Positive Ore Sorting Results for the Toral Pb, Zn & Ag
Project, Spain
Europa Metals, the European focused lead, zinc and silver
developer, is pleased to announce positive results in respect of
the X-Ray Transmission ("XRT") ore sorting testwork, carried out by
TOMRA GmbH ("TOMRA") in Germany and overseen by Wardell Armstrong
International Ltd ("WAI") in Cornwall.
A bulk sample of siliceous mineralisation and two further
discrete carbonate samples (from holes TOD-025D and TOD-028) from
the indicated mineral resource zone at the Company's wholly owned
Toral lead, zinc and silver project in the Castilla y León region,
Spain ("Toral" or the "Toral Project") were evaluated by TOMRA. The
XRT testwork forms part of a wider metallurgical programme that
includes locked cycle flotation testwork and tailings evaluation
for backfill.
Highlights :
-- Results from the siliceous bulk sample showed:
o Excellent recovery of 95.7% Pb and 94.3% Zn metal
o 43.7% mass rejection of waste
o An overall enrichment ratio of 1.7 for both the lead and
zinc
o Zn Equivalent (Pb+Ag) grade increased from 3.56% to 6.00%
-- Results from hole TOD-025D revealed:
o Excellent recovery of 98.9% Pb and 94.7% Zn metal
o 46.8% mass rejection of waste
o An overall enrichment ratio of 1.9 for lead and 1.8 for
zinc
o Zn Equivalent (Pb+Ag) grade increased from 6.57% to 12.00%
-- Results from hole TOD-028 demonstrated:
o Excellent recovery of 96.6% Pb and 96.1% Zn metal
o 47.7% mass rejection of waste
o An overall enrichment ratio of 1.8 for both the lead and
zinc
o Zn Equivalent (Pb+Ag) grade increased from 4.24% to 7.67%
Commenting today, Myles Campion, acting CEO and Executive
Chairman of Europa Metals, said :
"These latest positive results from TOMRA form part of our
ongoing metallurgical work programme for 2022 and enhance the
potential to efficiently exploit the resource at Toral. These
results build on previous testwork results (announced on 28 August
2020) and demonstrate the potential for further optimisation of the
Toral Project."
Details of the Samples Tested
WAI is currently undertaking a work programme on metallurgical
samples submitted by Europa Metals, representing the expected ore
types from Toral: a >700kg bulk sample of siliceous
mineralisation and two separate carbonate samples from holes
TOD-025D and TOD-028.
The three samples submitted to WAI for testing represent the two
different styles of mineralisation expected to be encountered
during potential future production at Toral. Further details of the
representative samples are set out in Table 1 below:
1. Siliceous mineralisation from holes TOD-029 and TOD-034 and
their respective daughter holes (TOD-029D, TOD-029D2 and TOD-029D3
and TOD-034D)
2. Carbonate sample from hole TOD-025D
3. Carbonate sample from hole TOD-028

The upgraded products from the ore sorting are now progressing
into flotation testing.
Summary of Ore Sorting
During 2020, Europa Metals tested XRT ore sorting on lower grade
mineralisation that had not been considered in the 2018 Scoping
Study. Further to the successful testwork and a positive 2021
drilling campaign, a bulk sample was submitted to WAI with a view
to enhancing the project's parameters, including:
-- Enabling ore that may otherwise be sub-economic based on grade to be processed;
-- Reducing the size of the concentrator plant (milling and
flotation circuits) whilst maintaining the same overall mining
rate;
-- Improving the performance of the concentrator plant by removing waste from the feed; and
-- Allowing higher mining rates without necessarily having to
increase the size of the processing plant.
The sorting results for all the samples submitted are considered
to be excellent, with between approximately 43% - 48% of the mass
rejected at >95% Pb recovery and >94% Zn recovery. The
resulting enrichment ratios are generally >1.7, in regard to the
feed grade to milling and flotation.
Toral Ore Sorting Analysis
The results are presented in detail in Table 2 below. Overall,
the data showed that in excess of 94% of the overall lead and zinc
in the feed could be recovered whilst rejecting more than 43% of
the original mass.
The "sorted" product will now go into a series of flotation work
programmes with WAI.
