The Oakover West project comprises both 100% owned and Carawine JV tenure covering an area of 750km², adjacent to the Sunday and Ant Hill manganese development projects owned by Resource Development Group (ASX:RDG) and the historic Davis River manganese mine.
The geology of the tenements comprises a series of major north-trending fault bounded horst and graben structures with Pinjian Chert forming extensive plateaus and Manganese Group sediments sub-cropping within the open valleys. Manganese across the tenements is associated with sub-horizontal manganese enriched units of the lower Manganese Group sediments and sub-vertical brecciated fault structures.
Bedded manganese enrichment from the E46/1119-I
Stratabound manganese mineralisation in this region of the Oakover Basin is typically associated with elevated iron contents that are commonly equal to or may locally exceed manganese concentrations.
At the Blue Valley (E46/1069-I) prospect, manganese and iron enrichment is encountered across two 500m to 650m long NE- and E-trending zones of prominent surface enrichment.
Significant manganese intervals from previous reverse circulation (RC) drilling at Blue Valley include:
- 6m @ 21.4% Mn from 5m (BLVR006)
- 9m @ 14.3% Mn from 26m (BLVR022)
- 11m @ 9.7% Mn from 22m (BLVR024)
- 6m @ 17.8% Mn from 24m (BLVR028)
In addition to manganese, significant iron mineralisation has also been encountered in drilling at Blue Valley, including:
- 8m @ 57.6% Fe from 27m (BLVR004)
- 9m @ 52.4% Fe from 52m (BLVR012)
- 13m @ 58.2% Fe from 1m (BLVR018)
- 7m @ 56.5% Fe from 17m (BLVR024)
- 19m @ 62.1% Fe from 10m (BLVR029)
