Gold Coast Mining Corp. announced significant progress in its goal to develop its Skull Valley, Arizona claims along with its joint venture partner, Western Sierra Mining Corp. Since completing its previously announced milestones (initial surveying, staking and preparation for sampling), the joint venture has taken several steps forward in its plans to develop the Gold Crown and GS 1-4 properties. After the initial surveys, research and sampling programs Western Sierra has decided to narrow its focus for the larger sampling program to a specific area of 316.45 acres of the initial claims. It is the belief of both companies that this area is of higher significance regarding mineralization and therefore this is where resources should be concentrated to maximize results. Marking and flagging of additional sampling sites within this area has been completed with crews being scheduled to take samples for further processing. Additionally, the joint venture announced that Western has received approval for the Mineral Exploration Permit which allows for further sampling and exploration of the claims. Approval has also been received from the State of Arizona for the company's Plan of Operation and the joint venture has refilled the state leases for the year 2012-2013.
