Gunnison Copper Commences "High-Value- Add" Work Programs at the Gunnison Copper Project in Southeast Arizona
Gunnison Copper Commences "High-Value-
Add" Work Programs at the Gunnison Copper
Project in Southeast Arizona
Phoenix, Arizona--(Newsfile Corp. - April 14, 2025) -
Gunnison Copper Corp. (TSX: GCU) (OTCQB:
GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company")
is pleased to announce that the high-value-
add ("HVA") work programs have commenced at the Gunnison Copper Project ('Project') in southeast
Arizona, including mobilization of the drill rig later this week. All dollar amounts in this press release are
in United States dollars.
"The fully funded HVA programs are differentiating factors for the Project over our peers in Arizona,"
states Roland Goodgame, Gunnison SVP of Business Development. He adds,
"Several of the HVA
programs, such as the overburden by-product monetization and mineralized material sorting are
opportunities that are unique to the Gunnison Copper Project due to the geological environment.
These programs, if successful have the potential to materially enhance the Project's already positive
economics and provide guidance for the PFS. We are moving both of our mines forward at a pivotal
time for copper in Arizona and in the USA, meeting the need for domestic production."
In preparation for the Gunnison Copper Project pre-feasibility study ("PFS"), the Company has decided
to first complete what it has identified as the high-value-add work programs. The programs are expected
to take 3-6 months to complete and consist of (See Figure-1):
Gravel By-Product Revenue -
759 million tons of alluvial gravel is expected to be mined during
the mine life and is already fully costed in the Gunnison Copper Project Preliminary Economic
Assessment ("PEA"). Gravel, as an aggregate or rock product, is a potential source of by-product
revenue. The planned rail spur and railyard increases the range the Company can profitably sell the
gravel with access to larger markets such as Phoenix, Los Angeles, Houston, and Dallas. As
detailed in the PEA, if just 10% of this material could be sold for revenue of $5/ton, it could
potentially add $380M in revenue to the Project. The revenues associated with such sales are not
anticipated to have any material costs (aside from marketing costs) as the material has already
been mined and does not require further processing*.
Limestone By-Product Revenue -
85 million tons of limestone is also expected to be mined,
and already included in the PEA mining cost, at the Gunnison Copper Project. Crushed limestone
is a highly valuable commodity in cement, aggregate, chemical and agricultural industries, selling
for between $20/ton and over $60/ton in the region. As detailed in the PEA, if 50% of this
limestone could be sold at $20/ton it could generate approximately $850M in additional gross
revenue. The revenues associated with such sales are not anticipated to have any material costs
(aside from marketing costs) as the material has already been mined and does not require further
processing*.
Mineralized Material Sorting -
Copper oxide exists on visually distinct blue-green and red-brown
zones that are ideally suited to optical mineralized material sorting. Preliminary testing was 100%
successful and data suggest sorting of this material has the potential to greatly reduce acid
consumption and volume of material leached by removing 40 to 50 percent of the process stream
as unmineralized, higher acid consuming, waste (See Figure-2). This would result in significant
savings on operating costs. A drill rig has been mobilized to drill 3 holes totaling 4,500 feet
targeting oxide mineralization in the Martin and Abrigo formations. The holes will undergo
extensive mineralogical testing and assaying followed by mineralized material sorting and
analysis.
Sulfide Investigation -
Sulfide mineralization occurs in the bottom of the Gunnison Copper
Project open pit design. Due to the previous ISR mining method the sulfide potential has been
mostly untested. The plan is to collect appropriate samples and initiate metallurgical test work. The
sulfides have the potential to add mine life, production rate and excite strategic interest such as the
recent interest from Nuton LLC (a Rio Tinto Venture) who have an agreement with Gunnison to test
the suitability of its proprietary sulfide leaching technology for the Project's sulfide resources (
see
press release dated March 3, 2025
).
Permitting -
Gunnison's prior permitting and community track record is excellent. There is no
federal permitting required and is only a state run process. The Gunnison Copper Project is
permitted today for in-situ recovery; however, amendments are needed. The Company will begin
collecting the data needed to commence this amendment process.

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.
Gunnison exists to develop and operate copper mines in Southern Arizona to produce fully Made in
America finished copper cathode to directly supply American energy, defense, and manufacturing supply
chains.
Gunnison proudly hires locally, purchases locally, and sells its products locally.
Gunnison invests
in its employees, their families, and the communities around it.
Gunnison operates safely and
responsibly with a focus on technology and positive societal impact, while also emphasizing long-term
value creation for stakeholders.
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 a
preliminary economic assessment ("
PEA
") 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
expected in Q3 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.

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