TECTONIC METALS LAUNCHES 40,000 METRE, FIVE-RIG DRILL PROGRAM TO ADVANCE HIGH-GRADE GOLD DISCOVERIES AND DELIVER MAIDEN RESOURCE AT FLAT GOLD PROJECT, ALASKA

Tectonic Metals Inc. has launched the largest exploration and drilling campaign in the company's history at the Flat gold project in Alaska. Backed by an approximately $100-million treasury, Tectonic is deploying five drill rigs to execute a 40,000-metre drill program that executes on four pillars of value creation: expansion and growth drilling, maiden resource definition, district-scale regional discovery drilling, and advanced project derisking and infrastructure expansion.

Initial crews have safely and successfully opened the Flat camp in April, 2026, and are rapidly upgrading infrastructure to support drilling operations, which have now officially begun.

Tony Reda, co-founder, president and chief executive officer of Tectonic Metals, commented:

"The closing of our $92-million financing is a powerful endorsement of our ongoing exploration strategy to define a bulk-tonnage, heap leachable gold mining opportunity at Flat and positions Tectonic for another transformational year ahead. We are grateful for the support of our shareholders and recognize the responsibility that comes with it. Rather than resting on our success to date, we are returning to the field earlier than ever to launch the largest drill program in Tectonic's history.

"The 2025 program gave us a glimpse into the potential size and scale of this multi-intrusion gold system and we are confident that our approach in 2026 can build on that success to better define high-grade corridors, establish resources within existing discoveries, and, target further district-scale discoveries within our vast, yet underexplored, land package. Despite our success to date, I firmly believe we are only scratching the surface.

"Our objectives for 2026 are clear: expand high-grade mineralization, make new discoveries across the property, deliver a maiden mineral resource at Chicken Mountain in Q1 2027 and begin advancing the project toward development. In parallel, we are making targeted investments in infrastructure to reduce costs, improve safety and efficiency, and position the company to execute larger-scale, year-round exploration and development programs in the years ahead."

Peter Kleespies, vice-president of exploration, commented:

"The 2025 program delivered on every objective and fundamentally expanded our understanding of the Flat system. We drilled 18,373 metres across 125 holes, maintained a 100-per-cent drill success rate at Chicken Mountain, and unlocked more high-grade mineralization, including the impressive CMR25-084 which intersected 9.94 g/t Au over 36.58 metres. Beyond Chicken Mountain, we proved even further that multiple intrusion related targets exist at Flat with a transformative drill hole at the Black Creek intrusion, six km northeast of Chicken Mountain, where hole CMR25-059 returned 4.50 g/t Au over 48.77 m from surface.

"The 2026 program builds directly on that success across every front. This is the most technically comprehensive campaign we have ever undertaken at Flat, and we believe 2026 will be another momentum building year."

2026 program overview: four pillars of value creation

Drilling is officially under way and will continue through late fall. Supported with a $100-million treasury, the 40,000-metre program (Table 1.0 approximately 30,000 m diamond core; 10,000 m RC) will drive value across four primary pillars.

1. Chicken Mountain expansion and growth drilling

Aggressive stepouts along strike, width and depth, alongside targeted expansion drilling of the higher-grade corridors and potential mining starter pits. This drilling will build upon the following previously drilled, high-grade intercepts which remain open:

• CMR25-084: 9.95 grams per tonne Au over 36.58 m, including 15.73 g/t Au over 22.86 m;
• CMR25-121: 4.05 g/t Au over 30.48 m, including 8.84 g/t Au over 13.72 m;
• CMR25-035: 3.00 g/t Au over 41.15 m, including 4.00 g/t Au over 21.34 m;
• CMR24-026: 1.22 g/t Au over 65.53 m, including 6.01 g/t Au over 6.10 m;
• CMR25-059: 4.50 g/t Au over 48.77 m, including 7.79 g/t Au over 24.38 m.

2. Delivering the maiden resource at Chicken Mountain

The Chicken Mountain intrusive complex (including the Adit and Alpha Bowl zones) is the most advanced target and primary focus of the 2026 program.

• 100-per-cent drill success rate: 191 holes drilled to date, and 191 holes have hit gold;
• Scale: 3.3 kilometres of drilled mineralized strike, widths of up to 700 metres and vertical depth exceeding 300 metres while remaining unconstrained and open in all directions;
• Chicken Mountain footprint: The mapped intrusive host rock and associated geophysical anomaly measures 6.5 km by 5.6 km.
  • Total intrusion footprint area: 6.5 km by 5.6 km equals 36.4 square kilometres;
  • Currently Drilled Area: 3.3 km by 0.7 km (700 metres) equals 2.3 square kilometres;
  • Over 93 per cent of the mapped intrusive rock and geophysical anomaly remains untested and completely wide open for new additional discoveries.
• Milestone: maiden NI 43-101 mineral resource estimate targeted Q1 2027.

3. Discovery drilling at district-scale targets and regional target pipeline growth

A minimum of 5,000 metres is dedicated to testing district-scale, intrusion-related targets across the 99,800-acre property. This extensive regional campaign is supported by foundational geology work designed to unlock the broader potential of the Flat gold project:

• Black Creek intrusion target (six km away from Chicken Mountain): aggressive follow-up on the transformative 2025 drill hole (CMR25-059: 4.50 g/t Au over 48.77 m); see press release dated Jan. 29, 2026;
• Golden Apex and Jam intrusion targets: follow-up drilling on elevated gold grades successfully intersected in 2025;
• Untested intrusion targets: inaugural drill testing at the Horseshoe, Caribou and Chicken Mountain East targets;
• Foundational geology and target pipeline: Tectonic will systematically advance its robust pipeline of regional drill targets through comprehensive soil sampling and detailed geological mapping. By targeting prospective intrusion margins, hornfels contacts and structural corridors across underexplored areas, the company aims to identify, rank and vector toward new intrusion-related gold discoveries for future drill programs.

4. Advanced project derisking and engineering studies

Tectonic is operating with a mine-builder's mind set. To support a five-rig fleet and transition Chicken Mountain toward development, the company is running critical engineering studies in parallel with strategic infrastructure investments:

• Metallurgy: a total of 15 column tests, including two-inch crush heap-leach column testing at Chicken Mountain; scoping-level metallurgical studies at Alpha Bowl to continue to evaluate future processing options and efficiencies;
• Geotechnical and hydrogeological: initial drilling to generate data for future open-pit and slope stability assessments;
• Environmental and geochemical: baseline fisheries and water quality surveys; advanced metal leaching (ML) and acid rock drainage (ARD) characterization to inform future permitting submissions.

Infrastructure ownership and camp expansion:

• Heavy machinery: acquisition of a grader, dozer, telehandler and excavator ensures reliable, in-house maintenance of the Flat airstrip and access roads, eliminating third party contractor reliance and schedule risk;
• Fuel and logistics: addition of dedicated fuel trucks and crew vehicles drastically improves the safety, efficiency and cost-effectiveness of distributing supplies across the expanded property footprint;
• Optimizing drilling costs and operation: strategic investment in camp expansion, heavy equipment, fuel infrastructure and logistics to reduce per-metre drilling costs, support future year-round operations, and even larger-scale drill programs.

About the Flat gold project

The Flat gold project covers 99,840 acres of predominantly native-owned land belonging to Doyon Ltd., a leading Alaska native regional corporations and one of Tectonic's largest shareholders. Flat is located in southwestern Alaska, near one of the world's largest undeveloped gold deposits, the Donlin gold project. The property hosts a 20-plus-kilometre volcano-plutonic complex with at least six kilometre-scale intrusion targets, five of which have now confirmed gold mineralization. Chicken Mountain, the flagship intrusion, has returned a 100-per-cent drill success rate across 191 holes and has been interpreted as a large, bulk-tonnage, heap-leachable reduced intrusion-related gold system (RIRGS) with excellent exploration upside.
