Get to know us

Marsole Holdings is a Canada-based strategic investment and development firm headquartered in the Greater Toronto Area. Our mission is to bridge global industries with critical mineral resources, advanced financing frameworks, and high-impact development opportunities that shape the future of infrastructure, technology, and sustainability.

Our business spans multiple sectors, with a strong focus on mineral sourcing, infrastructure collaboration, energy-related initiatives, and strategic export facilitation. We maintain a global network of trusted partners, allowing us to structure cross-border ventures that align capital with real-world needs and long-term industrial value.

One of our key areas of activity involves the export of refined industrial minerals. Working closely with high-quality manufacturers in China, we facilitate the global distribution of materials such as graphitized recarburizer, synthetic graphite, flake graphite, and calcined petroleum coke. These resources are supplied in accordance with strict international standards, ensuring consistency and reliability for clients across North America, Europe, and Latin America.

In the field of medical technology, we support the international export of Japan’s BNCT (Boron Neutron Capture Therapy) system, a next-generation cancer treatment platform developed with compact design and patient safety in mind. Utilizing a high-current proton accelerator and a carefully engineered neutron generation system, the BNCT device is tailored for integration into hospital environments and advanced therapeutic programs.

Marsole also plays a role in facilitating the export of advanced defense technologies to trusted partners in Eastern Europe and beyond. This includes systems related to precision motion control, drone detection and countermeasure devices, radar-based surveillance, modular ground vehicle equipment, and other tactical technologies developed for modern defense environments.

In addition to exports, we are actively pursuing participation in mining development projects in Eastern Europe. We are working closely with Canadian government agencies and mining companies to identify opportunities for strategic mineral development through responsible investment and international cooperation.

At Marsole Holdings, we believe in building long-term, value-driven relationships by aligning resources with opportunity. Whether in minerals, healthcare, defense, or infrastructure, our commitment is to serve as a reliable global partner—connecting regions, technologies, and institutions through meaningful collaboration.
