Orapa found by accident. Story goes a Sales rep parked up outside an isolated concession type store far out in the bush. Went in to buy a coke and then sat against his car to drink it. His eyes happened to spot a curious glass like stone which had a particular symmetrical shape. So he picked it up and the rest is history.
Story going round also that Lord Luken was holed up in one of the Tuli Block Farms. Interesting place Botswana.
Our patch of land is over covered by a hard iron pan type layer of hard surface material which has kept the Cu deposits hidden for decades. Could it be more than just copper is hidden. Why do MOD think it is worth a mention ??
Agree our resident Geologist. Diamonds have a deep seated origin and are formed in an environment of high pressure and temperature. The pipe like structure derives from fluid mobility and relative gravitational influences within the Cratonic setting. The mineral suite almost by definition will have Mafic and Ultra Mafic minerals with garnet being essential. ......... to give a Kimberlite pipe. They tend not to be surrounded by unaltered sedimentary rock. Hot emplacements into sediments produces altered rock which might be described as metamorphic. Take these down to depth where it is hot and high pressure and they can progress into igneous rock.
One for Bonker99 Why are they (MOD) making enquiries to Japanese, Korean, and Chinese smelters wrt to High quality (As free) concentrates.
Does that mean we wont be building a smelter in Botswana so limiting the value added in Botswana ?? Also a big relief on our costs but less value for our product and quick turn around. Concentration from open cast is easy peezzy and cheep so quick to production and revenue.
Why did they poke a hole down the deep side limb of the dome they have decided to drill first. ....... I wonder. ??? Ok they picked up the marker horizons but did this pick up the thickest mineral rich layers. ..... still wondering ????
MMs got this well under control;
