Goldgroup closes San Francisco Gold Mine acquisition for 100% stake

Vancouver, British Columbia--(Newsfile Corp. - June 15, 2026) - Goldgroup Mining Inc. (TSXV: GGA) (OTCQX: GGAZF) (FSE: 55G0) (" Goldgroup " or the " Company ") is pleased to announce that it has received approval from the TSX Venture Exchange (" TSXV ") and has completed its acquisition of all of the issued and outstanding Series "A" shares in the fixed capital and all the issued and outstanding Series "B" shares in the variable capital (collectively the " Molimentales Shares ") of Molimentales del Noroeste, S.A. de C.V. (" Molimentales ") through a Concurso Mercantil process (restructuring proceeding equivalent to Chapter 11 in the United States). As announced on December 24, 2025, Goldgroup received approval from the Second District Court for Commercial Bankruptcy Matters (the " Mexican Court ") to the plan of arrangement (the " Plan of Arrangement ") the Company filed with the Mexican Court under the Concurso Mercantil process. The judgement issued by the Mexican Court on December 23, 2025 in favour of Goldgroup's Plan of Arrangement completed the bankruptcy and restructuring of Molimentales.

Molimentales' primary asset is the formerly producing San Francisco Mine concessions, located in Sonora State, Mexico. The structure of the Plan of Arrangement allowed Goldgroup to receive ownership of Molimentales, the San Francisco Mine and its associated assets, including mining concessions, processing plants, and related infrastructure, free and clear of all liens and liabilities. The San Francisco project is fully permitted for a rapid restart of mining operations and is comprised of two open pits together with heap leach processing facilities and associated infrastructure.

It is a robust project with significant gold resources and strong upside in Sonora, Mexico and positions Goldgroup with an extraordinary growth profile. Ralph Shearing, CEO, commented, "Closing the San Francisco acquisition is a major milestone for the Company. We intend to move quickly with infill drilling to tighten historic drill spacing, optimize the mine plan, and advance the project toward a potential restart of mining operations and gold production in late 2026 or early 2027.

The San Francisco Project has a strong foundation, with current Measured and Indicated resources of 1.226 million ounces of gold and an additional 178,000 ounces in the Inferred category as recently published in a NI 43-101 Technical Report dated May 1, 2026 1 . This Technical Report also highlights compelling exploration targets with the potential to add meaningful scale." Together with the Company's producing Cerro Prieto heap leach gold mine in Sonora, the San Francisco project is expected to position Goldgroup on a fast-track growth path. In addition, the Company is advancing the proposed business combination with Gold Resource Corporation which holds a 100% interest in the producing Don David gold mine in Oaxaca, Mexico as well as the Back Forty gold/silver development project in Michigan, USA.

Successful execution of this transaction could be potentially transformative to the Company. About the San Francisco Mine The San Francisco Mine, historically one of the significant gold producers in Sonora, Mexico, has substantial existing infrastructure and potential for future exploration, development, expansion and production. Securing control of this asset is aligned with Goldgroup's vision of becoming a leading Mexican-focused mining company with operational expertise and a strong commitment to responsible mining practices.

The San Francisco Mine is a large-scale, formerly producing open pit gold mine. The San Francisco Project encompasses 13 concessions totaling 33,667 hectares plus 13,284 hectares of regional concessions in the north central portion of the state of Sonora, Mexico, approximately 150 kilometers north of the state capital, Hermosillo. The operation is comprised of two previously producing open pits (San Francisco and La Chicharra), together with heap leach processing facilities and associated infrastructure located close to the San Francisco pit.

The Company's San Francisco Mine has the following royalty obligations owed to SA Targeted Investing Corp., a subsidiary of Royal Gold Inc. ("Royal Gold"): Gold Delivery: Commencing 5 (five) business days after restart of operations, and every month thereafter, deliver 75 gold ounces per month for a period of 20 months: Net Smelter Royalty: the Company will pay to Royal Gold a 1% NSR on each of the following mining concessions: San Francisco, Patricia, Norma, La Pima, Dulce, and San Judas. The NSR will commence once the Gold Delivery obligation is complete. As part of the acquisition, the Company acquired 60.24% of the debts owed to certain creditors as recognized by the Mexican Court for $8,971,000 of which $496,000 remains to be paid.

Under the terms of the Plan of Arrangement, the Company has agreed to pay $2,566,000 in three equal installments in December 2026, 2027 and 2028 to the remaining creditors holding 39.76% of the recognized debt, $1,150,000 in December 2026 to the secured creditors, in addition to all outstanding mining concession fees (including penalties and interest), taxes, fees owed to the National Water Commission, supplier debts and certain expenses related to the Concurso Mercantil proceedings currently estimated at approximately $8,900,000. The Company is currently negotiating to reduce some of these payables and expects to settle same for a lower overall balance. Some of the payments described above are facilitated through the Company acquiring the Molimentales Shares by paying the owners of the Molimentales Shares MXN$100,000 and capitalizing Molimentales with MXN$99,900,000 for a total of MXN$100,000,000. 1 The technical report by Micon International is entitled, "NI 43-101 Technical Report for the San Francisco Project, Sonora, Mexico" with a report date of May 1, 2026 and an effective date of April 30, 2026.
