Midland begins helicopter-borne gold survey

The major Detour Lake ore deposit hosts an aggregate 16.45 million ounces of gold in measured and indicated resources
based on a cut-off grade of 0.5 g/t Au, including 14.86 million ounces of gold in near-surface mineral reserves, and commercial production is expected to begin in early 2013 (Source: NI 43-101 report by BBA for Detour Gold dated March 15, 2011).

The new VTEM survey, totalling about 400 line kilometres, is mainly designed to detect new gold- bearing mineralized zones across this extensive property which has seen very little exploration to date. This type of survey is known for its exceptional depth penetration and provides a more accurate definition of targets than conventional systems. Recent successes obtained with this type of survey on Midland's Laflamme Property, in partnership with North American Palladium Limited, further confirm the powerful effectiveness of this system, able to detect anomalies and mineralized zones that remained undetected by other means, in areas with thick overburden (see press release dated June 15, 2011). At Detour Lake, discovery of the main zone (Detour Anomaly 38) is directly attributed to the presence of an airborne electromagnetic anomaly detected during an Input survey in 1974.

Last March, Midland completed a helicopter-borne magnetic survey totalling 1,300 line kilometres, to clarify the geological and structural framework of the Casault Property. A detailed structural interpretation based on this magnetic survey identified several new
exploration targets characterized by structural complexities, many of which are located along the western extension of a structure previously drill-tested by Queenston, who reported historical drill results up to 4.3 g/t Au over 12.2 metres (Source: MRNF SIGEOM NTS sheets 32E14 and 32E15). The new structural interpretation also resulted in the identification of an ENE-trending structure
located less than 5 kilometres along the western extension of gold-bearing zones drilled by Balmoral Resources Ltd on its Martiniere property. These drill holes intersected 2.4 g/t Au over 72.0 metres, including a high-grade interval at 11.18 g/t Au over 12.0 metres (Source: Balmoral Resources Ltd press release dated March 2, 2011).

The Casault Property is located about 140 kilometres north of the town of La Sarre in Quebec. It now consists of 280 wholly-owned claims for a total surface area of about 156 square kilometres. The property covers a strategic land position of more than 25 kilometres strike length along the major Sunday Lake Deformation Zone, known for its very strong potential to host significant gold
deposits.
