96% of Analyzed Limestone Meets Industrial Specifications for Several Saleable Products, Unlocking Value for Updated PEA Expected in Q1 2026

Phoenix, Arizona--(Newsfile Corp. - October 23, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to report positive results from its ongoing High-Value-Add Work Program evaluating the commercial potential of limestone occurring within the planned Gunnison Open Pit mine plan in southeast Arizona. The evaluation indicates that a substantial portion of the limestone, material that is currently scheduled as waste in the mine plan, is suitable for a range of industrial end-use markets, including cement, agricultural lime, and premium paper filler/paint and coatings.

"These initial results suggest a significant opportunity to unlock value from material previously categorized as waste, with potential to supply cement, agricultural lime, and premium filler markets," said Roland Goodgame, SVP Business Development. "As part of our High-Value-Add Work Program, this limestone evaluation could enhance project economics by diversifying revenue and reducing waste handling, and we intend to integrate these findings into our updated PEA expected in Q1 2026, with PFS work already underway."

Limestone Evaluation Highlights:

• Sampling Basis: Historical drill holes NSD-40, NSD-41, and NSD-43 were reviewed. Whole-rock analysis (XRF and ICP-MS) was completed on 883 feet of limestone core, representing ~39% of the total logged limestone in these holes.
• Industrial Suitability: Approximately 96% of the analyzed material met indicative thresholds for cement and agricultural lime applications, averaging >96% calcite and >55% CaO.
• Premium Applications: Approximately 21% of the analyzed material met indicative thresholds for premium paper filler/coating and high-brightness paint/coatings applications, averaging >97% calcite and ~56% CaO.
• Scale of Opportunity: The current mine plan schedules approximately 224 million tons of limestone as waste over the contemplated 16-year mine life. Based on the representativeness of these intersections and visual similarity of non-assayed intervals, the Company believes the proportion of commercially suitable material could increase following further analysis.

Context and Methodology:

• The limestone evaluation forms one pillar of Gunnison's broader High-Value-Add Work Program, which also includes mineral sorting (See initial results announced September 15^th, 2025), metallurgical optimization, and mine plan refinements intended to improve recoveries, lower operating costs, and enhance head grades.
• Whole-rock (XRF/ICP-MS) data were used to approximate industrial suitability; final product qualification for specific end-uses will require additional specification-driven testing (e.g., brightness/whiteness, abrasiveness, particle size distribution, deleterious elements, and pilot-scale processing where applicable).

Next Steps:

• Expand sampling coverage beyond the initial 883 feet to improve statistical confidence across the planned open pit area.
• Conduct specification-based test work (e.g., brightness/whiteness indices, deleterious screening, grindability) aligned to cement, ag-lime, and premium filler/paint product standards.
• Advance mine plan and materials-handling trade-offs (selective mining, in-pit stockpiling, on-site sizing) to define practical pathways to market.
• Evaluate logistics, permitting, and commercialization options, including potential marketing partnerships and offtake discussions, for incorporation into the updated PEA (Q1 2026) and the PFS scope.

All drill holes have been drilled using diamond drill rigs to generate HQ sized core. Whole core was sent to independent laboratory ALS Global in Reno, Nevada for Wholerock analysis including major, minor and trace elements. Pulps and sample rejects are stored by Gunnison for future reference.

Winton Led the Successful Restart of America's Newest Copper Mine, Johnson Camp, Within One Year of Breaking Ground

Phoenix, Arizona--(Newsfile Corp. - October 9, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company"), America's newest copper producer, is pleased to announce the promotion of Robert Winton to the role of Chief Operating Officer (COO), effective immediately.

Mr. Winton has been with the Company since August 2020, serving as Senior Vice President Operations and General Manager. He has played a pivotal role in transforming the Johnson Camp Mine from care-and-maintenance into a fully operational mine, culminating in first copper production and commercial sales in 2025, establishing Gunnison as a new U.S. copper producer.

"Robert's promotion is a well-deserved recognition of his exceptional leadership and operational expertise," stated Stephen Twyerould, President and Chief Executive Officer of Gunnison Copper. "Under his direction, the team brought the Johnson Camp Mine into production within a year of breaking ground - an extraordinary achievement that reflects his unwavering dedication to operational discipline, safety, and execution excellence. His leadership has been instrumental in embedding a culture of accountability, performance, and safety across our operations."

As Chief Operating Officer, Mr. Winton will oversee all site operations, project development, and integration of upcoming work programs across the Company. He will also continue to advance collaboration with Nuton LLC, a Rio Tinto venture, with first copper production using their advanced bio-leaching technologies expected later this year.

"It's been incredibly rewarding to see the Johnson Camp team deliver America's newest source of copper cathode," said Robert Winton, Chief Operating Officer. "I'm proud of the disciplined foundation we've built and excited to lead Gunnison's next phase of growth as we expand production and help secure America's domestic copper supply."

Mr. Winton brings more than 25 years of experience in mining operations, technical services, and project execution, having previously held senior operational roles with several North American base-metal producers, including Hudbay Minerals, prior to joining Gunnison Copper.

Study Projects a Total Present Value Output Of $14.6 Billion, Supporting More than 53,000 Job-Years of Employment and Generating $2.07 Billion In Labor Income Across the U.S. Economy Over the Life of the Gunnison Project

Phoenix, Arizona--(Newsfile Corp. - October 8, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company"), America's newest copper producer, is pleased to announce the preliminary results of an independent Economic Impact Study conducted by the Eller Partnerships Office at the University of Arizona, which underscores the transformative economic potential of the Company's flagship Gunnison Copper Project in Southern Arizona. All amounts are reported in U.S. dollars (USD) unless otherwise noted.

The study employed nationally accepted economic modeling tools to assess the cumulative potential impact of the Company's flagship Gunnison Project's operations across the national, state, and county levels. The report is currently being finalized, with full publication expected to be available soon.

"The University of Arizona's findings support what we have long emphasized — the Gunnison Copper Project has the potential to not only be a nationally significant source of Made-in-America copper, but also a generational economic driver for Arizona and Cochise County," stated Craig Hallworth, Senior Vice President and CFO of Gunnison Copper. "The projected multi-billion-dollar impact and thousands of jobs over the life-of-mine demonstrate the scale of the opportunity, reinforcing Gunnison's importance to U.S. energy, defense, and manufacturing supply chains."

"Eller Partnerships Office was happy to collaborate with Gunnison Copper on this project, building on the strength of the Eller College in economic impact analysis and the University's strategic focus on sustainable mining," said Anastasiya Ghosh, associate dean, partnerships, Eller College of Management.

Key Report Metrics and Findings Include:

Average Annual Effects (Direct):

• Revenue: $625 million
• Employment: 524 jobs
• Labor Income: $50 million

Combined Direct, Indirect & Induced Effects (Annual):

• National level: $1.43 billion in output, 2,676 jobs, $209 million in labor income
• Arizona: $978 million in output, 1,739 jobs, $129 million in labor income
• District 6, including Cochise County: $880 million in output, 765 jobs, $64 million in labor income

Cumulative Life-of-Mine Impacts:

• United States: $14.6 billion in output, 53,521 job-years, $2.07 billion in labor income
• Arizona: $10.01 billion in output, 34,783 job-years, $1.28 billion in labor income
• District 6, including Cochise County: $9.02 billion in output, 15,308 job-years, $633 million in labor income

All amounts from the study represent the forecasted economic impact of the Gunnison Project in the State of Arizona and nationally in the USA. They do not represent an economic analysis of the Gunnison Project itself and actual economic impact will be determined after the Gunnison Project is developed into an operating mine, which remains subject to completion of a feasibility study, financing and permitting.

The Company also announces that it has received an initial conversion notice from Nebari Natural Resources Credit Fund I LP ("Nebari") pursuant to the terms of the Second Amended and Restated Credit Agreement (the "Second ARCA"). See the Company's press release dated April 24, 2025 for further details of the Second ARCA. The conversion benefits the Company as it reduces the principal amount of the Second ARCA. With a full conversion of the convertible principal amount by Nebari, and the intention to use the proceeds to be received from sale of the previously announced 48C tax credits to repay the non-convertible portion of the Second ARCA, the Second ARCA could be repaid in full.

The initial conversion is for US$500,000 at the conversion price of US$0.2097 (converted from C$0.30), resulting in the issuance of 2,384,358 common shares. Nebari have advised that they are converting for the purpose of sale and may convert further amounts. Nebari has agreed to orderly resale restrictions for any sales made through the Toronto Stock Exchange, such that such sales shall not exceed 10% of the daily trading volume on the Toronto Stock Exchange unless such sale price is not less than a 5% discount to the closing price per Common Share on the previous trading day, provided that, within any 120-day period, the cumulative discount of the sale price as it relates to the closing price on the day prior to the Lender's first sale in such 120 day period shall not exceed 25%.

On September 15, 2025, Gunnison completed its inaugural copper sales, marking the start of revenue generation following successful commissioning. Gunnison sold a total of 225,371 pounds of finished copper cathode at an average realized copper price of US$4.64 per pound, generating gross proceeds of approximately US$1,046,194.

"This milestone represents the first revenue from Johnson Camp and demonstrates the rapid progress Gunnison has made in delivering value to shareholders since achieving first copper production just weeks ago," stated Craig Hallworth, Senior Vice President and Chief Financial Officer. "Strong copper prices and increasing production levels position us well as we move towards a potential equity valuation re-rating as a copper producer. We are especially proud that every pound sold is 100% Made-in-America copper, directly supporting our nation as we work together to strengthen our supply chains."

Key Highlights of First Copper Sales:

• Revenue milestone achieved: First sales total 225,371 lbs. of finished copper cathode, generating over US$1.0 million in gross proceeds.

• Strengthened U.S. supply chain: Sales represent the first Made-in-America copper from JCM delivered into domestic markets.

• Nuton^® Technology: First copper production using Nuton's bio-leaching technology is expected later this year. Nuton , a venture of Rio Tinto, will be deploying this innovative technoogy at scale for the first time at Johnson Camp.

• Continued growth trajectory: JCM has a nameplate capacity of 25 million pounds of finished copper cathode annually.

Johnson Camp Mine commenced production in the last week of August 2025, ahead of schedule, and with an excellent health and safety record.

Evaluating Airborne Georadiotomography (aGRT) for Potential Copper and Rare Earth Targeting

Phoenix, Arizona--(Newsfile Corp. - September 23, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to announce that it has entered into a non-binding Letter of Intent ("LOI") with Lunasonde Inc. ("Lunasonde"), a U.S.-based defense technology start-up specializing in airborne based subsurface imaging.

Under the LOI, Gunnison will provide access to its district-scale land package in southeastern Arizona, allowing Lunasonde to test and refine its advanced experimental remote sensing technology. The goal is to accelerate the identification of new copper, other critical minerals, and rare earth element targets within the Company's Cochise Mining District assets.

"Geology like that of the Cochise Mining District has been known to host at least 12 of the Critical Minerals so important to the US supply chain, yet most of this geology lies, un-explored, beneath thick alluvial cover. We are delighted to explore this partnership with Lunasonde who's technology has the potential to see through this cover and make new discoveries," stated Stephen Twyerould, President & Chief Executive Officer.

"Our partnership presents an unparalleled opportunity to demonstrate how Lunasonde can accelerate critical mineral exploration," says Jeremiah Pate, Lunasonde's Founder and Chief Technology Officer.

The parties intend to apply for funding of this venture under the United States Department of Energy ("DOE") ROCKS (Reliable Ore Characterization with Keystone Sensing) Program. The transaction remains subject to the negotiation and execution of definitive agreements, successful submission and approval of the DOE funding application, and customary closing conditions.

Sorting Tests Reduced Acid Consumption, a Key Operating Cost Driver, on the Highest Acid Consuming Mineralized Material by Approximately 75% While Maintaining Copper Recovery

Phoenix, Arizona--(Newsfile Corp. - September 15, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to announce encouraging results from its initial mineralized material sorting test program at the flagship Gunnison Copper Project in southeast Arizona, one of the largest and most advanced copper development projects in the United States.

"These initial results are extremely encouraging, showing the potential to significantly reduce acid consumption while maintaining copper recovery," stated Roland Goodgame, Gunnison's SVP of Business Development. "This type of high-value-add program can materially improve the Project's already robust economics and feed directly into our upcoming update to our preliminary economic assessment and planned pre-feasibility study. These results support Gunnison's vision of producing cost-effective, sustainable, and 100% Made-in-America copper."

Initial Mineralized Material Sorting Results:

• Sample: A half-ton sample consisting of 2" to 6" pieces of PQ drill core from the Martin Formation, collected as part of Gunnison's recently completed metallurgical drilling program. The Martin Formation is the highest acid consuming rock type in the deposit and makes up ~44% of the resource base. The sample was comprised of ~54% mineralized material and ~46% internal waste, consistent with the overall Martin Formation.
• Waste Reduction: Over 90% of the internal acid-consuming waste was successfully removed from the mineralized material using optical mineral sorting equipment at a commercial scale.
• Acid Consumption Reduction: Due to the removal of the high-acid-consuming waste, the sorted material is expected to require up to 4x lower acid consumption.
• Copper Recovery: Less than 1% of total copper was lost to waste, ensuring strong copper recovery and protecting revenue.
• Testing Location: Initial sorting tests were conducted at Steinert's facilities in Kentucky in August 2025.

Table 1: Results of mineral sorting test work on the Martin Formation from the Gunnison Open Pit resource. 57% of the sample sorted to mineralized and 43% sorted to waste.

*Copper grades estimated from assays on hand-sized samples from recently drilled core

Should further test work remain consistent with the initial testing results, it suggests approximately 40% of the mined Martin Formation can be removed as internal waste by optical mineral sorting prior to processing on the leach pad. This would result in a near doubling of the process head grade, and significantly reduced process operating costs.

Next Steps:

• Optimization testing on different size fractions of the Martin formation
  • Mineral Sorting samples will be crushed at Base Metallurgical Labs in Tucson.
  • Crushed materials will then be returned to Steinert for further mineral sorting tests to determine further liberation and sizing characteristics.
• Following the mineralization being separated from internal waste, column leach testing will be conducted on sorted products.
• Some samples may be sent to Germany for testing using Steinert's advanced M Sorters.
• Incorporating results into updated PEA expected in the first quarter of 2026.

About 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-1). This would result in significant savings on operating costs.

Phoenix, Arizona--(Newsfile Corp. - July 22, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to announce that mineral processing has started with first copper sales expected in September at the fully-permitted Johnson Camp Mine ("JCM"), in southeast Arizona.

"A major milestone for Gunnison Copper has been achieved, as we started leaching copper on July 18, about one year after starting to construct the leach pad," states Robert Winton, SVP Operations of Gunnison Copper. He continues, "Working with our partners, Nuton, M3, Rango, and Schmueser has been a pleasure and the results speak to the incredible dedication and perseverance of the entire team. We have managed to grow our 11 year no lost time accident record at JCM with over 100+ employees and contractors at site. We are just months away from producing finished copper in Arizona, when copper is trading at an all-time high price and when there is an increased need for Made in America solutions to our energy and national security."

Progress as of the Company's last update (see Gunnison news release dated June 9th) includes:

• Stacking and acid curing of mineralized material has commenced (Figure 1).
• Material continues to be stockpiled in advance of the completion of the leach pads (Figure 2).
• Leach pad Phase-2 is complete.
• Phase-3 leach pad is complete and conveyors constructed.

Since the Company's last update, the Company is pleased to report that JCM construction activities continue to progress as planned. The overflow pond construction has been completed ahead of first acid irrigation. The pipelines from the leach pads to the SX/EW plant are complete, and Phase-1 pad leaching has started, with first copper cathode from Run-of-mine (ROM) oxide production using conventional leach technology scheduled for September. First copper using Nuton technology is expected before the end of the year.

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 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.

For additional information on the Gunnison Project, including the PEA and mineral resource estimate, please refer to the Company's technical report entitled "Gunnison Project NI 43-101 Technical Report Preliminary Economic Assessment" dated effective November 1, 2024 and available on SEDAR+ at www.sedarplus.ca.

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 technologies and capability. Nuton has the potential to economically unlock copper from hard-to-leach ores, including primary sulfides and, in doing so, increase domestic production of critical minerals to support the energy transition. Nuton technologies can achieve market-leading recovery rates and boost copper production in new, ongoing and historical operations, increasing resource utilization and maximizing value.

With significantly lower energy and water needs than conventional concentrating and smelting, and the ability to produce copper cathode at the mine site, Nuton offers a reliable source of domestically produced copper, with a short mine-to-metal supply chain and the ambition to set industry-leading ESG credentials.

One of the key differentiators of Nuton is the ambition to produce the world's lightest environmental 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.

Phoenix, Arizona--(Newsfile Corp. - June 17, 2025) - Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) ("Gunnison" or the "Company") is pleased to provide an update on the high-value-add ("HVA") work programs at the Gunnison Copper Project ('Project') in southeast Arizona. All dollar amounts in this press release are in United States dollars.

"We are excited the HVA programs are underway, progressing on-time and under-budget, with numerous catalysts in the next several months," states Roland Goodgame, Gunnison SVP of Business Development. He adds, "the HVA programs have the potential to enhance the Gunnison Copper Project's robust economics and will provide valuable guidance for the up-coming PFS. We are aggressively moving the Gunnison Open Pit forward, which is one of the largest copper projects in development in America. We are equally excited about our soon-to-be-producing Johnson Camp Mine, all at a pivotal time for copper in Arizona meeting the need for domestic copper production."

In preparation for the Gunnison Copper Project pre-feasibility study ("PFS") the Company commenced what it identified as the high-value-add work programs (See press release dated April 14^th, 2025). These programs are expected to take 3-6 months to complete, which are on schedule and under budget. (See Figure-1). An update on the HVA work programs are below:

• Gravel By-Product Revenue - An experienced consulting firm has been engaged to investigate the viability of marketing gravel and limestone. Their geologists and engineers are currently reviewing the data that has been supplied. Once the data review is complete, they will advise the Company on the economic viability of the approximately 760 million tons of alluvial gravel that is expected to be mined during the mine life. The mining of the alluvial gravel is already fully costed as waste in the Gunnison Copper Project Preliminary Economic Assessment ("PEA"). However, it is anticipated that some of this material has commercial value. 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 requires minimal further processing*.

• Limestone By-Product Revenue - As mentioned above, the experienced consulting firm is investigating the viability of marketing gravel and limestone by-products from the Gunnison open pit. The geologists are currently reviewing the existing drill core in preparation for sampling and analysis (see Figures 2A to 2D). Once the analysis is complete, they will advise on the economic viability of the 85million tons of Escabrosa limestone that is expected to be mined as waste in the Gunnison open pit (additional limestone occurs in the overlying Horquilla formation). The mining cost of this material is already included in the PEA so any value from the sale of this by-product should be highly accretive. For example, 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 requires minimal further processing*.

• Mineralized Material Sorting - Drilling of all 3 holes totaling 3,899 feet targeting oxide mineralization in the Martin and Abrigo formations were competed in May. Drilling costs were cheaper than budgeted due to high drill production rates. The holes are currently being scanned in Salt Lake City using LIBS (Laser-Induced Breakdown Spectroscopy). Following LIBS scanning, the core will be sent for assaying and extensive mineralogical testing. The mineralized material sorting plan has been completed, and testing is scheduled for the weeks of August 4^th and 25^th. (See Figure-3 for results of early test work completed in 2024)

• Permitting - Gunnison's prior permitting and community track record is excellent. There is no federal permitting required. The Gunnison Copper Project is permitted today for in-situ recovery; however, amendments are needed. Trinity Consultants (Air Quality Permit) and Clear Creek (APP) have been engaged and have produced drafts for the permitting process.

• 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). As an example, one of the recent HVA drill holes intersected coarse grained copper sulfide mineralization in quartz veins related to porphyry dyke intrusions at depth in hole NSM-16 (see Figure-4). This hole is yet to be assayed.

Figure-2A to 2D Limestone Core. The four images above show limestone material in core from Hole NSD-41 at the Gunnison project. Figure 2A shows the white limestone starting at ~395 below surface, immediately below the base of the alluvium (gravel) overburden. Figure 2B shows the limestone at 575 feet. Figure 2C shows the limestone at 775 feet and Figure 2D at 975 feet, demonstrating an extensive thickens of limestone. These drill core samples have not yet been assayed for mineral content and the Company will provide disclosure of assay data when available.

Figure-3. Red-brown and green-blue copper oxide mineralization shown in drill core above is highlighted by the green boxes. This mineralized material is confined to discrete mineralized intervals between un-mineralized waste. Material sorting has the potential to separate the visibly distinct mineralized material from the waste. Samples sent to a material sorting laboratory in 2024 (bottom images) showed 100% separation of mineralized material from waste material simply based on the presence of green coloration (copper oxide) in the sample. The HVA drilling program is collecting a number of bulk samples for further testing.

* This does not include the costs of making this material marketable, and there is no guarantee it can be made marketable.

All dill holes have been drilled using diamond drill rigs to generate PQ sized core and assays are underway for all holes. All samples are prepared from manually split or sawn PQ core sections on site in Arizona. Split drill core samples are then sent to independent laboratory Skyline Assayers & Laboratories in Tucson, Arizona for Total Copper and Sequential Copper analyses. Standards, blanks, and duplicate assays are included at regular intervals in each sample batch submitted from the field as part of an ongoing Quality Assurance/Quality Control Program. Pulps and sample rejects are stored by Gunnison for future reference.

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.
