Gunnison Copper Corp. (TSX: GCU) put out the update on 5 Oct 2026. It expects to start trading under the ticker GUNN in late October 2026, but only after SEC filings and final approvals are done. The Gunnison Copper NYSE listing would add a second market for investors, while the Toronto Stock Exchange listing stays in place. The Phoenix-based producer holds all its mining and development assets in Arizona.
Gunnison points to record copper prices, and it supplies the US defence sector and Amazon Web Services today. That mix puts the Company in the conversation around US copper supply chain stocks. Investors get a producing base and a larger development Project in one story.
Gunnison Copper NYSE Listing: Pre-Clearance and ADR Plan
Gunnison intends to set up a Level II American Depositary Receipt (ADR) programme. Each ADR would represent 35 common shares. US investors would buy ADRs priced in US dollars under the ticker GUNN. Toronto trading continues under GCU, so the Gunnison Copper NYSE listing adds a route without replacing one.
Gunnison notes that pre-clearance is not final listing approval. The plan still needs SEC registration to take effect and NYSE American requirements to be met. Gunnison cautions that the listing could change in terms or timing, and it may not proceed at all.
| Item | Detail |
| NYSE American ticker | GUNN |
| TSX ticker | GCU |
| ADR structure | Level II, 35 common shares per ADR |
| Expected trading | Late October 2026 |
| Status | Pre-clearance only, not final approval |
US Copper Supply Chain Stocks: Defence and Data Centre Demand
Gunnison supplies copper to the US defence sector and belongs to the Defence Industrial Base Consortium. Amazon Web Services buys copper directly from Gunnison for use in building data centres. That ties Gunnison’s output to defence and cloud infrastructure demand, a useful angle on US copper supply chain stocks.
Gunnison turns the copper from Johnson Camp into finished cathode at the Arizona site, so nothing goes abroad for smelting or refining. Gunnison is planning the Gunnison Project the same way. The result is a supply chain that stays in the United States and does not rely on overseas processing.
Production Base and Growth Pipeline
Johnson Camp Mine Capacity
Gunnison’s producing asset, Johnson Camp Mine in Arizona, can make up to 25 million pounds of finished copper cathode each year. Nuton LLC, a Rio Tinto Venture, provides all of the funding. CEO Craig Hallworth pointed to speed: “We brought Johnson Camp from construction decision to production in under 18 months.”
Gunnison Project Potential
Gunnison’s preliminary economic assessment (PEA), completed in March 2026, points to average production of 174 million pounds a year across the Project’s first 15 years. Combined with Johnson Camp, output could reach nearly eight times Johnson Camp’s nameplate capacity if the Project proceeds. As an early study that draws partly on Inferred Mineral Resources, the PEA offers no guarantee of the outcomes.
| Measure | Detail |
| Johnson Camp capacity | Up to 25 million pounds a year |
| Average Project output | 174 million pounds a year |
| NPV8% | US$2 billion |
| IRR | 23% |
| Payback period | 3.9 years |
| Design | Open pit, heap leach, SX/EW refinery |
Industry Outlook for NYSE American Copper Companies
Gunnison is leaning on record copper prices, and it links the metal to AI, electrification and defence. CEO Craig Hallworth said, “Copper connects some of America’s most powerful investment themes: artificial intelligence, electrification, and national defence.” Within the copper mining sector, that message frames Gunnison as a growth story among US copper supply chain stocks.
If approved, Gunnison would sit among NYSE American copper companies. The listing would give American investors a US dollar route into its growth.

Future Direction and Impact on Gunnison Copper’s Production Scale
Gunnison now moves through SEC registration and NYSE American approval steps for the Gunnison Copper NYSE listing. Gunnison has promised to share more news as the listing process moves ahead. If it completes, US investors would find it easier to back the Company’s growth plans.
Gunnison must still develop the Gunnison Project to deliver the PEA outputs. Within the copper mining sector, that step would decide whether output scales beyond Johnson Camp. Readers following NYSE American copper companies and US copper supply chain stocks should watch both milestones.
