Hole TOD-025 and Wedge Completed, Toral Pb, Zn, Ag Project, Spain
Europa Metals, the European focused lead-zinc and silver developer, is pleased to provide a drilling update in
respect of its wholly owned Toral lead, zinc and silver project (“Toral” or the “Toral Project”) situated in the
region of Castilla y León, north west Spain.
• Drill hole TOD-025 completed;
• Visual review of intersected mineralisation resulted in a decision to drill beyond the original target depth
of 420 metres to 497 metres;
• Opportunity identified to drill a wedge, TOD-025D, which has been completed;
• Company targeted the highest grade areas of Toral, based on the pre-existing JORC (2012) mineral
resource estimate and block model, with this diamond drilling campaign which has now been concluded;
• Core samples to be sent for independent assay, with the results expected to be announced later in Q1
The Company is pleased to announce that the drilling of hole TOD-025 has been completed, with a wedge,
TOD-025D, also being drilled off the parent hole which concludes the latest drilling campaign. Core samples
obtained from both holes TOD-025 and TOD-025D, and the previously drilled hole TOD-024, will shortly be
sent for independent assay.
Further to visual review of mineralisation intersected during the drilling of hole TOD-025, a decision was made
to continue drilling beyond the original target depth of 420 metres to 497 metres. On completion of this hole,
the opportunity was taken to immediately commence a wedge from the parent hole, which has now been
successfully concluded at a depth of 500 metres. As previously announced, the independent assay results
from this latest drill programme are expected to be received and announced later in Q1 2020.
Holes TOD-024, TOD-025 and TOD-025D are located in the highest grade areas of the Toral Project, to the
west of the current Indicated JORC (2012) mineral resource estimate and within the global (Inferred) resource
zone. These holes have targeted areas to infill between historic drill holes and within areas of specific interest
to the Company located inside the higher grade zones of the deposit.

Appendix: Further information on the Toral Project
JORC (2012) Mineral Resource Estimate
The Toral Project is a traditional polymetallic (lead-zinc-silver) deposit, which is hosted over 6km of strike length of the
prospective Lower Cambrian Vegadeo Limestone formation, that is regionally mineralised along more than 40km of its
extent. The deposit represents a carbonate hosted, structurally controlled deposit type, demonstrating fault-controlled
contact, vein, carbonate replacement and breccia styles of mineralisation situated close to and along the boundary between
footwall slates and hanging wall limestones and dolomites. Sub-ordinate lead-zinc-silver mineralisation also occurs wholly
within the hanging wall limestones and dolomites, approaching the contact with the slates.
Historic drill hole re-logging undertaken by the Company in 2018 provided improved geological, structure, alteration and
weathering/oxidation information, which was incorporated into the interpreted geological and mineralised models for the
current JORC (2012) mineral resource estimate. Surface mapping and remote data interpretation by Europa Metals has
enabled the development of an interpreted fault model, also incorporated into the aforementioned updated geological and
mineralised models used in the mineral resource estimate.
The latest mineral resource estimate (as of 25 October 2019) for the Toral deposit comprised, at a 4% cut-off:
• An Indicated resource of approximately 2.7Mt @ 8.9% Zn Equivalent (including Pb credits), 5% Zn, 4.2% Pb and
o Including 130,000 tonnes of zinc, 110,000 tonnes of lead and 2.8 million ounces of silver
• An Inferred resource of approximately 16Mt @ 7.2% Zn Equivalent (including Pb credits), 4.5% Zn, 2.9% Pb and
o Including 690,000 tonnes of zinc, 450,000 tonnes of lead and 11 million ounces of silver
• Total Resources of approximately 18Mt @ 7.4% Zn Equivalent (including Pb credits), 4.5% Zn, 3.1% Pb and 24g/t
o Including 830,000 tonnes of zinc, 570,000 tonnes of lead and 14 million ounces of silver
The latest resource update identified potentially economic mineralisation ranging from surface to approximately 1,100m
below surface. The block model currently extends for a strike length of 3,600m and is still open to the east and west along
strike and also at depth where it has not yet been closed off.

Table 2: Summary of mineral resources for the Toral property reported at a 4.0% Zn equivalent cut-off grade (including Pb and Ag
credits) and estimated grade and tonnages at the various cut-off grades. Figures are rounded to reflect the accuracy of the estimate and
as such totals may not cast.
1. No mineral reserve calculations have been undertaken. Mineral resources that are not mineral reserves do not have demonstrated
2. Numbers are rounded to reflect the fact that an Estimate of Resources was reported as stipulated by JORC 2012. Rounding of
numbers may result in differences in calculated totals and averages. All tonnes are metric tonnes.
3. Zn equivalent calculations were based on 3 year trailing average price statistics obtained from the London Metal Exchange and
London Bullion Market Association giving an average Zn price of US$2,780/t, Pb price of US$2,200/t and Ag price of US$16.4/oz.
Recovery and selling factors were incorporated into the calculation of Zn Eq values. It is the Company’s opinion that all the elements
included in the metal equivalents calculation (Zinc, Lead and Silver) have a reasonable potential to be recovered and sold.
4. Zn Eq (PbAg)% is the calculated Zn equivalent incorporating silver credits as well as lead and is the parameter used to define the cut-
off grade used for reporting resources (Zn Eq (PbAg)% = Zn + Pb*0.935 + Ag*0.018).
5. Zn Eq is the calculated Zn equivalent using lead credits and does not include silver credits (Zn Eq = Zn + Pb*0.935).
6. The mineral resource estimate set out above for the zinc, lead and silver mineralisation in the Toral project area is based on a 3D
geologic model and wireframe restricted block model that integrated the exploration work on the Toral project up to 30 September
2019. The block model used uniform cell size of 50x4x50m to best suit the orientation of the mineralisation and sample spacing. The
block model was rotated by 20° in plan view to best match the trend of mineralisation. Sub cells were applied to better fit the wireframe
solid models and preserve accurate volume as much as possible. Cells were interpolated at the parent block scale using an ordinary
7. Top cuts were applied to the composite assay grades for 20% Zn, 17% Pb and 125 g/t Ag, any value above the top cut value was
reduced to that grade.
8. The Indicated and Inferred mineral resource category for the Toral lead-zinc-silver project set out in Table 2 (at cut-off grades ?4%
Zn Equivalent) comply with the resource definitions as described in the Australasian Code for the Reporting of Exploration Results,
Mineral Resources and Ore Reserves. The JORC Code, 2012 Edition. Prepared by: The Joint Ore Reserves Committee of The
Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia (JORC).
9. The tonnes and grades reported at a cut-off grade of 3% Zn equivalent are below the economic cut-off grade of 4% and as such
should not be considered mineral resources, they are shown here for comparison purposes only.
The resource database contains 2,373 bulk density measurements, with a total of 177 within the mineralised wireframe.
The mean for the mineralised domain transitional zone is 2.75 g/cm 3 and the mean for the mineralised domain fresh
material is 2.85 g/cm3. A broad linear relationship between Pb+Zn grade and bulk density was identified from scattergrams
and the formula 2.75 + 0.02(Pb+Zn%) used to estimate block density within the block model.
Preliminary independent metallurgical test results from Wardell Armstrong International (“WAI”) (December 2019).
Overview of sample and metallurgical testwork carried out by WAI:
• Grind calibration tests to assess the Bond Abrasion, Rod and Ball work indices and uniaxial compressive strength;
• First open flotation tests, optimisation of grind size, float cleaning tests and rougher regrind testing;
• Petrographic/mineralogical and scanning electron microscope (SEM) work;
• First/single locked cycle testing; and
• A series of comminution tests were undertaken to investigate the crushing and grinding characteristics of the
sample. The testing conducted investigated conventional crushing technologies, the results of which are
summarised in the following table:
Comminution Testwork Results
Comminution Test Units Value
Unconfined Compressive Strength (UCS) MPa 51.8
Bond Abrasion Index - 0.5227
Bond Rod Mill Work Index kWh/t 12.69
Bond Ball Mill Work Index kWh/t 9.83
A series of tests were undertaken to investigate the recovery of lead and zinc to separate concentrates by means of froth
flotation. The testing conducted consisted of: eight rougher flotation tests, four first-stage cleaner flotation tests, six three-
stage cleaner flotation tests and a single locked cycle flotation test.
The results of the locked cycle test are summarised below.

The locked cycle test achieved a lead recovery of 84.3% to a concentrate grading 57.5% Pb and a zinc recovery of 70.7%
to a concentrate grading 55.8% Zn. 90.3% of the silver was also recovered to the lead concentrate at a grade of 1,457ppm
Economic highlights from the Company’s selected development scenario
Estimated economic forecasts for the Toral Project based on the current level of work (+/-30%) from the Scoping Study
(December 2018) comprise:
• US$110 million net present value (NPV) using a discount rate of 8%;
• 24.4% internal rate of return (IRR);
• Estimated US$33 million CAPEX for a proposed 450ktpa design capacity plant, including associated auxiliary costs,
with infrastructure being situated near portal entrance on the north side of the deposit;
• Estimated total CAPEX of US$110 million;
• US$25 per tonne indicative OPEX processing cost at steady state conditions;
• US$36 per tonne indicative OPEX mining cost utilising mechanised cut and fill; and
• 15-year production plan, with significant potential for extension.
Basis for announcing economics
The factors that lead the Company to believe that it has a reasonable basis for announcing a production target and forecast
financial information are detailed in the Scoping Study and can be summarised as follows:
Three conceptual underground mining development and production scenarios were considered and developed throughout
the Scoping Study, resulting in the identification of a preferred scenario, highlights from which are set out below:
• decline ramp access to the north of the deposit, targeting mine production within the higher-grade core towards the
centre of the planned mining blocks;
• entry to mine via a principal decline reaching various levels;
• series of internal mining inclined ramps constructed to access levels;
• mechanised cut and fill (MCAF) mining method proposed;
• 4x4 metre mine standard development size;
• a ventilation raise would be drilled (raise-bored) to provide both adequate ambient conditions underground and a
second, emergency means of access/egress into the mine;
• ore transported to a flotation process plant by conveyor or haul truck from the mine and crushed to a suitable product
• milled ore floated by standard flotation technology to provide lead and zinc concentrate, with silver probably reporting
to the lead concentrate for sale as a combined product; and
• 4% Zn Eq cut-off used with potential for mine life extension.
