New Age Metals Inc. (TSXV: NAM; OTCQB: NMTLF) has identified a number of new targets from the results of multiple high-resolution UAV-borne magnetic surveys in Manitoba, Canada.
The surveys were completed in 2021 by EarthEx Geophysical Solutions of Selkirk, Manitoba over the company’s Lithman West, Lithman East, Lithman North, Lithium Two, and Cat Lake Properties.
The surveys were completed to provide highly detailed magnetic maps to aid in the exploration, geological mapping, and drill-targeting of these highly prospective target areas. The surveys were successful in identifying multiple prospective trends that enhance the potential for additional discoveries.
The 2021 geophysical programmes in Manitoba were co-funded by a grant that was received from the Manitoba Chamber of Commerce’s, Manitoba Mineral Development Fund (MMDF) that totalled C$46,000.
The results of the high-resolution UAV-borne magnetic survey in combination with other exploration techniques will be valuable in defining additional areas with high potential to host lithium bearing pegmatites and advance the company’s projects. We look forward to
conducting follow up surface exploration to ground truth these geophysical targets in 2022,” Chairman and CEO, Harry Barr, said.
The company’s properties in SE Manitoba are strategically situated within the Winnipeg River Pegmatite Field, which hosts the world-class Tanco Pegmatite that has been mined for Tantalum, Cesium and Spodumene (one of the primary Lithium minerals) in varying capacities, since 1969.
Lithium pegmatites are known to express anomalously low magnetic susceptibility readings and are generally constrained to regional-scale geological structures. The advent of the high-resolution low-flying UAV magnetometric surveying system used by EarthEx is an efficient way to help identify structural trends and areas of low magnetic susceptibility that may correlate with lithium-bearing pegmatites. This in turn, will aid in defining exploration targets as well as delineating the extent of these types of deposits both at and below surface. Five grids were flown with a total of 1308 line-km over an area of 28.24 sq. km.
Mr Barr said egmatites often occur in semi-discontinuous swarms and can be concentrated along structural trends and geological boundaries. The completed surveys have identified multiple prospective linear features with strike lengths ranging from 500 m up to three km on multiple properties which exhibit low magnetic responses with favourable orientations. Follow-up mapping and surface sampling will be planned to ground truth these anomalies on the Lithman West, Lithman East, and Cat Lake projects.
The Lithium Two property survey results identified multiple offsetting features and potential structural breaks in the magnetic data cutting the regional geological trends. These structures coincide with the orientation of known high grade lithium bearing pegmatitic dikes (Eagle Pegmatite) and can be used to vector future drill targeting. This data may allow us to extend the strike length of known mineralisation where outcrop is not exposed on surface and explore for parallel trends both north and south of the Eagle Pegmatite.
A one-week follow-up program in the fall of 2021 found unmapped pegmatites associated with multiple structural features identified in the magnetic survey results. This confirmed the value of this data as an exploration tool.
A more comprehensive programme of mapping and surface sampling is being planned for the upcoming summer to follow-up the results of the UAV-borne magnetic surveys on the five survey grids.
