Atomic analysis proves AXE’s graphite ‘near-perfect’

Published at Apr 6, 2018, in Mining

Archer Exploration Limited (ASX:AXE) has today announced the findings of technical analysis undertaken at the world-class Australian Centre for Microscopy & Microanalysis at The University of Sydney. The analysis focused on the structural and physical properties of graphite samples sourced from its Campoona graphite deposit, via viewing individual carbon atoms at an atomic scale.

The analysis found that the intrinsic physical properties of AXE’s graphite is suitable for use in batteries and the production of graphene. Further, the high quality of the graphite is maintained even after mechanical and chemical processing.

The results confirmed the structure of the Campoona graphite lattice closely matches the ideal theoretical crystalline structure for graphite, with samples consistently showing a high degree of crystallinity clearly visible in the electron microscope images.

The method involved nano-scale and atomic-scale analysis of representative, processed samples of AXE graphite materials extracted from Campoona, using various techniques such as JEOL3000F Transmission Electron Microscope. A key objective of the analysis was to investigate the “’structural integrity and quality of the graphite samples that had undergone mechanical and chemical treatment to yield 99%+ total graphitic content”, according to the company.

It’s worth noting that AXE is an early stage play and investors should seek professional financial advice if considering this company for their portfolio.

The microscopic images demonstrated, at an atomic level, the high quality of AXE’s graphite, with minimal defects; this is critical for AXE considering it is important for battery applications and high-quality graphene production using graphitic feedstocks.

Importantly, AXE can now utilise the positive findings in discussions with potential off-take partners as well as end users.

Archer CEO Mohammad Choucair commented: “This is an exciting development for Archer and it confirms our view that we are capable of producing high quality graphite from our Campoona deposit. These excellent results will greatly assist the ability for us to market our material to potential customers and end users.

“Together with atomic-scale imaging of our graphite, we also performed a number of microscopic, spectroscopic and physical property technical analyses to capture a complete picture of the material quality.

“The ability to obtain atom-level insights using Archer’s in-house expertise is unique and sets Archer apart from other companies. This technical data is now available to potential offtake partners and customers ready to integrate our materials in high-volume applications down-stream.

“At the most fundamental level, this work shows the graphite sourced from Campoona, after mechanical and chemical processing, retains its high structural integrity. We are confident in our capability to produce high quality graphite which is also suitable for high-value graphene production.”
