Positive Results from Financial Model for the Gravelotte Emerald Mine

URA Holdings Plc ("URA" or the "Company") is pleased to announce the results of an independent desk-based review of the Discounted Cashflow (DCF) model for the Gravelotte Emerald Mine (GEM) in South Africa, conducted by ACA Howe International Limited. This review is based on ACA Howe's extensive experience with the Gravelotte Emerald Mine, including their historical work, site visits, and Mineral Resource Estimation reported in accordance with the JORC code in the 2023 Competent Person's Report (CPR). The review highlights the potential profitability of the project over a 17-year mine life.

Highlights:

                •              Net Present Value (NPV) before tax at 10% Discount Rate of USD 22.39 million

                •              Internal Rate of Return (IRR) of 76%

Project turns profitable from year 2 of operations

·              Average Total Operating Cost per Tonne of USD 54.70 /t

Capital Expenditure (CapEx), excluding Sustaining CapEx: USD 2.58 million

                •              Operating Expenditure (OpEx): USD 67.28 million over Life of Mine (LOM)

                •              Life of Mine (LOM): 17 years

                •              Total Payable Ore: 1.23 million tonnes

                •              Average Annual Production: Ramping up to 90,000 tonnes per annum over 6 years

•             Estimated total Profit before Tax over LOM: $79.5 million

·              Payback Period: 2.5 years

Bernard Olivier, CEO of URA Holdings Plc, commented: "We are extremely encouraged by the results of the ACA Howe review, which confirms the potential robust economics of the Gravelotte Emerald Mine. The high IRR and positive NPV underscore the significant potential value this project can bring to our shareholders. With the initial production startup capital expenditure already completed, and the mine now back in production, we are well-positioned to advance this project and capitalize on the opportunities it presents. The model is based on our current Inferred JORC resource of 29m carats and an allowance for a small portion of the JORC Exploration Targets (up to 344 million carats) that are below the Inferred Resources to be upgraded and mined in years 14 to 17 of production, based on the significant exploration that is planned. Our experienced team is committed to executing our strategy and delivering long-term value. We also look forward to updating the market and our shareholders further on our ongoing operational activities shortly."

The ACA Howe review involved an assessment of the mining and processing estimates used in URA's DCF model. The review verified that the accuracy of the input data is reasonable given the level of planning completed to date and ensured that the proposed mining method and processing flowsheet are suitable for the deposit. Key factors such as mining costs, processing costs, and the overall economic assumptions were evaluated to ensure the reliability of the model. It is noted that more detailed planning would be required for the completion of a Scoping Study.

2. Geological Setting

2.1 Regional Geology

The GEM is situated in the Limpopo Belt, a geologically complex region characterized by high-grade metamorphic rocks and intrusive granitic bodies. The emeralds at GEM are primarily found in biotite schist, which is part of the Gravelotte Formation. This formation is intruded by granitic rocks of the Germania Hill Complex, which play a crucial role in the mineralization process.

2.2 Local Geology

The emerald-bearing zones are located in the Cobra and Discovery pits. These zones are associated with reaction zones between biotite schist and intrusive granitic bodies, and sometimes within fractures and micro-fractures within the schist.

3. Resource Estimates

The financial model is based on the current JORC Inferred Resource totalling 29m carats (year 1-14), plus approximately 8.5 million carats of JORC Exploration Target material from beneath the Inferred Resources (year 14-17) (Section 4). The economics are subject to change as more detailed work is completed and are based on Inferred Mineral Resources and Exploration Targets that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the results reported will be realized. More detailed planning would be required for the completion of a Scoping Study.

The Mineral Resources have been reported in accordance with the guidelines of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (2012 Edition)" ("JORC Code").

The Mineral Resource statement for Gravelotte is presented in Table 1 below. The estimate is in respect of in situ material.

Notes:

1.     Mineral Resources were estimated using the definitions and guidelines of the JORC Code.

2.     Assigned grades are derived from limited historical production and bulk sampling.

3.     Tonnages are derived from modelling of interpreted emerald-bearing schist based on historical drilling. A payability factor has been applied as acknowledgement that it has not been possible to model controls on mineralisation within the schist due to limited data.

4.     Both the estimates for Cobra and Discovery have been depleted by an approximate tonnage based on historical information and limited historical records.

5.     Inferred Mineral Resources have a large degree of uncertainty as to their existence and whether they can be mined economically. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

6.     The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral 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.

7.     A bulk density of 2.7 g/cm³ was used for the modelled emerald-bearing schist. The value used is based on the figure used by previous owners and assessment of lithologies intersected in drilling.

8.     The measure in Emerald Tonnes and Emerald Carats reflects the quantity after applying a 50% payability.

4. JORC Exploration Targets

The financial model assumes the conversion of approximately 8.5 million carats from the Cobra Pit and Discovery Main Exploration Targets, which are beneath the Inferred Mineral Resources described in Section 3. For the purposes of the financial model, URA has assumed that it will be possible to upgrade the Cobra Pit and Discovery Main Exploration Targets (years 14-17 in the DCF model), to Mineral Resources with additional exploration beneath the current Resource areas. However, it is not certain that this outcome will be achieved.

The remainder of the Cobra Pit and Discovery Main Exploration Targets, as well as the other Exploration Targets, as detailed in Table 2 below, are excluded from the financial model and represent further upside potential.

Exploration Targets are reported in accordance with Section 18 of the JORC Code and the following should be noted:

·      Exploration Targets must be expressed so that it cannot be misrepresented or misconstrued as an estimate of Mineral Resources or Ore Reserves;

·      any statement referring to potential quantity and grade of the target must be expressed in ranges

·      potential quantity and grade as reported in respect of the Exploration Targets are conceptual in nature;

·      for these additional areas, there has been insufficient exploration to define a Mineral Resource; and

·      it is uncertain if further exploration (as planned by the Company) will result in the determination of a Mineral Resource.

There is significant uncertainty implicit in the estimation of an Exploration Target as defined within the JORC Code. The JORC Code definition of an Exploration Target is as follows:

"An Exploration Target is a statement or estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tonnes and a range of grade (or quality), relates to mineralisation for which there has been insufficient exploration to estimate a Mineral Resource."

The JORC Exploration Targets (See Table 2 below) are all areas where the current database for the GEM property indicates that there is geological continuity with adjacent Mulati Formation ("MF") emerald-bearing schists. Modelling of potential emerald-bearing schist is based on the following:

·      Drilling and interpreted geological continuity beneath Inferred Mineral Resources - Cobra Pit, Discovery Main.

·      Historical mining and interpreted geological continuity beneath Cobra South pit - Cobra South.

·      Drilling and interpreted geological continuity along strike from Inferred Mineral Resources - Cobra Far North, Discovery West, Cobra South-Discovery West.

·    Other areas assessed by historical drilling but not along strike of Inferred Mineral Resources - Discovery South, Discovery North, Discovery Hill.

Notes:

1.     Exploration Targets are conceptual in nature and are not Mineral Resources.

2.     The tonnage, grade and content ranges as presented are meant to impart the conceptual nature of the Exploration Target in line with the JORC Code.

3.     Exploration Targets were estimated using the definitions and guidelines of the JORC Code.

4.     An Exploration Target is material that has a reasonable degree of geological confidence but for which there is insufficient exploration to define a Mineral Resource. It is not certain that further exploration will result in the target being delineated as a Mineral Resource.

5.     Assigned grades are derived from limited historical production and bulk sampling.

6.     Tonnages are derived from modelling of interpreted emerald-bearing schist based on historical drilling. A payability factor has been applied as acknowledgement that it has not been possible to model controls on mineralisation within the schist due to limited data.

5. Mining and Processing

5.1 Mining Method

Mining at GEM will be conducted using conventional open pit methods, including drilling, blasting, loading, and hauling with hydraulic excavators and articulated dump trucks. The mining schedule is designed to ramp up production from 30,000 tonnes per annum (tpa) in the first two years to a steady state of 90,000 tpa by year seven.

5.2 Processing Plant

The processing plant at GEM includes a jaw crusher, vibrating screens, trommel, and an Angelon CCD colour sorter. The plant is designed to maximize recovery while minimizing damage to the emeralds. The processing flow involves crushing, screening, and sorting, followed by secure storage of the emerald concentrate.

6. Sensitivity Analysis

The sensitivity analysis demonstrates that the project is most sensitive to changes in the selling price, grade, and recovery of emeralds. Variations in operating and capital costs have a less significant impact on the overall NPV.

6.1 Key Sensitivities

•             Selling Price: A 15% increase in selling price results in an NPV of USD 30.84 million, while a 15% decrease reduces the NPV to USD 13.94 million.

•             Output: A 15% increase in output results in an NPV of USD 27.91 million, while a 15% decrease reduces the NPV to USD 16.87 million.

•            Operating Costs: A 15% increase in operating costs reduces the NPV to USD 16.98 million, while a 15% decrease increases the NPV to USD 27.80 million.

7. Risks and Mitigation

7.1 Key Risks

•             Geological Uncertainty: The inferred resource estimates are based on historical data, which introduces uncertainty in the grade and distribution of emeralds.

•             Selling Price: URA has not commissioned an independent stone valuation and historical values have been used.

•             Security: Gemstone theft is a significant risk. URA has implemented extensive security measures to mitigate this risk.

•             Market Volatility: The price of emeralds can be volatile, impacting the project's financial performance.

7.2 Mitigation Strategies

•             Exploration: Continued exploration to upgrade Inferred Resources to Measured and Indicated categories. Additional exploration is planned to further assess the potential of the Exploration Targets.

•             Selling Price: An independent valuation will be completed when sufficient stones are available from the early stages of mining.

•             Security Measures: Implementation of advanced security protocols and continuous monitoring.

•             Market Analysis: Regular market analysis to adjust the selling price and optimize sales strategies.

8. Conclusion

The GEM project demonstrates strong financial potential with a significant NPV and IRR. The review by ACA Howe confirms the potential profitability of the project.

9. Cautionary Disclosures

·      The financial model is based on Inferred Mineral Resources (year 1-14) and Exploration Targets (year 14-17) that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorised as Mineral Reserves, and there is no certainty that the results reported will be realised. For the purposes of the financial model, URA has assumed that it will be possible to upgrade the Cobra Pit and Discovery Main Exploration Targets (years 14-17 in the DCF model), to Mineral Resources with additional exploration beneath the current Resource areas. However, it is not certain that this outcome will be achieved.

·      Note that Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability, and no Mineral Reserves have been reported for the Gravelotte Emerald Mine. Scoping, Pre-Feasibility and Feasibility studies have not been completed and the economic forecasts herein should be viewed as indicative, based on the information currently available. The economics are subject to change once more detailed studies are completed.

·      The JORC code states that caution should be exercised if Inferred Mineral Resources are used to support technical and economic studies.

·      Mineral Resources and Exploration Targets - see sections 3 and 4 above.

·      Mining - detailed mine planning has not been completed and ACA Howe has relied on CapEx and OpEx estimates based on quotes from suppliers and local knowledge, provided by URA. ACA Howe considers the mining method, proposed equipment, estimated CapEx and OpEx, and annual tonnages included in the DCF to be reasonable. CapEx and OpEx estimates are subject to change as more detailed planning is completed.

·      Processing - the encouraging testwork completed to date using the optical sorter has been in laboratory conditions only. ACA Howe has relied on CapEx and OpEx estimates based on quotes from suppliers and local knowledge. ACA Howe considers the proposed process flowsheet, associated CapEx and OpEx, and throughput included in the DCF to be reasonable. CapEx and OpEx estimates are subject to change as more detailed planning is completed.

·      Selling Price - URA has not commissioned an independent stone valuation and historical values have been used. ACA Howe are not gemstone market experts and have not verified the valuation applied in the financial model. The value per carat will be assessed by an independent expert when sufficient stones are available from the early stages of mining.
