The drilling, on the Sivakkalehto target, comprised three 60 degree angled scoutholes at 200m intervals along the strike of the central part of a north-easttrending ground magnetic anomaly. The drill holes were between 101m and 126.5mlong. Sampling of the drill core for analysis was initially carried out to confirmvisual estimation of magnetite content and some of the mineralised intervalshave not yet been sampled. The following table summarises assay results andmineralised sections not yet assayed. Visual estimates correspond well with theassay results received and allow the additional comments on iron mineralisedintervals and grade to be included in the accompanying table of results. The 17-34% iron intervals reported in the table below represent magnetitecontents of approximately 25-50%. Normally, magnetite can be concentrated to asaleable product grading 67% iron or more. Tertiary's initial drill holes were shallow with only a single hole drilled oneach profile. Holes 07TS2 and 07TS3 both collared in bedrock mineralisation(beneath a cover of overburden) and also ended in mineralisation. This suggeststhat the mineralised units could be significantly wider than the intervalspenetrated by these holes. Hole 07TS1 also intersected a zone of weak coppermineralisation and gold values in all three holes were generally low. Based on these initial results the Company is now targeting a large body ofopen-pittable magnetite mineralisation with magnetite content in the 30-50%range. A similar such orebody - the Southdown Magnetite deposit in WesternAustralia - is currently being developed by Grange Resources(www.grangeresources.com.au) based on a resource of 400mt at 37% magnetite. Tertiary's Chairman Patrick Cheetham commented: "We are very pleased with theseresults. They indicate the possible presence of a large body of ironmineralisation at commercial grades." Further assaying of the core will now be undertaken and follow-up drilling isbeing planned. Further info: Patrick Cheetham, Executive Chairman, Tertiary Minerals plc.
