Mineral resource assessment and 3D modelling of the Leviäkangas lithium pegmatite deposit, Western Finland Abstract

The Leviäkangas lithium pegmatite deposit is located in the municipality of Kaustinen in Western Finland, about 55 km southeast of the city of Kokkola. The area belongs to the Pohjanmaa Schist Belt between the Central Finland Granitoid Complex in the east and the Vasa Migmatite Complex in the west. The area under the prospect titled “Leviäkangas I”, mining register number 8390/1, covers 90 hectares. Suomen Mineraali Oy conducted the first explorations of the lithium pegmatites in Leviäkangas (previously known as Vintturi) in the 1960s, which were continued in the1980s by Paraisten Kalkki Oy. During 2004-2008, the Geological Survey of Finland (GTK) investigated the deposit using geological boulder mapping, a geophysical ground survey and diamond drilling of 2032 meters. The Leviäkangas spodumene pegmatite strikes NNW – SSE, dips 40 – 60º to the SWW and varies in thickness from one to 20 meter along its inferred length of 500 m. We used Gemcom GEMS software to carry out 3D -modelling and a mineral resource assessment of the deposit, using assays from 101 diamond drill core samples. We first estimated the indicated mineral resources by solid modelling. Details of indicated resources were estimated by block modelling using a 2x2x2m block size. On the basis of solid modelling, the Leviäkangas deposit contains a 2.1 Mt mineral resource with 0.70 wt % Li2O (Table 1). On the basis of block modelling it contains a 2.1 Mt mineral resource with 0.85 wt % Li2O for a 0.0 % Li2O cut off, or a 0.5 Mt mineral resource with 1.09 wt % Li2O for a 1.0 % Li2O cut off (Table 1). We applied the recommendations of the Finnish Association of Mining and Metallurgical Engineers to the classifications used. The assessments are consistent with JORC and EFG standards. The deposit is still open at depth, north and south, and, hence, it is possible that the present resource assessment will prove to be conservative with respect to ton-nage.

Mineral resource assessment and 3D modelling of the Leviäkangas lithium deposit, Western Finland Tiivistelmä

Leviäkankaan litium esiintymä sijaitsee Kaustisilla, Länsi-Suomessa, noin 55 km Kokkolasta kaakkoon. Esiintymä sijoittuu Pohjanmaan liuskevyöhykkeeseen Keski-Suomen graniittikompleksin ja Vaasan migmatiittikompleksin väliin. Leviäkengas I -niminen valtaus (kaivosrekisterinumero 8390/1) on laajuudeltaan 90 hehtaaria. Suomen Mi-neraali Oy teki Leviäkankaalla litiumpegmatiittitutkimuksia jo 1960-luvulla, jolloin kohdetta kutsuttiin nimellä Vintturi. Paraisten kalkki Oy jatkoi tutkimuksia 1980-luvulla. Vuosina 2004 – 2008 Geologian tutkimuskeskus (GTK) selvitti aihetta lohkarekartoituksin ja geofysikaalisin maastomittauksin ja syväkairaamalla 2032 m. Tutki-muksissa Leviäkankaalta on paikannettu noin 500 m pitkä, NNW – SSE suuntainen spodumeenipegmatiittijuoni, jolla on paksuutta yhdestä kahteenkymmeneen metriin ja jonka kaade on 40 – 60 astetta SWW. Esiintymä 3D-mallinnettiin ja mineraalivaranto arviointiin Gemcom GEMS-ohjelmistoa käyttäen kairausten ja 101 kairanäyteanalyysin perusteella. Todennäköiset varannot arvioitiin ensin solidimenentelmällä. Sen jälkeen varanto-ja arvioitiin varantokäyrät mahdollistavalla blokkimenetelmällä solidien sisällä käyttäen 2x2x2 metrin blokkiko-koa. Solidimallinnuksen perusteella Leviäkankaan esiintymän mineraalivaranto on 2,1 Mt Li2O -keskipitoisuuden ollessa 0,70 wt % (taulukko 1). Blokkimallinnuksen perusteella esiintymän varanto on 2,1 Mt ja sen keskipitoi-suus 0,85 wt % Li2O, kun raja-arvona on 0,0 % Li2O (taulukko 1). Kun raja-arvo asetetaan 1,0 prosenttiin Li2O- varanto on 0,5 Mt ja sen keskipitoisuus 1,09 % Li2O. Vuorimiesyhdistyksen suosituksia sovellettiin arvioinnissa ja varantojen luokittelussa. Arvioit noudattavat JORC- ja EFG –standardien vaatimuksia. Esiintymä on rajaamatta etelä- ja pohjoissuunnissa sekä syvyyssuunnassa.

1 INTRODUCTION The Leviäkangas 1 claim area is situated in the municipality of Kaustinen in Western Finland (Fig. 1), about 55 km SE of the city of Kokkola. The KKJ base map sheet is 2323 08D and the KKJ Zone 2 coordinates are 7059594 (X) and 2486713 (Y), corresponding to the EUREF-FIN geographic coordinates of (Lat.) 63° 38.239' and (Long.) 23° 43.697'. The UTM map sheet is Q4113B. General information about the Leviäkangas 1 claim is given in Table 1.

title Leviäkangas 1 mining register number 8390/1 area 90 ha registration date 19.11.2008 expiry date 19.11.2013


The terrain in the Leviäkangas claim area is characterized by mires, the quaternary deposits be-ing mainly peat and till. The forests are mainly young Scots pine. According to the drillings in the Leviäkangas, the thickness of the quaternary deposits varies from 3.2 meters to 10.0 meters. There are no lakes or ponds. The Köyhäjoki River in the south gathers the waters from mire ditches. According to till studies in the area, the level of the groundwater is at a depth of three meters.

There are no conservation areas in the Leviäkangas claim area. The closest conservation is the Vionneva protected area (FI1000019), about 6.5 km to the east. Vionneva belongs to EU’s Natura 2000 network of protected areas. A road passes from south to north through the claim area. There is no settlement.

The Leviäkangas lithium pegmatite deposit is situated at the Pohjanmaa Schist Belt, which forms a 350 km long and 70 km wide arc-shaped belt between the Central Finland Granitoid Complex in the east and the Vasa Migmatite Complex in the west (Alviola et al. 2001). Several spodu-mene rich pegmatite boulders SE from Leviäkangas form a boulder fan which previously had led to the discovery of the Leviäkangas spodumene pegmatite in the 1960s (Säynäjärvi 1973). Drill-ing programs performed by Suomen Mineraali Oy, and later by Oy Partek Ab (table 2), resulted in the discoveries of spodumene bearing pegmatite dikes in Leviäkangas (called Vintturi at that time).

GTK’s investigations at Leviäkangas began in early 2004. After reviewing the older data, GTK decided to further investigate the Leviäkangas pegmatites with the objective of outlining their dimensions and lithium potential. The investigations during 2005-2007 included re-logging and analysing drill cores from earlier drilling programs during the period 1965-1980. During early spring 2008 the GTK carried out a 60 samples RC-drilling program. The objective was to locate the pegmatite dike at the surface and to direct diamond drilling. Further research activities in-cluded two drilling programs.

In total, GTK drilled 22 drill holes (2032 m) in the Leviäkangas prospect area in 2006-2008. The drill holes are listed in Table 2. Locations of the drill holes are shown on the geological map in Figure 2 and in Appendix 2. Locations of the RC drillings are shown in Figure 2. The diamond drill core size was 46 mm (T56 bit). We measured the locations of the drill holes afterwards with an accurate (<1 m) GPS device.

The drill cores were logged and photographed (Ahtola 2010, appendix CD) at GTK’s drill core depot in Loppi. We split the cores with a guillotine and sampled half of the core for the assay. The average sample length was two meters. Core logging reports are included in the data CD by Ahtola 2010. We systematically analysed the drill cores of the pegmatite rocks at Labtium Oy in Espoo using the X-ray fluorescence (XRF) method (method code 175X). Determinations are made from pressed powder pellets. We determined the amount of lithium and other REE ele-ments using the ICP-MS method 307P/M ( HF-HClO4 digestion). During 2005–2008, we ana-lysed 128 samples; of these, 101 of the samples were from spodumene pegmatites. The results of the chemical analyses are listed and the analysis methods explained in the appendix CD by Ah-tola 2010. We conducted mineralogical studies on six polished thin sections from the Leviäkan-gas spodumene pegmatites. After identifying the main minerals with a polarizing microscope, we determined their chemical composition using a Cameca SX100 microanalyser.

There are no outcrops in the Leviäkangas prospect area. The general geological outlines are based on information obtained by diamond drilling and ground geophysical surveys. The spodu-mene pegmatite is intruded mainly into mica schist that has some greywacke parts. The main minerals in the spodumene pegmatites are spodumene, albite, quartz, K-feldspar and muscovite. The spodumene grains are unevenly distributed in the dike and, in some cases, completely trans-formed into white mica. In most cases, the spodumene content increases from the wall rock con-tact toward the core section of the dike.

Ahtola et al. (2010) describes the geography and general property, environmental statement, the exploration history, exploration data and the geology and mineralogy of the prospect in detail.

This report describes 3D modelling and a mineral resource assessment of the Leviäkangas de-posit based on the diamond drill core assay data presented in Appendix 1. Locations of the dia-mond drill holes and vertical sections are presented in Appendix 2. Lithologies, lithium assay histograms and lithium composites are presented in the vertical sections in Appendix 3.

2 STATISTICAL ANALYSIS AND COMPOSITING OF THE DATA

2.1 Statistical parameters and a histogram of Li2O

We analysed 128 drill core samples, of which 101 were spodumene pegmatites (Appendix 1). The total length of the drill cores and the total length of the spodumene pegmatites in the drill cores are presented in table 3. We did not analyse RC drilling samples or include them in this study. The statistical parameters of Li2O, BeO, and Nb2O5 and the Ta2O5 contents in the ana-lysed spodumene pegmatite samples are presented in Table 4. A histogram of the lithium (Li2O) content in the spodumene pegmatite samples is presented in Figure 3.

The 101 spodumenen pegmatite assays of the Leviäkangas prospect have an average grade of 0.74% Li2O, 173 ppm BeO, 81 ppm Nb2O5 and 67 ppm Ta2O5. The distribution of lithium is nearly normal (Fig. 3). According to the histogram, there are no distinct populations in the data,


except for the peak at very low values, which comes from results below the detection limits of the chemical analysis method used.

2.2 Compositing of the data

We composited the 101 spodumene pegmatite assays of the Leviäkangas prospect along the length of the diamond drill holes. We weighted the grades by sample lengths and the maximum length of an accepted sample with a Li2O less than 0.02%, was 2 metres.

Table 5. Statistics of the composited assays:

For a cut-off value of 0.02% Li2O, there are 27 composites with a total length of 192.51 m and an average grade 0.66% Li2O, 175 ppm BeO, 81 ppm Nb2O5 and 67 ppm Ta2O5 (table 5). The average length of the composites is 7.13 m.


3 3D MODELLING AND MINERAL RESOURCE ASSESSMENT We did 3D modelling and a preliminary mineral resource assessment for the Leviäkangas deposit in two ways: first, by solid modelling using conventional sectional geological outlining of the mineralized bodies as polygons, and second, by block modelling. We limited the modelling to the most uniform part of the deposit at sections PR VIIII – PR XIII.

We modelled topographic and bedrock surfaces using diamond-drill-hole survey data and a Laplace interpolation method (Gemcom GEMS). Estimations of the surfaces are less reliable far-ther from the positions of the drill collars.

Based on two spodumene pegmatite boulder sample measurements, we used a density of 2.75 g/cm3 for tonnage calculations.

We applied the recommendations of the Finnish Association of Mining and Metallurgical Engi-neers to the methods and classifications used and the assessments are consistent with JORC and EFG standards.

3.1 Solid modelling

To solid model the mineralisation, we first studied the intersections of the ore at various sections by compositing the assays. Next, we interpreted the outlines of the mineral deposit at various sections and, finally, connected the interpretations to form the 3D solids.

We calculated the average grades for intersections (compositing in GEMCOM) as follows:

− we weighted the grades by sample lengths

− we used a cut-off grade of 0.02% Li2O in selecting samples for the calculations

− the maximum length of an accepted sample with a Li2O less than 0.02% was 2 metre.

The statistical parameters of the oxide values in the spodumene samples of the modelled dikes are presented in Table 6 and statistics for the composited values in Table 7.

We conducted geological outlining (polygons) of the mineral deposit on vertical sections with the aim of determining the indicated resources as realistically as possible. The outlining followed precisely the composited assays and extended downwards to z = -100 at section PR_XI and to z = -50 at the other sections (Figure 4). Where composites could not be connected from one drill hole to another at a particular section, we extended the outlining to the midway point of the drill holes. So, we set the range of influence at these sections conservatively to 50 meters, at section PR_VIII to 85 m and at section PR_XII to 80 m. There are 2-4 drill-hole intersections at the modelled sections. To combine 3D solid model of the deposit, we connected outlines of mineral-ized zones from section to section in the horizontal direction. If the outlines could not be con-nected from section to section, we extended the solid to the midpoint of the sections.

Modelling produced a major dike of a length of 500 m extending from section PR_VIIII to sec-tion PR_XIII, and 5 minor dikes (figure 5) in the vicinity of the main dike. The strike of the de-posit is from NNW to SSE (165 degrees) with a dip of 45 degrees to the SWW on average. The solid model shows a total mineral resource of 2.1 Mt with a density of 2.75 g/cm3. The average grades of the composites in Table 7 also represent the average grades of the solid model.

3.2 Block modelling

For a more detailed mineral resource assessment using the block modelling method, we divided the deposit and its surroundings into 2x2x2 m blocks. We interpolated the average grades for each block using the inverse distance method. We weighted the drill core assays using the in-verse of the square of a distance (ID2). The trend of the mineralization is roughly NNW-SSE (165 degrees) with a dip of 45 to the SSW. The ranges of influences were 100 m in the direction of the trend, 100 m in the direction of the dip (45 degrees SWW) and 10 m perpendicular to the modelled plane of the dikes.

The distribution of the average grade of Li2O in blocks is presented as a projection on a planview in Figure 6. Resource blocks inside the main dike are presented as a 3D view in Figure 7.

The total tonnage of the blocks having a Li2O content over 0% is 2.1 Mt with a Li2O content of 0.83 %, a BeO content of 171 ppm, a Nb2O5 content of 84 ppm and a Ta2O5 content of 69 ppm. A summary of the mineral resource assessment by block modelling is presented in Table 8. Ton-nage and grade curves are presented as a function of the cut-off grade in Figure 8.

4 DISCUSSION Drilling has confirmed a fairly continuous 500 m long zone of spodumene pegmatite dikes strik-ing NNW-SSE in the Leviäkangas area. 3D modelling and mineral resource assessment of the Leviäkangas deposit was done in two steps: first, by solid modelling and, next, by block model-ling inside the solids. The solids represent a 3D interpretation of the lithium mineralisation. We studied the resources in detail by block modelling to produce the resource curves.

Solid modelling produced a 500 m long and 2-20 m wide major dike extending from section PR_VIIII to section PR_XIII and 5 minor dikes in the vicinity of the main dike. The strike of the deposit is from NNW to SSE (165 degrees) with a dip of 45 degrees on average to the SWW.

On the basis of solid modelling, the Leviäkangas deposit contains a 2.1Mt indicated mineral re-source with 0.70 wt% Li2O. On the basis of block modelling, it contains a 2.1 Mt indicated min-eral resource with 0.85 wt% Li2O with a cut off for Li2O at 0.0 wt%, or a 0.5 Mt indicated min-eral resource with 1.09 wt% Li2O with a cut off for Li2O at 1.0 wt%. Because of the poor sam-ple grid, only 30% of the indicated resources might be classified as a measured resource. Block modelling with the inverse distance method tends to give higher grades compared to the assay composites which present average values for the solid model. The difference is due to different methods of calculation.

The reliability of the modelling and assessment can be evaluated by observing the drill profiles where the original assays and the interpretation of mineral occurrence is presented (App. 2). Distances of 100 m from section to section are fairly long. There are 2-4 drill-hole intersections at the modelled sections. We could not take the effects of faulting and other geological con-straints into consideration in the resource calculations provided here. Although the mineralisa-tion seems to have a fairly good continuity, more drill core samples are needed for a more reli-able resource assessment and 3D modelling.

We applied the recommendations of the Finnish Association of Mining and Metallurgical Engi-neers to the classifications used. The assessments and related investigations are consistent with JORC and EFG standards. The occurrence is open to the NNW, to the SSE and downwards, and, hence, it is possible that the present resource assessment will prove to be conservative with re-spect to tonnage.
