Ann: 3D Resources To Process Mullock On Site At Adelong, page-2

3D Resources progresses plans to process mullock dumps to generate early cash flow
 Adelong plant upgrade to enable on site processing of mullock
As previously announced on 25th June 2020, the mullock dumps scattered throughout the Adelong gold project
(see Figure 1) have had a substantial amount of work carried out on them with several programs of sampling and
bulk sampling having already been completed.
Various historic estimates of quantities of waste dump material, and the grades contained within, have been
made with the latest on record in 2006 showing a historical estimate of approximately 119,400 tonnes averaging
1.54 g/t gold (approx. 5,900 oz)1
Since that time, around 10,000 tonnes of mullock close to the Adelong Plant was used in commissioning of the
plant, with these dumps producing results at the estimated average grades. While the majority of this work predated JORC (2004), a review of this work showed the survey methodology and sampling techniques were done to
a reasonable standard.
Bulk testing has also indicated that these dumps are amenable to upgrading through simple screening to grades
of +2 g/t Au. Further work will need to be undertaken before these waste dumps can be reported as a JORC
Resource.
Mullock Processing Consideration
Options identified for generating near term cash flow from the mullock dumps include the shipping of a highgrade portion of the material for treatment to a traditional and unutilised carbon-in-leach (CIL) processing facility
located approximately 200km from the Adelong gold project.
Investigations undertaken included a site visit to the processing facility and the preparation of cost estimates on
two options for processing the mullock at Adelong for delivery to this plant. Both options showed a positive
return however, the assessment of the CIL processing plant itself highlighted some limitations as to the available
capacity in the Tailings Storage Facility (TSF) and a potentially lengthy process to obtain approvals to expand that
facility.
1 Formed part of Adelong Open Cut Scoping study 18 April 2006 by Metcalfe Mineral Management Services Pty Ltd
(some low grade dumps excluded). These historical estimates are not reported as JORC Compliant Resources and a
competent person has not done sufficient work to report these as a JORC Resource, and it is uncertain that
following further evaluation that the historical estimate will be able to be quoted as a Mineral Resource in
accordance with the JORC Code.
