(the "Company" and its subsidiaries) signed a definitive mining concession purchase agreement (the "Agreement", including Annex 1) for the acquisition of 3,742 hectares of exploitation-level mining concessions in the San Juan mining district in Chile from Cobalt Chile SpA, an unrelated party, as further outlined in item 2.01 that follows.

The majority of the mining concessions are located north of the Company's existing mining concessions, however, a portion of them lie adjacent to the Company's existing mining concessions.

Per the terms of the issuance agreement, the issued stock is restricted and subject to a "lockup" whereby only 1.5 million cumulative shares of the stock may be sold under a valid securities law exemption in each successive year after the transaction, through to the third anniversary of the transaction, at which time any remaining shares held from the issuance may be sold under an appropriate exemption from securities laws.

Section 5.02 Indemnification of Seller.

The Parent hereby agrees to indemnify, defend and hold harmless to the fullest extent permitted by applicable law the Seller and its Affiliates and each of their respective members, managers, partners, directors, officers, employees, stockholders, attorneys and agents and permitted assignees (each a "Seller Indemnified Party"), against and in respect of any and all Losses incurred or sustained by any Seller Indemnified Party as a result of or in connection with any breach, inaccuracy or nonfulfillment or the alleged breach, inaccuracy or nonfulfillment of any of the representations, warranties, covenants and agreements of the Buyer contained herein or in any of the Transaction Documents.

Section 5.03 Indemnification Procedures. The Person making a claim under this is referred to as the "Indemnified Party" and the Party against whom such claims are asserted under this ‎Article V is referred to as the "Indemnifying Party."

Section 5.04 Procedure. The following shall apply with respect to all indemnification claims pursuant to this ‎Article V:

(a)

Third-Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any Action made or brought by any Person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a Representative of the foregoing (a "Third-Party Claim") against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party shall give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after receipt of such notice of such Third-Party Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Third-Party Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party, to assume the defense of any Third-Party Claim at the Indemnifying Party's expense and by the Indemnifying Party's own counsel, and the Indemnified Party shall cooperate in good faith in such defense. In the event that the Indemnifying Party assumes the defense of any Third-Party Claim, subject to ‎Section 5.04(b), it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third-Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party shall have the right to participate in the defense of any Third-Party Claim with counsel selected by it subject to the Indemnifying Party's right to control the defense thereof, provided that the fees and disbursements of such counsel shall be at the expense of the Indemnified Party.

	(b)	Settlement of Third-Party Claims. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into settlement of any Third-Party Claim without the prior written consent of the Indemnified Party, except as provided in this ‎Section 5.04(b). If a firm offer is made to settle a Third-Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third-Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party consents to such firm offer the Indemnifying Party may settle the Third-Party Claim upon the terms set forth in such firm offer to settle such Third-Party Claim. If the Indemnified Party objects to such offer, or does not provide a response to such firm offer within ten days after its receipt of such notice (in which case the Indemnified Party shall be deemed to not have consented to such offer), the Indemnified Party shall thereafter assume the defense of such Third-Party Claim and shall continue to contest or defend such Third-Party Claim and in such event the maximum liability of the Indemnifying Party as to such Third-Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party has assumed the defense pursuant to this ‎Section 5.04(b), the Indemnified Party shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).
	(c)	Direct Claims. Any Action by an Indemnified Party on account of a Loss which does not result from a Third-Party Claim (a "Direct Claim") shall be asserted by the Indemnified Party giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have thirty (30) calendar days after its receipt of such notice to respond in writing to such Direct Claim. The Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party's investigation by giving such information and assistance as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such thirty (30) calendar day period, the Indemnifying Party shall be deemed to have accepted liability for such claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.
	(d)	Cooperation. Upon a reasonable request made by the Indemnifying Party, each Indemnified Party seeking indemnification hereunder in respect of any Direct Claim, hereby agrees to consult with the Indemnifying Party and act reasonably to take actions reasonably requested by the Indemnifying Party in order to attempt to reduce the amount of Losses in respect of such Direct Claim. Any costs or expenses associated with taking such actions shall be included as Losses hereunder.

Section 5.05 Payments. Any indemnification required by this ‎Article V for costs, disbursements or expenses of any Indemnified Party in connection with investigating, preparing to defend or defending any Action shall be made by periodic payments by the Indemnifying Party to each Indemnified Party during the course of the investigation or defense, as and when bills are received or costs, disbursements or expenses are incurred. Provided, however, that if a final and non-appealable judgment determines that the Indemnifying Party's liability is less than the amounts paid on account of such indemnification, the Indemnified Party shall promptly reimburse the Indemnifying Party the excess amount paid, within thirty (30) calendar days from the date of judgment's notification.

Section 5.06 Insurance. Any indemnification payments hereunder shall take into account any insurance proceeds or other third-party reimbursement actually received.

Section 5.07 Time Limit. The obligations of the Seller and the Buyer under ‎Section 5.01 and ‎Section 5.02 shall expire two (2) years from the Closing Date, except with respect to (i) an indemnification claim asserted in accordance with the provisions of this ‎Article V which remains unresolved, for which the obligation to indemnify shall continue until such claim is resolved; and (ii) resolved claims for which payment has not yet been paid to the Indemnified Party.

Section 5.08 Limitations; Acknowledgement. Notwithstanding anything to the contrary in this ‎Article V, neither Party shall be obligated to indemnify any Persons for any Losses in excess of the total fair market value of the Shares as of the Closing Date, as determined based on the closing trading price of the Common Stock as of the date immediately preceding the Closing Date (the "Cap"). For the avoidance of doubt, Cap shall apply (i) as to all of the Buyer Indemnified Parties collectively, and the Seller shall not be subject to the Cap with respect to each individual Buyer Indemnified Party; and (ii) as to all of the Seller Indemnified Parties collectively, and the Buyer shall not be obligated to satisfy the Cap, with respect to each individual Seller Indemnified Party. The Parties acknowledge and agree that the provisions of this ‎Article V are material to this Agreement and the Transactions and that it is the intent of the Parties that this ‎Article V be enforced specifically in accordance with its terms.

Exhibit 99.1

CHILEAN COBALT CORP. ANNOUNCES ACQUISITION OF AN ADDITIONAL 3,742

HECTARES IN THE SAN JUAN DISTRICT

BERWYN, PA - (September 15, 2025) - Chilean Cobalt Corp. (OTCQB: COBA) ("Chilean Cobalt" or the "Company") is pleased to announce it has finalized a definitive agreement with Cobalt Chile SpA ("Cobalt Chile"), a wholly-owned subsidiary of Fuerte Metals Corp. (TSX-Venture: FMT) ("Fuerte Metals") to acquire a 100% interest in 3,742 hectares of exploitation claims in the historic San Juan district. The acquisition includes the El Cofre copper-cobalt-gold project, as well as additional properties in the La Cobaltera project area ("Transaction"), which increases Chilean Cobalt's mining concessions in the region to a total of 6,377 hectares - up from its current 2,635 hectares.

The acquisition includes 3,742 hectares of exploitation claims, comprising approximately 372 hectares adjacent to Chilean Cobalt's existing La Cobaltera project area and the 3,370 hectare El Cofre project, located in the northeast extension of the San Juan district. The region is strategically located near excellent infrastructure, including access to roads, power, and proximity to the Port of Huasco, just 25 km away.

The additional claims near the La Cobaltera area include several historic mine sites along with multiple well-documented cobalt and copper-bearing veins ranging in width from 0.5 to 20 meters, visible from the surface down to at least 50 meters. These claims further consolidate Chilean Cobalt's presence in the brownfield segment of the district.

The El Cofre project, located along a 25 km strike of the Atacama Fault Zone, is a potential extension or geologic analogue to the broader San Juan district. Historical work on the property includes airborne geophysics, geochemical surveys, an induced polarization (IP) survey, and trenching, which have collectively identified three drill-ready targets along with several additional zones of interest.

Under the terms, Cobalt Chile SpA, a wholly-owned subsidiary of Fuerte Metals, will transfer 100% ownership of the mining concessions to Baltum Minería SpA, a wholly-owned subsidiary of Chilean Cobalt. In exchange, Cobalt Chile SpA will receive 4.5 million common shares of Chilean Cobalt and reimbursement for the 2025/26 annual patent payments for those concessions. The combination brings together two complementary portfolios focused on the redevelopment of brownfield assets and the advancement of greenfield exploration opportunities across the San Juan district.

Chilean Cobalt plans to incorporate the newly acquired claims into its next phase of exploration, scheduled to commence in the second half of 2025. The upcoming program is expected to include detailed geological mapping, trenching, and additional geophysical and IP surveys, with the goal of identifying additional drill-ready targets.

This press release does not constitute an offer or sale of, or the solicitation of an offer to buy, securities of the Company nor shall there be any sale of any securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
