Metallis Funds Idaho Hunt for Gold, Silver, and Strategic Antimony

VANCOUVER, BC – June 16, 2026 – In a move that signals renewed investor appetite for junior explorers with strategic assets, Metallis Resources Inc. has successfully closed the first tranche of a private placement, securing $1,174,550. The capital infusion is earmarked to accelerate exploration at the company's Greyhound Property in Idaho, a historic mining district with promising potential for not only gold and silver but also the critical mineral antimony.

The financing provides the Vancouver-based exploration company with the necessary runway to launch an aggressive exploration program on a property that has lain dormant for decades. For industry observers, this isn't just another financial transaction; it's a bet on reviving a piece of American mining history with modern techniques to potentially unlock minerals crucial for national security and high-tech industries.

Reviving a Historic Mining Camp

The Greyhound Property, located in Custer County, Idaho, is steeped in history. In the early 1900s, it was the heart of a bustling silver mining camp, complete with its own smelter and active mines. Metallis optioned the property in early 2024 and has since expanded its footprint to 673 hectares, consolidating a significant portion of the 3.5-kilometer-long Greyhound shear zone.

This new funding will power a comprehensive exploration campaign designed to test the ground beneath the old workings. The company has outlined plans for up to 3,000 meters of diamond drilling, a property-wide drone geophysical survey, and extensive surface mapping and geochemical sampling. This systematic approach aims to move beyond the historical data and build a modern geological model of the property's potential.

The property's location is also notable. It sits just 35 kilometers south of Perpetua Resources' Stibnite Mine, one of the largest known antimony-gold-silver deposits in the United States. This regional proximity suggests a favorable geological setting for the type of polymetallic mineralization—containing gold, silver, antimony, lead, and zinc—that Metallis is targeting at Greyhound.

The Strategic Lure of Antimony

While the prospect of gold and silver provides a traditional allure, it is the presence of antimony that adds a significant layer of strategic importance to the Greyhound project. The U.S. Geological Survey (USGS) classifies antimony as a critical mineral, essential for economic and national security but vulnerable to supply chain disruptions.

Antimony is a key component in a vast array of applications. It is used to create flame-retardant materials, harden lead alloys for ammunition and batteries, and is found in semiconductors and other high-tech electronics. However, the global supply chain is highly concentrated, with China, Russia, and Tajikistan accounting for the vast majority of production. This reliance on a few foreign sources has created significant concern among Western governments and defense contractors.

A domestic source of antimony would be a major strategic asset for the United States. The exploration work at Greyhound, therefore, carries weight beyond its potential financial returns for investors. A significant discovery could contribute to building a more resilient North American supply chain for a mineral indispensable to modern technology and defense infrastructure. The combination of precious metals with a critical industrial mineral provides a diversified value proposition that is increasingly attractive in today's volatile geopolitical landscape.

A Modern Playbook and a Diversified Strategy

To guide its exploration efforts, Metallis is drawing parallels between Greyhound and the highly successful Lucky Friday Mine, a deep, high-grade silver-lead-zinc operation also in Idaho. The company notes that both properties exhibit vein mineralization in similar geological settings. This comparison provides a valuable conceptual model for targeting high-grade ore shoots within the Greyhound shear zone. While the company prudently cautions that similar geology does not guarantee comparable results, the model offers a proven playbook for exploration in the region.

The financing itself, led by CEO Fiore Aliperti, reflects confidence in this strategy. The $1,174,550 was raised by issuing over 7.8 million units at $0.15 each. Each unit consists of a common share and half a warrant, with a full warrant allowing the purchase of an additional share at $0.20 for three years. This first tranche is part of a larger planned financing of up to $2 million, indicating the company's ambition to be well-capitalized for its upcoming work programs.

The focus on Greyhound also represents a strategic diversification for Metallis. The company's flagship asset remains its 100%-owned Kirkham Property in the heart of British Columbia's prolific 'Golden Triangle,' a region known for massive copper-gold deposits. By adding a promising U.S.-based critical mineral project to its portfolio, the company is balancing its high-risk, high-reward Canadian exploration with an asset that holds both precious metal potential and strategic industrial value, positioning itself to capitalize on multiple market trends.
