Highlights
Background
Siren is a New Zealand focussed gold and antimony explorer, with two key projects in the upper South Island of New Zealand: Reefton (Reefton, Lyell and Paparoa goldfields) and Sams Creek (Figure 1).
The Reefton Goldfield 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 at Reefton 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 2025.
Sams Creek is a gold mineralised porphyry dyke, that extends over 7km and is up to 50m thick. The Sams Creek Dyke (SCD) was discovered in 1974 and has not been historically mined.
