•Lucapa seeks origin of its recent finds, among world's biggest
•Company may look to London investors to fund mining operation
The diamond explorers known for discovering some of the world’s most-valuable gems in recent years, including a 404-carat stone sold last month, say they’re closing in on the source of their finds.
Lucapa Diamond Co., the Perth, Australia-based company that’s unearthed a stream of discoveries sifting through Angola’s gem-rich soil, is using cash from such sales to seek the “kimberlite” diamond-bearing rock where the stones probably originated.
“We’re finding some of the very best diamonds in the world,” Chief Executive Officer Stephen Wetherall said in an interview in London. “It’s telling us there is something big close by.”
Lucapa are currently alluvial miners, combing for diamonds that have been washed out of the kimberlite core. However, about 85 percent of the world’s diamonds are found by directly mining the cores, carrot-shaped pipes formed when violent explosions forced molten rock from the Earth’s mantle up to the surface, carrying a diamond lode.
Tell-Tale Signs
This is what Lucapa is hoping for next. While alluvial gems are easier to mine, it’s hard to tell how long any deposit will last. Hitting kimberlite is where the big money is made.
The CEO and his team say they’re finding tell-tale signs of kimberlite beneath the area they’re currently mining. Using cash from their share of the $16.7 million raised from the 404-carat diamond, the biggest ever found in Angola, the company is bringing in drill rigs and hopes for a better idea of what they have by the end of the second quarter.
Lucapa has also discovered five more gems greater than 50 carats this year.
Discovering kimberlite is no guarantee of success. Of the more than 6,000 such pipes that have been tested in the past 140 years, only 60 have been worthwhile mining, according to De Beers, the former monopolist and still the biggest producer of diamonds. No more then 10 of those have been so-called super deposits, capable of shifting global supply.
Another obstacle is Angola, not always an easy place to operate. De Beers has cut back its operations there, while BHP Billiton Ltd., Petra Diamonds Ltd. and Trans Hex Group Ltd. also surrendered deposits in the past. Producers must sell their stones through Angola’s Sodiam state marketing unit, resulting in discount prices relative to global trading hubs.
Should Lucapa find the conditions it’s seeking, the Australian-listed miner will probably look to London and its mining-investor base to fund the expensive business of building a mine.
“London understands diamonds and London has the pockets,” Wetherall said.

Lucapa Diamond – Neues Diamantabbaugebiet erweist sich als sehr ergiebig
Geschrieben von Björn Junker • 12. April 2016 • Druckversion
Der australische Diamantproduzent Lucapa Diamond (WKN A0M6U8 / ASX LOM) hat sich auf seiner Lulo-Konzession in Angola ein weiteres Abbaugebiet erschlossen. Auf den Alluvialterrassen mit der Bezeichnung E46 führt das Unternehmen derzeit einen Testabbau durch – und schon der fördert regelmäßig besonders große und auch farbige Diamanten zutage!
Bereits Ende März hatte Lucapa den Fund von acht speziellen Diamanten (einzelne Steine mit einem Gewicht über 10,8 Karat) gemeldet, darunter auch ein Stein mit 68 Karat von höchster Qualität. Und nun kommen weitere wertvolle Diamanten hinzu, unter anderem ein 59-Karäter vom Typ I sowie ein 33-karätiger Diamant vom besonders wertvollen Typ IIa (D-colour) – also ein Schmuckstein!
Sehr viel versprechend ist auch, dass Lucapa auf E46 zahlreiche rosafarbene Diamanten gefunden hat, darunter ein intensiv rosafarbener 0,2-karätiger Diamant. Diese Funde rosafarbener Diamanten sowie die Entdeckung eines 4-karätigen rosafarbenen Diamanten, während des ursprünglichen Großprobenprogramms deuten darauf hin, dass der gesamte Diamantenbestand farbige Diamanten sowie große Schmucksteine von hoher Qualität enthalten sollte!
Bislang hatte Lucapa sich auf die Abbaugebiete Block 8 und 6 konzentriert, wo man zahlreiche große Diamanten entdeckt hat, darunter auch den mit 404 Karat größten, jemals in Angola gefundenen solchen Edelstein. Und da sich nun auch E46 als Produzent von speziellen Diamanten mit Schmucksteinqualität erwiesen hat, wird immer deutlicher, dass die Lulo-Liegenschaft im Zentrum einer großen Diamantenprovinz liegt.
Und darüber hinaus liegt E46 in unmittelbarer Nähe der bekannten Diamanten führenden Kimberlite L46 und L19, wo man während der Beprobungsphase zwei Typ I Kimberlitdiamanten mit einem Gewicht von 1,24 Karat entdeckte.
Insgesamt zeigt sich also, dass auch E46 zu einem sehr ergiebigen Abbaugebiet für Lucapa werden könnte. Was umso wichtiger wäre, da dieses Gebiet im Gegensatz zu Block 8 und 6 auch während der – derzeit noch vorherrschenden – Regenzeit zugänglich ist.

MORE LARGE SPECIAL DIAMONDS AND PINKS FROM NEWAREA AT LULO
- Latest trial mining recoveries from E46 include 59 carat and 33 carat specials and more pink diamonds
Lucapa Diamond Company Limited (ASX: LOM) (“Lucapa” or “the Company”) and its partners are pleased to announce the recovery of more large specials and fancy-coloured diamonds from trial mining of the E46 alluvial terraces at the Lulo Diamond Project in Angola.
As announced to the ASX on 29 March 2016, Lucapa and its partners recovered eight special diamonds
(individual stones weighing more than 10.8 carats) from trial mining of the E46 alluvial terraces at Lulo,
including a 68 carat Type IIa D-colour gem.
The latest special diamond recoveries from E46 include a 59 carat Type I diamond and a 33 carat Type IIa D colour gem.
In addition, Lucapa and its partners have recovered a number of pink diamonds from E46, including an intense-fancy 0.2 carat pink.
These pink recoveries - together with the 4 carat pink recovered in the original exploration bulk sampling program - suggest the E46 diamond population should include fancy-coloured diamonds as well as large, high-quality gems.
As noted in the ASX announcement of 29 March 2016, E46 is located ~10km usptream of alluvial Mining Blocks 6 and 8 (Figure 1), which have been the source of frequent special diamond recoveries of up to 404 carats.
E46 is the fourth area along a ~20km stretch of the Cacuilo River terraces to have produced special, gemquality diamonds, providing further evidence that Lulo is in the heart of a large diamond province (Figure 1).
E46 is also adjacent to the known diamond-bearing L46 and L19 kimberlites. Lucapa recovered two Type I kimberlite diamonds weighing 1.24 carats in 2015 from preliminary bulk sampling at L46 (See ASX announcement 16 October 2015).

Hallo, ich habe gerade auf Hotcopper einen interessanten Beitrag zu Lucapa gelesen. Meines Erachtens fasst er relevante Punkte zusammen und erleichtert eine Einschätzung des Chance-Risikopotentials.
Der Beitrag ist übrigens von dem deutschen Nutzer joergwerda. Schade, dass er hier nicht schreibt.

There are diamonds on the concession. LOM is not only searching for diamonds but there were already significant findings of diamonds on the LULO concession.
Found diamonds are of extreme high quality and value. There is an extraordinary high share of gem-quality diamonds. There is an extraordinary high share of special diamonds >10,8ct. There is an extraordinary high share of type IIa diamonds in perfect quality. In the meantime it is nearly “normal” to find diamonds with more than 100ct in top quality. With the finding of the 404 ct. type IIa diamond LOM found an extraordinary diamond, similar or even bigger findings seem to be possible. Average price per carat for 2015 sales is 1.370AUD/ct with significantly increasing tendency in Q4 2015 and Q1 2016.
Strong indication for source of diamonds close to mining block 8. Indicator minerals as well as the character and consistency of the diamonds found on block 8 most likely point to a source of diamonds being only a few hundred meters up to 1.5km away from the place where diamonds were found. As mining bloc 8 is directly “sitting” on L259, maybe the diamonds are just washed away from one end of L259 to the other end.
Top priority target L259. L259 is a confirmed kimberlite directly under mining block 8. If you look on google maps you can see that the garimperos directly started to dig at the south-western border of L259 and from there they digged the whole river downwards. Did already the garimperos sit on the source? Can life really be so easy? If L259 is really the source of the alluvial diamonds on block 6 and 8 then the source would be a huge kimberlite, much bigger than most other diamond mines in the world. Overall there is a good chance to build up a very exceptional diamond mine which might become one of the leading mines in the the world (some very optimistic people even say .most valuable mine in the world)
Multiple chances. LOM has several chances to “win the jackpot”. L259 is a possible source for diamonds on mining block 6 and 8. L46 might be the source of the diamonds on the alluvial terraces E46. Until now only some kimberlites around Cacuilo river are examined. Kimberlites at Lulo river are not yet touched. LOM has got an exploration licence in Botswana. So there are several chances. Maybe it is even possible to win the jackpot twice or three times.
High potential for share price as soon as economic kimberlite is confirmed. In case that an economic kimberlite is confirmed the share price does not reflect this. So if such confirmation is made there is significant potential for the share price.
Management experience and skills. Top management of LOM is staffed with very experienced persons coming from big mining and diamond companies. So the management knows the business and has a lot of experience how to start such an enterprise.
There is a well-thought plan that will be followed. There is a systematic and well-thought approach of how to do the exploration and the ramp up of the mining. The steps will be announced and as far as I can judge will be followed without big surprises.
Constant revenues by alluvial mining. Alluvial mining was started in 2015 and is developing very well. One good mining area after the other is detected. It was generated 12 mill. AUD revenue in 2015, thereof >8 mill. AUD in last quarter. In Q1 2016 the revenue was >30 mill. AUD (mainly caused by the maybe exceptional finding of an 404 ct. diamond but also 9 mill. AUD from other diamonds). If I project this for the future I assume a yearly revenue between 30 mill. AUD and 120 mill. AUD. If production capacity will be doubled as announced this means yearly revenue from alluvial mining between 60 mill. AUD and 240. mill. AUD p.a. This limits the risk for the share price as well as provides significant cash flow for kimberlite exploration.
Huge number of kimberlites. Lucapa has identified nearly 300 potential kimberlite targets. I have read that in average every 100th kimberlite is an economic pipe. Just as a statistic average this would mean 3 economic pipes on LOMs concession.
Already confirmed diamondiferous kimberlites. There are already five confirmed diamondiferous kimberlites on the concession. Ok, one confirmation is just based on the finding of a micro diamond.
Good geological situation. Well I am not an expert but what I have read is that it might be that LOM is sitting on an excellent place to find diamonds.
Good relation to local authorities. LOM always states the good relations to Angolan government and the joint venture partner Endiama.
Angola tries to attract investors for mining activities, especially for diamond mining. Angola has announced that they will significantly increase their diamond production.
Gazzetting should not be a problem. A lot of people see a big risk resp. see the gazzetting as an important milestone. I don’t understand why. Yes exploration licences will extend this or next month. But why should there be no extension, especially when LOM is progressing so well as they did in the past. Alluvial mining licence is already granted for 35 years. Kimberlite mining licence does not make sense as long as there is no confirmed economic kimberlite. So I don’t see that gazzetting is more than a pro forma action.
Little labor costs. Labor costs in Angola are significantly lower than in Europe, Australia or USA.
Positive prognosis on long term diamond price development. In the next years there are expected decreasing production capacities in diamond mining due to the fact that a lot of mines are finally exploited. This may result in increasing prices for Diamonds.

Antwort auf Beitrag Nr.: 52.071.854 von tpnl am 29.03.16 07:30:01also, wenn ich mir die News durchlese, habe ich das Gefühl, dass die Quelle für E46 dann eher Kimberlit L46 sein könnte - so wie das in der Mitteilung nebeneinander gestellt wird...
News:
68.1 CARAT GEM QUALITY DIAMOND RECOVERED FROM
TRIAL MINING IN NEWAREA AT LULO
- Latest large special diamond recoveries at E46 are ~10km from the mining area which
produced gems of up to 404 carats, providing further evidence that Lulo is in the heart of
a large diamond province
Key Points
68.1 carat Type IIA D-colour gem among eight special diamonds recovered from recent trial
mining of E46 alluvial terraces at Lulo
Lucapa and its partners have now identified four areas spanning ~20km known to produce
large valuable alluvial diamonds – Mining Blocks 6, 8 and 31 and E46 alluvial terraces
E46 is ~10km upstream from alluvial Mining Blocks 8 and 6, which have produced special
diamonds regularly including the biggest diamond ever recorded in Angola (404 carats)
The latest E46 special recoveries in the middle of the Lulo mining licence increase
management’s confidence that the large valuable diamonds should continue to be
recovered along the 51kmstretch of the Cacuilo River
Funde, die Fragen aufwerfen:
Haben diese neuen Diamanten die gleiche Quelle?
Kann die dann noch L259 sein (eher nicht)?
Was lässt sich alleine alluvial auf dem Gebietz von Lucapa alles finden?
Erstaunlich und höchst ungegewöhnlich.
Erfreulich aber auch noch mal komplexer als erhofft.

Erstaunlich und höchst ungegewöhnlich.
Erfreulich aber auch noch mal komplexer als erhofft.
Und noch mal ecat88 aus hotcopper zur Einordnung, was gerade hinsichtlich L259 passiert und vor allem was nicht passiert:
The geophysical survey modelling estimates that the top 35-100 metres of L259 is low-density (softer). I interpret this as the top 100 metres being layers of sediment overburden, Resedimented Volcaniclastic Kimberlite (RVK), and low-density weathered Pyroclastic Kimberlite (PK). Deeper than 100 metres, you will start hitting the harder and denser unweathered kimberlite. Previous trenching of the area showed the RVK to be around 6-10 metres deep. Unlike L251, the EM results of kimberlite L259 showed that the majority of the RVK was in the central areas. This suggests to me that the shallower outer rim RVK has been eroded and washed away. This is a good sign as weathering and erosion are the processes for a kimberlite to release its diamonds. But it also means that some of the prospective bulk sampling areas are still affected by the wet season though there are still some areas they can start drilling on the outer rim which sits higher.
The landcruiser drill rig is rather lightweight in terms of drill rigs so it will be used more for reconnaissance sampling of the shallow geology structures. This is fine as the top 100 metres of L259 is low-density as previously mentioned so this drill-rig is fit for purpose. It will have two types of kimberlite drilling roles.
The first is delineation drilling to identify any shallow areas of PK that are suitable for bulk sampling. The shallower the better. If they can find a shallow outcrop of PK, they can start the bulk sampling fairly quickly. The EM has already identified some good drill targets.
The second is to take research core samples to be taken to the lab for micro-probing analysis. This is important as they are trying to gain as much data on this kimbo as possible. L259 is huge so by taking samples from various points, they will be able to get a better idea of which parts are more prospective for diamonds. They will compare the lab results from the various sample points and look for indicators such as the presence of micro-diamonds and G10D garnets which identify which sections of kimberlite were derived from the diamond-stability zone of the mantle.
All this scheduled to start April so not too far away. After they have gathered the required shallow geology data and done their interpretation, they will probably hire heavier drill gear to test the deeper sections of L259. The lightweight landcruiser drill rig can then be used to help with the resource extension work of the alluvial fields so I believe it is an excellent investment.

1S1, the results said the thickness (not the depth) of the low density zone was estimated between 35 and 100 metres. There was no suggestion that the PK was 35 metres deep minimum. RVK was around 6-10 metres deep in the central zone so I think there is a chance of shallow kimberlite in the outer areas. EM is only an interpretation, drilling will tell you the real deal so we need to wait for that. Shallow delineation drilling on a low density target can be done rapidly so they can cover a lot of ground.
The chances for a short-term price spike is more likely to come from gazetting which I suspect will be finalized in April as the kimberlite exploration licence is due for renewal in May. Don't underestimate MK, he is a wily old fox and I'm sure he has an Ace up his sleeve to play in April to maximise LOMOB conversions.

The geophysical survey modelling estimates that the top 35-100 metres of L259 is low-density (softer). I interpret this as the top 100 metres being layers of sediment overburden, Resedimented Volcaniclastic Kimberlite (RVK), and low-density weathered Pyroclastic Kimberlite (PK). Deeper than 100 metres, you will start hitting the harder and denser unweathered kimberlite. Previous trenching of the area showed the RVK to be around 6-10 metres deep. Unlike L251, the EM results of kimberlite L259 showed that the majority of the RVK was in the central areas. This suggests to me that the shallower outer rim RVK has been eroded and washed away.
