James Bay Minerals (ASX: JBY) has observed spodumene crystals on the Warhawk pegmatite during a maiden field exploration program at the Aero property within its La Grande project in Canada.
The company employed a portable SciAps LIBS Z-9031 analytical device to test minerals of interest identified in outcrop and rock and channel samples.
The anomalous lithium values which were returned coincided with the identification of the spodumene mineral and highlighted the presence of lithium in the pegmatite.
James Bay said significant organic coverage across the Aero pegmatites — including moss and lichen — made it difficult to visually identify spodumene at surface or to accurately estimate the percentage of lithium mineralisation.
Executive director Andrew Dornan was pleased the company had identified more spodumene at the property.
“The rapid pace of discovery achieved by our exploration team at Aero – where they uncovered a large pegmatite field within two weeks of commencing exploration and have now identified spodumene mineralisation – gives us great confidence that our properties have the key foundations and potential for a major lithium discovery,” he said.
“We are looking forward to receiving assays from this first phase of exploration and advancing this highly prospective property towards drilling.”
Mr Dornan said the mineral on the Warhawk pegmatite appeared light green in colour on weathered surface with crystal habit, cleavage, hardness and positive LIBS readings supporting its identification as spodumene.
Preliminary observations showed generally small crystals of the green mineral identified in outcrop which makes up approximately 2% of the whole rock composition.
Samples were collected for petrography and x-ray diffraction work to confirm the primary lithium-bearing mineral as spodumene and investigate if other lithium minerals are present.
Assay work will be used to determine accurate lithium content which was initially identified by the LIBS device.
Site specific calibration and petrographic analysis will be used to confirm grades and identify all lithium minerals in the pegmatite.
