G Mining Services Inc of Montreal, in collaboration with SGS, also estimated resources within a Whittle-optimized pit shell using a base case gold price of US$1,400 per ounce and pit limits that are unconstrained by lakeshores. The optimization yielded two distinct pits separated by approximately 200 metres with an average strip ratio of 1.01. The total in-pit M&I resource for the Hammond Reef gold deposit is 5.31 million ounces of gold at an average undiluted grade of 0.72 g/t Au, based on a derived lower cut-off grade of 0.31 g/t Au (west pit) and 0.33 g/t Au (east pit).
