Both holes intersected multiple high-grade structures and were successful in extending mineralization beyond the bounds of the modelled mineralized domains as well as defining continuity in other areas.
Highlights: SDDSC115A intercepted eleven high-grade mineralized structures atRising Sun over a downhole width of 365.7 m from 512.4 m. This hole contains six assayed intervals of > 50 g/t Au (up to 202 g/t Au), and five assayed intervals > 5% Sb (up to 26.3% Sb) with drill highlights: 1.5 m @ 12.4 g/t AuEq (10.6 g/t Au, 1.0% Sb) from 532.6 m 3.3 m @ 6.4 g/t AuEq (2.6 g/t Au, 2.0% Sb) from 563.6 m 0.2 m @ 25.9 g/t AuEq (15.4 g/t Au, 5.6% Sb) from 573.7 m 10.4 m @ 3.0 g/t AuEq (1.2 g/t Au, 1.0% Sb) from 580.0 m 3.2 m @ 48.2 g/t AuEq (45.3 g/t Au, 1.5% Sb)from 643.4m (ETW 2.5 m) 0.3 m @ 87.2 g/t AuEq (86.4 g/t Au, 0.4% Sb) from 707.7 m 0.1 m @ 95.3 g/t AuEq (87.1 g/t Au, 4.3% Sb) from 719.5 m SDDSC117 was drilled to test strike continuity of two high-grade targets in the footwall of the mineralized host and intercepted eight mineralized structures.

The SXG Board has approved plans to drill 60 km over the next year, with a fifth drill rig to commence within weeks and a sixth rig to arrive during
SXG is commencing a specialized navigational ('NAVI') downhole application utilizing down hole motors to undertake detailed drilling (at approximately 20 m spacing) around super high-grade areas with the aim to build further confidence of grade continuity between high-grade intersections.
Seven drillholes at Sunday Creek are currently being processed and analyzed, with 4 holes in progress.
Mawson owns 96,590,910 shares of SXG (51%), valuing its stake at
'Both holes reported here also each delivered a >100 g/t AuEq x m intersection. The project now contains a total of thirty-eight (38) of these significant hits. Importantly, the frequency of these significant hits continues to increase as we drill towards depth and understand the controls on high-grade mineralization better.
'With a 60 km drill program set to more than double the drill metres into the Sunday Creek project over the next year, SXG will expand this globally significant gold discovery via logical step outs along strike to increase volume along with the start of detailed controlled downhole NAVI-drilling program that aims to target continuity of super high-grade areas.
'Additionally, planning for a regional scale IP geophysical survey is underway that will test the 10 km long trend along strike from the core drilled area to further demonstrate the district scale potential of Sunday Creek.'
Drill Hole Discussion
Two drillholes (SDDSC115A and 117) are reported from the
SDDSC115A was designed to test the footwall position of two high-grade vein sets and intercepted 11 mineralized structures, five of which are high-grade. This hole contains six assayed intervals of > 50 g/t Au (up to 202 g/t Au), and five assayed intervals > 5% Sb (up to 26.3% Sb). The hole traversed through the centre of the dyke/breccia host and provided continuity information in the plane of the 11 vein sets. High-grade continuity is well demonstrated in vein set RS55_L where SDDSC115A drilled 3.2 m (ETW 2.5 m) @ 48.2 g/t AuEq (45.3 g/t Au, 1.5% Sb) from 643.4m (2 m @ 0.5 g/t Au lower cut) including 1.3 m @ 90.2 g/t AuEq from 643.4 m and 0.3 m @ 116.1 g/t AuEq from 646.3 m, which was located 68 m down-plunge of previously reported SDDSC107 (4.7 m @ 76.6 g/t AuEq), suggestingthe possibility of a new high-grade mineralized domain.
Increasing Drilling Program
The SXG Board has approved plans to drill 60 km over the next year, with the fifth drill rig to commence within weeks and a sixth rig to arrive during
Over the next week SXG will commence a NAVI drilling program. NAVI drilling is a specialized drilling application utilizing down hole motors to make alterations to the direction of a diamond core drill hole. Detailed drilling (at approximately 20 m spacing) will be undertaken around super high-grade areas with the aim to build further confidence of grade continuity between high-grade intersections by drilling branch holes off an already drilled 'parent hole'.
Regional Programs
A large regional induced polarization survey over the 10km district-scale strike is now being planned to test the regional trend beyond the core drill area at Sunday Creek. The survey is planned to start in
No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. During future Mineral Resource studies, the requirement for assay top cutting will be assessed.
Technical Background and Qualified Person
The Qualified Person,
Analytical samples are transported to the Bendigo facility of On Site Laboratory Services ('On Site') which operates under both an 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. Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-MS analysis. The QA/QC program of
MAW considers that both gold and antimony that are included in the gold equivalent calculation ('AuEq') have reasonable potential to be recovered at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by
MAW considers that it is appropriate to adopt the same gold equivalent variables as
AuEq = Au (g/t) + 1.88 x Sb (%).
Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, SXG considers that a AuEq = Au (g/t) + 1.88 x Sb (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.
