Sage Gold Identifies New Target On Onaman

TORONTO - Sage Gold Inc. reported an update on recently completed exploration work at the company's Onaman volcanogenic massive sulfide (VMS) property, located in northwestern Ontario. The Onaman property is host to several base and precious metal occurrences within the Onaman Volcanic Complex (OVC) including the historical Headway lead-zinc-silver zones and more recently discovered, underlying Lynx copper-silver-gold deposit.
Nigel Lees President and CEO said, "Recent fieldwork and analysis of historical Sage drill core has identified a new and possibly significant VMS target horizon. We have identified a sulfide-bearing sediment within the felsic volcanic pile that may represent an ideal host for VMS mineralization."
Recent exploration work has focused on locating the center of this system and one or more contained horizons within which a pause in volcanism and associated sedimentation may have allowed for an uninterrupted period of metals deposition. Widespread, often intense hydrothermal alteration and subsequent multiple deformation events have complicated the understanding of these rocks, but recently completed detailed geological mapping (lithological-alteration-structural) has significantly advanced Sage's understanding of the evolution and morphology of the OVC and the VMS-related mineralization found within.
Detailed re-logging of core holes drilled during the recent Headway drilling campaign (please refer to the company's news release dated April 4, 2017) and those drilled into and below the uppermost Big Mac massive pyrite-pyrrhotite sulfide zone by Sage in 2008, has enabled Sage geologists to reconstruct the complete volcano-sedimentary and alteration history and zonation of the OVC as well as identify a previously unrecognized target area. Centrally located within an emergent felsic volcanic sequence, or "felsic center", an interval of weakly mineralized sulfidic mudstone has been identified, indicative of a period of quiescence between periods of active volcanism within which sulfides were deposited in seafloor muds and partly replaced and altered the underlying felsic volcanic rocks. Intersected at a depth of over 100 meters below the swamp-covered surface, both ground and borehole geophysics will be required in order to define this significant horizon and delineate vectors to where more significant volumes of sulfides may lie.
Exploration in and around the Onaman property dates back several decades during which time numerous VMS-related occurrences have been documented at various stratigraphic levels of the OVC across its more than 8 kilometer-long partly exposed strike length. These include typical footwall stringer copper-dominant zones documented at several locations such as the Lynx deposit, and typical, overlying lead-zinc-silver dominant zones such as the Headway and nearby Coulee stringer zones. Collectively, they are indicative of the peripheries of a metal-rich volcanic system that was deposited in an active volcano-sedimentary basin.
