ADVANCED GOLD REPORTS THE SALE OF ITS MELBA GOLD PROPERTY FOR CASH AND SHARES

On Sept. 22, 2025, Advanced Gold Exploration Inc. and Heritage Mining Ltd. entered into an asset purchase agreement, pursuant to which the company agreed to sell to the purchaser its 75-per-cent legal and beneficial interest in several mineral claims comprising the Melba property.

As consideration for the Property, the company shall receive: (i) $50,000 payable in cash, for technical services, over a period of 12 months (being equal instalments of $4,166.67); and (ii) such number of common shares in the capital of the purchaser equal to $350,000, issuable to the company in four equal tranches.

Completion of the proposed transaction contemplated by the agreement remains subject to the purchaser completing due diligence on the property, the approval of all regulatory and other approvals, including the approval of the Canadian Securities Exchange.

Jim Atkinson, chief executive officer of Advanced Gold, commented: "We are excited to become a large shareholder of Heritage Mining through the sale of our interest in the property. We are confident that the management of the purchaser have the funds and the expertise to advance the project. The purchaser also has large landholdings in Northwestern Ontario with potential for gold mineralization, and we are convinced that the company will benefit from the advancement of these grounds, as well as the continued exploration of the property. The signed agreement gives the company immediate cash and shares, and will also result in future share issuance, which can be used in a non-dilutive way to advance the company."

About the property

The land package is located on a major geological feature in the Timmins- Kirkland Lake camp and is on strike with McEwan Gold's Black Fox and the former Ross mine.

The Melba mine development commenced in 1936 and ceased on the declaration of the Second World War. Nordex Explosives financed work on the property and gained ownership of 16 patent claims, including the mine site. Nordex Explosives was acquired by EPC Canada, a large explosive company from Europe. On the June 1, 2020, the patents were posted for staking as no work or lease payments had been completed except for lease 109680, totalling five claims, including the mine workings, which is in good standing until 2036.

The lease was purchased from EPC Canada, which includes a 2-per-cent net smelter return (NSR) royalty, which may be purchased in full for $500,000. Patrick Culhane presently holds 76 claims on strike, contiguous, including the mine site.

The gold mineralization on the property is open on strike and in depth; there are excellent work records for study. The lease 109680 includes five claims and the mine workings, and is in good standing until 2036. At least four gold-bearing veins are found on surface and diamond drill holes have intersected the veins at depth in previous drilling programs. The deepest diamond drill hole to date is by Melba Mines Ltd., No. 37-14, 391.52 feet, 45-degree angle. The report on March 26, 1938, over the signature of J.E. Gill, recommends sinking the shaft two additional levels 300 and 500 feet. The report ministry of northern development and mines 42A08SE2005, Gleeson-Ross mine, page 10, indicates the Melba mine site includes the geological signature similar to the Ross mine, which is situated to the northwest on strike, in Holtyre.

The property is readily accessible, and is situated approximately 25 kilometres north of Kirkland Lake, and 15 kilometres from the village of Holtyre, and the former Ross mine between provincial highways 11 and 101. Former logging roads allow access to the western edge of the property and a former mine road will allow access to the mine site after some brushing and rehabilitation.

The property consists of 68 claim units and one lease situated in Melba township.

History of the Melba mine

The Melba mine development commenced in 1936 and ceased on the declaration of the Second World War. Nordex Explosives financed work on the property and gained ownership of 16 patent claims, including the mine site. Nordex Explosives was acquired by EPC Canada, a large explosive company from Europe. On the June 1, 2020, the patents were posted for staking as no work or lease payments, except for lease 109680, of five claims, including the mine workings, in good standing until 2036.

Mineralization

Four gold-bearing quartz-calcite veins were prospected and trenched on the property. These include the Rolling vein, Mike vein, Blue vein and Contact vein. Of the veins, the Blue vein is the most important and upon which the underground work was completed. A small wedge of metavolcanics has been faulted into an area of metasediments. The rocks are intruded by a monzonite dike and several hornblende diorite dikes. The Blue vein occurs in greywacke and runs parallel to the faulted contact between the andesite and greywacke.

The Blue vein was traced for 600 feet (300 metres), with the best gold showings on the eastern 180 feet (ft) (55 metres (m)). All 20 diamond drill holes completed in this area intersected the Blue vein, with visible gold reported in 10 of the first 18 holes. DDH No. 18 intersected a second vein north of the Blue vein that ran 0.293 ounce per ton (oz/t) (9.7 grams per tonne (g/t) gold (Au) over 0.5 metre). In underground work on the Blue vein, a 200 ft (60 m) section was reported to have 0.371 oz/t gold over three feet ((12.7 g/t over one metre). The face sampling ran up to 0.385 oz/t gold over 40 inches for 169 ft (13.2 g/t over 1.1 m for 51.1 m). In 1939, sampling by the Teck-Hughes Mines Ltd. returned an assay of 0.327 oz/t Au over 4.5 ft (11.2 g/t over 1.4 m) and the bulk sample returned 0.210 oz/t Au over 4.5 feet (1.5 m).

Sampling of drill holes by Pitchvein Mines Ltd. returned values ranging up 3.5 ounces (120 g/t) over narrow width. Samples from the underground workings returned assays as high as 3.7 ounces per ton (128 g/t). Silver values in DDH S 62-1 returned values up to 0.22 oz/t Ag.

Sampling by Pitchvein Mines in 1960 returned assays from the Blue vein as high as 0.471 oz/t Au over 3.2 ft for 170 ft (161.5 g/t over 1.1 m for a length of 52 m). The Breccia vein returned 0.658 oz/t Au over 3.1 ft (22.6 g/t over 1.1 m). Gold values from the 1960 drilling by Pitchvein Mines returned values up to 1.11 oz/t Au over 2.4 ft (37.7 over 0.7 m).; most of the drill holes returned visible gold.

Mineralization on the Melba property is characterized by lode-style quartz veins and silicified brittle shear zones. Most of the historical work conducted on the property has been focused on the occurrences that comprise the main veins. The surrounding and on-strike units have never been drilled. Auriferous quartz veins are the most prospective mineralization style and generally are discontinuous, echelon tension veins probably related to offsets of the Regional Porcupine-Destor fault, which occurs to the north.

Recent drilling has exposed a new style of mineralization comprising porphyry dikes with disseminated pyrite. Anomalous gold is seen across the width of the dikes with thickness up to eight metres. This target has never been explored.
