2021 Calendar Year Goals

Macarthur is well placed to deliver on its stated 2021 goals. These include:

• Feasibility Study for Lake Giles Iron Project: Completion of the Feasibility Study for the Lake Giles Iron Project (including a route to market operating model that will support export through Esperance Port and securing a strategic partner for project development) is a core goal. The Feasibility Study is highly technical and resource intensive, requiring attention to infrastructure design, project approvals, logistics planning, mine planning, metallurgical test work, process flow for magnetite beneficiation and detailed financial modelling. The internal focus on progressing the Feasibility Study forward during this period has been substantial, and the Company has made a series of announcements about strategic appointments and activities that are critical in ensuring its delivery in the shortest possible timeframe. The Company will continue to release regular updates on the Feasibility Study to ensure the market is kept fully informed on the study's progress.
  
  
• Repositioning of Non-Iron Ore Pilbara Assets: On 24 February 2021, Macarthur announced a repositioning the Company's 100% owned, 720km? gold, copper, zinc, manganese and lithium exploration tenements in the Pilbara region of Western Australia under a three-way deal with Zanil Pty Ltd and Timeless Capital Corp. Following the announcement of that transaction, the Company completed the technical and valuation work on Macarthur's Pilbara tenements and on a package of gold tenements in the Leonora region of Western Australia (which are currently under option by the Company with Zanil Pty Ltd). An independent valuation of those assets placed a materially higher value on Macarthur's Pilbara tenements than was reflected in that deal and the Company announced a termination of the Letter of Intent in early April 2021. As a consequence of the original transaction not proceeding, the Company is currently examining options to unlock the value of the Company's Pilbara assets via a separate listing on the ASX. The Company anticipates that a spin-out of the Pilbara tenements through an ASX listing has the potential to deliver a superior outcome for Macarthur and its shareholders.
  
  
• Early Hematite Production: The Company is seeking to advance an early production opportunity for the hematite resource at Lake Giles in light of current strong demand and pricing for iron ore. An early export opportunity for the hematite can only be advanced when an export solution can be contracted, and the Company is actively working towards developing the lowest cost, end to end transport logistics solution that will sustain operations. To achieve an accelerated export opportunity, the Company will leverage previous studies undertaken on the Ularring hematite resource that outlined an opportunity for direct shipping iron ore. The Company intends to make an announcement on further progress with this strategy soon.
  

In addition, the Company will also focus on a series of complementary goals. These will include:

• Strategic Partnerships: Formalising strategic partnerships for the key development and infrastructure requirements needed to commercialise the Lake Giles Iron Project.
  
  
• Project Financing: Advancing terms for financing of the development of the Company's high grade magnetite resources at Lake Giles to ensure a smooth pathway to the prompt closing of finance post-delivery of a successful Feasibility Study.
  
  
• Nevada Lithium Assets: Formalising a strategic partnership that can advance a programme of works to realise an improved value proposition for the Company's 100% owned lithium brine claims in the Nevada region of the USA. Macarthur holds 210 lithium brine mining claims in Nevada, covering an area of 7 square miles (18 km²) located in Railroad Valley, in Nye County, Nevada, USA. The claims are located approximately 180 miles (300 km) North of Las Vegas, Nevada, and 330 miles (531 km) South East of Tesla's new Gigafactory.
  
  
• Graduation on to main board of TSX: The company intends to progress its plans to migrate from the TSX-V onto the main board of the TSX during the course of the year.
  

All of these stated goals have the potential to unlock unrealised value in the Company for the benefit of shareholders.

Iron Ore Market Overview

Current iron ore demand is all about China, and recent UBS economics forecast has China's GDP growth rate at 8.2% in 2021. UBS economics comments also pointed to this GDP growth being driven by domestic and export-focused production, with exports of finished products estimated to grow at 11-12% over the 2021 year.

Further, the steel industry is observing the collision of market growth and de-carbonisation for steel producers. If global CO₂ emissions targets are to be met by 2050, then new capital investment in steel production must consider cleaner processes and ultimately transition away from traditional Blast Furnace process utilising coal as the reductant, towards scrap steel and DRI feed with hydrogen as the reductant.

On the commodity supply side, iron ore producer's capacity investment decisions are tempered with the memory of, and looks back to, the "hot 2008" market. At that time, high prices drove substantial capacity investment, only to be met with a sustained market demand slowdown where iron prices reached a low of USD38/Mt. Unlike the pricing for +62% Fe seen in 2008 and during the first 9 months of 2011, current prices do not appear to be tempered by the higher freight rates for cape size vessels that were seen during the 2008 - 2009 period.

Iron Ore Pricing Overview

Iron ore pricing is variable and traditionally the Chinese New Year holidays coincide with annual steel mill shutdown and lower demand for iron ore, but a December 2020 Platts Iron history is now reporting the iron ore pricing has been sustained in Q1, 2021. In fact, Traded Economics (13 April 2021) reported that iron ore benchmark 62%Fe increased USD15.20/Mt or 9.75% since the beginning of 2021. The World Steel Association, forecast annual steel output to grow 4.1% in 2021. This growth is being driven by three factors:

1. Pent up COVID-19 demand;
2. Increased Chinese steel production; and
3. Steel infrastructure inputs into National Governments' stimulus programs.
   

As at 19 April 2021, the +62%Fe spot price (CFR level) was US$177.70/dmt and +65%Fe spot price (CFR level) was US$211.50/dmt (source: custeel.com). Global iron ore prices have remained strong over the course of Q1 2021 with +62%Fe regularly trading above USD172/dmt (CFR level) and the premium for +65%Fe remaining consistently high. Prices for +62%Fe have certainly been relatively stable, above USD150/dmt (CFR level) throughout the last 12 months, and although Chinese steel outputs have recently come off, some analysts have noted that there has been a surge for high grade spot supply as steel margins surge. This may be buying some time before displacement of marginal supply kicks in, amplified by decarbonisation, as steel output trends lower and supply gets seasonally stronger.

The drive towards low carbon steelmaking is expected to increase demand for pellet feed, building a strong case for China to build direct reduced iron (DRI) hubs over the coming years, based on high grade, low impurity iron ore pellets. That's a perfect scenario for the development of the story for Macarthur's high grade magnetite concentrate.

Share Price

Both ASX and TSXV continue to demonstrate reasonably synchronised share price trading patterns for MIO and MMS. Although Macarthur's share price has pulled back over the course of February and March, off the high that was reached after the announcement of the MOU with Southern Ports Authority, this may largely be reflective of market expectations regarding announced progress on both the Feasibility Study and anticipation of an announcement of a pathway to early DSO production. Shareholders can be assured that both objectives continue to be the subject of the highest focus by Management during 2021.

A summary of MIO/MMS trading activity for March 2021 is shown below:

Andrew Bruton, Chief Executive Officer of Macarthur Minerals commented:

"The Company has been implementing an exciting agenda of value-driving objectives for the 2021 calendar year. I was surprised the market for MMS and MIO equities has retreated off the high generated by the announcement of the Port MOU.

Progress on the Lake Giles Iron Project is tracking well. As I committed in the last Quarterly Update, the focus on completing the Feasibility Study for our magnetite operations is paramount, and regular updates have been provided to the market in this area. The Company continues to materially progress commercial negotiations for infrastructure location and port access, allowing the Company to focus on finalising the necessary metallurgical test work and process flow for magnetite beneficiation, together with the engineering design works for the magnetite process plant and the non-process infrastructure required for the development of the mine.

In addition, the Company's Managing Director, Mr. Joe Phillips, has been focused on repositioning the Company's non-iron ore Pilbara and Nevada asset portfolios, ensuring that the Company can maximise the value of these assets for the benefit of shareholders. Our shareholders will recall that during the last reporting period a transaction involving the Pilbara assets was announced, but an independent valuation placed a materially higher value on these assets than was reflected in that deal. As a consequence of the original transaction not proceeding, the Company is currently examining options to unlock the value of the Company's Pilbara assets via a separate listing on the ASX. The Company anticipates that a spin-out of the Pilbara tenements through an ASX listing has the potential to deliver a superior outcome for Macarthur and its shareholders.

Macarthur has a very active year planned and I will keep shareholders across key developments, including regular updates on the continued progress of our Feasibility Study for Lake Giles and planned early hematite mining intentions."

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