March 18, 2015 VANCOUVER, Canada, March 18, 2015, Sonoro Metals Corp. (TSXV: SMO) (“Sonoro”) and Northern Empire Resources Corp. (“Northern Empire”) today announced the acquisition through staking of 23,880 acres (9,664 hectares) to expand the Hilltop Gold Project (“Hilltop”) located 90 km southeast of Fairbanks, Alaska, USA. Pursuant to an option agreement announced on March 11, 2015, the two companies have expanded the size of Hilltop, from 7,840 acres (3,172 hectares) to an aggregate 31,720 acres (12,836 hectares), through claim staking. The new claim block is comprised of 147 – 160 acre State of Alaska claims and 9 – 40 acre State of Alaska claims. The Hilltop block is now contiguous with Northern Empire’s Richardson Property to the east. John Robins, Northern Empire’s Chairman stated. “We have effectively quadrupled the size of our land position because of an opportunity identified by our technical team. Hilltop now covers a significant geophysical magnetic and resistivity anomaly generated by a State of Alaska Division of Geological and Geophysical Survey airborne survey completed in 1994 and also consolidates claims covering prospective structural extensions.” Kenneth MacLeod, President & CEO of Sonoro, added, “Through the engagement of Northern Empire as the operator of the Hilltop project, we have been able to expeditiously capitalize on the extensive regional knowledge of the Northern Empire technical team to secure the compelling exploration targets surrounding the original Hilltop property.” 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 90 km southeast of Fairbanks, Alaska and 70 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 31,720 acre (12,836 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.

Hilltop Option Agreement The Letter of Intent between Sonoro and Northern Empire as announced March 11, 2015, is subject to receipt of all necessary regulatory approvals, including the acceptance of the TSX Venture Exchange. To exercise the option and earn its 60% interest in the Hilltop block, Sonoro must spend C$3,000,000 on exploration activities to advance the Hilltop block and issue 1,000,000 Sonoro shares to Northern Empire prior to December 31, 2019.
