Valor Resources Ltd (ASX:VAL) has now commenced its second stage of metallurgical test work at its Berenguela Copper-Silver Project in Peru.
The processing flow sheet tested in the first stage recorded strong metallurgical recovery rates for copper 75-80%, silver 80-85% and manganese 85-90% from a 944-kilogram bulk sample.
The second stage of test work is expected to elevate the flow sheet to pre-feasibility study (PFS) level.
Valor’s chairman Mark Sumner said: “As previously announced, on 3 July 2018, the company has defined the process flow sheet, which is a significant development for the Berenguela project.
“The flow sheet utilises standardised process methods, providing a clear path to production of copper, manganese, silver and zinc.
“With this announcement, Valor is pleased to be able to add technical background to the flow sheet development, and to announce that the second stage has commenced, whereby variation in grade and mineralogy is being tested against optimal standard conditions.”

Valor is preparing for its 2018 diamond drill campaign at Berenguela which will include 19 holes for a total of 4,000 metres conducted at the borders of the Berenguela central deposit area.
Drilling will test extensions and high grade mineralised intercepts which were left open in the 2017 drill program and better define the vertical extent of the deposit.
