Canstar Resources Inc. is a Canadian mineral exploration and development company engaged in the business of exploring for mineral deposits, primarily gold and base metals. It's flagship property is the Mary March Project, located in central Newfoundland, 20 km northeast of, and within the same geological group that hosts the former producing Buchans Mine. Discovery holes drilled in 1999 and 2000 produced some of the highest grade base and precious metal intersections ever achieved in the area outside the Buchans mine.
