ROSCAN ANNOUNCES OPTION ON THE GOLDEN MILE PROPERTY IN NEVADA

Toronto, Ontario – July 15, 2010 – Roscan Minerals Corporation (“Roscan”) (TSXV:ROS) is pleased to announce that it has signed an option agreement (the “Agreement”) with Portage Minerals Inc. (“Portage”) to acquire Portage’s option to earn a 70% interest in 5 patented and 19 unpatented mineral leases in Mineral County, Nevada (the “Golden Mile Property”).

In order for Roscan to exercise its option pursuant to the Agreement, it must (i) pay US$20,000 to Portage; (ii) issue 100,000 common shares of Roscan to Portage prior to December 31, 2010; (iii) make all expenditures required (US$300,000) to be made on the Golden Mile Property on or before December 31, 2010; and (iv) pay all fees or costs assessed by the Bureau of Land Management with regard to the Golden Mile Property from and after August 31, 2010. Upon earning its interest in the Agreement, Roscan must incur a total of US$2,500,000 in exploration expenditures on the Golden Mile Property before December 31, 2013 and issue a further 300,000 common shares of Roscan to Columbus Gold (US) Corp., in order to earn its initial 60% interest in the Golden Mile Property. Roscan may earn an additional 10% interest (for a total of 70%) by completing a positive feasibility study on the Golden Mile Property.

Portage was granted the option to earn a 70% interest in the Golden Mile Property pursuant to an option agreement (“Option Agreement”) between Portage and Columbus Gold. Roscan will assume all of the rights and responsibilities assigned to Portage under the Option Agreement. The Agreement is subject to regulatory approval and acceptance by Columbus Gold.

The Golden Mile Property consists of 24 mineral claims which are, in part, subject to underlying annual lease payments and net smelter return royalties. The claims cover approximately 154 hectares (380 acres), along the Walker Lane Gold Trend in Southwest Nevada. During the 1930’s the property produced approximately ten thousand tonnes of ore grading 12 g/t (0.42 oz/t) gold. Geophysical surveys and drilling carried out in the 1970's, 1980's and by Columbus Gold in 2006, defined skarn, breccia and disseminated gold mineralization. The drilling includes several high grade gold intercepts, including one intercept of 16 g/t (0.56 oz/t) gold along 29.5 m (96.8 ft), which occur within a broad area of lower grade gold mineralization. The historic data was compiled pre National Instrument 43- 101 reporting.

Roscan is a junior exploration company listed on the TSX Venture Exchange under the symbol ROS.V. Roscan currently has 26,699,575 common shares issued and outstanding and has working capital of approximately CDN$475,000.
