March 11, 2015 ANCOUVER, Canada, March 11, 2015, Sonoro Metals Corp. (TSXV: SMO) (“Sonoro”) today announced the signing of a letter of intent (“LOI”) with Northern Empire Resources Corp. (“Northern Empire”), pursuant to which Sonoro will enter into an option agreement to acquire a 60% interest in Northern Empire’s 7,840 acre Hilltop Gold project (“Hilltop”) located 115 km south of Fairbanks, Alaska, USA. To exercise the option and earn its 60% interest in the Hilltop project, Sonoro must expend C$3,000,000 on exploration activities to advance the Hilltop project and issue 1,000,000 Sonoro shares to Northern Empire, prior to December 31, 2019. During the term of the option, Northern Empire will be the operator of the project. In a joint statement, John Robins, Chairman of Northern Empire and Kenneth MacLeod, President & CEO of Sonoro, concluded that, “The Hilltop project is a very compelling gold project located in the Tintina Gold Belt, one of North America’s most prolific gold regions.” MacLeod further added that, “The management team at Sonoro is especially pleased to be able to participate in the exploration of this strategically-located property and to draw upon the extensive technical expertise of the principals of Northern Empire as we advance the Hilltop project.” About the Hilltop Gold Project Northern Empire holds a 100% interest in the block of claims forming the Hilltop project within the broader Richardson Gold District (excluding placer gold). Hilltop is an exploration stage gold project located 115 km southeast of Fairbanks, Alaska and 40 km northwest of Delta Junction in east-central interior Alaska. Hilltop is located approximately 75 km from Sumitomo’s Pogo mine (4.973 million ounces at 12.5 g/t gold; http://www.sumitomocorp.co.jp/files/topics/25649_ext_31_en_0.pdf) and 135 km south of Kinross’s Fort Knox mine (3.8 million ounces at 0.45 g/t Au; http://www.kinross.com/operations/operation-fort-knox-alaska-usa.aspx). The 7,840 acre (3,172 hectare) Hilltop property is bordered on the south by the all-weather and paved Richardson Highway. In addition, Hilltop is proximal to both a high power electrical transmission line and the Trans-Alaska Pipeline. Access into the interior of the property from the Richardson Highway is via a new system of logging roads and trails which makes most points within the Hilltop project area accessible for exploration activities.
