While our two smaller mineral sands prospects have " some Zircon ", our big kahuna ( Beenup ) while a massive resource, is low quality in terms of Zircon ( IMO).
Issues arising from the legacy data , its not JORC compliant, and we have the issue with sulphuric acid.
From the 1990 EPA Bulletin number # 483 ;
Mineral Deposijs proposes to produce 500,000 tonnes of heavy minerals per year. At about 4% heavy
mineral concentration, this would require the mining of about 12 million tonnes of ore. Mineral
Deposits state that in excess of 500 million tonnes of ore exist. This resource would be sufficient to
sustain a 500,0001/yr operation for at least 20 years. The stated intention ~ approvals are received is
for construction to commence in 1991, wtth mining and !rucking beginning in late 1992.
The proposal involves clearing of any remnant vegetation, removal and re-use of topsoil, ripping of
ironstone hardpan, and then dredging of the ore at a rate of 3000 tonnes per hour, 23 hours per day.
The dredge pond would measure 390m x 1000m at the surface and advance about 3.5m per day.
Dredging would therefore cover about 50ha per year. Use of a sufficiently long dredge arm would
permit mining to the fu!! 50m depth of the deposit without the necessity to reduce the water table by
pumping water out of the pond.
So without knowing the managements plans, perhaps we could stop short of the 50 mtr depth and do away without the sulphuric acid issue by default.
Maybe a Ilmenite beneficiation unit thrown in for good measure , to up the return.
