Wisner Properties JV with Lonmin
Wallbridge's Wisner properties in Sudbury are being explored for copper and PGEs as part of the North Range joint venture currently funded by Lonmin Plc.
The Wisner properties include several high grade Cu-PGE occurrences and over a dozen identified exploration targets within a 10 km long prospective belt of geology surrounding Wallbridge's Broken Hammer Cu-PGE open pit mining project and adjacent to several Ni-Cu-PGE deposits owned by Vale and Glencore.
The Southwest Zone, South Zone, and Rusty Blade target areas comprise a 2.5 kilometre long trend of discontinuous high-grade Cu-PGE occurrences.
Grab samples from the Southwest zone contain up to 10.55 % Cu and 9.87 g/t Pt+Pd+Au and drilling has traced mineralization to 120 metres depth. Previous drilling highlights include 0.5 m of 26.69 g/t Pt+Pd+Au, 2.35 wt.% Cu and 1.25 wt.% Ni from 65.5 to 66.0 m in WIS-078; 13.7 m of 0.99 g/t Pt+Pd+Au, 0.11 wt.% Cu and 0.04 wt.% Ni from 109.8 to 123.5 m in WIS-078, and 1.9 m of 2.23 g/t TPM, 7.87 wt.% Cu and 0.12 wt. % Ni from 27.1 to 29.0 m in WIS-088.
In 2012, a small field program including prospecting, trenching and channel sampling extended the Southwest Zone 80 metres to the northeast along an IP geophysics anomaly. Four hundred metres of this anomaly is untested by drilling. Grab sample highlights from this program include 3.90 % copper with 6.62 g/t TPM, 2.84 % copper with 4.34 g/t TPM, and 2.81 % copper with 3.96 g/t TPM. Channel sample highlights from this program include 1.28 metres containing 1.35 % copper with 3.90 g/t TPM, 1.99 metres containing 0.71 % copper with 2.40 g/t TPM, and 0.16 metres containing 5.59 % copper with 5.39 g/t TPM.
In the South Zone, grab and channel samples contain up to 25.50 wt.% Cu and 151.95 g/t TPM. Drill hole WIS-004 intersected 3.35 m of 2.30 g/t TPM, 0.18 wt.% Cu and 0.05 wt.% Ni from 5.00 to 8.35 m. The South zone area was only explored to shallow depth (150 m) and the Sudbury breccia structure hosting this mineralization has not been drilled outside of the trenched area.
The Rusty Blade Cu-PGE occurrence was identified in the spring of 2014 when WIS-141 intersecting 1.00 metre containing 0.14 g/t TPM (0.062 g/t Pt, 0.065 g/t Pd, and 0.011 g/t Au), and 0.10% Cu from 31.26 to 32.26 metres down-hole. Subsequent prospecting has identified copper mineralization in outcrop.
The Twisted Wrench occurrence was identified in the spring of 2014 when drilling intersected weakly anomalous mineralization in a new area.
