Drill Programme Update

European Metals Holdings Limited ("European Metals" or "the Company") (ASX and AIM: EMH) is pleased to announce analytical results for the confirmation drillhole CIW-11 at the Cinovec Lithium-Tin-Tungsten Project ("the project" or "Cinovec"). 

Key Points:

·     Drillhole CIW-11 returned two main mineralized intercepts of 89.95m averaging 0.61% Li2O and 109.4m averaging 0.38% Li2O.

·    The first intercept includes a high-grade interval of 63.85m @0.76% Li2O, which hosts an internal very high grade interval of 12m @1.04 %Li2O. In addition, two sections of this lithium interval contain significant tin and tungsten mineralization: 2.85m averaging 0.27% tin and 0.053% tungsten; and 6m averaging 0.18% tin and 0.009% tungsten. This yields the best Li intercept recorded by the Company to date.

·     Drilling continues in the main section of the deposit, targeting near-surface mineralization on the flanks of the historic underground mine. Altogether, five drillholes (1,644m) have been completed this year, with three underway.

European Metals CEO Keith Coughlan said "We are very pleased with the exceptional results for the latest drillhole. This is the first hole drilled in the main part of the deposit where the lithium mineralization zones are generally at shallower depths. The just obtained results are our best lithium results to date in terms of grade and continuity.  The drill programme will continue in the shallowest parts of the main deposit, along the flanks of the historic mine, where in some areas the mineralization outcrops". 

Drill Programme

The CIW-11 drillhole is located on the southern edge of the Cinovec Main sector of the deposit, in an area of relative sparsity of historic drill data and lithium analyses.

The current drill programme at Cinovec Main has been planned to confirm and delineate near surface lithium and tin mineralisation that would provide initial feed to the mill. Other goals are the conversion of resources from the Inferred to Indicated category, and delivery of material for metallurgical testing.  So far, five diamond core holes have been completed, and three are underway.  Visual inspection and logging indicates that the geology in these holes is as expected. Drill details are listed in Table 1 below.

After geological logging, drill core is cut in half with a diamond saw.  Quarter core samples are selected (honouring geological boundaries) and dispatched to ALS (Romania) for preparation and assay; the 3/4 of the core is returned to the core box and stored securely on site.  Samples are being prepared and analysed by ALS using ICP and XRF techniques following standard industry practice for lithium and tin deposits.  Strict QAQC protocols are observed, including the insertion of a Li standard in random fashion for every 10 core samples.

Mineralized Intercepts and Lithology in CIW-11

The CIW-11 drill hole is collared in rhyolite in the western area of the Cinovec cupola. The drillhole is located in the southern part of the Cinovec Main section, near the arbitrary boundary between the Cinovec Main and Cinovec South Sections.  Geologically, the drillhole resembles the geology and mineralization style of the drillholes at Cinovec South, and it yields the best Li intercept recorded by the Company to date.  The main characteristics are the presence of two massive greisen/greisenized zones in granite just below its contact with the overlying rhyolite. Based in initial observations of core from the most recently drilled holes, the near-surface or outcropping mineralization in the northern part of Cinovec Main appears of somewhat different style, with numerous but comparatively narrow greisen cored by quartz veins. 

In CIW-11, the high grade Li-mineralized greisen and strongly greisenized granite starts immediately bellow the rhyolite/granite contact at a depth of 181.15m. The mineralized intercepts in this drillhole are the best the Company has drilled to date in terms of grade, with intercepts of i.e., 63.85m@0.76%Li₂O (including 12m @1.04% Li₂O) and containing locally economic grade tin.  The best individual 1m sample reached grade of 2.13%Li₂O.

The second mineralized interval of 109.4m@0.38% Li₂O starts in 335m and thought the final depth of the hole reached 444.4m.

According to the geological and block model the greisen bodies (and the mineralized zones) dip to the southwest, although this fact could not be fully confirmed by core angles observations in the core.  The CIW-11 drillhole was angled 12 degrees toward the NE and the reported intercepts appear close to true thicknesses.

PROJECT OVERVIEW

Cinovec Lithium/Tin Project

European Metals owns 100% of the Cinovec lithium-tin deposit in the Czech Republic. Cinovec is an historic mine incorporating a significant undeveloped lithium-tin resource with by-product potential including tungsten, rubidium, scandium, niobium and tantalum and potash. Cinovec hosts a globally significant hard rock lithium deposit with a total Indicated Mineral Resource of 49.1Mt @ 0.43% Li2O and an Inferred Mineral Resource of 482Mt @ 0.43% Li₂O containing a combined 5.7 million tonnes Lithium Carbonate Equivalent.

This makes Cinovec the largest lithium deposit in Europe and the fourth largest non-brine deposit in the world.

Within this resource lies one of the largest undeveloped tin deposits in the world, with total Indicated Mineral Resource of 15.7Mt @ 0.26% Sn and an Inferred Mineral Resources of 59.7 Mt grading 0.21% Sn for a combined total of 178kt of contained tin. The Mineral Resource Estimates have been previously released on 18 May 2016. The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.

A Scoping Study conducted by specialist independent consultants indicates the deposit could be amenable to bulk underground mining. Metallurgical test work has produced both battery grade lithium carbonate and high-grade tin concentrate at excellent recoveries with the Scoping Study. Cinovec is centrally located for European end-users and is well serviced by infrastructure, with a sealed road adjacent to the deposit, rail lines located 5 km north and 8 km south of the deposit and an active 22 kV transmission line running to the historic mine. As the deposit lies in an active mining region, it has strong community support.

LITHIUM CLASSIFICATION AND CONVERSION FACTORS

Lithium grades are normally presented in percentages or parts per million (ppm). Grades of deposits are also expressed as lithium compounds in percentages, for example as a percent lithium oxide (Li₂O) content or percent lithium carbonate (Li₂CO₃) content.

Lithium carbonate equivalent ("LCE") is the industry standard terminology for, and is equivalent to, Li₂CO₃. Use of LCE is to provide data comparable with industry reports and is the total equivalent amount of lithium carbonate, assuming the lithium content in the deposit is converted to lithium carbonate, using the conversion rates in the table included below to get an equivalent Li₂CO₃ value in percent. Use of LCE assumes 100% recovery and no process losses in the extraction of Li₂CO₃ from the deposit.

Lithium resources and reserves are usually presented in tonnes of LCE or Li.

To convert the Li Inferred Mineral Resource of 532Mt @ 0.20% Li grade (as per the Competent Persons Report dated May 2016) to Li₂O, the reported Li grade of 0.20% is multiplied by the standard conversion factor of 2.153 which results in an equivalent Li₂O grade of 0.43%.

The standard conversion factors are set out in the table below:

Table: Conversion Factors for Lithium Compounds and Minerals

Convert from		Convert to Li	Convert to Li2O	Convert to Li2CO3
Lithium	Li	1.000	2.153	5.323
Lithium Oxide	Li2O	0.464	1.000	2.473
Lithium Carbonate	Li2CO3	0.188	0.404	1.000

TECHNICAL GLOSSARY

The following is a summary of technical terms:

"ball and rod indices"	Indicies that provide an assessment of the energy required to grind one tonne of material in a ball or rod mill
"carbonate"	refers to a carbonate mineral such as calcite, CaCO3
"comminution"	The crushing and/or grinding of material to a smaller scale
"cut-off grade"	lowest grade of mineralised material considered economic, used in the calculation of Mineral Resources
"deposit"	coherent geological body such as a mineralised body
"exploration"	method by which ore deposits are evaluated
"flotation"	selectively separating hydrophobic materials from hydrophilic materials to upgrade the concentration of valuable minerals
"g/t"	gram per metric tonne
"grade"	relative quantity or the percentage of ore mineral or metal content in an ore body
"heavy liquid separation"	is based on the fact that different minerals have different densities. Thus, if a mixture of minerals with different densities can be placed in a liquid with an intermediate density, the grains with densities less than that of the liquid will float and grains with densities greater than the liquid will sink
"ICP"	Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part in 1015 (part per quadrillion, ppq) on non-interfered low-background isotopes. This is achieved by ionizing the sample with inductively coupled plasma and then using a mass spectrometer to separate and quantify those ions.
"Indicated" or "Indicated Mineral Resource"	as defined in the JORC and SAMREC Codes, is that part of a Mineral Resource which has been sampled by drill holes, underground openings or other sampling procedures at locations that are too widely spaced to ensure continuity but close enough to give a reasonable indication of continuity and where geoscientific data are known with a reasonable degree of reliability. An Indicated Mineral Resource will be based on more data and therefore will be more reliable than an Inferred Mineral Resource estimate
"Inferred" or "Inferred Mineral Resource"	as defined in the JORC and SAMREC Codes, is that part of a Mineral Resource for which the tonnage and grade and mineral content can be estimated with a low level of confidence. It is inferred from the geological evidence and has assumed but not verified geological and/or grade continuity. It is based on information gathered through the appropriate techniques from locations such as outcrops, trenches, pits, working and drill holes which may be limited or of uncertain quality and reliability
"JORC Code"	Joint Ore Reserve Committee Code; the Committee is convened under the auspices of the Australasian Institute of Mining and Metallurgy
"kt"	thousand tonnes
"LCE"	the total equivalent amount of lithium carbonate (see explanation above entitled Explanation of Lithium Classification and Conversion Factors)
"lithium"	a soft, silvery-white metallic element of the alkali group, the lightest of all metals
"lithium carbonate"	the lithium salt of carbonate with the formula Li2CO3
"magnetic separation"	is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force
"metallurgical"	describing the science concerned with the production, purification and properties of metals and their applications
"Mineral Resource"	a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such a form that there are reasonable prospects for the eventual economic extraction; the location, quantity, grade geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge; mineral resources are sub-divided into Inferred, Indicated and Measured categories
"mineralisation"	process of formation and concentration of elements and their chemical compounds within a mass or body of rock
"Mt"	million tonnes
"optical microscopy"	the determination of minerals by observation through an optical microscope
"ppm"	parts per million
"recovery"	proportion of valuable material obtained in the processing of an ore, stated as a percentage of the material recovered compared with the total material present
"resources"	Measured: a mineral resource intersected and tested by drill holes, underground openings or other sampling procedures at locations which are spaced closely enough to confirm continuity and where geoscientific data are reliably known; a measured mineral resource estimate will be based on a substantial amount of reliable data, interpretation and evaluation which allows a clear determination to be made of shapes, sizes, densities and grades. Indicated: a mineral resource sampled by drill holes, underground openings or other sampling procedures at locations too widely spaced to ensure continuity but close enough to give a reasonable indication of continuity and where geoscientific data are known with a reasonable degree of reliability; an indicated resource will be based on more data, and therefore will be more reliable than an inferred resource estimate. Inferred: a mineral resource inferred from geoscientific evidence, underground openings or other sampling procedures where the lack of data is such that continuity cannot be predicted with confidence and where geoscientific data may not be known with a reasonable level of reliability
"SAGability"	testing material to investigate its performance in a semi-autonomous grinding mill
"spiral concentration"	a process that utilises the differential density of materials to concentrate valuable minerals
"stope"	underground excavation within the orebody where the main production takes place
"t"	a metric tonne
"tin"	A tetragonal mineral, rare; soft; malleable: bluish white, found chiefly in cassiterite, SnO2

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
Sampling techniques	·    Nature and quality of sampling (eg 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. ·    Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. ·    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 (eg '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 (eg submarine nodules) may warrant disclosure of detailed information.	·      As previously, the Company is conducting its core drilling programme and collecting samples from core splits in line with JORC Code 2012 Edition guidelines.  Sample intervals honour geological or visible mineralisation boundaries.  ·      Between 1952 and 1989, the Cinovec deposit was sampled in two ways: in drill core and underground channel samples. ·      Channel samples, from drift ribs and faces, were collected during detailed exploration between 1952 and 1989 by Geoindustria n.p. and Rudne Doly n.p., both Czechoslovak State companies. Sample length was 1 m, channel 10x5cm, sample mass about 15kg. Up to 1966, samples were collected using hammer and chisel; from 1966 a small drill (Holman Hammer) was used. 14179 samples were collected and transported to a crushing facility. ·      Core and channel samples were crushed in two steps: to -5mm, then to -0.5mm. 100g splits were obtained and pulverized to -0.045mm for analysis.
Drilling techniques	·    Drill type (eg 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).	·      Current programme is conventional and wireline core drilling of the deposit with percussion precollars. ·      The current core size is HQ3 (62mm diameter) in upper parts of holes; in deeper sections the core size is reduced to NQ3 (44mm diameter). Core recovery is high (average exceeds 95%). ·      Historically only core drilling was employed, either from surface or from underground.  ·      Surface drilling: 80 holes, total 30,340 meters; vertical and inclined, maximum depth 1596m (structural hole). Core diameters from 220mm near surface to 110 mm at depth. Average core recovery 89.3%. ·      Underground drilling: 766 holes for 53,126m; horizontal and inclined. Core diameter 46mm; drilled by Craelius XC42 or DIAMEC drills.
Drill sample recovery	·    Method of recording and assessing core and chip sample recoveries and results assessed. ·    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.	·      Core recovery for historical surface drill holes was recorded on drill logs and entered into the database. ·      No correlation between grade and core recovery was established.
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. ·    Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. ·    The total length and percentage of the relevant intersections logged.	·      The core descriptions are recorded into paper logging forms by hand and later entered into an Excel database. ·      The historic core was logged in detail in a facility 6 km from the mine site.  The following features were logged and recorded in paper logs: lithology, alteration (including intensity divided into weak, medium and strong/pervasive), and occurrence of potentially economic minerals expressed in %, macroscopic description of congruous intervals and structures and core recovery.
Sub-sampling techniques and sample preparation	·    If core, whether cut or sawn and whether quarter, half or all core taken. ·    If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. ·    For all sample types, the nature, quality and appropriateness of the sample preparation technique. ·    Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. ·    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. ·    Whether sample sizes are appropriate to the grain size of the material being sampled.	·      Core is washed, photographed, geologically logged, sample intervals determined and marked then the core is cut in half. One half is delivered to ALS Global for assaying after duplicates, blanks and standards are inserted in the sample stream. The remaining drill core is stored on site for reference. ·      Sample preparation is carried out by ALS Global in Romania, using industry standard techniques appropriate for the style of mineralisation represented at Cinovec. ·      Historically, core was either split or consumed entirely for analyses. ·      Samples are considered to be representative. ·      Sample size and grains size are deemed appropriate for the analytical techniques used.
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. ·    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. ·    Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	·      Core samples are assayed by ALS Global. The most appropriate analytical methods were determined by results of tests using various analytical techniques. ·      The following analytical methods are used: ME-MS81 (lithium borate fusion or 4 acid digest, ICP-MS finish) for a suite of elements including Sn and W and ME-4ACD81 (4 acid digest, ICP-AES finish) additional elements including lithium. Samples with over 1% tin are analysed by XRF. ·      Standards, blanks and duplicates are inserted into the sample stream.  In 2014 initial tin standard results indicated possible downgrading bias; the laboratory repeated the analysis with satisfactory results.  ·      Historically, tin content was measured by XRF and using wet chemical methods. W and Li were analysed by spectral methods. ·      Analytical QA was internal and external.  The former subjected 5% of the sample to repeat analysis in the same facility.  10% of samples were analysed in another laboratory, also located in Czechoslovakia. The QA/QC procedures were set to the State norms and are considered adequate. It is unknown whether external standards or sample duplicates were used. ·      Overall accuracy of sampling and assaying was proved later by test mining and reconciliation of mined and analysed grades.
Verification of sampling and assaying	·    The verification of significant intersections by either independent or alternative company personnel. ·    The use of twinned holes. ·    Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. ·    Discuss any adjustment to assay data.	·      During the 2014 drill campaign the Company indirectly verified grades of tin and lithium by comparing the length and grade of mineral intercepts with the current block model.
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. ·    Specification of the grid system used. ·    Quality and adequacy of topographic control.	·      The drill collar locations are surveyed by a registered surveyor. ·      Down hole surveys are carried out by a contractor. ·      Historically, drill hole collars were surveyed with a great degree of precision by the mine survey crew. ·      Hole locations are recorded in the local S-JTSK Krovak grid. ·      Topographic control is excellent.
Data spacing and distribution	·    Data spacing for reporting of 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. ·    Whether sample compositing has been applied.	·      Historical data density is very high.  ·      Spacing is sufficient to establish Indicated and Inferred Mineral Resources (see notes on classification below). The Mineral Resource was initially estimated using MICROMINE software in Perth, 2012 and updated in 2015. ·      Areas with lower coverage of Li% assays have been identified as exploration targets. ·      Sample compositing has not been applied.
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. ·    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.	·      Drill hole azimuth and dip is planned to intercept the mineralized zones at near-true thickness.  As the mineralized zones dip shallowly to the south, drill holes are vertical or near vertical and directed to the north. ·      The Company has not directly collected any samples underground because the workings are inaccessible at this time.  ·      Based on historic reports, level plan maps, sections and core logs, the samples were collected in an unbiased fashion, systematically on two underground levels from drift ribs and faces, as well as from underground holes drilled perpendicular to the drift directions.  The sample density is adequate for the style of deposit. ·      Multiple samples were taken and analysed by the Company from the historic tailing repository. Only lithium was analysed (Sn and W too low).  The results matched the historic grades.
Sample security	·    The measures taken to ensure sample security.	·      As in the 2014 programme, only the Company's employees and contractors handle drill core and conduct sampling. The core is collected from the drill rig each day and transported in a company vehicle to the secure Company premises where it is photographed, logged and cut.  Company geologists supervise the process and log/sample the core.   The samples are transported by Company personnel in a Company vehicle to the ALS Global laboratory pick-up station. The remaining core is stored under lock and key. ·      Historically, sample security was ensured by State norms applied to exploration.  The State norms were similar to currently accepted best practice and JORC Code guidelines for sample security.
Audits or reviews	·    The results of any audits or reviews of sampling techniques and data.	·      Review of sampling techniques possible from written records. No flaws found.

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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	·      Cinovec exploration rights held under two licenses Cinovec and Cinovec 2.  Former expires 30/7/2019, the latter 31/12/2020. ·      100% owned, no royalties, native interests or environmental concerns. ·      There are no known impediments to obtaining an Exploitation Permit for the defined resource.
Exploration done by other parties	·    Acknowledgment and appraisal of exploration by other parties.	·      There has been no acknowledgment or appraisal of exploration by other parties.
Geology	·    Deposit type, geological setting and style of mineralisation.	·      Cinovec is a granite-hosted tin-tungsten-lithium deposit. ·      Late Variscan age, alkalic rift-related granite. ·      Tin and tungsten occur in oxide minerals (cassiterite and wolframite). Lithium occurs in zinnwaldite, a Li-rich muscovite ·      Mineralisation in a small granite cupola.  Vein and greisen type. Alteration is greisenisation, silicification.
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 down hole 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.	·      Reported previously.
Data aggregation methods	·    In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. ·    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. ·    The assumptions used for any reporting of metal equivalent values should be clearly stated.	·      Reporting of exploration results has not and will not include aggregate intercepts. ·      Metal equivalent not used in reporting. ·      No grade truncations applied.
Relationship between mineralisation widths and intercept lengths	·    These relationships are particularly important in the reporting of Exploration Results. ·    If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. ·    If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').	·      Intercept widths are approximate true widths, unless noted. ·      The mineralization is mostly of disseminated nature and relatively homogeneous; the orientation of samples is of limited impact.  ·      For higher grade veins care was taken to drill at angles ensuring closeness of intercept length and true widths ·      The block model accounts for variations between apparent and true dip.
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.	·      Appropriate maps and sections have been generated by the Company, and independent consultants. Available in customary vector and raster outputs, and partially in consultant's reports.
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.	·      Balanced reporting in historic reports guaranteed by norms and standards, verified in 1997, and 2012 by independent consultants. ·      The historic reporting was completed by several State institutions and cross validated.
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.	·      Data available: bulk density for all representative rock and ore types; petrographic and mineralogical studies, hydrological information, hardness, moisture content, fragmentation etc.
Further work	·    The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). ·    Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	·      Grade verification sampling from underground or drilling from surface (in progress).  Historically-reported grades require modern validation in order to improve the resource classification. ·      The number and location of sample sites have been determined from a 3D wireframe model and geostatistical considerations reflecting grade continuity.  ·      The geologic model will be used to determine if infill drilling is required. ·      The deposit is open down-dip on the southern extension, and locally poorly constrained at its western and eastern extensions, where limited additional drilling might be required.  ·      No large scale drilling campaigns are required.
