Tectonic Metals Inc. has announced that Phase II oriented diamond drilling commenced at the company’s Tibbs Gold Project after the previously announced deep-penetrating TITAN-160 (TITAN) ground-based geophysical survey (the survey) successfully identified interpreted low and high-angle controlling structures coinciding with gold-in-soil anomalies sharing the same geochemistry and host rocks as the mineralisation observed at Northern Star Resources’ nearby Pogo Gold Mine. These characteristics are key components of the ‘Pogo Geological Model’, which Tectonic applied to Tibbs resulting in numerous untested anomalies warranting drill testing.
Phase II drilling focuses on drill testing these Pogo-like targets, including West Trench, Johnson Saddle, Galosh, and Gray Lead West, which have never been drilled before. Oriented diamond drill holes will test for both low and high-angle structures as interpreted at these targets. At Pogo, both low and high-angle structural features acted as structural conduits for mineralisation, with faulting observed both at lithological contacts, which acted as weak zones amenable to faulting, and within single gneissic units. Both high and low-angle structures at Pogo are favourable hosts for gold-quartz vein mineralisation. Phase I diamond drilling is now complete with assays pending from the following Tibbs zones: Michigan, Gray Lead and Wolverine.
The survey was designed to determine the subsurface geological and structural architecture at Tibbs, specifically in the western extent of the project where multiple Pogo-like gold-in-soil anomalies are found in prospective gneissic host rocks. The survey successfully identified low and high-angle controlling structures coinciding with gold-in-soil anomalies, which the company interprets as high-angle feeder structures adjacent to low-angle lithological contacts and possible fault zones – an analogue to the structural controls on mineralisation observed at Pogo, located 35 km to the west of Tibbs. Four TITAN lines were completed for a total of 16.8 line-km surveyed across the property.
Tony Reda, President and CEO, commented: “Following the successful completion and interpretation of the results of Tectonic’s 2021 TITAN survey, we have kicked off our Phase II drill programme given the survey confirmed our exploration model of high-angle fault structures which host high-tenor gold, arsenic and bismuth soil anomalies that are found immediately adjacent to two panels of moderately dipping gneissic rocks. The gneissic rocks host gently dipping conductivity anomalies which may represent low-angle structures analogous to the shear structures which host the Liese veins at Pogo. Tectonic moved quickly to exploit the survey’s findings, commencing Phase II of our drill programme at our West Trench target, and we look forward to testing the never before drilled gneissic portion of Tibbs.”
