Further Step-Out Gold Success and High-Grade Antimony Discovery

Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) provides further assay results from its Golden Range Project, located in the Murchison region of Western Australia. The results reported in this release are for a further 6 of the 27 diamond holes drilled in the current program at Ricciardo (6 holes for 1,102m), as well as 2 diamond tails drilled at M1 and Austin (2 holes for 259m). Results for the first 14 diamond holes of the current program were previously reported (refer WA8 ASX releases dated 3 July 2024, 19 July 2024 and 2 August 2024).

HIGHLIGHTS:

• Assay results received for a further 1,102m of diamond drilling at Ricciardo.
• Extremely high-grade antimony (Sb) intersected in multiple holes below the Ardmore pit, including in RDRC067 above the main zone of high-grade gold mineralisation:
  • 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq*) from 229.2m
    incl. 1.85m @ 28.50% Sb and 0.45 g/t Au (60.94 g/t AuEq) from 238.25m
• A wide zone of antimony mineralisation was encountered in hole RDRC001:
  • 34m @ 1.0% Sb and 0.59 g/t Au (2.72 g/t AuEq) from 158.80m
• This newly identified and exceptionally high-grade Sb zone, along with the broader antimony potential at Ricciardo, demands prompt follow-up and evaluation.
• Further high-grade gold extension delivered below the Ardmore pit:
  • 18m @ 3.41 g/t Au and 0.27% Sb (3.97 g/t AuEq) from 276m (RDRC048B) incl. 4.5m @ 9.90 g/t Au and 0.01% Sb (9.93 g/t AuEq) from 286.5m
  • 1m @ 28.31 g/t Au and 2.18% Sb (32.92 g/t AuEq) from 286m (NMRC005)
  • 42.6m @ 1.08 g/t Au and 0.05% Sb (1.17 g/t AuEq) from 253.38m (RDRC067)
• ‘Golden Corridor’ diamond drilling now complete, with 31 holes drilled for 3,300m.
• All residual diamond assays expected to be received by late September, with update of the Ricciardo Mineral Resource targeted for Q4 2024.
• Further growth-focussed RC drilling of the ‘Golden Corridor’ scheduled for H2 2024, as well as planned aircore drilling along select parts of the regional shear.

Warriedar Managing Director and CEO, Amanda Buckingham, commented:

“The results for these holes successfully demonstrate further extensional high-grade gold, and for the first time very high-grade antimony zones below the Ardmore pit area.

Given the relative absence of assaying for antimony in historical drilling at Golden Range, we are cautiously optimistic on the potential that might exist here. Moreover, the apparent zonation in RDRC067 is also highly encouraging for any future antimony development potential.

I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context

The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current MRE of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.¹ Historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.

Due to the limited number of multi-element assays from historical drill holes at Ricciardo, other mineral potential (outside of gold) has also not been properly evaluated historically.

The gold mineralisation at Ricciardo is predominantly hosted with intensified altered and deformed ultramafic units. It is important to note that the newly identified antimony-dominant mineralisation identified in RDRC067 (discussed below) sits above high-grade gold mineralisation in the same area, and may overprint the earlier gold mineralisation in some areas.

High-grade antimony zone discovery below the Ardmore pit

RDRC067 was designed to drill south to north along strike to better understand the structural controls within the Ricciardo deposit and assess the continuity of the ultramafic unit (Figure 3). All previous drill holes (by Warriedar and previous explorers) have been drilled eastward perpendicular to the known mineralised structure. RDRC067 was considered an important hole by the Warriedar technical team in order to confirm there are no additional structural controls and to provide further confidence in the geological model.

Unexpectedly, RDRC067 intersected significant high-grade antimony mineralisation from 229.2m to 241.9m downhole, returning 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq) (Figure 4). Above this high-grade antimony zone, another significant zone was also identified from 183m to 198.1m downhole, returning 15.1m @ 1.42% Sb and 0.42 g/t Au (3.42 g/t AuEq) (Figure 4).

The antimony zones intersected by RDRC067 are interpreted to correlate with a lower grade antimony zone intersected in RDRC038 and RDRC049 (Figure 4). Encouragingly, drillhole RDRC001 returned a wide zone of antimony mineralisation: 34m @ 1.0% Sb and 0.59 g/t Au (2.72 g/t AuEq). Further work is required to determine the geometry and extent of the antimony mineralisation.

RDRC067 concluded at 296.96m downhole depth, within the gold mineralisation domain, as the target depth of the hole had been reached. As RDRC067 is not drilled perpendicular to the Mougooderra Shear, which is the main control of the mineralisation, it is important to note that the intersected thickness does not reflect the true thickness of the mineralisation.
