Castile Resources Limited provided a further update on the outcomes of the remainder of drilling results at its Rover Project, near Tennant Creek in the Northern Territory. The last two holes of the program were drilled at the Rover 4 Prospect approximately 2.1km north of the planned Rover 1 mine. Given the Iron Oxide Copper Gold (IOCG) discovery previously made at this prospect, the decline has been planned to run past Rover 4 and potentially provide an early opportunity for copper ore to be produced whilst the Rover 1 orebody is being developed.

The previous owners of Rover 4 drilled 48 holes into the deposit and Castile will now combine that data with these two new holes to produce a mineral resource estimate for the prospect. Two diamond holes were drilled at Rover 4 to validate the position of ironstone alteration and to gather valuable geotechnical information from the overlying and unconforming sedimentary rocks of the West Wiso basin within which the decline will be developed. As expected, the holes encountered the magnetite rich IOCG alteration with zones of copper mineralisation with better results including: 7.5m @ 2.0% Cu, 0.20 g/t Au from 336.0m downhole in 22CRD002, 4.2m @ 0.9% Cu with 2.9g/t Au from 363.8m downhole in 22CRD002, inc 2.4m @ 0.8% Cu with 4.7g/t Au from 365.6m downhole.

The two Rover 4 holes validated the interpretation of the IOCG alteration and in some cases extended the higher-grade zones of copper mineralisation within it. Significantly, they revealed for the first time gold mineralisation at the base of the IOCG alteration. This potentially opens up another highly prospective exploration target.

As previously announced, discovery Hole 22CRD001-2A intersected and significantly increased the size of the IOCG alteration in the Jupiter Deeps section of the ore body. This led to the interpretation of a new copper zone and a significant extension of the Jupiter Deeps IOCG alteration. For completeness, assaying was also conducted on the portion of the hole that had exited the IOCG alteration laterally at the end of the hole to assess any further mineralisation.

No significant assays were received for the portion of the hole outside of the alteration zone. However, the structure remains open at depth. Castile will now conduct a new Mineral Resource Estimate to include the new gold discovery, the Ganymede gold zone and the new IOCG alteration.
