This presentation contains forward-looking statements that are subject to risk factors, many beyond the Company's control. Actual results may differ materially from those expressed or implied. The Company provides no assurance that actual results will meet expectations and does not undertake to update this information. Exploration results, JORC Code and conceptual material. Exploration results referred to here have been previously released to ASX. Grades and resource figures attributed to third parties (for example Basil, Blackadder and Baldrick) are from prior public reporting by those parties and are not Litchfield estimates. Data and interpretation are kept separate throughout. The mineral systems framework, analogue comparisons and any reference to target scale are conceptual, are labelled as interpretation, and are not an Exploration Target or Mineral Resource under the JORC Code. Landholding Figures Approximate landholding includes granted tenements and exploration licence applications. Certain applications are subject to competitive assessment and regulatory approval, and there is no assurance they will be granted. Total landholding may therefore change.

RTP MAGNETICS · OONAGALABI PROSPECTIVE HORIZON AND MITRE VTEM CONDUCTOR PICKS · EL PICKS · EL 32279 BEYOND THE CARBONATES New drilling and geophysics show mineralisation is not restricted to the carbonate units and multiple styles of mineralisation exist. FEEDER-STYLE CONDUCTORS VTEM priority conductors may represent feeder structures, or point to a larger, more complex mineralising system. ADDED COMPLEXITY Magnetite–Au–Bi mineralisation (OGRC002) suggests additional system complexity beyond the original model. FOCUSED ON THE BOUNDARY Vertically extensive magnetic anomalies focus along the Aileron–Irindina boundary. Oonagalabi now reads as part of a broader mineral system.

Magnetics revealed the architecture Highlighted deep-seated structures and intrusive domains, revealing a more extensive and structurally complex system than previously recognised. VTEM unlocked blind mineralisation Identified previously unrecognised conductors and blind sulphide mineralisation on the Irindina and Aileron, beyond the known horizon.
