About Deep Yellow Limited

Deep Yellow Limited is a differentiated, advanced uranium exploration company, in predevelopment phase, implementing a contrarian strategy to grow shareholder wealth. This strategy is founded upon growing the existing uranium resources across the Company’s uranium projects in Namibia and the pursuit of accretive, counter-cyclical acquisitions to build a global, geographically diverse asset portfolio. A PFS was completed in early 2021 on its Tumas Project in Namibia and a DFS commenced February 2021. The Company’s cornerstone suite of projects in Namibia is situated within a top-ranked African mining destination in a jurisdiction that has a long, well-regarded history of safely and effectively developing and regulating its considerable uranium mining industry.

Well Positioned for Growth

● Project portfolio is located in Namibia, a premier uranium mining jurisdiction with a long history of mining

• Dual-pillar growth strategy to establish a multi-platform, 5-10Mlb per annum, low-cost, tier one uranium producer

● Led by a standout uranium team

• A highly-credentialed and experienced team (majority ex-Paladin Energy) with proven success in the uranium sector, strong project development, operational and corporate capabilities

• Majority of this team successfully built and operated two innovative conventional uranium operations (Langer Heinrich, Namibia and Kayelekera, Malawi)

• Grew Paladin from a market capitalisation of A$2M to A$4Bn – pre-Fukushima

● Well-funded for future growth with cash balance of A$51M (+A$30M option conversion June 2022)

• Nuclear energy becoming the moral imperative, with positive momentum building globally

Advancing the Dual-Pillar Expansion Strategy

Key Ingredients Remain for Execution of Stated Growth Strategy

==> picture [252 x 378] intentionally omitted <==

Comprising both organic (Namibian project portfolio) and inorganic growth (targeted M&A)

Fundamental supply/demand disconnect remains unresponsive to the post 2023/24 predicted uranium shortage

Key major exiting the sector, other majors in a non-expansionary /contraction mode

Sector consolidation essential and should be completed during time of general low uranium pricing

Deep Yellow focussed on establishing a multi-platform, tier-one uranium operation, to provide security and certainty of uranium supply into a growing market

Excellent jurisdiction and infrastructure for development and mining

Responsible for ~6% of global uranium output

Namibia has a long history of uranium mining - currently the world’s 4th largest uranium producer producing 320Mlb since 1974

Large Province contains nearly 2Blb U3O8 Measured and Indicated and Inferred Resources with exceptional prospectivity

Large capacity, long-life mining operations established Rössing – 11Mlb/pa design

Husab – 15Mlb/pa design

Langer Heinrich – 5Mlb/pa design

Tumas Overview

Multiple deposits discovered along 55km of the 125km of regional channel explored to date

Tumas Project within 100% owned Reptile tenements Only 50% of the 125km highly prospective palaeochannel system has been tested

Exploration since early 2017 has increased the resources over threefold at an impressive discovery cost of 11.5cents/lb (A$)

Tumas Project is similar to deposit mined at the Heinrich which is well understood Langer very by the Deep Yellow team

Tumas Project Overview

13

==> picture [51 x 109] intentionally omitted <==

Tumas DFS Commenced following PFS

• Focused on an open-pit mining operation, with a production capacity of 3Mlb U3O8 per annum

• Highly positive PFS completed Jan’21 using only 50% of the total Mineral Resources with strong economic and growth characteristic on a 12-year LOM

Impressive 63% conversion rate from Indicated Mineral Resources to Probable Reserves

• Huge upside potential

Remaining 50% of Mineral Resources available for conversion for the DFS to achieve the stated goal of a +20-year LOM operation

50% of the tremendously prospective Tumas palaeochannel still remains to be tested

• Tumas DFS commenced Feb’21, advancing in line with forecasts of significant uranium price improvements expected from 2022, due to the looming uranium shortage likely late 2023/24 and beyond

Strong Pipeline of Newsflow

● 15,000m DFS resource upgrade drilling currently underway

• Drilling focussed on converting the remaining Mineral Resources to Ore Reserve status:

Commenced February: Drilling Tumas 3 East (3,000 to 3,500m) Mid-April: Drilling Tumas 3 West (4,500 to 6,000m)

May -June: Drilling Tumas 1 East (4,500 to 6,500m)

• Progressive upgrade of Mineral Resources to Indicated Resource category - reporting April to June with each MRE

• Commencement of detailed trade-off and optimisation studies - reporting throughout year

• Metallurgical optimisation test work utilising available 1,000kg of sample - reporting throughout year

• Nova JV drilling results on Barking Gecko - results expected in April

• Mining Lease application submission - June quarter 2021

A Differentiated Investment Thesis

● Deep Yellow has a differentiated approach for value creation built around a looming uranium shortage

• Substantial new production will be required with the sector is ill-prepared to deliver

• Lack of sufficient proven expertise and experience to build new mines due to severe impact of Chernobyl and Fukushima

• These factors will exacerbate the anticipated supply deficit

• Deep Yellow has formed its strategy to effectively dovetail into this emerging scenario

• Establish a project development pipeline via both organic and inorganic (sector consolidation) growth

• Develop as a globally diversified, multi-project Tier 1 uranium miner producing 5-10Mlb pa

• Utilise its in-house team having truly unique qualities as the only group that built 2 successful conventional uranium operations in the last 30 years coming from the mid-cap company sector

• Deep Yellow aims to become a reliable, multi-project supplier of uranium able to provide safe, long-term supply, production optionality and geographic diversity
