One of these features is a 1.5 km long, roughly east-west trending magnetic high that is cut at three places by northeasterly, Type-16 oriented cross-fractures. Magnetic lows associated with these intersections are interesting since the injection of sulphides by gold-bearing fluids often converts magnetite, a magnetic oxide mineral, to pyrite, a non-magnetic sulphide mineral, resulting in patches of low magnetic intensity.
In the southern part of the survey area, another mafic unit is tentatively interpreted as a distal northwestern extension of the subvolcanically injected gabbro that hosts the Rice Lake and adjacent Cartwright deposits. Importantly, this southernmost mafic unit is also cut by the same regional Type-16 structures that are caused by the late stage deformation event that appears to have mineralized the entire central part of the Rice Lake greenstone belt.
