Rigorous Metallurgical Testwork At Abercromby Confirms High Gold Recoveries Via Conventional Milling (Average c.95%)

West Australian gold explorer BMG Resources Limited (ASX: BMG) (BMG or the Company) is pleased to report that metallurgical test work conducted on Abercromby core samples have confirmed its free milling status and therefore amenability to conventional carbon-in-leach (CIL) processing, with high gold recoveries achieved.


Highlights:

  • Rigorous metallurgical test work undertaken on mineralised Abercromby core confirms free milling ore
  • High overall gold recoveries (93% to 95% after 48 hours, with majority of gold leaching in first 8 hours) and low residue grades
  • Gravity recoverable gold component demonstrated at between 34% and 41%.
  • Low reagent consumption*
  • Composites were representative fresh rock samples (ie free of the influence of weathering)
  • A typical gravity/cyanide flowsheet process as per conventional CIL milling processes was used
The study was conducted on drill core samples representative of fresh Abercromby mineralisation and results are consistent with, and exceed those from previous, metallurgical test work undertaken at Abercromby – refer ASX announcement on 19 April 2021 “High Gold Recoveries (Average 90%) from Metallurgical Testwork of Abercromby Drill Samples”.

This latest testwork was completed by Perth based Extreme Metallurgy and reviewed by GR Engineering Services, which has been retained by BMG to advise on project development for Abercromby.

BMG Managing Director Bruce McCracken said:

“These excellent results are in line with our expectations from high level test work undertaken previously and represent another important step in our progression of the Abercromby Gold Project.

“This second study has reinforced the highly recoverable character of Abercromby gold mineralisation using a conventional gravity/cyanidation flowsheet, and extrapolation of these results implies high gold recoveries for the entire deposit.

“Free milling ore with high gold recoveries and low reagent consumption will significantly bolster project economics at Abercromby where BMG is targeting a maiden Resource at the Capital deposit.”

TECHNICAL DISCUSSION

Test work was conducted on two 50kg, quarter core composites from BMG’s Abercromby Project, and

followed a typical gravity/cyanidation flowsheet, one that is ubiquitous to most mills in WA.

Samples were selected by BMG’s geological team, comprising intervals of fresh, competent, mineralised core, interpreted to be representative of the greater mineralised system and located within the main mineralised portion of the deposit.

Mineralisation is characterised by silica, pyrite, carbonate altered basalt and dolerite, punctuated by quartz and quartz carbonate stockwork veins.

The location of the composites is shown in Figure 1 below; specific details of the drill hole locations are outlined in Schedule 1.

Head assays for the two composite samples were 1.35g/t and 1.87g/t respectively, with low silver content and low levels of deleterious elements of Copper and Arsenic.

Gravity and Cyanidation Testwork

Both samples were tested via typical gravity gold recovery followed by cyanidation by Metallurgy Laboratories in Welshpool.

Both composites achieved high gold recoveries of 93.00% and 94.94% for composite 1 and 2 respectively, each with low gold in tails.

Western Australia Allocates AU$14 Million to Improving Environmental Approval Process

Western Australia's governmentsaid on Monday (November 11) that it is allotting AU$14 million to support the employment of additional staff at the Environmental Protection Authority (EPA) and the Office of the Appeals.

The boost comes in response to the Vogel-McFerran Review commissioned by the government in 2023. It recommended various steps to speed up the state's environmental approval system and secure major projects.

According to the government, employing additional staff will help address existing backlogs and provide faster decisions “without impacting the high standard for protecting WA's unique environment.”
