Project Description
Main objectives:
This project aims to produce a new geological map with marginal notes for the Brunne Lake area which was entirely burn during a 2010 forest fire. The newly revealed exposures will allow to significantly update the geological map for the area which was last mapped by the GSC in the early 1950`s. This project will provide a better understanding of the stratigraphy, tectonic evolution and geological setting of gold mineralization of the Brunne Lake area.
Methodology:
The project will include systematic 1:10 000 scale geological mapping of volcanic and volcaniclastic rocks. The various granitic intrusions will be mapped at a 1:20 000 scale. In addition, detailed lithological and structural mapping will focus on known gold mineralization occurrences. To complement geological fieldwork, focused lithogeochemistry and Sm-Nd isotopic analyses will be obtained from the various rock units. Drill core from selected drill holes intersecting mineralized zones will be examined in details in order to better understand the geological setting of gold mineralization.
Benefits:
The new 1:10 000 scale geological map will significantly improve our knowledge of the stratigraphy, unit distribution and structural geology of this poorly understood package of volcanic rocks. The results from geological mapping will be complemented by geochemical analysis and isotopic data in order to establish the geochemical affinity of the volcanic assemblage and its tectonic setting. The project also aims to provide a better understanding of the nature and controls of gold mineralization found within the Brunne Lake area and to provide exploration companies with new exploration guidelines.
