RECENT DEVELOPMENTS

Amended Arrangement Agreement

On December 10, 2025, Robex Resources Inc. (“ Robex” or the “Corporation ”) entered into an amending agreement (the “ Amending Agreement ”) with Predictive Discovery Limited (“ Predictive ”) and 9548-5991 Québec Inc. (“ Acquireco ”) to amend the previously announced arrangement agreement dated October 5, 2025 among Robex, Predictive and Acquireco (the “ Original Arrangement Agreement ” and, as amended by the Amending Agreement, the “ Arrangement Agreement ”), pursuant to which Acquireco, a direct wholly-owned subsidiary of Predictive, will acquire all of the issued and outstanding common shares of Robex (“ Robex Shares ”) by way of a statutory plan of arrangement (the “ Arrangement ”) under Chapter XVI – Division II of the Business Corporations Act (Québec) (the “ Transaction ”).

Under the terms of the Amending Agreement, holders of Robex Shares (“ Robex Shareholders ”) will now receive 7.862 fully paid ordinary shares in the capital of Predictive (“ Predictive Shares ”) for each Robex Share held (the “ Amended Consideration ”). Following completion of the Transaction, existing Predictive shareholders and former Robex Shareholders will own approximately 53.5% and 46.5%, respectively, of the Combined Company on a fully diluted in-the-money basis.

The terms of the Amending Agreement were agreed by Robex, Acquireco and Predictive following receipt by Predictive of an acquisition proposal from a third party (“ Competing Offer ”) as announced by Predictive on December 3, 2025 for all of the issued and outstanding Predictive Shares. In accordance with the terms of the Arrangement Agreement, the board of directors of Predictive subsequently determined that the Amending Agreement resulted in the Competing Offer ceasing to be a superior proposal under the Arrangement Agreement. A copy of the Amending Agreement has been filed on the Corporation’s SEDAR+ profile at www.sedarplus.ca.

Board Recommendation

Based on the unanimous recommendation of the Robex Special Committee, and after consultation with its outside financial and legal advisors, the Robex Board has unanimously determined that the Arrangement is in the best interests of Robex, and that the Amended Consideration to be received by Robex Shareholders pursuant to the Transaction is fair, from a financial point of view, to the Robex Shareholders. The Robex Board unanimously recommends that Robex Shareholders vote FOR the Arrangement Resolution at the Meeting.

Rationale for the Transaction

In reaching its conclusion that the Arrangement is in the best interests of the Corporation and that the Amended Consideration to be received by the Robex Shareholders is fair, from a financial point of view, to the Robex

Shareholders, the Robex Board and the Special Committee considered and relied upon a number of factors and reasons, including, but not limited to, the following:

Shareholder Support. Strong support from Robex Shareholders for the Transaction, including the Robex Supporting Shareholders, owning in the aggregate approximately 23.8% of the issued and outstanding Robex Shares, who have entered into the Amended Voting Support Agreements and agreed to vote their Robex Shares FOR the Arrangement Resolution at the Meeting.
Strategic Combination. The merger creates one of West Africa’s leading gold producers, combining two of the region’s largest, lowest-cost, and most advanced gold projects—Kiniero and Bankan—with projected production of +400koz Au[1] of production by 2029, combined Mineral Resources of approximately 9.5Moz Au[2] comprised of 6.6Moz measured and indicated Mineral Resources and inclusive of Ore Reserves of approximately 4.5Moz Au, and 2.9Moz inferred Mineral Resources.
Financial Flexibility. Cash flows from Kiniero and warrant proceeds from Robex provide funding capacity for Bankan’s development, reducing financing risk.
Operational Synergies. Proximity of projects enables a tier-1 mining hub, optimising development, exploration, and workforce deployment.
Enhanced Market Profile. Greater scale and multi-asset nature position the Combined Company for potential inclusion in major indices (ASX 200, GDXJ), improving liquidity and investor appeal.
Experienced Leadership. A strengthened management team with proven in-country expertise and duallisted company experience ensures effective execution.
Share Price Re-Rate. Potential for a higher relative share price re-rate of the merged group driven by increased scale, imminent gold production growth, multi-asset profile, and enhanced index inclusion opportunities.
Fairness Opinions. The Special Committee and the Robex Board received the Second Fairness Opinions (as defined below) to the effect that, as of the date thereof, and subject to the assumptions, limitations and qualifications set out therein, the Amended Consideration to be received by the Robex Shareholders pursuant to the Arrangement is fair, from a financial point of view to the Robex Shareholders.

Robex Shareholders should also refer to the considerations set forth under “ Part 6 – The Arrangement – Reasons for the Arrangement ” of the Circular.

Second Fairness Opinions

Each of Cormark Securities Inc. (“ Cormark ”) and Canaccord Genuity Corp.

Fairness Opinion ”) and an updated Canaccord Fairness Opinion (the “ Second Canaccord Fairness Opinion ” and together, the “ Second Fairness Opinions ”), respectively. On December 10, 2025, Cormark provided the Second Cormark Fairness Opinion orally to the Special Committee, which was subsequently confirmed in writing, to the effect that, as of the date of such Second Cormark Fairness Opinion, and subject to the assumptions, limitations and qualifications set out therein, the Amended Consideration to be received by the Robex Shareholders pursuant to the Arrangement, is fair, from a financial point of view, to the Robex Shareholders. Additionally, on December 10, 2025, Canaccord provided the Second Canaccord Fairness Opinion orally to the Robex Board, which was subsequently confirmed in writing, to the effect that, as of the date of such Second Canaccord Fairness Opinion, and subject to the assumptions, limitations and qualifications set out therein, the Amended Consideration to be received by the Robex Shareholders pursuant to the Arrangement, is fair, from a financial point of view, to the Robex Shareholders.

The full text of the Second Fairness Opinions are attached as Exhibit A to this Addendum. Robex Shareholders are urged to, and should, read the Second Fairness Opinions in their entirety. This summary is qualified in its entirety by reference to the full text of the Second Fairness Opinions.

Subject to the terms of their engagements, each of Cormark and Canaccord have consented to the inclusion in this Addendum of their respective Second Fairness Opinions in their entirety, and the references to their respective Second Fairness Opinions herein. The Second Canaccord Fairness Opinion and the Second Cormark Fairness Opinion were provided to the Robex Board and the Special Committee, respectively, for their exclusive use only in considering the Arrangement and may not be relied upon by any other person or for any other purpose or published or disclosed to any other person, relied upon by any other person or used for any other purpose without the express written consent of Cormark in the case of the Second Cormark Fairness Opinion, and without the express written consent of Canaccord in the case of the Second Canaccord Fairness Opinion.

The Amended Arrangement is subject to, among other things, the requisite approval of Robex Shareholders for the Amended Arrangement, which consists of the affirmative vote of at least (i) 66[2/3] % of the votes cast in person or by proxy by Robex Shareholders at a special meeting of Robex Shareholders to be held to consider the Amended Arrangement (the “ Robex Meeting ”), and (ii) if applicable, a simple majority of the votes cast in person or by proxy by Robex Shareholders at the Robex Meeting, excluding the votes of any shareholder whose votes are required to be excluded pursuant to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions (“ MI 61-101 ”).

The terms and conditions of, and other matters relating to, the Amended Arrangement are provided for in the Amended Arrangement Agreement and will be described in the addendum (the “ Addendum ”) to the management information circular of Robex dated November 11, 2025 (the “ Management Information Circular ”), which will be mailed to the Robex Shareholders in connection with the Robex Meeting. Canaccord Genuity further understands that, in connection with the Amended Arrangement, all of the directors and certain of the senior officers of Robex, along with The Cohen Group and Eglinton Mining, each intend to enter into an amended and restated voting support agreement with Predictive (each, an “ Amended Robex Support Agreement ”) pursuant to which, and subject to the terms and conditions thereof, they will agree to, among other matters, vote their Robex Shares (and the Robex Shares controlled or directed by them) in favour of approving the Amended Arrangement.

All dollar amounts herein are expressed in Canadian dollars, unless otherwise indicated.

Engagement of Canaccord Genuity

Canaccord Genuity was first contacted about a potential engagement on July 7, 2025 and formally engaged by the Company through an agreement between the Company and Canaccord Genuity (Australia) Ltd. dated July 31, 2025 (the “ Engagement Agreement ”). The Engagement Agreement provides the terms upon which Canaccord Genuity has agreed to provide the Original Opinion and Updated Opinion to the Board in connection with the Original Arrangement and Amended Arrangement. The terms of the Engagement Agreement provide that Canaccord Genuity is to be paid certain fees for its services as financial advisor, including (i) a fixed fee due upon delivery of the Updated Opinion (the “ Opinion Fee ”), and (ii) a fee payable upon completion of the Original Arrangement, Amended Arrangement or any alternative transaction. The Opinion Fee payable to Canaccord Genuity pursuant to the Engagement Agreement does not depend, in whole or in part, upon the Updated Opinion being favourable or the conclusions reached in the Updated Opinion, nor does it depend, in whole or in part, upon the outcome or successful completion of the Original Arrangement or Amended Arrangement. In addition, Canaccord Genuity is to be reimbursed for its reasonable out-of-pocket expenses and to be indemnified by the Company in respect of certain liabilities that might arise in connection with its engagement.

Canaccord Genuity consents to the inclusion of the Updated Opinion in its entirety and a summary thereof in the Addendum, and to the filing thereof, as necessary, by the Company with the securities commissions or similar regulatory authorities in each province and territory of Canada and with the TSX Venture Exchange, provided that the contents of the Addendum (i) comply with all applicable securities laws (including applicable published policy statements of Canadian securities regulatory authorities), and (ii) are approved in writing by Canaccord Genuity, which approval shall not be unreasonably withheld.

Credentials of Canaccord Genuity

Canaccord Genuity is an independent investment bank which provides a full range of corporate finance, merger and acquisition, financial restructuring, sales and trading, and equity research services. Canaccord Genuity operates in North America, the United Kingdom, Europe, Asia and Australia.

The Updated Opinion expressed herein represents the views and opinions of Canaccord Genuity, and the form and content of the Updated Opinion have been approved for release by a committee of Canaccord Genuity's managing directors, each of whom is experienced in merger, acquisition, divestiture, fairness opinion, and capital markets matters.

Independence of Canaccord Genuity

Neither Canaccord Genuity nor any of its affiliates (as such term is defined in the Securities Act (Québec)) is an insider, associate, or affiliate of the Company or Predictive. Other than with respect to Predictive’s May 2024 Financing (as defined herein) as well as Robex’s May 2025 Financing (as defined herein), Canaccord Genuity and its affiliates have not been engaged to provide any financial advisory services to, and have not acted as lead or co-lead manager on any offering of securities of, the Company, Predictive, or any of their respective affiliates during the two years preceding the date on which Canaccord Genuity was engaged by the Board in respect of the Original Arrangement or the Amended Arrangement, other than services provided under the Engagement Agreement or described herein. Canaccord Genuity acted as joint lead manager and joint bookrunner for Predictive’s A$50,000,000 placement of ordinary shares, which closed May 2, 2024 (the “ May 2024 Financing ”), and as joint lead manager for Robex’s A$120,000,000 initial public offering of CHESS depository interests on the Australian Securities Exchange, which closed May 30, 2025 (the “ May 2025 Financing ”).

The Opinion Fee payable to Canaccord Genuity pursuant to the Engagement Agreement is not financially material to Canaccord Genuity and does not give Canaccord Genuity any financial incentive in respect of either the conclusions reached in the Updated Opinion or the outcome of the Amended Arrangement. There are no understandings, agreements or commitments between Canaccord Genuity and either the Company, Predictive, or any of their respective associates or affiliates with respect to any future business dealings. However, Canaccord Genuity may, in the future, in the ordinary course of its business, perform financial advisory or investment banking services for the Company, Predictive, or any of their respective associates or affiliates.

In addition, Canaccord Genuity and its affiliates act as a trader and dealer, both as principal and agent, in major financial markets and, as such, may have had and may in the future have long or short positions in the securities of the Company, Predictive, or any of their respective associates or affiliates and, from time to time, may have executed or may execute transactions on behalf of such companies or clients for which it receives or may receive commission(s). As an investment dealer, Canaccord Genuity and its affiliates conduct research on securities and may, in the ordinary course of their business, provide research reports and investment advice to their clients on investment matters, including with respect to the Company, Predictive, and/or the Amended Arrangement. In addition, Canaccord Genuity and its affiliates may, in the ordinary course of their business, provide other financial services to the Company, Predictive, or any of their associates or affiliates, including advisory, investment banking and capital market activities such as raising debt or equity capital. The rendering of this Updated Opinion will not in any way affect Canaccord Genuity’s ability to continue to conduct such activities.

Canaccord Genuity has not, to the best of its knowledge, been denied access by either the Company or Predictive to any information under its or their control, respectively, requested by Canaccord Genuity.

Canaccord Genuity did not meet with the auditors or technical consultants of either the Company or Predictive and has assumed the accuracy and fair presentation of, and has relied upon, the audited consolidated financial statements of Robex and Predictive and the reports of the auditors thereon, as well as the relevant technical reports of Robex and Predictive, as presented.

Prior Valuations

The Company has represented to Canaccord Genuity that, to the best of their knowledge, information and belief, there have been no independent appraisals, valuations or material non-independent appraisals, valuations or material expert reports, including without limitation any “prior valuations” (as defined in MI 61-101) relating to the Company, any of its subsidiaries (as defined in the Securities Act (Québec)) or any of its or their material assets, securities or liabilities which have been prepared as of a date within two years preceding the date hereof.

Assumptions and Limitations

The Updated Opinion is subject to the assumptions, qualifications, explanations and limitations set forth herein.

Canaccord Genuity has not prepared a formal valuation or appraisal of the Company or Predictive or any of their respective securities or assets and the Updated Opinion should not be construed as such. Canaccord Genuity has, however, conducted such analyses as it considered necessary and appropriate at the time and in the circumstances. In addition, the Updated Opinion is not, and should not be construed as, advice as to the price at which any securities of the Company or Predictive may trade at any future date. We are not legal, tax or accounting experts, have not been engaged to review any legal, tax or accounting aspects of the Amended Arrangement and express no opinion concerning any legal, tax or accounting matters concerning the Amended Arrangement. Without limiting the generality of the foregoing, Canaccord Genuity has not reviewed and is not opining upon the tax treatment under the Amended Arrangement.

With the Company’s approval and as provided for in the Engagement Agreement, Canaccord Genuity has relied upon the completeness, accuracy and fair presentation of all of the information and documentation (financial or otherwise), data, opinions, appraisals, valuations and other information and materials of whatsoever nature or kind relating to the Company, Predictive and their respective subsidiaries and other affiliates and the Amended Arrangement, and publicly available information and representations (oral or written), and data prepared or supplied by the Company, Predictive or any of their respective subsidiaries and respective agents and advisors (collectively, the “ Information ”), and we have assumed that this Information did not omit to state any material fact or any fact necessary to be stated to make such Information not misleading. The Updated Opinion is conditional upon the completeness, accuracy and fair presentation of such Information. Subject to the exercise of our professional judgment and except as expressly described herein, we have not attempted to verify independently the completeness, accuracy or fair presentation of any of the Information. With respect to the financial projections provided to Canaccord Genuity by the Company and used in the analysis supporting the Updated Opinion, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgements of management of the Company, as to the matters covered thereby and which, in the opinion of the Company, are (and were at the time of preparation and continue to be) reasonable in the circumstances. By rendering the Updated Opinion, we express no view as to the reasonableness of such forecasts, projections, estimates or the assumptions on which they are based.

In preparing the Updated Opinion, Canaccord Genuity has made several assumptions, including, among other things, that all of the conditions required to implement and complete the Amended Arrangement as described in the Amended Arrangement Agreement will be satisfied substantially in accordance with its terms and without any adverse waiver or amendment of any material term or condition thereof, that all necessary consents, permissions, approvals,

==> picture [54 x 29] intentionally omitted <==

exemptions and/or orders required from third parties or governmental authorities will be obtained without adverse condition or qualification, that the final executed versions of all draft documents referred to under “Scope of Review” above will not vary in any material respect from the most recent draft versions thereof reviewed by us, that the Amended Arrangement will proceed as scheduled and without material additional costs to the Company or liabilities of the Company to third parties, that the procedures being followed to implement the Amended Arrangement are valid and effective, that all of the representations and warranties contained in the Amended Arrangement Agreement are correct as of the date hereof, and that the disclosure to be provided in the Addendum with respect to the Company, Predictive, and their respective affiliates and the Amended Arrangement will be accurate in all material respects and state all material facts related to the Amended Arrangement Agreement and comply with applicable securities laws.

Senior officers of the Company have represented to Canaccord Genuity in the Representation Letter, among other things, that (i) other than FOFI (as defined below), the information, data, documents, advice, opinions, representations and other material (financial and otherwise), whether in written, electronic, graphic, oral or any other form or medium with respect to the Company and its subsidiaries provided to Canaccord Genuity by the Company or its subsidiaries or its or their representatives, agents or advisors, for the purpose of preparing the Updated Opinion (the “ Company Information ”) taken as a whole, was, at the date the Company Information was provided to Canaccord Genuity, and is at the date hereof, complete, true and correct in all material respects and did not and does not contain any untrue statement of a material fact in respect of the Company or its subsidiaries or the Amended Arrangement and did not and does not omit to state a material fact in relation to the Company or its subsidiaries or the Amended Arrangement, in each case necessary to make the Company Information or any statement contained therein not misleading in light of the circumstances under which the Company Information was provided or any statement was made; (ii) since the dates on which the Company Information was provided to Canaccord Genuity, other than in respect of the Amended Arrangement, there has been no material change or change in material fact, financial or otherwise, in or relating to the financial condition, assets, liabilities (whether accrued, absolute, contingent or otherwise), business, operations or prospects of the Company or any of its subsidiaries and, to the best of the knowledge, information and belief of the certifying officers, of Predictive and its subsidiaries, and no material change or change in material fact has occurred in the Company Information or any part thereof which would have or which would reasonably be expected to have an effect on the Updated Opinion; (iii) to the best of the knowledge, information and belief of the certifying officers, there are no independent appraisals, valuations or material non-independent appraisals, valuations or material expert reports, including without limitation any “prior valuations” (as defined in MI 61-101) relating to the Company, any of its subsidiaries or any of its or their assets, securities or liabilities which have been prepared as of a date within two years preceding the date hereof nor are the certifying officers aware of any of the foregoing with respect to Predictive, any of its subsidiaries or any of its or their material assets, securities or liabilities;

(vi) the Company has not filed any confidential material change reports or other confidential filings pursuant to the Securities Act (Québec), or analogous legislation in any jurisdiction in which it is a reporting issuer or the equivalent, that remain confidential; (vii) other than as disclosed in the Company Information or the Amended Arrangement Agreement, neither the Company nor any of its subsidiaries has any material contingent liabilities, nor are the certifying officers aware of any of the foregoing with respect to Predictive or any of its subsidiaries, and, to the best of the knowledge, information and belief of the certifying officers, there are no actions, suits, claims, arbitrations, proceedings, investigations or inquiries pending or threatened against or affecting the Amended Arrangement, the Company or any of its subsidiaries at law or in equity or before or by any international, multinational, national, federal, provincial, state, municipal or other governmental department, commission, bureau, board, agency, instrumentality or stock exchange which would reasonably be expected to materially affect the Company or its subsidiaries or the Amended Arrangement, nor are the certifying officers aware of any of the foregoing with respect to Predictive or any of its subsidiaries;

financial forecasts, models, estimates and other future-oriented financial information concerning the Company and its subsidiaries (collectively, “ FOFI ”), provided to Canaccord Genuity was prepared on a basis consistent in all material respects with the accounting policies applied in the most recent audited consolidated financial statements of the Company, and does not contain any untrue statement of a material fact or omit to state any material fact necessary to make such financial material, documentation or other data not misleading in light of the circumstances in which such financial material, documentation and other data were provided to Canaccord Genuity, and to the best of the knowledge, information and belief of the certifying officers, all financial material, documentation and other data concerning Predictive and its subsidiaries, excluding FOFI, provided to Canaccord Genuity was prepared on a basis consistent in all material respects with the accounting policies applied in the most recent audited consolidated financial statements of Predictive, and does not contain any untrue statement of a material fact or omit to state any material fact necessary to make such financial material, documentation or other data not misleading in light of the circumstances in which such financial material, documentation and other data were provided to Canaccord Genuity; (ix) all FOFI provided to Canaccord Genuity (a) was prepared on bases reflecting reasonable estimates, assumptions, and judgements of the Company; (b) was prepared using assumptions which, in the reasonable belief of the Company’s management, were at the time of preparation and continue to be, reasonable in the circumstances, having regard to the Company’s industry, business, financial condition, plans and prospects; (x) the Company has not received any oral or written offers, whether formal or informal, binding or non-binding, for all or a material part of the properties or assets owned by, or the securities of, the Company or any of its subsidiaries within the two years preceding the date hereof; (xi) there are no agreements, undertakings, commitments or understandings (written or oral, formal or informal) to which the Company or any of its subsidiaries is a party which relate to the Amended Arrangement, except as have been disclosed to Canaccord Genuity; (xii) the contents of any and all documents prepared or to be prepared in connection with the Amended Arrangement by the Company for filing with regulatory authorities or delivery or communication to the securityholders of the Company (collectively, the “ Disclosure Documents ”) were, at their respective dates of filing, and will be true and correct in all material respects and did not, as of their respective dates, and will not contain any misrepresentation and the Disclosure Documents complied, as of their respective dates, and will comply in all material respects with all requirements under applicable securities laws; (xiii) the Company has complied in all material respects with the terms and conditions of the Engagement Agreement; and (xiv) the representations and warranties made by the Company in the Amended Arrangement Agreement are true and correct in all material respects and, to the best of the knowledge of the certifying officers, the representations and warranties made by Predictive in the Amended Arrangement Agreement are true and correct in all material respects.

This Updated Opinion is rendered on the basis of securities markets, economic, financial and general business conditions prevailing as of the date hereof and the conditions and prospects, financial and otherwise, of the Company, Predictive, and their respective subsidiaries and affiliates, as they were reflected in both the Information and Company Information and as they have been represented to Canaccord Genuity in discussions with management of the Company and Predictive. In its analyses and in preparing this Updated Opinion, Canaccord Genuity made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, which Canaccord Genuity believes to be reasonable and appropriate in the exercise of its professional judgement, many of which are beyond the control of Canaccord Genuity or any party involved in the Amended Arrangement.

This Updated Opinion has been provided for the sole use and benefit of, and is to be relied upon solely by, the Board in connection with, and for the purpose of, its consideration of the Amended Arrangement, and may not be used or relied upon by any other person or for any other purpose and, except as contemplated herein, may not be quoted from, publicly disseminated or otherwise communicated to any other person without the express prior written consent of Canaccord Genuity, except for the inclusion of the Updated Opinion in its entirety and a summary thereof (in a form acceptable to us) in the Addendum. This Updated Opinion is given as of the date hereof and Canaccord Genuity disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting this Updated Opinion which may come, or be brought, to Canaccord Genuity’s attention after the date hereof. Without limiting the foregoing, in the event that there is any material change in any fact or matter affecting this Updated Opinion after the date hereof, including, without limitation, the terms and conditions of the Amended Arrangement, or if Canaccord Genuity learns that the Information or Company Information relied upon in rendering this Updated Opinion was inaccurate, incomplete or misleading, Canaccord Genuity reserves the right to change, modify or withdraw this Updated Opinion after the date hereof, but, in doing so, does not assume any obligation to update, revise or reaffirm this Updated Opinion and Canaccord Genuity expressly disclaims any such obligation.

==> picture [54 x 29] intentionally omitted <==

This Updated Opinion has been prepared in accordance with the Disclosure Standards for Formal Valuations and Fairness Opinions of the Canadian Investment Regulatory Organization (“ CIRO ”), but CIRO has not been involved in the preparation or review of this Updated Opinion.

This Updated Opinion does not constitute, and is not to be construed as, a recommendation as to how the Board, or any Robex Shareholder (or any other securityholder of the Company) should vote or otherwise act with respect to any matters relating to the Amended Arrangement, or whether to proceed with the Amended Arrangement or any related transaction. Canaccord Genuity understands that the Updated Opinion will be for the use of the Board and will be one factor, among others, that the Board will consider in determining whether to approve or recommend the Amended Arrangement. This Updated Opinion does not address the underlying business decision to proceed with or effect the Amended Arrangement or the relative merits of the Amended Arrangement as compared to other transactions or business strategies that might be available to Robex. In considering fairness from a financial point of view, Canaccord Genuity considered the Amended Arrangement from the perspective of Robex Shareholders generally and did not consider the specific circumstances of any particular Robex Shareholder, including with regard to income tax considerations. The Company has not asked us to address, and this Updated Opinion does not address, the fairness of the Amended Consideration or Amended Arrangement to the holders of any class of securities, creditors or other constituencies of the Company, other than the Robex Shareholders.

Canaccord Genuity believes that its analyses must be considered as a whole, and that selecting portions of the analyses or the factors considered by it, without considering all factors and analyses together, could create a misleading view of the process underlying this Updated Opinion. The preparation of an opinion is a complex process and is not necessarily susceptible to partial analyses or summary description. Any attempt to do so could lead to undue emphasis on any particular factor or analysis. This Updated Opinion should be read in its entirety.

Approach to Fairness

In rendering the Updated Opinion, Canaccord Genuity has performed a variety of financial and comparative analyses based on the methodologies and assumptions that Canaccord Genuity considered appropriate in the circumstances for the purposes of providing its Updated Opinion. Canaccord Genuity has not attributed any particular weight to any specific analysis or factor, but rather has made qualitative judgments based on its experience in rendering such opinions and on the circumstances and Information as a whole.

As part of the financial and comparative analyses and investigations carried out in the preparation of the Updated Opinion, Canaccord Genuity reviewed and considered the items outlined under "Scope of Review". In the context of the Updated Opinion, Canaccord Genuity has considered, among other things, the following principal methodologies:

Net asset value (“ NAV ”) analysis;
Comparable companies analysis;
Precedent transaction analysis;
Trading and historical share price analysis;
Research coverage analysis; and
• Certain qualitative factors.

Net Asset Value Analysis

The net asset value approach considers the value of a company’s key assets on an individual basis which are then aggregated together and adjusted for the liabilities and obligations of the company. Certain of the mining assets of Robex and Predictive were subjected to a discounted cash flow (“ DCF ”) of the estimated future cash flows generated by and used in the properties known as Kiniero, Nampala and Bankan, including opening, reclamation, closure and other expenditures. Other assets and liabilities are reflected as circumstances dictate according to Canaccord Genuity’s judgement, which may include inclusion at invested amount, historical cost, accounting value, or expected realizable value. The life of mine cash flows were based on Robex and Predictive’s internal management projections, and public

==> picture [54 x 29] intentionally omitted <==

market research, with certain adjustments made by Canaccord Genuity to reflect, among other factors, commodity pricing assumptions.

Comparable Companies Analysis

Canaccord Genuity examined the share price to NAV (“ P/NAV ”) and enterprise value (“ EV ”) / in-situ gold resource ounce multiples of select publicly-traded gold development and production companies which Canaccord Genuity considered comparable to each of Robex and Predictive (the “ Peer Groups ”). Based on the Peer Groups, we applied a range of P/NAV and EV/in-situ gold resource ounce multiples to our NAV and Mineral Resource Estimates for each of Robex and Predictive.

Precedent Transaction Analysis

We examined publicly available information to determine the premiums paid in connection with relevant merger of equal transactions involving publicly traded companies listed on the TSX and Australian Securities Exchange (the “ ASX” ) across a range of closing and volume weighted average prices (the “ Precedent Transactions ”). Canaccord Genuity compared the premiums paid in connection with the relevant Precedent Transactions to Robex’s trading on the TSX as at December 9, 2025 .

Trading and Historical Share Price Analysis

Canaccord Genuity reviewed the trading history of Robex and Predictive on the TSX and ASX, including the relative share price performance and historical exchange ratio for Robex against Predictive.

Research Coverage Analysis

Our research coverage analysis examined the value methodologies and associated capital expenditure, operational, metal price and funding assumptions, among others, utilized by research analysts to estimate a NAV of Robex and Predictive.

Certain Qualitative Factors

Within the context of the Amended Arrangement and as it relates to current holders of Robex Shares, Canaccord Genuity also considered qualitative factors including, but not limited to, the potential risks associated with Robex advancing and operating Kiniero and Nampala as an independent company, as well as potential metal price volatility and changes in the macro-economic environment.

The preparation of a fairness opinion is a complex process and is not necessarily capable of being partially analyzed or summarized. Any attempt to do so could lead to undue emphasis on any particular factor or analysis. Canaccord Genuity believes that its analyses must be considered as a whole and that selecting portions of the analyses or the factors considered by it, without considering all factors and analyses together, could create an incomplete view of the process underlying the Updated Opinion. The Updated Opinion should therefore be read in its entirety.

Conclusion

Based upon and subject to the foregoing, and such other matters as Canaccord Genuity considered relevant, Canaccord Genuity is of the opinion that, as of the date hereof, the Amended Consideration to be received by the Robex Shareholders pursuant to the Amended Arrangement is fair, from a financial point of view, to Robex Shareholders.

The Special Committee of the Board of Directors of Robex Resources Inc. Édifice Le Delta 1 2875, boulevard Laurier, bureau 1000 Québec (Québec) G1V 2M2

To the Special Committee of the Board of Directors of Robex Resources Inc.:

Cormark Securities Inc. (“ Cormark Securities ”, “ we ” or “ us ”) understands that Robex Resources Inc. (“ Robex ” or the “ Company ”), Predictive Discovery Limited (“ Predictive ”) and 9548-5991 Québec Inc., a direct wholly-owned subsidiary of Predictive (“ AcquireCo ”), have entered into an arrangement agreement dated October 5, 2025 (the “ Arrangement Agreement ”), pursuant to which, among other things, AcquireCo will acquire all of the issued and outstanding common shares in the capital of Robex (each, a “ Robex Share ”) by way of a statutory plan of arrangement under the Business Corporations Act (Québec), with each holder of Robex Shares (collectively, the “ Robex Shareholders ”) entitled to receive, in exchange for each Robex Share held, 8.667 (the “ Exchange Ratio ”) fully paid ordinary shares in the capital of Predictive (each whole share, a “ Predictive Share ”) (the “ Consideration ”) (the “ Transaction ” or the “ Arrangement ”).

We previously issued you an opinion dated October 5, 2025 (the “ October 5[th] Opinion ”) that, based upon and subject to the factors considered, assumptions made and qualifications stated in such opinion, as of the date of such opinion, the Consideration to be received by Robex Shareholders under the Arrangement is fair, from a financial point of view, to the Robex Shareholders.

Cormark Securities now understands that Robex, Predictive and AcquireCo propose to enter into an agreement (the “ Amending Agreement ”) to amend the Arrangement Agreement providing for, among other things, a decrease to the Exchange Ratio. Accordingly, under the Arrangement Agreement (as amended by the Amending Agreement), each Robex Shareholder will be entitled to receive, in exchange for each Robex Share held, 7.862 Predictive Shares (the “ Amended Consideration ”) (with such transaction as a whole being defined herein as the ” Amended Arrangement ”).

The terms and conditions of, and other matters relating to the Amending Arrangement are provided for in the Amending Agreement and will be described in the addendum (the “ Addendum ”) to the management information circular of Robex dated November 11, 2025 (the “ Circular ”) to be mailed to Robex Shareholders in connection with a special meeting of the Robex Shareholders to be held to consider and, if deemed, advisable to approve the Amended Arrangement.

As a result of the proposed amendments to the Arrangement Agreement, Cormark Securities has been requested by the special committee of the board of directors of Robex (the “ Special Committee ”) to provide an updated opinion to the Special Committee with respect to the fairness, from a financial point of view, of the Amended Consideration to be received by Robex Shareholders pursuant to the Amended Arrangement (the “ Second Fairness Opinion ”).

Except for the following, and subject to modifications as the context requires, the factors considered, assumptions made and qualifications stated in the October 5[th] Opinion remain unchanged (and, except as otherwise defined herein, capitalized terms used herein have the meanings ascribed thereto in the October 5[th] Opinion):

The material representations in Updated Certificate are substantially similar to those described in the October 5[th] Opinion, subject to modifications as the context requires.

The Second Fairness Opinion is rendered as of the date hereof and Cormark Securities disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Second Fairness Opinion which may come or be brought to Cormark Securities’ attention after the date hereof.

PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS NOTES

1. BASIS OF PRESENTATION

The unaudited pro forma condensed consolidated financial statements (the “Pro Forma Financial Statements”) have been prepared by the management of Predictive Discovery Ltd (“PDI”) to illustrate the pro forma impact of the acquisition of Robex Resources Inc. (“Robex”) by PDI (such transaction, the “Arrangement”), under the terms of the Arrangement Agreement dated 5th October 2025, as amended on December 10 2025 (together the “Arrangement Agreement”).

The Pro Forma Financial Statements give effect to the Arrangement as follows:

The unaudited pro forma consolidated statement of profit or loss and other comprehensive income for the 12 months ended 30 June 2025 has been prepared as if the Arrangement had occurred on 1 July 2024.
The unaudited pro forma consolidated statement of financial position has been prepared as at 30 June 2025, as if the Arrangement had occurred on that date.

These statements are provided for illustrative purposes only and do not purport to represent the actual financial position or results of operations had the Arrangement occurred on the dates presented, nor do they project results for any future period.

No adjustments have been made for potential synergies, integration costs, or revenue opportunities that may arise following the Arrangement.

The assumptions and adjustments described in Note 4 reflect adjustments necessary to present Robex’s and PDI’s financial information on a consistent basis under International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

The Pro Forma Financial Statements have been prepared using:

	combined to refect a full 12-month period.

==> picture [142 x 41] intentionally omitted <==

These results have been translated to AUD using the average exchange rate applicable to the 12- month period. (1.107 CAD to AUD)

These Pro Forma Financial Statements should be read in conjunction with the historical financial statements of PDI and Robex, including the accompanying notes. Adjustments have been made only for events that are:

Directly attributable to the Acquisition; and
Factually supportable.

All adjustments reflect estimates and assumptions made by PDI management based on currently available information and are applied consistently with PDI’s accounting policies.

Unless otherwise stated, all amounts are presented in Australian dollars (AUD).

2. MATERIAL ACCOUNTING POLICIES

The Pro Forma Financial Statements have been prepared using the material accounting policies of PDI and Robex, which are consistent with IFRS as issued by the IASB.

3. DESCRIPTION OF THE ARRANGEMENT

On 5 October 2025, PDI entered into an Arrangement Agreement to acquire 100% of the issued shares of Robex. The Arrangement constitutes a business combination under AASB 3 / IFRS 3 Business Combinations , with PDI identified as the acquirer and Robex as the acquiree.

An amendment to the arrangement agreement was signed on 10[th] December 2025, to change the consideration offered under the Arrangement to 7.862 ordinary shares of PDI for each Robex share.

The consideration for the Acquisition will be satisfied entirely through the issuance of PDI ordinary shares to Robex shareholders, together with the transfer of Robex’s convertible securities to PDI at fair value.

Management will apply the acquisition method of accounting, whereby:

Robex’s identifiable assets and liabilities will be recognised at their fair values as at the acquisition date.
The total consideration reflects the enterprise value of Robex, which exceeds the carrying value of its net assets. As part of the purchase price allocation, the excess of consideration over the book value of net assets will be allocated to the fair value uplift of identifiable assets, primarily property, plant and equipment and mineral property interests.

The preliminary estimates of the consideration transferred and net assets acquired, which remain subject to change, are summarised below.

For illustrative purposes in the Pro Forma Financial Statements, the consideration transferred is calculated as:

Shares Issued	Number of	Number of	Fair Value AUD$
	Securities	Securities
	(Robex)	(To be issued)
Shares issued to acquire Robex	276,388,803	2,172,968,769	956,106,258
Fair Value Warrants	12,500,000	98,275,000	26,001,276
Fair Value Options	6,720,000	52,832,640	14,611,181
Fair Value PSUs	5,150,000	40,489,300	17,458,986
Total	300,758,803	2,364,565,709	1,014,177,702

Footnotes:

The fair value of PDI ordinary shares is based on the closing share price of $0.44 AUD per common share on 4 October 2025, being the last trading day prior to the announcement of the Arrangement Agreement.
The fair value of warrants, options, and PSUs has been estimated using the BlackScholes valuation model, based on inputs available as at the valuation date.
For the purposes of the Pro Forma Financial Statements as at 30 June 2025, the consideration transferred assumes that Robex warrants exercised in October 2025 were already included in Robex’s basic share capital. Accordingly, the impact of these exercises is reflected in the total number of Robex shares acquired by PDI and the corresponding consideration transferred. No separate pro forma adjustment has been made to Robex’s balance sheet for the associated increase in cash and equity, as these effects are reflected in the assumed share capital position at the pro forma acquisition date.
All of the values are provisional and are only used for the purposes of preparing these pro forma financial statements. The purchase price accounting will be subject to third party valuation and audit as part of the closing of the arrangement.

4. PRO FORMA ADJUSTMENTS

Pro forma adjustments include:

Recognition of the fair value of Robex’s assets and liabilities, primarily allocated to property, plant and equipment and mineral property interests.
Adjustments to share capital to reflect the PDI shares issued to Robex shareholders.
Elimination of Robex’s historical equity balances, including share capital, reserves, and accumulated losses.
Recording of transaction costs directly attributable to the Acquisition in the consolidated statement of profit or loss.
