Goldgroup Advances San Francisco Toward Potential Production Restart

Goldgroup Mining Inc. (TSXV: GORO) (NYSE American: GORO) (FSE: 55G) (" Goldgroup " or the " Company ") is pleased to provide an update on its 100%-owned San Francisco Gold Project in Sonora, Mexico which represents a potentially transformative growth opportunity for Goldgroup. The project is a large-scale, formerly producing open-pit gold operation with substantial existing resources, established infrastructure, permitted mining operations and a significant exploration package . Goldgroup is now moving the project through the critical technical and development work required to determine the optimal path toward a potential production restart. A Cornerstone Gold Asset with Exploration Potential San Francisco currently hosts Measured Mineral Resources of approximately 48.3 million tonnes grading 0.37 grams per tonne ("g/t") gold and containing approximately 582,000 ounces of gold and Indicated Mineral Resources of approximately 56.8 million tonnes grading 0.35 g/t gold and containing approximately 645,000 ounces of gold. Combined Measured and Indicated Mineral Resources contain approximately 1.23 million ounces of gold. In addition, San Francisco hosts Inferred Mineral Resources of approximately 17.3 million tonnes grading 0.32 g/t gold and containing approximately 178,000 ounces of gold. The Mineral Resource estimate has an effective date of April 30, 2026. For additional information regarding the Mineral Resource estimate, including the key assumptions, parameters and methods used, please refer to the NI 43-101 technical report entitled "Technical Report for the San Francisco Project, Sonora, Mexico," with an effective date of April 30, 2026, available under the Company's profile on SEDAR+. Importantly, the existing resource is only part of the opportunity. The project encompasses 46,932 hectares of mining concessions , which includes the historic San Francisco and La Chicharra open pits as well as several areas with potential for resource expansion and new discoveries. One of the most compelling exploration opportunities is the El Llano zone , immediately contiguous to the San Francisco pit and target for drilling from surface. "Scattered exploration drilling east of the San Francisco Pit, in what has been termed the El LIano exploration target area, has indicated that the mineralization identified and mined in the pit could potentially continue to the east towards Mexican State Highway 15 (Pan American Highway), While the drilling at this time is too widely spaced to infer continuity between the individual mineralized intersections identified in the drill holes, the general intersections are similar to those mined in the San Francisco Pit and generally lie in the easterly strike direction of mineralization located in the San Francisco Pit. Therefore, Micon's QPs believe that the El Llano exploration target area has the potential to host a mineralized zone similar to that found in the San Francisco Pit." ("Technical Report for the San Francisco Project, Sonora, Mexico," with an effective date of April 30, 2026, available under the Company's profile on SEDAR+) The Company's current technical report identifies an exploration target at El Llano of possibly 40 million tonnes to 78 million tonnes with grades ranging from 0.38 to 0.61 g/t Au . The potential quantity and grade of the El Llano exploration target are conceptual in nature. There has been insufficient exploration to define a Mineral Resource at El Llano, and it is uncertain whether further exploration will result in the target being delineated as a Mineral Resource. The project also includes the North Pit resource providing Goldgroup with multiple opportunities to potentially expand the resource and extend the mine life. Additionally, a geological review of the entire land package is also being conducted to identify additional exploration targets near the existing mine. 26,000-Metre Drill Progra...
