Castle Minerals Limited advised that a specialist review of geochemical datasets, which includes the results of a recently completed infill soil sampling program, has identified four high-priority targets for gold and possibly pegmatite-hosted lithium at the Beasley Creek project on the northern flanks of the Pilbara's Rocklea Dome granite intrusion. Castle's recognition that the under-explored older Archean greenstone sequence of rocks at Beasley Creek is prospective for structurally controlled, orogenic-style gold mineralisation is beginning to pay dividends. Results from a series of rock chip, stream sediment, soil sampling and mapping campaigns combined with a recent high resolution aeromagnetic survey and detailed structural interpretation have reinforced the belief that the area contains several viable drill targets.

Two of the priority gold targets fall within a structurally bound, northwest trending anomalous corridor in the centre of the licence. They comprise a consistently anomalous 600m zone with associated copper anomalism and a smaller anomalous gold zone with a multi-element association of sliver, bismuth, nickel, platinum and palladium. Sample values peaked at 137ppb Au and 1010ppm Cu.

Lithium: The two other priority targets have a strong lithium signature in both soil and stream sediment samples. These are located in the southern section of the greenstone rocks, close to their margin with the Rocklea Granite. Lithium and the anomalous associated pathfinder elements also identified were not a specific target for exploration at Beasley Creek but their elevated values have provided Castle with an additional dimension to its exploration in the region.

The multi-element signatures of these anomalies are consistent with possible hard rock lithium mineralisation associated with lithium-cesium-tantalum ("LCT") type pegmatites and their close proximity to the Rocklea granite provides additional encouragement. At this stage it is too early to have a firm understanding of the origin of the lithium. It is also stressed that Castle has not yet carried out enough sampling to confirm the source of the lithium or other associated elements and no pegmatites have as yet been identified in the field or are apparent from satellite imagery.

A field inspection is planned as a priority and before any decision to drill the lithium targets is made. Review details: When soil and steam sediment samples are collected, they are assayed for up to 30 different elements. Specialist consultant, Sugden Geoscience, was contracted to undertake a detailed multi-element geostatistical study that looked closely at individual and groups of `pathfinder' elements to identify areas with typical `signatures' for possible orogenic gold and VMS-style mineral deposits.

The study also effectively `levelled' the various datasets in the context of the underlying stratigraphy in order to screen out `false positives' and identify zones of bona fide anomalism.
