Highlights
The following 2020 highlights include a 4-week suspension of operations at the Boungou Mine.

• Signing of definitive agreement with Endeavour
• Consolidated gold production of 81,900 ounces
• Gold sales of $123.2 million
• All-in sustaining cost¹ of $888 per ounce sold
• Operating income of $33.2 million
• Net income attributable to shareholders of the Corporation of $14.1 million or $0.04 per share
• Adjusted net income attributable to shareholders of the Corporation¹ of $20.8 million or $0.06 per share¹
• Cash flow from operating activities before changes in non-cash working capital¹ of $60.0 million or $0.18 per share¹

• SEMAFO provides Endeavour transaction update, including update on timing, mailing of meeting materials for May 28 Special Meeting and Board resolutions passed to apply for delisting from the TSX and Nasdaq Stockholm pending closing of transaction

Benoit Desormeaux, President and Chief Executive Officer of SEMAFO, stated: "Despite a four-week shutdown at Boungou and the implementation of preventive measures against the COVID-19 virus, we delivered a solid first quarter that included a smooth ramp-up of Siou underground to full production. During the quarter, we announced a strategic transaction with Endeavour that continues to receive strong stakeholder support. We remind our shareholders to vote in favour of the transaction at the special shareholder meeting that will be held virtually on May 28. Details on how to attend and vote are provided in the joint circular that has been mailed to shareholders, filed on SEDAR and is available on our website."

Consolidated Operational Overview

Financial results for Boungou and Mana are provided at the end of this press release. In early February 2020, the Boungou plant restarted and processing of the stockpile began.

The year-over-year decrease in gold sales and gold ounces produced and sold is mainly due to the four-week suspension of operations at the Boungou Mine, which was partially offset by the increase in the average realized selling gold price.

The decrease in cash flow from operating activities before changes in non-cash working capital¹ in the first quarter of 2020 compared to the same period in 2019 mainly reflects the four-week suspension of operations at the Boungou Mine.

Update on COVID-19

Over the past months, SEMAFO has implemented a series of protocols to help prevent the spread of the COVID-19 virus among its employees, contractors, suppliers and surrounding communities. At the site-level, these involve sensitising employees, mandatory quarantine for expatriates entering Burkina Faso, temperature screening of new arrivals at travel and site access points, cancelling non-essential travel, increasing sanitation measures and heightening its medical response capacity. Personnel with elevated temperatures or other symptoms are immediately placed in preventive isolation, together with co-workers with whom they may have been in contact.

In parallel, the Corporation instigated early preventive measures to mitigate impact on the supply chain. These include increasing stock levels from suppliers from certain regions and stock levels of key supplies in addition to alternate sourcing of key spare parts and reagents.

Endeavour Transaction Update

As previously announced by the Corporation, in connection with the transaction with Endeavour, a Special Meeting of SEMAFO's shareholders will be held virtually through live audio webcast on Thursday, May 28, 2020 at 09:30 EST. The purpose of the Special Meeting is to seek approval for the acquisition by Endeavour of all the issued and outstanding securities of SEMAFO by way of a Plan of Arrangement under the Business Corporations Act (Québec). Shareholders who wish to attend the virtual Special Meeting must follow the procedures set out in the joint circular which has already been mailed and is available on SEDAR and our website at www.semafo.com.

In addition, SEMAFO was advised today by Endeavour that it has received a notice from the Director of Investments under the Investment Canada Act (the "ICA") pursuant to section 25.2(1) of the ICA indicating that the Minister of Innovation, Science and Economic Development is considering whether to order a national security review of the Transaction under section 25.3(1) of the ICA. Endeavour has advised SEMAFO that it will work with the Director to address any outstanding questions or concerns, although neither Endeavour nor SEMAFO is aware of any reasons for the notice. In particular, while SEMAFO's head office is located in Quebec, it has no operating assets in Canada and its operations are confined to gold production and exploration in Burkina Faso. The Minister has until June 25, 2020 to consider whether to order a review under section 25.3(1) of the ICA. If the Minister issues a notice indicating that no such order for a national security review will be made, and assuming all of the conditions to the Transaction are satisfied or waived, the closing of the Transaction is expected to occur before the end of June 2020.

Finally, in response to the COVID-19 pandemic, the Corporation intends to rely on the exemption provided by AMF Decision No. 2020-PDG-0034 (the "Blanket Relief Order") from the requirement to file its executive compensation disclosure within 140 days following the end of its most recently completed financial year. The Corporation will file its executive compensation disclosure in due course in accordance with the requirements set forth in the Blanket Relief Order, and will hold its annual general meeting of shareholders at the appropriate time.

Delisting from Nasdaq Stockholm

In conjunction with the anticipated closing of the Endeavour transaction, SEMAFO has resolved to apply for delisting of the SEMAFO shares from Nasdaq Stockholm, subject to the satisfaction or waiver of the conditions to the transaction. The last day of trading of the SEMAFO shares on Nasdaq Stockholm will be announced as soon as SEMAFO has been informed thereof by Nasdaq Stockholm.
