Key Terms

diamond drilling technical

"The Work program will consist of at least 500 meters of Diamond Drilling..."

Diamond drilling is a method that uses a rotating drill with industrial diamonds on the bit to cut and retrieve cylindrical rock samples (cores) that preserve the sequence of underground layers. For investors, these cores act like a geological “biopsy,” providing direct, verifiable information about mineral presence, grade and continuity—data that underpins resource estimates, project valuation, drilling risk and financing decisions.

massive sulphide technical

"The 2022 drill program outlined a zone of massive sulphide of VMS-Type..."

A massive sulphide is a dense, rock body made mostly of metal-bearing sulphide minerals such as pyrite, chalcopyrite, sphalerite or galena; think of it as a concentrated blob of metal-rich material within the earth. Investors care because these accumulations can host commercially valuable metals (copper, zinc, lead, nickel, sometimes gold or silver), and their size and concentration determine whether a mineral deposit can be mined profitably.

pyrite technical

"The massive to semi-massive sulfides which are dominantly pyrite and pyrrhotite..."

Pyrite is a common metallic mineral made of iron and sulfur, often called “fool’s gold” because its shiny, brassy appearance can be mistaken for real gold. For investors, pyrite matters because its presence influences ore value and processing costs—it can dilute precious metal grades, increase sulfur-related treatment and environmental cleanup expenses, and create acid runoff risks at mining sites, much like unexpected rocks in a gravel pile that change what you can do with the load.

pyrrhotite technical

"The massive to semi-massive sulfides which are dominantly pyrite and pyrrhotite..."

Pyrrhotite is a naturally occurring iron‑sulfur mineral often found in rock and ore deposits. It can slowly change when exposed to air and water, producing expansion and corrosive byproducts that damage concrete, foundations and buried infrastructure. For investors, pyrrhotite is important because its presence can reduce the value of real estate, raise construction or remediation costs, and affect mining project economics — like finding hidden termites in a building that can trigger large, unexpected repairs.

chalcopyrite technical

"with chalcopyrite and sphalerite and rarely galena."

Chalcopyrite is a common copper-bearing mineral (a copper-iron sulfide) that often looks brassy yellow and is the main source of mined copper worldwide. For investors, its presence and abundance in a rock deposit determine how much recoverable copper a mine can produce and how profitable extraction will be — think of chalcopyrite as the concentrated ingredient that makes an ore body valuable and worth developing.

sphalerite technical

"with chalcopyrite and sphalerite and rarely galena."

Sphalerite is a mineral made mostly of zinc sulfide and is the main source of zinc mined worldwide; it can contain varying amounts of iron and appears in a range of colors. Investors care because the quantity and quality of sphalerite in a deposit determine how much zinc can be produced and at what cost, which influences zinc supply, industrial demand and commodity prices — similar to how the size and quality of an apple crop affect juice producers' costs.

national instrument 43-101 regulatory

"defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects..."

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.

Toronto, Ontario--(Newsfile Corp. - December 1, 2025) - Advanced Gold Exploration (CSE: AUEX) (FSE: HZ2) (OTC Pink: AUHID) ("Advanced Gold" or the "Company") is pleased to announce the commencement of a follow up drill program on it's 100% owned Buck Lake property in Ontario Canada.

Highlights

• At least 500 meters of drilling at Buck Lake Property
• Testing high-grade copper mineralization in a VMS-Type geological environment discovered in 2022 drilling
• Drilling to commence immediately - drill on-site

The fully permitted Buck Lake Property consists of a total of 180 single-cell mining claims that covers 3,886 hectares located in Lunkie and Gapp Townships in the Batchewana Greenstone Belt of Northern Ontario.

The Work program will consist of at least 500 meters of Diamond Drilling, base metal and gold assaying and reporting. A diamond drill has been deployed to the property and is scheduled to commence drilling immediately. The objective will be to test extensions of the high-grade copper mineralization discovered by drilling in 2022. Notably, high-grade silver (up to 98 g/t) accompanied the higher-grade copper mineralization. Copper and/or zinc mineralization was intersected in 13 of the 15 holes completed in 2022 generally in zones 3 to 4 meters thick.

The highest copper results returned in the 2022 drilling program was in drill hole BL-22-06 which returned a value of 4.59 % Cu over 3.2 m in a larger zone of 11.75 m of 1.51% Cu. Drill holes BL-22-14 and BL-22-15 also intersected copper mineralization with assays of 0.42 over 4.15 meters and 2.38% over 2.95 meters.

"We are pleased to be back drilling at Buck Lake prior to year-end," commented Mr. Arndt Roehlig, President and CEO of Advanced Gold Exploration. "The 2022 discovery hole of 4.59% copper over 3.2 meters within a broader 11.75-meter zone grading 1.51% copper, together with strong silver values up to 98 g/t, confirmed the presence of a significant VMS system. With only 500 meters of a 3,000-meter-long EM anomaly tested to date, the current program is designed to rapidly expand the depth and continuity of this high-grade copper zone and demonstrate the scale potential that Buck Lake clearly possesses."

The 2022 drill program outlined a zone of massive sulphide of VMS-Type contained in a mixed sequence of volcanic units consisting of felsic and mafic volcanics with tuffaceous and agglomerate textures. The massive to semi-massive sulfides which are dominantly pyrite and pyrrhotite with chalcopyrite and sphalerite and rarely galena. The sulphide zones are often enclosed in silicious material and exhalate and are often accompanied by chloritic alteration. The zone is contained in a 3000-meter-long EM anomaly which has only been explored over approximately 500 meters.

The environment is typical of VMS-type deposits such as Kidd Creek in Timmins and Horne in Noranda. Notably, VMS deposits occur in clusters as can be seen in Mattagami and in NW Quebec (Millenbach, Ansil, Corbet etc.).

A NI43-191 Technical Report Prepared by Mr. Mike Kilbourne P.Geo. in 2023 states that the geological environment of the Property is favourable for the presence of Archean volcanogenic massive sulphide deposits("VMS"), iron deposits and orogenic gold deposits, namely banded iron formation ("BIF") hosted gold deposits due to the fact that BIF's are present on the Property. The focus of exploration has historically been on VMS-type deposits, but other deposit model types should not be dismissed.

The Buck Lake Property has high potential. There are an additional eight prospective areas based on the presence of Base Metal Mineralization identified in historical or recent activities. Including areas of copper and zinc mineralization seen in past drilling and recent prospecting.

Assays results will be announced upon receipt.
