Tectonic Metals Acquires Flat Gold Project - Intrusion-hosted Gold System 40km North of Donlin Gold Project in Alaska

VANCOUVER, Sept. 28, 2021 - Tectonic Metals Inc. (TECT: TSXV) (TETOF: OTCQB) (T15B: FSE) (the "Company" or "Tectonic") today announced the acquisition of the Flat Gold Project ("Flat"), an intrusion-hosted, bulk tonnage gold project located in southwestern Alaska, just 40km north of the Donlin Gold Project ("Donlin"), which is currently being advanced jointly by Barrick Gold Corporation (GOLD: NYSE; ABX: TSX) and NovaGold Resources Inc. (NG: TSX; NG: NYSE American). Flat consists of 92,160 acres of Native-owned land belonging to Doyon, Limited ("Doyon"), one of Alaska's largest Native Regional Corporations and private landholders. Doyon and Tectonic have formed a mutually beneficial mineral lease property agreement covering all aspects of exploration through to production, including royalties and ESG provisions. The resulting agreement aligns the interests and expectations of both parties involved, reduces risk, and creates a process that is capable of advancing a project from discovery through development and production to final reclamation.

Tectonic's President and CEO, Tony Reda, commented, "The acquisition of Flat provides Tectonic with access to one of the most exciting gold exploration opportunities in Alaska. The property's location, just 40km north of Donlin, is enhanced by gold mineralization consistent with that found at the Kinross Gold's Fort Knox mine and Victoria Gold's Eagle mine. Flat also has the potential for free-milling gold, implying a simpler, less energy-intensive extraction process upon mining. This, in combination with historically mined placer gold deposits in creeks draining the property, points to an opportunity with a low-cost path forward. Tectonic is proud to once again be partnering with our largest shareholder, Doyon, to unlock the exploration potential at Flat. We look forward to focusing our methodical, innovative and targeted approach to gold exploration on the over 90,000-acre district-scale opportunity at Flat for the benefit of all Tectonic's shareholders and stakeholders."

Flat is located in the Kuskokwim Mineral Belt 40km north of the giant Donlin Gold Project and hosts intrusive-hosted, sheeted quartz vein gold mineralization similar to that found at the Fort Knox (Alaska) and Eagle (Yukon) gold mines owned and operated by Kinross Gold Corporation (K: TSX; KGC: NYSE) and Victoria Gold Corporation (VGCX: TSX) respectively. Since 1908, when gold was first discovered at Flat, the immediate vicinity has been notable as an area of significant placer gold mining activity with an estimated 1.4 million ounces of placer gold produced from streams draining the Chicken Mountain - Black Creek complex¹. Historic exploration work has delineated a nearly 4km long gold-in-soil anomaly formed by intrusion-hosted mineralization that begins at surface and remains open along strike and at depth.

The Opportunity
Flat represents a rare opportunity: a large scale, intrusion-hosted gold system with mineralization beginning at surface in close proximity to a world-class gold deposit, within the 4^th largest placer mining district in Alaska. Historical exploration work has demonstrated continuity of low-grade gold mineralization (~1 g/t Au), but also potential for discrete high-grade mineralization (>20 g/t Au), as observed in similar geological settings such as the Fort Knox gold mine. Indications are that gold in the project area is, at least in part, free milling, which suggests a simpler, more cost-effective and less energy intensive method for gold recovery upon mining. Tectonic plans to conduct data compilation prior to a preliminary metallurgical test work program utilizing existing drill core.

Detailed maps and historic drill data relating to Flat may be found on Tectonic's website here.

Flat Highlights

• Flat is located 40km north of Donlin in the Kuskokwim Mountains on 92,160 acres of Native-owned land belonging to Doyon
• Flat is accessible by air and benefits from existing on-site infrastructure including a 4100-foot-long gravel airstrip, extensive access roads and trails from historic placer mining, winter trail access and proximity to the Kuskokwim River, which is navigable by barge 6 months of the year.
• The project consists of two main target areas, Chicken Mountain and Black Creek/Golden Horn.
• • Chicken Mountain: Gold at Chicken Mountain occurs as disseminated and fracture-controlled mineralization within a late-stage quartz monzonite intrusion, which appears to have been the major source of placer gold in the Flat district. This target comprises an open ended +100 ppb gold-in-soil anomaly extending 3,800m x 600m in a north-northwest orientation over the core of exposed intrusion. Gold is hosted within quartz veins which contain free gold, arsenopyrite, pyrite, stibnite, cinnabar, and rare chalcopyrite. Historic drilling intersected bulk-tonnage gold mineralization, although thinner, high-grade intervals are observed.
  • Black Creek/Golden Horn: Mineralization is contained within northeast striking steeply dipping, intrusion-hosted sheeted sub parallel veins. Narrow veins contain quartz and limonite while wider veins (to 18 inches) contain open space fills of massive stibnite with pyrite, arsenopyrite, cinnabar, scheelite and native gold. Contact related vein and disseminated bulk tonnage mineralization is hosted within sedimentary and volcanic rocks. Most notable is the Golden Hornfels ("Golden Horn") zone which occurs along the eastern contact of the Black Creek stock.
• Consistent gold mineralization in intrusive-hosted, sheeted quartz veins at Flat are structurally similar to that found at the Fort Knox and Eagle Gold Mines owned by Kinross and Victoria Gold respectively.
• The Flat area represents one of Alaska's best examples of a direct, preserved bedrock source of mineralization for surrounding placer deposits. Placer gold is found within all the creeks that drain the Chicken Mountain - Black Creek complex, with the Flat area producing over 1.4 Moz of placer Au throughout a protracted history of placer mining.
• Historical hard rock exploration at Flat occurred sporadically from the 1960's to 2003 and consisted of surficial geochemical sampling, geophysics, and both reverse circulation ("RC") and diamond drilling. Approximately 11,000m of RC and diamond drilling has been conducted on the property. Flat remains fully open for expansion. Multiple near-surface targets remain untested, and potential exists for blind and buried mineralization as well as possible high-grade vein mineralization.
