Beowulf (AIM: BEM; Aktietorget: BEO), the mineral exploration and development company focused on the Kallak magnetite iron ore project and the Åtvidaberg polymetallic exploration licence in Sweden, and its graphite portfolio in Finland, is pleased to announce further results from its recently completed eight-hole diamond drill programme at its 100 per cent owned Aitolampi graphite prospect.

Highlights:

  • Drilling confirms that electromagnetic (“EM”) anomalies identified at Aitolampi are associated with wide zones of graphite mineralisation, with a mineralised strike length of at least 350m along the main conductive zone drill-tested, dipping between 40 and 50 degrees to the southwest.  The main EM zone extends for 700m.
  • Drill hole AITDD17006 intercepted 202.98m at 3.09 per cent Total Graphite Carbon (“TGC”) from 19.2m depth (this includes some barren zones with no assays and calculated as zero per cent TGC), and higher-grade zones of 18.95m at 6.33 per cent TGC, and 14m at 6.26 per cent TGC.  
  • Drill hole AITDD17001 intercepted 141.86m at 3.72 per cent TGC from 19.67m depth, including a higher-grade zone of 39.48m at 5.02 per cent TGC.
  • Drill hole AITDD17008 intercepted 60.29m at 4.01 per cent TGC from 8.71m depth, including 12m at 5.79 per cent TGC.
  • Drill hole AITDD17005 intercepted 41.1m at 4.39 per cent TGC from start of hole, including 28.4m at 5.1 per cent TGC and 4m at 7.71 per cent TGC.

It should be noted that the mineralisation intercepts are the down-hole widths and are not the true width of mineralisation.  All samples were prepared and analysed by ALS Finland Oy’s laboratory in Outokumpu.

Composite samples for metallurgical testwork have been dispatched to SGS Mineral Services in Canada, including an average grade composite for the main conductive zone, a higher-grade composite for the main conductive zone/near-surface mineralisation, and a higher-grade composite for the parallel conductive zones.  Results are expected in the summer.

Plans and cross sections showing these results can be found on the Company’s website at www.beowulfmining.com.

Kurt Budge, Chief Executive Officer of Beowulf, commented:

“We are pleased to provide a further update on our recent drilling programme, having now put some scale to the mineralisation at Aitolampi, along strike and sub-surface.  We have drilled half the length of the 700m EM conductive zone and confirmed mineralisation. We look forward to the results of the metallurgical testwork on three composite samples, which will add to the current picture, and demonstrate what we can produce from Aitolampi, in terms of concentrate grades and flake size distribution.  

“On 8 May, the Company’s exploration team began a two months’ field programme at Haapamäki, Pitkäjärvi and Aitolampi, which includes further Slingram EM surveys and geological mapping, with the objective of defining new drill targets.  

“Over the summer, the team will be carrying out fieldwork on the Company’s Kolari and Viistola graphite projects, which will help us improve our understanding of both. Also, the fieldwork programmes will enable us to rank all our prospects and best allocate investment capital. 

“We look forward to keeping shareholders updated on our progress.”

Aitolampi - Background

Aitolampi is in eastern Finland, approximately 40 kilometres (“km”) southwest of the well-established mining town of Outokumpu.  Infrastructure in the area is excellent, with road access and available high voltage power.

The area has extensive EM conductive zones (anomalies) that were first defined by an airborne survey carried out by the Geological Survey of Finland (“GTK”). In 2016, the Company carried out its own in-house Slingram EM surveys to add further definition to the GTK survey and geological mapping. The EM anomalous trend from Pitkӓjӓrvi to Aitolampi extends more than 16km in length and up to 0.6km in width.

Aitolampi - Drilling

The objective of the drilling programme was to assess the potential for sub-surface graphite mineralisation (extent, width, depth, and continuity) along a major EM conductive zone, and to test two parallel conductive zones to the southwest of the main zone.

Drill results confirm that the EM zones tested are associated with wide zones of graphite mineralisation continuous along strike and down dip.  Geological interpretation of the drill data shows that the graphite mineralised zones strike parallel to and are coincidental with the EM conductors (northwest-southeast).  The zones dip between 40 to 50 degrees to the southwest and can be very broad, attaining a down the hole thickness of up of up to 140m, as intersected in drill hole AITDD17001 on section 6935566N on the main EM anomaly. Drilling has confirmed mineralisation for 350m along strike in that part of the EM conductive zone, with the identified EM anomaly extending for 700m in total.

Higher-grade graphite zones are evident within the broader mineralised zones as seen in drill hole AITDD17006 on section 6935371N, designed to test two parallel conductors southwest of the main conductive zone. Intercepts include down the hole widths of 18.95m at 6.33 per cent TGC from 20.6m, and 14.0m at 6.26 per cent TGC from 102m, within a broader zone of 45.80m at 4.71 per cent TGC and 50.6m at 4.4 per cent TGC. These conductive zones extend along strike for 200m and 300m respectively.

Viistola

Viistola is in eastern Finland approximately 30km southeast of the town of Joensuu.  In February 2016, the Company applied for an exploration permit 0.74 square kilometres (“km²”), which includes an EM conductor associated with graphite schist. The graphite is hosted in a massive to brecciated graphitic schist associated with gabbro, quartzite, dolomite and phyllite country rocks.

Based on historical diamond drilling, rock chip drilling, trenching and ground geophysics, a potential target at Hyypiä, a prospect which forms part of Viistola, has been identified.  The Company’s exploration team plans to be on site in Q3 2017. 

Kolari

Kolari is in northwest Finland approximately 50km and 100km east of Talga Resources' (ASX:TLG) Vittangi project and Jalkunen graphite projects respectively, both of which are situated in Sweden.  The Company has a 100 per cent owned claim reservation over an area of 96.97km².  A desktop study of the area has been completed and shows extensive areas of graphitic schist. The Company’s exploration team plans to be on site in Q3 2017.

JORC Code, 2012 Edition – Table 1

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.
  • Diamond drill core was sampled based on visually observed graphite mineralization.
  • The drill core was either half-cut (drill holes AITDD17001-17005) or quarter-cut (drill holes AITDD17006-17008).
  • Sampling was carried out under the Company`s sampling protocols and QA/QC procedures as per industry best practice.
  • The drill core has been sampled on geological intervals of 1m-3m, and 2m intervals within wider mineralized intercepts where appropriate. All samples were crushed and pulverized to produce a sub-sample to be analysed for Graphitic Carbon by Leco furnace, Total Carbon by Leco furnace, and Total Sulphur by Leco furnace and infrared spectroscopy.
Drilling techniques 
  • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).
  • Diamond drilling was completed by Northdrill Oy from Finland.
  • Using WL76 equipment, with a core diameter of 61.77mm.
  • Core was orientated for all holes using Reflex ACT 3 core orientation tool.
  • Downhole surveys for all drill holes were completed by Northdrill Oy using a Deviflex instrument.

  • Core recovery was measured and recorded for every core run by the drillers. Any core loss was recorded on the core blocks by the drillers.
  • Core recovery was double-checked and measured for all drill holes by the Company`s geologists during core logging. The core length recovered was calculated as a percentage of the theoretical core length.
  • No additional measures were taken to maximize core recovery.
  • The core recovery was generally very good and a sampling bias has not been determined.
Logging

  • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
  • The total length and percentage of the relevant intersections logged.
  • All drill core was geologically logged, determining lithology, mineralogy, mineralization, texture, and structural observations.
  • Density, RQD and core recovery were measured on all drill core by the Company`s geologists.
  • All drill core was photographed in wet and dry states after logging was completed, and sample intervals had been marked on the core boxes.

  • Samples were prepared following industry best practice by ALS Finland Oy. Each sample is crushed with more than 70% passing the < 2mm, then reduced in a splitter to 250g. The 250g sample is pulverized with more than 85% passing < 75 microns. A sub-sample of pulp is taken from homogenized sample to be analysed for Graphitic Carbon by Leco furnace, Total Carbon by Leco furnace, and Total Sulphur by Leco furnace and infrared spectroscopy. Selected samples were analysed for multi-elements by Ultra Trace Level Aqua Regia Method ME-MS41.
  • Duplicate samples were completed at a rate of 1:40 to 1:60 where practicable.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria JORC Code explanation 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 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 Aitolampi mineralization is located within exploration permit Pitkäjärvi (ML2016:0040).
  • The exploration permit is 100% owned by the Company`s Finnish subsidiary. No native title interest, historical sites, national parks or nature conservation areas exist within the exploration permit.
  • The exploration permit is in good standing with the local mining authority TUKES.
Exploration done by other parties 
  • Acknowledgment and appraisal of exploration by other parties.
  • No historic exploration for graphite has been done at the Aitolampi prospect.
Geology 
  • Deposit type, geological setting and style of mineralisation.
  • The Pitkäjärvi exploration permit area belongs to the geological unit of the Karelian domain, part of the proterozoic svecokarelian supracrustal rocks. The area is in a regional open fold of considerable size, about 10km wide and 20-30km long which is cut by a regional fault zone(s) in the northeast. The fold is clearly visible on aeromagnetic and electromagnetic maps. Quartz-feldspar-biotite gneiss is the most common rock type in the area. The main mineral composition of the gneiss is quartz, feldspars (mainly plagioclase), micas (mainly biotite) ± graphite. Accessory minerals seen in thin sections are zircons, garnets, sericite, and chlorite. Graphite schist is common as layers and lenses in the quartz-feldspar-biotite gneiss. These metasediments have been metamorphosed to the upper amphibolite to granulite facies (650-700˚C, 4-5kbar).
  • The graphite mineralization at Aitolampi is comprised of a number of graphite lenses which generally extend for several hundred metres along strike and dips 40-50⁰ to southwest. Based on the completed drill program the known graphite/sulphide bearing lenses consists of 40-140m wide continuous units of predominately fine to medium size graphite flakes containing approximately 4% total graphitic carbon. The hanging-wall and footwall is comprised of quartz-feldspar-biotite rich gneisses with common garnet porphyroblasts. The graphitic lenses are commonly intruded by pegmatite veins which vary from tens of centimetres to tens of metres in thickness.
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: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.
    • 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.
  • A tabulation of the drill hole information and mineralized down hole intercepts, length, and depth, can be found on the Company`s website.
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.
  • No cut-off grade has been applied in this report.
  • No metal equivalents have been used in this report.
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’).
  • Only the down hole lengths are reported.
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, sections and tabulations can be found on the Company`s website.
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.
  • Both low and high grades, and the widths of the intercepts are reported.
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.   
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.
  • Metallurgical testwork on representative core samples will be completed at SGS Mineral Services in Canada.
  • Further geological mapping, EM slingram measurements, followed by geological and geophysical interpretation will be completed during the coming months.
