InnovExplo Defines Next Phase of Exploration for Valentine Gold Lake Project

17 Targets Identified and $4 Million in Exploration Work Recommended

MONTREAL, QUEBEC and PORT WILLIAMS, NOVA SCOTIA--(CCNMatthews - Oct. 31, 2006) - Richmont Mines Inc. (TSX:RIC)(AMEX:RIC) ("Richmont Mines") and Mountain Lake Resources Inc. (TSX VENTURE:MOA) ("Mountain Lake") are pleased to report on the project compilation, target generation and exploration work proposal completed on the Valentine Lake Gold property by InnovExplo Inc. ("InnovExplo"), an independent mining and exploration consulting firm based in Val-d'Or, Quebec, Canada. The Valentine Lake property is located in central Newfoundland (Canada) approximately 55 km south of the town of Buchans.

The overall objective at Valentine Lake is to confirm and extend several gold mineralized zones: Valentine West; Leprechaun Pond; Osprey Pond; Victoria Bridge and Valentine East (Guano Pit). InnovExplo has concluded these main occurrences represent a significant gold potential and also illustrate targets for new discoveries at these locations. Geochemical sampling yielded anomalous gold values over the entire 27 kilometer structure. This area potential was demonstrated at Valentine East, situated at kilometer 12-13, where historical drilling has identified a 40 to 50 meter wide zone of mineralized trondhjemite. Historical assays include: 30.87 g/t gold over 1 meter and 5.55 g/t gold over 5 meters.

The essence of InnovExplo's conclusions are as follows:

1) The Leprechaun Pond gold deposit itself presents similar characteristics to Archean orogenic lodegold hosted in tonalite, granodiorite and trondhjemite and similar structural setting. Vein-style, geometry, distribution, mineralogy and alteration at Leprechaun Pond look similar at different levels to Archean quartz-tourmaline lode gold deposits from the Malartic - Val-d'Or area (Abitibi Subprovince), which currently host several gold mines.

2) InnovExplo's compilation of work to date on the property has led to the definition of 17 potential and favourable areas for gold mineralization. These areas have been described in detail with a work proposal and estimated budget for each of them. The work proposals have been ranked in four categories in order of importance, and their overall recommendations represent a total of $4,008,900 in exploration expenditures.

3) Recommendations for the next phase of exploration work include:

a) additional diamond drilling totaling 3,000 meters as a first phase;

b) a high-resolution helicopter-borne geophysical survey;

c) detailed geological mapping focusing on a structural study in order to establish a structural model for the Leprechaun Pond gold deposit;

d) whole-rock geochemistry and soil geochemical sampling along the 27 kilometer auriferous belt;

e) finally a scoping study which is strongly recommended for the property.

Richmont Mines has an option to acquire a 70% interest in the Valentine Lake property from Mountain Lake by carrying out $2.5 million in exploration work by October 31st, 2007. To date Richmont Mines has spent approximately $1.5 million dollars on the project and the exploration focus has mainly been on diamond drilling in the Leprechaun Pond area of the property.

"This independent report is shedding a new light on Valentine Lake and clearly demonstrates the unique exploration opportunity along strike from the known gold deposit," stated Allen Sheito, President and CEO of Mountain Lake.

Martin Rivard, President and CEO of Richmont Mines, "We are very encouraged by this report as it highlights the excellent potential of the Valentine Lake property."
