In the December 2025 quarter, Brockman Mining Limited (SEHK:159, ASX:BCK) reported continued progress in its Marillana Iron Ore Project in Western Australia, under a joint venture with Mineral Resources Limited (“MinRes”). Updated technical work continues to suggest a potential enhanced yield above 45% and product quality above 61.5% Fe, supported by sinter testwork indicating Marillana Fines can substitute for other Australian fines in standard steel mill blends.

The quarter also saw ongoing infrastructure planning in collaboration with the joint venture between MinRes and Hancock Prospecting Pty Ltd. This includes proposed new port development at Port Hedland’s Stanley Point 3 in South West Creek, along with related haul road, rail spur, and loading facilities. Meanwhile, Stakeholder and Traditional Owner consultations for the Marillana Project’s social surrounds requirements proceeded in line with legislative updates.

Encouraging reverse circulation drilling results at the 100%-owned Punda Springs project included 22 meters at 58.7% Fe from 40 meters (PRC0033) and 36 meters at 55.8% Fe from 26 meters (PRC0017). Further heritage surveys are planned at other sites, while no mineral production or development activities were reported in the quarter.

The company’s consolidated cash balance stood at HK$2.7 million as of 31 December 2025. Director-related payments in the quarter totaled HK$1.3 million, reflecting executive salaries and non-executive director fees. Brockman Mining Limited continues to maintain its portfolio of iron ore tenements in Western Australia, including 50% interests in the Marillana and Ophthalmia projects and 100% interests in Punda Springs and Duck Creek tenements.
