Tectonic Metals Inc. Identifies Robust High-Grade Gold Anomaly and Mobilizes Second Drill to Tibbs Gold Project

• Grab rock sampling at the Tibbs Gold Project's ("Tibbs") Jorts target returned gold values up to 50.3 g/t Au, with 11 rock samples grading greater than 20 g/t Au producing a 450m long high-grade gold anomaly.
• Mineralization is similar to localized high-grade gold-bismuth-tungsten mineralization at Kinross Gold's Fort Knox gold mine near Fairbanks.
• High-grade grab rock samples appear to be controlled by a prominent northeast-trending structural zone which hosts Northern Star Resources' neighboring Brink Gold Zone, 3.7km to the southwest.
• Tectonic has mobilized a second drill to site for immediate follow up with 1,200m of RC drilling planned in Jorts target area.
• Additional 2,500m of RC drilling planned for other high priority targets at Tibbs. Drilling extended to October 2021.

VANCOUVER, Sept. 7, 2021 - Tectonic Metals Inc. (TSXV: TECT) (OTCQB: TETOF) (FSE: T15B) (the "Company" or "Tectonic") today announced initial results from the Company's 2021 mapping campaign at Tibbs, located less than 35 kilometers ("km") from Northern Star Resources' (ASX: NST) Pogo Gold Mine ("Pogo"). Grab rock sampling in the southern extent of Tibbs produced two robust, high-grade gold rock anomalies with gold values ranging from trace to 50.3 g/t Au at the Jorts Prospect ("Jorts") and trace to 7.8 g/t Au at the Jeans Ridge Prospect ("Jeans"), 1.25km to the northeast of Jorts. Mineralization at both prospects consists of granodiorite-hosted sheeted quartz veins which contain bismuthinite and rare visible gold ("VG"). Mineralization is interpreted to represent veining associated with an intrusion-related gold system and strongly resembles the high-grade component of mineralization at Kinross Gold's (TSX: K) Fort Knox gold mine.

Tectonic is also pleased to announce that a second drill rig (Reverse Circulation ("RC")) has been mobilized to Tibbs to scale up the Company's exploration program by focusing on two priority objectives:

1. Immediately drill test the Jorts and Jeans targets with approximately 1,200m of RC drilling.
2. Test Pogo-like low-angle structures interpreted from the recently completed TITAN-160 geophysical survey and observed in drill core from the Company's ongoing diamond drilling campaign with a further ~2500m of RC drilling in the western portion of Tibbs.

Details of the TITAN geophysical survey and Tectonic's interpretations can be found here.

Based on the exciting new sampling results at Tibbs, Tectonic has elected to defer the drilling of the Company's Seventymile Gold Project ("Seventymile") until next season to focus its time, energy and capital on these newly identified, high-grade gold targets at Tibbs. Up to 3,700m of additional RC drilling is planned for Tibbs with work expected to continue into October 2021.

Tony Reda, President and CEO, commented, "We are extremely excited by the results of our early-season mapping and sampling program at Tibbs, which exceeded our expectations with 11 of 44 rock samples from Jorts returning over 20 g/t gold, including two samples returning over 50 g/t gold. These high-grade samples are found within a prominent northeast trend of mineralization beginning 3.7 km to the southwest at Northern Star Resources' Brink prospect and running through Tectonic's ground at Jorts and Jeans. With the mobilization of an RC rig to site, Tectonic is drill testing these new anomalies now, along with the newly identified low-angle structures observed in our Phase I diamond drilling, acting decisively and aggressively to advance our exploration targets."

New Drill Targets - Tibbs South
In early summer, a four-week mapping and prospecting campaign was completed in the underexplored southwest corner of Tibbs situated on Native-owned land leased from Doyon, Limited ("Doyon"), one of Alaska's largest Native Regional Corporations (see Tectonic news release here). Exploration this season focused on both the Jorts and Jeans targets, which are separated by 1.3 km and are situated adjacent to claims owned by Northern Star Resources. Both Jorts and Jeans are located on the same northeastern trend that hosts Northern Star's Brink Gold Zone ("Brink") and the adjacent Porthos Ridge exploration target, immediately west of Jeans.

A total of 223 grab rock samples were collected during the mapping campaign, with 44 collected at Jorts and 27 at Jeans. Samples from the Jorts prospect returned gold values from trace to 50.3 g/t Au, with 35 of 44 rock samples returning gold greater than 0.200 g/t Au, 16 samples returning greater than 10 g/t Au, including 11 samples over 20 g/t Au. Mineralization at Jorts is found within a core trend spanning 450m northeast-southwest along the nose of a ridge and talus slope. The source of the anomalism appears to be a northeast-trending bench or structure, and the entirety of the anomaly is found within chloritized and quartz veined granodiorite. Samples from the Jeans prospect returned gold values from trace to 7.86 g/t Au, with 9 of 27 samples returning greater than 0.200 g/t Au. Jeans consists of a flat-topped west-trending ridge approximately 200m wide, with mineralization observed in felsenmeer along the ridge for 200m in a northwest linear orientation. Quartz veining is found within granodiorite immediately adjacent to a northwest-trending contact with a diorite body.

Qualified Person & QA/QC
Tectonic's disclosure of a technical or scientific nature in this press release has been reviewed, verified and approved by Eric Buitenhuis, M.Sc., P.Geo., Tectonic's Vice President Exploration, who serves as a Qualified Person under the definition of National Instrument 43-101.

The analytical work for the 2021 rock sampling program was performed by Bureau Veritas Laboratories ("BV"), an internationally recognized and accredited analytical services provider, which is independent of Tectonic. All rock samples were prepared using procedure PRP70-250 (crush, split, and pulverize 250g to 200 mesh) at BV's Fairbanks, Alaska facility. Samples were then sent to Hermosillo, Mexico, where they underwent analysis for gold by method FA430 (30-gram Fire Assay fusion with an atomic absorption finish (AAS). Samples returning >10 g/t Au were re-analyzed using method FA530-Au (30g Fire Assay with gravimetric finish). Additionally, a 0.25g pulp was sent to the Vancouver, British Columbia lab for a four acid Inductively Coupled Plasma Emission Spectrometer (ICP-ES) analysis for 35 elements using method MA300. Quality Assurance and Quality Control procedures include the systematic insertion of blanks and standards into the sample string at a rate of approximately 1/10 (10%). Samples are placed in sealed and security tagged bags and shipped directly to the BV preparation facility in Fairbanks, Alaska.
