Excellent Gold Recoveries from Metallurgical Testwork at Katanning Gold Project

Highlights:

  • Excellent results from first phase metallurgical test work for the 1.8 Moz Katanning Gold Project (KGP)

  • The test work demonstrates the KGP ore is free milling and amenable to a conventional CIL processing flowsheet

  • New test work highlights exceptional gold recoveries:

    • - Recoveries of coarse gravity gold between 40 - 69%

    • - Preliminary leach extractions demonstrate average total gold recoveries of between 88 - 94% for the

      Central Zone ores at a 75 µm grind and 24 hour leach time. Higher total gold recoveries of 91 - 96% achieved at finer grinds and longer leach times are to be optimized as part of the current test work program

    • - Low cyanide consumption of 0.5-0.7 kg/t

  • Resource upgrade on track for late April 2022 and Prefeasibility Studies (PFS) targeted for completion late Q2 CY2022

Ausgold Limited (ASX: AUC)(Ausgold or the Company) is pleased to provide an update of exploration and development activities at the Company's 100%-owned Katanning Gold Project (KGP).

Ausgold has now completed its planned 30,000m multi-rig drilling campaign which will add Resource ounces. An additional 2,500m of RC and diamond drilling will continue to further extend areas, including targets within the Jinkas underground and exploration targets within the Rifle Range areas.

Metallurgical Test Work Program

Ausgold has completed a comprehensive metallurgical test work program on five composites from 13 diamond drill holes in the Central and Southern Zones. Initial results have been received from ALS Metallurgy under the supervision of an independent metallurgical consultant, and GR Engineering is progressing pre-engineering works based on the test results.

Leach tests have been completed on five composites (refer Table 1). Three of these composites are from the Central Zone (Jinkas and Jinkas South lodes) and the Southern Zone (Dingo deposit). Recoveries from these samples indicate a consistently high gravity component from all samples with recoveries ranging between 40% up to 69% of total gold recovered. Leach test work indicates between 88-94% recoveries based on a 75 micron grind and 24 hour CIL residence time, with a low residue (tail) grade of 0.15g/t gold across the project. With most of the Central Zone ores, which reflect the majority of the current Resource being in the range of 88-94%. At a 53 micron grind and 48 hour residence, overall average gold recovery increases to 91-96%.

Reagent usage was relatively low with less than 0.7 kg of cyanide (NaCN) consumed per tonne of ore on the Central Zones and less than 1kg/t on Southern Zones. Further studies will consider pre-oxidation to further reduce reagent consumption.

Further test work is now underway which will support the Prefeasibility Study, including an additional seven composites which will examine the variability along strike and at higher gold grades to confirm these excellent recoveries. This will provide a robust understanding of the overall physical characteristics of crushing and grinding, as well as gold recoveries and processing costs across the project. A low-grade sample is being tested to confirm recoveries at lower grades and inform the cut-off grade determination for the Prefeasibility Study.

Management Comment

Ausgold Managing Director, Matthew Greentree, commented:

"The new metallurgical test work results have exceeded our expectations and now provide a positive foundation for our view that Katanning can support a meaningful high margin gold-producing operation.

These excellent results include a high gravity component reflecting the coarse-grained gold within the deposit and coupled with the free milling ores and high overall gold recoveries, we have a simple, low risk flowsheet that gives us a high level of confidence on project economics as we work to deliver a Prefeasibility Study by mid year."

Work Programs

At present one RC rig is operating at the KGP drilling in both the Central and Southern Zones, with the results of this drilling to support a Resource upgrade early in Q2 CY2022.

  • Resource Drilling - Ausgold has now completed 30,000m of its RC drilling campaign focusing on high-priority targets in the Central and Southern Zones of the KGP, with a further Resource upgrade planned for April 2022.

  • Rifle Range Drilling - RC drilling has been completed along the eastern edge of the Rifle Range Area targeting the down-dip portions of the Dingo deposit. Further drilling is planned for a low-impact small track-mounted diamond drill rig for the Rifle Range area, further expanding the Resource potential over 2.5km strike length for the Southern Zone.

Prefeasibility Studies (PFS) are rapidly advancing with results of metallurgical test work expected to be available in early Q2 CY2022 and completion of PFS late in the same quarter.

  • Mine Development Studies - Work is underway to support studies for the Katanning Gold Project, which will assess potential mine development scenarios for the KGP. GR Engineering has been engaged to lead the engineering studies and the Company anticipates that a Prefeasibility Study for the initial stage of development at the KGP will be completed in Q2 2022.

  • Geotechnical, hydrogeology and metallurgical drilling is planned in the Central Zone and Dingo Resource areas to support future open pit and underground mining studies. This follows recent diamond drilling to collect geotechnical data, supported by down-hole televiewer programs in RC and diamond holes. Additional diamond drill holes will follow to collect samples for metallurgical optimisation testwork. Furthermore, additional groundwater monitoring wells will be installed to complement existing groundwater monitoring data.

  • Metallurgical test work - ongoing test work is now focused on optimisation of comminution process flow sheets and leach test work on fresh composites. Initial waste rock and tailings characterisation test work continues.

  • Community and environmental studies - stakeholder engagement is underway along with development of the approvals pathway.
