The inclusion represents a positive capital-markets milestone for Goldgroup as the Company advances its strategy of building a diversified precious metals mining business with established operating assets, significant exploration potential and opportunities for future growth.

The Solactive Global Silver Miners Index tracks companies operating across the global silver mining sector. Goldgroup's inclusion places the Company among a top group of international mining companies recognized within this sector-focused index.

As we continue to advance that strategy, we want to ensure that more investors understand the quality of our asset portfolio, the opportunities ahead of us and the potential we see to grow the business.
