"For the last 15 years, Mandalay has successfully produced gold and antimony from its Costerfield mine, with standout periods of exceptional production, especially in the last five years from Youle and Shepherd. Through innovative practices, Mandalay has demonstrated the potential for sustained ongoing reserve replacement. In 2024, the Company's primary focus has been on the continued development of near-mine targets to extend mine life and leverage existing infrastructure.
"Drilling activities near Youle and Shepherd have increased our confidence in immediately surrounding areas that contain pods of high-grade mineralization and are expected to be added to the production schedule.
"Additionally, veins located below the highly profitable

2024 Costerfield Near Mine Focus
During 2024, near mine exploration has focused on building mineral resources and reserves around the immediate mining fronts of Youle and Shepherd, while also testing the significant potential beneath and around the Augusta and
To the north, infill and extensional drilling of Shepherd has provided further certainty of the system whilst extending the potential of the westernmost vein sets. Above Youle, the Kendall system has been historically mined, however recent drilling suggests there is still significant mineralization left undisturbed between the two mining areas.
At the end of 2023, the focus of resource extension testing moved from Brunswick Deeps to
Shepherd and Kendall Extensions
Since the last exploration update (
Within Shepherd, the drilling and subsequent geological reinterpretation has provided important insight including the significance of bedding-parallel laminated quartz faults as grade-controlling features. This dynamic has also been demonstrated during mining and integrated into the geological vein model enabling Mandalay to target further areas of potential upgrades near these interactions.
Much of the extension work at Shepherd has concentrated on delineating the westernmost vein (630) within the set. This has also resulted in the identification of parallel veins to the east and west (Figure 2) including some exceptional antimony intersects.
Highlights from this drilling, all in addition to the holes noted above, include:
- 7.4 g/t gold and 49.1% antimony over 0.44 m (ETW 0.22 m) in PD147;
- 18.3 g/t gold and 26.2% antimony over 2.02 m (ETW 1.15 m) in PD190;
- 15.1 g/t gold and 22.2% antimony over 1.26m (ETW 0.53 m) in PD211;
- 26.7 g/t gold and 22.1% antimony over 0.31m (ETW 0.19 m) in SQ040B1 within 611;
- 108.0 g/t gold and 29.1% antimony over 0.58 m (ETW 0.30 m) in PD151;
- 26.4 g/t gold and 36.7% antimony over 0.21 m (ETW 0.18 m) in PD210 and;
- 19.9 g/t gold and 14.1% antimony over 1.69 m (ETW 0.94 m) in PD172 within 632.
Of note is the high-grade antimony values contained within the intercepts; this drilling has confirmed that the 630 vein in this southern area is consistently antimony-rich in addition to gold, which had been inferred from the results presented in Mandalay's 2023 exploration update (see
Targeted drilling has consolidated the concept of the Deimos Fault acting as a major grade boundary for the Shepherd system, although promising mineralized structures have been intersected below the fault. There are indications that further south-westerly step-outs of the system beyond the 630 vein exist and could be tested from surface.
Further north, extensive mining optimization drilling has taken place with a particular focus on identifying and delineating high-grade splay zones. These interaction zones and linking structures provide an important opportunity for upside due to the potential for very high grades. The following intercepts demonstrate the high tenor that has been identified in these interaction zones:
- 107.0 g/t gold and 0.1% antimony over 0.55 m (ETW 0.40 m) in PD114;
- 48.2 g/t gold and 1.8% antimony over 2.87 m (ETW 2.47 m) in PD132 within 600;
- 547.3 g/t gold and 0.1% antimony over 0.86 m (ETW 0.75 m) in KD907 within 605;
- 73.5 g/t gold and 11.2% antimony over 0.29 m (ETW 0.27 m) in PD140 and;
- 751.7 g/t gold and 1.8% antimony over 0.22 m (ETW 0.21 m) in PD142 within 610.
In the Kendall zone, drilling aimed to delineate northern and up-dip continuations of the veins initially developed in 2018 when the Youle area was first accessed by
The Kendall area contains many sub-parallel, vertical veins that occupy an approximately 80m wide zone of cleavage development within the broad hinge of the main Costerfield Anticline. Individual veins are influenced by bedding-parallel laminated quartz faults, where they often are seen to step westward along the fault for several metres. Additionally, a north-west trending fold overprint tends to control high-grade shoots within individual veins, which altogether requires close-spaced drilling to fully understand the system.
Workers in the historic Costerfield mine during the mid-1930s mined the Kendall set of veins down to 8 Level (approximately 930RL). They attempted to find new ore panels to the north and west of the mine with a short campaign of diamond drilling, but had limited success. The company at the time was mainly concerned with finding ore at the current level of mining and had little appetite for continuing vertical development or completing the 9 Level crosscut. As shown in Figure 5, the Kendall system dipped below the area of interest (both to the west and north) and remained untested.
The drilling covered in this release has significantly upgraded the "580" vein of the Kendall area up to the historic 8 Level, and has increased the endowment of the 580 vein with the following high-grade intercepts:
- 82.6 g/t gold and 45.0% antimony over 0.20 m (ETW 0.08 m) in BC394;
- 54.7 g/t gold and 63.5% antimony over 0.60 m (ETW 0.25 m) in BC395; and
- 38.0 g/t gold and 35.7% antimony over 1.00m (ETW 0.54 m) in BC399.
This area is readily accessible for mining with minimal capital development required, and has considerable scope for further additions. Upcoming drilling will investigate the Kendall vein set up to the boundary of the Whitelaw Fault footwall, and also extend knowledge north of the current resource boundary.
Cuffley Extension Testing
Late in 2023, drillhole AD200 intersected high-grade mineralization in a previously untested area below and south of the previously mined
AD213 intersected a gold-rich quartz vein approximately 20m east of the main Cuffley Deeps panel (550.0 g/t gold over 0.15 m (ETW 0.12 m)). Follow-up drilling is underway to determine the continuity and extent of this previously unknown mineralization.
The understanding of prospectivity at the northern end of the
Drillhole TP021 met with success intercepting 4.0 g/t gold and 20.2% antimony over 0.45 m (ETW 0.34 m). Simultaneously, the Cuffley-Brunswick Gap program commenced, drilling across the Costerfield corridor from the east to test a sparsely drilled area north of the
These two intercepts are directly along strike of
Forward Focus of Near Mine Exploration
Given the recent exciting results described above, Cuffley Deeps will remain the primary focus of near mine exploration. Drilling will also continue on the promising northern continuation of the Cuffley System as well as other ongoing targeting of the Brunswick north extension area a potential additional line of veining approximately 300 m to the east of the central corridor.
Regional drilling also continues on depth testing the satellite deposits of
Drilling and Assaying
All diamond drill core was logged and sampled by Costerfield geologists or contracted geologists with significant industry experience who worked under Costerfield geologist's oversight. All samples were sent to On Site Laboratory Services (OSLS) in Bendigo,

About
Mandalay's mission is to create shareholder value through the profitable operation and continuing the regional exploration program, at both its Costerfield and Björkdal mines. Currently, the Company's main objectives are to continue mining the high-grade Youle vein at Costerfield, ramping up production from deeper Shepherd veins, both of which will continue to supply high-quality ore to the processing plant, and to extend Mineral Reserves. At Björkdal, the Company will continue to produce from the Aurora zone and other higher-grade areas in the coming years, in order to maximize profit margins from the mine.

Notes |
|
|
1. |
The AuEq (gold equivalent) grade is calculated using the following formula: |
|
|
AuEq g per t=Au g per t+Sb% × |
(Sb price per 10kg×Sb processing recovery) |
|
(Au price per g×Au processing recovery) |
|
|
Prices and recoveries used: Au $/oz = 1,900; Sb $/t = 11,700; Au Recovery = 93% and; Sb Recovery = 92% |
|
2. |
LLD signifies an undetectable amount of antimony. Detection limit for the analysis used is 0.01% |
|
3. |
Composites that are not interpreted to be connected to a named vein and are below 1 g/t AuEq when diluted to 1.8m are not considered significant and are not recorded here. |
