Sunrise Diamonds - the spin off of Tertairy Minerals potentially Diamond bearing kimberlite fields in Finland will launch on the AIM, 6th June after being hugely oversubscribed. Tertiary will retain a stake in Sunrise.

TYMs last drill report confirms the findings of a highly promising find and the capital raised will fund critical phase 2 trials leading to potential industrial level production. The field is enormous containing numerous targets...expect an audacious debut and get on early if you can. The likelihood of a positive find is high.....read on from the company's technical report...

Study Confirms Kimberlites Tapped Diamond-Favourable Source Rocks
Claim Holding Extended To Total 30 Untested Targets
Possible Link To Russian/Arkhangelsk Diamond Fields
Tertiary Minerals plc (the Company) is pleased to report the positive findings of an independent study on the diamond potential of its Kuusamo kimberlite project in Northern Finland.

The report has been prepared by an international kimberlite specialist at the Geological Survey of Finland (GTK). The data in the report is based on relatively limited sampling of the three kimberlites discovered so far but supports the following important conclusions:

the geological conditions considered necessary for the occurrence of diamondiferous kimberlites occur in the Kuusamo area
the newly discovered kimberlites have tapped the diamond stability field of the earths mantle
the mantle tapped by the kimberlites contain both types of potential diamond-hosting mantle materials - harzburgite and eclogite and the mantle has not been affected by diamond destroying processes.
The statistics for kimberlite clusters show that any given cluster can contain a spectrum of kimberlite from those containing no microdiamonds to those with commercial diamond contents. Similarly individual kimberlite intrusions can be multi-phase, with some phases containing diamonds, others none.

The GTK report concludes that the lack of micro-diamonds in the kimberlite samples tested to date does not necessarily limit the prospectivity of any future kimberlite discoveries in the area.

The report also concludes that the results are .exciting in that it is likely that an entirely new cluster of kimberlites (the Kuusamo cluster) has been discovered and that typically there are 10-50 kimberlites in a cluster.

Tertiary considers that the results of the GTK study considerably enhance the potential of the untested targets in the Kuusamo area. The company has recently expanded its claims and claim reservations and now has a further 11 targets (total of 30) under claim or claim reservation in addition to Kalettomanpuro and Kattaisenvaara and existing data strongly suggest that more kimberlites will be discovered.

The report speculates that the Group I Kuusamo kimberlites may have a similar Devonian age to kimberlites found near Arkhangelsk in Russia, also in the Karelian Craton that includes the Lomonosov diamond project run by Alrosa and the highly diamondiferous Grib pipe.

This speculation is based principally on the position of the Kuusamo cluster on the southern margin of the same Devonian kimberlite and alkaline province that stretches for over a 1,000 km from Northern Finland through the diamond bearing regions of Kandalaksha, Terskii Bereg, Arkhangeslsk and Central Timan in NW Russia.

Technical Note (to accompany New Release of 4 November 2004)

The background to Tertiarys new discoveries is given in various news releases made since January this year. Three separate kimberlites have been intersected in drilling - two at the Kalettomanpuro (KP) site and one at Kattaisenvaara (KV) some 20km away.

It is accepted wisdom that many diamonds (a form of carbon) grew as crystals in the primeval earth as all harzburgitic diamonds are over 3 billion years old. Over time diamonds are only preserved where diamond is stable in preference to graphite (at high pressure and relatively low temperature) and this is usually beneath the old stable parts of the earths crust (cratons) where there is a thick, cool and stable lithospheric mantle keel the so-called diamond stability window. In such windows diamonds are found in mantle containing the rock types harzburgite or eclogite. For diamonds to be found at the surface kimberlitic magma must have risen to the surface through the diamond stability field of the mantle, on the way collecting pieces of the diamond host-rocks, harzburgite and eclogite. As the kimberlite magma ascends these pieces are disrupted, liberating the diamonds. The kimberlite magma must ascend rapidly enough so that the diamonds are preserved in otherwise unstable conditions in the crust.

Thus there are two main pre-requisites for the occurrence of diamonds at or near the earths surface:

Favourable mantle conditions for diamond preservation through geological time (a source of diamonds)
A transport medium (kimberlite magma) that taps the diamond stability field and both collects and preserves the diamonds.
As kimberlites are the main transport medium, a study of the mineralogy and mineral chemistry of kimberlites in any given cluster will provide information on whether that cluster has diamond potential.

The main technical findings of the GTK study are as follows:

The proximity of the Group I kimberlites to Devonian (365 Ma) alkaline complexes, in particular the Iivaara intrusion, raises the possibility that these new kimberlite discoveries are similar in age to those found near Arkhangelsk in Russia
The Group II Kalettomanpuro kimberlite has petrological similarities to the kimberlites in the 1200 Ma Kuhmo cluster, an area currently being explored by European Diamonds Plc and Karelian Diamond Resources Plc, some 150km to the south
The mineralogy and chemistry of phlogopite mica in the kimberlites confirms the original identification as hypabyssal Group I and Group II kimberlites (end member types of kimberlite, both can contain diamonds)
The Group II kimberlite from Kalettomapuro contains significant amounts of G10 (harzburgite) garnets and G9 (lherzolite) garnets and a high ratio of G10/G9. As harzburgite is known to be one of the main diamond source rocks, this indicates a high diamond potential
Compositional data and thermobarometry studies indicate that mantle-derived G10 garnets are derived almost exclusively from the diamond stable portion of the earths mantle
The Group I kimberlites contain both eclogite grains and eclogite xenoliths (eclogite in the mantle is the other main source for diamonds). So far, however, these are of relatively low sodium garnet type
Picroilmenite and pyrope garnet compositional data indicate that metasomatism has not significantly affected the mantle - another positive factor for diamond preservation
Chromites for the KV Group 1 kimberlite plot in compositional fields that indicate shallow sampling
Group 1 kimberlites so far examined show evidence of fractionation implying slower transport to the surface which, in the case of these kimberlites only, suggests any contained diamonds may have been resorbed

you asking the Kat or anyone? i personally havent a clue, no doubt the Kat will say about 100 quid by t time, lol.

its a rocket, but 10p has been reached too late lads

now you tell me!

i really should get out of the share game....

wait for 8p and then second rally to 12p ;-)

cheers - i already bought at 10p

i'll sell at 12 if it goes there by the end of the day.

what do you think the long term prospects are?

you can buy at 8.61p now

10p is minimum... 15p is quite possible but will take a week or so

Wicked rollercoaster :p

Thanks Kat

any other tips for the short to medium term?

TFC tomorrow, expecting trading update and new contract signed... but I am guessing, its certainly bottomed

if your in at 10p you may as well get more to average down.. looks like buyers are returning

eh up, its going up

i think i'm going to hold on a bit longer til the end of the week - i can't see it going lower..... famous last words.

well the papers will certainly mention it ;-) 15p could be sooner rather than later, its all good news

Easy money this one....

666

10p minimum per the rns... cant really see why these dipped at all actually

rooting for you on this one Kat, it would be nice to see at least one of your many predictions come true.

Quick intra sell offs...

Like the okey kokey... 'Ya put ya money in, ya take ya money out, in - out - in - out de de da da de da'...

666

youve gone cookcoo

Naaa...

Just have fun makin' money...
