NEWS RELEASE
Gunnison Copper Repays US$7.3 Million of Nebari Secured Debt, Fully
Eliminating Non-Convertible Portion of Second ARCA
Major Deleveraging Milestone Achieved as Company Moves to Fully Eliminate Nebari Debt
December 1, 2025
Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) (“Gunnison” or the
“Company”) is pleased to announce that it has fully repaid the US$7.3 million non-convertible principal
portion of the Second Amended and Restated Credit Agreement (“Second ARCA”) with Nebari Natural
Resources Credit Fund I LP (“Nebari”). All amounts in this news release are in United States dollars
unless otherwise noted.
Following this repayment, the only remaining balance outstanding under the Second ARCA is the $5.25
million convertible principal amount, which Nebari retains the right to convert to equity under the
previously announced terms and is less than the net proceeds expected through the monetization of the
48C tax credits.
“Reducing and ultimately eliminating debt has been a core objective of management,” said Craig
Hallworth, Senior Vice President and Chief Financial Officer of Gunnison Copper. “Fully repaying the
non-convertible portion of the Nebari financing marks a major step forward in strengthening our balance
sheet and capital structure. This achievement enhances our financial flexibility and advances our goal of
fully retiring the remaining Nebari secured debt.”
ABOUT GUNNISON COPPER
Gunnison Copper Corp. is a multi-asset pure-play copper developer and producer that controls the
Cochise Mining District (the district), containing 12 known deposits within an 8 km economic radius, in
the Southern Arizona Copper Belt.
Its flagship asset, the Gunnison Copper Project, has a Measured and Indicated Mineral Resource
containing over 831.6 million tons with a total copper grade of 0.31% (Measured Mineral Resource of
191.3 million tons at 0.37% and Indicated Mineral Resource of 640.2 million tons at 0.29%), and a
preliminary economic assessment ("PEA") yielding robust economics including an NPV8% of $1.3 billion,
IRR of 20.9%, and payback period of 4.1 years. It is being developed as a conventional operation with
open pit mining, heap leach, and SX/EW refinery to produce finished copper cathode on-site with direct
rail link.
The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too
speculative geologically to have the economic considerations applied to them that would enable them to
be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be
realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
In addition, Gunnison's Johnson Camp Asset, which is now in production, is fully funded by Nuton LLC,
a Rio Tinto Venture, with a production capacity of up to 25 million lbs of finished copper cathode annually.

Other significant deposits controlled by Gunnison in the district, with potential to be economic satellite
feeder deposits for Gunnison Project infrastructure, include Strong and Harris, South Star, and eight other
deposits.

Preliminary Economic Assessment" dated effective November 1, 2024 and available on SEDAR+ at
