AU GOLD CORP IDENTIFIES ADDITIONAL GOLD TARGETS FROM EARLY EXPLORATION RESULTS AT ITS HAVELOCK GOLD-ANTIMONY PROJECT, VICTORIA, AUSTRALIA

Au Gold Corp. has provide an update on exploration activities and analytical results received to date at its Havelock gold-antimony project in Victoria, Australia.

• Eighty-nine orientation rock samples were collected and analyzed from various locations on the project, returning values from below detection to 25.10 grams per tonne gold. Only gold values have been received to date; multielement results, including antimony are pending.
• Two new areas of interest have been identified on the northern claim block through historical data review proximal to the Sydenham Reef mine (owned by a third party).
• Historic soil geochemistry data have been acquired and added to the project digital data set, resulting in the identification of anomalous gold results on the southern end of the Shaw-McFarlane trend, between Shaw's Reef and the southern property boundary. The anomalies appear to have had no follow-up to date
• Field personnel are mobilizing to collect an additional 1,000 soil samples, comprising infill and extension around existing anomalies. Further prospecting, sample collection and interpretation will be carried out during June, 2026.

Marc Blythe, founder and chief executive officer of Au Gold, commented: "Over all, we are very pleased with progress to date at Havelock. We are progressing a very methodical approach, including wringing as much information out of historical work by others at the project as possible to ensure that our own work programs are tightly focused and efficient."

First-phase orientation rock sampling results

During March, 2026, company personnel collected 89 orientation rock samples, comprising both select and in situ samples at a range of sites across the project. Target areas included two sites along the main Shaw-McFarlane Trend (SMT) reef line and several historical sites to the west assessing parallel structures including potential extensions of Harvey's Reef. In addition, a three-kilometre portion of the Oxonian trend was prospected.

Samples consisted dominantly of massive to thinly laminated quartz reef material and iron carbonate/iron oxide quartz breccias. Samples were collected from historical dump piles and shallow pits as well as undisturbed areas. Twenty-eight samples returned anomalous gold values between 100 parts per billion and 25.10 grams per tonne.

At Harper's Reef, located on the Shaw-McFarlane trend, two samples returned anomalous gold values of 0.98 and 18.40 g/t gold. The 18.40 g/t sample consisted of a composite of weakly laminated white quartz pieces collected from the top of the Harper's Reef dump pile and the grade is in line with reported historic production records. This appears to be the only sample documented from this site.

Between McFarlane Shaft and Harvey's Reef, 17 samples returned anomalous gold values between 100 ppb and 25.10 g/t. The sample grading 25.10 g/t was a composite of laminated quartz reef material averaging seven centimetres thickness from an area of shallow workings (less than one m deep) referred to in the historic literature as Lund's Reef. Angular blocks up to 30 cm thick of hydrothermally altered siltstone containing quartz stringers, secondary manganese and siderite returned 6.58 g/t gold from a parallel series of shallow workings known as the Ant Reef.

Prospecting and localized sampling along the Oxonian trend returned mostly subgram gold samples with exception of one in situ sample from an 11-centimetre exposure of quartz-siderite, which graded 3.74 g/t gold.

Recent completion of the Havelock data set review identified two well-defined northerly trends of gold-bearing float and in situ samples in the northern Havelock claim block. This region of the project is host to the Sydenham Reef mine developed along the northern extension of the Shaw-McFarlane trend. The mine is currently owned by a third party and believed to be inactive.

The two trends are delineated by rock samples grading between 0.79 g/t and 24.10 g/t gold. The rock samples were contained in a historical data set and appear to have had no follow-up. The Sydenham Central trend of anomalous rock samples is 210 m in length and is centred on an in situ sample returning 24.10 g/t gold; however, the thickness of the sample was not provided. The Sydenham East trend of anomalous rock samples is 500 m in length, with peak values of 14.20 g/t and 11.90 g/t gold at the southern and northern ends of the trend, respectively.

Historical data set review

Part of the recent data set review included the identification and location of historical soil sampling results. These were added to the digital data set, which led to the identification of a strategic two-kilometre section of the Shaw-McFarlane trend in the southern part of the property containing weak and moderate intermittent gold-in soil anomalies. There are no recorded rock samples in this area, suggesting no follow-up work has been conducted.

Next steps

Au Gold will be commencing its phase 2 work program at Havelock shortly, which will consist of the collection of approximately 1,000 soil samples in strategic parts of the property supplementing broadly spaced historical anomalies. Focused prospecting will also continue along the Shaw-McFarlane and Oxonian trends.

The recent sampling results, along with the coming phase 2 work program and historical data set review, will provide the basis for identifying additional high-priority drill targets at Havelock. Au Gold's drill program, which is expected to commence in Q3 2026 will constitute the first modern drilling program on the SMT.

The company continues to engage with the community, in particular private landowners within areas of interest on the project.

Sample analysis

Analytical samples were transported by company personnel to On Site Laboratory Services, located in Bendigo, Victoria, Australia. On Site operates under both ISO 9001 and NATA (National Association of Testing Authorities, Australia) quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25-gram charge), followed by measuring the gold in solution with flame AAS equipment. On Site inserts blanks and standards into the analytical process; Au Gold did not insert additional quality assurance/quality control samples.
