The Margaret Lake Property covers a portion of the southeastern Slave Geological Province, an Archean terrane ranging in age from 4.03 Ga to 2.55 Ga (Bleeker et al., 1999). The area consists of predominantly granitic to granodioritic intrusions, high-grade gneisses and migmatites, along with primarily sedimentary supracrustal rocks to the east.
The emplacement of kimberlite bodies in the area is believed to have occurred approximately 542 Ma during the Cambrian Period. 87Rb-87Sr geochronology indicates that the age of the 5034 pipe is 542.2 ± 2.6 Ma (Heaman et al., 2003). Erosional processes since emplacement have had the significant effect of stripping the kimberlites down to their root zones, preserving only the hypabyssal and diatreme facies.
Spring 2018 Drill Program
The Company is currently conducting a diamond drilling program that will test six (6) kimberlite targets at Margaret Lake (see press release dated May 18, 2018). Each of the targets displays a gravity low, bedrock conductor, or combination of both, and have been interpreted as having geophysical characteristics potentially representing kimberlite bodies.
The Company’s exploration model is based on similar methods previously utilized by Kennady Diamonds to delineate kimberlite targets. Kennady noted correlations between targeting non-magnetic pyroclastic kimberlite targets located next to a magnetic kimberlite dyke, with electromagnetic (EM) and gravity responses. This exploration model ultimately led to the delineation of the Kelvin-Faraday resource located contiguous to the south and east of the Margaret Lake property.
