Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report an updated JORC compliant (2012 Edition) Mineral Resource Estimate (MRE) for the 100%-owned Feysville Gold Project (Feysville), located 14km south of Kalgoorlie in Western Australia (refer to Figure 2 below).
HIGHLIGHTS:
- Updated JORC 2012 Mineral Resource Estimate (MRE) of 5.0Mt at 1.2g/t Au for 196koz of contained gold completed for the 100%-owned Feysville Gold Project (Feysville), located 14km south of Kalgoorlie in WA (Feysville MRE).
- The Feysville MRE includes maiden MREs for both the Kamperman and Rogan Josh deposits, as well as an updated MRE for the Think Big deposit.
- Mineral Resources have been estimated using a 0.39g/t Au lower cut-off and constrained within pit shells derived using a gold price of A$2,500 per ounce (consistent with the price used for the current MRE at the Mandilla Gold Project (Mandilla) reported on 20 July 20231 (Mandilla MRE), noting that, at that time, the spot gold price was considerably less than it is today.
- Mineralisation encompassing the Kamperman and Rogan Josh MREs was discovered at an average cost of approximately $19 per ounce. This compares to Astral’s peer group, members of which are currently trading at enterprise values in the range of $38 to $82 per mineral resource ounce2.
- The oxide and transitional deposits at Rogan Josh and Think Big total 1.6Mt at 1.3g/t Au for 68.2koz of contained gold. Combined with the 2.0Mt at 1.3g/t Au for 83.8koz of contained gold at Kamperman, Astral considers there to be significant potential to increase the production target for the Mandilla Pre-Feasibility Study (Mandilla PFS), with work well underway.
- The Mandilla Scoping Study (Mandilla Scoping Study) reported during September 20233 included processing lower grade material of approximately 4.5Mt of Mandilla ore grading less than 0.70 g/t Au during the first five years of operations. The higher grade Feysville ore is expected to displace this ore, contributing significant economic upside to the Mandilla PFS compared to the Mandilla Scoping Study.
- The Mandilla PFS is likely to incorporate a pit shell design parameter of at least A$2,600 per ounce for mine optimisation. This exceeds the gold price parameter of A$2,500 incorporated in the calculation of Mineral Resources for both Mandilla and Feysville and, therefore, is likely to support a relatively high conversion rate of Mineral Resources into the Mandilla PFS production target.
- Including the Mandilla MRE of 37Mt at 1.1g/t Au for 1.27Moz of contained gold4, Astral’s total gold MRE is now calculated to be 42Mt at 1.1g/t Au for 1.46Moz of contained gold (Group MRE) (refer to Table 10).
Astral Resources’ Managing Director Marc Ducler said: “When we returned to drilling at Feysville in November 2022, we did so with a view to building critical mass to support our flagship Mandilla Gold Project. As our understanding of Feysville increased, we formed the view that the highly-underexplored Feysville tenement package had the potential to contribute several 100,000-ounce open pit opportunities to the broader Mandilla Gold Project as contemplated in the Mandilla Scoping Study3.
“With today’s Feysville MRE announcement, Astral is well on the way to delivering on this potential.
“The Mineral Resource Estimates across both Mandilla and Feysville are now consistently reported within pit shells incorporating a A$2,500 gold price and cut-off grades of 0.39g/t Au.
“While we acknowledge that using a gold price of A$2,500 to constrain the Feysville MRE is too conservative given the current spot gold price exceeds A$4,000, we intend to update the Group MRE using a more appropriate gold price and cost assumptions as the current data becomes available through advancement of the Mandilla PFS. To adjust revenue pricing assumptions prior to gaining certainty over cost assumptions is not considered appropriate.
“Importantly, the maiden Kamperman MRE has yielded a 1.3g/t open pit resource with a 5.9:1 strip ratio. Given our intention is to use a gold price of at least A$2,600 for pit design for the Mandilla PFS, we are very confident that a strong conversion of this resource into the production target will be achieved and, hence, make a material contribution to the economics of the Mandilla PFS.
“It is also important to note that the Kamperman deposit offers further significant growth potential based on the results of the recent 31-hole/3,834 metre reverse circulation (RC) drill program recently completed. These results are not included in the Kamperman MRE; however, one of the reported intercepts – 3 metres at 177g/t Au from 74 metres as part of a broader intersection of 25 metres at 24.3g/t Au from 68 metres in hole FRC3785 – is quite outstanding and suggests there to be scope for considerable upside with further drilling.
“Similarly, the supergene deposits present at both the Think Big and Rogan Josh MREs are also likely to have a very high conversion rate into a production target.
“Astral remains committed to further increasing the Group MRE through extensional drilling, as well as increasing the geological confidence levels – and, hence, MRE categories – through further in-fill drilling. Two rigs are currently on site at Mandilla, a diamond drill (DD) rig and an RC rig, with the RC rig expected to relocate to Kamperman before the Christmas period for further in-fill and extensional drilling.
“Astral expects to report revised MREs for both Mandilla and Feysville in Q1 next year, ahead of the anticipated completion of the Mandilla PFS in Q2 2025.”

Second LiDAR interpretation identifies additional compelling targets at GDM’s Devils Mountain Gold Project
Highlights:
- GDM purchased the Gympie 2023 LiDAR dataset from the QLD Government, totalling 80 km2, covering EPM 26135, which lies directly SE of the historical gold mining town of Kilkivan.
- A comprehensive LiDAR interpretation was undertaken by specialists GeoCloud Analytics. The interpretation indicated a total of 486 potential historical mine workings, including 40 adits, 16 shafts and 430 other prospecting pits. Many of the old workings were not previously known to GDM.
- The new LiDAR results, combined with previous exploration data has significantly enhanced GDM's dataset, used to identify and prioritise gold bearing targets for further follow-up exploration work.
Chief Executive Officer, Justin Haines, commented:
“This second LiDAR dataset for Devils Mountain has allowed GDM to get a more accurate picture of all of the historical gold mining at Kilkivan prospects area. Shafts and adits are good indicators of the presence of significant gold and base metal mineralisation, because of the effort invested in producing those old excavations. The LiDAR results confirm GDM’s strategy of targeting areas of abundant historical workings and applying modern exploration technologies to those targets”.
Devils Mountain Project
GDM’s Devils Mountain Project comprises 5 x EPMs (17685, 26062, 26135, 26709, 28438) located ~30 km northwest of Gympie (see Figure 1). The Project lies in the Palaeozoic Gympie and Wandilla Provinces of the New England Orogen in southeast Queensland.
Devils Mountain is highly prospective for gold and is host to an abundance of mineral occurrences. In addition to gold, the area contains occurrences of copper, silver, lead, zinc, tungsten and mercury, as well as a number of manganese deposits (see Figure 2). It’s geological setting has many similarities to the nearby Gympie goldfield.

LiDAR Survey Data
LiDAR specialists GeoCloud Analytics purchased part of the Gympie 2023 LiDAR dataset from the QLD Government on behalf of GDM, over an 80 km2 area in the western part of the Devils Mountain Project, covering EPM 26135. The resolution of the raw data is 1 m. GeoCloud Analytics reprocessed the point cloud data to yield a 50cm resolution bare earth Digital Terrain Model (DTM).
The LiDAR survey was flown in 2023 with a minimum average density of 10.5 points per square metre with an average flying height of 1933m above ground level. Details of the survey are provided in the JORC Table 1, see Appendix 1.
A number of new LiDAR images were generated by GeoCloud Analytics in order to extract more information about the project. The enhanced 3D datasets and 2D images produced have facilitated detailed interpretations, allowing the identification of historical mine workings, prospecting pits, geological structures, access tracks and other surface features such as drill pads.

Gidji Drilling Delivers More Gold Results
Miramar’s 80%-owned Gidji JV Project (“Gidji” or “the Project) is located approximately 15 kilometres north of Kalgoorlie and surrounded by multiple gold mining and processing operations, including Northern Star Resources Limited’s Kalgoorlie gold operations (Figure 1).
Miramar’s Executive Chairman, Mr Allan Kelly, said the first results from the current programme confirmed and extended the extensive supergene gold footprint discovered in previous drilling.
“The new results increase the footprint of the high-priority Blackfriars target, which shares several similarities to the multi-million-ounce Paddington gold deposit along strike to the north, including its location at the contact between the Boorara Shear Zone and the Black Flag Beds,” he added.
“This is the first systematic drilling at Gidji after a break of almost 3 years whilst, at the same time, the Australian dollar gold price has risen from $2,500/oz to well over $5,000/oz,” Mr Kelly said.
Current and previous drilling has outlined an extensive area of flat-lying supergene gold across multiple targets at Gidji, despite the stripped weathering profile under the Gidji Paleochannel.
The current drilling programme consists of approximately 180 aircore holes and aims to further refine bedrock drill targets under the younger transported paleochannel sediments.
Drilling commenced before Easter, was suspended due to heavy rainfall and recommenced on 6 May.
