Deep Drilling Intersects 18.03 g/t over 5.70 metres; Near-Mine Lateral Drilling Intersects 33.32 g/t over 2.60 metres and 9.99 g/t over 6.65 metres

TORONTO, May 5, 2016 /PRNewswire/ - Richmont Mines Inc. (TSX - NYSE MKT: RIC) ("Richmont" or the "Corporation"), is providing an update on the previously announced Island Gold exploration drilling program (Figure 1), which continues to demonstrate the significant potential of the cornerstone Island Gold Mine.

The exploration drilling program commenced in September 2015 and is now focused on three key priorities: 1) Testing the lateral continuity of the known deposit to potentially extend mine life above the 1,000 metre level; 2) following up on gold intersections down plunge that support the potential for an extension of the deposit between the 1,000 and 1,500 metre levels; and 3) testing high-priority regional gold targets elsewhere across the prospective Island Gold property.

"These positive results on the eastern extension along strike, directly adjacent to the main deposit area, could be incorporated into our near-term mine plan. We are also pleased to report significant intersections further east, approximately one kilometer from the main deposit that we will continue to explore." stated Renaud Adams, President and CEO. He continued, "The deep directional drilling program continues to confirm the higher-grade, wider mineralized zones at depth below the 1,000 metre level. We are very encouraged that all of the holes successfully intercepted the mineralized structure and that the average grade and thickness continue to be consistent at depth."

"We are very pleased with the positive drill intercepts from the eastern lateral exploration as they continue to indicate that the mine deposit remains open to the east." stated Daniel Adam, Vice-President, Exploration. He continued, "The deep directional drilling program continues to intersect the main structure with the results to date confirming that the zone is still robust and open in all directions. Our broader exploration initiative across the property has given us some very interesting initial results below the old Kremzar mine, which will support additional drilling in this area. Our aggressive exploration initiatives are meeting with success and we are excited by the potential to identify additional resources along strike, at depth and elsewhere on the larger Island Gold Mine property."

Highlights from the drilling program to date include:

Lateral Exploration (Figure 2)
Exploration drilling in 2015 discovered that the favourable Island Gold mineralized structure extends to the east of the main deposit area above the 1,000 metre level. The current drilling program successfully demonstrates the potential to increase the resource inventory to the east, as well as the potential for vertical extensions of the previously defined resource blocks in the Extension 1 and Extension 2 areas of the mine. The focus remains on further identifying the potential to extend the Phase 1 mine life in this area to the east, along strike of the main deposit and above the 1,000 metre level.

The planned 56,000 metre lateral exploration program is expected to be completed in the second quarter, with approximately 46,800 metres completed to date. Drilling is being conducted from surface (9,500 metres) from the exploration drifts on the 450 and 620 metre levels (36,000 metres), from the 190 metre level (5,500 metres) and from the 340 metre level (5,000 metres). The program is expected to be completed in the second quarter.

Highlights include (all results are reported with estimated true width and high grade capped at 95 g/t gold):

• Hole 620-536-32: 11.14 g/t gold over 2.15 metres
• Hole 620-536-32: 11.14 g/t gold over 2.15 metres
• Hole 620-550-16: 6.22 g/t over 2.28 metres
• Hole 620-550-17: 6.35 g/t gold over 3.29 metres
• Hole 340-580-11: 8.07 g/t gold over 2.07 metres (parallel zone)
• Hole 340-580-11: 15.27 g/t gold over 1.64 metres
• Hole 340-588-01: 17.60 g/t gold over 1.79 metres (parallel zone)
• Hole 340-588-01: 9.99 g/t gold over 6.65 metres
• Hole 340-588-02: 8.37 g/t gold over 1.85 metres (parallel zone)
• Hole 340-588-03: 5.16 g/t gold over 6.93 metres (parallel zone)
• Hole 340-588-03: 11.36 g/t gold over 1.26 metres (parallel zone)
• Hole GD-590-02: 33.32 g/t gold over 2.60 metres
• Hole GD-630-01: 12.84 g/t gold over 0.98 metres

Due to the significantly favourable results from this recent drilling to the east, better access for drilling, and its proximity to the existing mining operations, drilling to test the potential extension to the west of the known Island Gold deposit will be deferred until a subsequent program.

Deep Directional Drilling (Figure 3)
The deep directional drilling program was designed to test the down plunge extension of the deposit between the 860 and 1,500 metre levels and to follow-up on a single deep hole from surface that intersected 19.87 g/t gold over 3.93 metres at a depth of 1,200 metres. The objective of the deep drilling program is to test the deposit at depth and to increase confidence in the vertical extension of the deposit for significant potential resource growth.

High grade gold values continue to be intersected, including 18.03 g/t gold over 5.70 metres, 14.71 g/t gold over 1.53 metres and 11.72 g/t gold over 4.80 metres, which increase our confidence of the interpreted high grade zone at depth. To date, approximately 16,000 metres (15 holes) of the planned 23,000 metres (30 holes) of drilling have been completed, including 3 pilot holes and 12 wedged holes. A fourth drill was added to support the advancement of the drilling program that will focus on targets to the west of the first dyke that marks the limit between the Main Zone and Extension 1 areas. As a result, a further 5,000 metres of drilling have been added to the program, which is expected to be completed in the third quarter.

All of the 15 holes completed to date intersected the main mineralized structure and 60% (9 holes of 15) intersected gold values greater than 4.0 g/t gold over estimated true widths greater than 4.0 metres. The equal weighted average of these 9 holes, considering grades and true width, is respectively 12.04 g/t gold over 5.06 metres.

Highlights include (all results are reported with estimated true width and high grade capped at 95 g/t gold):

• Hole MH2A: 18.03 g/t gold over 5.70 metres
• Hole MH2A-1: 14.71 g/t gold over 1.53 metres
• Hole MH1-5: 11.72 g/t gold over 4.8 metres
• Hole MH3-5: 6.03 g/t gold over 7.07 metres

Regional Surface Exploration (Figure 4)
Drilling completed in the old Kremzar Mine area tested the extension of the previously mined mineralized zone at depth, with 2,655 metres of drilling (3 holes) completed to date. Results confirm the extension of the mineralized quartz veins at depth (Main zone and subsidiary zones) and a significant new gold zone of 9.71 g/t gold over 8.00 metres (core length) was intersected in hole KZ-16-02 at a vertical depth of about 600 metres.

Highlights include:

• Hole KZ-16-01: 36.97 g/t gold over 0.80 metres (core length, subsidiary vein, about 230 metres below the bottom of the ramp)
• Hole KZ-16-01: 27.05 g/t gold over 0.61 metres (core length, subsidiary vein, about 295 metres below the bottom of the ramp)
• Hole KZ-16-01: 6.49 g/t gold over 1.97 metres (core length, subsidiary vein, about 325 metres below the bottom of the ramp)
• Hole KZ-16-02: 9.71 g/t gold over 8.00 metres (core length, subsidiary vein, about 350 metres below the bottom of the ramp), including 20.76 g/t gold over 3.32 metres (core length)
