EnviroGold Global Limited announced the successful completion of initial test work for its Smelter By-Product Project with a major global metal production company. The initial test work, conducted by inhouse team of experts, in conjunction with Brisbane Metallurgical Laboratories in Brisbane, Australia, focused on optimizing copper, silver, lead, zinc, and iron recovery from the smelter by-product, which results from previous metal processing operations. The results demonstrate another step change in efficiency in extracting critical metals from these by- product materials.

The test results confirmed excellent liberation of critical and precious metals using EnviroGold Global's proprietary hydrometallurgical process (NVRO process) and support moving to phase 2 testing. The company reported the initial test results on a leach of the smelter by-product showed a strong oxidation rate and recovered very high levels of metals. The value of the current feed to the NVRO process is estimated to be over USD 900/tonne (based on current LME pricing).

The team will complete additional work to further understand and improve the silver recoveries.
