The Maroon Cliffs target is located on the northern nose of the McTagg anticlinorium, and is defined by an Eskay Creek-like magnetic anomaly comprised of magnetic highs surrounded by a ring of magnetic lows (Figure 18). In addition to the Eskay Creek-like magnetic bullseye pattern, the Maroon Cliffs target is associated with deep-seated 3D magnetic susceptibility protuberances like those seen at Eskay Creek (Figure 19). Legacy soil sampling data for the western portion of Maroon Cliffs shows Ag and Hg anomalies. These pathfinder elements are associated with Au mineralization at Eskay Creek and the numerous VMS showings on Eskay’s Property. A refined BLEG (Figure 20) survey conducted in 2022 shows a strong Au anomaly immediately downstream from the Maroon Cliffs target. All of this data combines to make Maroon Cliffs a compelling target for exploration in 2023.
Figure 18: Soil sample Ag assay results covering the western end of the Maroon Cliffs magnetic anomaly. Elevated concentrations of the Au-pathfinder element Ag coincide with the western portion of the magnetic anomaly. Exploration of this target in 2023 will include extensive geological investigations of this magnetic anomaly, followed by drilling.

The Eskay Creek VMS deposit is associated with a deep-seated zone of elevated magnetic susceptibility that is coincident with a bulls-eye style magnetic anomaly shown by the magnetic tilt derivative data shown in Figure 18. The Maroon Cliffs target is defined by a similar, but larger magnetic anomaly. Soil sampling and BLEG data in the western part of the Maroon Cliffs area support the Au and Ag prospectivity of this geophysical target.
Figure 20: A map showing the Au results for the 2022 BLEG program that utilized the LiDAR data collected in 2021 to draw refined catchment basins. Two very strong BLEG anomalies are located immediately downstream from the Maroon Cliffs magnetic anomaly. This combined with the promising soil results reported above make this a highly prospective target for the 2023 exploration program.
