Richmont Mines Reports Strong Operational Second Quarter

TSX - NYSE: RIC

Island Gold Mine Delivers Solid Production and Record Low Cash Costs of US$431 per ounce; On-Track to Meet or Exceed Annual Guidance

TORONTO, July 13, 2017 /PRNewswire/ - Richmont Mines Inc. (TSX - NYSE: RIC) ("Richmont" or the "Corporation"), reports strong second quarter results with company-wide production of 31,249 ounces of gold, at cash costs¹ of $725(US$539) per ounce. The strong operational performance was driven by solid production from the Island Gold Mine of 26,110 ounces of gold, at record low cash costs of $580(US$431) per ounce. (All amounts are in Canadian dollars unless otherwise indicated.)

SECOND QUARTER HIGHLIGHTS

• Company-wide production was 31,249 ounces of gold (35,040 ounces sold) for the quarter, primarily driven by another quarter of solid production from the Island Gold Mine of 26,110 ounces of gold (29,534 ounces sold). The mine is now well positioned to achieve, or exceed, the high-end of production guidance for the year of 87,000-93,000 ounces.
• Company-wide cash costs for the quarter were $725(US$539) per ounce, positively impacted by record low cash costs from the Island Gold Mine of $580(US$431) per ounce. The Island Gold Mine remains on-track to meet, or beat, the low end of annual cash cost guidance.
• The Island Gold Mine reported record underground mine productivity of 1,148 tonnes per day, exceeding the late-2018 target rate of 1,100 tonnes per day. The mill averaged a record 940 tonnes per day and is expected to achieve the target rate of 1,100 tonnes per day once the mill expansion is completed in the latter part of 2018.
• Revenues for the quarter were $59.3(US$44.1) million.
• During the quarter, Richmont announced results from the Expansion Case Preliminary Economic Assessment ("PEA") completed on the Island Gold Mine. The PEA confirmed the positive economics of a low cost 1,100 tonne per day underground mine and mill expansion and represents another positive step forward in unlocking the potential of the Island Gold Mine.

"The Island Gold Mine has delivered another solid operational quarter that positions the operation to potentially exceed annual production guidance at record low cash costs. As demonstrated in the recently released PEA, we continue to successfully transform the mine into one of the lowest cost underground gold producers in the Americas as we execute on our disciplined, multi-phased growth strategy," commented Renaud Adams, President and CEO. He continued, "During the balance of the year our focus at the Island Gold Mine will remain on enhancing operational and cost efficiencies, executing on our expansion plan and advancing our strategic delineation and exploration drilling programs. All of these initiatives are supported by our strong balance sheet and our disciplined approach to capital allocation."

Island Gold Mine Highlights

• Production for the quarter was 26,110 ounces of gold (29,534 ounces sold). The mine is now well positioned to achieve, or exceed, the high-end of production guidance for the year of 87,000-93,000 ounces.
• Record low cash costs for the quarter of $580(US$431) per ounce, significantly below annual guidance of $715-765 (US$550-590) per ounce for the year.
• Mill head grade for the quarter was 9.73 g/t gold, partially resulting from lower than planned dilution in development ore. The 2017 mine plan, assuming a 900 tonnes per day scenario, forecasts an overall mill head grade of approximately 8.9 g/t gold for the year.
• Record underground mine and mill productivities for the quarter, averaging 1,148 and 940 tonnes per day, respectively, with lower-grade underground ore stockpiled for future processing, also contributing to the improved overall mill head grade for the quarter.
• During the quarter, long-hole stope mining continued in the first and second mining horizons and development in ore was advanced as planned in the higher-grade third mining horizon. Stoping in the lower grade extensions of the third mining horizon is expected to begin in the fourth quarter.
• The development of the eastern portion of the main ramp system reached a vertical depth of 860 metres at the end of the first quarter, which is in-line with the 2017 development plan. Development of the western portion of the main ramp system was initiated during the second quarter.
• For the first six months, development of the 620 metre and 840 metre level exploration drifts advanced 250 metres and 80 metres, respectively, supporting ongoing exploration and delineation drilling both laterally to the east and at depth.
• During the quarter the transition from underground development contractors to the internal workforce was initiated as planned, this is expected to further reduce development costs over the balance of the year.
• The results of the Expansion Case PEA were released during the second quarter (see May 29, 2017 press release). The study represents another step in a multi-phased approach to unlock the potential of the Island Gold Mine. The PEA confirms the increase in underground mine and mill productivity to 1,100 tonnes per day that will support strong production growth of 22% at low industry cash costs and a robust cash flow stream over an eight-year Phase 1 period, for a low incremental capital cost of $28.2(US$20.9) million. The ramp-up to 1,100 tonnes per day is currently advancing and the operation is anticipated to achieve the target run rate in the latter part of 2018.

Beaufor Mine Highlights

• Production for the quarter was 5,139 ounces of gold (5,506 ounces sold). Production in the quarter was lower than anticipated, primarily due to lower grades mined as higher than expected dilution was reported from one stope located in the Q Zone.
• Cash costs of $1,502(US$1,117) per ounce, higher than annual guidance, are primarily related to lower production achieved for the quarter.
• Underground productivity was 339 tonnes per day. During the quarter, the majority of mining activities were within the main Q Zone, however beginning in Q3 mining flexibility is expected to improve as additional ore will be sourced from new parallel structures.
• During the quarter, the Corporation advanced the review of strategic alternatives regarding the Beaufor Mine and Camflo Mill.
