Red 5 Limited announced that recent exploration drilling at the 100%-owned South Yandal Gold Project, located 20km west of the Darlot Gold Mine in the Eastern Goldfields region of Western Australia, has delivered positive results, identifying several new zones of gold mineralisation. Two separate air-core programs totaling 5,708 metres of drilling have been completed, targeting the NW Structure target and the Coodawa Prospect. The programs were designed to test high-priority targets across the prospective but underexplored South Yandal area, proximal to the Ockerburry Shear Zone, a major regional- scale fault system linked to gold mineralisation in the region.
Gold assays from the initial 4-metre composite samples have returned promising results, identifying zones of significant gold mineralisation at both target areas. In particular, highly encouraging first-pass results were achieved at the NW Structure, where drilling intersected multiple intervals of vein-hosted gold across broad zones within the 1.2km target strike length. Initial observations show gold mineralisation is spatially associated where the north-west structures intersect stratigraphic boundaries. Importantly, many of the mineralised holes ended in anomalous gold, indicating the mineralisation continues deeper into the bedrock. Sample re-splits at 1-metre intervals from the mineralised zones have been submitted for analysis, with assays currently pending. Further drill programs, following up on these new gold intercepts and testing other high-priority areas within the prospective exploration tenure are planned. The Yandal South Project area lies within prospective and underexplored tenure approximately 20km west of Red 5's Darlot Gold Mine at the southern end of the gold-rich Yandal Greenstone belt. The area is host to the regional-scale NNE-trending Ockerburry Shear Zone, a major geological structure linked with gold mineralisation in the region and host to the 4km long and 500 metre wide Dingo Ridge Gold Prospect located in the north-
central part of the tenement package. Recent exploration drilling undertaken by Red 5 at Yandal South was directed at the NW Structure and Coodawa prospects located in the northern part of the tenure. This drilling was designed to test large-scale targets identified from data-driven exploration targeting and target refinement work using geochemical and geophysical datasets combined with field-based geological observations and learnings.
The first-pass exploration drilling completed at the NW Structure comprised 80 air-core holes totalling 4,002 metres. This program aimed to test for gold fertility across a broad structural zone hosting a series of NW- trending second-order faults, which splay off the Ockerburry Shear Zone proximal to the Dingo Ridge Prospect. The NW Structure's gold potential was first identified from rock samples taken from partially exposed subcrop
positions along the NW faults and later enhanced by a gridded ultrafine soil survey over the area. The initial results have validated the targeting model and opened a highly prospective new search space of considerable
scale. Structural interpretations from magnetic data show prospective horizons are continuous in length at the kilometre scale, highlighting the significant potential of the area to host a sizeable orogenic-style gold deposit.
All assays from the initial 4-metre composite samples have now been received, with highly encouraging results identifying multiple intervals of vein-hosted gold mineralisation across broad zones. Initial observations indicate
that gold is spatially associated with the NW structures and where they intersect with stratigraphic boundaries. The best results from the program included 4 metres @ 1.7g/t Au within a wider mineralised zone of 12 metres
@ 0.64g/t Au in hole 22DRAC0080 and 4 metres @ 1.08g/t Au from 40 metres in hole 22DRAC0082. Sample re- splits at 1-metre intervals taken from the mineralised zones have been submitted for analysis, with assays
currently pending. Importantly, many of the drill holes report significant gold mineralisation at the end of hole and at the top of fresh rock, indicating there is strong potential for the gold mineralisation to extend into the fresh bedrock. Red 5 will conduct seismic surveying over Yandal South in February and March 2023, prior to the next stage of drilling. The planned survey will cover a 12km2 area, including the NW Structure, Dingo Ridge and wider
surrounds, with the aim of mapping the subsurface to a depth of approximately 400 metres for 3D modelling of structural and lithological features for exploration target generation and drill hole optimisation over this large
exploration search space. This survey will be undertaken in collaboration with Fleet Space Technologies using near real-time ambient noise tomography technology and Exosphere data processing services.
