Successful Acid Leach Test Work Results at Zebediela
Initial metallurgical test work results reported 80% nickel
dissolution
URU Metals is pleased to announce the results of the nickel
leach test work programme on the Zebediela Nickel and PGE Project,
located in Limpopo, South Africa. Fresh material from the recent
drilling programme was submitted for acid leach test work to assess
the amenability of the Zebediela material to percolation leaching
with respect to nickel recovery and acid consumption.
Fresh material from diamond drill hole Z017 was submitted to
Mintek laboratory in Johannesburg, South Africa. Approximately 100
kg of the material was combined and all crushed to pass through 75
micron for iso-pH tests, agitated tank leach amenability tests and
chemical head and solid residue assays. Chemical assays where
performed by ICP-OES.
The oxidative acidic leach test work resulted in a dissolution
of 80% nickel after 26 days at a pH of 1.8 and the acid consumption
reached 447 kg/t. There will be a secondary process to recover the
nickel from the acid leach.
Figure 1 in the attached pdf file (please click on the below
link) illustrates the rate of nickel dissolution in the sample over
a period of days; Figure 2 illustrates the corresponding rate of
acid consumption over the same period.

The dissolution of 80% nickel is extremely positive for the
Project as it highlights the potential for acid leaching as a
processing method that could save on both capital and operational
costs. The Company intends to investigate this further, including
the recovery of the nickel from the acid leach.
Based on this result, the Company will proceed with the next
phase of metallurgical test work to investigate ways to reduce the
acid consumption further and demonstrate the feasibility of
leaching on mineralisation from the Zebediela Project.
John Zorbas, CEO of URU Metals, commented:
"The Company is delighted to report these acid leaching results.
We are encouraged by the high nickel dissolution that was achieved
in the first phase of the test work programme. Combined with the
increasing price of nickel, we look forward to the potentially
positive effect that the nickel leaching could have on the project
economics.
Due to nickel successfully dissolving in the solution, we are
now considering it as potentially a lower cost alternative to
building a flotation plant. The development of a leaching facility
could see a reduction in project capital expenditure. Our team will
continue to evaluate feasible project design options, and
additional leaching test work will continue to assess
cost-efficient leaching alternatives to improve dissolution."
