Eastman PGE Project in WA

Peako to begin RC drilling program at Eastman PGE Project in Western Australia

Peako (ASX:PKO) reports that is has received Programme of Work (POW) approval for its upcoming reverse circulation (RC) drilling program at its Eastman PGE Project in the Kimberley region of Western Australia.

The company reports it has completed all groundwork preparations for the 4,500m RC drilling program to commence.

The drill rig is expected to arrive at the Eastman PGE Project in the coming days with drilling to begin in the first week of July.

Peako’s planned 4,500m RC drill program is designed to complete first pass wide spaced testing across the Eastman Intrusion’s 16.5km strike length to define zones with higher grade stratabound PGE-rich mineralisation within the ultramafic complex.

The configuration of the drill program will incorporate multiple wide-spaced drill fences to test PGE endowment of the complete ultramafic stratigraphy.

The drill program also includes a number of targeted drill sections defined from new and historical data including select area with elevated PGE soil and rock indicators at surface.

Additional drill targets include testing of chromite-rich ultramafic layers across the intrusive complex as well as untested soil and rock anomalies, and Versatile Time-Domain Electromagnetic (VTEM) target zones.

Dr David Selley has completed the field component of a tectono-stratigraphic architectural study directed to define a framework for emplacement of the Eastman Intrusion, PGE mineralisation contained within it to assist drill hole targeting.

Results from the study have identified at least three separate ultramafic intrusion horizons that are strongly serpentinised and deformed.

The three horizons are considered to represent three separate intrusive horizons rather than structural repetitions.

Structural assessment of the area predicts a weakly overturned geological sequence that plunges moderately to the south-west.

Moreover, western exposures of the Eastman Intrusion appear to be more thickly developed and less structurally complex than the eastern parts, however widespread cover sequences make surface definition of the intrusion difficult and drilling is required to evaluate further.

Peako’s Eastman Intrusion is a large underexplored intrusive complex that Peako considers prospective for a major PGE resource.

It is located within the Central Zone of the Halls Creek Orogen, where an array of mineralised layered mafic-ultramafic intrusive complexes have been defined with an established PGE mineral endowment.

The Eastman Intrusion is geologically similar to the nearby Panton and Lamboo Intrusions.

It is interpreted to extend along strike for about 16.5km – divided into an Eastern and Western zone by a granite intrusion.

The Eastern Zone extends for some 9.4km with 2.5km under cover, and the Western zone for 7.1km, mostly under cover.
