15 Hydrology  The hydrology of the Barossa Valley is complex and based on the various aquifers available to licenced users. Sustainability is an important issue for the Barossa long term well being where both vineyard and extractive industry activities continue.  Penrice monitors its water volume usage and reports this as required to the relevant authorities. Penrice has two water licenses, one from the pit for 102 ML/annum from the fractured rock aquifer issued in June 2008 issued at Penrice's request. This volume was based on the data of the last seven years of water extracted, as there was no licence prior to this. The other licence was a direct transfer from the purchase of adjacent land at 25.6 ML/annum and comes from one of the two Barossa floor aquifers and is primarily used for irrigation of Penrice's vineyards.  The licence entitlement is at the low end of the volume required by Penrice to control its activities and product addition being subject to climatic conditions and the ability to become less dependent upon water based solutions where a move to engineering based solutions is preferred.  The current pit plan for the private mine is for the level to be at RL 252, we are mining currently at RL 267. This is just one bench lower than the existing level. Penrice is reviewing the mine plan and pit shell configuration that may enable continuing to mine to a potentially lower level without the need to extract additional overburden but only after the ore reserve is clearly identified and any likely impacts are understood. Penrice has not sought any increase in it water allocation and is restricted by its licence with monitoring of the volume as is required of all licenced users.  Where Penrice has excess water available within its licence requirements, this has at times been offered to several local vineyard operators to supplement their lower water allocation from the Murray River.  Penrice had a hydrology report prepared in October 2008 by Golder Associates based on concerns by one vineyard operator on its impact and this report was made available to the PCCG in More recently, modelling of the operation at mine closure had been done by Aquaterra with a review by DWLBC.

16 15  Resurfacing of entrance 1 st stage commenced Wednesday 5 th August, completion Monday 10 th  Contractor employed full time from July through to September 2009 to manage the entrance and exit of the Mine. Specific responsibilities to include: oEnsure adherence to tarping oWash down the concrete slab between the truck wash and the cattle grid oHire an additional Streetsweeper based at our site for this period for entrance, sweeping as necessary. Two sweepers in action during resurfacing work. oManage the silt traps at exit oManage the screenings on the entrance and exit oWash down the entrance and exit  Envirosweep to continue on current sweeping regime.  Silt traps constructed front entrance  Councils drains cleaned by Penrice Drag Out and Front Road Upgrade

17 16  The Truck Wash upgrade commenced 3 rd August with completion estimated end August. oNew 7 metre centre bar with sprays oNew jets and spinner heads throughout the wash oImproved filtration system delivering cleaner recycled water oPump upgrade to supply a greater volume of recycled water oIncrease the recycle water tank capacity to cope with the volume of traffic oRedirect the current pump to become the reclaim pump oInstall a PLC control unity oImprove signage oInstall red and green light system to instruct drivers on most efficient wash  Resurfacing the road from the Truck Wash to the new weighbridge to be completed by October Drag Out and Front Road Upgrade
