Inventus Provides Exploration Results from the Dorland Co-Au-Cu-Ni Prospect

TORONTO, Oct. 18, 2023 - Inventus Mining Corp. (TSX VENTURE: IVS) ("Inventus" or the "Company") is pleased to announce assay results from its drill program at the 100%-owned Dorland Co-Au-Cu-Ni Prospect, located 36 km northeast of Sudbury, Ontario.

The Company followed up on encouraging cobalt and gold values in surface prospecting with ten shallow diamond drill holes totalling 1,000 metres (m). The Dorland program is approximately 50% government-funded with the support of the Ontario Junior Exploration Program (OJEP). Drill holes intersected alteration and sulphide breccia hosted polymetallic mineralization within a steep south-dipping structural zone. Assays returned grades up to 1,700 ppm Cobalt, 1.15 g/t Gold, 3,360 ppm Copper, 3,510 ppm Nickel and 0.34 % TREO ⁽⁶⁾ (total rare earth oxides). A summary of select assay intervals and hole location details are provided in Tables 1 and 2.

The mineralized sulphide breccia was intersected over a 100-m east-west strike length with widths ranging from 3 to 15 m and was tested to a depth of 80 m. Significant zonation of Co-Au-Cu-Ni mineralization was observed in the drilling with thicker intercepts of the breccia containing high values of Co-Au-Ni. An alteration halo was also observed surrounding the Co-Au-Ni sulphide breccia, which is composed of albite, magnetite, and quartz veins with magnetite, chalcopyrite and bornite. The mineralized sulphide breccia remains open at depth and to the West (Figure 1). Inventus believes the structurally controlled mineralization observed in the drilling is likely a splay structure coming from the much larger (800 m East-West by 1,300 m North-South) area of alteration and sulphide breccia 200 m to the South.

The identification of polymetallic mineralization including the presence of rare earth elements associated with hydrothermal iron enrichment (hematite and magnetite alteration, see Figure 2) has indicated a strong analog to Iron oxide copper gold (IOCG) type mineral systems. The Dorland Prospect appears to be analogous to Inventus' Cobalt Hill Au-Co-Ni prospect located 14 km to the North; however, the presence of iron alteration and the full suite of Au-Co-Cu-Ni-REE mineralization, more typical of IOCG deposits has indicated a closer proximity to the source. This initial drill program tested a very limited area with a large prospective trend to the South which remains undrilled and an excellent IOCG-type exploration target with significant potential for discovery.

Work on an initial Sudbury 2.0 NI 43-101 Technical Report is currently advancing and regional prospecting of the area is ongoing.

Technical Information
The drill core samples collected by Inventus described in this release were transported in secure sealed bags for preparation and assay by Agat Laboratories. The samples reported were crushed in their entirety to 75% passing -10 mesh, with one 500 g subsample split and pulverized to 85% passing 200 mesh. One 50 g aliquot was taken from the subsample for fire assay (FA) with an ICP-MS/ICP-OES/AAS finish. Multi-element assays were done by ICP-OES/ICP-MS finish.
