Work on the plant commenced in October 2014 and is on schedule for completion in March this year.
The company completed primary, secondary and tertiary crushing of 3,300 tons of ore and waste, rehabilitation of areas where ore and waste rock samples were sourced from, civil construction of four cribs and plinths to support the agglomerator and feed conveyors, reagent mixing area and two evaporation ponds.
Installation of the crib access steps and walkway, agglomerator, the water, acid and electrical reticulation and ore feed conveyor system is underway.
Bannerman CEO Len Jubber said: "The construction of the demonstration plant has generated significant interest from all major stakeholders and is widely recognised as a clear sign of our commitment to develop the Etango Project in a higher uranium price environment.
"The timing of the first test results in the June 2015 quarter coincides well with the growing awareness of the looming supply deficit."
