Board of Directors' Recommendations

The Transaction has been unanimously approved by the boards of directors of each of Fortuna and Roxgold, following, in the case of Roxgold, the unanimous recommendation of a special committee of independent directors. Both boards of directors unanimously recommend that their respective shareholders vote in favour of (i) the Share Issuance, in the case of the Fortuna Meeting and (ii) the Transaction, in the case of the Roxgold Special Meeting.

In connection with the Transaction, officers and directors of Roxgold collectively holding 3.52% of the total Roxgold Shares have entered into voting support agreements with Fortuna, pursuant to which they have agreed, among other things, to vote their Roxgold Shares in favour of the Transaction. Appian Natural Resources Fund, Roxgold's largest shareholder which at April 26, 2021 (the date the Transaction was announced), controlled 13.2% of the issued and outstanding Roxgold Shares, has also provided its support in favour of the Transaction. In addition, officers and directors of Fortuna collectively holding 1.6% of the total Fortuna Shares have entered into voting support agreements with Roxgold pursuant to which they have agreed, among other things, to vote their Fortuna Shares in favour of the Share Issuance.

Subject to obtaining shareholder approval to the Share Issuance and the Transaction at the Fortuna Meeting and Roxgold Special Meeting, respectively, and satisfaction of the other conditions to completion of the Transaction, including final approval of the Court, all as more particular described in the Fortuna Circular and the Roxgold Circular, the Transaction is expected to close in early July 2021.

To be effective, the Share Issuance must be approved by a simple majority of the votes cast on such resolution by Fortuna shareholders present (virtually) or represented by proxy at the Fortuna Meeting. In addition, the Transaction must be approved by (i) at least 66 ⅔% of the votes cast on such resolution by the Roxgold shareholders present (virtually) or represented by proxy at the Roxgold Special Meeting; and (ii) a majority of the votes cast by the Roxgold shareholders (virtually) or represented by proxy at the Roxgold Special Meeting, excluding the votes cast by certain persons in accordance with section 8.1(2) of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions.


Strategic Rationale and Transaction Highlights:

In unanimously determining to recommend the Share Issuance and Transaction to shareholders for approval, the boards of directors of each of Fortuna and Roxgold considered a number of factors as described in the Fortuna Circular and Roxgold Circular, including, but not limited to:

Combination of Quality Assets Creates a premier growth-oriented intermediate gold and silver miner, with four producing mines and anticipated annual gold equivalent combined production of approximately 450,000 ounces. ^{1, 2, 3}

Highly Complementary and Diversified Portfolio Expanded diversified production, development, and exploration platform: four operating mines supporting a robust free cash flow profile, a permitted development project at the feasibility stage, and an extensive growth pipeline of high-upside exploration assets in West Africa and the Americas.

Organic Growth Potential Construction expected to be launched at the S?gu?la Gold Project in the third quarter of 2021; continue the accelerated pace of advanced exploration at the Boussoura Project and on the extensive 250,000-hectare land package in West Africa. Multiple brownfields and greenfields options across the Americas and West Africa.

Geographical Diversification in Mining Jurisdictions Creates a low-cost platform for precious metals production and growth in two premier mining friendly regions.

Bringing Together Two Highly Experienced Management Teams with Track Records of Value Creation in the Americas and in West Africa Fortuna will benefit from the in-region operating experience of key members of Roxgold's team.

Silver Contribution to Revenue Silver production is expected to be largely in-line with its silver producer peer group. Pro Forma Fortuna will continue to pursue opportunities for the discovery and acquisition of quality silver assets in the Americas.

Strong Balance Sheet Pro Forma Fortuna will benefit from significant free cash flow generation, high EBITDA margins, and a stronger balance sheet with significant liquidity and low debt; ⁴ all of this will contribute towards a lower cost of capital and increased funding capacity for the development at the S?gu?la Gold Project and to advance exploration at the Boussoura Project and the larger land package in West Africa.

Fairness Opinions The boards of directors of each of Fortuna and Roxgold, as well as the special committee of Roxgold's board of directors, have each received fairness opinions from their respective financial advisors.

1. Gold equivalent based on the following commodity price assumptions: US$800/oz Au, US$22/0z Ag, US$1,900/t Pb and US$2,300/t Zn.
