How to vote

Shareholders can vote by either:

attending the Meeting and voting in person or by attorney or, in the case of corporate Shareholders, by appointing a corporate representative to attend and vote; or
appointing a proxy to attend and vote on their behalf using the Proxy Form accompanying this Notice of Meeting and by submitting their proxy appointment and voting instructions in person, by post, electronically via the internet or by facsimile.

Voting in person (or by attorney)

Shareholders, or their attorneys, who plan to attend the Meeting are asked to arrive at the venue 15 minutes prior to the time designated for the Meeting, if possible, so that their holding may be checked against the Company's share register and their attendance recorded. To be effective a certified copy of the Power of Attorney, or the original Power of Attorney, must be received by the Company in the same manner, and by the same time as outlined for proxy forms below.

Questions at the Meeting

Please note, only Shareholders may ask questions once they have been verified. It may not be possible to respond to all questions. Shareholders are encouraged to submit questions prior to the Meeting (please see below).

Submission of written questions to the Company in advance of the Meeting

A Shareholder who is entitled to vote at the meeting may submit a written question to the Company in advance of the Meeting at [email protected]. We ask that all pre-Meeting questions be received by the Company no later than 19 May 2026.

Voting by a Corporation

A Shareholder that is a corporation may appoint an individual to act as its representative and vote in person at the Meeting. The appointment must comply with the requirements of section 250D of the Corporations Act. The representative should bring to the Meeting evidence of his or her appointment, including any authority under which it is signed.

Voting by proxy

A Shareholder entitled to attend and vote is entitled to appoint not more than two proxies. Each proxy will have the right to vote on a poll and also to speak at the Meeting.
The appointment of the proxy may specify the proportion or the number of votes that the proxy may exercise. Where more than one proxy is appointed and the appointment does not specify the proportion or number of the Shareholder's votes each proxy may exercise, the votes will be divided equally among the proxies (i.e. where there are two proxies, each proxy may exercise half of the votes).
A proxy need not be a Shareholder.
The proxy can be either an individual or a body corporate.
If a proxy is not directed how to vote on an item of business, the proxy may generally vote, or abstain from voting, as they think fit.
Should any resolution, other than those specified in this Notice, be proposed at the Meeting, a proxy may vote on that resolution as they think fit.
If a proxy is instructed to abstain from voting on an item of business, they are directed not to vote on the Shareholder's behalf on the poll and the Shares that are the subject of the proxy appointment will not be counted in calculating the required majority.
Shareholders who return their Proxy Forms with a direction how to vote, but who do not nominate the identity of their proxy, will be taken to have appointed the Chair of the Meeting as their proxy to vote on their behalf. If a Proxy Form is returned but the nominated proxy does not attend the Meeting, the Chair of the Meeting will act in place of the nominated proxy and vote in accordance with any instructions. Proxy appointments in favour of the Chair of the Meeting, the secretary or any Director that do not contain a direction how to vote will be used, where possible, to support each of the Resolutions proposed in this Notice, provided they are entitled to cast votes as a proxy under the voting exclusion rules which apply to some of the proposed Resolutions. These rules are explained in this Notice.
To be effective, proxies must be received by 10:00am (AWST) on Tuesday, 19 May 2026. Proxies received after this time will be invalid.
Proxies may be lodged using any of the following methods:
By internet:

EXPLANATORY MEMORANDUM

This Explanatory Memorandum is intended to provide Shareholders with sufficient information to assess the merits of the Resolutions contained in the accompanying Notice of General Meeting of the Company.

Certain abbreviations and other defined terms are used throughout this Explanatory Memorandum. land abbreviations are set out in the Glossary to the Explanatory Memorandum.

1 Resolution 1 – Change of Name of the Company

Since December 2014, the Company's name has been Ardiden Ltd, and during that time the Company's main undertakings and principal focus have been gold exploration at its 100% owned Pickle Lake Gold Project in north-west Ontario, Canada.

In December 2025, the Company completed its merger with Lac Gold Limited ACN 678 715 985, the owner of the Rouyn Gold Project in Québec, Canada (Rouyn). Following completion, Lac Gold Limited was converted to a proprietary company limited by shares, with the Company being the sole shareholder, and has changed its name to Lac Gold Holdings Pty Ltd.

The merger provides a foundation for building a focused Canadian gold company capable of advancing two high-quality assets, whilst delivering scale, optionality and flexibility. As the Company enters the next phase of its development, it is well positioned with a strong cash position, flexible financing arrangements at Rouyn and an experienced Board and management team with a proven track record in exploration, project development and capital markets.

The Company has recently announced its first drill results at Rouyn and expects to complete approximately 15,000 metres of diamond drilling across multiple targets during its first drilling program in 2026.

With an encouraging start to the Company's inaugural drilling campaign at Rouyn and a demonstrated potential for continued growth within the existing mineralised system as announced to the ASX on 27 March 2026, the Board has determined that it is appropriate to change the Company's name to "Lac Gold Limited".

The Board will also request that ASX changes the Company's ASX listing code from "ADV" to "LAC" after the change of name takes effect. The code "LAC" has been reserved by the Company.

Section 157(1)(a) of the Corporations Act provides that a company may change its name if the company passes a special resolution adopting a new name. For a special resolution to be passed, at least 75% of the votes validly cast on the resolution by shareholders present and eligible to vote (in person, by proxy, by attorney, or in the case of a Member which is a corporation, by representative) (by the number of shares) must be in favour of the resolution.

If the Resolution is passed, the change of name will take effect when ASIC alters the details of the Company's registration. The proposed name has been reserved by the Company and if the resolution is passed, the Company will lodge a copy of that special resolution with ASIC in order to effect the change.

If the Resolution is not passed, the Company will not be able to change its name and will remain as Ardiden Ltd.

The Company also seeks approval under section 136(2) of the Corporations Act to amend the Company's Constitution to reflect the change of name.

The Board recommends that Shareholders vote in favour of the Resolution.

The Chair of the Meeting intends to vote all available proxies in favour of the Resolution.
