Master legal disclaimer

Please read first

This website and any affiliated digital materials are published by Machurucuto Corp (4501 Langdon Dr, Suite 101, Morrisville, NC 27560, United States), which operates GORO Stocks (gorostocks.gold) and has been compensated to produce and distribute promotional content regarding Goldgroup Mining Inc. (the “subject company”). This communication is a paid advertisement — not a research report, not investment advice, and not an independent publication. Machurucuto Corp is not a broker-dealer, investment adviser, or securities analyst. Investing in small-cap or micro-cap securities is highly speculative and may result in the total loss of your investment. Consult a licensed investment professional and perform your own due diligence.

1 · Nature and intent of this communication

Machurucuto Corp is a for-profit marketing agency engaged in paid promotion of public companies. The content it produces is strictly commercial and is intended to create temporary public awareness, visibility and short-term market activity around the featured company. This material is not impartial. Read it as a paid commercial advertisement — not as editorial, research or independent commentary. These are advertisements, not analysis, and are not intended as factual evaluations of the company's operations or investment merit.

2 · Compensation

Machurucuto Corp has been engaged, for compensation, to provide awareness and promotional media services regarding the subject company. This arrangement creates a direct, material and unavoidable conflict of interest: treat all content here as promotional, financially motivated, and produced for the benefit of the party that pays for it. Assume that any statement about the subject company is materially influenced by that compensation. Neither Machurucuto Corp nor the paying party makes any representation, warranty or guarantee as to the accuracy, timeliness or completeness of the information provided, and both disclaim any liability for investment losses that may result from reliance on this material.

3 · Intended audience

This communication is directed solely to U.S.-based, self-directed investors who understand the risks of investing in micro-cap and exchange-listed securities. It is not intended for children, seniors, retirement accounts, or individuals with limited securities-trading experience, and it is not intended to guide long-term portfolio management or financial planning.

4 · No endorsement or verification of company claims

Machurucuto Corp has not independently verified, investigated, audited or substantiated any statement, representation or claim made by the featured company, its officers, directors, employees, affiliates, agents, press releases, marketing materials or any third-party source. Assume that all information regarding the subject company — including business descriptions, operational updates, technical or resource data, partnerships, projections, market estimates and strategic plans — is unverified, unaudited, incomplete, potentially inaccurate, and subject to change without notice. Do not treat publication of these statements as an endorsement or confirmation of their validity, and do not rely on any company-provided claim, projection or forward-looking statement in making an investment decision. If you invest, you do so entirely at your own risk; conduct your own independent due diligence, including a review of the issuer's regulatory filings, before making any decision.

5 · Market influence and expected trading pattern

Paid promotional campaigns for small- and micro-cap securities often cause temporary, artificial and unsustainable increases in share price and trading volume, driven by short-term speculative interest rather than any change in the underlying business. You should assume and expect that the subject company's share price may rise sharply during active promotion; that volume may spike on speculative buying; that once buying interest subsides or the promotion ends — which can happen suddenly and without notice — the price may decline precipitously, potentially to pre-promotion levels or lower, within days or hours; and that such movements need not correlate with the company's fundamentals. Such spikes are frequently followed by steep, rapid and often irreversible losses. If you buy during or shortly after a promotional period, be prepared for a high probability of losing a substantial portion, or all, of your investment. By engaging with this content you accept that you understand this and will not hold Machurucuto Corp responsible for losses resulting from such trading patterns.

6 · No reliance; investor responsibility

The burden of research, verification and risk assessment rests entirely with you. All content here is promotional and should not be the basis for any investment decision. You are solely responsible for reviewing all publicly available information (including the issuer's regulatory filings and audited financial statements), for consulting a licensed investment professional, attorney or tax adviser, and for understanding the risks inherent in micro-cap and early-stage public companies, which may include extreme volatility, illiquidity, limited financial transparency, insider selling, share dilution, regulatory challenges and business failure. By viewing this material you agree that you will not rely solely on it, that you accept full responsibility for independent due diligence, and that Machurucuto Corp and its affiliates will not be liable for losses arising from your reliance on this content.

7 · Forward-looking statements

This material may contain forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and applicable Canadian securities laws — words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “may,” “will,” “should,” “could,” “projects,” “estimates,” “potential” and similar expressions. These statements are inherently uncertain, rest on assumptions that may prove incorrect, and involve known and unknown risks that may cause actual results to differ materially. Do not place undue reliance on them. Machurucuto Corp undertakes no obligation to update any forward-looking statement except as required by law.

8 · Information sourcing, bias and accuracy

This content uses publicly available information, including company websites, press releases and materials supplied by the paying party or related parties, which Machurucuto Corp does not verify or validate. Assume all information presented is subjective, not independently verified, created to highlight potential upside and to omit downsides, and not suitable as the basis for any investment decision.

9 · Ownership and trading conflicts

Machurucuto Corp, its contractors, members and affiliates, and the paying party and its affiliates, may hold, acquire or dispose of securities of the subject company, and may buy or sell them without prior notice, before, during or after a promotional campaign. Such transactions may affect market pricing. Machurucuto Corp is not obligated to update readers on its trading activity or holdings.

10 · Marketing, data collection and consent

Promotional tools used may include email and newsletters, SMS/MMS, social media and influencers, display advertising, press releases and video. By engaging with this content you consent to receive ongoing marketing communications; you may unsubscribe at any time, though data may be retained for audit or compliance purposes.

11 · Advertising-law compliance

Machurucuto Corp produces promotional content in line with the advertising-disclosure standards of the Federal Trade Commission and the SEC's guidance on sponsored, investment-related communications, and makes good-faith efforts to disclose compensation arrangements, conflicts of interest, risks, the limits of its role and the promotional nature of this content. Machurucuto Corp does not provide investment recommendations under any regulatory framework, including SEC Regulation Analyst Certification, FINRA Rule 2210 or Regulation Best Interest.

12 · Non-U.S. users

This material is intended solely for distribution within the United States. If you access it from outside the U.S. you are responsible for complying with your local laws, and Machurucuto Corp disclaims liability for access from jurisdictions where promotion or solicitation of securities is restricted.

13 · Disclaimer of warranties; limitation of liability

Editorial control. This has not been described. Assume nothing about who reviewed or approved this text before it was published.

18 · Important information — technical & forward-looking

Scientific and technical information regarding the subject company is that of the company and its Qualified Persons under National Instrument 43-101 (“NI 43-101”), as set out in the company's technical reports (including reports on its Don David, Cerro Prieto, San Francisco and Back Forty projects) filed on SEDAR+. Readers are encouraged to read each technical report in its entirety, including all qualifications, assumptions, exclusions and risk factors; each report is intended to be read as a whole and sections should not be relied on out of context.

The company states that the technical aspects of its September 2026 corporate presentation were reviewed and approved by Craig Gibson of Goldgroup Mining Inc., a Qualified Person under NI 43-101. The estimates it publishes rest on: the San Francisco NI 43-101 technical report dated May 1, 2026 with an effective date of April 30, 2026, prepared by Micon International Limited; the Cerro Prieto technical report with an effective date of April 4, 2025, prepared by Rodrigo R. Carneiro, José A. Olmedo and Cristian Garcia; the Don David S-K 1300 technical report as at December 31, 2025.

On the production figures quoted anywhere on this page. The company labels a portion of them in-house estimates (San Francisco, and the heap-leach and expansion programmes at Cerro Prieto) and others based on historic data. San Francisco does not have demonstrated mineral reserves and its production rates are conceptual only; the company states expressly that its potential production is too early to be considered official guidance, and that the group targets assume a positive decision on and execution of the restart. Stated mine lives are conceptual, rest on existing mineral resource estimates that may not have demonstrated economic viability, and assume an inferred-conversion rate; there is no guarantee that resources can be converted into economical reserves.

Mineral resources that are not mineral reserves do not have demonstrated economic viability, and a preliminary economic assessment is preliminary in nature and may include inferred mineral resources that are too speculative geologically to be categorised as mineral reserves; there is no certainty that the results, assumptions or conclusions of any such assessment will be realised. Resource and reserve estimates may be materially affected by geological, metallurgical, environmental, permitting, legal, title, taxation, socio-political, marketing and other factors.

Forward-looking information regarding the subject company — including any statement about future production, project restart, timing, economics, financing, permitting, exploration results, reserve or resource estimates, integration of acquisitions, future cash flow, market recognition or shareholder value — is subject to known and unknown risks and uncertainties, including commodity-price and exchange-rate fluctuations, cost inflation, exploration and mining risk, the risk that a project restart may not occur or may not occur on anticipated terms, the risk that assumptions or conclusions of a preliminary economic assessment may not be realised, permitting and regulatory risk, financing risk, and jurisdiction-specific political and economic risk, among others. There can be no assurance any such outcome will occur. Review the subject company's public filings and technical reports in their entirety, including their risk factors, before making any investment decision.
