Highlights
- Catalina Resources has confirmed and expanded gold mineralisation at the T8 target, with multiple drill intercepts demonstrating continuity across the prospect.
- The T8 discovery lies approximately 14 km south of the Chicken Little prospect, supporting the presence of multiple mineralised centres along the Yerilgee corridor.
- Gold mineralisation has been identified across different rock types, indicating a broader system with further exploration areas remaining untested.
- Assays are pending from Phase 1 drilling campaign at Chicken Little.
Catalina Resources Limited (ASX:CTN) has reported new drilling assays from the Yerilgee Project in Western Australia, confirming and expanding gold mineralisation at the T8 target. The results form part of the company’s Phase 1 drilling campaign, covering 8,694m of RC and aircore drilling across the Central Yilgarn Project.
Drilling Expands Mineralisation at T8
Notable intercepts from drilling at the T8 prospect include
- 5m @ 1.38 g/t Au from 97m, including 2m @ 2.95 g/t Au and 1m @ 4.65 g/t Au (26YGRC007)
- 8m @ 0.59 g/t Au from 109m, including 3m @ 0.95 g/t Au (26YGRC005)
- 3m @ 1.23 g/t Au from 33m (26YGRC008)
The results indicate the presence of a continuous system along strike and across several host lithologies within a major regional structural corridor.
Connection to Chicken Little and Corridor Scale
The T8 target is located around 14 kilometres south of the Chicken Little prospect, where earlier drilling returned 48 metres at 2.61 g/t gold.
These results (from both T8 and Chicken Little) indicate that the Yerilgee structural corridor hosts multiple mineralised centres over a significant distance.
The identification of mineralisation at both locations supports the interpretation of a continuous gold system extending the corridor, reinforcing the district scale exploration potential of the Central Yilgarn Project.
Geological Insights and System Continuity
Drilling has confirmed that gold mineralisation occurs in both banded iron formation (BIF) and mafic rock units. In northern areas, mineralisation is associated with magnetite-rich BIF, while further south, gold mineralisation is hosted within amphibolite and mafic metavolcanics.
The alignment of drilling results with soil gold anomalies and magnetic features has supported the company’s targeting approach. These correlations highlight additional zones along the corridor that remain untested.
Phase 1 Program and Next Steps
Phase 1 drilling campaign is now complete and assay results from additional drilling at Chicken Little and other prospects are still pending.
Moving forward, the company is integrating geological, geochemical and geophysical data to refine its exploration model. Follow-up drilling is expected to focus on extending mineralisation along strike and at depth, particularly across untested anomalies within the Yerilgee corridor.
In conclusion, with multiple mineralised centres now identified across a 14 km corridor and additional assay results pending, Catalina Resources is set to advance the next phase of exploration aimed at further delineating the scale and continuity of this developing gold system within the Central Yilgarn Project.
