Siren Gold Limited (ASX: SNG) has mobilised a third diamond rig to accelerate drilling at its Reefton Reefton Goldfield in New Zealand.
Two rigs now drilling at Alexander River and one at Big River.
A CS1500 capable of drilling HQ core to 800m and NQ core to 1,200m has been mobilised to Pad 30 at Alexander River.
The CS1500 will target the McVicar West shoot down plunge from drillhole AX84, which intersected significant visible gold, and the newly discovered Bull West shoot that was intersected by AX68a.
The second diamond rig (CS1000) will continue targeting the extension of the Bull and McVicar East shoots further down plunge.
The LF70 diamond rig was relocated to Big River and has commenced drilling. A total of 7,000m of diamond drilling is planned at Big River to target the six shoots at around 400m below surface.
Drilling commenced at Big River in 2011 when OceanaGold Limited (OGL) drilled 19 diamond holes for a total of 4,106m.
Siren commenced diamond drilling at Big River in October 2020, with 16 holes completed for a total of 2,743m. Drilling was stopped temporarily in April 2021, so that the rig could be used at Alexander River to help complete the drill out for the maiden inferred resource, due in April 2022.
OGL’s drilling focused on the SE side of the Big River mine, targeting 100 to 200m below the surface.
Siren targeted Shoot 4 and extended the shoot to around 400m below the surface. BR35, which is the deepest hole drilled at Big River to date, intersected 5.9m @ 4.1g/t Au. This hole intersected approximately 100m below mine Level 7, which was the deepest level Shoot 4 was mined to, before the mine closed in 1942 during the Second World War. Several of the drillholes intersected a second mineralised structure (4b) 5-10m below.
Siren has estimated an Exploration Target of between 100koz and 125koz at a gold grade between 7-9g/t Au for Shoot 4.
With additional drilling similar exploration targets could potentially be estimated on the other shoots.
The company considers Big River has upside potential of 250koz to 500koz.
