Gunnison Copper Mobilizes Mining Fleet at the Johnson Camp Mine in SE Arizona

December 16, 2024

Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS) ("Gunnison" or the

“Company”) is pleased to provide a construction update for the fully permitted Johnson Camp Mine

("JCM"), in southeast Arizona, with first copper production anticipated mid 2025.

Further to the construction update from the press release dated August 8th, 2024, where it was announced

construction of the new leach pad, including crushing of the over-liner material, had commenced the

Company is pleased to report that the mining fleet has been mobilized, and mining activities such as pre-

stripping have begun.

Construction of the Johnson Camp Mine is fully funded by Nuton LLC (“Nuton”), a Rio Tinto venture.

Gunnison is the owner and operator of the mine which has a production capacity of up to 25 million

pounds of copper cathode per year to directly supply critical American supply chains in the clean energy,

defense, and manufacturing sectors.

“We are extremely pleased with how well the JCM construction is progressing. We are tracking our major

construction milestones and budget, including mobilization of the mining fleet and leach pad construction.

The successful start of mining activities was made possible by our highly talented local workforce of over

150 employees and third party contractors, reflecting our commitment to workforce development and

local area economic stimulus,” comments Robert Winton, SVP Operations and General Manager of

Gunnison Copper. “From concept to first production measured in months is a testament to our partnership

with Nuton and the support of the 3 engineering firms contributing to this industry first.”

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 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 yielding robust

economics including an NPV8% of $1.3Billion, 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 under construction with first copper production in

H1 2025, 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.

November 14, 2024 entitled “Gunnison Copper Announces Preliminary Economic Assessment of Open

Pit Mining at its Flagship Gunnison Project in Arizona’s Copper Belt”.

Dr. Stephen Twyerould, Fellow of AUSIMM, President and CEO of the Company is a Qualified Person

as defined by NI 43-101. Mr. Twyerould has reviewed and is responsible for the technical information

ABOUT NUTON

Nuton is an innovative venture that aims to help grow Rio Tinto’s copper business. At the core of Nuton

is a portfolio of proprietary copper leaching related technologies and capability. Nuton offers the potential

to economically unlock copper through leaching, including from primary sulfide resources, achieving

market-leading recovery rates and contributing to an increase in copper production at new and ongoing

operations. One of the key differentiators of Nuton is the ambition to produce the world’s lowest carbon

footprint copper while having at least one Positive Impact at each of its deployment sites, across its five

pillars: water, energy, land, materials and society.
