• Follow-up rock chip sampling at Bravo Cluster and Charlie Pegmatite has returned the highest-grade results thus far, up to 3.36% Li2O at surface
• Pegmatites in this area now interpreted to be significantly larger than previously thought
• Located within 200m of the previously announced thick pegmatite intersections in WD4133 and WD5301
• Drill planning underway to test the high-grade lithium outcropping pegmatites at depth and to twin WD4133 and WD5301
• Soil sample collection phase was very successful and completed on a 200m by 50m grid pattern with HXRF analyses underway Figure 1. Photo of the outcrop at Charlie Pegmatite, which has returned up to 3.36% Li2O
Estrella Resources Limited (ASX: ESR) (Estrella or the Company) is pleased to inform shareholders of the follow-up rock chip sampling at Bravo Cluster and Charlie Pegmatite, Atomic Three prospect area.
The sampling has returned the highest-grade results on the MELP so far, and is part of systematic and ongoing mapping, rock chip sampling, and soil sampling programs.
BRAVO CLUSTER
The Bravo Cluster is located approximately 600m NNW of the 132N nickel mine, or 250m SW of the Alpha Pegmatite targeted by the first phase of drilling on the MELP. Six rock chip samples have been collected at Bravo Cluster, half of which returned over 1.5% Li2O, with a peak value of 1.68% Li2O. Detailed mapping has now been completed on the prospect.
This has shown that Bravo could be a single pegmatite, rather than a cluster of smaller bodies, and the pegmatite could be significantly larger than previously interpreted. The numerous small rubbly outcrops at the prospect are now interpreted to represent a single pegmatite body in a deeply weathered and poorly exposed environment.
CHARLIE PEGMATITE The Charlie Pegmatite is located approximately 200m east of the Bravo Cluster. It is less than 200m from the broad historic pegmatite intersection in holes WD4133 and WD5301, which will be targeted by twin holes in an upcoming drill program, after historic diamond core was unable to be located within core storage locations.
Detailed mapping has been completed and nine follow-up rock chip samples have now been collected from the prospect. The size of the pegmatite is now interpreted to be larger than previously thought, and it may possibly be connected to or be of the same pegmatite as the Bravo Cluster.
Sampling at the Charlie Pegmatite included the following very high-grade lithium results.
Follow-up drilling will be conducted as soon as practicable in the Bravo and Charlie areas to determine if the new interpretations are correct, to determine if the pegmatites are related to each other, or are connected, and to generate a JORC2012 mineral resource estimate.
A soil sampling program was recently completed over the Atomic Three prospect area, which includes the Bravo Cluster and Charlie Pegmatite. 458 samples were collected on a 200m by 50m grid pattern. The aim of the soil sampling program is to determine if soil sampling could be an effective technique for identifying blind lithium bearing pegmatites with no visible surface expression, and if so, determine if there are any such pegmatites in the Atomic Three area.
Samples from the program have been transported to Kalgoorlie and are in storage while the Company awaits the arrival of a new handheld XRF unit. When the XRF unit arrives, the soil samples will be analysed as soon as practicable.
