3D Resources Limited (ASXDD) (3D Resources or the Company) is pleased to provide the following
update as it moves to finalise its strategic review at the Adelong Gold Project situated in Southern
NSW targeting near term gold production. Managing Director of 3D Resources, Mr. Peter Mitchell, commented:
“We continue to approach the Adelong Gold Project as a near term commercial opportunity
to take advantage of the prevailing gold price and the current status as a mine that has been
approved for development and production.
Various options for developing the mine and processing plant have been considered and the
finalisation of these plans continues with a site meeting of 7 engineers completed this week.
In assessing the Company’s plans, it is important to recognise that the current resources
could potentially provide 15 years life of operations at the approved mining rate.” Plant Upgrade
Extensive prior metallurgical test work that had been carried out on Adelong has lead the company
to proceed with additional test work that focused on recovering the vast majority of the gold in a
gravity concentrate from a coarsely ground sample of Adelong Ore. The results of tests on a -1mm
grind size to date have proven to be excellent and while this program of testing continues to the
second stage grind, it is clear from the work done so far that the vast majority of the gold can be
recovered as a viable concentrate from low cost spirals.
There are several key benefits in adopting this approach:
• Reduction of grinding requirements which improves mill throughput. The Company now
plans to install a two stage grinding circuit with a new rod mill designed to grind to 80%
passing -1mm and use the existing ball mill to grind the -1mm tails from the initial spiral
recovery to -350µ for a second stage spiral recovery process. These changes to the
Adelong circuit are expected to lift milled ore delivery to the plant from 6t/hr to 35t/hr.
A third stage crusher is also being considered to assist in this increased capacity.

• Generation of a low-cost process route that can be operated simply by the local
workforce. A video of recent tests has been uploaded on the Company’s website (CLICK HERE - https://bit.ly/3lZPirf) that shows the clean separation of pyrite/gold from
waste using gravity in the -1mm fraction of Adelong Ores.
• Adoption of a coarser grind also assists in waste disposal as the majority of the waste
will take the form of sand that can be stacked not requiring a tailings dam. This material
can potentially be sold as a building product as the spiral process requires no chemicals
that may contaminate this waste product. Processing of Mullock on site
Following the acquisition of the Adelong gold project, the Company undertook a review of an
existing scoping study completed by the former owner to treat the Mullock and/or Underground Ore
from Adelong at a third party cyanide processing plant which was unused at the time. While the
original studies had shown this to be commercial, investigation of other options determined the
opportunity was not the preferred one.
Concurrent work had progressed on the processing options for the upgraded Adelong Plant. The
move away from the use of flotation as the primary method of recovering the gold, towards a low
cost gravity processes that can potentially work well in recovering gold from the Adelong Mullock
material has transformed the potential economics such that the Company now intends to
commission the plant and start production using material from these Mullock dumps, potentially
increasing the profitability substantially
