This metallurgical testwork has provided us with additional confidence in our ability to incorporate the Malartic H deposit into a potential Marban Alliance mine plan."

The metallurgical testwork was conducted to assess the initial potential gold recoveries for the deposit. The program included head characterisation, comminution testing, gravity, cyanide leach testing, cyanide detox, oxygen uptake, solid/liquid separation, and rheology tests.

Comminution results showed, moderately soft to medium hardness with bond ball mill work index ranging from 12.5 to 14.1 with an average of 13.5 kWh/t.
