Operations
Heath Steele Project
Trevali holds an option to acquire 100% of the formerly producing zinc-lead-silver-copper-gold mine located adjacent to the Company's Stratmat Deposit and approximately 35 km south-southeast of the Caribou Mine. Mining operations at Heath Steele were carried out by a variety of companies (including Noranda) discontinuously between 1957 and 1999. Over Heath Steele’s long mine life, zinc, lead, copper, silver and gold were extracted from several zones on the property.
Mined Zone | Million Tonnes | Zn (%) | Pb (%) | Cu (%) | Ag (g/t) |
|---|---|---|---|---|---|
Boundary Zone and N-5 | 1.137 | 8.11 | 2.98 | 0.35 | 44.0 |
Heath Steele ACD Zone | 2.472 | 7.38 | 1.73 | 0.73 | 76.7 |
Heath Steele B Zone | 20.723 | 4.79 | 1.75 | 0.98 | 65.5 |
Combined Total: | 24.332 | 5.21 | 1.81 | 0.93 | 65.6 |
Geology and Mineralization
The current target on the project, E-Zone, has VMS mineralization exposed at surface and has been previously tested and defined by more than 150 historic drill holes. Based on the available historic drill hole data, E-Zone appears to be comprised of two stacked sulphide lenses each approximately 150 metres in length and with thicknesses ranging from 5-30 metres. The lenses merge towards surface and have a vertical continuity of approximately 200 metres.
Planned Programs
Additional exploration work is planned for the Heath Steele claim group in 2018.
