Technical report of the Kevitsa drill core logging in 2006

Abstract

Geological Survey of Finland (GTK) was retained by the Scandinavian Minerals Ltd (SM) in March 2006 to carry out core logging including RQD determination and alpha and beta measurements of the oriented core. The core was also photographed by digital camera. Rock density was measured at 5 m intervals. The total length of core logged amounted to 11,353.80 meters and total amount of α and β readings were 5,885 from the 6 oriented holes. Supervision and logging of at least 10% of the core was agreed to be done by a qualified person, who finally logged 1,541.20 m of the core. The entire logging programme was completed on 20th of October 2006. In summary it is concluded that the visual logging gives adequate and sufficient enough information of rock type and gives appropriate background for the geological and ore resources modelling.

1 GENERAL Geological Survey of Finland (GTK) was retained by the Scandinavian Minerals Ltd (SM) in March 2006 to carry out core logging including RQD determination and alpha and beta meas-urements of the oriented core. The core was also photographed by digital camera. Rock density was measured at 5 m intervals. The total length of core logged amounted to 11,353.80 meters (Table 2, lithological log and RQD) and total amount of α and β readings were 5,885 from the 6 oriented holes. Supervision and logging of at least 10 % of the core was agreed to be done by a qualified person, who finally logged 1,541.20 m of the core. The entire logging programme was completed on 20th of October 2006.

Mr. Martti Melamies Assistant Assisting in core logging, RQD-logging Mr. Seppo Kurttila Assistant Assisting in core logging, RQD-logging Dr. Markku Iljina acted as the supervisor of the Kevitsa core logging project. He also did some of the geological logging and alpha & beta angle measuring from oriented core. Dr. Tuomo Törmänen was responsible for most of the lithological core logging, and together with Mr. Panu Lintinen, taking the alpha and beta measurements from the oriented holes. Mr. Martti Melamies assisted in the logging from March to July and Mr. Seppo Kurttila from the beginning of August till the end of logging at late October.

3 LITHOLOGICAL CORE LOGGING Lithological core logging followed the principles adopted by two former loggers, Dr. Tapani Mutanen from GTK and John Pedersen from SM, who had logged Kevitsa cores of the previous drilling campaigns. In this naming schema the main rock types are olivine pyroxenite (olpx) and metaperidotite (mprd), which is the metamorphosed (hydrated) equivalent of olpx. Minor rock

2 types comprise of various dykes (olivine gabbro diabase, metadiabase), xenoliths (dunite, ser-pentinite, metasediments) and mineral veins (carbonate, amphibole, sulphide).

The log of each hole was written into separate Word template, which was also converted to Ex-cel spreadsheet format. The used template had separate columns for starting depth (from), end depth (to), rock type, legend and visual estimate of the amount of sulphides (1-5 = 1-5 vol.%, 5 also greater than 5 %).

The quality assessment of the lithological logging is discussed in a separate chapter of its own later in the text. After receiving most of the chemical assays the visual sulphide amount estima-tions can be evaluated as follows: Ore grade sulphide mineralisation is generally indicated by a value of 2 or greater in the estimate of visible sulphides. Some visual estimations were also made on the type of mineralisation (regular/Ni-PGE/false ore); generally, only deviations from regular ore type are mentioned. The main ore type (“regular ore”) is characterised by elevated sulphur and medium Ni and Cu values. The so called “false ore” is characterised by high sulphur but low Ni and Cu values. The Ni-PGE ore is characterised by high Ni/Co ratio (> 25-30), Ni > Cu, and more variable (medium to low) sulphur contents.

After comparison with the available new assay results it is evident that the visual estimations should be referred as indicative only, and can both over and underestimate the amount of sul-phides. However, generally they are in accordance with the assay results (amount of sulphur). The Ni-PGE type can’t be identified visually to any degree of reliability in standard core log-ging, and it is therefore recommended that all core should be analysed. The application of hand held analytical instruments for fast first instance identification of different ore types should be considered.

3.1 Quality assessment In order to assess the quality of the rock type identification 20 test samples were taken and each of them were subjected to whole-rock XRF assay and thin section study under transmitted light microscope. The rock name based on cumulus mineralogy was also calculated using petrological research software HSC Geo (http://www.outokumputechnology.com/pages/Page____21783.aspx), which is particularly de-signed to handle mafic-ultramafic cumulates. Summary of the results are depicted in the Table 3.

The main lithological rocks types in the visual logging were olivine pyroxenite and metaperi-dotite as the metamorphic equivalent of the former. In IUGS classification the unaltered rocks are either wehrlites or olivine clinopyroxenites depending the relative abundance of the olivine and pyroxene.

The principle observations when comparing visual and microscopic log are: Samples, which are visually logged as pristine, unaltered cumulate (i.e. olivine pyroxenite) are truly such. Some

samples, which visually had been labelled as metaperidotite were actually rather unaltered cumu-lates, in which bulk of the mineral surfaces were unaffected by the hydration. It is only the for-mation of thin amphibole margins around the cumulus pyroxene crystals and interfingering of this secondary amphibole, which makes the rock to look macroscopically as 'altered'.

The presence plagioclase (up to 10 %) is difficult to note in visual logging and it might have been overlooked in many cases.

The relative amounts of clinopyroxene and olivine is also very difficult to assess macroscopi-cally, most of the samples are, however, pyroxene dominated. Strongly olivine dominated or 'oli-vine only' cumulates have, however, been able to be separated out in the visual logging. Some orthopyroxene is also present in the plagioclase bearing samples, but its amount barely exceeds 10 %.

Calculated cumulus mineralogical names tend to be meso or orthocumulates, and have orthopy-roxene and sometimes also plagioclase in intercumulus phase. Microscopic study reveals, how-ever, that the rock is mostly adcumulate i.e. containing less 7 % of intercumulus material.

In summary it is concluded that despite of the above counted restrictions the visual logging gives adequate and sufficient enough information of rock type and gives appropriate background for the geological and ore resources modelling.

4 RQD (ROCK QUALITY DESIGNATION) LOGGING

In addition to geological core logging, the RQD value was also logged for the entire core drilled. The following procedure was used in RQD-logging:

- Core was mainly logged in 1m intervals.

- RQD was calculated based on the total length of core pieces exceeding 10 cm divided by 100 cm and multiplied by 100, resulting in a percentage value between 0 and 100, i.e. core with no natural fractures has an RQD-value of 100.

Table 4 shows the average and median RQD values for the total length of individual holes. Most of the holes have average RQD values grater than 80 (good) and several have average RQD val-ues grater than 90 (excellent). Two holes, KV-40 and KV-41 have significantly lower average RQD values of 75.2 and 77.7. Figures 1 and 2 show two graphical representations of holes with differing RQD qualities: KV-42 shows generally good rock conditions, whereas KV-40 repre-sents one of the holes with more poor rock conditions.

5 ORIENTED HOLES AND ALPHA AND BETA MEASUREMENTS Six holes (table 2) were selected for oriented sampling by the SM and subsequent measurement of the alpha and beta angles of natural joints. The drilling contractor (Kalajoen Timanttikairaus Oy “KATI”) used the “EZY mark” core orientation system, which uses a sort of “pin cushion” to store the profile of the bottom of the hole (Fig. 3 ).

Figure 3. EZY mark core orientation system and how it measures the profile of the hole bottom. Alpha angle is the angle between core axis and maximum dip vector of the plane of the natural fracture (Fig. 4C). The value for alpha is between 0 and 90 degrees (0 value for fracture along core and 90 for fracture at right angle to the core). Beta angle is the angle between the reference line and maximum dip vector of the fracture, measured clockwise around the core, looking down hole (Fig. 4A and 4B). The value for beta is between 0 and 359 degrees. The reference line is the core orientation mark, which, in this case, refers to the bottom of the hole.

In addition to α and β measurements some γ angles of striations were also measured and indi-cated in the 'remarks' field. One striation was found on slickenside (KV-46) on which the relative movement directions were also detectable. Gamma angle is measured within the plane, between the maximum dip vector and the striation, clockwise and looking downhole (Fig. 4D).

All together, some 5885 measurements were made from the 6 oriented holes (Fig. 5). This num-ber of measurements include both open fractures and a number of unopened defects (i.e. mineral veins). However, for the first oriented hole (KV-28) and part of the second (KV-42) no record was kept on the type and filling of the fracture. Basically, all of the natural breaks/fractures were measured (except were the core was badly fractured and/or crushed), and also most of the un-opened veins were also measured. It was also noted that the olivine pyroxenite has some ten-dency to break along a preferred plane, which was measured, when distinct as “texture”.

11

5.1 Quality assessment In the following we have collected some observations and notions on the accuracy and reliability of the α and β measurements:

- The α angle measurements are fairly straightforward, problems arise mainly from uneven or “bent” fracture plains, in which case the measurement is more or less an average value. In most cases the accuracy is ± 5 degrees (or better).

Measuring the β angle turned out to be more problematic and there are more possible sources of error.

- The biggest uncertainty comes from the unexpected deviations between consecutive orienta-tion marks even though the core can be reliably assembled without gaps. When possible, these “false” or unreliable marks were passed by, especially when it could be correlated to several other orientation marks. These deviations were generally in the range of 10 to 30 degrees, but exceeding 45 degrees in some cases (up to ca 130 degrees in one case).

- One possible explanation could be the orientation method used, which could have problems when the core breaks evenly and at close 90 degree angle to the core axis. In cases like these, there is no distinctive profile for the “needle cushion” to record.

- Another source of error is the drawing of the reference line based on the orientation marks; as the marks are fairly widely separated the line can “wander” a bit. This can cause a deviation of around 0 to 20 degrees (generally probably within 10 degrees).

- The final major error source is the visual definition of the maximum dip vector, which in the case of fairly flat and even surface is relatively easy and accurate to define, but becomes pro-gressively more difficult and uncertain the more uneven the surface becomes. Typically the accuracy is probably around ± 10 degrees or better.

- In Appendix 1 we have separated the oriented intervals, and indicated on how many orienta-tion marks the interval has. In a number of cases the interval is defined by only one orientation mark, and in these cases the orientation and hence the α and β angle measurements are, at least some what suspect.

6 CORE PHOTOGRAPHY AND DENSITY MEASUREMENTS

The core was digitally photographed after the lithological and RQD logging, two boxes at a time, both dry and wet. This was done in order to have a visual record of the hole that can be used to-gether with the lithological logs.

Density measurements were selected as the preferred petrophysical method, since it was deemed to be the best way to discriminate between different types of host rocks. Density measurements were taken at 5 m interval.
