Pb, Zn, Ag & Cu Drilling Results and Updated Resource Estimate to be Commissioned - Toral Project, Spain

Europa Metals, the European focused lead-zinc and silver developer, is pleased to announce further assay results including high-grade intersections of lead, zinc and silver, in addition to an interval of nearly 1% copper, at the Company's 100% owned Toral Pb, Zn & Ag project ("Toral" or the "Toral Project").

This latest 2021 infill drilling campaign was designed to improve the Company's understanding of the deposit and assess the potential for increasing future production in the early years of the planned mine life, thereby enhancing the project's pay-back period and profitability. Following the high-grade results consistently generated during the last eight months and the retrieval of significant amounts of material for metallurgical ore sorting work the Company has now concluded this drilling phase. 

Europa Metals is now assessing the impact of these final assay results on its existing global and indicated resource and commissioning a new independent updated resource estimate from Addison Mining Services Limited ("AMS"). A further, independent, metallurgical and concentrate work programme will then contribute to the Toral project's production profile/design within the early years of the project with a view to enhancing the project's pay-back period and profitability.

The wide diameter, PQ, diamond drilling programme was conducted by Sondeos y Perforaciones Industriales de Bierzo SA ("SPI Drilling").

Commenting today, Laurence Read, CEO of Europa Metals said:

"The results from this latest round of drilling in terms of grades and widths of lead, zinc and silver are in our view exceptional and exceed our initial expectations for the upper zone of the Toral project, an area that we have always viewed as being the 'path' towards the lower, high-grade production zones.

"The 2021 drilling campaign has been excellent and I would like to thank our team on the ground for their hard work in consistently delivering within the highly challenging environment of COVID-19.

"The Company has decided to conclude drilling and is assessing the potentially positive impact these intersections could have on the existing resource model and the potential future economics for the Toral project. Even with a high-grade project with a robust EBITDA margin at the three-year trailing metals prices in the last independent economic study, we believe that further enhancements can be achieved from optimising the mining route and further determining processing systems such as ore sorting, or separate ore sorting processes for different ore types.

"We are also considering the recent copper results of nearly one per cent. and potential options for technical partnering to assess what is happening within the system regarding this metal. Whilst Toral is to date primarily a lead, zinc and silver project, the presence of copper in the system encourages our belief that potential sources may be present below the current 1,000 metre cut off.

"Such work continues to de-risk the Toral project as a viable low cost, high margin future production source with the potential to significantly expand both the current mine life and the metals concentrate profile."

Commenting today, Myles Campion, Executive Chairman of Europa Metals said:

"This year's drilling campaign into the upper siliceous zone of Toral has indeed exceeded expectations. We have obtained a significant amount of bulk sample material from this zone, through the utilisation of PQ size drilling, that will enable us to complete an ore sorting and metallurgical testwork programme in conjunction with WAI.

"Throughout the campaign the Europa Metals team has, in house, been updating our resource model as further information has become available. This will enable us to move quickly to commission an independent update to the existing resource estimate. We look forward to releasing such update to the market in due course."

Drill Campaign's Objectives

 

The drilling campaign was designed to infill known gaps in the resource drilling pattern, around the current known Indicated resource at Toral between the 100 - 800 metre horizon. The holes were also designed to retrieve a bulk sample for use in further metallurgical testwork in order to confirm the suitability of the siliceous ore type, found in the upper levels of the Toral deposit, for X-Ray Transmission ore sorting. Geotechnical logging was also routinely carried out for each hole to aggregate further data for our geotechnical database in order to facilitate further design studies.

 

Drill holes were located above the current Indicated resource area, in a zone containing a siliceous style of mineralisation (the lower, high-grade zones of Toral hosting a predominantly carbonate style of mineralisation) with the drilling being conducted using the biggest core size possible (PQ) to enable the retrieval of a new bulk sample for further metallurgical test work.

 

Drilling Results

Hole TOD-029 identified significant widths of the siliceous style of mineralisation present in the upper parts of Toral. The total length of the intersection was 20.45m @ 2.68% ZnEq(PbAg) which included 3.8m @ 8.87% ZnEq(PbAg).

The team elected to drill four "daughter" holes or wedges from the parent TOD-029 hole in order to acquire more sample to be utilised in the PFS ore sorting metallurgical testwork programme.

The results included:

·    Hole TOD-028 intersected 2.4m @ 10.58% ZnEq(PbAg)

·    Hole TOD-030 intersected 2m @ 1.11% ZnEq(PbAg)

·    Hole TOD-031 intersected 1.05m @ 4.39% ZnEq(PbAg)

·    Hole TOD-032 intersected 2.7m @ 11.14% ZnEq(PbAg)

·    Hole TOD-033 intersected 1.1m @ 4.24% ZnEq(PbAg)

·    Hole TOD-034 intersected 14.85m @ 8.36% ZnEq(PbAg)

·    Hole TOD-035 no significant intersection

Such heterogenous results were expected across this upper part of Toral and by utilising the samples collated into a bulk sample, Europa Metals will be able to further determine and refine the economic viability of ore sorting as a component in the planned processing route.

Significant ZnEq intercepts were generated using a total length mineralisation. Zn equivalent calculations were based on 3-year trailing average price statistics obtained from the London Metal Exchange. ZnEq (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*0.904 + Ag*0.019). No top cutting was applied to Zn, Pb, Ag or Cu grades. Interval widths reported are the downhole length and are unlikely to reflect true widths owing to the mineralisation style at the project. True thickness is approximately 70% of the drill thickness.

* - ZnEq (Pb)% is the calculated Zn equivalent incorporating lead credits; (ZnEq (Pb)% = Zn + Pb*0.926). ZnEq (PbAg)% is the calculated Zn equivalent incorporating silver credits as well as lead; (ZnEq (PbAg)% = Zn + Pb*0.926 + Ag*0.019). 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$2,680/t, Pb price of US$2,100/t and Ag price of US$16.2/oz.

 

Notes:

1.    No mineral reserve calculations have been undertaken. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

2.    Numbers are rounded to reflect the fact that an Estimate of Resources is being 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$2,680/t, Pb price of US$2,100/t and Ag price of US$16.2/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.    ZnEq (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 (ZnEq (PbAg)% = Zn + Pb*0.926 + Ag*0.019).

5.    ZnEq is the calculated Zn equivalent using lead credits and does not include silver credits (ZnEq = Zn + Pb*0.926).

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 21 January 2020. The block model used uniform cell size of 25x10x25m 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 Kriging.

7.    Following statistical analysis and assessment of the updated assay composite database top cuts of 125g/t Ag were applied to the data.  No top cuts were applied for Zn or Pb.

8.    The Indicated and Inferred mineral resource category for the Toral zinc-lead-silver project set out in Table 1 (at cut-off grades >4% Zn Equivalent) comply with the resource definitions as described in the Australasian Code for 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.
