Siren Gold Limited (ASX: SNG) has engaged Entech Pty Ltd to provide a Mineral Resource Estimate (MRE) for the Alexander River underground gold project at Reefton in the South Island of New Zealand.
Entech is an experienced mining consulting firm based in Perth with over 35 mining and engineering professionals in the disciplines of Mining Engineering, Geology, Geotechnical Engineering and Ventilation design
Siren previously engaged Entech to provide mine planning and technical assistance to design exploration declines for the Alexander River and Big River underground gold projects.
Siren has also engaged GR Engineering Services Limited (GRES) to complete a scoping study (Study) to examine the possibility of establishing a processing plant at the Company’s Reefton Gold project.
GRES will examine the likely optimum treatment route for a processing facility capable of treating the various gold ores historically produced on the Reefton Goldfield. The Study will also identify all optimal locations for the construction of a processing plant including optimal annual throughput based on various underground mines operating along the Reefton field.
Reefton Goldfields Historical Production
The Reefton Goldfield in the South Island of New Zealand was discovered in 1866 and produced 2M oz of gold at an average recovered grade of 16g/t from 84 historic mines.
Most underground mining ceased by 1942, with the famous Blackwater mine closing in 1951, when the shaft failed after producing ~740koz down to 710m below surface.
At the Blackwater mine Federation Mining is currently developing twin declines to allow underground exploration drilling and plan to extract 700koz of gold down to 1,500m below the surface.
Siren holds a large, strategic package of tenements along the under-explored 40km long Reefton and Lyell Goldfields, with permits covering a further 40kms of buried and historically unmined Greenland Group rocks that potentially host the gold mineralisation to the south of the large historic Blackwater mine.
Siren says the Reefton goldfield was originally part of the Lachlan Fold and gold mineralisation at Reefton has many important similarities to the Fosterville mine in Victoria.
Background
The Alexander Riverproject (comprised of Exploration Permit 60446) is located ~26 km southeast of Reefton. The Alexander River project overlays the areas of the historic McVicar Mine which produced 41,089 oz of gold at an average recovered grade of ~26g/t Au before it closed in 1942.
