• QBS has secured a 10 ha site to develop the QBS Brine Management Complex (QBMC)
• Strategic site located in the heart of the CSG industry with proximity to key regional infrastructure
• QBMC planned to process at least half of all brine produced by the CSG industry in Queensland

Parkway Corporate Limited ('Parkway') is pleased to announce its wholly owned subsidiary Queensland Brine Solutions (QBS) has secured a highly strategic 10 hectare (ha) site to locate the planned QBS Brine Management Complex (QBMC). The QBMC has been designed to permanently address the large-scale and long-term waste brine management related challenges associated with coal seam gas (CSG) production in Queensland, by leveraging proprietary Parkway technologies to convert problematic waste brine into green chemicals. The secured site is strategically located in proximity to the majority of upstream CSG projects with significant onsite wastewater and brine inventories, as well as significant existing electrical infrastructure and major regional roads. Since releasing the QBS Master Plan in 2023, Parkway has systematically identified, evaluated and shortlisted over 30 potential sites, with the secured site representing the most suitable location to develop critical brine processing infrastructure. The planned QBMC project is now anticipated to not only process waste brine from upstream CSG operations but also incorporate the downstream processing (electrochemical synthesis function), as part of a single, highly integrated industrial plant, to be developed in multiple stages. At full-scale development, the QBMC would provide a transformational industry-wide solution based on best available technology (BAT) to an intractable issue that has challenged the CSG industry for many years. Parkway expects, upon receiving development approval, the QBMC project will be the only shovel-ready specialised brine processing facility suitable for providing permanent and compliant brine management services for the CSG industry in Australia. QBS is engaged in strategic collaboration related discussions with several CSG industry participants, as well as major chemical industry incumbents, to explore potential investment, co-development and offtake opportunities to leverage the strategic advantages of the QBMC project.

Parkway currently anticipates that project execution could potentially commence as early as mid-2026, however, this timeline is preliminary in nature at this early stage of project development and is likely to be extended.
