Giyani Announces K.Hill Project PEA with Base Case Post-Tax NPV(8%) of US$983 million for a 57-Year Project Life and Upside Case NPV(8%) of US$1.6 billion

TORONTO, July 31, 2023 (GLOBE NEWSWIRE) -- Giyani Metals Corp. (TSXV:EMM, GR:A2DUU8) ("Giyani" or the "Company"), developer of the K.Hill battery-grade manganese project in Botswana (“K.Hill” or the “Project”), is pleased to announce a new Preliminary Economic Assessment (“PEA”) for K.Hill following the release of the significantly increased Mineral Resource Estimate (“MRE”), announced on July 13, 2023.

The PEA has a base case scenario (“Base Case”) considering a single production line to process K.Hill manganese oxide (“MnO”) material on-site to produce high-purity manganese sulphate monohydrate (“HPMSM”), with feed capacity of 200,000 tonnes per annum (“tpa”) over a 57-year life-of-project (“LOP”). An upside case scenario (“Upside Case”) is also evaluated, assuming an additional production line from Year 5 of operations taking total feed capacity to 400,000 tpa.

The PEA was prepared by CSA Global South Africa, an ERM Group company (“CSA Global”) in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101").


  • Base Case post-tax net present value using an 8% discount rate (“NPV8%”) of US$983 million (C$1.3 billion) and post-tax internal rate of return (“IRR”) of 29.4%.
  • Updated MRE allows for high-grade mine scheduling and an average plant feed grade of 19.1% MnO in the first 5 years of production, with an average grade of 17.3% for the first 25 years of production.
  • Base Case LOP is 57 years with total production of 3.6 million tonnes (“Mt”) of HPMSM.
  • Upside Case post-tax NPV8% of US$1.6 billion (C$2.1 billion) and post-tax IRR of 33.5% over a 25-year LOP.
  • Total initial capital expenditure of US$284 million, with an additional US$208 million of expansion capital required in Year 4 of the Upside Case.

Danny Keating, President and CEO of the Company, commented:

“The recently updated MRE and PEA redefine K.Hill as an exceptionally high value, long-life project capable of supplying high quality, low carbon HPMSM to lithium-ion battery customers for more than 50 years.

With the operating parameters of the process plant already defined, the PEA demonstrates the economic value of the larger project life offered by the updated MRE and potential upside scale of operations. These are material improvements and provide the solid basis to commence a new and optimized feasibility study (“Optimized Feasibility Study”) to be completed in 2024, capturing all the learnings and results from the demonstration plant (“Demo Plant”) and the results and feedback from off-taker analysis of the HPMSM production. We believe K.Hill has the capacity to move materially down the cost curve as we refine our operating and procurement strategy, including possible over-the-fence production of key reagents by third parties.

In parallel with our activities on the PEA, we remain focused on our core objectives. The construction of the Demo Plant continues in Johannesburg, and we remain in regular contact with the Botswana Department of Environmental Affairs (“DEA”) for approval of our Environmental Impact Statement (“EIS”) submission, which is required for the Mining Licence application.

The PEA is an important step forward to demonstrate K.Hill’s strategic importance to off-takers. It prepares a solid platform for commencing our Optimized Feasibility Study and reflects the Company’s value potential to our shareholders and investors.”

Notes: See Project Summary

An Upside Case for K. Hill has also been considered, with an additional production line from Year 5 of operations taking total feed capacity to 400,000 tpa. The Upside Case requires US$208 million of additional capital for the expansion, part of which can be supported from Project free cash flow.

The result is an Upside Case post-tax NPV8% of US$1.6 billion (C$2.1 billion) and post-tax IRR of 33.5%.

The Base and Upside Cases reflect the optionality available to the Company to meet the long-term supply needs of lithium-ion battery off-takers as well as the ability to expand and maintain or grow market share as demand for HPMSM increases. With more stringent regulations in North America and Europe regarding sourcing of EV battery metals, Giyani’s aim is to be the leading global supplier of non-China sourced HPMSM.

Project Summary

K.Hill, which is 100% owned by Giyani’s wholly owned Botswana subsidiary Menzi Battery Metals (Pty) Limited (“Menzi”), has been assessed as an integrated mining and processing operation for the on-site production of HPMSM directly from manganese oxide material mined at K.Hill.

On July 13, 2023, the Company announced an updated MRE issued by CSA Global for the Project. The MRE reflected a 310% increase in Indicated Mineral Resources and a 97% increase in Inferred Mineral Resources. This significant increase offers the Company greater flexibility in its mine planning and grade scheduling to optimise the feed grade to the plant, as well as extending the operating life of the Project.

The K.Hill orebody will be extracted from an open-pit using conventional truck-and-shovel mining methods and the PEA assumes a contractor mining execution strategy. In order to optimise the feed to the plant, material mined will managed through dedicated high/medium/low grade stockpiles, ensuring security of supply to the plant at the highest available grade.

The mining schedule in the PEA has focused on early extraction of high-grade material. The increased resources defined in the MRE offers greater operational flexibility for maintaining higher grade feed to the plant to generate strong early cashflows, while delivering a LOP that is significant for off-takers and customers.

The Base Case assumes a processing plant designed with a throughput capacity of 200,000 tpa and a two-year ramp-up schedule to meet the target recovery, reflecting the sophisticated nature of the K.Hill processing plant. The plant will produce HPMSM from K.Hill manganese oxide material using a hydrometallurgical process which does not require any carbon-intensive calcination or electrowinning. Under the Upside Case, a second 200,000 tpa production line will be constructed in Year 4 of the K.Hill operation and commissioned in Year 5.

CPM Group LLC (“CPM”), an independent research and consultancy company based in New York and specialist in analysis of the high-purity manganese market, was engaged in 2022 to complete a HPMSM products market outlook study. The PEA has used CPM’s forecast HPMSM prices, realized at the Project’s gate and net of transportation costs and applicable tariffs, with 50% of sales to the EU (Berlin) and 50% of sales to North America (Detroit). For the purposes of the PEA and valuation, a long-term average price of US$3,780/t HPMSM has been used from 2030.

Metallurgical processing reagents and raw materials constitute the largest component of processing expenditure based on the plant design criteria and flowsheet to produce HPMSM. During 2021 and early 2022, Covid-19 related disruptions led to an unprecedented rise in international freight rates, which elevated prices for the procurement of reagents. These rates have continued to normalize since then towards pre-Covid levels and updated reagent and raw materials prices have been incorporated into the PEA to reflect international freight market conditions as of June 2023.

For the calculation of applicable local taxes, the PEA assumes a dual-taxation structure for Menzi, split between a mining company and a manufacturing company. The mining company will mine and sell manganese oxide material to the manufacturing operation and will be taxed according to the Botswana mining company tax formula (minimum of 22% on operating income with a maximum of 55%). A mining royalty of 3% will be applied to the revenue on the sale of the manganese material to the manufacturing operation. Income from the manufacturing company will be taxed at the Botswana manufacturing tax rate of 15%, assuming a manufacturing development order will be received from the Botswana authorities.

The reader is advised that the PEA summarized in this press release is preliminary in nature and is intended to provide an initial, high-level review of the Project's economic potential and design options. The PEA replaces and supersedes the Company's previous 2022 Feasibility Study on the Project. The PEA mine plan and economic model includes numerous assumptions and the use of Inferred Resources. Inferred Resources are considered to be too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Project Execution and Optimized Feasibility Study

The release of the updated MRE and new PEA for K.Hill highlights the inherent value of the Project and the importance of the continuing activities related to the development of the commercial Project. The Company is progressing with various critical workstreams to move the Project to a final investment decision (“FID”), namely:

  • Construction and commissioning of the Demo Plant in Johannesburg, which will be capable of producing up to 600 kg per day of dry HPMSM crystals for shipment to off-takers for product qualification and contractual negotiation.
  • Advancing discussions with the multiple Tier-1 off-takers who have expressed interest in bringing K.Hill into their battery raw material supply chains, a number of whom have already visited Giyani’s facilities. These discussions will be enhanced by the increased LOP and potential scale of production, which are key requirements for the long-term outlook taken by off-takers.
  • Finalization and approval of the EIS following comments received from the DEA, which will facilitate Environmental Authorisation of the Project and open the door to an application for a 25-year mining licence.
  • Continuation of discussions with the Special Economic Zone Authority of Botswana with regards to establishing a Special Economic Zone around the K.Hill processing plant, which, among other benefits, establishes a corporation tax rate of 5% for the first 10 years of production and 10% thereafter. This regime has not been utilized within the PEA.
  • Review of various optimization parameters including operating costs, specifically related to consumption of key reagents, where the Company is assessing options to reduce consumption of certain higher value reagents and/or localize sourcing (over-the-fence production) to limit transport costs and develop local business opportunities.

The results of some of these workstreams will be incorporated into an Optimized Feasibility Study based on the updated MRE for K.Hill, which will form the basis for a future FID. Work on the Optimized Feasibility Study is expected to commence in Q4 2023.

This release also contains references to estimates of mineral resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may have to be re-estimated based on: (i) fluctuations in mineral prices; (ii) results of drilling, (iii) metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licences or changes to existing mining licences.
