2020 GUIDANCE

• Restart of the Boungou plant and initial three-month production of 42,000 - 46,000 ounces expected from processing of stockpiles at an AISC of between $530 and $560 per ounce
• Phase two of the Boungou plan includes a Q4 2020 mining restart for production of between 88,000 and 104,000 ounces at AISC of between $745 and $795 per ounce
• Mana is expected to produce between 185,000-205,000 ounces of gold from Siou underground and the Siou and Wona open pits

Benoit Desormeaux, President and Chief Executive Officer of SEMAFO, stated: " Despite a challenging year, we achieved a solid operational performance at Boungou in 2019 while concurrently producing at Mana and progressing development of Siou underground on time and on budget. We have had a positive start to 2020 with the restart of the Boungou plant to process the stockpiles. Mana is expected to deliver another strong year and to increase cash flow with the successful ramp-up of Siou underground. The Bantou Project inferred resource positions us well for reaching this year's resource goal of 2.5M and 3.0M ounces and demonstrates the potential of the district scale land package. We remain deeply grateful to our employees, contractors and suppliers whose resilience and engagement have contributed to these achievements."

2020 Exploration

An initial exploration budget of $7 million has been set for 2020 on our three priority properties - Bantou ($4 million), Mana ($2 million) and Boungou ($1 million).

Bantou

At Bantou, the initial $4-million exploration program will involve a 19,300-meter drill program that is a continuation of last year's program on the properties and designed to test prospective areas outside of the existing inferred resources. We remain committed to our resource goal of 2.5 - 3.0 million ounces by the end of 2020.

This initial budget is likely to increase as the exploration program moves outside the existing zones and follows up interesting intersections like 14.6 g/t Au over 21 meters at Tiébi. Highlights of best results obtained in the fourth quarter are shown in Table 1.

Table 1 - Highlights from Bantou Q4 2019 Exploration*

Boungou

The $1-million exploration program at Boungou for 2020 comprises 3,000 meters of RC drilling and has the objective of identifying new near-mine resources. Expansion of the program is contingent on an improvement in regional security. Starting in the second quarter, the RC program will follow up last year's suspended work.

Mana

At Mana, a $2-million budget has been established to follow up targets identified by the geologic review carried out by an external consulting firm last year. The bulk of the 3,800-meter RC drill campaign will be carried out on three different areas around Siou. We will also be conducting an underground drill program to test if the mineralization extends at depth below the existing underground reserves.

Mining Operations

The following includes a 7-week suspension at Boungou in 2019. As commercial production commenced on September 1, 2018, the comparative figures for Boungou Mine only include four months of operations at the Boungou Mine in 2018.

Grade in 2019 increased, compared to 2018, to average 6.65 g/t Au, as the mine plan reached higher-grade zones. Due to the higher grade, the all-in sustaining cost¹ was $497 per ounce sold compared to $596 per ounce sold in 2018. Recoveries also improved during 2019 to reach 96%, a 2% improvement compared to 2018. As at December 31, 2019, the stockpile holds 1.1 million tonnes at an average grade of 3.4 g/t Au, representing approximately ten months of mill feed.

Mana, Burkina Faso

Mining Operations

Following a pit wall failure in the Wona pit in August 2019, processing of ore at Mana was suspended for a 10-week period. Subsequently, mining operations focused on stripping activities at the Siou and Wona open pits and on development of Siou underground.

In 2019, the ore mined from the open pit decreased and the strip ratio was higher compared to 2018, given our focus on development activities due to the pit wall failure at Mana. The ore processed and gold ounces produced and sold decreased compared to 2018, following the suspension of processing activities at the Mana Mine. Extraction of ore from Siou underground commenced in the fourth quarter 2019 providing 99,600 tonnes of ore at 4.6 g/t Au. In 2019, gold sales amounted to $179,992,000 compared to $229,713,000 in 2018. The variation between gold ounces sold and gold ounces produced is due to the timing of delivery. The lower mining operations expenses are mainly due to the focus on stripping activities. The decrease in depreciation of property, plant and equipment is due to the lower gold ounces sold compared to 2018.

Siou Underground Development

In the fourth quarter of 2019, underground development prior to production continued on time and on budget. First production occurred in December in line with reaching full production of 2,000-tpd in the first quarter of 2020.

In 2019, we decided to take advantage of available equipment and our mining contractor's productivity to get ahead of 2020 grade control drilling and mine development plans. As a result, by the end of 2019, we had grade-control drilled 50% of the orebody and developed up to 1,200 meters over our 2019 plan.

2019 Reserves and Resources - as at December 31, 2019

As at December 31, 2019, total proven and probable mineral reserves stood at 2,640,100 ounces of gold. Measured and indicated mineral resources increased by 9% to 3,302,500 ounces. Inferred mineral resources increased by 86% to 3,977,800 ounces compared to year-end 2018 mainly due to an increase at the Bantou Project.

Changes in reserves are net of 2019 depletion due to production. All mineral resources reported are exclusive of mineral reserves. Mineral reserves and resources reported at Mana and at Boungou were estimated using a gold price of $1,200 and $1,400 per ounce, respectively. Mineral resources at the Bantou and Nabanga Projects were estimated using a gold price of $1,500 per ounce.

Boungou Mine

Total proven and probable reserves at Boungou were 10.3 million tonnes averaging 3.72 g/t Au for 1.2 million ounces of gold in 2019, compared to 10.9 million tonnes at 3.94 g/t Au for 1.4 million ounces in 2018. The decrease is due to depletion as Boungou Mine produced a total of 205,200 ounces in 2019. Total measured and indicated ("M&I") resources increased by 60% to 5.8 million tonnes at 3.25 g/t Au for 0.6 million ounces. The updated 2019 M&I resource is in-pit constrained and now incorporates remaining ounces at a cut-off grade of 2.0 g/t Au.

Mana

At year-end 2019, Mana's mineral reserves totalled 15 million tonnes at an average grade of 2.91 g/t Au for 1.4 million ounces, compared to 16 million tonnes averaging 2.96 g/t Au for 1.5 million ounces in 2018. Mana's mineral resources remained constant at 43.6 million tonnes at an average grade of 1.92 g/t Au for 2.7 million ounces.

Bantou Project

At the end of 2019, the Bantou Project hosted an inferred mineral resource estimate of 51 million tonnes at 1.37 g/t Au for 2.2 million ounces of gold. The Bantou Project, which is located approximately 170 kilometers south of the Mana Mine in Burkina Faso, comprises three groups of deposits: Bantou, Bantou Nord and Karankasso.

The mineral resources at Bantou Project were estimated using a gold price of $1,500 per ounce. For further details, refer to the February 24, 2020 press release.

Yactibo (Nabanga Deposit)

Inferred resources at the Nabanga deposit remain unchanged at 3.4 million tonnes at 7.69 g/t Au for 841,000 ounces of contained gold.
