Good day.
Please be informed that we have cooperated with one Ukrainian company, which works long time in Burundi, Africa .
This company can provide to sell to your Buyers:

- tungsten concentrate (50-55%WO3),
- lithium ore (5-9% Li2O),
- Copper ore (20-35%Cu). 
All deliveries will be confirmed by an independent international laboratory Alex Stewart, SGS or another at shipment.
Delivery : FOB port Dar Es Salam. Maersk is responsible for Logistic to end Buyers in 20-feet containers.
Also they say that their company can source any commodity, which is in African continent upon our request. 
Interest in collaborating (We think to invite International Investors):

 Increase in production and exports
 Geographical expansion of the supply
 Purchase and upgrade accessories
 Putting into operation of new deposits
 Inclusion in the range of export of new products (Copper, Cobalt, Rare Earth)
 Amending existing license for the export of new products (ores and concentrates)

Additional information to our previous proposal about Ukrainian company, which is working in Africa very long time.

Nowadays the Owner has:
- Platinum - 5 kg,
- Silver - 1000 kg,
- Iridium, Rhodium, Niobium - 60 tons,
- Appatite - 40 tons,
- Lithium - 1 thousand tons,
- Cassiterite - 1 thousand tons with a tin content of 60%.
If there is interest, a certificate, verification and all procedures are done.
There is also gold in the sand. This may be of interest to your Buyer,
since the price is lower than the world price.
The Owner knows plenty connections and links and can source anything what Africa has. 
Please send us your good company introduction/Company Profile 
and your questions/comments/proposals/requests to us.
Have a nice day!
Thanks/Best Regards,
