iMetal cautions investors the grab samples are selective and may not necessarily be representative of the showing as a whole.
'We have been anxious to get the mechanical trenching program underway at the key target areas of the Gowganda West property, to define targets for drilling in the upcoming late summer drill program,' commented iMetal President & CEO
Zone 1 is associated with Timiskaming type metasedimentary rocks comprising siltstone, sandstone and predominately conglomerate. Gold mineralization is found where conglomerate transitions into finer grained rock types. The conglomerate contains clasts of jasper rich, banded iron formation and is highly magnetic. In addition, the conglomerate contains significant amounts of pyrite, resulting in the unit showing as strongly conductive in induced polarization surveys. The 2018 airborne mag and 2019 IP surveys have allowed mapping of the conglomerate and its boundaries. The boundaries will be the focus of trenching programs.
Trenching will include stripping older exposures cleared in recent decades where the bedrock shows potassic alteration and silica flooding. Trenching will expose this area over a 50m length whereby field crews can use diamond blade saws to take continuous samples over the entire mineralized width enabling geologists to evaluate the extend of the mineralized system and establish the best drill targets. Presently the company believes gold mineralization is associated with narrow, quartz-carbonate-pyrite veins hosted within wider zones of ankerite-albite-silica-sericite alteration and variable amounts of fine-grained, disseminated pyrite. The work now underway should provide more geological context and better information on the nature and orientation of the mineralization.
Zone 3 similarly is hosted in metasedimentary rocks; however, the mineralization is oriented northeast-southwest and dips westward. iMetal has planned 3 trenches over a 200m strike distance to look at the continuity and test the grades in this area. Recent sampling returned stellar grades up to 67 g/t gold in this area. Trenching would hopefully show these grades to extend northeastward.
