SEMAFO: Record Quarterly Production and Cash Flow from Operations

Development Pipeline Significantly Strengthened with Savary Acquisition

MONTREAL, May 7, 2019 - Semafo Inc. (TSX: SMF) (OMX: SMF) is pleased to announce record production of 102,400 ounces of gold and cash flow from operating activities¹ of $79 million or $0.24 per share² for the quarter ended March 31, 2019. All amounts are in US dollars unless otherwise stated.

Highlight of Q1 2019

• Consolidated gold production of 102,400 ounces
• Cash flows from operating activities¹ of $79 million or $0.24 per share²
• Net income attributable to shareholders of $17.7 million or $0.05 per share
• Acquisition of Savary Gold announced in Q1 and closed April 30, 2019
• Three rigs drilling at Bantou with results expected early June
• Balance sheet remains conservative with net cash and 100% exposure to upside in gold price

Benoit Desormeaux, President and Chief Executive Officer of SEMAFO, states: "My congratulations to the entire team for a record first quarter of 2019.  Both assets performed well and the strong quarterly contribution from Boungou helped to achieve record production and financial performance on a gross and per share basis. Our team has managed this accomplishment while minimizing dilution, maintaining a net cash position and retaining 100% upside to the price of gold. With the Savary acquisition closed, we have greatly strengthened our development asset base and growth profile. Combining Savary with our Bantou property produced a 1,250 km² district scale land package on the prolific Houndé greenstone belt in a country where we have a 20-year history. With our robust cash flow profile, clean balance sheet, and strong development pipeline we have solidified our position as a leading intermediate gold producer and are well positioned to deliver long term shareholder value."

2019 Guidance Reiterated

Our 2019 guidance provided on February 8 remains unchanged. Operations are tracking according to plan and in line with annual and longer-term targets. The one area that may require additional explanation is the all-in sustaining cost (AISC). The quarterly AISC for Boungou and Mana are slightly above the top end of the 2019 AISC guidance range. This was expected and over the course of the remainder of the year, the AISC for both operations will track back into the 2019 guidance range, albeit for different reasons.  At Boungou, the mine plan calls for the strip ratio to decrease over the year with a corresponding reduction in AISC.  At Mana, the mine plan calls for ore in the first half of the year to be sourced exclusively from Wona. Higher grade ore from the Siou North pit will only be available in the second half of 2019. As the average head grade increases at Mana, the AISC will correspondingly decrease.

Siou Underground Continues on Time, on Budget

Underground development at Siou continued to advance well with 2,750 meters completed at quarter-end. The pace of development continues in line with our goal of reaching full production in the first quarter of 2020. At quarter-end, the development continued on budget, with $19.8 million of the total $51.7 million budget incurred. Further, we started grade control drilling with results consistent with the block model. In April 2019, Siou underground was approved by the National Mines Commission and the permit is expected shortly.

Exploration and Development
Bantou

The focus of the exploration in the first quarter was at Bantou where a total of 58 RC (9,188 meters) and 5 core holes (821 meters) were drilled. The Bantou Zone hosts a maiden inferred resource estimate of 361,000 ounces at 5.35 g/t Au. Initially, one drill was active on the Bantou property testing a variety of prospective target areas. During the quarter, we encountered an interesting area approximately two kilometers north of the Bantou Zone. The area was sufficiently interesting to warrant further drilling, and a second drill was mobilized to continue testing the other target areas. Consequently, much of the drilling in the quarter was carried out on this new area. Assays are being compiled and we expect results, along with a geological interpretation, to be released in early June.

A third drill was added at Bantou in the quarter. The focus of the third drill is to test the extensions of the Bantou Zone along strike and at depth. With three active drills at Bantou, we will be increasing the exploration budget and will provide further details in early June.

Boungou

A total of 7,517 meters of reverse-circulation (RC) drilling was completed in the first quarter on the Dangou NE and Dangou Centre targets. The 7,517 meters represent approximately 30% of the total 25,000-meter program, which is designed to test and establish continuity. Although there have been some encouraging intercepts (1 meter at 22.9 g/t Au, 9 meters at 1.36 g/t Au, 4 meters at 3.67 g/t Au, 1 meter at 6.66 g/t Au, and 3 meters at 5.69 g/t Au), an interpretation can only be provided when the full program has been completed towards the end of the year.

Mana

An RC drill program commenced late March on the satellite targets located just north of Siou. Although some results have been returned so far (3 meters at 3.31g/t Au and 5 meters at 2.16 g/t Au), only 1,064 meters have been completed out of a total of 10,400 meters. The overall 2019 Mana exploration program includes 18,600 meters of RC drilling, including 7,600 meters at Pompoi.

Nabanga

A preliminary economic assessment (PEA) study has been initiated following the release of the updated inferred resource estimation at Nabanga (840,000 oz at 7.7 g/t Au). The study remains in progress and, as scheduled, will be released in the third quarter.

Summary

All areas of the business performed well in the first quarter. We look forward to carrying forward the momentum into the second quarter and beyond.
