METALLIS ANNOUNCES 2026 DRILL PROGRAM UNDERWAY AT GREYHOUND PROJECT, IDAHO

MWN-AI** Summary

Metallis Resources Inc. has officially commenced its 2026 exploration program, announcing that diamond drilling is underway at its Greyhound Project in central Idaho. Following the successful setup of an operational exploration camp, the first drill hole, GH26-12, is targeting the 1350 Zone, positioned near the Lower Rufus Adit. This drilling will explore the principal Rufus Vein along with other relevant mineralized structures. The initial focus is on the Rufus Zone, where previous exploration has indicated a significant mineralized shear zone containing quartz-sulphide veins rich in gold, silver, lead, zinc, and antimony.

Dave Nuttall, Vice President of Exploration, highlighted the refined geological understanding gained from the 2025 exploration season, enabling a more targeted drilling strategy for 2026. This year's program has been designed to specifically test high-grade mineralization targets, in contrast to the broader approach taken previously. Following drilling at the 1350 Zone, Metallis plans to further investigate the 1100, 1000, and 500 Zones.

In addition to drilling, the 2026 exploration program includes geological mapping, trenching, and surface geochemical sampling aimed at advancing other target areas, including Republican, Bulldog, Akita, Idaho, Ridge Cut, and Birdie. With plans for approximately 3,000 meters of diamond drilling throughout the summer, the company is set to provide regular updates on exploration progress and assay results.

Metallis Resources, based in Vancouver, maintains a focus on gold, copper, and silver exploration within its portfolio, encompassing both the Greyhound Property in Idaho and the Kirkham Property in British Columbia.

MWN-AI** Analysis

Metallis Resources Inc. (TSXV: MTS) has commenced its highly anticipated 2026 drill program at the Greyhound Project in Idaho, focusing initially on the Rufus Zone. This program marks a pivotal moment for the company, as it builds on the insights gained from its 2025 exploration campaign and targets specific high-grade mineralized structural positions.

Investors should consider the strategic implications of this drill program, particularly the ongoing testing of multiple zones, including the 1350, 1100, 1000, and 500 Zones. Recent geological interpretations suggest that the structural controls on mineralization at the Rufus Zone are better understood, which could lead to more efficient resource definition and, potentially, higher-grade discovery. The company’s goal of delineating mineralized shoots, rather than merely testing so-called mineralized areas, reflects an evolving exploration strategy that might improve the risk-return profile for investors.

Metallis has allocated approximately 3,000 meters of diamond drilling, which, coupled with geological mapping and surface sampling, is likely to refine existing targets and stimulate interest in the broader potential of the Greyhound project. Notably, the geological characteristics aligned with the Lucky Friday Mine lend credibility to the anticipated outcomes, although investors should remain cognizant of the cautionary note regarding comparable results.

As drilling progresses throughout the summer, expected assay results could serve as key indicators of the project's viability. Stakeholders should watch for updates that may influence share price volatility, given the speculative nature of mining exploration stocks.

In summary, Metallis Resources presents a compelling investment proposition for those looking to gain exposure to the mining sector. However, investors should maintain an awareness of the risks involved, considering both market sentiment and the inherent uncertainties of exploration success.

VANCOUVER, BC, July 16, 2026 /CNW/ -- Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (the "Company" or "Metallis") is pleased to announce that diamond drilling is now underway at its Greyhound Property ("Greyhound" or the "Project") in central Idaho, marking the next phase of the Company's 2026 exploration program.

Following the successful completion of mobilization activities announced last week, construction of the exploration camp has been completed, and the site is now fully operational. The diamond drill arrived at camp on July 8, and has since been commissioned, with the Company's geological team completing final drill collar surveying and staking in preparation for the season's first drill hole.

The 2026 drill program will initially focus on the Rufus Zone, where the Company's 2025 exploration campaign confirmed a broad mineralized shear zone hosting multiple quartz-sulphide veins carrying anomalous gold, silver, lead, zinc and antimony mineralization. Geological interpretation completed over the winter has refined the structural model of the system and identified several priority targets designed to better define the geometry and continuity of interpreted higher-grade mineralized shoots.

The first drill hole of the season, GH26-12, is targeting the 1350 Zone adjacent to the Lower Rufus Adit. The hole will test the principal Rufus Vein together with interpreted mineralized structures located both above and below the vein. Drilling at the 1350 Zone will evaluate the continuity, grade, thickness and structural geometry of the mineralized system and provide critical information to guide subsequent drilling throughout the Rufus zone.

Following drilling at the 1350 Zone, the Company plans to advance testing of the 1100, 1000 and 500 Zones, targeting interpreted high-grade shoots identified from historical underground chip sampling and the Company's geological modelling which was updated following the 2025 exploration program.

Dave Nuttall, Vice President of Exploration, commented "Interpretation work of our 2025 drill season has fundamentally improved our understanding of the Greyhound Shear and, in particular, the structural controls on mineralization at Rufus. As a result, the program this season is far more targeted than in 2025. Rather than simply testing mineralization, we are now drilling specific structural positions where we believe higher-grade shoots may develop. Beginning at the 1350 Zone allows us to test our updated geological model while collecting critical information that will guide the remainder of the program."

While drilling represents the primary focus of the current phase of exploration, geological mapping, trenching and surface geochemical sampling will continue throughout the field season. These programs are designed to further refine existing targets and continue advancing the Republican, Bulldog, Akita, Idaho, Ridge Cut and Birdie target areas toward future drill testing.

Fiore Aliperti, President and CEO of Metallis, added "Seeing the first drill turning at Greyhound is an exciting milestone for the Company. Last year's inaugural drill program confirmed the presence of a significant mineralized system, Dave Nuttall's interpretation has provided the geological understanding necessary to design a much more focused exploration campaign. We believe the 2026 program represents an important step in unlocking the broader potential of the Property, and we look forward to providing shareholders with regular updates as drilling progresses."

The planned 2026 exploration program includes approximately 3,000 metres of diamond drilling, complemented by geological mapping, trenching and geochemical sampling. Together, these programs are designed to improve the Company's understanding of the Greyhound Shear Zone, expand known mineralization and identify additional drill-ready targets across the broader property.

The Company expects drilling to continue throughout the summer exploration season, with assay results to be released as they become available.

About the Greyhound Property 

In February 2024, the Company optioned the Greyhound Property, located in Custer County, Idaho, approximately 42 km northwest of the town of Stanley and 35 km south of Perpetua Resources' Stibnite Mine. The property was the center of an active silver mining camp in the early 1900's and at one point contained a smelter and two active mines situated along the 3.5 km Greyhound shear. In 2024, the Company staked additional land around Greyhound for a total current property size of 673 hectares.

The mineralization is hosted by prominent shear zones with polymetallic quartz-sulphide veins containing elevated concentrations of gold, silver, antimony (a critical mineral), lead, and zinc.

Greyhound shares certain geological characteristics with the Lucky Friday Mine in northern Idaho. Both properties exhibit vein mineralization occurring as fracture-fillings, disseminations, and tabular masses of galena and tetrahedrite along with accessory pyrite in a gangue of siderite, calcite, and quartz. The Lucky Friday zone is a singular, curved tabular body that dips almost vertically. The vein at Lucky Friday has a strike length of up to 450 m and a width that varies from centimeters to as much as 6 m. The average varies from 1.2 to 1.8 m over the full length (SLR, 2022).

Metallis states that while the Lucky Friday Mine may share some geological similarities with the Greyhound Property, no representation is made that comparable results will be achieved at Greyhound.
