Dolomite aggregate deposit crystal brook

Two deposits, comprising gently dipping dolomitic sediments of the skillogalee dolomite, were located during a reconnaissance for construction materials for the crystal brook bypass. The southern deposit, 4 km north east of crystal brook, was subsequently chosen for detailed evaluation. Two diamond drillholes, totalling 78.35 M, were drilled, and a quarry to yield 132,000 m**3 of useable stone in situ has been outlined. This stone is interbedded with 31,500 m**3 of shaly material and overlain by 29,500 m**3 of overburden, some of which may be suitable for subbase.
