Pioneer Dome Lithium Project
Essential Metals 100%
Essential Metals’ Pioneer Dome Project is a highly prospective, multicommodity project located approximately 130 km south of Kalgoorlie and 200 km north of the port of Esperance. Access is excellent with the Goldfields Highway and Esperance railway, and water and gas pipelines passing through the Project. The Project covers an area of approximately 389 km².
The Project targets the 20 km strike length of the eastern periphery of the Pioneer Dome. The Project was recognised as having potential for lithium mineralisation following a review of historic exploration reports which recorded numerous pegmatite intersections in nickel or gold‐focussed drilling completed since the 1960s. The prospectivity model was further enhanced by colloquial records of lepidolite, tantalite and tourmaline in prospector scale workings, which are some of the characteristic minerals of a zoned pegmatites complex.
The Company has identified over 20 pegmatites. While are number are recognised as not prospective, others have clear ‘LCT’ pegmatite affinities, including the Sinclair Pegmatite (pollucite, petalite, lepidolite, K-feldspar), the Cade and Heller pegmatites (spodumene) and PEG009 (lepidolite).
In June 2019, spodumene was discovered outcropping in the northern area of the Pioneer Dome Project and this location is now known as the Dome North Lithium Project.
Following completion of the first drill programme, in November 2019 a maiden JORC Inferred Resource Estimate was reported of: 8.2Mt @ 1.23% Li₂O (refer ASX release 25 November 2019).
In December 2019, a second drilling programme was completed with the more significant drilling intersections reported (refer ASX release 4 February 2020) as follows:
