Mantle Mining Corporation Announces Improved Confidence Levels for Granite Castle Resource
Mantle Mining Corporation advised that an upgraded resource estimate has recently been completed for the Granite Castle Project by Dr William Yeo MAusIMM. A summary of the underlying data and the methodology used for the resource estimates is appended to this announcement. Resource estimates of both gold and silver, from the 690m RL to the 540m RL have been produced for the Granite Castle Deposit, and are in total: 847,078t, 2.91g/t Au, 79,301oz Au, 56.2g/t Ag, and 1.53Moz Ag (Estimates @ 0.2g/t Au); and 764,704t, 3.14g/t Au, 77,210oz Au, 61g/t Ag, and 1.50Moz Ag (Estimates @ 1g/t Au). Also, at a gold equivalent conversion of 55g/t Ag for 1g/t Au, silver contributes an additional 1g/t Au-equivalent to the gold resource grade estimate.
