During the winter of 2019, an airborne high-resolution magnetic survey in the Itchen Lake and Point Lake area was flown for the Northwest Territories Geological Survey (NTGS) by EON Geoscience Inc. The survey area is located in the Slave craton, covering a block of ground on NTS 086H, 086A, and 076E.

The goal of this geophysical interpretation of aeromagnetic data is to define and map structures that are potentially prospective for the mineralization and identify targets for future work. The interpretation is based on a multi-dataset stacking technique in which the expression of features was compared across various data layers, and features were manually traced on a series of colour-stretched and shaded-relief grids. Several linear or curvilinear features have been interpreted as dykes, faults, and lineaments. Three hundred and fifty-nine of the best potential kimberlite targets were selected and out of them eighty-two are the high priority. The selection process involved correlation of anomalies defined by the Keating Correlation Coefficients and Euler Deconvolution techniques. 3D inversion was also performed to enhance the structural behavior of the geology. This geophysical interpretation will be published as an NTGS Open File.
