Hi Goldenshamrock

My self I?m an X diamond miner use to dive for them on the west coast South Africa near Namibia and other places all I can help you with are the sings of diamond presence and those are shiny blacks , olivine?s , fossils , dyke and conglomerate but gold sorry don?t know enough about it yet and SL don?t sound safe and I don?t like to run .

Regards
Xavier

Hi Golddigger, Not going to throw away the salmon when fishing for trout. We have a lot of indicator material associated with diamonds, but the best indicator is the diamond itself. The fault lines we have on concession are ultra potassic granite intrusions and being in a maffic / ultra maffic area and with the high zircon presence ( 90, 000 ppb ) in the black sands allows for the probability of kimberlite dykes being present; it is understood that only 1 to 2 % of such dykes are productive. The geology was with reference to the weathering and movement of gold down the slope from its original vein, ultimately ending up as stream / river placer deposits. The area we are in has other interesting products such as titanium and ilemenorutile and rumoured to be U and Pu somewhere in the hills. If I provide the coordinates would it be possible to have copies of maps you mentioned from U of Tx. Possibly can be sent through WinZip or as FTP Thanks for your time Goldenshamrock :

The information on the zircon is interesting... There is a large area, west of my location, that fits the description, above.... I am going to have to look at the geo reports again and see if they have a quote re zircon. To my memory, they do not, because most were done in the late 40s and through the 50s to the early 70s, perhaps this was omitted.

I have found considerable ilmenite and even some kimberlite-like material, over a wide area, there, and I do have some good data access, being a licensed Freeminer. When I am THERE, I keep my eyes open, because of being a rockhound, all my life!

I was not aware of the zircon-kimberlite association, I was awar4e of the ilmenite connection, thanks for the eye-opener. As you may know, Canada has become a hot-bed of diamond exploration, staking, AND now mining.

You see, now, what I said about communications, and how it can be important! Even the tiniest thing can sometimes be sensational.

I have 2 maps, presently and they only come in one size: HUGE! I can send what I have, if you give me an email address... send me a personal message, through this site.

I do not know how much these maps will zip, as they are very detailed, which usually means poor compression, and they both are around 6 megabytes. One covers the north-east quarter of the country and the other covers the south-east quarter and both lap a bit into Guinea.

From what I have been reading, it would pay to have a visa for Guinea, as well as Sierra Leone, in case they needed a back door.... but kind of like *jumping from the fry pan into the fire.*

Let me know, further about the map(s.)

Hi Xavier,

It is unfortunate that Sierra Leone still has this baggage to carry. The war ended some 9 years ago and the Country as peaceful as most, if not better in Region. IA block behind the beach front in Durban or a wrong turn around Hillbrow in Joey can get your heart beating ! North of Namib in Angola I would assume still quite a few land mines lying around and therefore not a place to run in.

We have a lot of the shiny black and some olivines, the fossils side I am not familiar with. Also we pick up a lot of what we call locally Joyce - stones that have the characteristics of diamond by shape, cleavage and density - i.e carbon that has started but not completed the process. Gold is primary objective, but eyes always open for diamonds pgm's etc.

Regards

Hi Golddigger,

When I send off gravels for assay ( Omac Laboraties in Eire ), I also send the black sands from that spot. From that I research as to the grades of material identified. Black sand can start you dreaming too much and an analysis puts it into perspective. Oddly, Omac wont do au assay on the BS due to possible high grade and fear of contamination; that has to be sent to their HQ, Alex Stewart Int. in England. My field work on the BS and smelting out shows a lot of micron au occluded. We have high magnetite and hematite, low suphides, but the oxides present sure do encapsulate this micron material. The volumes of BS run at about 3KG per ton of gravel, so will mount up in time. Am thinking of sending off to specialist refinery who can process more efficiently and effectively - but again that is in the future, as is the idea of spirals after the Knelson for the economic values tailed off.

I am always looking at variations on the theme and not necessarily trying to invent the wheel. Most have been time proven.

The maps will be handy if possible and have mailed accordingly.

I don't think Guinea is a good idea as a back door, certainly not at present - could well be a fire. I sometimes go to Labe in Guinea from the farm. It is a six hour drive to that part of Guinea from that part of SL. It is highland country and great Fulani cattle to buy. up to 18 hands at the withers and 6 feet point to point horns - good breeding, and great meat.

Liberia is not much of an option either. Down to the coast and off - BUT that is Negative thinking

Look forward to Maps and let me know about the possible diamondiferous areas.

The BS problem sounds similar to here, except for the high ilmenite content, here. I have never found anyplace that will process it and pay a reasonable amount... then there is shipping cost, as this is the nether part of the rump of Canada.

It may be the start of the Alaska Highway, but it is still isolated. We still had horses and Bennett Buggies, when I was little, and the rest of the world had trucks and cars! The last horse usage, here, was in the late 50s.

One mining report I have, from the 50s, describes the claims as: *being at the end of a 75 mile Jeep trail, from Fort St.James!* Now the area is full of excellent, gravel logging roads and it is still about 50 miles, though. Grin

That is not typical now, but some roads have been abandonned, due to being logged out.

I will do up the maps, later tonight... I have a pretty good image program, old but grafted into my XP, from Win3.1, because I like it so much! Kiss

Yep,

The BS are trying and assuming they have value can be problematic to recover. An upgrade table is ideal if you have the quantity, RP4, Gemini, micron wave table and 1000-S are just some options. Even the cons from a Knelson need to be upgraded for a bullion standard. Smelting needs a good quantity of au in the BS and then the appropriate flux to oxidise is a fiery mix. Table good for the au and pgm's though. What are others thoughts. btw, there is a video on you tube of a clean up operation in Alaska, search Goldman Engineering Gold recovery.

I'd go but I have small children and would like to live long enough to see them produce grandchildren. Get back with me in 20 years or so, but only if you will supply AK's and PKM's for the group and training for those that don't know how to use them. Sorry for the sarcasm, but I've seen enough of what that area of Africa does not only to foreigners, but their own people as well.

Some 25 years back, I lived in Houston for a while; lived in Spring, flew out of Hooks. It was in one of the suburbs at a gas station, I saw my first toilet seat chained to the floor. Now, that was a rough neighborhood ! As a child, on our farm in Kenya I saw worse atrocities during the Mau Mau uprising of the late 50's. There are lighter tools for security than those you mention

Mau mau was indeed seriously ugly stuff and probably much worse than Sierra Leone!
