Timberline Resources Corp.: Timberline Identifies Large IP-Resistivity Anomaly at the Eureka Gold Project, Nevada COEUR D'ALENE, ID / ACCESSWIRE / February 3, 2021 / Timberline Resources Corporation (OTCQB:TLRS)(TSXV:TBR) ("Timberline" or the "Company") today announced results of an Induced Polarization - Resistivity (IP) geophysical survey (Figure 1) at its 100%-controlled Eureka Project in Nevada. The IP survey included 28.4 line-kilometres over eight lines, focused primarily at the Lookout Mountain Target. IP can be an effective tool for mapping subsurface electrical characteristics of the rocks related to the distribution of sulfide minerals and organic carbon, which are often associated with Carlin-type gold deposits. IP surveys may also help map fault structures that are related to or crosscut mineralization.
