Gunnison Copper Eliminates Nebari Debt and Achieves Major Balance Sheet Milestone
Balance Sheet Cleaned and AWS Partnership Secured as Gunnison Transitions to Debt-Free Producer
The most recent news release (January 20, 2026) announces the full elimination of all secured debt owed to Nebari Natural Resources Credit Fund I LP. The company reduced its outstanding principal from US$15.0 million to zero through a combination of cash repayments ($7.3 million non-convertible portion) and equity conversions ($5.25 million convertible portion). This follows the milestone announcement on January 15, 2026, where the company entered a collaboration with Rio Tinto’s Nuton and Amazon Web Services (AWS). This partnership involves AWS using Gunnison’s "Nuton" copper in its U.S. data centers and providing cloud analytics to optimize the bioleaching technology at the Johnson Camp mine.
The impact of the January 2026 news is transformative for the company’s risk profile. - Financial De-risking: Eliminating $15M in secured debt removes the immediate threat of foreclosure and reduces high-interest financing expenses that were previously draining cash. - Validation: The AWS/Rio Tinto collaboration provides third-party validation from two of the world’s largest corporations. This is not just a technical trial; it is a commercial integration into the AWS supply chain, potentially securing a premium buyer for "low-carbon" copper. - Milestone Execution: Management has successfully followed through on the debt retirement plan outlined in March 2025. This builds significant credibility for future capital raises required for the flagship Gunnison Project. - Balance Sheet Strengthening: While the company had negative equity of $60.3M as of Sept 30, 2025, the conversion of debt to equity and the cleaning of the balance sheet significantly improves the enterprise's ability to attract institutional investment.
Gunnison Copper Corp. (formerly Excelsior Mining) operates in Arizona, a top-tier mining jurisdiction. - Flagship Project: The Gunnison Copper Project is a development-stage asset targeting 170 million lbs of copper annually starting in 2030 via open-pit mining and heap leaching. - Secondary Asset: The Johnson Camp Mine (JCM) is a producing asset (restarted Aug 2025) with a 25 million lb/year capacity. It serves as a proof-of-concept for Nuton bioleaching technology. - Resource: The flagship has a Measured & Indicated resource of 832 million tons at 0.31% Cu.
