Canadian-focused lithium explorer James Bay Minerals has completed a helicopter-borne magnetic and spectrometric survey across its La Grande project in the country’s Istchee-James Bay region.
The company engaged Prospectair to acquire high-resolution magnetic and spectrometric data across the Aqua, Aero and Joule prospects, located along trend from the Corvette deposit where Patriot Battery Metals has a maiden inferred resource of 109.2 million tonnes grading 1.42% lithium oxide and 160 parts per million tantalum pentoxide (at a 0.40% lithium oxide cut-off).
The magnetic and spectrometric data will be used to analyse and identify various structural features across the prospects.
Any radiometric lineament lining-up with narrow topographic highs or magnetic lows (or a break in magnetic signal) is expected to produce a high potential target.
Follow-up targets
James Bay said the data generated would be critical in determining the direction in which the La Grande pegmatites plunge undercover and identifying follow-up targets for a drilling program in the new year.
Across the remainder of this year, the company’s exploration team will conduct desktop studies using all data generated from the maiden field program including LiDAR, high-resolution photography, field mapping, sampling and geophysical surveys.
La Grande is a prospective lithium property located along trend from Winsome Resources’Cancet project and Patriot’s world-class CV5 deposit.
Pegmatite dykes
Last week, James Bay announced it had identified five large outcropping pegmatite dykes at the highly-prospective Aqua prospect.
They were discovered during helicopter surveys at the south-east portion of Aero where the company had previously identified a large and continuous fractionated pegmatite field covering a corridor of more than 3 kilometres in length.
Aqua comprises 63 continuous claims over 32.25 square kilometres.
The geology of the area touches the Archean sub-provinces of La Grande, Bienville and Opinaca and includes gabbro dykes and a Proterozoic arenitic basin.
Regional faults which transverse the property are host to the La Grande Greenstones which are considered highly-prospective for lithium-caesium-tantalum (LCT) pegmatites.
