Advanced Gold Exploration Reports High Grade Results from 2026 Silver Belle Mapping and Reconnaissance Program

Vancouver, British Columbia–(Newsfile Corp. – July 7, 2026) – Advanced Gold Exploration Inc. (CSE: AUEX) (FSE: ZF2) (OTCQB: AUHIF) (“Advanced Gold” or the “Company“) is pleased to announce the assay results from its spring mapping and sampling reconnaissance program at the Company’s 100% owned Silver Belle project in Nevada. High grade mineralization is present in at least three mineralized zones that were explored over several kilometers by small historic mines and prospects, with the most important being Phillipsburg, Silver Bell, and Mammoth/Champion.

Highlights

• 257 g/t Ag over 0.7 meters at the Pixie mine
• 192 g/t Ag, >10% Pb, 2.3% Zn and 0.1% Cu over 1 meter at the Phillipsburg mine
• 189 g/t Ag and 7.4% Zn at the Mammoth mine

The Phillipsburg manto consists of strongly oxidized gossanous replacement of a layer in carbonate rocks along the front of the Diamond Range and is recognized in several small historic mines developed along about 1.5 km of strike. Sampling returned up to 192 g/t Ag, >10% Pb, 2.3% Zn and 0.1% Cu over 1 meter (Table 1).

The Silver Bell mineralized zone consists of quartz veins with galena, sphalerite and stibnite with oxide copper minerals along bedding in a sandstone unit east of the Phillipsburg manto. A sample of the dump at the Silver Bell mine yielded as much as 131 g/t Ag, >10% Pb and > 0.1% Sb, and sampling of similar occurrences 5.5 km along strike to the north yielded 257 g/t Ag over 0.7 meters.

A third zone at the Mammoth mine consists of quartz veins in a transverse structure in carbonate rocks structurally between the Phillipsburg manto and the Silver Bell zone. Four samples from the Mammoth vein yielded 142 g/t Ag, 3.2% Pb, 1.9% Zn and 0.2% Cu over about 0.4 meters, with one of the samples reporting Pb >10%.

The Silver Belle project covers about 2,000 acres within the Diamond Mining District located 55 km north of the Eureka district that hosts large carbonate replacement deposits CRD as well as sedimentary rock hosted gold deposits. Mineralization at the Silver Belle Project is similar to that at Eureka. At Silver Belle, mineralization was mined from about 1869 to 1887 and two small smelters were operating. Although no records exist from this period, intermittent production from 1936-1955 is recorded at 851,898 oz Ag, 755,100 lbs Pb, 184,520 lbs Zn. Also a 1937 smelter shipment of 21 tons returned approximately 1,611 grams per tonne (g/t) silver (47 ounces per ton (oz/t)), 34 per cent lead, 9 per cent zinc, 1 per cent copper and 0.3 per cent antimony from underground workings.

Coordinates in WGS84, zone 11, by handheld GPS. Bold values highlight higher-grade intercepts (Ag ≥ 100 g/t, Pb ≥ 1%, Zn ≥ 1%, Sb ≥ 250 ppm, W ≥ 250 ppm). Gold assays pending. Indicated widths are sample lengths, the true thickness/widths of the mineralization are unknown.

The primary purpose of the sampling program was to re-establish and validate historic mineralization — including silver, antimony, tungsten, lead and zinc — identified within previous production workings and mine prospect pits as part of a NI 43-101 Technical Report.

Dr. Craig Gibson, QP of the technical report, stated, “The mineralization at Silver Belle is consistent with zoned carbonate replacement deposit (CRD) systems. The presence of anomalous tungsten may indicate proximity to higher-temperature portions of the mineralizing environment. Although no intrusions have been observed to date they are present at Eureka and elsewhere in the region.” Dr. Gibson continued “The mineralization at the Project is similar to that described for the CRD mineralization at the large Ruby Hill deposit at Eureka some 55 kilometers southwest of the Silver Belle project. At Silver Belle, large, mineralized targets are present and additional more-detailed exploration work in several areas is warranted in advance of a planned maiden drill program.”

Quality Control/Quality Assurance

Samples were submitted for gold fire assay and multi-element ICP analysis at Bureau Veritas and Skyline Labs, respectively, both accredited internationally recognized laboratories. Sample preparation and gold fire assays were completed by Bureau Veritas at the Sparks, NV lab; gold assays are pending. Multi-element analyses by Skyline were completed in Tucson by aqua regia digestion and ICP-OES for 31 elements. Control samples consisting of Certified Reference Materials including standard pulps and coarse blanks were inserted into the sample stream at about 1 per 20 samples, with additional blanks in mineralized zones.

Qualified Person

The exploration program was completed under the direction of Dr. Craig Gibson, a Qualified Person under NI 43-101. Dr. Gibson is preparing the Technical Report on the Silver Belle project. Information on the Eureka district has not been verified by the QP, and there is no guarantee that similar mineralization will be encountered at Silver Belle. The information on the Eureka district is solely being used as an aid in exploration work.
