Lithium Target at Tambourah With Rock Chip Assays Up to 1.47% Li2O

VANCOUVER, British Columbia, Nov. 23, 2017 (GLOBE NEWSWIRE) -- Macarthur Minerals Limited (TSX-V:MMS) (the “Company” or “Macarthur Minerals”) is pleased to announce that it has confirmed lithium mineralisation at the Tambourah Lithium Project (“Tambourah Project”) with rock chip assay results of up to 1.47% Li₂O associated with lepidolite.

David Taplin, Joint CEO and Director of Macarthur Minerals commented:

“Macarthur Minerals is excited about the discovery of a mineralized pegmatite containing up to 1.47% Li₂O, showing excellent potential for lithium at the Tambourah Project. Macarthur Minerals’ next step will be to revisit this area to map the extent of the pegmatite identified during the initial tenement geological reconnaissance program.  Based on these early encouraging results the Company will undertake further geochemical sampling to discover additional pegmatites that host lithium minerals.”

Tambourah Project

The Tambourah Project is located approximately 200 km southeast of Port Hedland and 80 km southwest of Marble Bar in the Pilbara region of Western Australia. The Tambourah Project is approximately 80km south of Pilbara Minerals Limited’s and Altura Mining Limited’s Pilgangoora Lithium Projects.

The Tambourah Project was recognized for having potential for lithium mineralization during a historical review with reports of a Lithium Minedex Record from the Geological Society of WA (“GSWA”).

The Tambourah Project consists of Exploration Licence Application E45/4848 which is expected to be granted in a matter of days.

Assays received from rock chip sampling returned very promising results of up to 1.47% lithium (Li₂O), confirming the presence of lithium bearing pegmatites.

Tambourah Analytical Results

In September, the Company undertook a heliborne reconnaissance field trip across its Hillside Gold Project located approximately 45km to the east. Limited sampling was also undertaken at the Tambourah Project to confirm the presence of lithium noted by the GSWA mapping.

Multiple pegmatite outcrops were observed and a total of four samples were collected from two discrete areas. Lepidolite was observed at both locations separated by 350 m (samples TRC003 and TRC004).

Rock samples were assayed for lithium and associated elements and returned between 0.05% Li₂O and 1.47% Li₂O (Table 1).

Company’s Strategy for Tambourah Project

Macarthur Minerals evaluation of the Tambourah Project is well underway. Further investigation is warranted which will include further rock chip sampling, a soil geochemistry program and mapping.  This will establish the extent of the pegmatites and mineralization.
