Columbia Gold & Silver Project
Sentinel Metals’ 100%-owned Columbia Gold & Silver Project is located in West Montana, 8.1 miles east of the town of Lincoln and 39.8 miles northwest of the capital city, Helena.
Existing large-scale Mineral Resource
The Columbia Project hosts a JORC Inferred Mineral Resource Estimate of 23.6 million tons grading 1.34g/t Au for 920,000 ounces of contained gold.
Large independent Exploration Target
In addition to the Mineral Resource, the Project also hosts an Exploration Target of 24.3-29.8 million tons grading 1.1-1.4g/t Au for 800,000-1.2Moz of contained gold.
Tons and grades in the Exploration target are represented as a low and high range and are an approximation only. The potential quantity and grade of the Exploration Target are conceptual in nature and there has been insufficient exploration drilling conducted to estimate a Mineral Resource for the Exploration Target.
The Exploration Target has been prepared in accordance with the JORC Code (2012).
The current Resource is just the beginning
Sentinel Metals benefits from a vast historical drill database that includes more than 34,000 samples.

* The MRE is constrained within a US$2,200 / Au oz optimised shell and above a 0.4865g/t AuEq cut-off grade. The MRE has been optimised and reported using a gold equivalent value based on the following formula: AuEq = Au g/t + Ag g/t (Agoz $(30)/Auoz $ (2200) x Ag recovery (0.77) / Au recovery (0.96))
