Greencastle Resources Ltd. is a diversified Canadian company specializing in the exploration and development of natural resources. Its core activities span gold and base metals exploration as well as oil and gas exploration and royalty interests. The company’s portfolio is composed of three primary segments: direct investments in private and public companies, mining interests across Canada and the United States, and oil and gas interests, including royalty holdings in producing regions of Alberta and Saskatchewan. Greencastle Resources also maintains strategic holdings in other resource-focused companies, such as Deveron Corp. and Highrock Resources Ltd., and was an early-stage investor in Criterium Energy Ltd. This multi-sector approach enables the company to participate in the growth of both the mining and hydrocarbons industries, leveraging royalties, operating interests, and equity positions. With a history dating back to 1996, Greencastle Resources plays a role in supporting resource development and investment in North America, balancing direct exploration activities with broader investment exposure within the resource sector.
