Sumin holds a 26.66% interest in the Sandpiper Exploitation Concession. The concession has an area of 9,500 hectares and will expire March 20, 2025. Artisanal alluvial mining is widespread on the concession and there are reportedly gold-bearing quartz veins and a shallow scout drill hole reportedly intersected 3.03 g/t gold over 6.0 metres. None of these reported gold occurrences have been verified by the Company and no work is planned for the Sandpiper Gold Project.
