Second High Grade Lithium Trend Confirmed | |||
Ravensthorpe Lithium Project | |||
Highlights | |||
only | • A second high grade lithium pegmatite trend (Western Pegmatite | ||
Trend) has been confirmed parallel to the high grade spodumene | |||
bearing Eastern Pegmatite Trend (refer ASX BNR announcement 17 Feb | |||
2022) | |||
• The lepidolite bearing Western Pegmatite Trend represents an | |||
use | |||
excellent additional second leg to the Ravensthorpe Lithium | |||
Project | |||
• This is the first sampling program that BNR has conducted at the | |||
Horseshoe pegmatite which is part of this Western Pegmatite | |||
Trend | |||
• Horseshoe pegmatite returned rock chip assays up to 4.50% Li2O | |||
personal | with an average assay of 3.1% Li2O, 0.8% Rb and 0.16% Cs along | ||
a 50m long outcropping lepidolite mineralised zone | |||
• Rock chip assays at Horseshoe pegmatite include: | |||
o | 4.50% Li2O | ||

o | 2.39% Li2O | ||
• Additional known lepidolite zones at Horseshoe pegmatite | |||
remain to be tested | |||
• Bulletin will advance exploration of both the Western Pegmatite | |||
Trend as well as the Eastern Pegmatite Trend where exceptional | |||
spodumene results were recently reported | |||

Bulletin Resources Limited ("Bulletin", "BNR") is pleased to provide laboratory results from recent rock-chip sampling conducted at the Western Pegmatite Trend at its Ravensthorpe Lithium project. The project is located only 12km southwest and along strike of Allkem Limited's (ASX: AKE) Mt Cattlin Lithium Mine.
Western Pegmatite Trend
An initial, limited rock-chip sampling program at regular 10m intervals along the strike of a 1m wide and 50m long, lepidolite rich, outcrop in the southern portion of the Horseshoe pegmatite returned lithium grades up to 4.50% Li2O with an average grade of 3.1% Li2O, 0.8% Rb and 0.16% Cs (Figures 1 - 3).
Laboratory results of the six rock chip samples at Horseshoe pegmatite are:
- 4.50% Li2O o 3.09% Li2O o 2.85% Li2O o 2.79% Li2O o 2.68% Li2O o 2.39% Li2O

For personal use only
Bulletin CEO, Mr Mark Csar said, "following on from the recently reported exceptional spodumene and amblygonite lithium rock chip assays at Big pegmatite within the Eastern Pegmatite Trend, it is extremely pleasing to report high grade lithium assays within the Western Pegmatite Trend. We now have a great opportunity to progress two lithium plays only a few kms apart in this incredibly prospective area with an operating lithium processing plant only 12km away."
Further work
The previous explorer, Lithium Australia, mapped extensions to the lepidolite zone sampled in this recent mapping program at the Horseshoe pegmatite and these extensions will be sampled to gain a better understanding of the potential of the area (Figure 2). While no spodumene has been mapped as of yet in this part of the Horseshoe pegmatite, the remainder of Horseshoe as well as other outcropping pegmatites in the Western Pegmatite Trend will be investigated to evaluate their potential economic value.
A full set of results is provided in Appendix 1.
