Herbert Gold Project
The Herbert Gold Deposit is an exploration stage, partially drill-tested, high-grade, gold mineralized mesothermal quartz vein system in the historic Juneau Gold Belt of southeast Alaska. Consisting of 91 unpatented lode claims located 25 km north of Juneau and to the south of Coeur Alaska's profitable Kensington gold mine. The property covers six parallel vein structures exposed at surface.
On June 12, 2024, the Company announced an updated Mineral Resource Estimate using a base case mineral resource cut-off grade of 2.50 grams per tonne gold (gpt Au) capped at 181 gpt and consists of:
-
- Indicated Resource of 1,438,500 ounces of gold at an average grade of 9.47 gpt Au in 4,726,000 tonnes.
- Inferred Resource of 515,700 ounces of gold at an average grade of 8.85 gpt Au in 1,813,000 tonnes.
- Indicated Resource of 891,600 ounces of silver at an average of 5.86 gpt Ag in 4,726,000 tonnes.
- Inferred Resource of 390,600 ounces of silver at an average grade of 7.33 gpt Ag in 1,813,000 tonnes.
- Gold & Silver Resources at the Herbert property remain open at depth and along strike.
Additional key facts and information about our Herbert Gold Property include:
- Grande Portage (GPG) has earned a 100% interest in the Herbert Gold Property.
- The property is located 25 km north of Juneau, Alaska, and lies within the 160-km long Juneau gold belt, which has produced nearly eight million ounces of gold.
- GPG has already identified 6 or more promising gold-producing main composite vein-fault structures containing ribbon structure quartz-sulfides on the property.
- Herbert Gold is one of Alaska's most promising districts and has remained remarkably underexplored until now.
- Previous company drilling has yielded numerous multi-ounce gold intercepts.
- 5th year of baseline environmental water studies completed.
In 2021-2023, the Company drilled 15,611 meters and completed 34 holes into the North vein, Goat, Sleeping Giant, Ridge, Main, Deep Trench, Floyd and Elusive veins and numerous subsidiary veins and structures in between. The Goat vein was extended to the east for more than 150 m in near surface drilling and is still open. Three intersections 100 m or more below surface intersected excellent grades up to 80 m east of the established resource.
The Ridge vein had at least five intersections with the best grades returned 200 m below its surface outcrop. The Main Vein had fourteen intercepts with results ranging up to 18.67 g/t Au over 2.63 m in 20T-8.The Deep Trench vein was tested by seven drill holes, extending mineralization 100 m farther to the east within 100 m of surface and to depths of 500 m below surface peripheral to the established resource
Highlights from recent drill programs include:
Deep Trench Vein
15.27m of 37.07 g/t gold
8.08 m of 59.91 g/t gold
11.58m of 28.41 g/t gold
Main Vein
3.05m of 72.3 g/t gold & 96.9 g/t silver
3.04m of 1,328 g/t silver and 3.42 g/t gold including .93m of 4,010 g/t silver, 7.75 g/t gold
6.46 m of 21.55 g/t gold
Goat Creek Vein
9.08m of 30.24 g/t gold
2.81m of 15.76 g/t gold
