Pioneer 100%

The Phillips River Lithium Project is located approximately 100 km east of the Mt Cattlin Lithium Mine, Ravensthorpe, in Western Australia. The project comprises three exploration licence applications that cover approximately 340 km² that are considered prospective for lithium spodumene-bearing pegmatites.

Lithium Targets Identified Using Geoscience Australia Dataset

The Project was generated through interrogating the Geoscience Australia ‘National Geochemical Survey of Australia: The Geochemical Atlas of Australia: Dataset’ (de Caritat et al, 2011) which included a sample taken from the Lort River catchment in south Western Australia that contained the highest lithium value from a stream sediment sample in Australia.

Roadside sampling ‘upstream’ of the Lort River lithium anomaly, completed by a competitor exploration company (Fletcher and Howard, 2010; Eddison and Fairall, 2012), included assays for lithium as part of a broader suite of elements targeting gold. When processed, this information indicated 2 standout lithium anomalies supported by modified pegmatite PEG-4 index values (Smith et al, 1987), and a number of other lithium anomalies which are considered elevated and warrant further investigation.

This pegging is consistent with the Company’s strategy that was announced in its release of 15 March, 2016 and further expands its asset portfolio of key demand‐driven commodities – adding additional lithium properties to its high grade gold assets and nickel properties in Western Australia. The Company’s commitment to these projects remains unchanged and it will provide details of the next phase of exploration initiatives in due course.

Close to Established Infrastructure

The Project is located approximately mid-way between Ravensthorpe and Esperance in the Great Southern of Western Australia. Tenements are readily accessible through a network of main and regional roads with water, power, and a skilled work force available close-by. The Port of Esperance is approximately 60 km away.

Exploration Strategy in a Rare-Element Mineral Field

The Project is considered prospective for rare-element granitic pegmatites of the Lithium-Caesium-Tantalum (LCT) geochemical family. These are the type of pegmatites that have been intersected in drilling at the Company’s optioned Mavis Lithium Project, located in Ontario, Canada.

Pegmatite is a reasonably common igneous plutonic rock of variable texture and crystal size, composed of common granite minerals such as quartz, feldspar and micas, but less commonly with economically important minerals (the LCT pegmatites) containing elements such as lithium (in spodumene), tantalum, niobium, tin and tungsten.

Genetically, LCT pegmatites have been linked to the emplacement of peraluminous, S-type granites, and distinguishing these from barren (such as I-type) granites is a critical step in the exploration for lithium of this genesis (see Glossary for more details).

The largest known LCT pegmatites in Western Australia include those at Greenbushes (lithium, tin and tantalum), Pilgangoora and Wodgina (lithium, tin and tantalum), Mt Marion (lithium), Bald Hill (tantalum); and in the immediate area, the Mt Cattlin (lithium and tantalum) Deposit.

Work Programs

Following the grant of the tenements, expected during the third quarter 2016, work programs are likely to include:

  • Further multi-element geochemistry to constrain what are presently large, open targets.
  • Aeromagnetic surveys. Pegmatites are much less magnetic when compared to the host mafic volcanic country rocks.
  • Mapping within resultant targets. Much of the tenement area has been cleared for cropping, making access easy.
  • Resultant drilling.

Pioneer’s current program of lithium and gold project acquisitions; and associated exploration programs in Australia will be undertaken concurrently with the commencement of field exploration activities at the Mavis Lithium Project in Ontario, Canada, where soil and rock geochemistry, mapping and a ground magnetic survey, and a diamond drilling program are currently being planned ahead of a commencement date in May 2016.

Drilling is also planned for the Company’s Acra Gold Project, to further test new targets identified by drilling in 2015 at the Deep River and Kalpini West prospects, and infill and extensional drilling at the Kalpini South gold deposit.
