About Adex Mining Inc.

Adex Mining Inc. is a publicly traded Canadian mineral exploration and development company headquartered in Toronto, Ontario. The company trades on the TSX Venture Exchange (TSXV) under the ticker ADE and is focused on advancing its flagship asset, the Mount Pleasant Mine property in Charlotte County, New Brunswick. Mount Pleasant is described as one of North America's most significant polymetallic mineral assets, supporting Adex's position in the expanding strategic and critical minerals space.

Flagship Property & Mineral Zones

Adex controls 100% of the subsurface mineral rights across approximately 1,600 hectares at Mount Pleasant. The property is defined by two major mineralized zones that anchor its potential. The North Zone contains tin, indium, and zinc, while the Fire Tower Zone hosts tungsten and molybdenum mineralization. These metals are closely tied to modern industry-tin and indium support electronics and display technologies, and tungsten and molybdenum are widely used in automotive, energy, and manufacturing applications.

Infrastructure Advantage

A notable advantage of the project is its existing infrastructure, including underground workings, surface facilities, and utility access, which can help reduce development complexity compared to greenfield sites.

Adex Mining Inc. was founded in 1992 and has operated as a Canadian mineral exploration and development company with a clear focus on building value through strategic mineral assets. Over the years, Adex has maintained its public market presence while concentrating its efforts on advancing its flagship Mount Pleasant Mine property in New Brunswick.

The company's long-term approach has centered on advancing exploration work, improving the technical understanding of the asset, and continuing project-level efforts that support future development and value creation. By holding the property and progressing work over time, Adex has positioned Mount Pleasant as the core asset shaping its overall direction.

As market attention has increased toward strategic and critical minerals, Adex has remained aligned with metals that support modern technology and industrial demand-strengthening the relevance of Mount Pleasant within the company's broader growth and value strategy.

Adex Mining Inc.'s operations are centered on the Mount Pleasant Mine property in Charlotte County, New Brunswick. The company holds 100% of the subsurface mineral rights across approximately 1,600 hectares, giving it full control of the mineral potential within the property boundaries.

Mount Pleasant is a polymetallic project supported by two major mineralized zones. The North Zone is associated with tin, indium, and zinc mineralization, while the Fire Tower Zone hosts tungsten and molybdenum mineralization. This mix of metals supports Adex's positioning in resources linked to both industrial and technology-related applications.

A key advantage highlighted for Mount Pleasant is the presence of existing site infrastructure. The property includes historical underground mine workings, along with surface facilities and access to utilities. These features can reduce early-stage development challenges and provide practical logistical advantages compared to projects that require brand-new infrastructure from the ground up.

Adex Mining Inc. continues working to unlock the full value of the Mount Pleasant property through ongoing exploration and project evaluation, continued technical studies, and the review of strategic alternatives aimed at maximizing shareholder value. This direction reflects growing market interest in critical minerals and the importance of metals that support modern technology and industrial applications.

In 2025, Adex engaged Moneta Securities Inc. to lead a structured sale process for the Mount Pleasant asset. This action signals meaningful interest from both domestic and global groups seeking strategic minerals exposure and shows Adex's active approach to evaluating opportunities related to the project.

Alongside this strategic review, Mount Pleasant's existing infrastructure-underground workings, surface facilities, and utility access-remains an important part of its development profile. Adex's focus remains on progressing the asset in a way that supports strong potential outcomes while aligning with its stated commitment to responsible and sustainable mining practices.
