Minto Metals: the $44 million claim that waits on a restart decision

PricewaterhouseCoopers Inc., receiver of Minto Metals Corp., asks the Supreme Court of Yukon for no order in its Ninth Report, dated October 21, 2026 and filed the next day. The report's stated purpose is to update the court and stakeholders on the receiver's activities, the post-closing matters left by the sale of the Minto mine, the mine's potential restart and the claims asserted against the estate. As at September 30, 2026, the receiver was holding approximately $2,433,664.94 in cash. The report says the receiver is not making an application for a distribution order "until there is more clarity" about one claim: the Government of Yukon's, asserted as a super-priority claim of approximately $44 million for estimated future remediation, reclamation and closure costs that may be incurred if the mine's buyer, Selkirk Mining Corp., decides not to restart it. That decision, the report says, is anticipated in mid-2027, per the Receiver's Ninth Report, Oct. 21, 2026, paras. 1.6–1.8, 5.14, 5.16, 5.23.

Eight months earlier the receiver intended to apply for one. On February 12, 2026, its counsel, Lawson Lundell LLP, sent the service list a preliminary analysis of the miners' lien claims and wrote that, once comments closed on March 13, the receiver intended to schedule an application for a distribution order based on it. The analysis found priority lien claims totalling $12,464,761.01, put the funds that may be available for distribution at an estimated $2,358,284.31, and anticipated that each lien claimant with a priority claim "may receive a recovery of 19%" of it. The three secured creditors, it concluded, "will receive no recovery on their claims." It did not incorporate the government's claims, which the receiver says Yukon's counsel raised after the analysis went out, by reference to a letter dated August 27, 2025 that did not reach the personnel administering the estate until February 13, 2026, per the Receiver's Ninth Report, Oct. 21, 2026, para. 5.13, and App. B, cover letter of Feb. 12, 2026, p. 23, and Preliminary Lien Analysis, paras. 6.1–6.4.

A copper mine on Selkirk First Nation land

Minto Metals, incorporated in British Columbia in November 2021 through a reverse takeover by Minto Explorations Ltd., ran a copper-gold-silver mine 240 kilometres northwest of Whitehorse, on Category A Settlement Land of the Selkirk First Nation, "and as such the land is owned by SFN." The mine had changed hands several times; Capstone Mining Corp. owned Minto Explorations from 2008 until it sold it to Pembridge Resources PLC in 2019, per the receiver's Receiver's First Report, Nov. 2, 2023, paras. 2.1–2.4.

By the receiver's account, Minto's financial difficulties began in early 2022 with a lack of capital and were made worse by its inability to fund an increase in its reclamation security. That security, required by its Quartz Mining Licence, stood at $72 million in 2019, posted as a surety bond issued by Zurich Insurance Company Ltd. and indemnified by Capstone. After Minto revised its reclamation and closure plan in 2022, the Minister of the Department of Energy, Mines and Resources set the figure at $104 million, and Minto was granted approval to reduce it to $93 million; unable to fund the $21 million increase in cash or win approval for a larger surety bond, it paid approximately $3 million under a payment plan but "was ultimately unable to meet any further obligations." It was placed under restricted operating conditions, which the receiver says kept it from generating sufficient cash flows from mining. By May 2023 more than 20 liens had been registered against it. On May 12, 2023, Minto "made the decision to abandon the Minto Mine." Its employees were terminated, its directors resigned the next day, and the Yukon government put its own contractors on site to carry out Minto's environmental obligations, per the Receiver's First Report, Nov. 2, 2023, paras. 2.12–2.21.

The Supreme Court of British Columbia appointed PwC limited receiver over certain copper concentrate on June 29, 2023, on the application of Sumitomo Canada Limited. On July 24, 2023 it appointed PwC receiver and manager of all of Minto's property, and on August 25, 2023 the Supreme Court of Yukon took the proceeding over, under No. 23-A0086. In two transactions, the receiver sold "the majority of Minto's tangible and intangible assets" to 843093 Yukon Inc., which the February analysis describes as "a wholly owned subsidiary of Selkirk First Nation": buildings and certain rolling equipment, closed on September 10, 2024, and the intangible assets, including mineral claims, leases and permits, closed on June 18, 2025. On December 17, 2025, 843 amalgamated with 1546139 B.C. Ltd. to form Selkirk Mining Corp., per the Receiver's Ninth Report, Oct. 21, 2026, p. 1, paras. 1.1–1.6, 2.1.1.1, 5.17.1, and App. B, Preliminary Lien Analysis, para. 1.2.

The licences the receiver kept

The intangibles sale left behind the two licences a restart would require. The buyer would need an assignment of the Type A Water Licence and the Quartz Mining Licence only if it chose to recommence mining. At 843's request, the receiver agreed to keep holding them, passively, for up to five years after closing; if they lapsed, the receiver explained, "the application process could take many years and be very costly," per the Receiver's Eighth Report, May 29, 2025, paras. 3.8–3.10. A letter from the government gives the receiver "certain assurances" about the obligations under those licences, "subject to its terms and conditions." Selkirk Mining began drilling in August 2025, and the receiver understands that it assumed care and control of the mine on April 1, 2026, "at which time YG paused its reclamation activities," per the Receiver's Ninth Report, Oct. 21, 2026, paras. 3.2–3.3, 4.2.

As part of its evaluation of a restart, Selkirk Mining proposed to dewater the underground mine. Its updated plan of August 13, 2026 contemplates the phased removal of approximately 1.5 million cubic metres of water, with measures addressing, among other things, monitoring, cost tracking and "the potential reversal of the proposed activities." Because it still holds the licences, the receiver says "a framework is required to define SCM's responsibilities, preserve YG's regulatory oversight and address the Receiver's obligations and required protections as licence holder." At a meeting of the receiver, Selkirk Mining and the government on June 17, 2026, a court order was identified as the preferred means, and the receiver has circulated a draft to them and to the Selkirk First Nation; among the matters being considered was what would be required if Selkirk Mining decides not to restart, "including any measures required to reverse, remediate or otherwise address the effects of the proposed activities." The report says the preconditions and authorizations for dewatering "have not yet been achieved" and the framework has not been finalized, per the Receiver's Ninth Report, Oct. 21, 2026, paras. 4.1, 4.3, 4.5, 4.7, 4.9–4.11.

Yukon's claim, in its own words

The government's letter, from its counsel Thornton Grout Finnigan LLP, is attached to the Ninth Report and submits a proof of claim for $44,394,207. The surety bond "has now been fully drawn," it says, and the remediation costs are approximately $103.3 million. A schedule to the proof of claim sets out the costs the government incurred through the second quarter of 2024 and those it expects to incur over each of the next 20 years: an estimated 20-year cost of $119,394,207, "being $44,394,207 more than the Reclamation Security furnished by Minto," per the Receiver's Ninth Report, Oct. 21, 2026, App. C, YG Claim Letter, Aug. 27, 2025, pp. 68, 70–71.
