Pacific Ridge Survey Finds Positive Residual Anomalies at TL Zinc Project

Pacific Ridge Exploration Ltd. ("Pacific Ridge" or the "Company") reports that it has received the results from a gravity survey over its TL Zinc Project. All three lines surveyed revealed positive residual anomalies in the range of 0.5 to over 1 milligal that show a good correlation with an underlying conductor as defined by the Fugro HELITEM survey flown over the property in 2012. The target at TL is a large Broken Hill type or SEDEX (Sedimentary Exhalative) Zn-Pb-Ag massive sulfide deposit.

Gerry Carlson, President of Pacific Ridge stated: "We are very pleased to note the spatial correspondence between the gravity anomalies and the electrical conductor. These mutually supportive geophysical signatures, in combination with favourable geology and strategically located surface showings, provide an increased measure of confidence that a significant metallic sulphide body occurs at depths of 300 m or less." A compilation map showing the gravity results relative to the HELITEM conductor can be viewed at under Projects/TL Zinc.

The gravity survey and initial processing of the data was carried out by SJ Geophysics Ltd. of Delta, BC. Further processing of the gravity data was completed for the Company by Dr. Fred Cook of Salt Spring Imaging, Ltd.

About the TL Property

TL is a 6,420 hectare, road accessible zinc-lead-silver project located 80 km northeast of Vernon, British Columbia. The airborne magnetic-electromagnetic HELITEM survey defined a strong conductive layer, 4 km in length and approximately 100 to over 200 m wide that appears to be conformable within the flat-lying stratigraphy and could reflect massive sulphide mineralization. Mineralized float and outcrop samples comprise massive to semi-massive sulphide, containing sphalerite, pyrite and pyrrhotite. Of 56 grab samples collected, 40 assayed +1% Zn with a range of 1.08% to 18.87% and an average of 4.96% Zn.

Trenching, outside the main target area, encountered a zone of 7.16% Zn over 4 m. Drilling below the trenches (6 shallow holes, 490 m) encountered a 10 to 13 m thick sulphide mineralized zone with zinc values ranging from less than 1% to 5%. Mineralization in trenches and drilling is believed to be a peripheral mineralized horizon stratigraphically above or distal to the main exploration target. The property is ideally situated with nearby highways, electrical power grid and rail.

Proposed Program

The Company has made application for its drill permit and, once received, is planning for a 2,000 m drill test of the TL Zinc target.
