Lake Rebecca Gold Project
Bulletin’s Lake Rebecca Project is 150km east of Kalgoorlie and immediately along strike of a >1 million ounce gold deposit.
Bulletin’s Ravensthorpe project overlies the Annabelle volcanic sequence and pegmatites which also host the Mt Cattlin Lithium mine and processing plant, 12km to the east. The 57km2 tenement hosts several pegmatite outcrops with lepidolite and spodumene. Previous work identified a series of outcropping pegmatites and costean sampling of one of the outcropping lepidolite-spodumene mineralised pegmatites returned a result of 10m @ 1.1 %Li2O including 1m @ 2.91 %Li2O. A preliminary drill program of this single pegmatite did not show adequate encouragement and the area was subsequently relinquished due to low lithium prices at the time. (refer ASX: Lithium Australia (LIT) releases dated 26 May 2017 and 1 September 2017).
Bulletin believes strong opportunity exists to discovery economic quantities of mineralisation. Other known outcropping pegmatites remain to be tested and the potential under shallow cover is considered high.
Two pegmatite trends are apparent within the host rock Annabelle Volcanics, the same rocks that host the Mt Cattlin lithium pegmatites. Rock chips of outcropping spodumene and amblygonite have returned grades up to 8.21 %Li2O over a 4km trend along the Eastern pegmatite trend that remains open to the north.
Drilling of these spodumene bearing pegmatites is planned to commence immediately upon environmental approvals.
