The Courageous Lake Project includes two deposits: the Courageous Lake deposit, and the Walsh Lake deposit.
Deposit Types
Courageous Lake deposit
The Courageous Lake deposit is a stratiform series of near-vertical, elongate lenticular mineralized domains hosted in Archean tuffaceous clastic rocks and ash-flow tuff. Gold mineralization is interpreted to be a product of an episodic, epithermal-like, submarine and subaerial, hydrothermal system.
Walsh Lake Deposit
The Walsh Lake zone is contained in quartz vein and silicic alteration within and surrounding shears. Mineralized material mineralogy is dominated by arsenopyrite and free gold. This style of orogenic gold deposit is common in Archean greenstone belts.
Mineralization
Courageous Lake Deposit Mineralization
Since its discovery, several common points have been used to describe the felsic ash tuff (FAT) deposit, including:
• A series of gold zones concentrated in long and narrow bands.
• The deposit is hosted by metasedimentary and metavolcanic rocks.
• Gold concentrations are associated with the introduction of silica, muscovite, and sulphide minerals.
The FAT deposit is located between the north shore of Matthews Lake and the south shore of Courageous Lake. It is made up of at least 13 discrete, steep east-dipping, elongate lenticular zones that vary in thickness from 20 to 125-m-wide. The continuity of these 13 zones has been demons ........
