CONCLUSIONS AND RECOMNENDATIONS 1. 2 Present domestic water requj :ments for the project total 4.0 litres p-!:' second based on hou~ing the majority of mine po'?'(sonnel in s . ngle mens I quarters~ 'This allows for sc~me standby capilcity. Adequate tank storage will need v..} be pruvided to meet short term peak c.emand. Process water requireillents can be provided from a conjunctive surface - Groundwater scheme L~corporated within the tailings recovery system~ This will involve construction of a process water reservoir. In years ()f median rainfall, catchment and storage of surface water will provide the process requirements. For the 1 in 5 year dry conditi.on an annual process water defi::::it of 196 ml 1S .:lnticipatpd. Groundwater supplies of lOi/sec will be :0quired to meet tile process water deficit. 3. Exploration has located t ..... o areas capabl e of providing a muJor part of the ')tal water requirements~ The areas are situated '",i thin 5 km of the mine site ~ AREA 2 is earmarked to provide process vlater, based 0:1 wntcr quality criteria. Supplies cf six litres ~~r second h .... ve been estdblished on the bnsis of t!sing 2 existlilg DTW bO!'es and 3 new bores. There is score for dev-elo~}in<.j d further 7 t("~ 8 l/sC'c of w;lter by extension of the cxist1.ng bar-efield along strike~ AREA 3 will provide for domestic rcquir~ments. Five b("lres have been 8stablished, with a combined c<J.pacity of G l/sec. Stife yield from the area is currently assessed at 5 lisee, pending addition eVdluatio:1. 4. The groundwater system has low ?crmeQbility and stor2ge characteristics, and is dependent on periodic rech .. ""rge to sustain pumping. An effective water managemI' policy will need to be developed 1:"0 ensure the I,<later resources are nut over-exploited. 5. Mine dew<'1te::::::ing requirements an~ assessed as minor and in the main will amount to little more than cont.inuous seepage Usc of boreholes would be limited to situations whc~e major st?:uctural featurr-'s will be intersect.ed at depth and short term l.:luws may disrupt mining activily~ ... -., ..... . , " ........ 54.
