Auriginal Mining outlines targets at Roger

Mr. Peter Cashin reports AURIGINAL IDENTIFIES FRESH MINERALIZATION TARGETS AT ROGER PROJECT THROUGH 3D MODELING, INDICATING RESOURCE UPGRADE POTENTIAL Development of a 3-D model of drill hole data from Auriginal Mining Corp.'s Roger project has identified new targets, enhancing the exploration potential of the property. In addition to previously identified VMS (volcanogenic massive sulphide) targets, the results indicate further potential to expand the historical copper-gold resource on the project (see press release dated Dec. 1, 2025). Highlights: Roger copper-gold mineralization appears truncated northeast by a north-northwest fault, dropping the continuation by approximately 200 metres, suggesting significant upgrade potential; 3-D review of historical drilling shows mineralization is not limited at depth, opening potential below 350 metres; The thickest Roger zone aligns with the core of a volcanic dome, with strongest geophysical targets on the southwestern and northeastern flanks, consistent with VMS systems; Recent geophysical results support Auriginal's interpretation of a copper-zinc-gold-silver VMS system at Roger; Geological similarities reinforce parallels between Roger and Agnico Eagle's LaRonde mine in the southern Abitibi region. 3-D resource model indicated strong potential for expansion A preliminary 3-D model has been developed using the digital exploration database for the Roger project and rendered using Leapfrog. The intent of this exercise was to complete a preliminary validation of the historical drill hole data for the property and to identify additional targets of opportunity that enhance the value proposition of the Roger project. A series of 3-D plans, geological and resource wireframe cross-sections and longitudinal sections were created. Additional validation of the model using all historical exploration information was also undertaken. In addition to the VMS model currently being evaluated by Auriginal's coming drill program, strong indications that the historical porphyry-style copper-gold mineralization identified at Roger appears to be open at depth below and along strike from the deepest drilling on the property. The planned program will be testing the depth continuity of the Roger zone and constitutes an additional resource target of interest. The longitudinal section created from the data shows a significant thickening of the Roger mineralization believed to be the axis of an interpreted volcanic dome or cryptodome, the required heat source for a VMS mineralizing system. The most important base metal sulphide intersections returned from historical drilling (see Kintavar's press release dated Nov. 12, 2025) occur along the northeastern and southwestern flanks of the interpreted dome structure axis, in support of the VMS model developed for the property. The longitudinal image also indicates the Roger zone to plunges toward the northeast. Auriginal's visualization indicates that the Roger zone is abruptly cut by a north-northeast-striking fault, which shows significant thickness changes of the volcanic stratigraphy on either side of the fault plane. Also, the alteration envelope that characterizes the periphery of the Roger zone appears to have been displaced vertically down by at least 200 metres on the east side of the interpreted fault. Auriginal believes that this is strong indication that the Roger porphyry mineralization remains open toward the northeast and at depth. A strong borehole electromagnetic (BHEM) was detected from Auriginal's earlier survey work (see press release dated Nov. 12, 2025), believe to be related to massive base metal sulphide mineralization has also been observed in that direction. Revisions to the proposed diamond drill program Given the enhanced mineralization potential identified from the 3-D visualization work, modifications to the previously proposed drilling have been made (see press release dated Dec. 4, 2025). Adjustments to the drill hole positioning and lengths are presented in Table 1. Drilling is expected to start early March, 2026. About Auriginal Mining Corp. Auriginal is a Quebec-focused copper and gold company with one of the province's largest and most diversified exploration portfolios. Its 100-per-cent-owned flagship Roger project, located in the Chibougamau district, hosts a known gold-copper deposit with strong potential to host volcanic-hosted polymetallic massive sulphide deposits. With a diversified pipeline of greenfield projects across Quebec's best-known mining regions and backed by the Ore Group's proven exploration and capital markets team, Auriginal has a clear focus on discovery and growth for copper, zinc and gold. The company is well positioned to immediately execute an aggressive exploration and acquisition strategy and attract broader market attention.
