I've just been refreshing my memory of where we are to date with the metallurgy as we wait for the final phase so I thought it might help everyone to share this brief summary. From the third phase……..
· Recovery and grade results are believed by Europa Metal's Board to be significantly above average versus concentrates available in the current market, with the lead concentrate grade (combined to a cleaner+scavenger product), considered by the Board, to rank amongst the highest concentrate grades globally;
· Excellent grade and recovery results from metallurgical sample TOD-025H, comprising:
o 83.9% Pb recovery to a 79.2% Pb concentrate;
o 87.7% Ag recovery to 512ppm Ag within Pb concentrate; and
o 87.7% Zn recovery to a 60.0% Zn concentrate. (In the second phase metallurgy this was 77% just to illustrate how it’s been progressive).
This is all we know on deleterious elements so far……
"Importantly, the concentrates are free from a number of deleterious elements otherwise present in concentrates from the region, including iron, arsenic and bismuth. Additional testing has therefore been recommended by WAI to confirm the existence or otherwise of such deleterious elements across other parts of the deposit and, if present, to consider potential methods with which to limit or mitigate their impact".
