Also, geochemical characterization of mine and waste rock is in progress by InterraLogic, Inc. and Enviroscientists, Inc. is directing environmental baseline studies and developing plans for the upcoming field season to lead to potential mine permit applications in early 2014.
Mr. Dircksen continued, "These studies will provide the basis for completion of our PEA by mid-year and, pending favorable results, more detailed investigations will follow in support of a Feasibility Study and submission of a Plan of Operations targeted for early 2014. We continue to advance the project toward production with confidence that it has considerable resource expansion opportunity and excellent potential to host a low cost, open pit, heap-leach gold operation."

Timberline's 2013 South Eureka drill program will prioritize expansion of the gold resource to the south of Lookout Mountain, including approximately 2,500 feet of strike extension toward South Adit in which assay data is currently of insufficient density to calculate resources. The Company also plans to drill test several targets at increased depth. In 2012, a hydrology hole beneath Lookout Mountain intercepted high-grade gold mineralization (0.138 opt (4.72 g/t gold) over the final 15 feet (4.6 meters)) down dip of the current resource, indicating considerable additional geologic potential at depth.
Timberline's district-scale South Eureka property is strategically located within the greater Eureka Mining District, just four miles from Barrick Gold's two-million ounce Archimedes / Ruby Hill mine. South Eureka features three distinct structural zones and includes past-producing open pits, along with several areas containing historic, non-compliant, gold resources and untested targets. These successfully drill-tested areas are combined and included in the summarized table below.
