Main Street Survey Activities Block 11B/12B South Coast, South Africa

Main Street held Exploration Right 12/3/067 over Block 11B/12B, located off the South Coast of South Africa, roughly between Mossel Bay and Cape St. Francis. Following the discovery of gas-condensate at the Brulpadda and Luiperd wells within Block 11B/12B, the joint venture partners at the time, under the lead of TotalEnergies EP South Africa (TEEPSA), started the associated ESIA process, which included a public participation process conducted in 2022 and 2023.

Following the withdrawal of some joint venture partners in late 2024, Main Street remains as the sole applicant of the EA Application and proposes to initially conduct a downscaled and largely non-intrusive survey campaign along the potential production sites and pipeline routes from the deep-water field areas in Block 11B/12B onto the shelf and into the adjacent Block 9 (Block 9 is held by PetroSA). The findings of this survey will provide essential data that informs the design and layout of the subsea production facilities and associated infrastructure.

The area of interest (AOI) is >65 km offshore in water depths between 100 m and 2 200 m. The proposed surveys include bathymetry, sonar, seafloor sampling, metocean and ROV surveys in a maximum survey area of interest measuring 8 620 km2 within portions of Blocks 11B/12B and 9.

Prior to the commencement of the Proposed Project, an Environmental Authorisation in terms of the Environmental Impact Assessment Regulations, 2014, (GN R 982 of 2014), promulgated under the National Environmental Management Act, 1998 (No. 107 of 1998) from the Department of Mineral and Petroleum Resources (DMPR) is required.

SLR Consulting (South Africa) (Pty) Ltd (SLR), an independent firm of Environmental Assessment Practitioners, has been appointed to manage the environmental authorisation processes.
