Detour Gold has reported the final results from its 2015 summer drilling program at its Lower Detour project, located approximately 6 km south of its flagship Detour Lake gold mine in northeastern Ontario. An infill drilling program of 30,408 m in 55 holes was conducted at 50-m spacing to test the continuity and extent of the gold mineralization within the project’s Zone 58N.
The drilling continued to demonstrate the continuity of the Lower Detour gold mineralization at depth. Visible gold was observed in 46 of the 53 drill holes that tested Zone 58N. To date, gold mineralization has been intersected over an east-west strike length of 450 m and from surface to a depth of 800 m. The mineralized system remains open at depth.
Detour Gold is continuing its Lower Detour drilling campaign this winter with an infill and step-out drilling program of up to 75,000 m. Detour Gold COO Pierre Beaudoin said, “The upcoming drilling program will provide the answers we need before we make the decision to start an underground exploration program at Zone 58N.”
Lower Detour gold mineralization is mainly found within the southern portion of an altered feldspar porphyry intrusive characterized by brittle deformation, containing quartz and/or quartz-tourmaline veins with up to 5% pyrite and multiple occurrences of visible gold. The thickness of the feldspar porphyry can exceed 100 m, although individual mineralized lenses are typically up to 30 m in width. The feldspar porphyry narrows to the east and west.
