Presentation Abstract:

Searchlight Resources is a mineral exploration company exclusively focused on the mineral potential of Northern Saskatchewan. It was an early entrant in the evolving field of critical metals exploration in the Athabasca Basin, acquiring extensive interests in properties hosting Rare Earths, Uranium, Copper, Cobalt Vanadium, Cesium and Lithium. Four different deposit models have been recognized as potential economic deposit types including the well-known Rabbit Lake type basement graphitic shear vein style, Rossing style granitic bulk tonnage uranium deposits, Red Bed style Copper-Cobalt-Uranium epigenetic deposits and most importantly Y-Nb-F style pegmatites.

Černý (1991a) proposed that the trace-element signatures of pegmatites fall into two distinct categories, which he referred to as pegmatite families. His two proposed families were LCT (Li-Cs-Ta) and NYF (Nb-Y-F), with the understanding that the signature of the family appears only in the most fractionated members of a group. Recent field investigations and geophysical surveys have led to the recognition of an extensive belt of mineralized pegmatites at Kulyk Lake of the NYF family. Exploration techniques, field prospecting results and deposit models will be discussed.

At Duddridge Lake, a globally significant deposit style is interpreted to be present. Exploration techniques and field results will be presented.

Presenter Bio:

Alf Stewart, MBA, B.Sc Hons Geology

Alf Stewart is an experienced explorationist, mining financier and junior mining executive. Originally from eastern Canada, with an Honours Degree in Geology and extensive field mapping experience in volcanic terranes, he spent five years in BC and the Yukon with Esso Minerals doing grass roots exploration for base metals with a bit of gold mining thrown in as well. After obtaining an MBA at UBC, and earning his spurs in the finance industry working at the Stock Exchange, he joined Canaccord as an investment banker focused on financing mining and oil and gas ventures. After a successful career in finance, he has been working on finding critical mineral deposits in Canada and Australia to power the transition to greener energy and greener transportation for the last ten years. His current interest is the province of Saskatchewan and he is working with a company which has a number of interesting and unconventional critical metals deposits.
