TORONTO, ONTARIO--(Marketwired - Sept. 16, 2015) - Richmont Mines Inc.Island Gold Mine property that will test the east and west extensions of the Island Gold deposit along strike as well as for new deposits within the regional Goudreau shear zone, which hosts the mine's current operations. The updated program also includes drilling of selected high-priority gold targets identified by the exploration team, based on their previous work and compilations, elsewhere on the highly prospective 77 km2 Island Gold Property. The exploration drilling began earlier this year with 1,800 metres completed at the end of the second quarter. The program will follow up on high quality gold targets well characterized by our exploration team, while leveraging more advantageous drilling costs.

The Island Gold mine is located in an area of northeastern Ontario that is underexplored within the context of Canada's long mining history. However, within a 15 km radius of the current operations are four past producing mines, three of which occur within the same regional Goudreau shear zone that hosts the Island Gold mine. This underexplored region with proven favourable geology, a lack of regional exploration data at depth and the success we have had in establishing the significant million ounce high-grade resource below our Island Gold Mine, are all evidence of very promising, yet untested potential on the Island Gold land package.

"While we also recently announced an aggressive 23,000 m deep directional drilling program with the goal of a near-term expansion of our resources at depth below our existing operations, we also believe that there is excellent upside exploration potential for new deposits along strike, and elsewhere on our large Island Gold property. With Island Gold's production and development proceeding as planned, infill and definition drilling underway, and our recently-announced deep directional drilling to commence shortly, we see this step-out exploration as an important step to increase long-term shareholder value through potential resource expansions along strike as well as new discoveries elsewhere on the property." commented Mr. Renaud Adams, President and CEO.

The remaining 17,000 metres of the updated surface exploration drilling program will consists of approximately 30 to 35 holes and will be focused on six key areas, detailed in the figure attached.

Figure 1: Island Gold Mine - Surface Geology - 2015 Planned Exploration Program

1.  Western Shear Extension: This area extends from the western edge of the

    current Island Gold resource, west for a distance of approximately one

    kilometre, to the claim boundary with Argonaut. A few holes have

    previously tested this zone from surface and underground, encountering

    positive results. One hole, recently completed from underground assayed

21.16 g/t Au (17.33 g/t Au cut at 75 g/t) over 4.78 metres (core length,

true width not yet known) at a vertical depth of 674 metres. The current

program will continue the drill testing of this potential from

underground and from surface. The proximity to the mine workings would

likely facilitate development of this area from the existing underground

    infrastructure, if an economic resource can be identified. A total of 4

    surface holes totalling 2,500 metres are budgeted for the area.



2.  Eastern Shear Extension: The Island Gold property includes a further

    five kilometre strike length of the favourable Goudreau shear zone to

    the east of the Island Gold Mine. A total of 13 holes totalling 7,000

    metres are budgeted for this area. The targets along the shear include:



    a.  One target area is located only 600 metres east of the current

        workings. A few drill holes testing this near-surface area from

        surface in 2010 intersected positive results. If successful, this

        area could likely be developed from the existing mine workings.



    b.  Further to the east along the shear, approximately 1.5 km from the

        current mine is a target where a 2010 drill hole intersected

        encouraging gold mineralization.



    c.  The past producing Edwards and Cline Mines lie approximately five

        kilometres east of the Island Gold Mine. The exploration team

believe that there is potential for the Edwards' gold zones to trend

        across Richmont's property.



3.  21 Zone: Located less than 1 km northwest of the mine, historical drill

    results have been favourable and warrant follow-up drill testing during

    the current program.



4.  Alpha & X Zones of the Kremzar Mine area: High grade zones were drilled

proximal to the Kremzar mine but were not pursued as the mine was closed

    soon after. These zones, as well as with the deep extension of the

    Kremzar main zone, warrant drill testing due to the grades and the

    proximity to Richmont's current operations.



5.  ML-12-04 Zone: Located approximately two kilometres northeast of the

    mine, a shallow hole by Richmont in 2012 intersected 19.2 g/t Au over

    4.2 metres (not true width as the hole was at low angle with the

    structure) associated with a zone of strong shearing that warrants

    follow up drilling.



6.  22 Zone: Located 3 km northeast of the mine, a 4 km long geophysical

    anomaly has associated anomalous gold identified from limited historic

    drilling, trenching and grab samples.

Additional drill rigs will be mobilized to site and the program is expected to be completed before the end of 2015 or early 2016. It is not expected to materially change the Corporation's previously provided 2015 exploration budget guidance for Island Gold.

Island Gold Property

Richmont's Island Gold property covers 77 km2 which includes approximately 8 km of strike length of the favourable regional Goudreau shear system. The producing Island Gold Mine and its defined resources span roughly 1.5 km of strike length and over 1.0 km to depth along this prominent shear zone, where it is pervasively silicified with disseminated pyrite and significant high grade gold mineralization. On the Richmont property, this shear zone extends approximately 1 km to the west and 5 km to the east of the Island Gold Mine's current resources. Geologically, this shear acted as a major conduit for gold-bearing fluids which is further evidenced by this same shear hosting several past producing mines including the Magino Mine (114,000 Au ounces mined at a grade of 4.4 g/t Au from 1988-1992), the Edwards Mine (144,000 Au ounces mined at a grade of 11.0 g/t Au from 1996-2002) and the Cline Mine (63,000 Au ounces mined at a grade of 6.5 g/t Au from 1938-1942). Argonaut Gold's proposed Magino open-pit project containing 5.2 million of estimated resources grading 1.03 g/t Au, lies less than 2 km west of our Island Gold mine, on the north flank of the shear. The past producing Kremzar Mine (47,000 Au ounces mined at a grade of 4.8 g/t Au from 1988-1990) is approximately 1 km to the north of the main shear zone, along a cross cutting structure.
