Metallis Resources Inc. reported that following recent compilation work of its historic database, the geological team has identified highly elevated antimony assays, significantly increasing the critical mineral potential of the Company's Greyhound Property ("the Property"). The economics of critical minerals are supported by the US Infrastructure Act as demonstrated by recent high-profile moves from the U.S. Departments of Energy and Defense to finance the nearby Stibnite Mine which has significant antimony reserves and is owned by Perpetua Resources. In analyzing the historic work, the technical team has identified significant anomalous values of antimony as well as descriptions from previous operators of antimony sulfide (stibnite) observed within the mineralized zones.

Although the majority of the previous mining did not assay for antimony, a rock sampling program in 1976 returned grades that averaged 2.4% Sb from 12 samples. These historic samples ranged from 0.17% to 4.68% Sb and demonstrate highly enriched stibnite mineralization across the Property. For context, antimony prices have averaged between $5 and $6 USD per pound in the last 3 years making it approximately 1.2 times more valuable by weight than copper.

Just 38 km northwest along strike from the Greyhound property lies Perpetua Resources' Stibnite Mine, with mineral reserves of 5 million ounces of gold and significant antimony. Perpetua has recently been the recipient of a letter of interest from the Export-Import Bank of the United States for the potential debt financing of up to $1.8 billion through the "Make more in America Initiative" and the "China and Transformational Exports Program". Perpetua has also been the recipient of multiple government grants totaling over USD 40 million to develop and secure the antimony resource from their project.

Antimony supply has been largely dominated by China with no antimony mines currently operating in the USA. This has led to the classification of antimony as a high priority critical mineral defined by its economic importance and high supply risk. Governments around the world have stressed the strategic importance of this critical metal as it is used across several military applications as well as in battery storage, circuit boards and laser technology.

Furthermore, the only antimony smelter in America is in the neighboring state of Montana, currently receiving antimony ore from mines in Mexico. In addition to the antimony prospectivity, the Greyhound property's primary commodity is silver, which has significant uses in green technology and energy, with a number of lobbying groups looking to establish silver as a critical metal. Uses of silver are extensive as it exhibits the highest electric and thermal conductivity of all elements.

Over 15% of all silver production is used in photovoltaic technologies (solar panels) ensuring a consistent demand for the electrification of the planet.
