INFINITY MINING IPO SPIN-OUT UPDATE: Tenement transfer to secure future iron ore extension strategy in the Pilbara for Macarthur

INFINITY MINING IPO SPIN-OUT UPDATE: Tenement transfer to secure future iron ore extension strategy in the Pilbara for Macarthur

VANCOUVER, British Columbia, Sept. 09, 2021 (GLOBE NEWSWIRE) — Macarthur Minerals Limited (TSX-V: MMS) (ASX: MIO) (OTCQB: MMSDF) (the Company or Macarthur) is pleased to announce that the Company’s Pilbara iron ore tenements, (currently held by wholly-owned subsidiary Infinity Mining Limited (Infinity), previously named Macarthur Lithium Pty Ltd), will remain in the Macarthur Group. An intra-group tenement transfer agreement to be finalised prior to the planned listing of Infinity later this year will preserve Macarthur’s ability to pursue a future iron ore extension strategy in the Pilbara.

Highlights

  • Tenement transfer agreement to keep Pilbara iron ore tenements within Macarthur Group.
  • Infinity to retain non-iron ore rights in Pilbara tenements following completion of its planned ASX listing later this year.
  • Transfer will allow all prospective tenements in the Pilbara to be appropriately resourced and drive value through exploration, back to shareholders.
  • Transfer preserves a future Pilbara iron ore extension strategy for Macarthur, with potential to grow future value beyond on the Company’s flagship Lake Giles Iron Project.
  • Macarthur will seek to transact with a partner on the Pilbara tenements to enable it to maintain its current focus and resources on the development of its flagship Lake Giles hematite and magnetite projects.

Tenement Transfer Agreement

A tenement transfer agreement (Agreement), to be finalised prior to the planned Infinity ASX listing, will see the Company’s Strelley Gorge and Tambourah tenements in the Pilbara transferred into Macarthur’s wholly owned subsidiary, Macarthur Iron Ore Pty Ltd. The Agreement will enable the Company to pursue a future iron ore extension strategy in the Pilbara.

Whilst Macarthur Iron Ore Pty Ltd will become the registered holder of the tenements, as the Pilbara tenements are also prospective for copper, gold, nickel and lithium, following completion of the transfer, Infinity will retain all non-iron ore mineral rights in the tenements.

Background to Pilbara Iron Ore Tenements

The tenements that will be transferred under the Agreement are the Strelley Gorge (E45/4735) and Tambourah (E45/5324) tenements in the Pilbara region of Western Australia, covering a combined area of approximately 616km2. The Strelley Gorge tenement is prospective for DSO iron ore and is located immediately adjacent to the Abydos iron ore project that has been mined by Atlas Iron Limited (Atlas Iron). The Tambourah tenement is also prospective for iron ore, with a 5km strike length of the Pincunah banded iron member, that hosts Atlas Iron’s Mt Webber mine approximately 10km to the north-east.

Macarthur considers both tenements prospective for iron ore and is seeking interested parties to further explore these assets.

Overview of Strelley Gorge (E45/4735)

The Strelley Gorge tenement lies within the Lalla Rookh syncline composed of mainly Euro Basalt (A-KEe-b) metamorphosed basalt, komatiitic basalt and serpentinized peridotite. The tenement also contains two banded iron units prospective for DSO iron ore – the Paddy Market Formation on the eastern side and the Cleaverville formation on the west (see Figure 1 below). The latter hosts past iron ore mining operations of the Abydos project owned by Atlas Iron on the western edge of the tenement (see Figure 2 below).

Atlas Iron has also obtained EPA approval to commence the Sandtrax iron ore mine located in the BIF unit towards the north-eastern boundary (see Figure 2 below).

Reconnaissance rock sampling completed by Fe Limited (ASX:FEL) on the outcropping BIF along strike from the previously mined Atlas Abydos project returned high iron grades (61.3% and 58.11% Fe). The results, summarised in Table 1 below, were previously reported by FE Limited to the market in an ASX announcement dated 5 September 2019 (see announcement here).

Overview of Tambourah (E45/5324)

The Tambourah tenement lies within the Shaw Batholith comprised of the Callina Supersuite (A-CL-mg) – metadiorite to metasyenogranite; massive to gneissic rocks and the Tambina Supersuite (A-TA-mg) – metatonalite and metagranodiorite (see Figure 3 below).

The tenement also encompasses approximately 5.5km strike length of the Pincunah Banded Iron member. The Pincunah BIF hosts the iron ore deposits previously mined as part of Atlas Iron’s Mt Webber project 10km to the north east.

Historical reporting by Atlas Iron Ltd in 2012 (see Tables 2 and 3) highlighted the iron potential of the Pincunah Banded Iron formation within the tenement.   Their drilling of the MW08 Prospect (reported in an annual report to the Department of Mines and Petroleum prepared on behalf of Atlas Iron Ltd, and accessible on Wamex (Report Number A095162. Report titled: Mt Webber Project Annual Technical Report, dated 28 September 2012)) returned significant iron results over the 400 metres of strike that was tested with RC drilling. That drilling recorded significant intercepts in fourteen (14) of the twenty‐six (26) drillholes drilled on the MW08 prospect predominantly within goethite and goethitic haematite (see Figures 4 and 5).

Joe Phillips, Managing Director of Macarthur Minerals commented:

“It is beneficial to Macarthur shareholders for the Company to separate the Pilbara iron ore assets from the non-iron ore assets prior to the proposed ASX listing of Infinity Mining Limited, as currently Macarthur is being valued solely on the Lake Giles iron ore assets.  

“This transfer will allow all prospective tenements in the Pilbara to be appropriately resourced and drive value through exploration, back to shareholders. Macarthur will be looking to transact with a third party on the Strelley Gorge and Tambourah tenements so as not to distract resources away from the development of the Lake Giles hematite and magnetite projects.”

On behalf of the Board of Directors, Mr Cameron McCall, Chairman
