Au Gold Corp Selects the First Two High-Priority Drill Targets at its Havelock Gold-Antimony Project, Victoria, Australia

Sandrine Lam — Wed, 16 Sep 2026 11:33:00 +0000

Vancouver, British Columbia – 16 September, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to provide full details on the rationale behind the first two high-priority diamond drill targets at its Havelock Gold-Antimony project in Victoria, Australia.

McFarlane’s – diamond drilling will systematically target the down-plunge continuation of the best gold-antimony mineralization interpreted from reconstructed historical mine records dating back to the 1880’s (see August 31, 2026 press release). High-grade gold and antimony were historically mined at this target to a depth of 350 feet (107 metres (“m”)).
Shaw’s No.1 North – diamond drilling will systematically target the region below the 180 foot (55 m) level of the historic mine to test continuity of mineralization and establish potential plunge geometry of mineralized shoots. Drill holes will also test the parallel reef east of the main Shaw No. 1 workings.

Marc Blythe, Founder & CEO of Au Gold, comments, “We are extremely excited to have identified these two high-priority targets along the Shaw-McFarlane Trend which was a productive gold belt in the 1800’s. The first targets announced in this release are the McFarlane historical gold-antimony mineralization and the nearby 514 ounces of gold reportedly recovered from the Dam target in 2010, both of which initially drew AUGC to this project.”

McFarlane Target

The McFarlane target initially drew AUGC to the Havelock project with records from the 1880’s describing ultra-high grade parcels of quartz being mined and processed with gold grades in the multi-ounce per ton range. Based on historic records, the average grade of material treated is estimated to be about 23 g/t gold. Mining ceased when abundant antimony (stibnite) was encountered at the lower levels in the mine, mixed with the gold in quartz, combined with difficulties pumping out ground water.

Modern technical literature suggests high grade gold in association with abundant antimony in Victoria can be an indicator of an epizonal gold system. Other epizonal gold systems in Victoria include Fosterville (Agnico Eagle), Sunday Creek (Southern Cross Gold) and Costerfield (Alkane Resources). Each of these epizonal systems has demonstrated significant depth potential (more than 1km).

The McFarlane’s long section compilation is illustrated in Figure 1.

Figure 1

McFarlane’s mine is the most northerly of the significant workings along the SMT. The plan view in Figure 1 shows the main mine levels (180’, 250’ and 350’) from east to west which infers a steep westerly dip of the gold bearing vein(s). The detailed long section illustrates the extent of the workings along a 230 m strike length to a maximum depth of 107 m. Gold bearing reef mineralization was documented throughout the mine workings. From a drill targeting perspective, the most interesting quartz vein widths are depicted by yellow stars with the mine manager’s comments in quotes. Reef (vein) thicknesses are believed to be accurate and the mineralization is described only in a qualitative manner by the amount of visible gold and other sulphide minerals present.

Select mine manager records documenting the greatest thicknesses and occurrences of visible gold are interpreted to form a southerly plunging shoot up to 60 m wide at the base of the southern end of the workings. The 350’ level (107 m) also recorded some of the thickest vein dimensions of the entire trend at 36” (0.91 m). The occurrence of antimony mineralization is best documented in the 350’ (107 m) level where it is described as being much larger than anticipated, presumably compared to the exposure in the 250’ level. This exposure on the 350’ level is documented as 25’ (7.62 m) long which is interpreted to represent the drive length of the exposure. No orientation data is provided in the historical notes but it is currently interpreted as part of the plunging reef system. AUGC‘s phase 1 diamond drilling will systematically target the down plunge extent of the gold and antimony mineralization from the 350’ level (107 m).

A series of drill sections are also designed to test between the mine workings and the Dam target where 514 ounces of gold were reportedly recovered in recent times. AUGC believes the gold-in-quartz (previously reported) from the Dam target may represent a parallel reef system east of the main workings. Also of note is a parallel reef documented 24 m west of the main workings which was encountered in an exploration crosscut but not followed up for development. This reef discovery is described in the mine manager’s notes as a “strong body of laminated quartz 2 feet thick, highly mineralized and throwing out a strong body of water¹”.

_________________________

[1] The company interprets ‘throwing out a strong body of water’ to mean ground water was encountered when the quartz reef was intercepted.

Shaw’s No.1 North Target

The Shaw’s No. 1 mine lies in the central part of the line of significant workings on the SMT. It is a single level mine with a drive at a depth of 180’ (55 m) along a strike length of 140 m. General long section position, plan view and detail long section attributes are shown in Figure 2.

Figure 2

Similar to McFarlane’s, gold bearing reef mineralization was documented throughout the majority of the workings at Shaw’s No.1 and the select attributes denoted by the stars on Figure 2, are the mine manager’s records of the thickest and most well mineralized portions of the system.

The plan view map illustrates a parallel mineralized reef roughly 10 m east of the main Shaw No. 1 workings that is believed to have been worked in a lesser capacity by earlier miners. This parallel reef was encountered by an eastern crosscut shown on the detailed long sections.

The mineralized system at Shaw’s No.1 strikes north and is interpreted to dip steeply to the west. The strongest mineralization documented historically covers a horizontal span at the 180’ level (55 m) of approximately 55 m. Diamond drilling by AUGC will systematically target the region directly beneath this portion of the 180’ level to determine continuity of mineralization and establish potential plunge geometry of mineralized shoots. Drill holes will also test the parallel reef east of the main Shaw No. 1 workings.

Next Steps

AUGC continues to prepare for diamond drilling on the Shaw – McFarlane Trend and other peripheral targets.

The Company continues to engage with the community, in particular private landowners within areas of interest on the project. Both drill targets identified in this release require permission from private landowners. AUGC is in active discussions with both parties regarding access.

Historical Records

AUGC cautions that the historic mine reconstruction work has relied on records which pre-date the introduction of NI 43-101. The reconstruction involved collating public records, comprising public company disclosures and newspaper articles, primarily from the late 1800’s and sorting them chronologically. Some of these records are online while others are only available at certain repositories on microfilm. AUGC reminds the reader that no mineral resources exist on the project and there is no certainty that exploration will result in the definition of mineral resources, despite the reported historic production.

A visual representation of each individual mine of significance has been rendered from these records. The reader is cautioned that the information may contain inaccuracies and may be incomplete in areas. Laboratory analyses were not carried out during this era and comments on the quality of material mined are therefore subjective and based on visual inspection. The language used reflects the era in which the work took place. Tonnages of material mined and treated are detailed in the historic records, along with the number of ounces of gold produced, which were generally disclosed on a quarterly basis.

The widths of gold-bearing quartz veins encountered in these historic mines has often been recorded and ranges from 3” to 3’6” (0.075 – 1.07 m). AUGC has relied upon these historic disclosures and reconstructions to interpret its high-priority phase 1 drill targets. It should be noted that even with potential deficiencies in the historical documentation, the level of detail is considered invaluable.

Au Gold Corp Finalizes Historical Long Section Reconstruction at its Havelock Gold-Antimony Project, Victoria, Australia

admin — Mon, 31 Aug 2026 18:15:23 +0000

August 31, 2026

Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to provide details of the recent research and subsequent historical long section reconstruction along the Shaw-McFarlane Trend (“SMT” or “Trend”) at its Havelock Gold-Antimony project in Victoria, Australia.

The Company has completed its research and compiled the findings from a series of documented historical shafts (approximately seventeen) and significant workings along the central portion of the Havelock property spanning a strike length of 5 kilometers (“km”) of the 9 km Shaw-McFarlane Trend. The bulk of the historical gold production is reported from a series of mines within a 2.34 km central portion of the Trend. Figure 1 shows the Havelock southern exploration license with plan view maps of the northerly trending SMT and the distribution of the main workings in long section.

Between 1864 and 1891, the total recorded hard rock gold production from the mines along the SMT was approximately 17,097 ounces at an average grade of 28.7 grams per tonne (“g/t”) gold. The majority of this reported production is from the mines between McFarlane’s and Rob Roy illustrated on Figure 1. The most extensive series of workings are situated at Shaw’s Main where approximately 11,400 ounces of gold was extracted with the lowest level of the mine recorded at 500 feet (152 m). All other mines along the trend were worked to levels shallower than 350 feet (107 m).

Marc Blythe, Founder and CEO of Au Gold, comments, “The extensive reconstruction of these historical production records is a critical step in our understanding of the reef systems developed at Havelock. Past shallow high-grade gold production at multiple sites along the trend reinforces our belief in the potential for significant discoveries beneath the historical workings”.

Each of the past-producing mines was owned and operated by separate, publicly traded companies all now inoperative. Production reports were filed by mine managers on a quarterly basis and contained highlights, interesting developments and generalizations often only amounting to several short paragraphs. At several of the mines, documentation of parallel gold bearing reefs is reported, some of which appear to have never received follow up. One example of this is described at McFarlane’s where the mine manager reported an exploration crosscut in favourable geological conditions on the 250 foot (76 m) level. The crosscut encountered “a strong body of laminated quartz 2 feet thick, highly mineralized and throwing out a strong body of water”. There are no records of additional work on this parallel reef.

During the Havelock mining boom (1864 and 1891), much if not all of the ground was staked for mining licenses along the SMT as was much of the ground peripheral to the trend. This is visually apparent from the vast amount of shallow surface workings across large areas of the Havelock exploration license. Groups and syndicates were established forming companies which in turn sought financing to develop mines through the public markets of the day. Historical records suggest only twelve companies managed to gather sufficient funds to develop mines on their respective licenses. It is considered likely that the gaps between the reconstructed mines on the SMT long section are a function of the license holder’s inability to secure financing for development.

In addition to the reconstructed long section, records collated for each mine contain a wealth of information about the conditions, mineralization and thickness of quartz veins. AUGC is using this information to identify key sections where it believes the highest grade/thicknesses exist and to target exploration programs below these zones. During this era, grades were not assayed from samples at the mine. Gold content was obtained from actual crushing of mined material and gravity separation using stamp battery mills. The historic records provide subjective commentary about the gold content of the quartz veins, based on visual observation by mine workers.

AUGC cautions the reader that the information collated pre-dates the introduction of NI 43-101. Despite recorded historic production, no mineral resources exist on the project and there is no certainty that further exploration will result in the definition of mineral resources.

Next Steps

AUGC is currently collating and assessing all historical mine production and report data to direct the phase 1 diamond drill testing of the highest priority targets. Detailed long section target data and drill rationale will be released shortly.

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

Au Gold Corp Completes Surface Sampling and Begins Drill Targeting at its Havelock Gold-Antimony Project, Victoria, Australia

Sandrine Lam — Tue, 14 Jul 2026 11:32:00 +0000

Vancouver, British Columbia – 14 July, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to provide an update on exploration activities at its Havelock Gold-Antimony project in Victoria, Australia.

Drill targeting is now underway including discussions with drill contractors
144 focused rock samples collected at a range of targets driven by follow up from recent orientation sampling, historical soil geochemistry and reconstruction of historical workings
Reconstruction of historical workings on the Shaw-McFarlane Trend (SMT) is complete and providing key information for drill targeting
Approx. 1,000 soil samples are being collected and expected to be completed mid-July

Marc Blythe, Founder & CEO of Au Gold, comments, “As we conclude our surface sampling programs and shift towards diamond drilling, the next phase of work at Havelock is being carefully crafted to maximize our chances of success. The historic reconstructive work on the SMT has been extremely successful and is providing critical insights into the locations of the highest potential targets for drilling along the 9 km SMT.”

Rock & Soil Sampling

During June 2026, Company personnel carried out an intensive 3-week sampling program focusing primarily on targets identified from the recent orientation sampling campaign in conjunction with newly identified areas of historical soil and/or rock geochemical responses from both the Havelock southern and northern claim blocks (SMT southern extension and Sydenham) described in NR May 21, 2026.

The orientation sampling carried out in March 2026 provided key insights into the different styles of gold mineralization at Havelock, allowing the team to efficiently review and rank multiple targets optimizing discovery potential. Numerous targets sampled in June comprised in-situ vein exposures across measured widths and locally derived float samples proximal to hardrock sources. Assay results from this sampling are anticipated in August 2026.

Aside from potential anomalies generated by the current soil sampling program, AUGC does not envisage significant additional surface rock sampling at Havelock. The two recent surface sampling campaigns are considered sufficient for the first phase diamond drill targeting peripheral to the main SMT reef line. The approximately 1,000 soil samples are being collected in strategic parts of the property supplementing broadly spaced historical gold-in-soil anomalies generated by prior operators.

Historical Data Set Review

The reconstructive work carried out by Clive Willman and Associates along the SMT is now complete. This work has provided a stunning level of detail allowing AUGC to strategically design focused diamond drilling beneath the historical workings with a high degree of confidence given the absence of surficial clues. Drill targeting is also being designed for parallel and oblique structures west of the SMT reef line including Harvey’s Reef, Lund’s Reef and Ant Reef (NR08-2026). AUGC anticipates the identification of additional drill targets once the rock sample results from the most recent program are received and interpreted.

Although the Company has largely completed its review of historical data, some review work continues, specifically the northern tenement block where a number of anomalous gold samples were collected from rocks by a prior operator. As previously announced (21^st May, 2026), these anomalous samples comprise two trends, Sydenham Central and Sydenham East.

Prospecting at Sydenham East has downgraded the prospect and no further work is planned. The Sydenham Central target is still being evaluated.

Next Steps

AUGC will shortly complete its phase 2 work program at Havelock, comprising the collection of approximately 1,000 soil samples in strategic parts of the property and a further 144 rock samples. Follow up may be required for anomalous results received.

The focus has now shifted to diamond drill target selection and ranking. Discussions with private landowners are continuing and the Company has made several presentations to the local community. The company has also commenced discussions with diamond drilling contractors.

AUGC’s planned diamond drill program, which is expected to commence in Q3 2026 will constitute the first modern drilling program on the SMT.

Cautionary Note

Au Gold Corp Identifies Additional Gold Targets from Early Exploration Results at its Havelock Gold-Antimony Project, Victoria, Australia

Sandrine Lam — Thu, 21 May 2026 11:33:00 +0000

Vancouver, British Columbia – 21 May, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to 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 analysed from various locations on the project (Figure 1), returning values from below detection to 25.10 grams per tonne (“g/t”) gold. Only gold values have been received to date, multi-element 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 has 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 & CEO of Au Gold, comments, “Overall 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 (shown in Figure 1) 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 3 kilometre (“km”) 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 ppb and 25.10 g/t (Figure 2).

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 (Figure 2), seventeen 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 7 centimetres (“cm”) thickness from an area of shallow workings (< 1 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 sub gram gold samples with exception of one insitu sample from an 11 cm 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 insitu samples in the northern Havelock claim block (Figure 3). 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 centered on an insitu 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 2 km section of the Shaw-McFarlane Trend (Figure 1) 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

AUGC 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 upcoming phase 2 work program and historical data set review will provide the basis for identifying additional high priority drill targets at Havelock. AUGC’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 (“On Site”) located in Bendigo, Victoria, Australia. On Site operates under both ISO 9001 and NATA 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, AUGC did not insert additional QA/QC samples.

Au Gold Corp Rebuilding Historic Mining Database at its Havelock Gold-Antimony Project in Victoria, Australia

Sandrine Lam — Wed, 22 Apr 2026 11:35:00 +0000

Vancouver, British Columbia – 22 April, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to announce that it has engaged Clive Willman & Associates to research and reconstruct historic mining activity on the Shaw – McFarlane line of workings at Havelock Gold-Antimony project in Victoria, Australia.

Marc Blythe, Au Gold Corp.’s founder and CEO, stated, “We are delighted to have Clive assist us with reconstructing the locations and extent of the historic mines on the Shaw – McFarlane Trend (“SMT”). Portions of the SMT have been farmed, hiding or destroying geological evidence. While some of the larger historical mine dumps are preserved along the SMT, the extent of the workings can only be established from detailed historic records. Clive has successfully reconstructed historic workings on other projects by identifying, reviewing and collating historic data from a range of sources, including microfilm, archived newspapers and company records.”

See Figure 1 for site layout and target locations.

Output from Mr. Willman’s work is expected to allow the generation of cross-sections, long sections and three-dimensional representations of the historic workings along SMT. It is likely that detailed plans and sections were created during mining in the late 1800’s, however with the passage of time, these documents have been lost.

AUGC plans to use these reconstructed records to guide its upcoming drill program on targets that were documented as historically productive and along strategic portions of the SMT.

Mr. Willman, who holds a Master’s Degree in Structural Geology from Monash University, has had extensive industry experience in addition to 21 years with the Geological Society of Victoria as a Senior Geologist. He mapped across Central and Eastern Victoria with the Survey and lives less than an hour’s drive from the Havelock project.

Cautionary Note

Au Gold Corp Identifies High-Grade Gold Targets at its Havelock Project, Victoria, Australia

Sandrine Lam — Wed, 08 Apr 2026 11:35:00 +0000

Vancouver, British Columbia – 8 April, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to announce that its recent field work (see 23 March, 2026 press release), combined with historical data compilation and analysis, have resulted in the identification of priority, high-grade drill targets at the Harvey’s Reef Target (“Harvey’s Reef”) on its Havelock Gold -Antimony Project, Victoria, Australia (Figures 1 & 2).

Harvey’s Reef Target Highlights

Part of parallel vein system west of the main Shaw-McFarlane Trend (“SMT”)
One example of historic (1906) small-scale production from shallow workings reported 16 ounces (“oz”) gold from 11 short tons (“tons”) of vein material¹
Historic (1985) reverse circulation (RC) drill hole returned 1.5 metres (“m”) grading 9.24 grams per tonne (“g/t”) gold from 34.5 m deep on a parallel vein to the west
Select sample of quartz-stibnite collected during the preparation of AUGC’s independent Technical Report returned grades of 12.2 g/t gold and 1,800 ppm antimony

Marc Blythe, Au Gold Corp.’s Founder and CEO, stated, “Our highly prospective Havelock gold-antimony project has delivered its first ‘off trend’ drill target. Through our recently completed fieldwork and historical data compilation, we are highly encouraged by the tenor of historical mineralization and potential for parallel high-grade gold vein zones at Harvey’s Reef. The main occurrence at Harvey’s Reef does not appear to have been drill tested and results from the more recent RC drilling likely represent a shallow, parallel high-grade gold zone. Harvey’s Reef will be added to the list of high-quality drill targets that AUGC intends to test later in 2026.”

Harvey’s Reef

Harvey’s Reef is located 1.3 kilometres (“km”) northwest of the McFarlane Shaft on the SMT and is readily accessible by two-wheel drive roads and gravel trails. Northerly trending quartz veins occur within phyllic altered siltstones and along the footwall and/or hanging wall contacts of a local lamprophyre dyke. Late iron carbonate quartz breccia also occurs locally, proximal to historic workings.

The main occurrence at Harvey’s Reef was discovered in 1906 and is described by Howitt (1913) as occurring “directly on the wall of a large lamprophyre dyke (up to 5 m thick) striking N. 18° W and dipping 60° to 70° W. across the strata which dip east”. The quartz vein averages 30 centimetres (“cm”) thick and is historically documented on both the dyke hanging-wall and footwall contacts. Gold grades of 1 oz per ton were reported from the hanging wall while greater than 1 oz per ton was reported from the footwall. Enhanced gold grades in the footwall portions of other veins in the district are observed in modern production settings. The main occurrence at Harvey’s Reef has only received limited exploration along strike and to shallow depths (18 m at the deepest) where the mineralization locally pinched and is described with a southerly plunge.

Exploration in the 1980’s and 1990’s identified widely spaced (200 m) anomalous gold-in-soil values which led to the drilling of three RC holes and a series of rotary air blast (RAB) holes 170 m west of the main occurrence. The most significant result was obtained from

the RC drilling which returned 1.5 m grading 9.24 g/t gold from 34.5 m deep. The mineralized interval was logged as silty sandstone and shale with <1% quartz. Quartz-stibnite mineralization collected in 2025 during the Technical Report preparation and described in the 25 February, 2026 News Release (12.2 g/t gold and 0.18% antimony), roughly aligns with the potential vein trend tested by the RC drilling.

Also of note is the quartz veins and historical workings at Harvey’s Reef are situated at the headwaters of a local tributary of Four Mile Creek coincident with a section of moderate historical alluvial gold workings.

Harvey’s Reef occurs on Crown Land managed by Parks Victoria, who’s consent will be required prior to drilling, along with the consent of traditional owners Dja Dja Wurrung.

Cautionary Note

Au Gold Corp Commences Exploration at its Havelock Gold-Antimony Project, Victoria, Australia

Sandrine Lam — Mon, 23 Mar 2026 11:33:00 +0000

Vancouver, British Columbia – March 23, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to announce that it has commenced exploration on its recently acquired Havelock Gold-Antimony Project, located in Central Victoria, Australia.

AUGC’s field crew is currently on-site conducting field inspections of historical workings, mapping and rock chip sampling of a range of targets and follow up of recent and historical anomalies. The work is being focused along the Shaw-McFarlane Trend (described in the January 15, 2026 news release) and a new trend along the easternportion of the property referred to as the Oxonian Trend. The Oxonian Trend was brought to the Company’s attention during a thorough review of the data room provided by the previous operator which conducted sampling of vein material proximal to shallow historical workings intermittently along 3 kilometer (“km”) of the trend. Samples ranged from below detection limit to 26.3 grams per tonne (“g/t”) gold.

The Company is also introducing itself to the community and to private landowners, an important first step towards building a strong working relationship with local interests.

Marc Blythe, Founder and CEO of Au Gold, commented, “Au Gold plans to be diamond drilling targets on Havelock in the second half of 2026. With historical production and no modern exploration drilling on key structures at Havelock, it presents exceptional opportunity for new discoveries.”

Mr. Blythe continued, “Despite over a century of mining in one of the most productive gold fields in the world, the region is seeing renewed exploration activity and success exploring high-grade gold systems some of which are associated with critical minerals such as antimony. We hope to follow in the footsteps of highly successful Southern Cross Gold, building a bright future for Victorian gold mining.”

Option grant

The Company also announces that it has granted 4,275,000 incentive stock options to directors, officers, advisors and consultants of the company. The options were granted on March 20, 2026, are valid for five years and are exercisable at a price of $0.20. Options granted to investor relations personnel will vest in four equal tranches over twelve months, while the remainder vest immediately.
