QUARRY OVERVIEW

Brookby Quarry has been in operation in one form or another since 1940 to service the Auckland region.  Today it is a modern well developed operation that is currently supplying 2.8 million tonnes of Greywacke per annum to the Auckland region.

Brookby Quarry has the capability of producing and supplying circa 6.1 million tonnes per annum utilising the existing onsite plant and equipment that will continue to contribute to Auckland’s rapidly growing urbanisation and resulting infrastructure needs. 

Brookby Quarry produces a wide range of high quality products including asphalt aggregates, concrete aggregates, sealing chip and construction aggregates.  The quarry has existing resource consents that allow sales (trucking movements out of the quarry) of 13.6 million tonnes per year.

Brookby Quarry's total aggregate resource as determined by the International JORC code standards is 301 million tonnes (150 million tonnes of measured resource and 151 million tonnes of indicated resource).  This resource will ensure continuity of high quality aggregate supply into the Auckland market for at least the next 100 years at the current level of demand.
