VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/21/13 -- Goldstrike Resources Ltd. (TSX VENTURE: GSR)(PINKSHEETS: APRAF)(FRANKFURT: KCG1) is pleased to report the results of recent high resolution airborne and ground geophysics, geological mapping, structural interpretation, geochemical and alteration studies, petrographic studies, and spectral matching of remote sensing data on its 100% owned Plateau South property, where numerous high grade grab samples up to 15.45 ounces per ton have been documented at surface along the 25 kilometre Yellow Giant gold trend (News Release October 30, 2012). The detailed studies have clearly identified several excellent drill targets at large structural intersections that coincide with high grade gold seen on surface, and have also identified many other new areas with strong gold potential that remain to be explored.
The property's gold potential has been significantly enhanced by identifying and mapping the extent of several large areas of quartz-albite alteration up to 4.1 kilometres long and 2 kilometres wide that coincide with the high grade gold mineralization found at surface on both the VG and Goldbank zones. Magnetic maps and geological mapping show that the alteration and the highest gold grades are concentrated in areas where broad magnetic northeast-trending lows up to 1 kilometre wide cut across regionally deformed northwest-trending stratigraphy. All of the evidence to date is consistent with a new district scale gold-bearing system.

The recent high resolution airborne geophysical survey flown by Precision Geosurveys shows a series of broad northeast-southwest trending magnetic lows up to 1 km wide that cut across a newly mapped package of regionally deformed rhyolite volcanics. Geophysical and structural studies show that the volcanic rocks that have been folded twice about horizontal northwest-trending axes. The magnetic lows coincide with extensive areas where high grade gold has been found at surface, and are interpreted as zones of closely spaced fracture cleavage that have allowed large volumes of quartz and albite to invade and alter the volcanic rocks. A petrochemical study showed five times as much gold and ten times as much arsenic in sodium (albite) enriched zones relative to others, providing an additional vector for gold targets.
Three of the intersections where large northeast-trending magnetic structures cross the stratigraphy were subjects of reconnaissance prospecting and sampling late in the 2012 field season, and all three returned high grade gold values on surface, providing multiple strong drill targets. Company geologists believe the results to date indicate excellent potential for gold mineralization in the remaining unexplored structures and across the entire Yellow Giant System.
