The Wabassi property is located in northwestern Ontario, 60 km south of Northern Shield’s Highbank Lake project and 100 km south of the “Ring of Fire” Ni-Cu-PGE and chromite deposits. The Wabassi property is being explored for reef-hosted platinum-group elements (PGE) and massive sulphide Ni-Cu-(PGE) deposits as well as Cu-Zn-Ag-Au volcanogenic massive sulphide (VMS) deposits. The proposed road to access the Cliffs Natural Resources owned Black Thor and Black Label chromitite deposits in the “Ring of Fire” passes through the Wabassi property.
The Wabassi property is currently owned 49% by Northern Shield, with Discovery Harbour Resource Corporation having earned a 51% interest by spending $3.4 million in exploration expenditures. The Property is composed of over 600 square kilometers of claims at the heart of the Wabassi VMS camp including a 40 km stretch of the stratigraphy that hosts the two VMS occurrences discovered to date.
The 2010 drill program resulted in the discovery of high-grade Zn-Cu-Ag mineralization (Zone A2) and Cu-Ni-Ag (Zone A1) in a VMS setting on the edge of the Wabassi Intrusion. Follow-up drilling in 2011 resulted in the discovery of another VMS occurrence at Anomaly E (Zone E). These discoveries define the existence of a new VMS camp at Wabassi. Multiple styles of VMS mineralization have been observed in the Wabassi VMS camp.
Zone E consists of a typical bimodal mafic-felsic VMS system similar to the Flin Flon VMS camp in Manitoba, where the Cu-Zn-Ag mineralization is hosted in the felsic volcanic rocks and controlled by synvolcanic faults. Multiple Zn and Cu-Zn lenses have been found and the mineralized horizon is still open along strike and at depth. Zone A1 and Zone A2 both display VMS style mineralization at the margin of the Wabassi Intrusive Complex. Many geophysical targets remain to be tested in the area.
In the process of drill testing Anomaly “N” (a high priority VTEM conductor defining a massive sulfide target), a quartz-carbonate alteration zone with a veinlet of visible gold was intercepted at 98.8 metres in drill-hole 13WA-33. The 0.15 metres sample assayed 2,530 g/t Au (73.8 ounces/ton). A second interval assayed 5.86 g/t Au from 100 to 101.1 meters. The auriferous zone appears to be related to an intermediate intrusive dike or sill and occurs at the contact of this intrusive and the altered mafic volcanic rocks.
This intersection of gold is the fourth gold discovery that has been made to date within the Wabassi-Tempest properties and the second to contain visible gold. Globally, gold mineralization is present in a majority of VMS districts.
Platinum Group Elements (PGE) Prospectivity
In addition to the Max intrusion on the Max Property to the west, two mafic-ultramafic intrusions have been identified on the main Wabassi Property (Wabassi Main and Wabassi North). Wabassi Main is a well layered mafic-ultramafic intrusion composed mostly of gabbronorite, olivine-gabbronorite, troctolite and harzburgite, whereas Wabassi North is composed mainly of gabbro.
While drilling to date has not yet returned the expected results in terms of PGE mineralization, it has definitely highlighted the enormous potential for Ni-Cu-(PGE) and PGE concentration in still unexplored portions of the Wabassi and Max intrusions and their feeder systems.
