Hummingbird Resources plc

("Hummingbird", the "Group" or the "Company")

Extension of PUSU Deadline under Rule 2.6(c) of the Code

On 6 November 2024, the Board of Hummingbird (the "Board") announced that it had received a proposal from Nioko Resources Corporation ("Nioko") and CIG SA ("CIG") for a debt-to-equity conversion by CIG, whereby the principal amount outstanding under the New CIG Loan would be converted into new ordinary shares in the capital of the Company to be issued to CIG's subsidiary, Nioko, at a conversion price of 2.6777 pence per Ordinary Share (the "Debt-to-Equity Conversion"), and possible cash offer for the entire issued ordinary share capital of the Company that it does not hold at a price of 2.6777 pence per Ordinary share (the "Offer Price").

Nioko and CIG are required, by no later than 5.00 p.m. (London time) on 4 December 2024 (the "PUSU Deadline"), to either announce a firm intention to make an offer ("Possible Offer") for Hummingbird in accordance with Rule 2.7 of the Code or announce that they do not intend to make an offer for Hummingbird, in which case the announcement would be treated as a statement to which Rule 2.8 of the Code applies.

Nioko and CIG have confirmed that the due diligence exercise referenced in Hummingbird's announcement on 6 November 2024 is progressing and discussions between Hummingbird, CIG and Nioko remain ongoing.

In accordance with Rule 2.6(c) of the Code, the Board has requested, and the Panel on Takeovers and Mergers (the "Panel") has consented to, an extension to the deadline by which Nioko and CIG are required either to announce a firm intention to make an offer for Hummingbird in accordance with Rule 2.7 of the Code or to announce that they does not intend to make an offer, until 5.00 p.m. (London time) on 3 January 2025 (the "Revised PUSU Deadline"). The Revised PUSU Deadline may only be extended with the agreement of Hummingbird and the Panel in accordance with Rule 2.6(c) of the Code.

In accordance with Rule 2.5(a) of the Code, Nioko reserves the right to make an offer for the Company at a lower value than the Offer Price: (i) with the agreement or recommendation of the Board of the Company; or (ii) if a third party announces a firm intention to make an offer for the Company which, at that date, is of a value less than the value of the Offer Price. If the Company declares, makes or pays any further dividend or distribution or other return of value or payment to its shareholders, Nioko reserves the right to make an equivalent reduction to the Offer Price. Nioko reserves the right to vary the form and / or mix of the consideration it would offer. Nioko further reserves the right to waive any of the pre-conditions to the Possible Offer referred to above or to subject the Possible Offer to additional conditions or pre-conditions.

This statement is being made by Hummingbird with the approval of Nioko and CIG. While discussions are ongoing, there is no certainty that a firm offer will be made, even if any pre-conditions are satisfied or waived. A further announcement will be made as and when appropriate. Shareholders of Hummingbird Resources are strongly advised not to take any action at this time.

Capitalised terms in this announcement, unless otherwise defined, have the same meaning given to them in the announcement issued by the Company on 6 November 2024.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4). Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Takeover Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
