Sterling Advances Lower Mine Development At The Sunshine Mine

 Wallace, Idaho -- May 29, 2007 -- (BUSINESS WIRE) -- Sterling Mining Company (OTCBB: SRLM) today announced that the Company's Sunshine Mine crews have completed excavation of a major underground electrical substation on the 3100 level of the Sunshine Mine. The substation which is designed to transform 13,200 volt power from the surface into 2400 and 480 volt power is essential to conduct mining activities on 3100 level and 2700 level.

"This is another key step in returning to production by the end of 2007," stated Mike McLean, the Mine Manager. "Not only will we have the required power for development and production activities on these levels, but we will have the power to support production from deeper levels."

Lower mine development was undertaken by Sterling's Sunshine Mine crew on 3100 level in mid-March while the Sterling Tunnel Project was nearing completion using contractor crews. The Sterling crew is now focusing on driving a ventilation drift to augment air circulation on 3100 level.

Atlas Fausett Contracting crews are expected to complete access from the Sterling Tunnel to unmined Sunshine vein projections and old Polaris Mine workings in mid-June. At that time, Sunshine miners will take over mining activities and begin drifting to evaluate mineral potential in the eastern portion of the historic Sunshine-Polaris Intervening Area. Mining in this area stopped in the early 1940's when the Chester Vein on 2700 level was discovered and a shortage of miners occurred due to World War II.

The Sunshine Mine now has 59 employees working to return the Mine to long-term sustainable production by year end.

Along with additional underground rehabilitation and restoration of site facilities, the timetable for the continuing work program anticipates production beginning in December 2007.
