Kimberlite is one of the most important host rocks of diamond. This does not mean that every single Kimberlite you find contains diamonds.
While most of the Kimberlite found in the country has diamonds, Sierra Leone’s geoscientists have said exploring Kimberlite in the country is difficult and therefore the government need to develop geophysical baseline information on Kimberlite.
Geo Salim Sillah, Chief Geologist, AMR Gold, said, “Kimberlite exploration is difficult in Sierra Leone because discovering Kimberlite is mostly related to indicator Kimberlite. Like other rocks, there are specific minerals that are associated with Kimberlite and when one sees those minerals he knows that Kimberlite was present. However, because Sierra Leone is a tropical environment and because Kimberlite highly contains minerals that are susceptible to weathering people who come to do exploration normally return to their countries stating that there was no Kimberlite.”
“It does not mean there is no Kimberlite probably they are highly weathered or you are looking for the wrong mineral”.
Sillah added that finding Kimberlite would boost the country’s economy. “Normally the lifetime of Kimberlite mine is over 20 years. Even though most of the Kimberlite you are likely to find in the country will be smaller, that does not mean there wouldn’t be bigger Kimberlite bodies sitting somewhere. But at least regardless of the size, if they are mining Kimberlite your mine life will be approximately between 10 and 20 years”.
On Friday 28 April, the Sierra Leone Institution of Geoscientists (SLIG), during their monthly general meeting at the Ministry of Mines and Mineral Resources, discussed “Indicator Mineral Dispersion around a Kimberlite pipe in Gulbarga District, Karnataka, India”.
Sillah said the discussion “is pertinent to our exploration here in the country because Sierra Leone is endowed with Kimberlite. Although we see very few have been discovered, there are many more that haven’t been discovered yet. So it is good for young geo scientists to learn how to look for them”.
Mike Lynn, Executive Officer of Allotropes Diamonds, was the Guest Speaker. He said, “In Sierra Leone, they were using the magnetic and sampling methods which are similar to what they do in India. The key issue for Kimberlite exploration cannot be the same for other commodities. In terms of Kimberlite exploration, you need to be out to preserve those magnesium clays”. However, “the weathering profile here is so extreme”.
He added that there are some limitations to Kimberlite exploration in the country. “Active erosion is non-existent in the area where we are working at the moment, because it is non-existent, they are not liberating fresh indicator mineral into the secondary environment and that makes indicator mineral sampling particularly difficult”.
Also, “the mine craton is deeply eroded. The Kimberlite part preservation is quite poor but the saving grace for sierra Leone is that the crates is so spectacular and the diamond qualities are so spectacular so you do not need to have such a big Kimberlite to be of economic interest”.
Sillah suggested that the government should to come in and provide geophysical baseline survey information to companies who come into the country to do Kimberlite exploration. That, he said, will provide them with knowledge about the potential of Kimberlite in the licenses they were applying for.

#NOTE: if most of the kimberlite found have diamonds, why is Sierra Leone still struggling to provide the basic needs of it inhabitants?# "Papa God help Dis Country now"

Breaking news: 706 carat diamond found in kono district

A pastor has unearthed a massive gem in eastern Sierra Leone.

Pastor Emmanuel Momoh, who also works as a miner, discovered the 706-carat diamond in Kono district, the government said in a statement.
He handed it over to President Ernest Bai Koroma, who thanked him for not smuggling it out of the country. The President pledged to reward him with some of the proceeds from the sale of the diamond.
The government plans to sell it to the highest bidder, the President said.
The gem may not be the largest ever found, but it's pretty close.
Last year, an uncut 1,109-carat diamond was auctioned in London -- the largest uncut diamond ever found.
