Project Geology
The project is underlain predominantly by east-west trending and steeply south to vertically dipping metavolcanic and metasedimentary rocks. Metavolcanic rocks consist of massive and pillowed, locally amygdaloidal, flows of basaltic composition along with related tuffaceous rocks. They are locally intercalated with coarser-grained rocks. Mafic metavolcanic rocks are fault-bounded against domains of metasedimentary rocks closer to the center of the project. The southern metasedimentary panel consists of a polymictic conglomerate and greywackes suggesting affinity with Timiskaming Formation conglomerates in the Timmins (Porcupine) Mining District. Metasedimentary units also contain feldspathic and quartzose sandstone and wacke, siltstone, carbonaceous argillite and hematitic iron formation. Intermediate to mafic intrusions cut the metavolcanic rocks on the southern part of the property and consist of quartz diorite, diorite and gabbro and quartz porphyry.
The average width of the altered and mineralized zone is 30m consisting primarily of mafic metavolcanics and BIF. Historical drill logs suggest a sharp contact between geological units that include mafic metavolcanics, metasediments, gabbros and quartz porphyries. Historical logs also describe visible gold and carbonate veining that consists of sugary and banded quartz with massive pyrrhotite and lesser arsenopyrite and pyrite with chlorite. While no assay certificates exist for this old drilling the surface samples of up to 21 g/t gold taken by Riverside suggest high grade gold is present. This historical work was not conducted to modern NI 43-101 standards and cannot be relied upon but is included here to indicate why Riverside was working and sampling in this area. The old high-grade results will need to be verified using modern technologies and reporting methods.
Gold is commonly enriched in intensely altered rocks adjacent to or within quartz-carbonate veins and veinlets as is found in orogenic deposits. Several of the historical drill logs document high grade intercepts similar to those documented at the Leitch Gold Mine to the west at Beardmore.
