Manganese X Reports Positive Phase 2 ORE-Sorting Results — Achieving 80% Mill Feed Upgrade Improvement — Projected to Reduce Capital and Operating Costs
MANGANESE X REPORTS POSITIVE PHASE 2 ORE-SORTING RESULTS —
ACHIEVING 80% MILL FEED UPGRADE IMPROVEMENT — PROJECTED TO
REDUCE CAPITAL AND OPERATING COSTS
Key Highlights
Pilot scale results indicate Battery Hill material is very amenable to ore sorting:
• Mill feed grade can be increased by 80%.
• Testing was conducted with full size production equipment, not lab scale.
• By increasing mill feed grade, ore sorting is projected to positively impact
CAPEX, OPEX, and production cost per tonne, leading to enhanced Project
economics.
• Discussions underway to integrate ore sorting into the Battery Hill Pre -
Feasibility Study (“PFS”) program.
Montreal, Quebec – August 12, 2025 – Manganese X Energy Corp. (TSXV: MN) (FSE: 9SC)
(TRADEGATE: 9SC) (OTCQB: MNXXF) (the “ Company” or “ Manganese X ”) is pleased to
announce highly positive Phase 2 ore-sorting results, demonstrating an 80% increase in mill feed
grade in its large scale Battery Hill pilot program, managed by ABH Engineering.
An 80% increase in mill feed grade means that, after ore-sorting, the material sent to the mill
contains 80% more manganese per tonne than the original mined material.
The ore-sorting program was performed at RADOS Technologies lab in South Africa where over
400kg of rock from the Company’s Battery Hill manganese deposit near Woodstock, New
Brunswick, was processed. The sample was split into two size fractions and tested using full-scale
production equipment. Through ore sorting, waste rock was effectively removed, pre -
concentrating the rock before further processing.
This ore-sorting process is also projected to deliver significant capital expenditure (CAPEX) and
operating cost (OPEX) savings, potentially supporting a strong outcome in the Company’s
upcoming PFS.
Results confirm that Battery Hill material is highly amenable to ore -sorting, enabling substantial
improvements in feed grade while providing significant potential capital and operating costs
savings.
The study was conducted in preparation for the Company’s PFS, scheduled to commence in Q3
2025. Manganese X is having ongoing discussions with lead consultants regarding the integration
of ore-sorting into the Battery Hill PFS program.
CEO Martin Kepman commented , “We are highly encouraged by the results of this large -scale
pilot program, which confirm the economic potential of the ore -sorting technology we are
employing. These findings strongly support the viability of integrating this process into our
operations. By increasing mill feed grade, ore sorting is projected to positively impact CAPEX,
OPEX, and production cost per tonne.”
He continued, “With higher-grade feed, a smaller facility can produce more metal, while the ability
to create low -grade stockpiles enables very high upgrade ratios and maximizes resource
utilization. Potential benefits also include improved project NPV and IRR, reduced energy and
water consumption, expanded resources through cut-off grade reduction, and decreased tailings
storage requirements - along with the associated reduction in environmental impact.”
Brent Hilscher, VP of Mineral Processing at ABH Engineering, added, “The Manganese X results
are an excellent example of what we call a ‘clean sort’ or ‘sharp separation.’ The high-grade rock
can be easily concentrated with very high recovery rates. The impact of higher mill feed grade on
project economics can be profound.”
Ore-Sorting Details:
• Results are consistently positive between 10mm and 100mm feed sizes.
• Pilot plant used a large sample over 400kg.
• Testing was conducted on full size production equipment, not lab scale.
• Potential mill feed grades of 10% to 15% manganese (Mn) were achievable, with full scale
production equipment. Potential to stockpile medium grade rock by XRF system in single
stage three-way split.
