Manganese X Energy Corp. (TSXV: MN) (FSE: 9SC2) (OTC: MNXXF) ("Manganese" or the "Company") is pleased to announce the first Mineral Resource Estimate for its Battery Hill Manganese Project of 34.86 million tonnes of Measured and Indicated mineral resources grading 6.42% Mn, plus an additional 25.91 million tonnes of Inferred mineral resources grading 6.66% Mn. The mineral resource estimate was prepared in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (2014) and is tabulated in Table 1.

Table 1: Battery Hill Deposit Mineral Resource Estimate - Effective Date June 18th, 2021

Mineral Resource Estimate Notes:

1) Mineral resources were prepared in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (MRMR) (2014) and CIM MRMR Best Practice Guidelines (2019).
2) Mineral resources are defined within an optimized pit shell with average pit slope angles of 45⁰ and a 3.7:1 strip ratio (waste : mineralized material).
3) Pit optimization parameters include: pricing of US$1500/tonne for High Purity Manganese Sulphate Monohydrate - 32% Mn (HPMSM - 32 %), exchange rate of CDN $1.30 to US$ 1.00, mining at CDN $6.50/t, combined processing and G&A (1000 tpd) at CDN $86.22/t processed and a process recovery of Mn to HPMSM of 65%. Fe content was not included in the pit optimization.
4) Mineral resources are reported at a cut-off grade of 2.50 % Mn within the optimized pit shell. This cut-off grade reflects total operating costs used in pit optimization to define reasonable prospects for eventual economic extraction by open pit mining methods.
5) Mineral resources were estimated using Ordinary Kriging methods applied to 3 m downhole assay composites. No grade capping was applied. Model block size is 5 m (x) by 5 m (y) by 5 m (z)
6) Bulk density was applied using a regression curve based on Mn % and Fe % block grades.
7) Mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
8) Mineral resources are not mineral reserves and do not have demonstrated economic viability.
9) Mineral resource tonnages are rounded to the nearest 10,000.

Martin Kepman, CEO of the Company, states "This is game changing news for the Company, having such a large resource totalling 34.9 million Measured and Indicated tonnes and 25.9 million Inferred tonnes underwrites the project's long-term potential for supply of manganese. In addition, our ongoing metallurgical testing is making great strides toward achieving an economically optimized extraction process. We look forward now to the completion by Wood Canada Ltd. of a Preliminary Economic Assessment (PEA) for the project that will incorporate this new mineral resource estimate plus the latest metallurgical developments to provide important insight into the economic viability of producing high purity manganese sulphate from our Battery Hill deposit. We are buoyed by the knowledge that, with a positive outcome from the PEA, there appears to be sufficient tonnage of Measured and Indicated mineral resources to potentially sustain long term production while we explore the potential of the other Mn mineralization on our 1228-hectare property. The EV revolution is well underway and innovative battery chemistry is a large part of the disruption. We believe manganese will have a large influence over EV batteries going forward. Our Battery Hill property could potentially have a long-life cycle, estimated at 25 years based on the Measured and Indicated Resource, and potentially service the EV sector for years to come within the North American and European supply chain"

The Company has undertaken several core drilling programs over the past 5 years that support the current mineral resource estimate. These include 53 holes totaling 9,697 metres over a deposit strike length of approximately 2.0 kilometres to arrive at this point. A diamond drilling program is being planned to expand Measured and Indicated mineral resources and to explore other known Mn showings on the 7 kilometer long MXE property.

The associated mineral resources now defined form the basis of the PEA being prepared by Wood Canada Ltd. The PEA will characterize and assess Commercialization and Economic Viability Potential for a future mining and processing operation at the Battery Hill Property.

The Battery Hill Deposit is comprised of the Moody Hill, Sharpe Farm, and Iron Ore Hill Zones. On a contained tonnage basis the Moody Hill, Sharpe Farm, and Iron Ore Hill Zones comprise approximately 56%, 29%, 15%, respectively, of the Battery Hill Deposit mineral resource. The Moody Hill and Sharpe Farm Zones, just a few hundred meters apart (see Map, Figure 1), contain all of the Measured and Indicated mineral resources for the Battery Hill Deposit. The grade/tonnage sensitivity analysis that appears in Table 2 provides insight into the character of Mn mineralization present within the Battery Hill Deposit over the cut-off grade range of 2.5% Mn to 7% Mn. Although iron (Fe) content has also been estimated and is currently reported for the deposit, only manganese content was used in the pit optimization process. The Company will further assess Fe by-product opportunities through future metallurgical studies.
