SOUTHERN CROSS Gold Consolidated Ltd. announced that two further diamond drill rigs will mobilize to Sunday Creek next week to increase the total number to eight rigs operating at the 100%-owned Sunday Creek gold-antimony project in Victoria, while multiple geophysical and soil programs continue. Increased diamond drill rigs mobilized: Two further diamond drill rigs will mobilized to Sunday Creek over the next week to increase the total total number to eight rigs operating, with the two additional rigs to focus on infill drilling. In summary: Seven rigs will continue expansion and infill drilling in the 1.5 km long core drill area between Apollo and Christina.

One rig will be dedicated to drilling regional targets along the 12 km mineralized trend and parallel trends, defined by historic workings, geophysics, geology and soil anomalies. For the next month, one rig will complete a geotechnical program (5 holes for 900 m) to establish the detailed nature of fault structures and rock quality in the areas of planned underground development for the Exploration Tunnel. This drill program, complemented by groundwater monitoring and environmental studies, will provide essential data to support the Exploration Tunnel application scheduled for third quarter 2025 (announced 11th March, 2025).

The drilling program continues to advance with fifteen holes (SDDSC149, 149W1, 152, 155, 157-161, 155A, 157A, 160W1, 163, 164, 165) currently being processed and analysed. On Site gold method by fire assay code PE01S., Screen fire assay is used to understand gold grain-size distribution where coarse gold is evident., ICP-OES is used to analyse the aqua regia digested pulp for an additional 12 elements (method BM011) and over-range antimony is measured using flame AAS (method known as B050). Soil samples were sieved in the field and an 80 mesh sample bagged and transported to ALS Global laboratories in Brisbane for super-low level gold analysis on a 50 g samples by method ST44 (using aqua regia and ICP-MS).

Grab and rock chip samples are generally submitted to On Site Laboratories for standard fire assay and 12 element ICP-OES as described above., Drilling techniques, Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). HQ or NQ diameter diamond drill core, oriented using Boart Longyear TruCore orientation tool with the orientation line marked on the base of the drill core by the driller/offsider., A standard 3 metre core barrel has been found to be most effective in both the hard and soft rocks in the project., Drill sample recovery, Method of recording and assessing core and chip sample recoveries and results assessed., Core recoveries were maximised using HQ or NQ diamond drill core with careful control over water pressure to maintain soft-rock integrity and prevent, Criteria, JORC Code explanation, Commentary, Measures taken to maximise sample recovery and ensure representative nature of the samples., Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material., loss of fines from soft drill core. Recoveries are determined on a metre-by-metre basis in the core shed using a tape measure against marked up drill core checking against driller's core blocks., Plots of grade versus recovery and RQD show no trends relating to loss of drill core, or fines., Logging, Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies., Whether logging is qualitative or quantitative in nature.
