Siren Gold Limited (ASX: SNG) has engaged Measured Group to provide a Mineral Resource Estimate (MRE) for the Sam’s Creek underground gold project in the South Island of New Zealand.
Measured was established in 2007 and is a multi-disciplined mining services consultancy, focused on providing geology, mining, engineering and technical services to the resources industry, financial and legal institutions and government agencies.
The company provides consulting services across the mining value chain, including target generation and greenfield exploration, resource economic evaluation, optimisation studies, operational support, due diligence, independent technical reviews and expert reports.
Mineral Resource Estimate
Siren believes there is significant potential at Sam’s Creek for a large underground mining operation. The Sam’s Creek Dyke (SCD) is up to 60m thick, can be traced for over seven km along strike, has a vertical extent of at least one km and is open at depth. Drilling to date has focused on a one km section of the dyke from the Carapace to the Main Zone.
Topography is very steep, with the SDC outcropping from 800m-200m above sea level and it has been intersected in drillholes to -200m. To date around 127 diamond holes have been drilled in this zone.
Golder completed a JORC Main Zone Resource estimate in 2013 for an open pit mining scenario and included large areas of low-grade mineralisation. An Indicated and Inferred Resource of 1Moz @ 1.54g/t Au at a 0.7g/t cut-off was estimated. At a 1.5g/t cut-off the estimate is 588koz @ 2.43g/t Au.
Siren considers that Sam’s Creek is a potential underground mine and believes the model could be improved for an underground mining scenario, by trimming some of the low-grade dyke, and using separate domains for the high-grade mineralization along the fold hinges and lower grade fold limbs.
The 2013 resource estimate does not include the SE Traverse prospect. The SE Traverse is an isolated section of dyke approximately 500m long and 200m wide that is interpreted to be a continuation of the anticline hinge that extends from Main Zone for over 1.5kms and is open at depth. Drillhole intersections in the SE Traverse confirm the continuation of the higher-grade mineralisation in the anticline hinge.
Siren has engaged Measured to complete the MRE that includes the Main Zone, Carapace and SE Traverse based on an underground mining scenario. The MRE is expected to be completed in November 2022.
The deliverables from this MRE will be suitable for the purposes of public reporting to ASX regulations, within JORC (2012) guidelines.
