METALLIS PRIORITIZES HIGH IMPACT DRILL TARGETS AT GREYHOUND PROPERTY, IDAHO
Next Steps
-
Drone Magnetic Survey : This survey will be initiated to pinpoint the location of the shear in areas of overburden and help identify important mineralizing cross structures. -
Induced Polarization Survey : The chargeability data will be used to highlight the thickest zones of high-grade mineralization and aid in refining drill targets. - Drill Targets: Metallis has focused on three high-priority targets for 2025 drilling: 1350', Bulldog, and Birdie.
- Permits: As the proposed work is on patented claims, only one minor permit is required for the proposed work.
- Service Providers: The team is in the process of qualifying bids from multiple service providers.
Proposed 2025 Drill Targets
The three highest-priority drill targets were identified by interpretation of historic results and extensive work by the Metallis team over the last year. These targets will be tested with multiple drillholes in a program planned to total 2,000 m. No drilling has ever been conducted on the property so all targets will see their first ever drill testing during the inaugural program planned for the upcoming field season. The three highest priority drill targets are described below.
1350' Target
Drilling at the 1350' will be used to expand a high-grade silver/gold/antimony zone mined historically in the 1980's with multiple drill holes focused above and below the Lower Rufus adit. Historical channel sampling† along a 36.9 m length of this adit returned 1.85 g/t Au and 785 g/t Ag (10.6 g/t AuEq*), confirming a high-grade mineralized shoot exists at this location. Three grab samples taken historically from this same zone also provided high-grade results up to: 3.27% Sb, 8,770 g/t Ag, 1.87 g/t Au, 18.7% Pb, and 20.8% Zn.
Prospective areas above and below the 1350' mineralized zone will be targeted for drilling during the 2025 season as historic mining has only tested one of this extensive shear system. Vertical extensions of the mineralized zones have been validated through multiple mining raises and historic descriptions. Vertical continuity can be traced to a surface trench located 200 m above the adit that returned 2.0 g/t AuEq* over 4 m with 3 nearby float samples returning grades > 10 g/t AuEq*. Given the long strike length of the Greyhound shear system, it is probable that there is significant depth potential on the property, including at the 1350' zone. This can be exemplified by
Bulldog Target
The Bulldog target has demonstrated rich antimony mineralization as well as very strong gold and silver results from sampling completed by Metallis in 2024. Highlights include chip sampling that returned 353 g/t Ag and 0.61% Sb over 3 m, including a 15 cm high-grade quartz sulfide vein, outcropping over 13 m in length, that produced an average of 2.68% Sb, 1,624 g/t Ag and 0.60 g/t Au from 4 samples (27.9 g/t AuEq*). This vein was missed by the former operator when excavating a surface cut and speaks to the well-endowed system as they prioritized mineralization adjacent to this vein. A very high-grade antimony sample has also been returned from a nearby stockpile that contained 4.54 % Sb.
A functioning access road was built to this target to accommodate a historic surface cut from the 1980's and a historic adit from the early 1900's. This road will be utilized for efficient drill testing and will improve economics for the upcoming drill program. The Bulldog represents one of the largest areas of exposed mineralization at surface and the shear zone is up to 15 m across with multiple anastomosing quartz sulfide veins that total 3 m. This target has also never been drilled, and the geological team intends to test this high-grade mineralization with multiple planned drillholes.
Significant gold and silver were found at the Birdie target, where two trench cuts located 70 m apart as well as historic adits both revealed a sizeable shear zone with quartz sulfide veins of 1-3 m width. An 80 cm block from Upper Birdie cut yielded 4,900 g/t Ag with other grab samples nearby returning up to 67.0 g/t AuEq*. A 50 cm quartz sulphide vein sampled from Lower Birdie cut returned 18.15 g/t Au, and six out of seven samples from the phase-two program at the Lower Birdie returned >1.8 g/t Au. These findings emphasize the Birdie as a gold rich zone and highlight the exceptional gold values that were overlooked historically. This target is located on a parallel trend to the main Greyhound shear and suggests additional potential lies in adjacent shear zones that have not been well explored. Access is along a previously constructed road allowing for convenient adjustments and expansion drilling.
About the Greyhound Property
In
The Greyhound targets are hosted by prominent shear zones with polymetallic quartz - sulphide veins containing elevated concentrations of Au, Ag, Sb, Pb and Zn. They are comparable to numerous mines in

A grab sample is taken from a rock outcrop that is being assessed for the presence of valuable elements and are therefore selective. They are solely designed to show the presence or absence of mineralization and are not intended to provide nor should be construed as a representative indication of grade or mineralization at the Property.
Chip-channel sampling involves taking contiguous rock chip samples along a line to define the width and grade of a zone. Commonly, these are taken perpendicular to the strike of the mineralized zones
†The grades of the Greyhound 1350' zone are historical and cannot be verified by Metallis although there is no reason to believe they are inaccurate.
