Review of works by previous operators, as well as data from the current program, indicates that the Mad Kiss mineralization is controlled by what appears to be an isoclinal anticline with the axis plunging at 70 degrees and trending approximately 280 degrees (meridian).
Structural analysis will determine the exact nature of the geology, though it is possible that the mineralisation outline defines an overturned isoclinal synform with both limbs truncated by erosion below shallow surface cover.
Benedict (1945) recognized major isoclinal overturned folds where previous interpretations had indicated a single, very thick, inclined sequence.
Evidence for at least locally intense deformation (tight to isoclinal folds) was observed in siltstone and shale of the Goose Harbour Lake and Lincolnville members.
Since the Bonanza Ledge is interpreted as a replacement body that is replacing the fold noses of tight isoclinal folds that in the Bonanza Ledge area are flat lying rod shaped bodies, it is believed that these intersections represent true thickness or as close as true thickness can be estimated in this style of mineralization.
A single traverse of eight drill holes at Murphy South, combined with Stage I drilling and geophysical inversion modelling, suggests that a large body of magnetite gneiss occurs in this area as a large overturned isoclinal fold, with a south southeast dipping axial plane.
