Continued High-grade Mineralisation Intercepted Northwest of Rupice

 

VARES PROJECT EXPLORATION HIGHLIGHTS

 

Exploration drilling northwest of the Rupice Mineral Resource continues to intercept additional high-grade mineralisation.

Diamond drillhole BR-12-21, 145 metres northwest of the existing Rupice Mineral Resource, intercepted:

·      24.7 metres at 514g/t AgEq (181g/t Ag, 9.0% Zn, 4.6% Pb, 0.9g/t Au, 0.3% Cu, 67% BaSO4, 0.1% Sb) from 295.1 metres

BR-16-21 confirmed continuity within the zone of extension intercepting:

·      7.1 metres at 1123g/t AgEq (662g/t Ag, 11.3% Zn, 7.6% Pb, 3.4g/t Au, 0.7% Cu, 62% BaSO4, 0.3% Sb) from 350 metres

BR-19-21 also confirmed continuity with:

·      15.8 metres at 508g/t AgEq (280g/t Ag, 4.8% Zn, 4.0% Pb, 1.9g/t Au, 0.3% Cu, 74% BaSO4, 0.1% Sb) from 346.2 metres

Geotechnical Drilling

A further 123 geotechnical drill holes have been completed since the 2021 DFS, underpinning the detailed engineering design and delivery of the Vares Silver Project. G

Paul Cronin, Adriatic's Managing Director and CEO, commented: "The extensional drilling completed to date demonstrates that excellent exploration potential still remains at Rupice. While extending the known mineralised zone by 145 metres, BR-12-21 also shows a thickening of the massive sulphide mineralisation to the north. We plan for drilling to continue through winter, alongside the civil earth works underway for the Rupice Underground Mine surface infrastructure.

Given the thickness and continuity demonstrated at Rupice Northwest, the recent drilling results, and ongoing exploration activities are expected to extend the current 10 year mine plan at Rupice, as well as offering potential optionality to alter the current mine plan to access the higher grade areas earlier in the mine life.

In addition, the documentation for the US$142.5 million debt component to the Project Finance package provided by Orion is progressing well and we expect to execute in the coming days, with closing remaining on track for end of February."

 

Adriatic Metals PLC (ASX:ADT, LSE:ADT1, OTCQX:ADMLF) is pleased to report on recent exploration results at the Company's flagship Vares Silver Project in Bosnia & Herzegovina.

As announced on 10 August 2021, step-out exploration drilling intersected high-grade mineralisation in drill hole BR-02-21, located 80 metres northwest of the existing Rupice Mineral Resource ("Rupice"). Subsequently, the Company has focused exploration activities on testing this potential northwest extension ("Rupice Northwest") with continued success. As shown in Figure 1, the delineated strike length of Rupice is 650 metres. Recent drilling has now encountered massive sulphide mineralisation as far as 145 metres northwest of Rupice.

The stratigraphic sequence and mineralisation style at Rupice Northwest appears to be the same as that seen at Rupice. Whether this is a continuation of the main Rupice orebody, or a structural repetition is yet to be determined. The mineralisation at Rupice Northwest is continuous along strike to the northwest, as seen from the drill hole data in holes BR-02-21, BR-12-21 and BR-19-21. However, there appears to be a sporadically mineralised, lower-grade gap between Rupice and Rupice Northwest as shown in Figure 1 and 4. Hole BR-06-21 intercepted a two metre zone of mineralisation grading 1,268g/t AgEq from 413m and approximately 20m south east of BR-02-21. This zone will be further tested with ongoing drilling.

The Company has made preparations for exploration activities around Rupice to continue throughout the forthcoming winter season. Due to the lack of infrastructure available at Rupice and restricted access due to snow, drilling through the winter in previous years was limited due to safety considerations. However, with the commencement of civil earth works on the Rupice Surface Infrastructure site and the access road construction, safe access to planned drill pads will be greatly improved allowing exploration activities to continue throughout the winter. Drilling will primarily be focused on continued step-out and definition drilling within the Rupice Northwest area to better define the mineralised strike, as well as the up-dip and down-dip extents. Mineralisation at the southern and south-eastern parts of Rupice remains open. A recently completed drill hole (BR-21-21) on the southern extent of Rupice encountered massive sulphide mineralisation, the assays for which are pending. Follow-up extensional drilling is also planned here in the New Year.

Subsequent to the release of the 2021 Vares Project Definitive Feasibility Study on 19 August 2021 ("2021 DFS"), modifications have been made to the layout of the Rupice Surface Infrastructure site and access road, which has required additional geotechnical drilling. Since the 2021 DFS, a total of 123 geotechnical drill holes have been completed across the project covering the proposed surface infrastructure and roads. This has continued to limit the number of drill rigs available for exploration drilling. However, geotechnical drilling activities are nearing completion, which will increase the drill rig availability for exploration in the New Year. In addition, poor drill hole performance at Rupice Northwest has led to a number of exploration holes being abandoned before reaching the depth of the expected mineralised horizon. The Company is currently tendering for an additional drilling contractor to assist with improving the drilling performance in this area to be mobilised in the New Year.

Notes

1.         Significant intervals are estimated using a 50g/t Ag cut off, 2m minimum interval and 5 metres consecutive internal dilution. Higher grade intervals have a 350g/t Ag cut off.

2.         AgEq & ZnEq grades are based on the following metal prices used in the DFS: $1800/oz gold, $25/oz silver, $3000/t lead, $2300/t zinc, $9500/t copper & $2300/t antimony.

3.         The following metal recoveries were derived from the DFS and cumulative recoveries of all concentrates were used: 89% silver, 91% zinc, 92% lead, 64% gold, 94% copper and 95% antimony.

4.         The following metal payabilities were derived from the DFS and cumulative payabilities of all concentrates were used: 88% silver, 75% zinc, 87% lead, 77% gold, 16% copper and 84% antimony.

5.         The silver equivalent calculation is as follows: AgEq = ((Au grade g/t /31.103 * Au recovery % * Au price $/oz) + (Ag grade g/t /31.103 * Ag recovery % * Ag price $/oz) + (Pb grade % /100 * Pb recovery % * Pb price $/t) + (Zn grade % /100 * Zn recovery % * Zn price $/t) + (Cu grade %/100 * Cu recovery % * Cu price $/t) + (Sb grade % /100 * Sb recovery % * Sb price $/t))/Ag price $/oz * 31.103

6.         The zinc equivalent calculation is as follows: ZnEq = ((Au grade g/t /31.103 * Au recovery % * Au price $/oz) + (Ag grade g/t /31.103 * Ag recovery % * Ag price $/oz) + (Pb grade % /100 * Pb recovery % * Pb price $/t) + (Zn grade % /100 * Zn recovery % * Zn price $/t) + (Cu grade %/100 * Cu recovery % * Cu price $/t) + (Sb grade % /100 * Sb recovery % * Sb price $/t))/Zn price $/t *100

7.         It is the opinion of Adriatic Metals and the Competent Person that all elements and products included in the metal equivalent formula have a reasonable potential to be recovered and sold.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

 

Criteria

JORC Code Explanation

Commentary

Sampling techniques

Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

Drill core samples were collected from half cut PQ3 and HQ3 diameter core, where the core was sawn exactly in half along a pre-defined cutting line. The half core samples, typically weighing between 4-12kg, were placed into labelled and tagged sample bags prior to dispatch to the ALS preparation facility in Bor, Serbia. Sample intervals were determined by the geologist, usually at 2m intervals within massive ore, otherwise separated on narrower intervals where geological boundaries exist.

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Sample intervals were selected by the logging geologist based on geological criteria or using a nominal maximum 2m sample length in homogenous massive sulphide ore. A minimum sample length of 0.2m is employed where necessary. Sampling is based on visually mineralised intervals, with a calibrated portable XRF device used only as a guide.

Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.

For drill hole analyses, diamond drilling was used to obtain 4 to 12kg samples, prepared at ALS Bor, Serbia (code PREP-31by). The sample pulps were sent to ALS Rosia Montana, Romania by air freight for gold analysis by 50 gram fire assay with AA finish (code FA-AA24), and multi-element analyses were conducted by ALS Loughrea, Ireland using a highly oxidising digestion with ICP-MS finish (code ME-ICP61m). Barite was assayed using lithium borate fusion prior to acid dissolution and ICP-MS analysis (code ME-ICP06).

 

 

Drilling techniques

Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

 

 

 

All drill holes were drilled using PQ3 and HQ3 diameter core with the exception of BR-06-21 which was drilled by non-coring methods (tircon) from 0-105m followed by HQ3 diameter core.

Three contractors were responsible for drilling the reported holes: GeoAVAS d.o.o (BR-04-21, BR-06-21, BR-20-21) Geops (BR-07-21, BR-10-21, BR-11-21, BR-13-21, BR-14-21, BR-16-21, BR-17-21, BR-18-21, BR-19-21) and GIM Geotehnika d.o.o (BR-03-21, BR-12-21, BR-15-21).

PQ3 and HQ3 core was held in a core barrel by a stainless steel "split" inner tube. The use of the inner tube ensured that all core maintained its orientation prior to removal into the core trays. Drill core was stored in suitable core boxes and racked inside at the Vares Processing Plant office-warehouse complex.

All drillholes were surveyed at 9m and every 30m thereafter. Significant deviation was common due to poor geotechnical conditions, particularly passing through a large fault zone associated with the Jurassic-Triassic geological boundary.

Numerous drillholes in the programme were abandoned owing to technical difficulties.

Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

All core was geotechnically logged to verify drillers blocks, record run length, recovered length, core recovery (%) and RQD. Core recovery was maximised by drilling shorter drill runs in friable zones and zones of water loss.

There is no observed relationship between sample recovery and grade, and with little to no loss of material there is considered to be little to no sample bias.

Measures taken to maximise sample recovery and ensure representative nature of the samples.

Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.

Logging

Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

Core samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Not all drill holes penetrated the massive sulphide mineralisation, but all were used to guide the geological interpretations supporting the Mineral Resource estimates.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

 

All core is photographed. Core logging is both qualitative and quantitative.

The total length and percentage of the relevant intersections logged.

100% of drill core is logged.

Sub-sampling techniques and sample preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

The diamond core was cut in half using a diamond saw. Nominally 1 in 30 samples was cut in quarters, and both halves analysed (for purposes of field duplicates).

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

Not applicable, as all samples are core.

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Collection of around 4-6kg of half core material with subsequent pulverisation of the total charge provided an appropriate and representative sample for analysis. Sample preparation was undertaken at the ALS laboratory in Bor, to industry best practice.

Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

Whole rock blanks and certified standards (~1 in 15) were introduced to the sample run to ensure laboratory QAQC. Additionally, industry best practice was adopted by ALS for laboratory sub-sampling and the avoidance of any cross contamination.

Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling.

The half core sampling is considered a reasonable representation of the in-situ material. Nominally 1 in 30 samples were cut in quarters, and both halves analyses (for purposes of field duplicates).

Whether sample sizes are appropriate to the grain size of the material being sampled.

Sample size of around 4-12kg is considered to be appropriate to reasonably represent the material being tested.

Quality of assay data and laboratory tests

The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.

Analyses were undertaken at the accredited laboratory of ALS in Bor, Serbia which has full industry certification. Multi elements were assayed by an ICP-AES technique following a four-acid digest. Gold was determined using a fire assay on a nominal 50g charge. Barite was determined from a lithium borate fusion followed by dissolution and ICP-AES analysis. Total sulphur was determined by Leco.

All techniques were appropriate for the elements being determined. Samples are considered a partial digestion when using an aqua regia digest.

For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.

There was no reliance on determination of analysis by geophysical tools.

Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.

Certified Reference Material ("CRM") appropriate for the elements being analysed were added at a rate better than 1 in 15. All results reported by ALS on the CRMs were better than 2 standard deviations (2SD), it is considered that acceptable levels of accuracy have been achieved.

Additional lab checks are regularly sent to the SGS lab in Bor, Serbia.

Verification of sampling and assaying

The verification of significant intersections by either independent or alternative company personnel.

There has been no independent logging of mineralised intervals, however, it has been logged by several company personnel and verified by senior staff.

The use of twinned holes.

None of the reported holes are twin holes.

Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

Data is stored on the Virtual Cloud and at various locations including Vares, Bosnia & Herzegovina and Cheltenham, UK. And is managed by gDat data solutions in an acQuire database, which is regularly backed-up.

Discuss any adjustment to assay data.

No adjustments were necessary.

Location of data points

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

Sampling sites were surveyed using Total Station to better than 0.05m accuracy in the local BiH coordinate system.

Specification of the grid system used.

The grid system used MGI 1901 / Balkans Zone 6.

Quality and adequacy of topographic control.

The topographic surface of the immediate area was generated from a LiDAR survey to an accuracy of approximately 0.05m. It is considered sufficiently accurate for the Company's current activities.

Data spacing and distribution

Data spacing for reporting of Exploration Results.

Drill hole spacing does not exceed 50m which is considered acceptable for reporting exploration results. 

Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.

Drill hole spacing is deemed sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource classifications applied.

Whether sample compositing has been applied.

Sample composite was not employed.

Orientation of data in relation to geological structure

Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.

Drill holes are considered to have been drilled at between 60-90° to the mineralised body.

If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

It is not considered that the drilling orientation has introduced a sampling bias, as the drilling is considered to be drilled at a high angle to the mineralised body.

Sample security

The measures taken to ensure sample security.

Chain of Custody of digital data is managed by the Company. Physical material was stored on site and, when necessary, delivered to the assay laboratory. Thereafter laboratory samples were controlled by the nominated laboratory. All sample collection was controlled by digital sample control file(s) and hard-copy ticket books.

Audits or reviews

The results of any audits or reviews of sampling techniques and data.

A Site and Laboratory (ALS and SGS, Bor) visit was made by Dr Belinda van Lente, an employee of CSA Global in January 2018. There were no material issues found for the 2017 drill campaign.

Commentary

Mineral tenement and land tenure status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

The Rupice deposit is located within the Company's 100% owned Concession, No. 04-18-21389-1/13, located 13km west of Vares in Bosnia. There are no known material issues with any third party other than normal royalties due to the State.

The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

The Concession is in good standing with the governing authority and there is no known impediment to the Concession remaining in force until 2038 (25 years), subject to meeting all necessary reporting requirements.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties.

Modern exploration commenced with the work of Energoinvest in the late 1960s. During 1968-1969 underground development of 455m of drives and cross cuts were made, and 11 surface trenches dug for a total length of 93.5mm. Between 1980 and 1989, 49 holes were drilled for an advance of 5,690.8m. Sample material from all of these programs was routinely analysed for lead, zinc, and barite, and on occasion silver and gold. The deposit was the subject of a number of reserve estimates in the 1980s. This work is documented in many reports which are certified by those geoscientists and Institutes that undertook the work.

 

The work is considered to be of a standard equal to that prevalent within today's exploration industry.

Geology

Deposit type, geological setting and style of mineralisation.

The host rocks at Rupice comprises Middle Triassic limestone, dolostone, calcareous and dolomitic marl, and a range of mostly fine-grained siliciclastic rocks including cherty mudstone, mudstone, siltstone and fine-grained sandstone. The main mineralised horizon is a brecciated dolomitic unit that dips at around 50o to the northeast and has been preferentially mineralised with base, precious and transitional metals. The Triassic sequence and has been intensely deformed both by early stage ductile shearing and late stage brittle faulting.

The Rupice polymetallic mineralisation consists of sphalerite, galena, barite and chalcopyrite with gold, silver, tetrahedrite, boulangerite and bournonite, with pyrite. The majority of the high-grade mineralisation is hosted within the brecciated dolomitic unit, which is offset and cut by northwest striking, westerly dipping syn-post mineral faulting. This faulting displaces the mineralised body up to 20 metres in places. Thickening of the central portion of the orebody occurs where these faults flexure and deform. Mineralised widths up to 65 metres true thickness are seen in the central portion of the orebody.

To date, the massive sulphide mineralisation at Rupice has a defined strike length of 650 metres, with an average true-width thickness of around 20 metres. However, recent drilling northwest of Rupice has intercepted massive sulphide 125 m along strike and mineralisation remains open.

Drill hole information

A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

o     easting and northing of the drill hole collar

o     elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

o     dip and azimuth of the hole

o     downhole length and interception depth

o     hole length.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

Drilling data for the reported drill holes is included in Tables 1-3 of Appendix 1 in this document.

 Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.

Significant intercepts were calculated by applying a lower cut-off grade of 50g/t AgEq (see below assumptions for AgEq & ZnEq calculations), 2m minimum intervale and maximum internal dilution of 5m. A top-cut was not applied. Significant intercepts were reported as weighted averages.

Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

Short lengths of high-grade results were defined as >350g/t Ag, 2m minimum interval and maximum internal dilution of 5m. Results are shown in Table 1 of the main reporting document.

The assumptions used for any reporting of metal equivalent values should be clearly stated.

Equivalent explanations are described in the body of the text.

Relationship between mineralisation widths and intercept lengths

These relationships are particularly important in the reporting of Exploration Results.

Only downhole lengths are reported, true widths are not known.

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

The majority of the high-grade mineralisation is hosted within the brecciated dolomitic unit, which is offset and cut by northwest striking, westerly dipping syn-post mineral faulting. This faulting displaces the mineralised body up to 20 metres in places. Thickening of the central portion of the orebody occurs where these faults flexure and deform. Mineralised widths up to 65 metres true thickness are seen in the central portion of the orebody.

To date, the massive sulphide mineralisation at Rupice has a defined strike length of 650 metres, with an average true-width thickness of around 20 metres. However, mineralisation at Rupice still remains open towards the north and down-dip to the south.

Recent drilling by Eastern Mining was mostly inclined at between 70o and 80 o to the southwest, perpendicular to the deposit strike, and intersected the mineralisation reasonably orthogonally.

If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. 'downhole length, true width not known').

Only downhole lengths are reported, true widths are not known.

Diagrams

Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

Relevant maps and diagrams are included in the body of the report. 

Metallurgical test work results being reported do not require maps and diagrams.

Balanced reporting

Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high-grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

All assay tables for all reported holes are included in the main reporting document.

Other substantive exploration data

Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

No substantive exploration data not already mentioned in the announcement or in this table have been used.

 

Further work

The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).

Further drilling will be undertaken for exploration along strike and down dip, the nature of which is dependent on exploration success and funding.

Further drilling will be undertaken for geotechnical and metallurgical purposes, to include locked cycle tests, bulk samples and variability testing

Additional drilling is recommended to improve geological confidence to upgrade the resource to higher confidence categories (i.e. from Inferred Mineral Resource to Indicated Mineral Resource, and from Indicated Mineral Resource to Measured Mineral Resource to aid in future Ore Reserve estimates (in future Feasibility Studies).
