Siren Managing Director and CEO, Victor Rajasooriar commented:
“Drilling at Siren’s Auld Creek target within the Reefton Project continues to exceed geological interpretations with higher widths and grades than initially expected. The current MRE from Auld Creek is defined solely from the initial fraternal shoot drilling. Over the coming months we expect the results from the recent drilling targeting the Fraternal & Bonanza Shoots to add significantly to the Auld Creek MRE and consequently Siren’s Global MRE which currently stands at ~1.27Moz at 3.1 g/t Au and 8.7kt Sb @ 1.5%”.1
Background
In 2024, Siren’s strategy at Auld Creek is to drill test all four mineralised shoots (Fraternal, Fraternal North, Bonanza and Bonanza East) identified from soil sampling, surface trenching and diamond drilling carried out over the past 12 months.
The Fraternal and Bonanza west dipping mineralised faults are interpreted to be sub-parallel approximately 100m apart (Figure 1). On the Fraternal Fault at least two mineralised shoots have been identified: Fraternal and Fraternal North, which are interpreted to plunge moderately to the south.
The Bonanza East Fault dips to the east and links between the Fraternal and Bonanza Faults. Diamond drilling by Siren in 2023 confirmed the continuance of the Bonanza East Shoot that was intersected in surface trenches, with ACDDH011 intersecting 5m @ 4.1g/t Au and 7.0% Sb 80m below the surface. The Bonanza East Shoot is interpreted to plunge to the north, with the top and bottom limits constrained by the intersection with the Fraternal and Bonanza mineralisation.
Siren plans to target the Bonanza East, Bonanza and Fraternal North Shoots with the initial drilling over the next few months, with all four shoots having then been tested to around 100m below surface. The second phase of drilling will then target down plunge extensions to the mineralisation.
