Announcement PDF ASX: TKM An Emerging New Manganese District in Western Australia? Christmas Creek, Western Australia Investor Presentation | RRS Twilight | July 2026 2 56.7% Mn Sample ID OS0063065 59.65% Mn Sample ID OS0063031 3 * Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The visually observed manganese mineralisation is not representative of the entire Kuro Prospect, with drilling currently on-going to further assess the distribution of manganese. Representative drill samples are being routinely collected from the drill rig and will be analysed at ALS laboratories and reported in due course (first batch expected late July – early August, second batch expected late August – early September). Refer ASX announcements 29/06/2026 & 23/07/2026 for additional detailed information regarding visual estimates. 18 metres visual massive – semi-massive manganese* 4 Maiden Drilling at Kuro Chargeability (IP) Targets 72 Drill Holes completed in Phase 1 for 4,638m Best visuals* to date target Induced Polarisation (IP) chargeability highs 10 holes with ≥10m intersection width of massive / semi-massive visual Manganese mineralisation* Scope for follow-up drilling based on assay results (pending) and geophysics (on-going) *Visual observations only.
