Gold Resource Corporation Announces Special Shareholder Meeting to Vote on Strategic Merger With Goldgroup MiningJune 5, 2026 7:00 AM
Business Wire With Proxy Materials Officially Being Mailed, the Board Urges Shareholders to Vote “FOR” the Milestone Deal That Will Combine Core Assets and Drive Long-Term Shareholder Value Gold Resource Corporation (NYSE American: GORO) (the “Company,” “we,” “our,” or “GRC”) today announced updates regarding our upcoming Special Meeting of Shareholders (the “Special Meeting”) scheduled for July 2, 2026. The definitive proxy statement has been filed with the Securities and Exchange Commission (the “SEC”), and mailing has been completed to shareholders of record as of May 26, 2026. The Goldgroup Merger: Unlocking Shareholder Value Following the finalization of the definitive transaction documentation, the Company is moving into the final approval phase of its strategic combination. Under the terms of the Arrangement Agreement and Plan of Merger dated January 25, 2026, as amended on May 15, 2026, the Company will combine with Goldgroup Mining Inc. (TSX-V: GGA; OTC: GGAZF) (“Goldgroup”) via a reverse triangular merger with Goldgroup Merger Sub, Inc., a wholly owned subsidiary of Goldgroup (the “Merger”). Management believes that the proposed Merger represents a net benefit for the Company’s shareholders: Direct Share Exchange: GRC stockholders will receive 1.4476 common shares of Goldgroup for each share of GRC common stock they own (subject to adjustment for a share consolidation to be completed by Goldgroup at a ratio to be determined jointly by Goldgroup and the Company, and approved by the TSX Venture Exchange, prior to closing of the Merger). Enhanced Operational Scale: The proposed Merger creates a consolidated precious metals company with stronger asset utilization, expanded exploration potential, and a unified platform built to navigate dynamic mining markets. Continued Upside Exposure: Shareholders will retain significant ongoing equity ownership in the combined enterprise, allowing them to benefit directly from future growth, anticipated cost synergies, and broader market visibility. “The filing and mailing of our definitive proxy statement marks a critical milestone toward completing this transformative transaction,” said Allen Palmiere, CEO, President & Director of the Company. “Having successfully executed a turnaround at the Don David Gold Mine, we are positioned to expand production through the proposed Merger. The addition of Goldgroup’s San Francisco mine and Cerro Prieto mine is expected to increase gold exposure and materially enhance cash generation through higher overall output.” The Board of Directors of the Company has thoroughly reviewed the proposed Merger and strongly urges GRC’s shareholders to vote “FOR” the proposals within the definitive proxy statement. What Our Shareholders Are Voting On At the upcoming Special Meeting, our shareholders will be asked to consider and vote upon: The Merger Proposal: To approve the Arrangement Agreement and Plan of Merger. The Merger-Related Compensation Proposal: To approve, on a non-binding advisory basis, the merger-related executive compensation. The Adjournment Proposal: To approve the adjournment of the Special Meeting to a later date, if necessary, to solicit additional proxies for the approval of the Merger Proposal. Your Vote is Required—How to Cast It Now Because approval of the Merger Proposal requires a definitive majority threshold of all outstanding shares to pass, not voting has the exact same effect as voting “AGAINST” the Merger. Every single vote matters, regardless of how many shares you own. Shareholders are highly encouraged to submit their proxy votes ahead of time using one of the following quick methods: Vote Online: Go to the secure website listed on your proxy card or voting instruction form and enter your unique control number.

Gold Resource Corporation Announces First Quarter 2026 ResultsMay 7, 2026 5:52 PM
Business Wire Gold Resource Corporation (NYSE American: GORO) (the “Company”) is pleased to announce the first quarter production results from its Don David Gold Mine. During the quarter, the Company’s production included sales of 374,232 ounces of silver, 1,548 ounces of gold, and a total gold equivalent (“AuEq”) ounces of 8,749. Total cash costs were $2,164 per AuEq ounce, and with continued investment in the mine infrastructure and drilling resulted in an all-in sustaining cost of $3,476 per AuEq ounce. The Company had a net income of $4.7 million, or $0.03 per share, for the quarter. “We are pleased to report another strong quarter and returning the Company to positive net income, with $40.2 million in working capital and $31.0 million in cash and cash equivalents as of March 31, 2026,” said Allen Palmiere, President and CEO. “We continued to make meaningful progress in strengthening operational performance at Don David while advancing the proposed transaction with Goldgroup Mining Inc., which we expect to close in the third quarter. Our ongoing exploration programs continue to expand resources in the area surrounding the mine and the definition drilling has been improving our margins. As we work through the transaction, our team continues to focus on disciplined execution, safety, cost and grade control, and the delivery of returns for our shareholders.” Don David Operational Highlights for the Quarter In the first quarter of 2026, DDGM, located in Mexico, produced and sold a total of 8,749 AuEq ounces, comprised of 1,548 gold ounces and 374,232 silver ounces, at an average realized sales price per ounce of $5,098 and $98.09, respectively. The 74,444 total tonnes milled was 31% higher than in the same period in 2025. Metal production for gold and silver increased by 126% and 54%, respectively. Copper, lead, and zinc production also increased by 39%, 36%, and 64%, respectively. During the first quarter of 2026, underground grade-control, infill, and selective expansion drilling continued to focus on near-term production targets at Arista and at the Alta Gracia project. At Arista, drilling supported production planning and refinement of the geologic model for veins within the Arista system, including the Viridiana, Gisela, Candelaria, Marena North and Splay 31 veins, as well as the Sandy and Sadie veins of the Three Sisters system. Limited surface expansion drilling also commenced during the quarter, testing the Isabel SE target. At the Alta Gracia Project, surface and underground infill and expansion drilling advanced evaluation of the Mirador and Independencia vein systems. Merger Update On January 26, 2026, the Company announced that it entered into a definitive arrangement agreement and plan of merger (the “Arrangement Agreement”) with Goldgroup Mining Inc. (“Goldgroup”), whereby Goldgroup agreed to acquire all of the issued and outstanding shares of the Company’s common stock (the “Transaction”). Pursuant to the Arrangement Agreement, the Company’s stockholders will receive 1.4476 common shares of Goldgroup for each share of the Company’s common stock (as adjusted by a share consolidation to be completed by Goldgroup prior to closing). The Transaction is expected to close in the third quarter of 2026, subject to customary closing conditions (including approval by the stockholders of each of the Company and Goldgroup). The parties received unconditional approval from the Mexican National Antitrust Commission in respect of the Transaction on April 27, 2026.

Gold Resource Corporation Announces Contract With SLR for Completion of the Back Forty Feasibility StudyApril 13, 2026 5:57 PM
Business Wire
Gold Resource Corporation (NYSE American: GORO) (the “Company”) today announced that it has engaged Responsible Mining Solutions Corp. (“RMS”) a part of SLR Consulting Ltd. (“SLR”), to complete a comprehensive feasibility study (the “Feasibility Study”) for the Company’s wholly owned Back Forty project, located in the Upper Peninsula of Michigan.


The Feasibility Study will evaluate technical, economic, and operational parameters associated with the Back Forty project, including mine design considerations, processing options, infrastructure requirements, environmental factors, and project economics. Work under the agreement will commence immediately.


This engagement represents a key milestone in Gold Resource Corporation’s broader growth strategy, as the Company advances its efforts to expand its North American asset base and strengthen its long-term production profile. The Feasibility Study is expected to provide a critical foundation for informed decision making regarding the scope, sequencing, permitting and execution of the project.


SLR was selected based on its extensive experience in mining engineering, mineral economics, and project development, as well as its familiarity with complex feasibility level evaluations. The Company expects the engagement to support not only the initial Feasibility Study but also potential follow-on technical work and permitting support as the project advances.


In October 2023, the Company published a Technical Report Summary (the “TRS”) in compliance with Subpart1300 of Regulation S-K. Using gold prices of $1,800 per ounce, silver prices of $23.30 per ounce and copper prices of $3.90 per pound, the TRS resulted in an IRR of 25.7% and an NPV@6% of $214.5 million. The Company expects that the current commodity environment will result in a significantly higher valuation for the project and support a production decision in the future.

Gold Resource Corporation Reports Financial Results for the Year Ended December 31, 2025March 18, 2026 5:43 PM
Business Wire
Gold Resource Corporation (NYSE American: GORO) (the “Company”) is pleased to announce its full-year operational results from its Don David Gold Mine (“DDGM”) near Oaxaca, Mexico, and a corporate update on its other activities.


“We are pleased to report a successful operational turnaround during 2025 that culminated in a strong fourth quarter finish and over $25 million in cash and equivalents on the balance sheet,” said Allen Palmiere, President and CEO. “Obviously, favorable metal prices were a meaningful contribution which realized an average of $55 per ounce for silver and $4,234 per ounce for gold metal sales. Production from our Three Sisters zone made a significant contribution, as expected, and as a result we anticipate that silver will represent approximately 40% of our output from this zone in 2026 and enhance our leverage to the silver market. Our operations team in Mexico has executed exceptionally well on our 2025 objectives, delivering solid year end results, positioning us for continued momentum in the year ahead.”


Don David Gold Mine:



Production substantially improved, as the Company began receiving newly acquired equipment at the end of the third quarter. The additional equipment, combined with the strategic use of third-party contractors, enabled an increase in available headings to mine and a subsequent improvement in production.



DDGM produced and sold a total of 23,125 gold equivalent ounces, comprising of 4,944 gold ounces and 1,461,898 silver ounces, sold at an average price per ounce of $3,657 and $45.48, respectively. DDGM total cash costs after co-product credits per gold equivalent (“AuEq”)1 ounce sold and DDGM all-in sustaining cost per AuEq ounce sold for the year were $2,205 and $2,807, respectively. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Measures for a reconciliation of non-GAAP measures to applicable GAAP measures.



DDGM received the Mexican Empresa Socialmente Responsable (“ESR”) award in 2025 for the eleventh consecutive year.



During 2025, the Company’s exploration program focused on underground grade-control and infill drilling in support of near-term production, primarily at the Three Sisters and Arista vein systems. At Three Sisters, drilling targeted the Sandy and Sadie vein sets to refine and validate the geologic model for production planning. Additional definition drilling was completed on multiple veins within the Arista system, including Splay 31, Candelaria, Marena, Santa Helena, Viridiana, and Marena North, as well as the Soledad South vein in the Switchback vein system. Exploration-related underground development advanced throughout the year, positioning the Company to continue expansion drilling in early 2026. In addition, limited surface infill drilling also commenced at the Alta Gracia project in the fourth quarter, focusing on the Mirador vein system.



Corporate and Financial:



The Company closed the year with a $25.0 million cash and cash equivalents balance at December 31, 2025. The increase of $23.4 million from December 31, 2024 is the result of the Company’s focus on improving its cash position, mostly through the issuance of debt and equity in 2025, as well as improved production and higher metal prices.


The Company raised $2.5 million through a registered direct offering in January 2025. In September 2025, the Company closed on a second registered direct offering of $11.4 million for the sale of 25,315,954 shares of the Company’s common stock at a price of $0.45 per share. The Company issued 14,204,846 of these shares, for the fair value of approximately $6.4 million, to fully pay off the term loan received in June 2025, as a non-cash equity settlement.



The Company raised $8.6 million through its At-The-Market Offering Program (the “ATM Program”), after deducting the agent’s commissions and other expenses.



In February 2025, the Company sold its interest in Green Light Metals for $0.9 million in proceeds.



On May 7, 2025, the Company received a tax refund of 79.6 million pesos (approximately $4.0 million) related to DDGM taxes paid in 2023.






Working capital at December 31, 2025, was $32.0 million, a 1,424% increase from the December 31, 2024 working capital of $2.1 million. The increase is primarily driven by the increase in cash and cash equivalents.

I have not logged into my Schwab account in years ever since TDA is gone. I had ZERO balance in there but have stocks that are petrified LOL. 3 or 4 company's that can't be sold. LOL I don't even know what has been happening with that account.

In 1.07, fantastic ratings https://swingtradebot.com/equities/GORO#google_vignette

$GORO $0.95 isn’t hype—it’s a stabilized story finally playing out. That $2.5M Jan ’25 dilution? Ronin was right—it was the protein pill we needed: bridged operations, reduced future dilution, and funded the Don David ramp to $1,512/t NSR grades. Add in Back Forty resuming development (NPV now $430M+ with $4,400 Au) and shorts shrinking from 20% ? 1%, and the charts confirm it: weeklys +27%, golden cross in place, testing $1.18 52-week high. Entry $0.90–$0.92, stop $0.85, upside $1.38–$1.50. Know what you own—this isn’t a pump; it’s a producing mine firing on all cylinders. 🚀

Maybe a forward split of 10 for 1 will make it go down then. xD

Ugh, another dilution comment… YES, they must be diluting, thats why the stock keeps going up rather than down. After all, we all know thsts how dilution works…

Nice trend up here. Let's hope they've gotten their act together...

That is for sure

GORO is a fine example of a company managed using DEI rules. Everybody got a piece of the action except the shareholders. We got stuck holding the bag. This company is toast. It is a good thing they split from FTCO. And FTCO took all the management experience with them. Glad I dumped them 18 months ago. Held 250 shares to remind myself the warning signs of DEI.

Management to out an extremely large amount over the last five years for the poor production of the mine

Not good ... looks like a prime example of a company that didn't replace it's mineable reserves in time ... and now appears to have run out of the cash needed to acquire a new mineable replacement/transition asset.

The co should have been sold a year ago

The co should have been sold a year ago

I think it broke the wrong way
I was sure hoping you were right
Management fill there pockets and we get shit on as stock holders

Me to

GORO...GOLDIE READY TO BREAK

Any thoughts on this? I'm in for 16k and would appreciate any input.

With management taking out as much as they do and we are taking in more from the increase in gold.
I wounded if better management or new management might do a better job

can't pay a div if no income

Investors still missed about losing their dividends.

This stock is stagnant despite gold in new highs

Daytraders tried to flush this again with AM large dumps. Price came back strong. Time to go long , imho

MMs have been holding this down with large dumps after gaining a few Pennies. They tried to get this back down to .25 to collect stock. With gold over $2500/oz now, we might spring up to .70s again

Management needs replacement
Anyone could do as good a job as them. I am volunteering

as of now it is 49.6 million
shorts seem to have been covering which may be reasson SP rose.
eafrnings due latetr this month
It had earnings and paid a Div up untill 2022 so it could be aboout to post positive earnings

JSC,

THINK BUY OUT!!! Are the GORO holdings worth $50-60 million?
