Richmont Mines Inc.("Richmont" or the "Corporation"), is pleased to announce that based on the positive results reported from the Phase 1 exploration drilling program, a strategic Phase 2 exploration drilling program has been launched at the Island Gold Mine. The Corporation is also providing a final update on the Phase 1 drilling program (Figure 1), which continues to demonstrate the potential of the cornerstone Island Gold Mine. (All amounts are in Canadian dollars unless otherwise indicated).
The Phase 1 exploration drilling program commenced in September 2015 and 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 that support the potential for a down plunge 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.
The results from the Phase 1 drilling program have met our objectives, which has supported the launch of an aggressive Phase 2 exploration program of up to 142,000 metres that will be completed over the next 18 to 24 months. The primary objective of the Phase 2 program is to expand the existing resource inventory laterally along strike, mainly to the east of the main deposit, with a goal of extending mine life above the 1,000 metre level that could support the potential expansion scenarios currently under review, as well as to identify the next million-plus ounces of high-grade inferred resource at depth, between the 1,000 and 1,500 metre levels.
"Drilling to date has identified the potential for high-grade resource blocks in the eastern lateral extension that could add incremental ounces to the near-term production plan, support potential expansion opportunities and increase mine life. The success of the deep directional drilling program increases our confidence in the potential to add another million or more, high-grade ounces at depth, which could support medium-to-longer term production growth opportunities." stated Renaud Adams, CEO. He continued, "The Phase 2 program will continue to focus on expanding our global resource inventory with a target of adding inferred ounces both laterally and at depth by the end of the year, with an ultimate goal of unlocking the multi-million ounce potential of the Island Gold Mine."
PHASE 1 EXPLORATION DRILLING PROGRAM UPDATE
Recent highlights from the Phase 1 exploration drilling program include:
Lateral Exploration (Figure 2)
Approximately 50,100 metres of the Phase 1 lateral exploration program (east and west) have been completed, including 16,440 metres from surface, 23,850 metres from the 450 and 620 metre levels, 2,612 metres from the 190 metre level and 7,170 metres from the 340 metre level.
Recent highlights include (all results are reported with estimated true width and high grade capped at 95 g/t gold):
- Hole 620-543-34: 17.41 g/t gold over 2.27 metres
- Hole 620-556-04: 21.00 g/t over 2.78 metres
- Hole GD-590-05: 10.55 g/t gold over 2.46 metres
The Phase 1 lateral exploration program has successfully identified a potential resource block located approximately 300 metres east of the main deposit as well as a second contiguous mineralized sector identified 800 metres east of the main deposit, which demonstrates the potential to increase the resource inventory to the east of the main deposit.
Phase 1 Deep Directional Drilling (Figure 3)
The Phase 1 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 over 3.93 metres at a depth of 1,200 metres. High grade gold values over wide zones continue to be intersected, confirming the interpreted high grade zone at depth. Approximately 21,700 metres of the Phase 1 directional drilling program have been completed, including five pilot holes and 15 wedged holes. All of the holes drilled to date have intersected the main mineralized structure.
Recent highlights include (all results are reported with estimated true width and high grade capped at 95 g/t gold):
- Hole MH1-6: 18.63 g/t gold over 6.60 metres
- Hole MH1-7: 9.11 g/t gold over 4.12 metres
- Hole MH3-6: 12.49 g/t gold over 2.19 metres
- Hole MH4-1: 6.36 g/t gold over 5.84 metres (parallel zone to the main C Zone)
Phase 1 drilling has also identified a potential new high-grade resource block located in the eastern down plunge extension between the 900 and 1,250 metre levels, which shows similar geological characteristics as the main C Zone structure. The weighted average grade of the 20 holes located within the potential inferred resource area (16 from deep directional drilling and 4 from previous drilling programs) is 10.85 g/t gold (capped at 95 g/t gold) over an average true thickness of 4.35 metres. This compares to the main million ounce discovery that has an average resource grade of 10.73 g/t gold (capped at 95 g/t gold) over a 4.5 metre true width.
Regional Surface Exploration (Figure 4)
A 7,500 metre regional exploration program was initiated in 2015 to test the east and west regional extensions of the Island Gold deposit along strike as well as for new deposits within the Goudreau shear zone. The Phase 1 program included drilling in the former Kremzar Mine area, which tested the extension of the previously mined mineralized zone at depth, with 3 holes completed to date. Results to date confirm the extension of the mineralized quartz veins at depth in 2 of the holes (main zone and subsidiary zones). To date, a total of approximately 4,000 metres of drilling have been completed with the remaining 3,500 metres to be incorporated into the Phase 2 drilling program. Ongoing drilling will also focus on the previously identified high-priority gold targets located elsewhere on the highly prospective 77 km2 Island Gold property.
PHASE 2 EXPLORATION PROGRAM (Figure 5)
The Phase 2 exploration program will build on the success of the Phase 1 program and will focus on three key priorities over the next 18 to 24 months: 1) continuing to test the lateral continuity of the known deposit to the east of the main deposit to potentially add new resource blocks with the overall objective of extending mine life above the 1,000 metre level; 2) to identify the next million-plus ounce, high grade inferred resource in the vertical extension of the deposit between the 1,000 and 1,500 metre levels; and 3) continuing to test high priority regional gold targets across the prospective Island Gold property.
Approximately 39,000 metres ($7 million) of the approximately 142,000 metre Phase 2 drilling program is expected to be completed over the balance of the year. (Refer to Table 2 for additional details of the Phase 2 drilling program).
Eastern Lateral Drilling Program (Figure 5)
The Phase 2 eastern lateral drilling program will follow up on the potential addition of new resource blocks located east of the main deposit that were identified as part of the Phase 1 program, as well as continue to test the main mineralized structure laterally along strike above the 1,000 metre level.
Approximately 9,000 metres of an overall 42,000 metres of drilling is expected to be completed over the balance of the year, including approximately 3,000 metres of infill drilling (50 metre drill spacing), to potentially define an inferred resource block between the 500 and 750 metre levels located approximately 300 metres east of the main deposit.
One conventional surface drill and one underground drill from the 340 metre level are currently drilling in the target area. Should infill drilling confirm the potential for a new inferred resource, the 620 metre exploration drift will be extended and infill drilling would then be transitioned to underground drilling from the 620 metre exploration drift.
Due to the favourable results from the Phase 1 drilling to the east, including better access for drilling and proximity to the existing mining infrastructure, drilling to test the potential extension to the west of the known deposit will be deferred until further analysis is complete.
Deep Drilling Program (Figure 5)
The objective of the Phase 2 deep directional program is to continue to test the significant potential of the vertical extension of the main deposit between the 1,000 and 1,500 metre levels with the overall objective of adding the next million-plus ounces of high-grade inferred resources.
Approximately 27,000 metres of an overall 80,000 metres of drilling, including 5,000 metres of infill drilling (50 metre drill spacing), is estimated to be completed over the balance of the year. Four surface directional drills and two surface conventional drills (infill drilling) are currently drilling in the target area. The objective of the deep infill program is to define a potential inferred resource block that was identified through the Phase 1 program, which is located in the eastern down plunge extension of the C Zone between the 1,000 and 1,500 metre levels. The infill drilling will transition to underground drilling once access to the 860 metre drift has been established.
The complete 18 to 24 month deep drilling program will consist of exploring the western and eastern down plunge corridors between the 1,000 and 1,500 metre programs, as well as infill drilling for the potential conversion to inferred high-grade resources at depth that could potentially support additional expansion opportunities and extend mine life.
Regional Program
Approximately 3,000 metres of an overall 20,000 metre drilling program are expected to be completed in 2016. The Phase 2 regional drilling program will continue to evaluate the potential extension of the mineralization below the Kremzar mine as well as the previously identified high-priority gold targets located elsewhere on the highly prospective 77 km2 Island Gold property.
