Potash – Our major potash project under development at Jansen is tracking to plan. In the March 2023 quarter, we commenced blasting and excavation work at the bottom of the shafts. For the remainder of the 2023 financial year, we will continue to focus on civil and mechanical construction on the surface and underground, as well as equipment procurement and port construction. The feasibility study for Jansen Stage 2 continues to progress and is on track to be completed during the 2024 financial year.

Minerals exploration
Minerals exploration expenditure for the nine months to 31 March 2023 was US$239 million, of which US$196 million was expensed.
BHP has identified a new copper porphyry mineralised system, Ocelot, located 140 km east of Phoenix, Arizona, United States in the Miami-Globe copper district. From 2019 to present, BHP has drilled 12 holes in the project area, totalling 17,748 metres with 10 holes intersecting porphyry copper style mineralisation. Ten of the holes resulted in 12 intervals of significant intercepts with laboratory assay results average copper grades ranging from 0.44 to 0.92 per cent copper. The project remains at an early exploration stage with two holes to be completed from the current exploration drill program and is expected to be completed by May 2023. For further details refer to Appendix 1.
At Oak Dam in South Australia we continue to work in close partnership with traditional owners, and the South Australian government have recently granted environmental approval for the next phase of exploration drilling. The approval permits up to 14 drill rigs, more than double the current approval, an accommodation camp for up to 150 people and core processing facilities. We currently operate 6 drills rigs in the area and expect to increase this to 10 drill rigs by the end of the September 2023 quarter.
Following the execution of the Option Agreement with Mundoro Capital in January 2023, covering three exploration projects in Serbia (Trstenik, Borsko and South Timok), Mundoro has commenced initial drilling on the Borsko project.
The inaugural BHP Xplor accelerator program, supporting early-stage mineral exploration companies to find critical resources, such as copper and nickel, is now underway. Seven companies were selected into the program, which offers participants in-kind services, mentorship and networking opportunities.
Elsewhere, we continue to progress exploration activities in Canada, Chile, Ecuador, and Peru.
Variance analysis relates to the relative performance of BHP and/or its operations during the nine months ended March 2023 compared with the nine months ended March 2022, unless otherwise noted. Production volumes, sales volumes and capital and exploration expenditure from subsidiaries are reported on a 100 per cent basis; production and sales volumes from equity accounted investments and other operations are reported on a proportionate consolidation basis. Numbers presented may not add up precisely to the totals provided due to rounding.
