Transaction Structure and Timing

The Agreement between Equinox Gold and Solaris Copper will see the copper assets transferred by way of an Arrangement under the Business Corporations Act (British Columbia). Following completion of the Arrangement, Equinox Gold’s shareholders, other than any dissenting shareholders, would be issued shares in Solaris Copper so that collectively they would own 60%, with the remaining 40% interest held by Equinox Gold.

The Arrangement involves, among other things, the distribution of common shares of Solaris Copper (the “Solaris Copper Shares”) to Equinox Gold shareholders such that each shareholder will hold: (i) one new common share of Equinox Gold for each common share of Equinox Gold held on the effective date of the Arrangement; and (ii) one-tenth of a Solaris Copper Share for each common share of Equinox Gold held on the effective date of the Arrangement. Equinox Gold warrants, options and restricted share units will also be adjusted pursuant to the Arrangement as described in more detail in the Circular.

Equinox Gold received an interim order from the Supreme Court of British Columbia authorizing the Company to call the Meeting to approve the Arrangement. Equinox Gold shareholders of record as of June 18, 2018, will be able to vote on the Arrangement at the Meeting to be held on July 26, 2018. To be effective, the Arrangement must be approved by a special resolution passed by at least 66⅔% of the votes cast by Equinox Gold shareholders present in person or represented by proxy at the Meeting, which shareholders are entitled to one vote for each Equinox Gold share held.

After closing of the Arrangement, new Equinox Gold shares and certain of Equinox Gold’s warrants will continue trading on the TSX Venture Exchange in Canada under the symbols EQX and EQX.WT, respectively, and on the OTC Market in the United States under the symbols EQXGF and EQXWF, respectively. Solaris Copper Shares will not be listed on any stock exchange after closing of the Arrangement, but the company will be a reporting issuer and will comply with its continuous disclosure obligations including press releases and financial reporting.

Additional details of the Arrangement are included in the Circular to be mailed to shareholders on or about June 28, 2018.
