Abcourt Provides Sleeping Giant Project Development Update

Abcourt Mines Inc. (" Abcourt " or the " Corporation ") (TSX Venture: ABI) (OTCQB: ABMBF) is pleased to provide an update on the ramp-up activities at the Sleeping Giant Project in Eeyou Istchee, Québec.

Pascal Hamelin, President and CEO of Abcourt, commented: "We are progressing very well with the project by now having the mill circuit with a full inventory. We are now increasing the gold inventory in the mill circuit. The next phase in the development of the project will be to start delivering gold bars to the market in a high gold priced environment. In the coming months, the plan is to ramp up operating the mill 40 hours per week at a rate of 30 tonnes per hour. Once we reach that level, we will increase production to 80 hours per week at the same rate of 30 tonnes per hour. Last week, we also reached an important milestone by commissioning our sleep camp. We will be able to attract more talents on our team to reach the goal of eventually produce 30,000 ounces annually."
