GOLDGROUP ACCELERATES GROWTH STRATEGY FOLLOWING TRANSFORMATIONAL MERGER; COMPANY ADVANCES MULTI-ASSET DRILL PROGRAMS, MINE DEVELOPMENT AND EXPANSION PLANS

Goldgroup Mining Inc. has provided shareholders with a corporate update following the successful merger with Gold Resource Corp., marking the beginning of an exciting new chapter as the company executes its strategy to build a leading intermediate precious metal producer.

"Our integration is progressing well, and we are hitting the ground running," said Allen Palmiere, chief executive officer. "With multiple producing operations, an aggressive exploration program, a robust development pipeline and a strong balance sheet, we believe Goldgroup is exceptionally well positioned to create long-term value for our shareholders."

The company has launched its new corporate website, reflecting the combined organization and its expanded portfolio of producing mines, development projects and exploration assets. Investors can also access the company's latest corporate presentation through the website.

Aggressive exploration and development programs driving future growth

Goldgroup continues to invest heavily in exploration with the objective of expanding resources, extending mine life and identifying new high-value discoveries across its portfolio.

At the 100-per-cent-owned Don David mine in Oaxaca, Mexico, the company has completed more than 23,000 metres of drilling year to date, one of its largest drilling campaigns in recent years. While much of the program is focused on upgrading existing resources, a significant portion is targeting resource expansion with the goal of increasing the mine's long-term production profile.

The company currently has six underground drill rigs and one surface drill operating at Don David, reflecting the strategic importance of this asset.

In addition, drilling is expected to commence this quarter at the highly prospective Margaritas target, where historic exploration has identified epithermal veins containing exceptionally high silver grades. The company believes Margaritas represents an exciting exploration opportunity with the potential to add meaningful high-grade mineralization to the Don David district.

Advancing multiple growth assets

At the formerly producing San Francisco gold project, three drill rigs continue work on a 24,000-metre diamond drilling program designed to refine and confirm the geological model and support future mine planning as the company evaluates a potential restart of production at the end of the year. The 100-per-cent-owned San Francisco project is fully permitted for a rapid restart of mining operations and is composed 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 terms of optimized development and multiple, large-scale exploration targets.

At the 100-per-cent-owned Cerro Prieto, Goldgroup has deployed three drill rigs, including two focused on resource expansion and one conducting confirmatory drilling, to support the development of an updated mineral resource.

Back Forty feasibility study under way

The company is also advancing the Back Forty project in Michigan's Upper Peninsula, where work on a comprehensive feasibility study commenced in May under the leadership of SLR Engineering.

The 100-per-cent-owned Back Forty remains one of GoldGroup's most attractive long-term development assets, building upon the positive preliminary economic assessment completed in 2023. The feasibility study represents another important milestone as the company advances the project toward potential development.

Delivering operational performance

Operations at the Don David mine continue to perform well and in line with management's expectations, providing a solid operational foundation for the combined company.

The company will also continue to work on unlocking the significant additional value at Cerro Prieto, where management sees opportunities to increase production, improve operating efficiencies and enhance cash flow generation.

Positioned for the next stage of growth

With producing assets, a robust pipeline of development projects, an active exploration program, financial resources to execute its business plan and an experienced operating team, Goldgroup believes it is well positioned to execute its long-term strategy.

Management remains focused on creating a premier intermediate precious metal company through disciplined organic growth, resource expansion, operational excellence and value-enhancing acquisition opportunities.

"We are building a company with multiple avenues for growth," added chief executive officer Allen Palmiere. "Our priorities are clear: grow our resource base, optimize our operations, advance our development projects, and continue pursuing opportunities that strengthen our portfolio and create sustainable shareholder value."

Recent market activity

When an index provider adds or removes a stock during a rebalance (such as Russell's reconstitution), index-tracking passive funds are required to adjust their portfolios accordingly to maintain accurate tracking alignment. This temporary, short-term occurrence accounts for much of the recent market activity in Goldgroup.
