Dundas Minerals Limited (ASX:DUN) has announced that 2,000,000 restricted options under the code DUNAL expired unexercised on 2 July 2026, reducing the company's total unquoted equity securities. These options, which had no exercise price and were restricted, lapsed without conversion or exercise, meaning no payment was made by Dundas Minerals related to their expiry. Following this, the company’s quoted issued capital remains at 235,025,183 fully paid ordinary shares. This update lowers the potential dilution risk from this specific tranche of securities for investors monitoring the capital structure.

Details on the Expiry of DUNAL Restricted Options on 2 July 2026
The 2,000,000 DUNAL options were restricted securities with an expiry date of 2 July 2026. As per the company’s announcement lodged on 3 July 2026, these options expired without being exercised or converted. Being restricted and unquoted, these options did not affect the company’s quoted share count upon expiry.
Dundas Minerals confirmed that no payment was made by the company in relation to the cessation of these options, consistent with standard practice where holders lose rights without compensation when options lapse unexercised. The company did not provide additional details on the holders or reasons for non-exercise.
Quoted Share Capital Remains at 235,025,183 Fully Paid Ordinary Shares
Following the lapse of the DUNAL options, Dundas Minerals’ quoted share capital remains unchanged at 235,025,183 fully paid ordinary shares (ASX:DUN). This figure forms the basis for the company’s market capitalisation on the ASX. Since the expired options were unquoted, their lapse does not alter the quoted share count.
The unchanged share count indicates no new shares were issued in connection with this expiry. Public information does not indicate any immediate share price impact from this event.
Remaining Unquoted Options Held by Dundas Minerals Post-DUNAL Expiry
Despite the DUNAL tranche expiry, Dundas Minerals continues to hold a significant portfolio of unquoted options across multiple classes. The company update lists near-term options such as DUNAK (2,000,000 options expiring 1 July 2026), DUNAO (500,000 options at $0.25, expiring 1 July 2026), and DUNAP (500,000 options at $0.30, expiring 1 July 2026).
Longer-term options include DUNAS (15,000,000 options at $0.033, expiring 16 June 2029), DUNAT (15,000,000 options at $0.0374, expiring 16 June 2029), DUNAA (14,000,000 options at $0.06, expiring 6 May 2029), and DUNAB (8,000,000 options at $0.10, expiring 6 May 2029), among others. The full register comprises over 88 million unquoted options, representing a significant potential dilution source depending on market conditions and exercise decisions.
Upcoming Option Expiries in July 2026 to Watch
The expiry of DUNAL options is not the only imminent cessation event. The DUNAK tranche, with 2,000,000 restricted options expiring on 1 July 2026, precedes the DUNAL expiry by one day. If these options have also lapsed unexercised, Dundas Minerals may need to file a further Appendix 3H notification.
Additionally, DUNAO and DUNAP, each comprising 500,000 options at exercise prices of $0.25 and $0.30 respectively, expire on 1 July 2026. If these options have expired without exercise, further cessation announcements may follow. Investors should monitor ASX filings for updates on these tranches.
Significance of Restricted Options in Dundas Minerals’ Capital Structure
Restricted options like DUNAL and DUNAK are typically issued under employee incentive plans or to founders, directors, or early investors, and are not tradable on the ASX. They do not appear in the quoted share count until exercised and converted into ordinary shares.
Options expiring unexercised may reflect factors such as the share price being below the option’s value threshold, unmet vesting conditions, or the holder’s choice not to exercise. The DUNAL options had no disclosed exercise price, and the company provided no further commentary on their expiry.
Potential Dilution from Dundas Minerals’ Longer-Dated Options
While the expiry of DUNAL options has limited immediate impact on the 235-million share register, the broader unquoted options portfolio is significant. The largest tranches are DUNAS and DUNAT, each with 15,000,000 options at exercise prices of $0.033 and $0.0374 respectively, both expiring in June 2029. Together, these represent 30 million potential new shares if fully exercised.
Other longer-dated tranches include DUNAAA and DUNAAB (5,000,000 options each at $0.08 and $0.12, expiring April 2030), and DUNAV and DUNAW (5,000,000 options each at $0.08 and $0.16, expiring December 2029 and December 2030). Exercise of these options depends on Dundas Minerals’ future share price and exploration progress.
No Payment Made by Dundas Minerals on DUNAL Option Expiry
The company explicitly confirmed no consideration was paid upon the expiry of the 2,000,000 DUNAL options. This is standard when options lapse unexercised—no buyback or compensation occurs. The company simply updates its register to reflect the lapse.
This event has no cash flow impact on Dundas Minerals. Had the options been exercised, proceeds would have been received based on any exercise price. Since the DUNAL options had no disclosed exercise price, their expiry’s financial impact is minimal aside from reducing potential dilution. No further financial details were provided.
Overview of Dundas Minerals and Its ASX Securities
Dundas Minerals Limited is an ASX-listed mineral exploration company trading under ticker DUN. Its quoted securities consist solely of fully paid ordinary shares, currently totaling 235,025,183 following this expiry. The company also holds a large number of unquoted options with varying exercise prices and expiry dates, typical for an early-stage exploration firm.
No operational, exploration, or strategic updates accompanied this securities cessation notice, which is a regulatory filing under ASX Listing Rules (Appendix 3H). For broader company information, investors should consult separate operational announcements and financial reports.
Investor Considerations for Dundas Minerals’ Capital Structure
Investors should closely monitor the status of remaining July 2026 option tranches. If DUNAK, DUNAO, and DUNAP have also expired unexercised, the unquoted options register will shrink further. Conversely, if exercised, the quoted share count would rise and be reflected in separate Appendix 2A filings.
Medium-term attention should be given to any new option issuances under incentive plans, which could increase dilution risk. With exercise prices ranging from $0.033 to $0.30 and expiries extending to April 2030, the capital structure presents multiple layers of potential future dilution. Upcoming cessation or exercise notifications will provide key insights into the company’s evolving capital position.
