Rockhaven Resources has leading all-in sustaining costs
Rockhaven Resources's Klaza could potentially be placed within the leading group of gold mines measured by all-in sustaining costs.
The analysis by Kitco is based on the Rockhaven's (TSX.V:RK) preliminary economic assessment published in 2020. See chart below showing global gold production cost curve based on AISC in Q2 2020. The red horizontal line indicates the first quartile.
According to Rockhaven's preliminary economic study of Klaza completed in 2020, life of mine cash costs are cash costs of $613/oz AuEq, and the all-in sustaining cost is $875/oz AuEQ. At $1450/oz gold and $17/oz silver and an exchange rate of CAD/USD 0.72, the project hosts an attractive C$378 million post tax NPV(5%) and 37% IRR.
The Klaza deposit is still at the project phase with excellent exploration potential to continue to add ounces to an already impressive resource base. Further exploration and definition drilling will continue in 2021 with the idea of launching into pre-feasibility in 2022. The project hosts one of the highest-grade gold deposits ever discovered in Yukon. Rockhaven owns 100% interest in the deposit and controls over 250 square kilometres of prospective land within the district.
