Federal Court Hands Bunker Hill Mining Significant Summary Judgment
Victory Over Crescent
Court dismisses Crescent’s federal CERCLA claims in their entirety, rejects its bid to force a mine dewatering, and
bars years of its remaining claims as time-barred — while preserving Bunker Hill’s own claim to recover Crescent’s
share of mine remediation costs
KELLOGG, Idaho and VANCOUVER, British Columbia, June 26, 2026 -- Bunker Hill Mining Corp. (“Bunker Hill ” or the
“Company”) (TSX: BNKR | OTCQB: BHLL ) is pleased to announce that the United States District Court for the District of
Idaho has issued a Memorandum Decision and Order delivering a significant summary judgment victory for the Company on
multiple key claims in the ongoing litigation brought by Crescent Mine, LLC (“Crescent”) against Bunker Hill. The Court
dismissed the core of the case that Crescent initiated in July 2021, while also preserving Bunker Hill’s primary claims against
Crescent, keeping the Company on the offensive.
“This decision puts Bunker Hill firmly on the offensive,” said Sam Ash, President and Chief Executive Officer of Bunker Hill .
“The Court dismissed Crescent’s entire federal case, rejected its demand to force us to drain the mine, and barred years of its
remaining claims — all while preserving our claim to make Crescent pay its fair share of water management costs. We are
confident in our position as we press forward with our claims against Crescent.”
Central to the decision, the Court denied Crescent’s attempt to dismiss Bunker Hill’s CERCLA Section 113(f) contribution
claim, holding that the claim “remains viable” and will proceed at trial. Through that claim, Bunker Hill seeks to hold Crescent
financially accountable for its share of the costs of managing and remediating the contaminated water from the Bunker Hill and
Crescent mines. With the claim preserved, Bunker Hill intends to diligently pursue a judgment for the dollar amount, requiring
Crescent to pay its share of those costs.
At the same time, the Court delivered a significant summary judgment against Crescent, granting the summary judgment
motions of Bunker Hill and co-defendant Placer Mining Corporation (“Placer”) and dismissing both of Crescent’s federal
CERCLA claims — a cost-recovery claim under Section 107(a) and a declaratory-judgment claim under Section 113(g) — in
their entirety. These federal claims formed the centerpiece of Crescent’s case against the Company.
The Court also rejected Crescent’s attempt to force Bunker Hill to drain the mine, holding that any such remedial action falls
within the exclusive authority of the U.S. Environmental Protection Agency (“EPA”) rather than the courts, and granted Bunker
Hill and Placer summary judgment on that issue. Notably, the Company continues to work with the EPA to manage
contaminated mine waters pursuant to an established agreement between the Company and the EPA.
The Court further granted Bunker Hill summary judgment dismissing substantial portions of Crescent’s state-law tort claims for
trespass, nuisance, and negligence, holding that any damages claimed for alleged nuisance or negligence occurring before
August 2017, or alleged trespass occurring before August 2018, are barred by the applicable statutes of limitations. The Court
also denied Crescent’s own motion for summary judgment in nearly all respects, rejecting Crescent’s bid to establish liability
against the Company. A narrow set of Crescent’s state-law claims, limited to alleged damages within a roughly three-year
window, remains to be resolved at trial.
The ruling does not affect Bunker Hill’s ongoing mine restart activities or operations, which, as previously announced, remain
on track to produce the first batch of concentrate for sale by the end of this month.
