Root Bay Lithium Project

The Company owns 100% of the Root Bay lithium project.

The Root Bay lithium project is accessible via local logging roads north of Sioux Lookout and is located approximately 300km north-west of the regional centre of Thunder Bay. The project is strategically located approximately 5km to the east of the recently acquired Root Lake Lithium Project and consists of three claim areas, totalling 720 hectares.

The project was staked by Ardiden as part of its regional exploration focus in and around the Root Bay spodumene-bearing pegmatite structure located in Claim 4282605. The outcropping Root Bay spodumene-bearing pegmatite structure was accidently discovered by a representative of the Ontario Ministry of Northern Development and Mines (“MNDM”) in 2011. 

The newly discovered pegmatite is exposed on the eastern side of a logging road along the prominent ridge that follows the presumed trace of the Lake St. Joseph Fault. The exposed pegmatite is described as hosted by locally pillowed, mafic metavolcanic rocks.

Initial observations by the MDNM states the dyke is characterized by coarse white albite, grey quartz and pale grey-green spodumene crystals up to 10cm long. The outcrop distribution of the pegmatite indicates that the spodumene dyke is perhaps 10m wide at this location along the limited, exposed contact of approximately 60m.

Reconnaissance Exploration and Sampling Program

Ardiden completed an initial reconnaissance exploration and sampling program at the greenfields Root Bay Lithium Project in August 2016.

Ardiden’s geological team cut a 15m channel across the surface of the outcropping pegmatite, collecting 15 samples which were each 1 metre long. The channel samples were logged and sent to Actlabs laboratory in Thunder Bay for analysis under QAQC procedures.

Logging and analysis from the maiden sampling program has confirmed the strong presence of spodumene with lithium mineralisation identified in all of the channel samples and outstanding grades of up 2.54% Li2O returned.

Ardiden considers these initial exploration results to be very encouraging, particularly the presence of a continuous 13m long lithium mineralisation zone across the surface of the primary pegmatite exposure, averaging 1.77% Li2O.

This initial limited mapping and sampling program provided information about the geological and structural formations and confirmed the orientation of the pegmatite exposure as North-South striking.

The next phase of exploration will target the strike and dip continuity of the primary pegmatite structure and allow additional local pegmatite exposures to be mapped and sampled.
