The RLX North and RLX South property package is located within the Red Lake Greenstone Belt of Northwestern Ontario. Collectively the RLX North and RLX South properties form a contiguous land package of over 10,000 hectares surrounding Great Bear Resources’ Sobel property.
The primary distinction between the two properties (RLX North and RLX South) is with the interpreted geology underlying each, with RLX North interpreted to be underlain primarily by the 2.96-2.99 Ga Balmer Assemblage, and RLX South interpreted to be underlain primarily by the 2.73-2.75 Ga Confederation Assemblage. The contact between these two metavolcanic packages is highly prospective for economic deposits of gold in the Red Lake mining camp. The majority of historic gold production from the district has been mined from within a few hundred meters of this important geological contact, making it a high priority exploration target.
The exact boundaries and the contact between the two metavolcanic packages, and the surrounding felsic intrusives are not accurately mapped owing to the presence of thick overburden. The lack of rock exposure (less than 1%) has also resulted in limited historical exploration, and the property is underexplored in comparison to other areas of favourable stratigraphy within the Red Lake Greenstone Belt. This represents an exploration opportunity, to answer previously unanswered questions about the underlying geology of the area.
While historic exploration has been limited, particularly in the areas of preliminary interest on the property, sufficient exploration has been done to provide some useful data to be reinterpreted. Selco diamond drill hole 160-5-1 drilled in 1980, for example, was collared in the northeastern portion of the RLX North property. Based on government geological maps, this drill hole was collared several hundred meters into the surrounding felsic intrusives. However, an examination of the drill core logs reveals that the drill hole remained in metavolcanics or metasediments for its entire 300 ft length. This hole was interesting and may warrant follow-up work because the top portion of the hole, which is almost exclusively mafic-ultramafic and metasedimentary, is consistent with lithology typical of the Balmer Assemblage, while the lower portion of the hole, which is almost exclusively felsic to intermediate, is consistent with lithology typical of the Confederation Assemblage. It is possible that this hole may have transected the Balmer-Confederation contact in an area previously interpreted to be felsic intrusives.
Based on mapped geology and regional geophysical surveys, the project area can be interpreted to be a possible extension of the geology and structures hosting Evolution Mining’s Red Lake Gold Mines which are located approximately 10-17 km to the northwest of the RLX South and RLX North properties, respectively. Historic geophysical surveys have identified the possible presence of D2 folds and east plunging anticlines on property, which may be important structural controls on mineralization.
