Kenorland Minerals Ltd. and Sumitomo Metal Mining Canada Ltd. have been jointly exploring gold deposits in the Frotet property located at approximately 120 kilometres north of Chibougamau in Quebec, Canada. The property covers approximately 393 square kilometres of the Frotet-Evans Archean greenstone belt within the Opatica geological subprovince of Quebec. Frotet-Evans greenstone belt is composed of metamorphic rocks and intrusives hosting Troilus gold deposit located at 5 kilometres north of Frotet property, which produced approximately 2 million ounces of gold in total during the open pit mining operation between 1996 and 2010. Regional till and rock geochemical sampling as well as in-fill till geochemical sampling were conducted between 2018 and 2020, which delineated several anomalous target areas in the property. Regnault area was the most significant target area that showed gold geochemical anomaly extending to NE-SW for over 2.5 kilometres. As the initial program of 2020 field exploration activity, drone aerial magnetic survey and IP survey were conducted in February and March, 2020 to identify drilling targets, which were followed by the initial scout drilling campaign of 7,809 metres in total by 23 diamond drill holes at Regnault area until summer of 2020. As a result of the scout drilling campaign, high grade gold mineralization was identified in several holes including 16.06 g/t Au over 3.76m in hole 20RDD002, 18.43 g/t Au over 11.13m in hole 20RDD007, 33.69 g/t Au over 2.66m in hole 20RDD021A, etc. High grade gold mineralization intersected in Regnault area seems to be associated with disseminated pyrite and trace visible gold within quartz veins and stockworks hosted in diorite to tonalite intrusive complex in most holes. Although there are some similarities in the geological settings, gold mineralization style in Regnault may be different in terms of associated minerals and high gold grade value from Troilus gold deposit in the vicinities, where the main gold mineralization is characterized by disseminated chalcopyrite, pyrite and pyrrhotite in Troilus Diorite with poor quartz veining and thought to be an Archean porphyry-gold style deposit. Moreover, newly conducted in-fill geochemical survey at southwest extension of Regnault area （Regnault South area） unveiled that significant gold geochemical anomaly continues further by 2.5 kilometers. Follow up drilling program is being planned to confirm the geometry of the high grade gold mineralization at Regnault area and to identify new mineralized zones at Regnault South area in 2021.
