Equinox Gold and Calibre Mining Amend Arrangement Agreement in Respect of Proposed Business Combination, Announce Adjournment of Respective Shareholder Meetings, New Meeting Dates Set for May 1, 2025

Vancouver, British Columbia–(April 23, 2025) – Equinox Gold Corp. (TSX: EQX) (NYSE American: EQX) (“Equinox Gold”) and Calibre Mining Corp. (TSX: CXB) (OTCQX: CXBMF) (“Calibre” and collectively the “Companies”) announce that the Companies have amended the arrangement agreement (the “Amended Arrangement Agreement”) pursuant to the proposed business combination previously announced on February 23, 2025 (the “Transaction”).

Under the terms of the Amended Arrangement Agreement, Calibre shareholders will receive 0.35 Equinox Gold common shares for each Calibre Share held (the “New Exchange Ratio”) immediately prior to the effective time of the Transaction. Upon completion of the Transaction, existing Equinox Gold shareholders and former Calibre shareholders will own approximately 61% and 39% of the outstanding common shares of the combined company, respectively, on a fully diluted basis. The New Exchange Ratio represents a 10% premium to the closing price of Calibre shares on the Toronto Stock Exchange on February 21, 2025, the last trading day before the Transaction was announced.

To allow Equinox Gold shareholders and Calibre securityholders time to consider and vote on the Amended Arrangement Agreement, both Equinox Gold and Calibre are adjourning their respective shareholder meetings that were scheduled for April 24, 2025. The Equinox Gold meeting will now be held on May 1, 2025 at 1:30 pm (Vancouver time) and the Calibre meeting will now be held on May 1, 2025 at 10:00 am (Vancouver time). Details regarding how to attend the meetings in person or attend via webcast are included later in the news release.

Greg Smith, President & CEO of Equinox Gold, commented: “We believe this transaction is in the best interest of shareholders of both Equinox Gold and Calibre Mining. Combining these two companies will create a major gold producer with the potential to produce more than 1.2 million ounces of gold per year in the very near term, all from mining-friendly jurisdictions in the Americas and underpinned by production from two world-class Canadian gold mines. We also believe the offer of 0.35 Equinox Gold shares for every Calibre share is full and fair valuation that reflects both the current production and the growth potential of each company.”

Darren Hall, President & CEO of Calibre, commented: “With a focus on operational excellence and execution, the combination of Calibre and Equinox Gold will create more shareholder value together than either could achieve individually. The combined company will be the second largest gold producer in Canada and one of the top 15 gold producers globally. I encourage Calibre shareholders to cast your vote in favour of the transaction.”

Details of the Vote

The record date for determining shareholders eligible to vote at the respective meetings remains March 18, 2025. The deadline for Equinox Gold and Calibre shareholders to return their completed proxies or voting instruction forms has been extended to May 1, 2025 at 10:00 am (Vancouver time) and April 29, 2025 at 10:00 am (Vancouver time), respectively.

The adjournment of the meetings is intended to provide additional time for all shareholders and securityholders to vote on the Transaction, in light of the Amended Arrangement Agreement.

Equinox Gold

At the Equinox Gold meeting, Equinox Gold shareholders will be asked to approve, among other things, the issuance of up to 296,838,303 Equinox Gold common shares (the “Share Issuance Resolution”), which is unchanged from the share issuance resolution disclosed in the management information circular (“Equinox Gold Information Circular”) dated March 21, 2025 that was sent to Equinox Gold shareholders. The Share Issuance Resolution is not being amended to include the additional up to 35,341,282 Equinox Gold common shares that would be issued to reflect the New Exchange Ratio (the “Additional Shares”), since the Transaction is a Public Company Acquisition pursuant to TSX Staff Notice 2018-0005 and the Additional Shares represent less than 25% of the Equinox Gold common shares that Equinox Gold shareholders will be asked to approve pursuant to the Share Issuance Resolution. The issuance of up to 332,179,585 Equinox Gold common shares pursuant to the Transaction (which is on a fully diluted basis) represents approximately 73% of the 456,062,878 issued and outstanding Equinox Gold common shares (on a non-diluted basis) as of the March 18, 2025 record date for the Equinox Gold meeting.

A preliminary assessment of Equinox Gold votes received shows overwhelming approval of the Transaction, with almost 70% of shares voted. Equinox Gold’s board of directors unanimously recommend that Equinox Gold shareholders approve the Transaction by voting FOR the Share Issuance Resolution.

• Equinox Gold shareholders who have already voted their shares in support of the Share Issuance Resolution are not required to take further action.
• Equinox Gold shareholders who have already voted and wish to change their vote can follow the instructions outlined in the Equinox Gold Information Circular that was sent to Equinox Gold shareholders by mail or email.
