Mining operation

The Penrice mine produces chemical grade limestone for the Penrice Soda Products Pty Ltd (PSP), Osborne soda ash manufacturing plant.

The mine also produces raw stone for cement manufacture, aggregates, and production material for foundry flux, glass and paver manufacture.

It is estimated that 75.8Mt in situ marble (of all grades) and 11.6Mt waste will be produced from the pit. The volume of product for external sales was 1.27 Mt during 2007/2008 financial year.

Location2.5 km north of Angastonpenrice_blue

Community engagement 

The Penrice Community Consultation Group (PCCG) provides a forum to discuss the operation of the Penrice Mine, considering community views, interests and concerns related to the mine. 

The Penrice Community Consultation Group (PCCG) page on this website includes the following information:

  • notice of PCCG meetings, minutes and presentations given at meetings
  • contact details for registering environmental concerns and complaints.

PIRSA's response to the Aquaterra Report:

Note: from 1 January 2012 the Mineral Resources Division, formerly part of the Department for Primary Industries and Resources South Australia (PIRSA), transitioned to the Department of Manufacturing, Innovation, Trade, Resources and Energy (DMITRE)

  1. The scope of the report was restricted to impacts of the quarry closure and does not include impacts of the quarry deepening over the next 25 years.
  2. Does the deduction of an 'aquifer sink' model for closure take into account the regional east to west groundwater gradient?
  3. PIRSA supports the carrying out of pumping tests if it will improve the accuracy of the analytical model, and assist in the determination of the impacts of quarry deepening over the next 25 years. 

PIRSA has requested the following be provided:

  1. An assessment of the zone of influence and drawdown impacts for deepening of the pit to the proposed level of 224 mAHD (or the maximum level if deeper), over the next 25 years. Within this zone of influence, the impacts on existing wells (irrigation and S&D) and watercourses should be quantified. If the zone of influence intersects the Tertiary sedimentary aquifers to the west, what impacts will that have?
  2. Evidence that the regional east to west groundwater gradient will not change the 'aquifer sink' model to a 'groundwater throughflow' model - maybe a 1-D slice model. 

Golder report 

Assessment of the potential environmental impacts arising from dewatering activity at the Angaston quarryGolder's Goundwater Assessment, Penrice Quarry, 1 October 2008 (.pdf 5Mb)

PIRSA's comments on the Golder Report:Note: from 1 January 2012 the Mineral Resources Division, formerly part of the Department for Primary Industries and Resources South Australia (PIRSA), transitioned to the Department of Manufacturing, Innovation, Trade, Resources and Energy (DMITRE)

Watersearch (2003) noted the presence of a low conductivity schist rock that would severely limit the connectivity between the marble and the Tertiary sedimentary aquifers to the west.

A fall in groundwater level of 50–70m occurs from the fractured rock inthe east, across the quarry site to the sedimentary aquifers to the west.

The report is mainly concerned in determining the impacts of the quarry on a private well. It does however delineate zones of 'most likely' and 'likely' zones of influence at the current pit base of 267 mAHD. The western margin of the 'likely' zone apears to be very close to the Tertiary sedimentary acquifers to the west. 

The report does not address the likely impacts of deepening the Penrice Pit to the proposed level of 224 mAHD.
