Goldgroup Advances San Francisco Toward Potential Production Restart

Goldgroup Mining Inc. is moving forward with plans to potentially restart gold production at its San Francisco project in Sonora, Mexico, building on an existing mine, processing infrastructure and a substantial mineral resource base. The company is combining technical drilling, plant refurbishment and mine-planning work as it evaluates a possible return to production around the end of 2026 or during 2027.

The San Francisco project is particularly significant because it is a formerly producing operation rather than a greenfield development. Goldgroup acquired 100% ownership of the project in June 2026 and has since accelerated work intended to determine how quickly the mine could return to operations.

The company’s strategy involves using infrastructure already present at the site while updating geological information and optimizing the future mine plan. However, investors should note that a production restart remains a potential outcome rather than a guaranteed development decision.

San Francisco Project Provides Existing Mining Infrastructure

San Francisco is located in Sonora, approximately 150 kilometres north of Hermosillo. The project includes the former San Francisco and La Chicharra open pits, along with crushing equipment, heap-leach facilities, ADR gold-recovery plants, power infrastructure, roads and other supporting facilities.

According to Goldgroup, the project is fully permitted for a rapid restart of mining operations. The presence of established infrastructure could reduce the time and capital requirements normally associated with developing a new mine.

The project has historically produced significant quantities of gold. Goldgroup’s updated technical information indicates that San Francisco and La Chicharra produced approximately 1.3 million ounces of gold between 2010 and 2023 before the operation was acquired by the company.

Existing Infrastructure Could Support a Faster Restart

Goldgroup’s current plans are focused on returning idle infrastructure to operating condition rather than constructing an entirely new processing complex.

The company has engaged INPROMINE, a mining construction contractor based in Sonora, to work on the crushing and conveying systems and ADR plants. The contract is valued at approximately US$850,000 and was expected to take about 16 weeks.

The work includes reviewing, servicing, testing and commissioning equipment. Bringing these systems back into operational condition is an important step before the company can determine whether a full production restart is technically and economically practical.

Goldgroup Advances 24,000-Metre Drilling Program

Another major component of the restart strategy is a 24,000-metre diamond drilling program. Goldgroup began the program in June 2026, with the objective of improving the geological model, reducing historic drill-spacing gaps and generating information needed to optimize a future mine plan.

The company expects the drilling program to help define the areas that could be prioritized during a potential restart. The work also provides an opportunity to evaluate resource expansion targets surrounding the historical mining areas.

Goldgroup has described the drilling program as an important technical step because historical information alone may not provide sufficient detail for an optimized modern mine plan.

Resource Base Offers a Foundation for Mine Planning

The San Francisco project has a reported Measured and Indicated mineral resource of approximately 1.226 million ounces of gold, together with an additional 178,000 ounces in the Inferred category.

The company has also identified exploration targets with potential to add to the resource base. One exploration target associated with the El Llano area has been described in technical reporting as potentially containing additional gold mineralization. These quantities remain conceptual and should not be treated as mineral resources or reserves.

Importantly, mineral resources are not the same as mineral reserves. A resource estimate does not establish that the material can be economically mined. Additional engineering, mine planning, economic evaluation and other technical work are required before a definitive production decision can be made.

Potential Production Restart Targeted for 2027

Goldgroup has previously indicated that it is targeting a potential restart around the end of 2026 or early 2027. More recent project information points toward 2027 as the principal restart timeframe.

The process is expected to progress in stages. Drilling and technical work are intended to improve the mine plan, while refurbishment activities focus on preparing the processing infrastructure. Mining could then resume if the technical and economic conditions support a restart.

Goldgroup’s project information outlines potential production of approximately 50,000 to 60,000 gold-equivalent ounces annually once the operation is fully ramped up. This figure represents potential production and should not be interpreted as a confirmed production forecast.

Why the Restart Strategy Matters

Restarting a previously producing mine can offer advantages compared with building a project from the ground up. Existing roads, processing equipment, power systems and mine infrastructure may reduce development requirements and shorten the timeline to potential production.

For Goldgroup, San Francisco could therefore become an important growth asset if the restart program proceeds successfully. The company already has exposure to gold production elsewhere in Mexico, meaning a successful San Francisco restart could potentially add another operating asset to its portfolio.

Financial and Operational Considerations

Although existing infrastructure can lower development requirements, a mine restart still involves meaningful expenditure. Equipment must be inspected and refurbished, mining activities must be re-established and working capital will be required to support operations before steady-state cash generation is achieved.

Goldgroup’s project information identifies spending requirements for drilling, plant refurbishment and production working capital. Actual costs could change as technical studies, equipment inspections and mine planning progress.

Investors should therefore focus on milestones rather than assuming that the announced restart target automatically translates into production. Drill results, equipment commissioning, operating costs, mine-plan economics and financing requirements will all influence the eventual outcome.

Exploration Could Add Further Upside

San Francisco is not solely a restart story. Goldgroup believes the property has additional exploration potential beyond the historical pits.

The company has identified multiple exploration targets across its extensive concession package. The ongoing drilling program is primarily intended to support resource definition and mine planning, while future exploration could investigate areas with potential to expand the project’s mineral inventory.

If additional mineralization is successfully defined, it could potentially support a longer mine life or provide additional flexibility in future mine planning. Nevertheless, exploration targets are inherently uncertain and require further drilling before their economic significance can be established.

Goldgroup’s Broader Growth Strategy

The San Francisco restart is part of a broader growth strategy for Goldgroup. The company also has the Cerro Prieto heap-leach gold operation in Sonora and has been pursuing a business combination involving Gold Resource Corporation and its Don David gold operation in Oaxaca, along with the Back Forty project in Michigan.

This broader portfolio gives Goldgroup exposure to producing, restart and development-stage assets. Successful execution across these projects could increase the company’s production profile over time, although each asset carries its own technical, operational, permitting and financial risks.

What Investors Should Watch Next

Several milestones could determine whether San Francisco moves closer to a successful production restart.

  • Results from the 24,000-metre diamond drilling program.
  • Updated geological and resource information.
  • Progress on the optimized mine plan.
  • Completion and commissioning of crushing and conveying equipment.
  • Refurbishment and testing of the ADR plants.
  • Confirmation of mining and processing economics.
  • Funding and working-capital requirements.
  • Any formal production restart decision by Goldgroup.

These developments should provide investors with a clearer picture of the project’s potential operating profile and capital requirements.

Key Risks Behind the Restart Plan

The potential restart carries risks that investors should consider. The project has not yet established mineral reserves demonstrating economic viability for a restart. Goldgroup must also complete technical work and determine whether existing infrastructure can be returned to reliable operating condition.

Gold prices, operating costs, labour availability, energy costs, equipment performance and metallurgical results could all influence project economics. Regulatory and environmental requirements also remain important because the company will need to continue complying with applicable conditions as it works toward re-establishing production.

Consequently, the proposed 2026-2027 timeline should be viewed as a target rather than a certainty.

Conclusion

Goldgroup is advancing San Francisco with a strategy centered on leveraging an existing mine and processing complex while updating the technical foundation needed for a potential restart. The combination of a substantial reported mineral resource, existing infrastructure, new drilling and equipment refurbishment gives the project a potentially shorter path to production than a conventional greenfield development.

The next phase will be critical. Drilling results and equipment refurbishment should help determine the quality of the resource model and the practicality of restarting operations. If technical and economic conditions are favorable, Goldgroup could potentially move San Francisco toward renewed gold production in 2027.

For investors, the key consideration is that San Francisco represents restart potential, not guaranteed production. The project’s existing infrastructure provides an important advantage, but the ultimate value will depend on successful mine planning, capital management, operating performance and the economics of renewed gold production.
