The deposit was always real. That's the thing that makes the Celsius Resources story in the Philippines so interesting and so instructive: the geology delivered. What the company is fighting over now has almost nothing to do with the rock.
Here is the full account — from the first drill hole in Kalinga in 2006 to the arbitration proceedings consuming the company twenty years later.
The find: Kalinga, 2006
Celsius Resources did not start out as a copper company. It was incorporated in 1986 in Perth as Celsius Coal Limited, a coal explorer with no particular claim to fame. The pivot that matters happened in the mid-2000s when the company acquired exploration rights in the Cordillera Administrative Region of Northern Luzon in the Philippines — a rugged highland zone that had yielded copper and gold for artisanal miners for generations and had attracted minimal systematic modern exploration.
The target was Barangay Balatoc, in the municipality of Pasil, Kalinga Province — roughly 320 kilometres north of Manila. The company renamed itself Celsius Resources in December 2016, signalling that coal was done and critical metals were the story.
Drilling ran from 2006 to 2013. By the end of that program, the company had a picture of something substantial: a large porphyry copper-gold system, the kind that typically forms the backbone of multi-decade producing mines. The technical name for the project was and is the Maalinao-Caigutan-Biyog project, abbreviated MCB. The operating vehicle was a Philippine-incorporated entity, Makilala Mining Company Inc. (MMCI).
The problem was that nothing could move. The Philippine government had placed a moratorium on new large-scale mining agreements that would last, in its original and extended form, nearly nine years. All Celsius could do was hold the ground and wait.
The moratorium lifts — and the race begins
In April 2021, the Duterte administration lifted the mining moratorium, reopening the path to Mineral Production Sharing Agreements (MPSAs) and Financial or Technical Assistance Agreements (FTAAs). For Celsius, the starter's pistol had finally fired.
The company moved quickly. In January 2021 it declared a maiden JORC-compliant Mineral Resource for MCB. By December 2021 it had completed a scoping study, and the Philippines Mines and Geosciences Bureau (MGB) director had declared MCB a priority project — a designation that carries real weight in a bureaucracy where permitting backlogs are measured in years.
The project's technical case was straightforward. MCB sat atop a high-grade underground orebody suited to sub-level stoping with paste backfill — meaning no tailings dam, a feature that tends to get a project through environmental review faster. The scoping study posted a post-tax NPV of US$464 million and an IRR of 33% at then-current copper prices. The capital cost estimate was US$254.7 million. The C1 copper cost in the first decade was projected at US$0.56 per pound — well below the cost curve. On paper, it worked.
What Celsius still needed was a mine permit and a legal structure that could hold one.
The 60/40 problem — and the Sodor solution
The 1987 Philippine Constitution reserves natural resource extraction to Philippine nationals or to corporations at least 60% Filipino-owned. An MPSA can only be held by a company that clears that threshold. MMCI, as a subsidiary of an Australian-listed company, did not.
The structure Celsius chose was the one most foreign miners in the Philippines use: find a credible Filipino partner, transfer 60% of the Philippine operating entity to them, retain 40%, and build the economic rights back into a broader agreement. It is legal. It also means you do not control the company that holds your mine.
In March 2023, Celsius entered a binding deed with two privately held Philippine companies: Sodor Inc. (to acquire 60% of MMCI for approximately PHP 300 million, or about US$5 million) and PMR Holding Corp. (to invest approximately US$38 million into PDEP Inc., the planned downstream processing vehicle). Together, Sodor and PMR were to receive a 30% economic interest in the project. The completion deadline was set, and later extended to 16 February 2026.
Celsius's executive chair at the time was Atty. Julito "Sarge" Sarmiento, a Philippines-based lawyer and mining industry figure whose role bridged both the company and the local operating entity. Sarmiento signed the MMCI-NCIP memorandum of agreement on behalf of MMCI and was the public face of the project's community engagement in Kalinga. His later departure from that role — and the direction he took afterwards — became one of the more consequential developments in the dispute.
The permit: March 2024
In March 2024, the MGB issued the MPSA for MCB. It was, by the MGB's own account, the first new copper MPSA in the Philippines in approximately 15 years — a milestone that reflected both the quality of the project and the political lift that came with its priority designation. The permit covers roughly 2,500 hectares and runs for 25 years with a 25-year renewal option.
The MPSA was issued to MMCI, now nominally 60% Filipino-owned through the Sodor arrangement, satisfying the constitutional requirement.
The indigenous consent question: a required step taken out of order?
Before the mining permit, there was a second required clearance. The Indigenous Peoples Rights Act (IPRA, Republic Act 8371) requires that any project affecting ancestral domains obtain Free, Prior and Informed Consent (FPIC) from the indigenous community, certified by the National Commission on Indigenous Peoples (NCIP), before activities can proceed. The NCIP issues what is called a Certification Precondition.
Celsius's Certification Precondition arrived in September 2024 — six months after the MPSA was granted in March 2024.
The company described the FPIC process as spanning more than three years of community engagement with the Balatoc Indigenous Cultural Community (ICC), culminating in a Memorandum of Agreement signed by MMCI, the Balatoc ICC, and the NCIP. Celsius called it "arguably one of the most stringent approval milestones for a new project to achieve."
Not everyone in Balatoc agreed with that characterisation. And in June 2026, they said so formally.
"Deceptive tactics and forged signatures": the June 2026 petition
On June 10, 2026, members of the Balatoc ICC filed a petition with the NCIP Regional Office — copies to the Department of Environment and Natural Resources and other agencies — seeking immediate revocation of both the MPSA and the Certification Precondition.
The petition made serious allegations. The petitioners claimed the company used "deceptive tactics and forged signatures" to secure consent for the 2022 MOA. They argued the MPSA was unlawfully issued before the NCIP precondition was in place, violating the IPRA's required sequencing. And they alleged that the project had brought militarisation into the community — private armed personnel, red-tagging of residents who opposed the mine — and that mining would threaten the Pasil and Chico river basins on which the community depends.
These allegations have not been adjudicated. Celsius has contested them. What is beyond dispute is that a formal legal petition to cancel the mine permit now sits alongside the company's arbitration proceedings. The permit is under challenge from below and the governance structure is under challenge from within.
This pattern — community members disputing the authenticity and completeness of FPIC processes after the fact — is not unique to Celsius. Amnesty International documented similar allegations across multiple Philippine nickel and gold projects in 2025, noting inadequate consultation and coercion as recurring problems in NCIP-certified processes. The Balatoc petition fits a recognisable national pattern, which does not make the specific allegations true — but it does mean they should be taken seriously rather than dismissed as routine opposition noise.
The orebody gets better — and the structure fails
Through 2025, the project itself kept delivering. In October 2025, Celsius reported high-grade extensions to the MCB deposit. In December 2025, the company booked its maiden JORC Ore Reserve: 130.3 million tonnes at 0.66% copper and 0.21 grams per tonne gold — 22.1 million tonnes Proven and 108.2 million tonnes Probable. Contained metal: 856,000 tonnes of copper and 891,000 ounces of gold. For an ASX small-cap with a market capitalisation that has oscillated below A$50 million, this is a genuinely significant orebody.
Also in early 2025, Celsius secured a US$76.4 million bridge loan facility from Maharlika Investment Corporation, the Philippine sovereign wealth fund — a signal of government-level interest in bringing the project into production.
And then, in February 2026, the Sodor payment deadline expired without payment.
The collapse: February–July 2026
What followed has been, by any measure, a governance implosion.
February 2026: Deadline passes. Celsius issues a formal relinquishment notice, demanding Sodor return its 60% of MMCI. Sodor attempts payment approximately 30 days late. Celsius rejects it as out of time.
March–April 2026: Sodor and PMR file for arbitration, contesting the relinquishment and arguing that PMR's subscription obligation is not yet enforceable. Celsius files its own arbitration seeking enforcement. An April 21 conflict-resolution ruling initially goes Celsius's way. But Sodor then requisitions an MMCI shareholders' meeting, vacates the board, and reinstates Sarmiento — Celsius's former executive chair and the man who signed the FPIC agreement — as MMCI's chair and president.
May 5, 2026: The arbitral tribunal denies Celsius's interim orders. Sodor's 60% stake and its grip on the MMCI board remain in place pending full arbitration. Celsius does not control the company that holds its mine.
May–June 2026: A second front opens. Maharlika's US$76.4 million MMCI loan is assigned to Equinaire Holdings, a subsidiary of Kiri Industries — a Bombay Stock Exchange-listed Indian chemical and dyestuff company that has stated publicly its intention to use the loan as leverage to secure a preferential offtake agreement for MCB copper ore, for a planned processing facility in India. Celsius says it had no knowledge of the Maharlika-Kiri transaction. It argues its own unit, PDEP Inc., is the proper concentrate counterparty and files emergency arbitration to block any Kiri-MMCI offtake deal not approved by Celsius, while simultaneously stating it welcomes direct offtake discussions with Kiri as part of project financing.
There is also an internal governance event. Celsius terminated executive director Neil Grimes after what its board characterised as an unauthorised notice directing Sodor's shares to an entity called Socialej Inc., flagged for related-party concerns. New managing director Bardin Davis arrived in April; Peter Hume is now interim chair. The Celsius board has been substantially reshuffled.
July 2026: The investment decision has been pushed to late 2026. The feasibility study update, targeted for December 2025, is still in progress. A 1-for-20 share consolidation is effective July 23, 2026. Celsius's market capitalisation sits at approximately A$34.5 million — a number that reflects the depth of the uncertainty, not the size of the orebody.
What we are watching
The Celsius story in the Philippines has at least four open threads, any one of which could determine the project's fate:
1. Arbitration over MMCI control. The core question — does Sodor's 60% remain valid, or did it lapse when payments weren't made? — will be decided by the arbitral tribunal. The May 2026 interim decision went against Celsius, leaving Sodor on the board. A full ruling is pending.
2. The Kiri offtake dispute. Who captures the copper concentrate economics — PDEP (Celsius's processing vehicle) or an Indian chemical company that entered the picture through a sovereign loan assignment — is a second, partially separate legal proceeding.
3. The Balatoc FPIC petition. If the NCIP or the courts find that the Certification Precondition was procedurally defective — or that the MPSA was issued before the IPRA precondition was satisfied — the mine permit itself could be voided. This is a lower-probability but higher-consequence outcome.
4. Financing. Whoever wins the governance fight still needs to fund a US$254.7 million underground mine development. The Maharlika facility is now in Kiri's hands. A fresh financing package, or an offtake-anchored project finance structure, needs to be assembled before a spade goes in the ground.
A world-class orebody in the Philippines is not enough. You also need to own the company that holds it. Celsius is fighting to get that back.
We covered the structural reasons this keeps happening in our earlier piece on the 60/40 rule and the Anti-Dummy Law. The Celsius situation is the case study in real time. We'll stay on it.
