Thunderbird
Project Overview
The Project lies in the Waddy Lake district in northern Saskatchewan, approximately 130 km by air northeast of La Ronge, Saskatchewan. The Project area comprises the Tower Lake, Memorial, Birch Crossing and Niko-Kaslo properties. The Thunderbird project area is located in the northern portion of the Central Metavolcanic Belt of the La Ronge Domain, a granite-greenstone belt in the Saskatchewan segment of the Trans-Hudson Orogen.
At Tower East, gold mineralization occurs in the hanging wall rocks at the Tower East deposit as very fine-grained disseminated, “free” metallic gold, and as very fine grains contained within individual pyrite grains. Gold was introduced during a hydrothermal sulphidic-potassic alteration event. The steeply south-dipping Byers Fault also forms the most prominent structural feature in the Birch Crossing area. Here, the fault demarcates the contact between a relatively homogenous diorite intrusive body to the south (hanging wall) and a mixture of pyroclastic and porphyritic dacitic rocks in the footwall of the fault to the north.
At Birch Crossing, gold mineralization, accompanied by minor chalcopyrite, was likely introduced in an epigenetic event related to hydrothermal sulphidic-potassic alteration. Brittle fracturing was an important precursor to the main mineralizing event, allowing passage of hydrothermal fluids and the injection of hydrothermal quartz veins. Most high-grade gold mineralization at Birch Crossing is found within hydrothermal quartz veins which have formed at the contact between intrusive and volcanic rocks.
At Memorial, gold is underlain by of metavolcanic and associated metasedimentary rocks which strike regionally from northeast to southwest. The volcanic
sequence is dominated by massive to pillowed mafic flows and lesser intermediate to felsic flows and sediments. Sulfide-facies iron formation is common in the sequence and contains primary pyrite and/or pyrrhotite with occasional traces of chalcopyrite.
