The Frotet Project is a 55,921 ha district scale exploration opportunity within the vastly under-explored Frotet-Evans Archean greenstone belt within the Opatica geological sub-province of Quebec. The property is adjacent to the past-producing Troilus Au-Cu mine and covers several major deformation zones associated with known orogenic gold prospects, as well as stratigraphy hosting VMS deposits elsewhere in the belt.
Orogenic Au, VMS
Location and Access
The project is located 100 kilometers to the north of Chibougamau, Quebec. Favorable infrastructure exists in the project area with an extensive forestry road network as well as the Route du Nord cutting across the southwestern corner of the property. A power transmission line also crosses through the property which supplied power to the past producing Troilus mine.
Geology and Mineralization
The Archean Frotet-Evans greenstone belt (2793-2755 Ma) is comprised of a volcanic package dominated by mafic to felsic metavolcanic rocks. The lower volcanic sequences are mafic dominant, composed of basaltic komatiites and high magnesium to iron tholeiites, while the upper sequences are generally intermediate to felsic in composition. Mafic intrusions are volumetrically abundant throughout the stratigraphic sequence, generally present as differentiated sills contemporaneous with the volcanic strata. Thin horizons of sedimentary rocks, consisting of argillites, greywackes and minor conglomerates are intercalated throughout the stratigraphy. Structurally, the volcanic sequences have been strongly deformed as a result of at least two major deformation events (2720-2690 Ma and 2690-2680 Ma) marked by several regional-scale folds dominating the core of the belt, and numerous major NE trending structures transecting the property. A significant number of small, high grade gold-quartz veins have been discovered across the belt, as well as multiple Zn-Cu-Ag-Au VMS deposits occurring in the southern portions of the belt. Together, the structural architecture combined with favorable lithological constraints and proven fertility indicate the Frotet-Evans Project is highly prospective for significant orogenic gold and VMS mineralization.
Limited systematic historic exploration has been completed across Kenorland’s claim package. The discovery of copper-nickel bearing float samples in 1958 led to a staking rush, and subsequent discovery of many of the VMS deposits to the south of the current property. The NE trending structural corridor and Troilus Au-Cu deposit were discovered in the mid 1980’s as the result of reconnaissance exploration programs by Kerr Addison (lake sediment and soil sampling, and prospecting) concentrated along the western half of the Frotet-Evans greenstone belt. The area has seen very little follow-up exploration since the 1980’s, but modern geophysical surveys have added to the structural understanding of the Frotet-Evans greenstone belt architecture. As the project area is extensively covered with glacial till and many small lakes, Kenorland’s objective is to apply a systematic exploration approach to the Frotet-Evans Project; integrating modern geochemical and geophysical datasets to the current geological understanding, to identify high level targets for further exploration.
