Several companies, including Dresser Industries, Echo Bay Mines, Freeport McMoRan and Tenneco Industries, conducted limited exploration programs in the vicinity of the present claim block, but left Gateway's Golden Dome exploration target essentially untested. BHP Minerals acquired a group of claims over the target area based on a stream sediment geochemical anomaly. BHP's efforts during its brief tenure were limited to geological mapping and interpretation.

Geology

The target area on the Golden Dome property is within a topographic basin that is covered by a veneer of glacial till. To the west of the basin, the lowermost units of the Upper Plate of the Roberts Mountain Thrust crop out on mountain ridges. This relationship suggests that the prospective Lower Plate stratigraphy should lie immediately east of these outcrops under the till-covered basin within the core of a plunging anticline. Several wide, altered structural zones project into the till-covered basin from the north. These structures contain highly anomalous Carlin-type indicator metals with arsenic values up to 4,000 ppm and antimony values up to 7,000 ppm. The target area lies at the projected intersection of these structural zones with the favourable Lower Plate carbonate rocks in the core of the anticline. Three holes were drilled in 2005 which intersected favourable stratigraphy. (see Current Exploration Program)

Current Exploration Program

Drilling programs carried out during the past three years have successfully encountered widespread anomalous gold mineralization in high angle fault structures that may represent leakage from a gold zone in the Lower Plate rocks at depth. The Company is planning further drilling to test these structures where they intersect Lower Plate rocks.
