VANCOUVER, British Columbia, Aug. 31, 2018 (GLOBE NEWSWIRE) -- Macarthur Minerals Limited (TSX-V: MMS) (the “Company” or “Macarthur Minerals”) is pleased to announce that it has completed the second phase of a stream sediment sampling program at its Bonnie Scot Project in the Pilbara region of Western Australia (“Bonnie Scot”). The results showed a geochemical cluster of anomalous gold up to 45.9 parts per billion (“ppb”) and consistent with the previous survey.

Mr Cameron McCall, Executive Chairman of Macarthur Minerals commented: “ The Bonnie Scot Project is developing well with a solid geochemical signature delineating a prospective gold target. The geological team will now concentrate exploration efforts across this target to assess the potential for gold mineralisation.”

Stream Sediment Sampling

The Phase 1 sampling program, previously reported on June 13, 2018 concentrated on the contact of the Mount Roe Basalt as a target for conglomerate hosted gold. Results of that survey identified a gold anomaly distal to the contact zone and concentrated on the North Shaw Tonalite. The Phase 2 survey was expanded to cover drainage courses previously not sampled.

The Phase 2 survey collected a further 53 stream sediment samples across the north western area of the tenement and included follow-up sampling near the previously identified gold anomaly.

Samples were submitted for multi-element analysis with results revealing anomalous gold in close proximity to the previously identified gold anomaly. The original anomaly was known from a cluster of eight samples recorded over a radius of approximately 40m. The current program extends the anomalous zone by approximately 300m to the south and west with gold assays up to 113 ppb ( Figure 1 ).

This area in the north west of the tenement was previously considered prospective for gold from a historical rock chip sampling program with values recorded up to 3.5 g/t Au. The stream sediment results from both programs support this view and warrant further exploration. The Company is currently preparing a program to map the geology across the identified anomaly.

Bonnie Scot

The Bonnie Scot project (E45/4764) is located approximately 42 km west-southwest of Marble Bar and 265 km east-south-east of Karratha, in the Pilbara region of Western Australia.

The Bonnie Scot project is ideally situated adjacent to Macarthur Mineral’s Exploration Licences E45/4779 and E45/4732 which are part of the Company’s farm-in deal with Artemis Resources Limited (“Artemis”). The Bonnie Scot project is also in close proximity to areas owned by Novo Resources Limited and the Creasy Group projects that are currently being explored for conglomerate hosted gold.

Geological Survey of Western Australia (GSWA) mapping across the tenement shows areas of the Mt Roe Basalt which is known to overlie the conglomerate gold horizon at Artemis’ Purdy’s Reward. Beds of auriferous (gold containing) conglomerate up to 2 m thick at the base of the Mt Roe Basalt have been worked at the Just-In-Time and Tassy Queen mines located within 10 km of Macarthur Minerals’ tenements and in close proximity to ground held by Novo Resources Limited and Creasy Group.
