Morrissey Hill, WA (80%)

Location

Morrissey Hill is situated 200km east of the coastal town of Carnarvon and 50km east of the town of Gascoyne Junction. Road access from Carnarvon is good and is double lane bitumen until a few kilometres east of Gascoyne Junction. Minor gravel roads and station tracks provide good access throughout the area.

History

The area around Morrissey Hill has been the focus of exploration since the early 1900s, firstly for beryl and mica, then uranium in the 1970s, and more recently rare earth elements.  The extensive pegmatite occurrences in the district have rarely been explored for lithium until 2017, when Segue Resources discovered lithium mineralisation at its Reid Well project located immediately to the east of Pure Minerals’ Morrissey Hill project.  Surface rock chip results from Reid Well included 3.77% Li2O, 2.22% Li2O and 1.89% Li2O.

 

Segue has been drilling the Reid Well project since August 2017, where it has intersected pegmatites up to 35m thick.

 

Geology and Mineralisation

The Morrissey Hill Project is prospective for pegmatite hosted Li-U-REE mineralisation associated with intrusive and metamorphic rocks of the Gascoyne Complex. The project area is known for historical mica and beryl mining and substantial pegmatite swarms have been mapped and sampled to date.  However, lithium mineralisation associated with these pegmatites has largely been ignored until recently.

 

Exploration Plans

The Company plans to complete an exploration programme of detailed mapping and geochemical sampling to identify the most prospective intrusive phases and associated pegmatites.

 

In September 2017, Pure Minerals completed a detailed program of soil sampling targeting lithium and tantalum mineralization.  Pure Minerals will assess these results in light of the drilling results from nearby properties to formulate plans going forward.
