Macarthur’s Retention of Pilbara Tenements Provides Opportunity to Explore for New Partners

Macarthur’s Retention of Pilbara Tenements Provides Opportunity to Explore for New Partners

VANCOUVER, British Columbia, Sept. 21, 2020 (GLOBE NEWSWIRE) — Macarthur Minerals Limited (ASX: MIO) (TSX-V: MMS) (OTCQB: MMSDF) (the “Company” or “Macarthur”) announced last week that it is retaining 100% of its tenements in the Pilbara region of Western Australia following the end of the Option Agreement (“Agreement”) entered into with Fe Limited (“FEL”) in 2019. The tenements, held by the Company’s wholly owned subsidiary Macarthur Lithium Pty Limited (“MLi”), include the Hillside, Panorama, Strelley’s Gorge and Tambourah projects. These projects are considered prospective for gold, copper, lithium and iron.
Following last weeks’ announcement (see release here) the Company has already received a number of new enquiries regarding future joint venture opportunities.  This early interest augurs well for the future of the Pilbara projects and the value potential for Macarthur’s shareholders. Macarthur continues to primarily focus its resources on bringing its flagship Lake Giles Iron Project into production and is seeking options to advance the Pilbara tenements to realise shareholder value without incurring material expenditure or significant management time.The terminated Agreement with FEL has delivered value to Macarthur. Macarthur retains 26,666,667 FEL shares, which were issued following FEL’s election to exercise the option for an earn in. FEL has also contributed to exploration expenditure over the last 12 months including an initial drilling program at the Hillside project with encouraging results from this first phase drilling program as reported on 10 February 2020 (see FEL release dated 10 February 2020 here).Over the last 12 months, the program of exploration that has been undertaken across the Pilbara tenement portfolio has provided very positive early results for a range of base and precious metals. A summary of the previously reported prospectivity of the tenement portfolio is outlined below:Hillside Gold and Copper ProjectThe Hillside Gold and Copper Project (“Hillside”) includes four tenements covering 400 km2 located approximately 185 km south east of Port Hedland and 50 km south west of Marble Bar. The project is situated in an area of highly prospective greenstone terrane that includes the Apex and Euro Basalts and other units of the Warrawoona group. Numerous surface gold and copper rock chip occurrences suggests this area is highly prospective for gold and copper mineralisation.   The Hillside tenements surround the mining lease of the historic Edelwiess gold mine. A limited drilling program consisting of six rotary percussion (“RC”) holes conducted by Metana Minerals N.L in 1980 intersected gold mineralisation associated with quartz veins. Gold was recorded in three holes with an average grade of approximately 12 g/t Au and a maximum of 25.83 Au g/t. In addition, sampling along a discontinuous outcropping gossan over a strike of 18 km, showed high potential for copper mineralisation. A total of 20 results yielded above 1,000 ppm Cu to a maximum of 7.8% Cu.Whilst the Hillside area has previously been explored by various companies for gold, copper, zinc and lead, limited drilling has been conducted on the Hillside tenements. As previously reported by FEL on 9 October 2019 (see FEL release dated 9 October 2020 here), numerous surface gold and copper rock chip occurrences suggests a potential for this area to be highly prospective for gold and copper mineralisation.The gossan line was traced over a 14km strike length with remnant outcrop identified at regular intervals along strike. A total of 36 rock chip samples were collected including 15 from outcropping gossan with several samples containing visible copper minerals such as malachite. Remaining samples were collected from quartz outcrops, many of which returned strongly anomalous gold grades.The assay results are highly encouraging with eight samples returning copper values over 1% with a peak of 18.8% Cu and often accompanied with elevated gold, silver and zinc values (+/- cobalt).Exploration at the Hillside Project also discovered high grade manganese mineralisation in sub parallel outcrops to the gossan line sampled above. Rock chips samples returned a maximum of 59.4% MnO (>46% Mn).In November 2019, a drilling program was completed at Hillside which focused on a gossan line and outcropping quartz reefs. Assay results, returned from the laboratory demonstrate support for a mineralised gossan model with down dip extension of mineralised gossan at surface intercepted in three holes with the following results as announced by FEL on 10 February 2020, (see FEL release here).HRC001: 1m @ 0.19% Cu, 230ppm Co, 0.14% Zn, 0.07ppm Au from 28mHRC022: 1m @ 0.74% Cu, 349ppm Co, 0.41% Zn, 0.14ppm Au from 83mHRC036: 1m @ 0.18% Cu, 0.12% Zn from 25m and 1m @0.27% Cu from 40mFurther exploration activities on the Hillside tenements including a fixed loop electromagnetic survey (FLEM) were undertaken in the second quarter of 2020. The survey data is currently being processed and interpreted by Macarthur.
Panorama Gold ProjectThe Panorama Gold Project (“Panorama”) includes three tenements covering 250 km2, located 265 km south-south-east of Karratha and is prospective for lithium and gold hosted within conglomerate. The tenement group contains an extensive area of the Mt Roe Basalt which is the geological member of the Fortescue Group that overlies the conglomerate gold horizon at Artemis Resources’ Purdy’s Reward Project near Karratha, Western Australia.In 2018 the Company conducted stream sediment sampling programs across the Panorama tenements confirming several anomalous sediment values ranging from 13 ppb to 113 ppb Gold.Strelleys Gorge and Tambourah Iron Ore ProjectsMacarthur considers the Strelley’s Gorge and Tambourah tenements prospective for iron ore.In 2019, Macarthur’s then joint venture partner FEL, conducted a reconnaissance trip to the Strelley Project with two samples taken from the outcropping Banded Iron Formation (“BIF”) continuing along strike from the previously mined Abydos iron ore project owned by Atlas Iron. The results, referred to in the FEL release dated 5 September 2019 (see full release here) returned assays of 61.3% Fe and 58.11% Fe.Tambourah Lithium ProjectThe Tambourah Lithium Project is located approximately 200km south east of Port Hedland and 80km south west of Marble Bar. Assays received from rock chip sampling returned very promising results of up to 1.47% lithium (Li2O), confirming the presence of lithium bearing pegmatites.The Company also holds Exploration License E45/5324, which is near its Tambourah Lithium Project in the Pilbara Region of Western Australia. A review of historical data indicates that this area is prospective for nickel-copper-cobalt and platinum group element mineralization.An infographic accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/cbeb0526-3b83-4bca-ad96-df62e872bff3Cameron McCall, Executive Chairman of Macarthur Minerals commented:Macarthur is enthusiastic about the prospectivity of its Pilbara tenement portfolio and is excited to have retained its 100% interest these Projects. This is a positive outcome for the Company.The results of previous exploration and drilling programmes underpin the confidence of the Board and Management in the potential of this ground.The Company is already receiving new enquiries about the potential to venture out the ground. We will seize the opportunity to advance exploration work in the area and identify and work together with the most suited partner to fulfil the potential of these tenements and maximise value for our shareholders.On behalf of the Board of Directors, Mr Cameron McCall, Executive ChairmanFor more information please contact:
