Kaiser Reef (ASX:KAU) has announced a production milestone as well as ongoing progress at the A1 mine and Maldon processing plant in Victoria, including pouring its 100th gold bar.

Kaiser Reef says it continues to progress towards stable and longlife operations supported by deep drill intercepts, including 69g/t gold at 115m below the current level of operations, and 50m below the deepest known workings.

The company also highlighted the replacement leach tank and direct drive agitator installed at Maldon is increasing efficiency and operational availability.

Kaiser Reef says remote controlled and non-remote loaders have also been purchased to increase production capability.
