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.

Both of these strong magnetic zones are located in topographic valleys that have not been well prospected due to a lack of outcrops in these areas. This is evident when the magnetic data is overlain on high resolution LiDar topographic data......Traps7
