TSX-V: DMX Corporate Presentation | January 2026 19 Historical Estimates Nianfors Uranium Property • See Forsberg, L -O., Kullman, F., Lofroth, B., 1985: Description of SKBS Mineral Reserves. Norrland. Uranrappo rt 1985-3, Sveriges Geologiska AB, IRAP 85026, p. 17 (the “ Majsaberget Occurrence Report”). • The Company views the historical estimate included in the Majsaberget Occurrence Report to be relevant and reliable. • Total, probable and presumed tonnage of the area: 5,199,558 to 10, 399,116 lbs U3O8 (2,358.48 to 4,716.96 tonnes U3O8). In total for the entire area, the po tential is estimated to be at least 12,998,896 lbs U3O8 (5,896.2 tonnes U3O8). Mineralization of two types occur in the area. Partly neosome -pegmatite mineralization and partly an impregnation mineralization in gneiss granite. The average content of the former type is estimated to be about 0.06 -0.08% U and of the latter type ab out 0.14% U. • Mineral resources under the Majsaberget Occurrence Report were classified under previous definition standards and do not match the current categories under NI 43 -101. • The Company is not aware of any more recent estimates or data available to the Compan y on the Nianfors Uranium Property. • The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Nianfo rs Uranium Property historical estimate as a current mineral resource. • The mineral resource estimates is considered to be a “historical estimate” under NI 43 -101 and a qualified person has no t done s ufficient work to classify the historical estimate as a current mineral resource and District is not treating the historical estimate a s a current mineral resource. Ardnasvarre Uranium Property • See Svensson, S.,1981:UraniumProspectinginNorrlan d.Uranrapport1981 -8,SverigesGeologiskaUn dersökning,BRAP81083,p.67 (the “Labbas Uranium Zone Report”). • The Company views the historical estimate included in the Labbas Uranium Zone Report to be relevant and reliable. • The h istorical estimate calculatio n using the polygon method has been done with respect to all drill holes. The calculatio n g ives 88 tonne U at a grade of 0.10% U and the thickness 3.4 m or 4 m horizontally (86,478 tonnes at an average grade 0.12% U3O8 containing 228,780 lbs of U3O8). • An unsuccessful attempt was made to excavate the presumed subglacial outcrop of the mineralisation discovered SW from the "main bod y". The trenching was done recently and there were a lot of d ifficulties with water in the trenches. The detailed magnetometer me asurement is finished an d the result plotted. • Mineral resources under the Labbas Uranium Zone Report were classified under previous definition standards and do not match t he current categories under NI 43 -101. • The Company is not aware of any more recent estimates or data available to the Compan y on the Ardnasvarre Uranium Prop erty. • The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Ardnasvarre Uranium Property historical estimate as a current mineral resource. • The mineral resource estimates is considered to be a “historical estimate” under NI 43 -101 and a qualified person has no t done s ufficient work to classify the historical estimate as a current mineral resource and District is not treating the historical estimate a s a current mineral resource. Sågtjärn Uranium Property • See report titled “Revised Introductory Technical R eport on Eight Uranium Properties in Northern Sweden” prepared for Con tine ntal Precious Metals Inc., revised and restated September 20, 2005 with an effective date of July 15, 2005 (the “Sågtjärn Report”). • The Company views the historical estimate included in the Sågtjärn Report to be relevant and reliable. • Based upon 47 drill holes, 50 -100 m drill space fencing, 20-100 m spacing along dril l fence. Partially drilled on a wi de grid an d is considered under-drilled. Th e authors of the Sågtjärn Report utilized a standardized cut -off of 300 ppm wherever possible to facilitate len gth weighted borehole grade and historical reserve comparisons. • Sågtjärn Report resources are based on Geological Survey of Swed en (“SGU”) documentation and the auditing by the authors of t he Sågtjärn Report of their ‘reserve’ calculation methodology, certain of the historical SGU estimates should be classified as (th en) CIM -style inferred resources on the basis that these estimates are relevant and appear reliable. • Both XR F analysis and pulse gamma logging were used in grade determinations, with the pulse gamma logging giving substantiall y higher volumes and grades. D espite this bias, the authors of the Sågtjärn Report (Forsberg and Kullman, 1981) believed that the puls e gamma logging results were more representative as they measured a greater rock volume. • Forsberg and Ku llman, 1981, calculated a wide variety of historical ‘reserve’ estimates, usin g a range of cut-off values (200 to 600 ppm in 100 ppm steps), analytical methods (XRF and PGL) and blockin g techniques (profiles and triangles). is based on their profile meth od (for comparability with other deposit estimates), using a minimum 2 m ‘width’ and 300 ppm cut -off based on XRF analysis. • It should be noted, however, that the bulk of the historical estimates, which serve as the basis for the Sågtjärn R eport hist orical estimate, are based on volume weighted grades which do not take the log normal natu re of the mineralization’s grade populations into accoun t and that, due to this non -recognition of log normality, these historical grades are likely to be slightly overstated. It is impossible to judge the degree of grade o verstatement without having carried out actual estimates, but it is consid ered u nlikely (b ut not impossible) to exceed 10 % overall. This type of grade over reporting is a common problem with o lder, traditional reserve estimates and it was/is often accounted for by cutting high values. • Mineral resources under the Sågtjärn Report were classified un der previous definition standards and do not match the current categories under NI 43 -101. • The Company is not aware of any more recent estimates or data available to the Compan y on the Sågtjärn Uranium Pro perty. • The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Sågtjärn Uranium Property historical estimate as a current mineral resource. • The mineral resource estimates is considered to be a “historical estimate” under NI 43 -101 and a qualified person has no t done s ufficient work to classify the historical estimate as a current mineral resource and District is not treating the historical estimate a s a current mineral resource.
