Toronto, Ontario — January 15, 2026 — Leads & Copy — Auriginal Mining Corp. (TSXV: AUME) announced the development of a 3D model of drillhole data from the Roger Project has identified new targets, enhancing the exploration potential of the property.
Auriginal also said the results indicate further potential to expand the historical Cu-Au resource on the project, in addition to previously identified VMS targets.
The company said a preliminary 3D 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 drillhole data for the property and to identify additional targets of opportunity that enhance the value proposition of the Roger.
Auriginal said a series of 3D 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.
Auriginal said that in addition to the VMS model currently being evaluated by its upcoming drill program, there are strong indications that the historical porphyry-style Cu-Au mineralization identified at Roger, appears to be open at depth below and along strike from the deepest drilling on the property. Auriginal said 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 (see Figure 1) believed to be the axis of an interpreted volcanic dome or cryptodome, the required heat source for a VMS mineralizing system. The most important basemetal sulphide intersections returned from historical drilling (see Kintavar Press Release – November 12, 2025) occur along the NE and SW flanks of the interpreted dome structure axis, in support of the VMS model develop for the property. The longitudinal image also indicates the Roger zone to plunge toward to NE.
Auriginal said its visualization indicates that the Roger zone is abruptly cut by an NNE-striking fault (see Figure 2) which shows significant thickness changes of the volcanic stratigraphy on either side of the fault plane. Also, the alteration envelop that characterizes the periphery of the Roger zone, appears to have been displaced vertically down by at least 200 m on the east side of the interpreted fault. The company believes that this is strong indication that the Roger porphyry mineralization remains open towards the NE and at depth. A strong Borehole EM (BHEM) was detected from earlier survey work (see Press Release, November 12, 2025), believe to be related to massive basemetal sulphide mineralization has also been observed in that direction.
Auriginal also announced revisions to the proposed diamond drill program. Given the enhanced mineralization potential identified from the 3D visualization work, modifications to the previously proposed drilling have been made (see Press Release, December 4, 2025). Adjustments to the drillhole positioning and lengths is presented in Table 1 (see Figure 3). Drilling is expected to start early March 2026.
Auriginal is a Quebec-focused copper and gold company with one of the province’s largest and most diversified exploration portfolios. Its 100%-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.
