A 3D induced polarization (IP) and resistivity survey in conjunction with a high-resolution magnetic geophysical survey span the entire 4 km2 zone of advanced argillic alteration. This zone may represent a lithocap above a possible porphyry intrusive system (Figure 1).John Williamson, CEO commented, \"We have quickly and cost effectively advanced the Silver Pond porphyry target from a conceptual nature to demonstrating it has key characteristics of lithocaps found above porphyry systems. The 3D IP and magnetic geophysical surveys will be invaluable for interpreting the subsurface expression of this large alteration zone and outline potential mineralized domains and future drill targets\".The 4 km2 advanced argillic alteration zone at Silver Pond has never been drilled, mapped, or effectively explored and is only 850 m northwest of the low-sulphidation mineralization at Cliff Creek. SWIR (short-wave infrared) analysis of clay samples and soil and rock geochemistry show large-scale zonation patterns and metal associations indicative of high-sulphidation or porphyry mineralization (see May 26th news release). The 2020 exploration program at Silver Pond will include detailed geological mapping and expansion and infill sampling of 2019 soil, rock, and SWIR surveys. The high-resolution magnetic geophysical survey is expected to delineate fault zones as it has proven to be very effective at this at other zones on the Lawyers property. The 3D IP and resistivity survey will provide Benchmark the ability to view deep in the subsurface, below the lithocap alteration, where possible zones of high conductivity may be related to sulphide mineralization.Figure 1: Imagery showing the extensive clay alteration at Silver Pond and the spatial relationship to the Cliff Creek Zone (upper image).
