Predictive Discovery Limited (TSX: PDI) has notified the market of a change to its external audit arrangements. In an announcement dated June 24, 2026, the Perth-based gold explorer and developer advised that Grant Thornton Audit Pty Ltd has been appointed as the company's auditor, following the resignation of PKF Perth. The dual-listed company made the disclosure in accordance with its continuous-disclosure obligations on both the Australian Securities Exchange and the Toronto Stock Exchange.

Auditor changes are a routine part of corporate life, but they are also disclosures that investors are right to read carefully. The identity of a company's auditor, the circumstances of any transition and the regulatory process followed all speak to the integrity of a company's financial reporting. For Predictive Discovery, whose value is closely tied to the advancement of a major West African gold project, sound financial governance is an important part of the investment story. This article sets out what the announcement says, the process behind it and why it matters.

Keys Highlights

• Predictive Discovery Limited (TSX:PDI) announced on June 24, 2026 that it has appointed Grant Thornton Audit Pty Ltd as its new auditor.

• The change follows the resignation of PKF Perth and ASIC's consent to that resignation under the Corporations Act 2001.

• The resignation and replacement appointment took effect immediately, in line with ASIC Regulatory Guide 26 and the relevant statutory provisions.

• A resolution to confirm Grant Thornton's appointment will be proposed at the company's next annual general meeting.

• Predictive Discovery is a gold explorer and developer whose flagship asset is the Bankan Gold Project in Guinea, West Africa.

What the SEDAR+ Announcement Says

The company advised that, in accordance with ASX Listing Rule 3.16.3, Grant Thornton Audit Pty Ltd has been appointed as the auditor of Predictive Discovery Limited. Listing Rule 3.16.3 requires a listed entity to notify the exchange of changes to key officers and advisers, including its auditor, ensuring that the market is kept informed.

The appointment of Grant Thornton follows the resignation of PKF Perth, referred to in the announcement as "PKF." Critically, the resignation was made with the consent of the Australian Securities and Investments Commission (ASIC) under section 329(5) of the Corporations Act 2001. In Australia, a company's auditor cannot simply walk away mid-term; the resignation of an auditor of a public company generally requires ASIC's consent, a safeguard designed to protect shareholders and the integrity of the audit function.

Under section 329(8) of the Corporations Act and ASIC Regulatory Guide 26, the company confirmed that both the resignation of PKF and the replacement appointment of Grant Thornton take effect immediately. The board expressly thanked PKF for its service.

The announcement also noted that, in accordance with section 327C of the Corporations Act, a resolution will be proposed at the company's next annual general meeting to confirm the appointment of Grant Thornton as auditor. This is the standard mechanism by which shareholders ratify an auditor appointed by the directors between annual meetings. The release was authorised for disclosure by the PDI Board and carried the customary TSX disclaimer accompanying the company's Canadian-market communications.

Why This Matters for Investors

For shareholders, the most reassuring aspect of this disclosure is the regulatory rigour visible in the process. The fact that PKF's resignation required, and received, ASIC's consent indicates that the transition followed the formal statutory pathway rather than an abrupt or unexplained departure. The board's acknowledgement of PKF's service, together with the absence of any flagged disagreement in the announcement, points to an orderly handover.

The choice of Grant Thornton, a well-established audit firm, also signals continuity in the quality of financial oversight. For a company whose shares trade on two exchanges and whose investor base spans Australia and Canada, maintaining credible, independent audit arrangements is fundamental. Audited financial statements underpin everything from capital raising to the valuation analysis investors and analysts perform.

The forthcoming shareholder vote to confirm the appointment is worth noting too. While the board has appointed Grant Thornton with immediate effect, the next AGM gives shareholders the formal opportunity to ratify that decision. This layered approach, board appointment followed by shareholder confirmation, is a feature of good governance rather than a red flag. In short, the announcement reads as a procedural, well-managed change rather than an event that alters the company's financial position or prospects.

Company Background

Predictive Discovery Limited is a gold exploration and development company headquartered in Perth, Western Australia, led by Chief Executive Officer and Managing Director Matthew Wilcox. The company is dual-listed, trading on the Australian Securities Exchange and the Toronto Stock Exchange under the same ticker, PDI, on each market.

The company's flagship asset is the Bankan Gold Project in Guinea, West Africa. Bankan has been described as one of the larger gold discoveries to emerge from West Africa in recent years, a region that has become an increasingly important destination for global gold exploration and development capital. West Africa hosts a number of significant gold belts, and discoveries of scale there draw considerable attention from investors and larger mining companies alike.

As a developer advancing a major project from discovery toward potential production, Predictive Discovery sits in the capital-intensive phase of the mining lifecycle. Companies at this stage typically focus on resource definition, technical studies, permitting and securing the financing required to build a mine. Its dual ASX and TSX listings broaden access to two of the world's most active mining-investment markets.

Potential Market Impact

A change of auditor is generally a low-impact event for a company's share price, and there is little in this announcement to suggest otherwise for Predictive Discovery. The disclosure does not touch the company's exploration results, resource estimates, project economics or financing plans, which are the factors that tend to drive sentiment for a gold developer. As such, the immediate market reaction to a procedural auditor transition is usually muted.

Where such disclosures can matter is in the realm of investor confidence. A smooth, regulator-sanctioned auditor change reinforces the perception that a company's governance is in order, which is particularly valuable for a developer that will likely need to access capital markets to advance a large project. By demonstrating that its financial-reporting framework is being maintained to professional standards, the company supports the credibility on which future fundraising and partnership discussions can rest.

For investors tracking ASX: PDI and TSX: PDI, the more meaningful catalysts will remain project-specific, including updates on the Bankan Gold Project, technical studies, permitting progress in Guinea and the broader trajectory of the gold price. The auditor change is best understood as a housekeeping item that keeps the company's governance current.

Key Risks or Things to Watch

Investors considering Predictive Discovery should keep several broader factors in mind, most of which relate to its profile as a single-asset gold developer rather than to the auditor change itself:

• AGM ratification. The appointment of Grant Thornton is subject to confirmation by shareholders at the next annual general meeting, a routine but still-pending step.

• Jurisdictional exposure. The Bankan project is located in Guinea, and operating in West Africa carries country-specific considerations around permitting, fiscal terms and political stability that are common to mining ventures in the region.

• Financing requirements. Advancing a large gold project from discovery to production is capital-intensive, and developers typically must raise significant funding, which can affect dilution and timing.

• Commodity price sensitivity. As a gold-focused company, Predictive Discovery's prospects are closely tied to the gold price, which can be volatile.

• Execution and timeline risk. Project development involves technical studies, construction and ramp-up phases, each of which carries the potential for delays or cost variances common across the mining sector.

These are general considerations inherent to gold development companies and are not consequences of the auditor transition.

Investor Takeaway

The practical message from this announcement is that Predictive Discovery has refreshed its audit arrangements in an orderly, regulator-sanctioned manner. Grant Thornton Audit Pty Ltd steps in as auditor with immediate effect, PKF departs with ASIC's consent and the board's thanks, and shareholders will have the chance to ratify the appointment at the next AGM. There is nothing in the disclosure to suggest a dispute or a problem with the company's accounts.

For shareholders, the takeaway is one of continuity and governance discipline. The change does not alter the investment thesis around Predictive Discovery, which continues to centre on the advancement of the Bankan Gold Project and the broader gold market. Investors can note the transition as evidence of a functioning governance process while keeping their attention on the operational and financing milestones that will ultimately determine the company's path.

Conclusion

Predictive Discovery Limited's appointment of Grant Thornton as auditor, following PKF Perth's regulator-approved resignation, is a textbook example of a routine governance transition handled in line with Australian corporate law and exchange rules. The immediate effect of the change, the statutory consent obtained and the planned shareholder ratification all point to a well-managed process.

For a dual-listed gold explorer and developer with a flagship West African asset, maintaining credible financial oversight is an essential part of building and sustaining investor trust. While the auditor change is unlikely to move the market on its own, it reinforces the governance foundations beneath the company's more consequential work at the Bankan Gold Project. Investors in ASX: PDI and TSX: PDI can file this disclosure under sound housekeeping. This article is for informational purposes only and does not constitute financial advice.
