• Helicopter surveys identify 5 large outcropping pegmatites at James Bay Minerals’ Aqua prospect, part of La Grande project in Canada
  • Discovery could be continuation of Fin Resources’ recently discovered pegmatites w/ “abundant spodumene crystals”, 250m from tenement boundary
  • Fieldwork ongoing at Aero prospect, planning underway for further exploration at Aqua


The five, large outcropping pegmatite dykes at James Bay Minerals’ Aqua prospect appears to be a continuation of the spodumene-rich ground identified by Fin Resources in the adjacent tenement.

Newly listed James Bay Minerals (ASX:JBY) has one of the largest lithium portfolios in the James Bay region, covering 224km2 across four projects – the flagship Joule, Aero, Aqua (all part of La Grande) and Troilus to the south.

La Grande has all three key ingredients for massive LCT pegmatites, JBY says, with its:

  • Right age neo-archaen rocks
  • Fertile s-type granites
  • Huge deformation zones

Aqua itself is in a great spot, along trend from Winsome Resources (ASX:WR1) Cancet lithium project and  Patriot Battery Metals’ (ASX:PMT) huge 109.2Mt @ 1.42% Li2O and 160ppm tantalum Corvette deposit.

It is also right next door to Fin Resources (ASX:FIN) Cancet West project, where the explorer recently identified “abundant spodumene crystals within a broad pegmatite outcrop” less than 250m from the tenement boundary.

Recent helicopter surveys of James Bay’s Aqua property have now identified five large outcropping pegmatite dykes, interpreted to be a continuation of Fin’s spodumene-rich pegmatites.

“It’s great to see our neighbour Fin Resources make a discovery of a significant pegmatite outcrop containing large spodumene crystals at surface on its Cancet West property, immediately adjacent to the Aqua boundary,” JBY MD Andrew Dornan says.

“It’s extremely encouraging given we have identified multiple large pegmatites which we believe connect with Fin’s discovery. Our theory on why we chose these properties continues to be validated.”

Next steps

The company says Fin’s recent results have elevated the Aqua project’s prospectivity, with planning underway for a field program to fully investigate the pegmatite outcrops delineated from the air.

“It is highly encouraging to have identified large pegmatite ridges several metres above the surrounding ground running in parallel within deformation corridors across both the Aero and Aqua properties, with the discovery of lithium mineralisation on neighbouring leases providing further strong targets for exploration going forward.”

JBYs field program continues to focus on the south-eastern portion of the Aero property, where a large continuous fractionated pegmatite field covering a corridor of >3km has been discovered.
