Deposit Section Profiles
- The Central Deposit is a manto style deposit which is confined to the contact between Permian carbonates and the overlying Jurassic rhyolites and does not permeate below the Concha limestone (100 ft - 500 ft or 30 m – 150 m).
- The Central Deposit is comprised of manganese oxides with accessory silver minerals. The host rocks (Jurassic Rhyolites and Permian sediments) strike approximately southwest-northeast and dip ± 30° to the northwest. They do not appear to be significantly disrupted by post-mineralization faulting at deposit scale.
- A resource reported in the 43-101 report on April 13, 2017 estimates 20.7 million tons in the Measured Mineral Resource category grading 4.1 ounces per ton (opt) silver, 9.2% manganese and 1.8% zinc, and 49.9 million tons in the Indicated Mineral resource category grading 1.9 opt silver, 9.6% manganese and 2.3% zinc, plus 0.35 million tons in the Inferred Mineral resource category grading 2.7 opt silver, 7.2% manganese and 3.2% zinc.
