A silica sand mining company that has set its sights on 50 hectares of land in the Philippi Horticultural Area (PHA) in Cape Town is appealing against the decision by the Department of Water and Sanitation (DWS) to refuse it a water use licence.
Keysource Minerals is owned by Ardagh Glass Packaging (formerly Consol Glass), the largest glass manufacturer in sub-Saharan Africa. It produces glass for big food and beverage companies such as Coca-Cola, Distell and Heineken. The company says it is running out of silica reserves at its current mine in Athlone.
But the PHA Food & Farming Campaign says in its comments on the water use licence application that mining will cause a “significant and unacceptable impact” on the environment, the Cape Flats Aquifer, and the surrounding farmlands. The campaign says mining the area is not in the public interest, and will affect food security in Cape Town.
“The PHA is a drought proof farmland, the value of which has become incrementally more clear in the face of the role it must play in offsetting the worst effects of climate change,” the PHA Campaign commented.
Reasons provided by the DWS for refusing the licence include: the lack of a compensation plan for the impact on the wetland; the impact on nearby Zeekoevlei; the loss of habitat and biodiversity; the effect of increased stormwater runoff on the nearby wetlands; and the impact on recharging of the Cape Flats Aquifer.
Keysource Minerals provided 12 grounds of appeal to the Water Tribunal. The company already holds a mining right and environmental authorisation.
The company denied that its proposed water uses constituted an unacceptable risk to Zeekoevlei, bird species or surrounding wetlands. Keysource said the DWS had failed to consider the “negative socio-economic impact if the water use licence is refused” The company said the mine would supply silica both for glass production and for water purification systems, for example in the wine industry. Keysource said the mining area is “one of the last remaining high-grade silica deposits in South Africa” and not opening the mine would have an impact on jobs.
In its papers, the company says its Athlone mine, which provides all the sand for its Bellville glass plant, is reaching the end of its life, and reserves will be depleted by 2025.
Paul Curnow, CEO of Ardagh Glass Packaging Africa, told GroundUp: “there are no alternative silica sources available”.
“A lack of sand supply in the Cape would result in glass production reducing and eventually stopping completely in the Western Cape,” said Curnow.
He said industries which employ thousands of people are dependent on the development of the new mine.
Curnow said extensive environmental impact assessments showed “no damage” would be done to the aquifer.
“We are sensitive to the fact that compromises need to be found and believe that a solution could be reached to allow our industry and others to continue to operate in the region, while protecting the value of the PHA,” he said.
The DWS confirmed that the matter is set down for hearing by the Water Tribunal for 15 to 17 April 2024.
