Richmont Mines Inc.: New Deep Drill Results Reaffirm Promising Potential at Depth at Island Gold Mine

Marketwired

MONTREAL, QUEBEC--(Marketwire - Sept. 10, 2012) - Richmont Mines Inc. (RIC.TO)(RIC)(RIC), ("Richmont" or the "Corporation") is pleased to announce additional results from its 2011 and 2012 deep drilling program on its Island Gold Mine property (the "Property").

Highlights:

-- Drill results suggest that the C Zone is currently the most continuous

of the four zones (zones G, C, D and E1E) previously identified through

the deep drilling program, and that it appears to be a continuation at

depth of the zone currently being mined at Island Gold.

-- Once below a depth of approximately 500 metres, the C Zone is a steeply

dipping structure (sub-parallel) with similar geology to what is

currently being mined in the upper horizons of the Island Gold Mine

(quartz vein systems within an alteration zone).

-- New drill results in the C Zone include (all cut grades over true

widths): 31.60 g/t Au over 6.59 metres, 27.16 g/t Au over 10.62 metres

and 14.21 g/t Au over 8.02 metres. Previously-released drill results in

the C Zone include 27.26 g/t Au over 5.58 metres and 12.28 g/t Au over

7.24 metres.

-- Other results from the current drilling campaign include (all cut grades

over true widths): 11.14 g/t Au over 9.33 metres and 23.26 g/t Au over

2.0 metres, mineralized intercepts that have not yet been associated

with an identified zone.

-- 26,030 metres of deep exploration drilling have been completed in 2012

at the Island Gold Mine encompassing 30 holes and wedges. The 2012

surface and underground exploration drilling program will total

approximately 35,000 metres. There are currently 2 drill rigs active

from underground drill stations.

Paul Carmel, President and CEO, commented: "We are very pleased that our deep drilling program at the Island Gold Mine continues to deliver very promising results. In particular, our new drill results (please see Table 1 below) indicate that the C Zone is showing signs of becoming a well-defined mineralized zone that appears to be a continuation at depth of the zone currently being mined at Island Gold. When combined with our previous results, released in February of this year (please see Table 2 below), the new drill results in this zone provide further support for our confidence in the long-term potential at Island Gold to expand resources and increase mine life."

Gold Mine confirm potential at depth."

(3) High values are cut at 75 g/t.    

Mr. Carmel continued: "The objective of our deep drilling program at Island Gold is to establish resources below the current infrastructure of the mine, which currently reaches a maximum depth of approximately 400 metres below surface. Our aim is to tighten-up the drill spacing at depth in order to generate a preliminary resource in Q1, 2013. We continue to advance our 1,100 metre exploration drift from the -400 metre level of the mine to provide more effective access for drilling, while also evaluating the potential construction of an exploration shaft in order to accelerate the identification of deep resources at Island Gold."

The following table presents new drill results in the other zones (D, G, STH) that intersected a significant cut grade over a minimum true width of 2.0 metres. Mineralized intersections that have not yet been associated with an identified zone have been allocated to "X" Zone.

Additional details about the Island Gold Mine Property

The 84.4 km2 (8,444 hectare) Island Gold property is located 83 km northeast of Wawa, Ontario. Ore from the Island Gold Mine is processed at Richmont's on-site Kremzar Mill, an 850 tonne per day rated CIP mill. Since Island Gold began commercial production in October 2007, Richmont has produced more than 175,000 ounces of gold from this mine. Underground operations are accessed via a ramp, and the mine's infrastructure currently reaches a vertical depth of approximately 400 metres. As of June 30, 2012, the Island Gold Mine had a total of 185 employees.
