The Sunday Creek Project is a shallow orogenic (or epizonal) Fosterville-style deposit located approximately 60 km north of Melbourne and contained within 19,385 ha of both granted exploration licences and one granted retention licence.
The main historic workings at the Sunday Creek Project have been drill tested with encouraging results and remain open at depth and along strike.

Historic gold mining between 1880-1920 occurred over a greater than 11 km trend where total production is reported as 41,000 oz gold at a grade of 33 g/t gold. Drilling during 1990-2000s focused on shallow, previously mined surface workings, covering an area of 100 m in width, 800 m length but only to 80 m depth. As such, the entire field remains open along strike and to depth.
Mineralisation at the Sunday Creek Project is hosted in late-Silurian to early-Devonian-aged shales and siltstones containing a series of dykes of felsic-intermediate composition. Gold is concentrated mainly in and around the EW to NE-SW trending felsic dykes, within predominately NW oriented brittle multiple sheeted veins and cataclastic zones. Individual high-grade quartz-stibnite veins at Apollo and Golden Dyke, and cataclastic zones at Gladys were the focus of historical mining at Sunday Creek. These zones have been proven to continue to depth by SXG. Broader vein-hosted and cataclastic mineralisation grading less than 15 g/t gold appears untouched by the historic miners.
Between May 2022 and July 2023, SXG released 40 holes for 13,949 m which produced 15 individual intersections exceeding 50 AuEq g/t x m (“AuEq g/t x width in m”) and 11 individual intersections exceeding 100 AuEq g/t x m. Assays from all completed holes have been released and can be found through our announcements here.
Selected results from drilling released prior to the SXG IPO in May 2022 are set out in the table below:
Summary of key intersections drilled by Clonbinane Goldfield Pty Ltd between 2020 and May 2022 at the Sunday Creek project. Intersections are reported with a lower cut of 0.3 g/t AuEq cut over 2.0 m width, with higher grades reported with a 5 g/t AuEq cut over 1.0 m. The equation used for AuEq is AuEq=Au+Sb/1.0046 and is based on forecast long term USD prices of Sb $5,600/tonne and Au$1,750/oz.

Sunday Creek – Apollo Cross Section AS AT MARCH 2022
Cross section near Apollo Mine indicating the continuous extent of high-grade gold extending to MDDSC026 and open beyond.
Trenching work has been performed for 200 m east of the drilled area at the Apollo prospect. Trench 1 intersected 14.0 m at 11.5 g/t gold and 0.3% antimony including 8.0 m @ 19.6 g/t gold and 0.4% antimony; Trench 2 intersected 2 m @ 4.9 g/t gold and 0.2% antimony. Three other trenches had minor or no gold. Mineralisation remains open 10 km to the east of these trenches, where historic mining was common, but no drilling had ever taken place prior to SXG's maiden drill campaign at the Tonstal and Leviathan prospects in mid-2023.
Sunday Creek – Additional exploration work
In addition to the drilling and trenching described above, programs have been completed at the Sunday Creek Project including geophysical surveys (3D induced polarisation and ground magnetics), LiDAR, rock chip sampling and a 1,200-point soil sampling program extending east northeast from the drilling and trenching areas to test the 11 km trend of historic epizonal dyke-hosted mineralisation which has produced significant anomalies worthy of drill testing within SXG’s tenured areas.

Map of gold in soils as image (ranging up to 0.071 ppm Au) over LiDAR image and interpreted costeans and chains (lines) of pit workings. The LiDAR interpreted workings were created using automated (machine learning) techniques.
Freehold land acquisition
In May 2022, SXG completed the acquisition of 132 ha of freehold land that forms the key portion in and around the drilled area at Sunday Creek. We subsequently purchased a further 0.65 ha in July 2023 that is located adjacent to both the main access and existing freehold ownership at the project. We believe owning the freehold land better secures future surface access. We may consider in the future other uses for the freehold land, such as renewable energy options, livestock grazing or agistment to help maintain the property although there are no current plans for such additional uses.
