Cascadero Copper Announces Sale of Cascadero Minerals Corporation

Cascadero Copper Corporation has signed a share purchase and sale agreement dated September 1, 2026, to sell all issued and outstanding shares of Cascadero Minerals Corporation, or CMC. The buyer is Lumina Copper Corp., described as a wholly-owned affiliate of First Quantum Minerals Ltd. Cascadero Copper is selling its 70% interest in CMC, while director Nelson Borch is selling his 30% interest.

Total consideration for the transaction is up to US$19,000,000, structured as follows:

• US$15,000,000 in upfront cash, subject to adjustments.
• Up to US$4,000,000 in deferred cash.

The deferred consideration is split into two tranches:

• US$2,000,000 payable within 10 business days after Lumina or an affiliate makes a final investment decision to construct the Taca Taca project.
• US$2,000,000 payable within 10 business days after US$100,000,000 has been incurred for construction of the Taca Taca project.

CMC, through Salta Geothermal S.A. and Arisaru Resources S.A., owns or will own mining rights in Salta Province, Argentina. The release lists La Sarita I, La Sarita II, La Sarita Sur II, Sarita Este at 49%, Francisco I and II at 50%, Desierto I and II at 33.3%, Sarita Sur, Amarillo, Viejo Campo, Demasia - La Sarita I and Demasia - Sarita Sur. While the summary describes the sale as including the Taca Taca project, the full release ties deferred payments to Taca Taca milestones while the enumerated transferred rights do not explicitly include Taca Taca.

At closing, Lumina will pay about US$925,000 on behalf of Cascadero Copper to an arm's length third party, which will adjust the upfront consideration. Cascadero Copper will also assume about CAD 163,631 of debt owed by CMC to director Nelson Borch. Before closing, Cascadero Minerals S.A. will become a direct subsidiary of Cascadero Copper, and Cascadero Copper will retain the seven Taron Cesium project properties: El Oculto, Centauro, Cerro Lari I, Cerro Lari II, Las Burras, Incahuasi and Santa Rosa.

The transaction requires at least 66 2/3% shareholder approval and TSXV approval as a Reviewable Disposition. Lumina has voting and support agreements covering about 47.9% of Cascadero Copper shares on a partially diluted basis. Board approval was unanimous. Paradigm Capital Inc. acted as financial advisor and will receive an advisory fee of 1% of transaction proceeds upon closing. Post-closing, the company intends to focus on the Taron Cesium project and references an April 22, 2024 preliminary economic assessment.

The transaction carries a consideration value that is large relative to the company’s current market capitalization. At a share price of CAD 0.01, Cascadero Copper’s market cap stands at approximately CAD 3.0 million. The company holds a 70% gross share of the US$15,000,000 upfront payment, which amounts to roughly US$10,500,000 before a disclosed US$925,000 third-party payment adjustment.

The company’s 70% share of the deferred consideration is valued at up to US$2,800,000, bringing the total potential gross share to approximately US$13,300,000 before deductions. This financial injection is critical given the company’s prior-period context. Financial statements from Q2 2026, which were not part of today’s release, indicate that Cascadero Copper was severely constrained, holding only CAD 21,117 in cash and facing a working capital deficiency of CAD 923,608. Total liabilities stood at CAD 1,405,797 with negative equity of CAD 923,608, leading the MD&A to state that the financial statements were prepared on a going concern basis. If the transaction closes, the upfront cash is expected to resolve this immediate pressure and provide capital for the Taron Cesium project.

The materiality of the deal is conditional, as the transaction is signed but not yet closed. It requires approval from 66 2/3% of shareholders and the TSXV. Support agreements currently cover only 47.9% of shares on a partially diluted basis, meaning approval is not assured. Furthermore, the deferred consideration is not guaranteed, as it depends on future construction decisions regarding the Taca Taca project by Lumina or First Quantum. No prior historical news was provided, making it impossible to assess whether the transaction was previously signaled or met prior guidance.

Net proceeds will be lower than the headline US$19,000,000 due to the US$925,000 third-party payment, a CAD 163,631 debt assumption, and a 1% advisory fee. Despite these adjustments, the expected upfront cash is likely a multiple of the current market capitalization.

Cascadero Copper Corporation (TSXV: CCD) is a pre-revenue junior explorer focused on Argentina. Prior to this transaction, its main assets were held through CMC in Salta Province, Argentina, plus the Taron Cesium project. Following the sale, the retained flagship project is Taron Cesium.

Taron is located in Salta Province, northwestern Argentina, approximately 160 km northwest of Salta city, at an elevation of roughly 4,250 metres above sea level. The project comprises five contiguous tenures totaling about 8,179 hectares. No mineral resources or reserves have been estimated for the property.

In 2017, drilling comprised 35 HQ diamond drill holes totaling 2,595.25 metres. Reported significant intervals used a 1,000 ppm Cs cut-off; for example, TAR2017-26 returned 12 m at 7,422 ppm Cs.

The company also had or has earn-in or joint venture arrangements involving Golden Minerals at Sarita Este and Desierto, and Elevado Resources at El Oculto. The release indicates the CMC sale includes Sarita Este and Desierto, so these arrangements may be affected, though the release does not provide that detail.
