In advance of a Nov. 4 shareholder vote to merge with West Timmins Mining Inc., Lake Shore Gold Corp. has updated its NI 43-101 report.
Mineral reserves are said to be 3.4 million tonnes at a grade of 7.5 grams per tonne, though this updated reserve was created using historic drilling without including any exploration progress since 2007.
The new report also assumes a 7.5-year mine life with production capacity of 1,500 tonnes per day.
The mine's peak annual production of 120,000 ounces is based on an eventual cash operating cost of US$322 per ounce.
Commercial production at the site is being targeted for the fourth quarter of 2010.
