Tectonic Metals Inc. has provided a summary of the company’s 2021 exploration activities and new project acquisition in Alaska, USA. Over the course of 2021, Tectonic successfully completed 5018 m of drilling, including 12 holes for 2319 m of the first oriented core diamond drilling and 18 holes for 2699 m of reverse circulation (RC) drilling at the company’s Tibbs Gold Project. Drilling tested known high-grade gold targets and newly discovered prospects exhibiting coincident gold-in-soil anomalies, high-grade mineralisation in grab samples, and both surficial structural lineaments and subsurface geophysical anomalies. Phase I drill results have been released; Phase II assays (85% of Tectonic’s total drill programme) are pending.
2021 highlights and key takeaways
- First-ever drill test of five targets possessing characteristics akin to the Pogo Geological Model.
- Since 2018, Tectonic has been diligently and methodically applying the Pogo Geological Model at Tibbs to generate drill targets in search of the next Pogo. In doing so, the company produced compelling drill-ready gold-in-soil anomalies that share the same host rock (gneissic) and similar geochemistry (Au-As-Bi) as well as interpreted high and low-angle structures observed in lineaments and Tectonic’s TITAN geophysical survey completed this summer.
- Gray Lead West drill target: situated immediately west of one of the only known high-angle structures carrying high-grade Pogo-style gold mineralisation outside of the Pogo mineral claims.
- Four holes (959 m), including 424 m of diamond core, which successfully intersected interpreted high and low-angle Pogo-style quartz veining; assays pending.
- First ever Pogo-style quartz veining intersected in the western, gneissic host rock region of Tibbs; assays pending.
- West Trench drill target: Tectonic rock grab samples returned Pogo-style quartz veining up to 190 g/t gold (Au), representing the second surface discovery of high-grade Pogo-like quartz veining in the highly prospective western gneissic region of the property. The 190 g/t Au rock grab sample coincides with a high-tenor gold-in-soil anomaly and geophysical anomaly.
- Five holes (952 m) drilled, first ever drill test; assays pending.
- Johnson Saddle drill target: two holes (586 m). Drill test of arcuate, high-tenor gold-in-soil anomaly, including a 790 ppb Au soil sample coinciding with low-angle structures observed in TITAN geophysics and lineament analysis: assays pending.
- Galosh drill target: two holes (357 m), first ever drill test of gold-in-soil anomaly coinciding with high and low-angle structures observed in TITAN geophysics; assays pending.
- TITAN-160 geophysical survey identified low and high-angle controlling structures coinciding with gold-in-soil anomalies warranting drill follow up in 2022.
- High-grade rock grab anomaly delineated and drill tested.
- Jorts drill target: Grab rock sampling returned gold values up to 50.3 g/t Au, with 11 rock samples grading greater than 20 g/t Au producing a 450 m long high-grade gold rock anomaly.
- Immediately followed up with Phase II drill test consisting of five holes (730 m); assays pending.
- Phase I oriented diamond drill results were announced from the Michigan and Gray Lead Zones earlier this year. The programme was successful in intersecting high-grade gold mineralisation such as 7.69 g/t Au over 6.12 m, including 33.92 g/t Au over 1.22 m and 12.45 g/t Au over 5.15 m, including 41.39 g/t Au over 1.26 m, and determining the structural orientation of the mineralisation at both the Michigan and Gray Lead Zones. Both zones are approximately 250 m in length and remain open along strike and at depth.
- Comprehensive mapping and sampling programmes were completed at Tibbs South, Mt. Harper, and Maple Leaf Projects.
- Acquisition of Flat Gold Project, a ~92 000-acre Intrusion-hosted, bulk tonnage opportunity in the Kuskokwim Mineral Belt with ~11 000 m of historical drilling with all mineralised zones remaining open at depth and along strike and numerous untested gold-bearing trenches, rocks samples and soils located 40 km from the Donlin Gold Project, jointly owned and operated by Barrick Gold Corp. and NOVAGOLD Resources Inc.
Tony Reda, President and CEO, commented: “Tectonic’s 2021 exploration programme at Tibbs was predicated on our desire to find the next mineable gold deposit in the Goodpaster Mining District. Our ambition is reflected in the capital we raised this year and the diligent, aggressive approach we have taken with this year’s exploration programme at Tibbs resulting in the deployment of two drills to site and the most targets being drill tested in one season at Tibbs. For us, the win is not only in discovering gold, but doing so in a safe and responsible manner. This year, like last year, we had zero COVID-19 cases. Were there challenges, yes of course, there always are, but how you deal with those challenges is what separates a good team from a great team. I am proud of our team, both in the field and off, for their ability to adapt to each situation, pivot, regroup and execute. The Phase I exploration programme was a success with drilling demonstrating high-grade gold at two Tibbs’ gold zones while prospecting, rock sampling and an accompanying geophysical survey fortified the merit of drill testing our gold-in-soil anomalies now. Having raised additional funds to allow us to be opportunistic, Tectonic quickly launched a Phase II exploration program and delivered a comprehensive drill test focused on making new discoveries in the gneissic terrain of our property. Lab delays mean the majority (85%) of our assays have yet to be released, but we eagerly anticipate sharing these with the market as soon as they are available.”
Eric Buitenhuis, VP Exploration, added: “2021 was a year of ‘firsts’ for the team at Tectonic, with a comprehensive exploration programme led by an aggressive drill campaign that stepped out on our previous discoveries, built on our existing knowledge and pushed into the previously unexplored western gneissic frontier at Tibbs. We not only drilled the first ever oriented diamond core at Tibbs but also completed comprehensive mapping and prospecting programs at our Tibbs South, Mt. Harper and Maple Leaf properties. Another first was our TITAN-160 survey, the first high-powered ground-based geophysical survey completed over the western rocks at Tibbs, which provided unprecedented insight into the nature of the controlling structures there. Our 2021 exploration programme reflected our attention to detail, aggressive targeting, and fundamental reliance on a scientific approach to advancing our projects.”
