The AT4 gold occurrence lies 5.5km southwest of Eagle’s Nest (figure 1), on the interpreted south side of the Webequie shear zone (WSZ). The host sequence here is Victory Assemblage age (circa 2783Ma) mafic siltstones/mudstones, iron-formation, and intercalated basalts, gabbro and qtz-feld porphyritic rocks, similar to the stratigraphy noted above the Blackbird intrusion. Drilling in the area, originally targeting a string of EM conductors believed to be VMS related, intersected both narrow high-grade gold veins (e.g. 1.0m @ 9.9g/t Au) and wider low-grade zones. Gold mineralization at AT4 is typically associated with arsenopyrite bearing quartz-carbonate veins that cut sheared basalt, gabbro, and locally overprint oxide and sulfide-facies iron-formation. A highlight of gold intersections is shown in the table below.
Given the diversity and reactive nature of rock types in the area, coupled with proximity to the WSZ, the early indications of gold fertility at AT4 are very encouraging, and justify further follow-up exploration in this area.
