Montreal, Quebec, Canada, March 29, 2023 – Manganese X Energy Corp. (TSXV:MN) (FSE: 9SC2) (OTC: MNXXF) (“Manganese X” or the “Company”) is pleased to announce initial results from its recently completed pre-feasibility diamond drilling program at the Company’s 100% owned Battery Hill project located near Woodstock, New Brunswick, Canada. The program consisted of infill and expansion drilling designed to upgrade existing inferred resources to the measured and indicated categories in support of the project’s upcoming Pre-Feasibility Study (PFS).

Assays have been received from 10 holes of the 35 hole program, drilled on the Moody Hill and Sharpe Farm sectors of the Battery Hill deposit. See Figure 1 for a plan map with all drilling on the Moody Hill and Sharpe Farm sectors of the Battery Hill claims. Once all results have been received, an updated National Instrument 43-101 compliant mineral resource estimate will be completed.

Key Highlights (See Full Results in Table 1)

• 84 m of 12.8% MnO starting at surface, including 78 m of 13% MnO, in SF22-66
• 4 m of 11.2% MnO starting at 8 m, including 71.4 m of 11.4% MnO, in SF22-65
• 8 m of 14.6% MnO starting from 4.2 m, including 31.8 m of 19% MnO, in SF22-63
• 5 m of 12.28% MnO starting at 5.5 m, including 40.8 m of 15.7% MnO, in SF22-64
• 26 m of 13.3%MnO starting at 69 m in hole SF22-59
• 20 m of 14.7% MnO starting at 92 m in hole SF22-60

Manganese X CEO Martin Kepman commented, “We are very pleased with the progress made on our Battery Hill prefeasibility drilling program, having just completed 35 infill drill holes measuring 4,690 meters, especially given the harsh winter conditions. Today we are reporting on our first 10 drill holes and are very satisfied with the strong results. The remainder of the infill drill holes are currently at the laboratory for analysis.”

He continued, “It’s important to note that the PFS is key to the decision making and forward planning of the mine permitting process, as well as the de-risking and advancement of our Battery Hill project. A major part of preparing for the PFS is our current drill program, as well as the environmental, community and geotechnical studies, which will commence in the spring.”

Pilot Plant Project Update

Manganese X CEO Martin Kepman also stated, “In addition, our pilot plant project at Kemetco Research Inc. located in Richmond, BC, is proceeding well. We anticipate that we will be able to send out high purity EV compliant manganese sulfate monohydrate products to interested parties from the EV battery sector in the coming weeks to initiate the validation process. More information to follow.”

The Company is methodically fulfilling its mission to become the first publicly traded mining company in Canada and the United States to commercialize high-purity electric-vehicle compliant manganese.

Holes SF22-63 to 65 were vertical holes, drilled at a low angle to the strata, and provided material for testing in the ongoing Pilot Plant testing at Kemetco Research, in Richmond, BC. Holes SF22-59 to 62, and SF22-67, were drilled at 45 degrees and have an estimated true thickness of 80-85% of reported values.

Standard protocols and industry standard practices were employed in logging and sampling the core. QA/QC practices included insertion of Certified Standards, blanks and duplicates, each consisting of 5% of the total samples. Check assays of 5% of the samples are being sent to a second laboratory. Samples averaged 2 metres in width. All initial half-core samples were taken by Company personnel to the Actlabs prep lab in Fredericton, New Brunswick, where they were prepped and the pulps forwarded to Actlabs in Ancaster, Ontario, where XRF-Fusion Whole Rock Analysis (Code 4C) was performed. Actlabs is an accredited analysis laboratory.
