Blast Message

"Hello, this is Allen Palmiere, President and Chief Executive Officer of Gold Resource Corporation. I’m reaching out personally regarding our upcoming Special Shareholder Meeting on July 2nd.

We recently mailed you proxy materials for this upcoming meeting, where you will be asked to vote on our proposed merger with Goldgroup Mining Inc. By blending our operations at the Don David Gold Mine with Goldgroup’s producing assets, we will significantly reduce single-asset dependency and expand our exploration footprint, which will potentially enhance cash generation. We believe this will create a stronger, silver-focused vehicle positioned to capture significant market visibility and institutional support. This is a transformative milestone for our company, creating a leading, multi-mine precious metals producer with assets across Mexico and the U.S. Please read the proxy statement we mailed to you for a full discussion of the background, benefits, and potential risks of the proposed merger.

Our Board of Directors has unanimously determined that this transaction is in the best interests of stockholders and strongly recommends that you vote “FOR” the merger.

Your vote is important. Every vote counts regardless of the number of shares you hold, and you can cast your vote quickly and easily by calling our proxy solicitor, Laurel Hill Advisory Group, at 888-742-1305, where a representative is available to assist you.

Thank you for your time, your continued support, and your investment in Gold Resource Corporation."
