Analysis

This announcement formalizes Stockade Mountain work in an NI 43-101 technical report, highlighting robust initial drill intercepts of 8.19 g/t and 9.32 g/t and untested CSAMT-defined targets. In context of earlier CSAMT results and ongoing exploration, it reinforces Stockade as a key asset. Investors should weigh this technical upside against prior disclosures of operating losses, going-concern warnings, and reliance on external financing.

Recent Company History

Over recent months, Austin Gold has focused on advancing and communicating work at Stockade Mountain and its broader portfolio. A June 2, 2026 update on CSAMT survey results and new drill targets saw the stock rise, while disclosure of a US$7.5M ATM equity program in February 2026 coincided with a notable decline. Routine governance and disclosure items around the 2026 AGM and annual documents produced modest negative moves. Today’s technical report further details Stockade work within this exploration- and funding-heavy backdrop.

8 terms

ni 43-101 regulatory

"filed a National Instrument 43-101 technical report titled "NI 43-101 Technical Report - Stockade"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

national instrument 43-101 regulatory

"has filed a National Instrument 43-101 technical report titled "NI 43-101 Technical Report"

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

qualified persons regulatory

"both "Qualified Persons" as defined by NI 43-101."

A qualified person is a named professional who holds the legal credentials and expertise required by regulators to review and sign off on technical, scientific or safety-related information in public disclosures. For investors, this functions like a licensed inspector or certified auditor: it signals that key claims — about clinical results, mining resources, or product safety — have been checked by someone officially authorized, which increases trust and reduces the chance of misleading statements.

grams/tonne technical

"intercepts being 8.19 grams/tonne ("g/t") over 4 feet (1.2 meters) and 9.32 g/t"

Grams per tonne (g/t) measures how many grams of a valuable metal are present in one tonne of rock or ore; it tells you the concentration of that metal in the material being mined. For investors this is a quick way to gauge potential value—higher g/t means more metal extracted from each tonne, which can improve revenue and lower cost per unit, much like more sugar in a batch means sweeter cookies without adding more ingredients.

controlled-source audio-frequency magnetotelluric (csamt) technical

"Interpretation of data from the 2025 Controlled-Source Audio-Frequency Magnetotelluric (CSAMT) survey"

A controlled-source audio-frequency magnetotelluric (CSAMT) survey is a geophysical technique that sends low-frequency electromagnetic signals into the ground and measures how different layers conduct or resist those signals. For investors, it matters because CSAMT helps map where minerals, geothermal fluids, or other underground resources are likely to be, reducing the chance of costly dry holes in exploration—think of it as shining a flashlight through layers of earth to reveal hidden targets before drilling.

resistivity technical

"associated with a pronounced resistivity high. Additional resistivity highs have been identified"

Resistivity measures how strongly a material opposes the flow of electric current; low resistivity means electricity flows easily, high resistivity means it does not. For investors, resistivity affects the value and suitability of materials used in electronics, power lines, batteries, and sensors—think of it like how narrow or wide a pipe affects water flow: materials with the ‘right’ resistivity can improve product performance, reduce energy losses, or open market opportunities, while the wrong resistivity can limit demand or require costly processing.

stockwork mineralization technical

"known lower grade stockworks mineralization. Austin's initial three holes confirmed that"

A stockwork is a dense network of many small, intersecting mineral-filled veins or fracture systems within a rock, like a sponge threaded with tiny metal-bearing channels rather than one big pocket. For investors, it matters because this style of mineralization can mean a large volume of ore spread throughout a deposit that may be suited to bulk-mining methods but often has mixed grades and variable recoveries, affecting project economics and risk.

rhyolite domes technical

"may represent similar mineralized zones hosted by rhyolite domes."

A rhyolite dome is a rounded, hill-like pile of very thick volcanic rock that forms when stiff, silica-rich lava oozes out of a vent and hardens close to the surface — think of a dollop of cooling, sticky honey that keeps its shape. For investors, these domes can concentrate valuable minerals and influence groundwater and geothermal potential, while also posing construction and hazard risks that affect mining, real estate and energy projects.

Highlights

• Austin Gold has filed a report titled "NI 43-101 Technical Report, Stockade Mountain Project, Malheur County, Oregon, USA."

Vancouver, British Columbia--(Newsfile Corp. - June 11, 2026) - Austin Gold Corp. (NYSE American: AUST) ("Austin" or the "Company") has filed a National Instrument 43-101 technical report titled "NI 43-101 Technical Report - Stockade Mountain Project, Malheur County, Oregon, USA", with an effective date of March 2, 2026 and a release date of June 5, 2026 (the "Technical Report"). The Technical Report is available under the Company's profile on SEDAR+ at www.sedarplus.ca and was prepared by Barbara Carroll, CPG, RM of GeoGRAFX Consulting, LLC and Robert M. Hatch, SME RM of Volcanic Gold & Silver LLC, both "Qualified Persons" as defined by NI 43-101. Barbara Carroll is independent of Austin and Robert M. Hatch is Austin's Vice President, Exploration.

The Technical Report documents known historical work completed on the property, Austin Gold's exploration activities to date, and recommends further exploration work for discovery of potential economic mineralization.

Stockade Mountain is a classic low-sulfidation/hot springs gold and silver exploration-stage project with a history of significant exploration work in the late 1980s and early 1990s. At that time, targeted mineralization was near-surface gold deposits minable by open pit methods. The last historical exploration holes drilled at Stockade were in 1993 by Placer Dome, and until Austin's 2023-2024 drill program, no drilling had targeted high-grade veins minable by underground methods that are hypothesized to occur below the known lower grade stockworks mineralization. Austin's initial three holes confirmed that the mineralizing system at Stockade Mountain is robust and contains significant gold grades, with the strongest intercepts being 8.19 grams/tonne ("g/t") over 4 feet (1.2 meters) and 9.32 g/t over 2.7 feet (0.82 meters).

Interpretation of data from the 2025 Controlled-Source Audio-Frequency Magnetotelluric (CSAMT) survey reveals considerable complexity in the subsurface geology at Stockade Mountain. The known gold-bearing stockwork mineralization at the Opal Hill/Number 9 Vein target area is associated with a pronounced resistivity high. Additional resistivity highs have been identified at depth and may represent similar mineralized zones hosted by rhyolite domes. These highs, along with strong contrast zones between high and low resistivities, offer untested drill targets.

The potential for the discovery of gold and silver mineralization within the Stockade Mountain Project area is considered to be favorable, and further exploration work is warranted to better define and test the identified exploration targets. There is no certainty that the present exploration effort will result in the identification of a mineral resource or that any mineral resource that might be discovered will prove to be economically recoverable.
