Manganese X’S High Purity Manganese Passes Phase 1 of US Battery Leader C4V Supply Chain Qualification Program

Corporate Updates

MANGANESE X’S HIGH PURITY MANGANESE PASSES PHASE 1 OF US

BATTERY LEADER C4V SUPPLY CHAIN QUALIFICATION PROGRAM

Montreal, Quebec (June 6 , 2024) – Manganese X Energy Corp. (TSXV: MN) (FSE: 9SC)

(TRADEGATE: 9SC) (OTCQB: MNXXF) (the “Company” or “Manganese X”) is pleased to

report its High Purity Manganese (HPMSM) sample has met US Battery Leader C4V’s Phase 1

commercial level qualification compliance standards for the Electric Vehicle (EV) Battery Cathode,

and is moving immediately to the next round of rigorous testing in C4V’s Supply Chain

Qualification Program.

Manganese X CEO Martin Kepman commented, "Achieving this milestone brings us one step

closer to becoming the first publicly traded mining company in Canada and the US to

commercialize high-purity, EV-compliant manganese. We are excited to enter Phase 2 of testing

with C4V, moving us closer to a potential offtake agreement. This partnership is truly synergistic.

Manganese X is dedicated to qualifying our Battery Hill manganese to be a reliable, high -quality

domestic supplier for C4V as they strengthen their supply chain through this comprehensive

Qualification Program."

Manganese X’s HPMSM Phase 1 testing was conducted in -house at lab scale through C4V’s

Digital DNA Supply Chain Qualification Program. The Supply Chain Qualification Program

consists of three phases and is an important aspect of the non -binding Memorandum of

Understanding the companies signed in early 2024, leading to a potential offtake deal from

Manganese X's Battery Hill Manganese mining project in Woodstock, New Brunswick, Canada.

Battery Hill contains one of the largest manganese carbonate deposits in Canada and the US.

To summarize the results of C4V’s Phase 1 testing, Manganese X’s sample demonstrated that

electrodes could be calibrated and that while testing its rate, performance and capacities , these

met the standards required. Capacities and performance of the sample also appeared stable

during long cycling.

The next Phase to be conducted, Phase 2, will be to validate that Manganese X’s sample meets

standards for long cycling performance and capacity retention of the cells.
