Imperial Mining Group Ltd. ("Imperial") is pleased to announce the start of a detailed ground magnetic survey on its 100%-owned Opawica Gold project in the Abitibi region of northwestern Québec. The Opawica gold property is located 20 km east of Desmaraisville and is accessible via Highway 113 from Val d'Or to Chibougamau, Quebec, and by a network of forestry roads.
The program will consist of 71 line-km of detailed ground magnetic surveys. The work will aid in better characterizing the known gold-bearing structures on the property and in identifying zones of intense alteration along the NE-striking Central Gold Zone structure (see Press Release: July 23, 2019), critical factors related to known mineralization on the property. Crews are anticipated to mobilize in mid-October and this work should be completed by the end of October 2019. Abitibi Geophysics of Val d’Or, Quebec was contracted to undertake the survey work.
All results from this program will be integrated into a 3D geological and geophysical model to optimize drill target identification for Winter 2020 diamond drilling.
2019 Opawica Gold Exploration Update
During summer 2019, a geological mapping and geochemical sampling program was completed on the property to better characterize known gold mineralized zones and to establish a structural model for the Central Zone (Figure 2). Zones of strong silica and carbonate alteration and wide NNE and NNW trending structures were encountered during this work. Grab sample values over these areas were found to be highly anomalous in gold, returning up to 550 ppb in silica-carbonate altered felsic to intermediate tuffs containing up to 1% finely disseminated pyrite.
The work focused on the Central structural zone, characterized in historical drilling as a 75-150 m wide deformation and alteration corridor consisting of several shear zones with strong, pervasive carbonate, sericite, and fuchsite alteration. The mineralization is characterized as fine-grained disseminated pyrite and quartz veinlets with gold and silver and occasional visible gold (VG). Previous work on the property identified a 350-m long gold-bearing zone in the central part of the property (Central Zone). Historical drilling from the area returned up to 6.9 g/t gold (Au) over 3.8 m and 87.7 g/t Au over 1.5 m. The Central Zone has never been drill-tested below the 125 m vertical level and is open along strike.
