Announcement PDF INVESTOR - 1 ASX: DTM N O V 2 6 , 2 0 2 5 1 INVESTOR - 2 ASX: DTM FORWARD LOOKING STATEMENTS AND CAUTION Certain statements contained in this document constitute forward looking statements. Such forward looking statements are based on a number of estimates and assumptions made by the Company and its consultants in light of experience, current conditions and expectations of future developments which the Company believes are appropriate in the current circumstances. This presentation contains visual estimates of mineralisation, and the company would like to stress that visual estimates of mineralisation abundance contained in this announcement should never be considered a proxy or substitute for Laboratory analysis. Visual estimates potentially provide no information regarding concentration of economic grades or factors, impurities or deleterious physical properties relevant to valuation. These estimates and assumptions while considered reasonable by the Company are subject to known and unknown risks, uncertainties and other factors which may cause the actual results, achievements and performance of the Company to be materially different from the future results and achievements expressed or implied by such forward- looking statements. Investors are cautioned that forward looking information is no guarantee of future performance and accordingly, investors are cautioned not to place undue reliance on these forward- looking statements. The Company confirms that in the subsequent investor presentation that it is not aware of any new information or data that materially affects the information included in the presentation and that all material assumptions and technical parameters underpinning the estimates in the relevant market announcements continue to apply and have not materially changed.
