Appia Re-Evaluates Potential of Its Elliot Lake Uranium Deposits in View of Increased Uranium Prices, Confirmation of Significant Rare Earth Mineralization and Bulk Mining Potential

Toronto, Ontario--(Newsfile Corp. - November 16, 2023) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0.F) (FSE: A0I0.MU) (FSE: A0I0.BE) (the "Company" or "Appia") is pleased to announce that the Company is revisiting its large uranium-rare earths deposits located at Elliot Lake, Ontario to examine the impact of increased uranium prices and confirmation of significant rare element ("REE") mineralization. The Company will also evaluate the cost-saving potential of bulk mining the Teasdale Lake and Banana Lake Zones.

In 2007-08 and 2012, Appia completed drill programs to confirm mineralization detailed in historical resource estimates for the Teasdale Lake and Banana Lake Zones. Following the drill program, Appia engaged consulting firm Watts, Griffis and McOuat Limited (WGM) to provide an updated NI 43-101 Resource Estimate for the two zones.

The technical report was prepared in accordance with the provisions of National Instrument 43-101 and entitled "UPDATE REPORT ON THE APPIA ENERGY CORP. URANIUM-RARE EARTH PROPERTY, ELLIOT LAKE DISTRICT, NORTH-CENTRAL ONTARIO, CANADA" by Watts, Griffis and McOuat, dated July 30, 2013 (the "2013 Updated Resource Estimate Report") and filed on SEDARplus at www.sedarplus.com on August 14, 2013.

The NI 43-101 Indicated Mineral Resource for the Teasdale Lake Zone was 14,435,000 tons grading 0.554 lbs U₃O₈/ton and 3.30 lbs. TREE/ton for a total of 7,995,000 lbs. U₃O₈ and 47,689,000 lbs. TREE. The Inferred Mineral Resource was 42,447,000 tons grading 0.474 lbs. U₃O₈/ton and 3.14 lbs. TREE/ton totalling 20,115,000 lbs. U₃O₈ and 133,175,000 lbs. TREE — see Table 1.

The Inferred Mineral Resource for the Banana Lake Zone was 30,315,000 tons grading 0.912 lbs. U₃O₈/ton for a total of 27,638,000 lbs. U₃O₈ — see Table 2.

The historical resource for the five separate zones comprising Appia's Elliot Lake Property is summarized in Table 3.

Summary of Teasdale Lake Zone Uranium and Rare Earth Mineral Resource Estimate

Notes

1.Mineral Resources effective 30 July 2013 1. Mineral Resources are estimated at a cut-off value of $100 per tonne, using a uranium price of US$70/lb U3O8, a TREE price of $78/kg, and a C$:US$ exchange rate of 1:0.9.
2. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
3. The quantity and grade of reported Inferred Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.

Notes

1.The historical resource was not estimated in accordance with definitions and practices established for the estimation of Mineral Resources and Mineral Reserves by the Canadian Institute of Mining and Metallurgy ("CIM"), is not compliant with Canada's security rule National Instrument 43-101 ("NI 43-101"), and unreliable for investment decisions.
2.Neither Appia nor its Qualified Persons have done sufficient work to classify the historical resource as a current mineral resource under current mineral resource terminology and are not treating the historical resources as current mineral resources

Increasing Uranium Prices and Strong Rare Earth Interest

The Spot Market price for uranium has moved significantly higher in 2023 YTD and is up threefold from its bear market bottom in 2019. Favourable supply and demand fundaments are expected to strongly influence uranium prices going forward. REEs have also attracted strong interest due to supply chain issues and concerns about China's dominance of REEs processing.

"Appia's uranium portfolio of both past producing and earlier-stage projects positions the Company well to participate in the long-term uranium market appreciation," stated Tom Drivas, CEO. "The Company holds a large ground position in Elliot Lake with a historical resource (non-compliant) totalling approximately 199 million lbs. of uranium at a grade of 0.76 lbs. U3O8/ton. Additionally, the Company holds four high potential early-stage uranium projects in the prolific Athabasca Basin — Loranger, North Wollaston, Eastside and Otherside."

"Many analysts are predicting higher uranium prices going forward due to a uranium deficit," stated Stephen Burega, Appia's President, "and the uranium market is currently in a production deficit that is expected to significantly increase with the build-out of nuclear reactors as the global demand for reliable clean base load energy increases. The increased interest in uranium and REEs, plus the cost-savings potential of bulk mining bode well for Appia's Elliot Lake Project."

Drilling Programs Confirm REEs and Outlines Larger Resource in Teasdale Lake Deposit

The 2007-08 and 2012 drill programs were also carried out to determine the REEs content in the various mineralized beds that comprised the Teasdale Lake deposit. Based on historical yttrium production and the presence of monazite, which is commonly enriched with REEs, it was recognized by Appia that the Elliot Lake uranium deposits could contain significant REE mineralization.

The drilling programs totalled 10,780 metres and indicated that additional drilling would continue to enlarge the zones.

The drilling confirmed the presence of three mineralized units, namely the Upper Reef, Intermediate Quartzite, and the Lower Reef:

• The 3.2 metre-thick Lower Reef horizon, which was mined extensively when the Elliot Lake camp IN was in production, contained significant REE mineralization and the highest uranium values.
• The Intermediate Quartzite averaged 2.65m in thickness and was weakly mineralized with lower uranium and REE mineralization.
• The Upper Reef, measuring 3.95m in thickness, contained the highest concentration of REE mineralization but lower uranium values compared to the Lower Reef.

The 2013, "Updated Resource Estimate Report for the Teasdale Zone", incorporated the significant REE mineralization in the Upper Reef and Intermediate Quartzite units as well as the higher-grade Lower Reef. The minimum vertical thickness was increased to 5.0m to accommodate the use of larger underground equipment as a cost-reduction strategy. The inclusion of all three mineralized units as well as the expansion of the minimum vertical thickness increased the resource tonnage for the Teasdale Zone to 14,435,000 Indicated tons plus 42,447,000 Inferred tons of uranium and REE mineralization versus 17,458,200 tons of uranium mineralization in the historical resource estimate. The total rare earth metal content was increased by approximately 6 times the uranium content.

The individual REEs included in the TREE Mineral Resource for the zone are listed in Table 4.

Optimizing Mining Based on Grade Distribution, Metal Prices and Mechanization

The significant rare earth mineralization in the Upper Reef provides several possible mining scenarios. The uranium-rich Lower Reef could be mined selectively to optimize revenue during periods of high uranium prices but lower REEs prices. Alternatively, the REEs enriched Upper Reef could be mined, followed by the removal of the Intermediate Quartzite to be used as backfill, and then mining the Lower Reef containing higher-grade uranium. A third alternative is to mine all three units simultaneously using larger mining equipment to increase production rates and lower mining costs. It is Appia's intention to evaluate all three mining scenarios under varying metal prices for uranium and REEs.
