Background
Siren is a New Zealand focussed gold explorer, with two key projects in the upper South Island at Reefton (Reefton and Lyell goldfields) and Sams Creek (Figure 1).
Western New Zealand was originally part of Gondwana and lay adjacent to eastern Australia until around 80 million ago. The NW of the South Island of New Zealand comprises an area of predominantly early Paleozoic rocks in broad northerly trending belts which terminate at the Alpine Fault (Figure 1). The Paleozoic sequence is divided into the Buller Terrane, Takaka Central and Takaka Eastern Belts.
These belts are interpreted to correspond with the Western, Central and Eastern belts of the Lachlan Fold Belt. The Buller and Western Lachlan belts contain orogenic gold deposits like Bendigo, Ballarat and Fosterville in Australia and the Reefton and Lyell Goldfields in New Zealand. The Eastern Takaka and Eastern Lachlan belts host porphyry-Au and porphyry copper-gold deposits, like Cadia and Ridgeway, respectively.
There are two distinctive sub-types of orogenic gold mineralisation in Victoria. The deeper (6-12kms) mesothermal deposits that formed almost all the significant gold deposits in the Bendigo and Stawell zones and the shallower (<6km) epizonal gold and stibnite deposits in the Melbourne zone and eastern Bendigo zone, including the Fosterville and Costerfield mines. The latter gold mineralising event in Victoria is characterised by arsenopyrite and stibnite associated gold, which is very similar to the Reefton and Lyell mineralisation.
Siren holds a large (1,000km2), strategic package of tenements in the Reefton, Lyell and Sams Creek goldfields (Figures 20 and 21 and Annexure 1).
Siren’s Global Mineral Resource Estimate now stands at 1.27Moz of gold and 8.7kt of antimony for 1.33Moz @ 3.3 g/t AuEq (100% basis) at a 1.5g/t cut-off.

Reefton Gold Project
The Reefton Goldfield was discovered in 1866 and produced ~2Moz of gold at an average recovered grade of 16g/t from 84 historic mines, plus an estimated alluvial gold production of 8Moz. Most underground mining ceased by 1942, with the famous Blackwater mine closing in 1951, when the shaft failed, after producing ~740koz of gold down to 710m below surface.
OceanaGold Limited (OGL) developed an open pit on the historic Globe Progress mine between 2007 and 2015. OGL recovered an additional 700koz at around 2g/t Au, increasing total hard rock production to around 2.7Moz @ 12g/t Au.
Federation Mining Limited (FML) a privately owned company, is currently developing the Snowy River Mine on the Birthday Reef (Figure 2), which historically produced 740koz of gold at an average recovered grade of 14.2g/t. FML plan to mine the Birthday Reef below the historic mine, with an estimated production of 700koz. FML have developed twin 3.2km declines and are currently resource drilling from underground, with the aim of producing around 70koz of gold per annum for 10 years from the end of 2024.

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.
