The Headwater drill program has been planned to target a roughly 500-m-long segment of the Main Ridge Fault zone. This zone presents the most concentrated silicification and epithermal quartz veining at the property surface. These include rock grab samples returning gold values of up to 170 g per tonne. This structure will be targeted by four preliminary drill holes to depths of up to about 225 m below the surface.
Highlights
- The Mahogany Project is situated about 20 km northwest of Integra Resources’ DeLamar deposit in southeastern Oregon
- Headwater focuses on high-grade epithermal vein mineralization at depths that were not tested by restricted shallow historic drilling
- Extremely strong gold values were achieved in Headwater rock grab samples (up to 170.00 g/t Au) in a high-level epithermal environment
About the Mahogany 2021 Drill Program
The Mahogany Project is situated in Southeastern Oregon, 20 km to the northwest of the DeLamar deposit owned by Integra Resources. Headwater geologists used a range of geophysical and geological targeting tools to identify a high-level epithermal system with high-grade gold up to 170.0 g/t Au (from rock grab samples) at the surface.
Restricted historic drilling hit various zones of anomalous gold mineralization within 100 m of surface (for example, MH88-36-01 returned 10.7 m grading 0.73 g/t Au starting at 53.4 m) but did not test the vein target at depth. The Headwater program will test the highest priority targets and is designed to include an initial four holes.
The focus of the drilling will be on a 500-m segment of the Main Ridge Fault Zone, interpreted by Headwater Geologists as the main feeder to the alteration cell found at the surface. Drilling has been designed to reach vertical depths of 100–225 m, with the target of high-grade precious metals in the inferred epithermal boiling zone. At Mahogany, historic drilling has never reached these depths.
