Alien Metals provides Elizabeth Hill Tailings update

Published by
Global Mining Review,


Alien Metals Ltd, a minerals exploration and development company, has provided an update on the company's silver project located at Elizabeth Hill, Western Australia.

As announced on 10 March 2021, Alien entered into an exclusivity agreement over the Elizabeth Hill Silver Tailings Project in Western Australia, with a further 45-day exclusivity period agreed as announced on the 26 May 2021.

As part of its ongoing due diligence, the company commissioned a series of metallurgical and recovery tests on a 200 kg bulk sample taken from across the tailings. Due to the continued high demand for testing done at the Perth laboratories, the company has been granted a further 30-day extension to the exclusivity period to enable this detailed study to be completed and full results interpreted (the extension).

This extension will allow Alien to undertake further assessment over the potential retreatment and recovery of the silver tailings as discussions continue regarding the potential acquisition of the project.

A summary of the test work being carried out by ALS Perth includes homogenising the 200 kg bulk sample to ensure its as representative of the entire tailings as possible, further analysis of the grades of the samples being used, testing the optimum particle size for extraction purposes and several recovery methods to find optimum method of extraction in terms of chemical and economic factors.

Elizabeth Hill Tailing Project

  • Alien has signed an exclusivity agreement with Wombat Resources on the historic tailings on site within the Mining Licence (excluded from the original Elizabeth Hill Silver Project acquisition announced on 4 December 2019).
  • Recent initial sampling by Alien on these tailings have returned very encouraging results.
  • From 84 samples taken from 21 locations an average of 472 g/t (13.3 oz/t) silver (Ag) was returned.
  • Initial recovery test work returned an average of over 90% recovery of the silver.

Bill Brodie Good, CEO and Technical Director of Alien Metals, commented: "We are thankful to the Wombat Resources team for this additional extension to the exclusivity agreement on this project without further cost, and are pleased that they understand the current delays being encountered at the labs due to the overwhelming demand stemming from significant mining activity in Western Australia.

"The ALS laboratory in Perth has commenced a detailed suite of metallurgical and recovery tests on the larger bulk sample we took earlier in the year. This analysis will give us the best understanding of the economics of this project and its potential to generate income for Alien to put back into the ground in exploration dollars."
