Tharisa Additional Waste Rock Storage Project
Tharisa Minerals (Pty) Ltd (Tharisa) is an opencast mining operation that produces chrome and platinum group metals (PGM) concentrate. The opencast mine is located on the farms 342 JQ and Elandsdrift 467 JQ near the town of Marikana in the Bojanala District Municipality and Rustenburg Local Municipality, North West Province.
Tharisa holds existing environmental authorisations (EAs) and licenses under the Mineral and Petroleum Resources Development Act, 28 of 2002 (MPRDA), the National Environmental Management Act, 107 of 1998 (NEMA), the National Environmental Management: Waste Act 59 of 2008 (NEM: WA) and the National Water Act, 36 of 1998 (NWA).
Mining is undertaken, in two mining sections, namely the East Mine and West Mine, using conventional open pit truck and shovel methods. Waste rock from the open pit areas is either stockpiled on waste rock dumps (WRD’s) or backfilled into the open pits as part of concurrent rehabilitation.
As part of its on-going mine planning Tharisa has identified the need for additional waste rock and tailings storage on site. In this regard, Tharisa is proposing to:
- extend a previously approved WRD;
- establish WRDs above backfilled portions of the East and West pits; and
- increase in the capacity of existing tailings storage facilities (TSFs) by means of self-raising or other.
The environmental assessment process required, includes an application phase, scoping phase, and an EIA and EMPr phase. SLR Consulting (South Africa) (Pty) Ltd (SLR), an independent firm of environmental consultants, has been appointed by Tharisa to manage the environmental authorisation process.
This BID has been made available for a 14-day comment period on SLR’s website from 12 April to 28 April 2022. It provides an opportunity for Interested and Affected Parties (I&APs) to comment on any aspect of the proposed project and the findings of the EIA process to date.
