  • Overview

    The Detour East project is part of the 739 km2 Detour Fenelon Gold Trend land package acquired with the acquisition of Balmoral Resources Ltd. It covers over 20 kilometres of the Sunday Lake Deformation Zone ("SLDZ") and the Lower Detour Deformation (“LDDZ”) stretching east from the Québec-Ontario border. The SLDZ is a major east-west structure in the northern Abitibi greenstone belt which hosts the Detour Lake gold mine in Ontario (Kirkland Lake Gold), approximately 11 kilometres to the west, whereas the LDDZ hosts Kirkland Lake Gold’s Zone 58N gold deposit, also on the Ontario side of the border. 

    The main gold occurrences on the property are the Lynx and Rambo prospects with highlight drill hole intersections of 9.61 g/t Au over 6.25 m and 1.22 g/t Au over 20.10 m, respectively.

  • Brief History

    Historically, the major exploration activity in the region was 25 kilometres to the southeast with the discovery of the Selbaie VMS deposit in the mid-1970s. At about the same time, across the border in Ontario, the Detour Lake gold deposit was discovered during a base metal exploration program. 

    Drilling by Lynx Exploration (now Encana) in 1987 led to the discovery of the Lynx gold zone, which was subsequently explored by Cyprus Canada and American Bonanza. Following the Lynx discovery, Coleraine Exploration discovered the Rambo gold zone to the east (approximately 30 drill holes). Radisson Mining Resources became the property owner in 1995 and conducted several exploration campaigns, including 13 holes totaling 4,016 metres at the Lynx prospect. 

    In late 2010, Balmoral Resources Ltd. (“Balmoral”) optioned the property from Radisson and by 2012 Balmoral held a 100% interest in the property. Short drilling programs (for a total of ~2,400 metres) and IP surveys were completed in 2011 and 2012. In 2016, Balmoral completed a 6 drill holes and extended the Lynx gold zone with an intercept of 0.91 g/t Au over 14.25 m, including a higher-grade interval of 5.53 g/t Au over 1.58 m. It also completed an extensive geophysical survey (induced polarization survey) in the northeast part of the property. In 2017, Balmoral completed 15 drill holes totaling 4,695 metres on a variety of grassroots targets located on the northern half of the Detour East property. Only minor gold mineralization was intersected in 2 holes.

  • Geology and Mineralization

    Two major regional structures cross the Detour East project – the SLDZ to the north and the LDDZ to the south. Magnetic patterns suggest dominantly east-west trending stratigraphy locally cut by northwest to northeast trending fault structures. These secondary structures, which can crosscut or splay out of the SLDZ play an important role in localizing gold mineralization at the nearby Detour Lake mine and also at the Martinière and Fenelon gold systems to the east. 

    On the northern portion of the property, gold mineralization has been identified in association with quartz-tourmaline-sulphide veins and zones of strong sericite alteration within regionally extensive fault corridors related to the SLDZ. 

    To the south, along the trace of the LDDZ, gold mineralization has been intersected in historic drilling in numerous locations along the 13 kilometres strike length. 

    The Lynx gold zone is an east-west striking, shallowly west-plunging zone of quartz-veining with associated pyrite and rare visible gold hosted along the contact between andesitic and mafic volcanic rocks, proximal to a diorite intrusion. Drilling has traced the Lynx zone for approximately 250 metres along strike at shallow depths. The Lynx zone exhibits widths of 50 to 100 metres and drill indicated thicknesses of 0.40 to 13.40 metres. Geological modeling by Balmoral suggested that the gold mineralization at Lynx may be associated with faulting in the nose region of a fold structure drag folded along the margins of the LDDZ (similar model to the high-grade Casa Berardi gold mine to the south). 

    The Rambo gold zone is located approximately 2.5 kilometres east of the Lynx zone. Historic drilling on the Rambo area is highlighted by a number of high-grade intercepts associated with quartz-carbonate veining located along a 100 metre long stretch of the LDDZ.
