Hummingbird Resources, the Liberian gold exploration and development company, has released the results of its extensive metallurgical test work carried out as part of its Detailed Feasibility Study (DFS), which show increased recovery rates across the Tuzon deposit.
The results reveal 90% recoveries at Tuzon, which is up from 88% in the PEA. Cyanide consumption has been reduced from 0.9 kg/t to 0.3 kg/t as a result of lead nitrate addition. Hummingbird Resources confirmed that recoveries are a significant driver of improved project economics.
“Improvement to recovery in the metallurgical test work marks another important step in our optimization of the project and progress towards completion of the DFS. Building on the work done for our PEA we are very pleased that following further comprehensive test work an increase in recoveries to 90% across the Tuzon deposit has been achieved. The company remains fully funded beyond DFS,” said Hummingbird Resources CEO Dan Betts.
