Geochemical characterisation & mine waste management assessment

- Mine water management
The Estelle Gold Trend comprises 450 sq. km of unpatented mining claims on State of Alaska Public Lands. Nova Minerals is currently exploring several deposits and identifying prospects along the mineralised corridor.
As the project approaches the Feasibility Study/NI 43-101 stage, initial characterisation of mine wastes and mine water quality is necessary to develop strategies for management that are protective of the environment. Characterisation includes physical characteristics, volume, and chemical / geochemcial characteristics.
- Develop a sampling and analysis programme based on evaluation of site geologic conditions for preliminary geochemical characterisation that meets industry standards
- Go to the site to collect representative samples of ore and waste with site geologists
- Coordinate chemical analysis
- Evaluate results
- Recommendations for additional work
- Established that ore and waste rock is not acid generating
- The only metal of concern identified is arsenic, which is consistent with observations in groundwater and surface water
- Waste and water management will not require extra-ordinary levels of containment and treatment
- Additional characterisation should be performed:
- Other deposits
- Kinetic Field Bin Tests
- Confirmation for less-important metals
SLR is continuing to support Nova Minerals with environmental and engineering evaluations for the Estelle Project.
