Richmont Mines Inc.: Updated Cripple Creek Drill Results Confirm Presence of Gold Mineralization; 3,500 Metre Winter Drilling Campaign Planned for 201108:30 EST Thursday, December 16, 2010MONTREAL, QUEBEC--(Marketwire - Dec. 16, 2010) - Richmont Mines Inc. (TSX:RIC)(NYSE Amex:RIC)("Richmont" or the "Company") is pleased to announce complete results from the second phase of its 2010 surface drilling campaign at its Cripple Creek property, located west of the Timmins Gold Camp in Ontario. Highlights:New results from Zone 16 include: 3.79 g/t Au over 16.35 metres, 4.55 g/t Au over 7.1 metres, 3.57 g/t Au over 5.6 metres, 26.34 g/t Au over 0.55 metres, and 15.81 g/t Au over 0.4 metres; Extensions of Zone 16 to the west and at depth reveal promising potential; An additional campaign of 3,500 metres planned for winter 2011. As detailed in the table below, the second phase of drilling yielded several interesting intercepts, including 3.79 g/t Au over 16.35 metres in hole CC-10-57. Notably, this result confirmed that the alteration zone containing the intercept of 73.53 g/t Au over 7 metres in hole CC-10-45 previously-released with results from the first phase of drilling (please see the release entitled "Richmont Mines Announces Start of a 3,500 Metre Drilling Campaign on Its Cripple Creek Property" published on June 10, 2010 for full details), broadens near surface.

DIS : Disseminated sulphides, VN : Veins, DIS+VN : Disseminated sulphides and veins While much exploration work remains to be done on this property, the Company obtained additional geological insight from the second phase of the 2010 drilling campaign, which encompassed 6 holes over 2,991 metres. Most importantly, drilling reaffirmed the gold potential of the sector, and also enabled for better understanding of the mineralization. Results from the campaign also confirmed the continuity of the main mineralized zone to a vertical depth of 650 metres and that the alteration pipe of Zone 16 extends at depth. Furthermore, drilling revealed that two types of mineralized zones are present. The first, containing disseminated pyrite, has a northern dip of approximately 65° and is found at the contact points of silicified mafic volcanics and ultramafic volcanics. The second system, formed by milky quartz veins containing iron carbonate and mineralized with gold, appears to be sub-horizontal, and cross-cuts other geological formations. Interpretation of this new information makes establishing true width of the mineralized gold zones difficult when they consist of the two types of mineralization.Richmont is planning to drill an additional 3,500 metres in the winter 2011. The goal of this upcoming exploration program is to confirm the new interpretation of Zone 16 provided by results obtained to date, to better target mineralized zones, and to test the extension of the Mahoney Zone at depth.
