METALLIS RESOURCES STAKES 81 CLAIMS OVER PROSPECTIVE GEOLOGY AT THE NEWLY ACQUIRED GREYHOUND PROPERTY

VANCOUVER, BC, Feb. 29, 2024 /CNW/ - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (the "Company" or "Metallis") is pleased to announce that it has staked 81 additional mining claims in the State of Idaho, increasing the size of the recently optioned Greyhound Property (the "Property") to 677 hectares (See News Release dated February 27, 2024). This extended package of lode claims now covers all historic mineralization at the past producing Greyhound and Bulldog silver/gold mines, as well as encompassing prospective geology in underexplored terrain parallel and along strike northward of the 3.6 km mineralized Greyhound Shear.

The new claims include a recently identified, important basin–like circular structure in the northwestern area of the Property, along with outcrops of intermediate to felsic intrusive rocks thought to be Laramide in age. A geological hypothesis is being explored that this circular feature is related to a mineralized porphyritic stock belonging to the Great Falls Tectonic Zone as seen in other major nearby deposits. Recent exploration successes in the region have demonstrated that silver dominated vein deposits can be spatially related to large copper porphyry systems. With this in mind, the team has identified a number of  elevated historic copper grades from the northwesterly end of the property. This geological concept would not have been understood when the majority of the historical work took place and is something the Metallis technical team will continue to investigate with further data compilation and future boots on the ground exploration.

The team has also taken note of elevated antimony grades identified in historic assays from the Greyhound area. Multiple historic crude ore samples taken from the Greyhound Mine have returned 1-2 % antimony and suggest there may be potential for this unique strategic battery metal as countries seek to expand their sources of critical minerals and develop local supply chains. Just 36 km northwest, along strike from the Greyhound property, resides Perpetua Resources' Stibnite Mine, with mineral reserves of 5 million ounces of gold and significant antimony. Perpetua has recently been the recipient of multiple government grants totaling over US$40 million to develop and secure the antimony resource from their project.

Dave Dupre, Vice President of Exploration for Metallis commented, "The aim of staking these new claims was to ensure all exploration opportunities present on and around the Greyhound property are accounted for. Not only have historic assays demonstrated economic grades similar to producing mines in the region, the 3.6 km of untested strike length and indicators of other styles of mineralization has really excited the team. We have lots of work to do as we look to unlock the many opportunities this Property has to offer after it has sat idle for so many decades."
