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:
- Excellent recovery of 95.7% Pb and 94.3% Zn metal
- 43.7% mass rejection of waste
- An overall enrichment ratio of 1.7 for both the lead and zinc
- Zn Equivalent (Pb+Ag) grade increased from 3.56% to 6.00%
• Results from hole TOD-025D revealed:
- Excellent recovery of 98.9% Pb and 94.7% Zn metal
- 46.8% mass rejection of waste
- An overall enrichment ratio of 1.9 for lead and 1.8 for zinc
- Zn Equivalent (Pb+Ag) grade increased from 6.57% to 12.00%
• Results from hole TOD-028 demonstrated:
- Excellent recovery of 96.6% Pb and 96.1% Zn metal
- 47.7% mass rejection of waste
- An overall enrichment ratio of 1.8 for both the lead and zinc
- 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.

Further work
Europa Metals has an ongoing work programme being undertaken by WAI, which
includes further sensitivity analysis on the preferred reagent suite and dry stack tailings
work combined with backfill/paste fill studies.
