Pioneer Dome Lithium-Caesium-Tantalum Project

Pioneer has discovered pegmatite-hosted lithium mineralisation in rock chip samples at its 100%-held Pioneer Dome Project. The Project, near Norseman in Western Australia, is located 130 km south of Kalgoorlie. The Project is situated 200 km north of the Port of Esperance with access via the Goldfields Highway. Water and gas pipelines also pass through the Project. The Project covers an area of approximately 341 km² comprising six exploration licences plus a mining lease which has been pegged over the Sinclair Caesium Zone.

At least 13 clusters of pegmatites, including LCT pegmatites, have been identified along a 20 km strike length. Approximately 7000 soil samples have been used to identify 9 priority and 15 mid-rank targets. Mapping and additional sampling required to generate drill targets. The inaugural 5000m RC programme at the end of 2016, identified both high grade Lithium and Caesium. The Project demonstrates strong potential for the discovery of a significant spodumene deposit and will be a focus for future drilling – such a discovery would be a major value driver. The Company transitioned to miner, with the successful stage one mining campaign December 2018-January 2019 at the high grade Sinclair Caesium deposit Sinclair Zone.

Mavis Lake Lithium Project

The Mavis Lithium Project is situated 19 km east of Dryden, Ontario, Canada. The Project is well located to relevant infrastructure. Drilling at the Mavis Lake Spodumene Project in Canada demonstrated that the system is well mineralised with ‘best to date’ drilling intersections returned. An amendment to the Mavis Lake JV documentation saw the Company complete its 51% project equity earn-in, coupled to the relinquishment of its Raleigh Project interest.

Donelly Lithium Project

The Donelly Lithium Project is located in the world class Greenbushes Mineral Field in south-west Western Australia. It extends from 12 km to 60 km southwest of the world class Greenbushes Lithium Mine, and comprises two exploration licence applications (E70/4826 and E70/4829) covering a total area of 220 km². The Donnelly Project is considered prospective for lithium contained in spodumene-bearing pegmatites of the Lithium-Caesium-Tantalum (LCT) geochemical family.

Phillips River Lithium Project

The 100%-held 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. Initial work will be to undertake detailed soil geochemistry in the areas of very anomalous lithium results returned from roadside sampling completed by a previous tenement holder.

Bogadi Lithium Clay Project

The Bogadi Project was a conceptual target for a large unconventional lithium-in-clay deposit. 5 drill holes were completed, co-funded under the Western Australian State government’s Exploration Incentive Scheme. No significant results have been returned, and no further work is planned.
