Angas Zinc Mine – Quarterly Environment Report
No non-compliances against lease Conditions for Quarter 1, 2018
Correction to QER
No non-compliance against PM10 Outcome Measurable Criteria
Review: “PM10 dust levels collected from the HiVol PM10 sampler located at the visitors viewing area (Figure 44 - same location as the HiVol sampler), will be sampled over a 24hour period every six days as per AS, 3580.9.3:2003 standards. Data will demonstrate compliance with NEPM 1998 criteria of <50 micrograms/m3 per 24 hour period with <5 days exceedances per year.”
Terramin still conducted investigation as to why

Hydrostor A-CAES System Basics
Terramin Zinc Mine A-CAES System
Benefits for Australia
Fossil Plant Replacement
• Repurpose decommissioned thermal plants and defer remediation costs
• Re-use of existing interconnection and infrastructure• Synchronous generation for reliability, without emissions
Transmission Deferral
• Non-wires alternatives to defer grid network investment• Alleviates grid congestion during peak periods• Locatable reliable power for critical areas and infrastructure
Renewable Integration
• Provide dispatchable, base loaded renewables• Optimize solar/wind project economics through time-shifting • Reduce curtailment
Mines / Large Industrial
• Ability to eliminate fuel costs & logistics (off-grid)• Improve reliability and reduce electricity grid charges (on-grid)• Re-use legacy mining infrastructure
