Arrangement Agreement and Plan of Merger financial

"entered into an amendment (the “Amendment”) to the previously announced Arrangement Agreement and Plan of Merger"

A formal contract that sets out the detailed terms and steps for combining two companies — typically including how shares or cash will be exchanged, the timetable, and any conditions or approvals required. Think of it as both the blueprint and the rulebook for a marriage between businesses: it tells shareholders what they will receive, what must happen first, and what can stop the deal. Investors watch it closely because its terms determine changes in ownership, potential dilution or cash value, the likelihood the deal closes, and any financial risks or breakup costs.

TSX Venture Exchange financial

"subject to, among other things, the approval of the TSXV, which approval is subject to compliance with the requirements of the TSXV"

A junior stock exchange in Canada where smaller, early-stage companies list shares to raise capital and gain public visibility. Think of it as a farmers’ market for young businesses: it offers investors a chance to buy into fast-growing but higher-risk ventures, with looser listing rules and typically lower liquidity than major exchanges. It matters because performance and financing on this exchange can signal growth prospects or risk for investors.

NYSE American Listing financial

"Goldgroup will apply to list the Goldgroup Shares on the NYSE American (the “NYSE American Listing”)"

Section 3(a)(10) of the Securities Act of 1933 regulatory

"anticipated to be issued in reliance upon available exemptions from registration requirements pursuant to Section 3(a)(10) of the Securities Act of 1933"

proxy statement regulatory

"the preliminary proxy statement that the Company will file, as well as in the Annual Reports"

A proxy statement is a document companies send to shareholders ahead of a meeting that lays out the items up for a vote—like who will sit on the board, executive pay, and major corporate decisions—and provides background so shareholders can decide how to cast their votes or appoint someone to vote for them. Think of it as an agenda plus a ballot and briefing notes, important because the outcomes can change control, strategy, and value.

Item 1.01

Entry into a Material Definitive Agreement

On May 15, 2026, Gold Resource Corporation (the “Company”), Goldgroup Mining Inc., a corporation incorporated under the laws of the Province of British Columbia (“Goldgroup”), and Goldgroup Merger Sub Inc., a Colorado corporation and direct subsidiary of Goldgroup (“Purchaser Sub”), entered into an amendment (the “Amendment”) to the previously announced Arrangement Agreement and Plan of Merger, dated January 25, 2026, by and among the parties (the “Arrangement Agreement”). The Arrangement Agreement provides that, among other things and subject to the terms and conditions of the Arrangement Agreement, Purchaser Sub will merge with and into the Company, with the Company surviving and continuing as the surviving corporation as a direct, wholly owned subsidiary of Goldgroup (such transaction, the “Merger”).

The Arrangement Agreement originally contemplated that, immediately prior to the effective time of the Merger, Goldgroup would consolidate all of its issued and outstanding common shares without par value (each whole share, a “Goldgroup Share”) at a ratio of one post-consolidation Goldgroup Share for every four pre-consolidation Goldgroup Shares. Pursuant to the Amendment, the parties have agreed to replace the four-to-one consolidation ratio with a consolidation ratio to be determined jointly by Goldgroup and the Company, and approval by the TSX Venture Exchange (the “TSXV”), prior to the effective date of the Merger. The Arrangement Agreement provides, among other things, that Goldgroup will apply to list the Goldgroup Shares on the NYSE American (the “NYSE American Listing”), which listing will be completed following the closing of the Merger and is subject to Goldgroup fulfilling all the listing requirements of the NYSE American. The consolidation is being undertaken by Goldgroup in order to meet the listing requirements of the NYSE American and to facilitate the NYSE American Listing. The consolidation is subject to, among other things, the approval of the TSXV, which approval is subject to compliance with the requirements of the TSXV, including, if applicable, shareholder approval.

Additional Information

The foregoing description of the Amendment is qualified in its entirety by reference to the full text of the Amendment, a copy of which is filed hereto as Exhibit 2.1, and is incorporated into this Current Report on Form 8-K by reference. Additional information about the Merger, including a copy of the Arrangement Agreement, was previously filed by the Company in a Current Report on Form 8-K with the Securities and Exchange Commission (the “SEC”) on January 26, 2026. Copies of the agreements related to the Merger have been included to provide investors with information regarding their terms and are not intended to provide any factual information about the Company, Goldgroup, Purchaser Sub or their respective affiliates. The representations, warranties and covenants contained in the agreements have been made solely for the purposes of the agreements and as of specific dates; were made solely for the benefit of the parties to the agreements; are not intended as statements of fact to be relied upon by investors, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate; have been modified or qualified in some cases by certain confidential disclosures that were made between the parties in connection with the negotiation of the agreements, which disclosures are not reflected in the agreements themselves; may no longer be true as of a given date; and may apply standards of materiality in a way that is different from what may be viewed as material by investors. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Company, Goldgroup, Purchaser Sub or their respective affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the agreements, which subsequent information may or may not be fully reflected in the Company’s public disclosures. The agreements should not be read alone but should instead be read in conjunction with the other information regarding the Merger, the agreements related to the Merger (including the Amendment and the Arrangement Agreement), the Company, Goldgroup, Purchaser Sub, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the preliminary proxy statement that the Company will file, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings that the Company will file or furnish with the SEC.
