66.8 million at December 31, 2025. Net working capital, excluding current lease liabilities, stood at US$135.5 million. The company says that position is sufficient to meet its obligations, property option payments and planned operating needs for at least the next 12 months.
The balance reflects the company’s February 2026 global treasury and secondary offering, which generated gross proceeds of C$409 million across the Canadian and Australian markets. Marimaca received proceeds only from the Canadian treasury component, recording net proceeds of C$129.2 million, while the secondary transactions transferred existing shares and raised no money for the company. The scale of that capital event was covered in the earlier February equity financing, which was reported alongside a US$150.9 million cash balance at June 30.
US$17.3 million VAT recovery moves toward application
Marimaca has classified US$17.3 million of Chilean value-added tax credits as a current asset after determining that the recognition criteria for recovery were met at the end of 2025. The company expects to begin the formal refund application process in late 2026 and anticipates recovering the balance during the first half of 2027.
That timetable is an expectation rather than a committed inflow. Recovery remains subject to statutory eligibility, administrative processes and project execution timelines, and the financial statements warn that the actual amount and timing could differ. A US$0.5 million expected credit loss was also recognised against a separate receivable during the nine-month period, reducing its carrying value to US$0.9 million after a US$1 million cash receipt.
Marimaca Project remains pre-development
The central accounting message is more cautious than the cash figure. Management concluded that the technical feasibility and commercial viability of extracting mineral resources from the Marimaca Project were not yet demonstrable at September 30, so project costs remain classified as exploration and evaluation assets rather than mineral property development costs.
The assessment considers feasibility work, engineering definition, permits, financing progress, board support, detailed engineering commitments and remaining technical and commercial uncertainties. The company reported no impairment indicators on its exploration and evaluation assets. Its regional growth options remain active, including Pampa Medina and the Madrugador Project, with total staged consideration of up to US$12 million for each property. The Pampa Medina option sits alongside high-grade Pampa Medina drilling, which earlier reported a 216-metre sulphide intersection grading 0.96% copper and 7.2 grams per tonne silver.
Financing remains the longer-term constraint
Marimaca is still pre-revenue and funds its activities primarily through equity financing. The interim statements therefore draw a clear line between near-term liquidity and the longer-term funding required to advance the project: management believes the company can operate for at least 12 months, but says continued development beyond that period will depend on obtaining additional financing, with no assurance that suitable funding will be available on favourable terms.
The next material checkpoints are the Chilean VAT application, the timing and outcome of any refund, progress in feasibility and permitting work, and any decision to commit to detailed engineering or a Final Investment Decision. Until those milestones arrive, Marimaca’s large cash balance provides time, but not yet a production date.
Bottom Line?
Marimaca has bought itself funding time, while the VAT refund could extend that runway. The harder question is when project definition and financing will be strong enough to support a development decision.
Questions in the middle?
- Will Marimaca satisfy the statutory and administrative requirements needed to recover the US$17.3 million VAT balance in the first half of 2027?
- How much of the current cash balance will be committed to feasibility, permitting, regional options and early development work?
- What additional financing will be required before the Marimaca Project can move beyond exploration and evaluation status?
