The Harri project is part of Wallbridge’s 830 km2 Detour Fenelon Gold Trend land package. The project is located between the Company’s Martinière and Fenelon Gold projects and covers 20 kilometres of the Sunday Lake Deformation Zone ("SLDZ"), a major east-west structure in the northern Abitibi greenstone belt which hosts the Detour Lake gold mine in Ontario (Agnico Eagle Mines).
At the current time there are no known significant occurrences of gold or base metals mineralization on the Harri project. The geological conditions support the potential for VMS discoveries and potential for gold along structural zones and splays of the regional SLDZ.

Exploration activities on the Harri project dates back to the late 1950s, however the property remains largely unexplored. A number of geophysical surveys were carried out followed by diamond drilling of the EM and magnetic anomalies. The majority of the 41, shallow drill holes (drilled dominantly in the 80s) are located within the central part of the project. A few holes were reported to have intersected zones of semi-massive sulfides with anomalous copper values.
The Harri project is extensively overburden covered and thus the majority of the geological information comes from drilling completed to date and available geophysical data. The project geology is interpreted to be a mafic volcanic dominated sequence with less interflow, greywacke type sedimentary units and minor felsic volcanic and intrusive lithologies. The magnetic data suggests limited mafic intrusive activity.
Along the southern margin of the project what is interpreted to be an anticlinal-dome type feature exposes a core of sedimentary rocks across approximately 10 kilometres. This highly unusual formation is ringed by an extensive series of electromagnetic (EM) conductors. Historic drilling in this area has been directed mainly at VMS (Zn-Cu) targets with limited success. The base metal occurrences are limited to the margins of the sedimentary anticline and are hosted within either graphitic mudstone units or a mixed volcanic and sedimentary portion of the sequence. The stratigraphy in this area remains poorly understood. The world-class Selbaie Cu-Zn-Ag-Au VMS deposit is located less than 12 kilometres to the south.
The SLDZ, which flanks the Harri project to the south, is only sparsely tested across the project. No gold mineralization has been encountered to date.
A prominent north-trending, late (Proterozoic?) dyke cuts across the east-west trending structures and stratigraphy on the east side of the Harri project. Significant movement (both lateral and vertical) is interpreted across this feature which appears to fill a northwest fault structure. The Bug Lake Gold Trend on the adjacent Martinière project features a similar orientation.
