• Supply - Expected to fall 3.5% pa to 2030 due to depleted mines

• Demand - Significant production increase required by 2040

• New mines are essential to meet demand

• South 32 (17-1-22) - 1.5° (Climate Change Scenario): https://www.south32.net/docs/default-source/exchange-releases/hermosa-project-update-presentation43ee85d99c0a4238ab2df792d986f3d3.pdf?sfvrsn=24bde72d_4 • 6 x increase in renewable energy capacity to 2050, with wind increasing by 10x and solar by 14x

• Primary Zinc Demand increasing 2x to 24mt

• Initial Exploration Target: Open pit proposition 100-120Mt (3.5% - 4.5% Zn-Pb Sulphide)*

• -

• Globally only 8% of zinc is mined open pit significantly lower mining costs

• Few deposits that have comparable scale – Globally significant discovery

• 92% of zinc is mined underground – Substantially higher mining costs

• High potential to discover new structurally hosted high-grade underground deposits

• Recent Zn-Pb asset transaction :

• South 32 purchased Hermosa Deposit Arizona ( underground Zn-Pb mine ) for US$1.3bn (A$2.0bn)*

*The potential quantity and grade of the exploration target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The exploration target is based on the current geological understanding of the mineralisation geometry, continuity of mineralisation and regional geology. This understanding is provided by an extensive drill hole database, regional mapping, coupled with understanding of the host stratigraphic sequence.

Earaheedy Project Initial Exploration Target	Earaheedy Project Initial Exploration Target	Earaheedy Project Initial Exploration Target
Range	Tonnes	Grade
Lower	100,000,000	3.5% Zn + Pb Sulphide
Upper	120,000,000	4.5% Zn + Pb Sulphide

Notes:

Rumble’s initial first stage exploration target at the Earaheedy Project is between 100 to 120 million tonnes at a grade ranging between 3.5% Zn-Pb to 4.5% Zn-Pb Sulphide. The exploration target is at a shallow depth (120m), and over 40kms of prospective strike (completely open) has been defined within the Earaheedy Project. The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The exploration target, being conceptual in nature, takes no account of geological complexity, possible mining method or metallurgical recovery factors. The exploration target has been estimated in order to provide an assessment of the potential for large-scale Zn-Pb deposits within the Earaheedy Project. The exploration target has been prepared and reported in accordance with the 2012 edition of the JORC Code.

Included in the data on which this exploration target has been prepared are results from over 50,000m of drilling completed by Rumble. Historic drilling includes sixty-four (64) holes completed within the project area (E69/3464) by previous explorers (refer historical exploration results in previous ASX announcements dated 5 February 2019 and 12 October 2017, 23rd January 2020 which continue to apply and have not materially changed).

The Company intends to test the exploration target with drilling and this further drilling is expected to extend over approximately 12 months. Grade ranges have been either estimated or assigned from lower and upper grades of mineralisation received in drilling results. A classification is not applicable for an exploration target

Some of the considerations in respect of the estimation of the exploration target include:

The potential quantity and grade of the exploration target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The exploration target is based on the current geological understanding of the mineralisation geometry, continuity of mineralisation and regional geology. This understanding is provided by an extensive drill hole database, regional mapping, coupled with understanding of the host stratigraphic sequence.

• Drilling results have demonstrated strong continuity of shallow, flat lying mineralisation;

• o Over 42km’s of prospective strike and open

• Minimum 600m width (based on shallow 7.5 ° and shallow depth to 120m, based on drilling results.

• True width (thickness) of mineralisation up to 51 metres received in drilling results; and

• Specific gravity (SG) of 2.5 (world average SG of sandstone – not accounting for metal).

Overview

• Zinc is one of the most versatile and essential materials known to mankind. It is the fourth most used metal in the world behind iron, aluminum, and copper.

• The primary use of zinc is in the galvanizing process, which protects iron and steel from rusting. Zinc coatings play a key role in public transportation and infrastructure by extending the life of steel used in bridge rails and support beams, railway tracks, and public transportation hubs and terminals.

• Additionally, zinc can be alloyed with other metals and used for diecasting into shapes such as door handles, alloyed with copper to make brass, and alloyed with copper and sometimes other metals to make some types of bronze, like architectural bronze or commercial bronze.

• Furthermore, zinc also has applications in energy storage. Zinccarbon batteries were the first commercial dry batteries, providing a higher energy density at a lower cost than previously available cells.

• Due to its growing role in energy storage and its superior ability to protect metals against corrosion, zinc remains an essential material for the future.

Zinc is 100% recyclable – it can be recovered and reused without a loss in quality

Offshore wind turbines require a zinc coating to Zinc handle extreme coatings environmental conditions protect solar panel fixtures and A 10 MWh prevent rust offshore wind turbine A 100 megawatt hour required 4 (MWh) solar power park tonnes of requires 240 tonnes of zinc zinc

• 1 • Zinc is a key ingredient in battery technology that enables carbon emission reduction

2 • Zinc-ion batteries are safer than lithium-ion batteries as they use water-based chemistry (avoiding fires)

3 • Galvanised steel requires zinc and is the preferred material used by EV manufacturers
