Southern Cross Gold Ltd. has published its maiden gold and antimony Exploration Target at its flagship 100% owned Sunday Creek Project in Victoria, Australia. The Exploration Target has been developed to demonstrate the scale and high-grade gold-antimony potential of the Sunday Creek Project that has been drilled over the last year and is the first step in the pathway to a resource. The tonnage and grade are estimates based on continuity of mineralization defined by exploration diamond drilling results (previously reported including relevant sections and plans) within proximity to the intrusive "main structure" zone and bleached sediments.

Strike extents in the lower-case model are minimized to half drill spacing (~14m) or to locally restrictive geology (i.e. bounds of bleached sediment or dyke) whichever was smaller. The upper-case model strike extents were extended to the average vein strike (typically around ~40m) or to geological constraints, whichever was smaller. The Exploration Target was limited to a vertical depth of 1,003 m below surface (-710m RL), limited by the deepest mineralization defined to date within the "main structure" dyke/dyke breccia and bleached sediments within Rising Sun.

Drilling indicates Rising Sun could contain higher gold and antimony grades than Apollo and Apollo Deeps. A series of sub-vertical lodes within a 620 m-wide corridor has been outlined at Rising Sun and Apollo with mineralization remaining open to the east, west and also to depth. Only the Rising Sun and Apollo areas were considered for the Exploration Target as they contain sufficient drilling to suggest continuity and infer grade ranges.

The Exploration Target is based on the interpretation of the following geology and mineralization data that has been collated as of the date of this announcement: 116 structurally oriented drillholes for 45,971 m at the main Sunday Creek area that have been drilled by Mawson/SXG; 64 aircore, reverse circulation and unoriented diamond drill holes for 5,599 m that were drilled historically on the project; 26,513 drill hole assay results; 353 density measurements on mineralized diamond drill core, an SG of 2.75 g/cm3 was applied to the Exploration Target. surface geological mapping, costean data and diamond core geological logging; detailed LiDAR imagery; geophysical datasets including detailed ground magnetic and 3D induced polarization; wireframing and modelling of the Apollo and Rising Sun mineralized body. A total of 49 mineralized vein set shapes were created for the Exploration Target of which 42 were vein sets and 7 high-grade internal shapes (at Apollo, but not Rising Sun due to the lack of drill data) were defined.

A total of 32 of the vein set shapes had grades estimated from composited assay data, while 17 vein set shapes used the average calculated grade of either Rising Sun (lower case 5.3 g/t Au and 1.4 % Sb and upper case 8.9 g/t Au and 1.5% Sb) or Apollo (lower and upper case 4.0 g/t Au, 0.6% Sb) and this was applied to the exploration target. Drilling indicates Rising Sun could contain higher gold and antimony grades than Apollo and Apollo Deep. Mineralization across all vein sets was limited by the deepest mineralization defined to date, within the "main structure" dyke/dyke breccia and bleached sediments within Rising Sun approximately 1,000 m below surface.

While at Apollo the Exploration Target extended from surface to where drill density decreases 650 m below surface. Below drilling intercepts to the lower estimation limit, the low tonnage range used a minimum width of 1.5 m (75% of average estimated true width of domains) while the high tonnage range applied a minimum width of 2 m (average true width of domains). Strike extents in the low tonnage range model were minimized to half drill spacing (~14 m) or to locally restrictive geology (i.e. bounds of altered sediment (ASED) or dyke) whichever was smaller.

The high tonnage range model applied strike extents that were extended to the average vein strike (typically around ~40m) or to geological constraints, whichever was smaller.
