Opportunity

01. PROJECT OVERVIEW

The Flat Gold Project spans 99,840ac. of predominantly Native-owned land held by Doyon Limited, Tectonic’s second-largest shareholder and one of Alaska’s largest Native Regional Corporations. 

Flat hosts a bulk-tonnage Reduced Intrusion-Related Gold System comparable to the Fort Knox gold mine. The project’s direct link between placer gold and bedrock is well established, with Flat’s intrusions contributing 1.4Moz^* of historic placer production. Drilling returned gold in 87/87 holes – 100% drill success rate to date, outlining shallow mineralization along a 3km strike, to 325m depth, open in all directions.

Why a 100% drilling success rate? Multiple layers of geological evidence reinforce the potential for a multi-million-ounce, run-of-mine, open-pit, heap-leach operation.

02. “BIG DEPOSITS LEAVE BIG FOOTPRINTS”

Multiple Layers of Compelling Geological Evidence

1.4 Moz^* Recorded Placer Production at Flat

• 3^rd richest placer gold mining jurisdiction in Alaska^*
• Chicken Mountain credited as the primary bedrock source
• Every stream draining out of Chicken Mountain carries placer gold

District-Scale Soil and Geophysical Anomalies

• Each geophysical circular anomaly indicates a potential deposit
• Soil sampling + geophysics: a proven exploration methodology with a 100% drill success rate 

100% Drill Success Rate at Chicken Mountain

• All 87 holes intersected gold mineralization 
• 46 of 87 drill holes ending in mineralization
• 3 kms of drilled mineralized strike, 325m vertical depth – open in all directions

The Potential to Make Every Ounce Count

• Industry-leading 96% average gold recoveries from heap leach column testing at ¾ inch crushed material

03. THIRD RICHEST PLACER GOLD MINING JURISDICTION IN ALASKA^*

The Flat Gold Project, named for its proximity to the historic town of Flat, Alaska, a historic gold mining town whose legacy helped shape regional development and fueled the early gold fever that swept through the Klondike Gold Rush.

Since 1909, Flat has had a long-standing history as one of the most productive placer gold regions in Alaska, with over 1.4 million ounces historically mined from creeks draining the Flat Project area. Chicken Mountain, the Project’s primary target, is widely credited as the primary bedrock source of this placer gold.

04. POTENTIAL LOW-COST, RUN-OF-MINE, OPEN-PIT, GOLD MINING OPPORTUNITY

Indications are that gold mineralization at Flat is in part free-milling; placer gold is found within all creeks that drain the Chicken Mountain complex. This, in combination with the presence of historically mined placer gold deposits in each creek draining the host intrusion, suggests both a potential metallurgical and geological opportunity with a low-cost path forward.

Initial metallurgical heap leach column testing returned industry-leading average gold recoveries of 96% on both oxidized and fresh, non-oxidized mineralized drill core from our primary intrusion target, Chicken Mountain.

An additional phase of heap leach metallurgical column testing has been initiated on 2-inch crush in 2025 with results that are expected in Q1/Q2 2026.

05. LARGEST DRILL PROGRAM IN PROJECT’S HISTORY UNDERWAY

In 2025, Tectonic announced a new gold discovery at our Alpha Bowl target, where 2024 RC drilling returned 65.53m at 1.22g/t, including 6.1m at 6.0g/t and 1.52m at 21.72g/t Au. On the heels of this success, Tectonic raised $34M, largely backed by premier gold funds such as Crescat Capital, VanEck, and Franklin Templeton, in just four months to launch a multi-rig drilling campaign (See May 20 & August 20 News Releases).

Initial Phase-1 results have delivered encouraging grades, with RC hole CMR25-035, drilled to test the eastern edge of the Alpha Bowl System, but instead intersected 40m of 2.23g/t, including 21m of 4.00g/t and 13.25g/t over 4.57m. These results highlight three insights: 

1. The eastern edge of the system remains undefined; 

2. We are only beginning to uncover its potential; 

3. High-grade gold is present and may exist at scale.

With 47 holes pending assays and Phase-2 drilling underway, 2025 is shaping up to be a pivotal year for the Flat Gold Project.
