The Hackett River property is located in Nunavut, Canada, approximately 480 km northeast of Yellowknife. Hackett River is a silver-rich volcanogenic massive sulphide project and is one of the largest undeveloped projects of its kind. The property is made up of four massive sulphide deposits that occur over a 6.6 km strike distance.
A preliminary economic assessment updated in 2010 evaluated a possible large-scale open pit and underground operation, processing up to 17,000 tonnes per day. The most recent Technical Report, completed in 2013, contained a mineral resource estimate prepared by Sabina Gold and Silver Corporation, with technical support from Xstrata Canada Corporation, now Glencore plc. The updated resource reported 25.0 million tonnes of indicated resources containing 4.2% zinc and 130.0 g/t silver plus 57.0 million tonnes of inferred resources with 3.0% zinc and 100.0 g/t silver.
Sandstorm has a 2.0% NSR royalty that covers 7,141 hectares of the Hackett River property including the licenses where the mineral resources have been defined. Sandstorm acquired the royalty as part of a transaction with Teck Resources Ltd. in January 2016.
