GoviEx Updates Madaouela Project Pre-feasibility Study Start-up Capital and Operating Costs Reduced

Vancouver, British Columbia--(Newsfile Corp. - February 18, 2021) - GoviEx Uranium Inc. (TSXV: GXU) (OTCQB: GVXXF) ("GoviEx or the Company") is pleased to announce the results of its updated pre-feasibility study ("Updated PFS") achieving key objectives set by the Company designed to advance the Madaouela Uranium Project (the "Project") towards Project financing and development.

Key Highlights:

  • Open pit mining in the early years with CapEx reduced by 15% and OpEx down by 20%
  • Captive water source, consumption reduced by 66%
  • Grid level electrical power existing within Project boundary
  • Prioritize local skilled labour and local venders
  • Straightforward industry standard process design - reducing construction and operational risks
  • Mining Permit and Environmental Certificate already secured
  • Potential to service debt of USD 150-180 million
  • Ability to fast track feasibility study in 2021 to target rapid development
  • Next steps to accelerate project financing and offtake options

The Updated PFS succeeded in delivering a project that is technically robust and significantly simplified, reducing development and operational risk. The mining operations at the Project are planned to commence by open pit at the Miriam deposit in order to improve cash flows in the early years of the Project, while achieving this at a much lower uranium price with potential for attractive debt financing. The Updated PFS on the Project now accounts for five years of inflation and currently quoted costings since the previous pre-feasibility study issued in 2015(1) (the "2015 PFS").

"We are delighted with the series of elegant engineering solutions our technical team has achieved under the leadership of our CEO, Daniel Major, to place the Madaouela Project in pole position and to potentially bring Madaouela online as one of the first new mines developed in this exciting new uranium cycle" said Govind Friedland, GoviEx's Executive Chairman.

"The Updated PFS further indicates the technical strength of GoviEx's main uranium project in Africa" commented Daniel Major, GoviEx's Chief Executive Officer. "Lower costs, lower technical risk and financing potential are the main results from this study. The current structural deficit in the uranium market requires that new mines are developed in the near term to continue the generation of carbon-free nuclear power. GoviEx has taken another important step towards further developing our mining plans through completing this Updated PFS."

Mineral Reserves for the Project have been defined based on a forecast price of USD 55 per pound of U3O8.

GoviEx's internal technical team, working closely with consultants SRK Consulting (UK) Limited and SGS Bateman (Pty) Ltd., has succeeded in simplifying the process plant design, reducing the technical risks of commercially untested options considered in the 2015 PFS, while at the same time increasing uranium recovery and reducing unit operating costs. Uranium recovery is reported as 94.5% for the open pit ore and 92.5% for the underground ore, while molybdenum recovery is improved from 67.0% to 84.7%, and processing life of mine costs have been reduced by 8% or USD 2 per pound of U3O8.

The mining rate for the Miriam open pit deposit has been rescheduled to ensure the tenor covers any potential debt financing for the Project development.

Operating Cash Costs, excluding royalties and including molybdenum by-product credits, over the first four years of the mine life are reduced by 20% or USD 4.7 per pound to USD 18.3 per pound of U3O8, and capital costs have been reduced by 8% or USD 29 million.

Under the Updated PFS, the open pit alone has the potential to service debt of USD 150-180 million at a U3O8 price of USD 50-55 per pound, as modelled by the Company's debt advisors.

The results of the Updated PFS will be reported in a technical report in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects, which will be available on the Company's website (www.goviex.com) and under the Company's profile on SEDAR (www.sedar.com) within the next 45 days.

Updated PFS Overview

The Project is situated in the Agadez region in the northern part of the Republic of Niger adjacent to the existing Orano SA operations of Somair and Cominak, and benefits from the existing infrastructure and an experienced uranium mining labour force. GoviEx operates the Project and holds an 80% interest with the remaining 20% held by the Republic of Niger, of which 10% represents a free-carry. The Project also includes a series of other deposits that are anticipated to be mined by either open pit or underground methods.

Calculations for the Mineral Reserves for the Project, reported in accordance with the CIM standards and guidelines, under the Updated PFS were based on a USD 55 per pound U3O8 price. Total Probable Mineral reserves are reported as 24.9 million run-of-mine ore tonnes with an average ore grade of 0.85 kg/tU, the contained uranium of 21,054 tU (54.7 Mlb U3O8).

Open Pit Mining

Mining operations for the Project are planned to be based initially on standard truck and shovel open pit mining for the Miriam deposit at a planned rate of 1 Mt per annum of ore feed to the process plant, which results in an initial six years of mining operations at Miriam. This production rate ensures that the life of the Miriam deposit would exceed the expected potential debt tenor.

The life of pit stripping ratio was reduced to 9.9:1 from the 12:1 set out in the 2015 PFS, partly due to steeper final pit walls at 53 degrees versus 51 degrees previously used in the 2015 PFS. Post capital pre-strip stripping ratio was reduced from 8:1 to 7:1. Mining operating and capital costs have been updated with a high degree of confidence as they are based on current supplier quotes to define owner operator operating costs of USD 2.3/tonne mined.

Underground Mining

The M&M and MNSE-Maryvonne deposits are planned to be mined by room and pillar, similar to the adjacent Orano S.A.'s Cominak mine. Ore mining is designed to be undertaken at a rate of approximately 1.4 Mt per annum. Mined ore is to be fed onto a conveyor via feed breakers at each panel. Run of mine ore is then planned to be sorted by X-ray fluorescence ("XRF") to remove waste dilution. Post XRF sorted ore is designed to be trucked to the process plant at a rate of 1.0 Mtpa. Underground mining operations are forecast to mine at an average of USD 31.71 /ROM tonne.

Mineral Processing

Process plant and associated mine infrastructure has been moved from its previously planned site next to the proposed M&M underground works to adjacent the Miriam open pit in order to reduce the additional ore hauling costs in the early years.

Due to the insufficient commercial operations of Ablation and Solvent Extraction ("SX") as process routes, which are contemplated in the 2015 PFS, the Company undertook a considerable program of processing test-work with an aim to reduce the technical risks associated with the application of these two process routes, targeting ore upgrading, acid consumption reduction and general reduction of costs. The test-work completed included: de-sliming, Energy X-ray Transmission "(XRT") sensor sorting, gravity, nano-filtration, Ion Exchange ("IX") and flotation.

In addition, work focused on the differing mineralogy of the Miriam deposit geology in comparison to that of the M&M deposit, from which historical bulk samples were used to define metallurgical test work. Substantially lower calcite and dolomite composition of the Miriam ore relative to M&M ore results in a markedly lower forecast acid consumption.

Consequently, a pragmatic approach was adopted to utilize a simple and proven flowsheet including whole ore leaching to treat the ore arising from the open-cast Miriam operation, which has relatively low gangue-acid consumers ("GAC"), and then add XRF based ore sorting and reverse flotation in later years, when the underground ore with higher acid consumption is treated. The resulting simplified flowsheet adheres to the following steps:

During the early years when low GAC ore from the Miriam deposit is to be treated:

  • Secondary crushing and milling
  • Two-stage tank acid leaching of the whole ore to produce a pregnant leach solution containing uranium molybdenum, iron and other impurities
  • Belt filtration for leach residue dewatering, followed by tailings disposal by dry stacking
  • Recovery of molybdenum by IX using Purolite S970 resin
  • Recovery of uranium by SX using Alamine 336
  • Precipitation of uranium using ammonia

The resultant process plant design simultaneously reduces acid and water consumption while also improving the uranium and molybdenum recovery.

Key Process Design Parameters

Parameters
Annual ore feed to process plant 1,000,000 tpa
Uranium recovery 94.5% O/P, 92.5% U/G
Molybdenum recovery 84.7%
Acid Consumption per tonne ore feed 30.5 kg/t
Raw Water Feed 102 m3/hr

 

As a result of the revision in ore reserves and resulting associated mining and operations, the life of mine operations for the Project is forecast to last 20 years, producing an estimated total uranium sales of 49.65 Mlbs U3O8, averaging 2.48 Mlb U3O8 per annum life of mine.

The simplification of the process flowsheet and the extensive level of test work already completed by the Company readily translates to a feasibility study that should require very limited confirmatory test work, and any test work that will be required, will likely focus on optimization of the leaching and ion exchange recovery processes.

The Updated PFS includes a high-level of detail on all aspects of other costs of the Project. This includes detailed quotations covering security operations, on-site administration costs and, importantly, sales and transport costs to North America and Europe of finished product. The table below summarizes unit operating costs of production for the initial four years of operation and life of mine. The Company reports that for the first four years of operation, the cash operating costs, excluding royalties and including credits for molybdenum, have been reduced by approximately 20% or USD 4.5 per pound of U3O8 sales to USD 18.3 per pound of U3O8 sales, and life of mine are reduced 8% to USD 22.2 per pound of U3O8.

A contingency of 10% is included in the capital figure quoted above.

The benefits of capital cost optimisation and the delay in the development in underground mines results in a projected USD 66 million reduction in capital over the first five years and contemplates that the Project has an undiscounted payback by year 5 of commercial production.

Based on a uranium price of USD 55/lb U3O8 over the life of mine, the Project is forecast to produce a USD 525 million in free cash flow, including capital expenditure, and is forecast to produce an annual average of USD 70 million EBITDA.

The Updated PFS focused on improving the Project with a number of key targets that the Company was seeking to achieve and, on balance, these targets have been achieved and include:

- Ensure the Miriam open mining pit covers any potential debt tenor
- Simplify and reduced the technical risk associated the process design
- Reduce the operating and capital costs of the project from that set out in the 2015 PFS
- Improve the level of detail of the project, and ensure contingency coverage
- Simplify the requirement for completion of a feasibility study

In addition, the strength of the Project is highlighted by its potential to service USD 150-180 million of debt finance based on a uranium price of USD 50-55/lb U3O8 and using conservative debt covenants.
