2021 HIGHLIGHTS

In early 2021, the Company engaged Mercator Geological Services Limited to update its 2014 technical report on the Woodstock Project in an updated National Instrument 43-101 Technical Report, including preparation of a revised resource estimate, assuming the production of high purity manganese sulphate monohydrate ("HPMSM") and updated economic assumptions.

On April 30, 2021, the Company completed its acquisition of Maximos Metals Corp. ("Maximos") and a concurrent $6.2 million equity financing.

On May 5, 2021, the Company appointed Matthew Allas as President and Chief Executive Officer. Previously, Mr. Allas had been President and Chief Executive Officer of Maximos since 2018.

Throughout 2021, following the completion of the reassessment of strategic focus from the production of Electrolytic Manganese Metals ("EMM") to HPMSM, including current pricing analysis and preliminary operating cost estimates, the Company worked with its consultants on the preparation of the updated Technical Report, and expanded its engagement efforts with stakeholders of the Woodstock Project, including the Government of New Brunswick and local First Nations communities.

In December 2021, the Company filed its updated Technical Report prepared in accordance with National Instrument 43-101, reporting an updated Mineral Resource Estimate for the Plymouth manganese-iron deposit at Woodstock. The new Mineral Resource estimate, which was prepared in accordance with the CIM Definition Standards for Mineral Resources and Reserves as amended in 2014 (CIM Standards 2014), now stands at 43,070,000 tonnes grading 10.01% manganese (utilizing a cut-off grade of 5% Mn) in the Inferred category.

The updated Technical Report noted that well defined opportunities to expand the current mineral resources exist in the immediate strike and dip extension areas of the mineralized zones that comprise the currently defined deposit and that the nearby, historically explored Hartford Mn-Fe deposit has good potential for definition of new mineral resources.
