Bird in Hand update Approved drilling programme for collecting metallurgical and
geotechnical engineering data to feed into mine design geotechnical characterisation and groundwater modelling to support mine
design and metallurgical testing to provide recoveries, Angas plant modification and tailings classification
Next stage is Retention Lease
Landscape design underway to inform revegetation planning for Winter 2016
Terramin’s intention is to develop the Bird in Hand Gold Project and process ore at Angas site
Provides 60 jobs at Woodside and 40 at Strathalbyn
Current scope is for 12 loads of ore delivered daily to Angas site5
