Macarthur’s Joint Venture Partner Fe Limited Releases Hillside Copper and Gold Results and Discovers New Manganese Prospect up to 59.4% MnO


VANCOUVER, British Columbia, Oct. 09, 2019 (GLOBE NEWSWIRE) -- Macarthur Minerals Limited (TSX-V: MMS) (OTCQB: MMSDF) (the “Company” or “Macarthur”) is pleased to announce that its Joint Venture Partner Fe Limited (“FEL”), has released further significant  copper and gold assays including a new  manganese oxide area sample recording 59.4% MnO result from a recent field trip to the Hillside Project in the Pilbara Region of Western Australia. 

Macarthur Lithium Pty Ltd (“MLi”), a wholly owned subsidiary of Macarthur entered into an exclusive option agreement (“Option Agreement”) with FEL as announced on May 14, 2019, to earn up to 75% in its Pilbara lithium and gold projects.

Highlights:

  • High grade copper, gold, silver and base metals assays received from outcrop sampling of Gossan over a 14km strike.
  • Newly discovered manganese deposit in sub parallel outcrop to the gossan line.
  • Significant results include:
    • HS0014:     1.2ppm Au, 18.8% Cu, 77ppm Ag, 0.17% Zn, 0.057% Co
    • HS0021:     0.77ppm Au, 3.7% Cu, 187ppm Ag, 0.5% Zn, 0.06% Co
    • HS0023:     1.06ppm Au, 13.9% Cu, 79ppm Ag, 0.44% Zn,
    • HS0024:     0.31ppm Au, 4.5% Cu, 76ppm Ag, 0.35% Zn, 0.05% Co
    • HS0027:     0.28ppm Au, 1.3%Cu, 14ppm Ag, 0.17% Zn, 0.04% Co

    • HS0031:     0.83ppm Au, 7.2% Cu, 78ppm Ag, 0.93% Zn, 0.095% Co
    • HS0033:     59.4% MnO (>46% Mn)
  • Drilling planned and ready for mobilisation in late October (pending approvals)

Cameron McCall, Executive Chairman of Macarthur Minerals commented;

We are pleased to provide an update on the work completed since the Joint Venture between Macarthur and Fe Limited was entered into on May 14, 2019.  FEL’s exploration activities have been focused on the Company’s previously underexplored Pilbara lithium and gold areas and to date, the results have been very encouraging with numerous high-grade results in the Hillside and Strelley Project areas.  FEL is currently in the process of planning a drilling program with the areas shaping up to host multiple attractive and untested prospects.”

As previously announced by the Company on August 23, 2019, samples collected by FEL’s geological team from the Hillside Project returned strongly anomalous grades for base metals and gold from several locations.  In early September FEL conducted follow-up reconnaissance to the Joint Venture tenements, concentrating on the Hillside Project (E45/4824 and E45/4685) and the south-eastern area of the Strelley Project (E45/4735) looking for extensions to the base metals deposit of VentureX.

The focus at Hillside was to map and sample the partially outcropping gossan line and sample outcropping quartz reefs known to host gold mineralisation (from prospector reports).

The gossan line was traced over a 14km strike length with remnant outcrop identified at regular intervals along strike. Much of the area between outcrop presented as leached saprolite in accordance with the typical gossan model (Figure 1).

A total of 36 rock chip samples were collected including 15 from outcropping gossan with several samples containing visible copper minerals such as malachite (e.g. Figure 4). Remaining samples were collected from quartz outcrops, many of which returned strongly anomalous gold grades.

The assay results are highly encouraging with 8 samples returning copper values over 1% with a peak of 18.8% and often accompanied with elevated gold, silver and zinc values (+/- cobalt) (Table2).

Of considerable interest was an assay result of 59.4% MnO (46% Mn) from a sample collected from outcrop of a newly discovered oxide horizon. By comparison, Consolidated Minerals’ Woodie Woodie manganese deposit has a resource grade averaging 31.4% Mn. This prospect will be followed up in due course,

Sample locations are presented in Table 1 and Figure 2 with assay results in Table 2. Examples of select samples are shown in Figures 3 – 7.  

A drilling program has been planned by FEL targeting depth extensions of the gossanous mineralisation with initial shallow angled holes to intercept the interpreted dip as guided by the local structural setting. Some deeper holes are expected to be drilled depending on what is discovered in the field.  The drilling program is anticipated to begin in late October pending receipt of necessary approvals.
