North Arrow Enters Option Agreement With Harry Winston For Lac De Gras Diamond Project

September 6, 2011

North Arrow Minerals Inc. ("North Arrow" or "the Company") (TSXV-NAR) is pleased to announce that the Company and Springbok Holdings Inc., ("Springbok") have signed an Option Agreement with Harry Winston Diamond Mines Ltd. and its wholly owned subsidiary, 6355137 Canada Inc. ("Harry Winston") in regards to their Lac de Gras property in the Northwest Territories. Harry Winston is a 40% owner of the adjoining Diavik diamond mine, which commenced production in 2003.

North Arrow's Lac de Gras property covers over 81,000 acres and is contiguous with property held by Harry Winston that covers nearly 226,000 acres. Under the terms of the agreement, the two properties collectively will form a "joint venture property". Harry Winston is to carry out exploration on North Arrow's property concurrently with their own, making expenditures of at least $5,000,000 over a five year period in order for the option to vest. Upon vesting, a joint venture will be formed in which Harry Winston will hold a 55% interest and North Arrow and Springbok will equally share a 45% interest in the entire 307,000 acre joint venture property.

The joint venture property forms a very large, contiguous block located within the prolific Lac de Gras diamondiferous kimberlite field in Canada's Northwest Territories, home to some of the richest diamond deposits in the world. The joint venture property directly adjoins the mineral leases that host the Diavik diamond mine, located only 10 km to the north and the Ekati diamond mine is located within 40 km to the northwest. The trend line defined by Diavik's mine project kimberlites runs directly through the centre of the joint venture property, while trend line defined by Ekati's mine project kimberlites crosses the western portion of the joint venture property..

Previous exploration has been carried out on portions of the joint venture property, but traditional surface till sampling for kimberlite mineral indicator trains has been hampered by thick glacial till cover. Work has already begun on mapping local ice directions and till characteristics in preparation for a systematic basal till sampling program, to be initiated in early 2012. The program will use a track mounted reverse circulation drill to sample a complete till column and reach basal till not accessed by previous sampling.

North Arrow CEO Gren Thomas commented, "We are pleased to enter into this Agreement with one of Canada's leading diamond producers and I look forward to once again working with Robert Gannicott and Dr. Chris Jennings, both of whom were integral to the Diavik mine discovery. North Arrow will benefit from having a major partner to advance the exploration on our property, while at the same time we will earn a significant interest in a larger property that has excellent prospects for the discovery of diamonds."

The Option Agreement is subject to customary conditions, including regulatory and Exchange approval.

The technical content of this news release has been reviewed and approved by Gordon Clarke, P.Geol (NT&NU), Vice President, Exploration for North Arrow and a qualified person under NI 43-101.
