Geological Interpretation by Larry Hulbert D.Sc.:
In detail, the magnetic fabric of the intrusive body is remarkably similar in size, shape and form to that of the Voisey’s Bay Complex in Labrador which hosts world-class Ni-Cu deposits, and was the last significant Ni-Cu discovery in North America (1994).
Magnetically, the mafic-ultramafic rocks underlying the Semple-Hulbert property stand out regionally as a striking magnetic anomaly. Based on the Geological Survey of Canada regional airborne magnetic surveys the intrusive rocks on this property are approximately twice as magnetic as any other known mafic-ultramafic body in the "Ring of Fire" (ROF) including the southeast portion of the ROF which hosts the recently discovered world-class Ni-Cu-PGE, Cr and Fe-Ti-V deposits. Detailed magnetic surveys conducted as part of a VTEM airborne geophysical survey over the Semple-Hulbert property enhanced the significance and understanding of this regional anomaly even further.
The detailed VTEM magnetic survey outlined a "spoon-shaped" intrusion. The East-West trending linear magnetic feature is analogous to the handle of the spoon and geologically is believed to represent a feeder-dyke. At its eastern end it flares out to a width of approximately 3 km and resembles the bowl portion of a spoon. This bowl shaped area represents the main mass of the magmatic chamber. The distinctive magnetic fabric within the main mass of the intrusion clearly defines an internal stratigraphy indicative of magmatic layering as is the case at Voisey’s Bay. When one examines the location of the electromagnetic conductors from the VTEM survey relative to the magnetically defined geology the Voisey’s Bay analogue and exploration model is most compelling.
