The ISL technology in uranium extraction is relatively new compared to conventional uranium mining in the World.
Dear Mr. Kileo,
I cannot give an answer meeting the regional aspects of your question but can only refer to one of the sites of uranium ISL that has been looked at from different angles and studied very well under the header E&E (economic geology and environmental geology). It is the underground U mine Königsstein near Dresden in eastern Germany. It is a typical sandstone-hosted low grade U deposit of Cretaceous age, a type which has been mined on both sides of the Czech (Hamr)/German border (Königsstein). There are numerous papers available on the applied and genetic economic geology as well as the measures taken for the rehabilitation of the mining area, particularly in terms of regional hydrogeology.
You can compare this type in parts with the U deposits hosted by sandstones in the neighboring Malawi of Paladins´s Kayelekera Uranium Mine. So you have a “missing link” between your country and the reference sites abroad Africa.
I wish you much success.

The only deposit where uranium is likely going to be extracted by ISL is Mtonya in Tanzania.
Dear Abdalah Kileo please have a look at the following useful overview issued by the International Atomic Energy Agency IAEA:
In Situ Leach Uranium Mining: An Overview of Operations
https://www-pub.iaea.org/MTCD/Publications/PDF/P1741_web.pdf
This report can be freely downloaded as pdf file from the internet. It was issued in the year 2016 and does not list an operating mining site in Africa.
