"Mindouli is a regional center on Route Nationale 1 (RN1) and the Pointe Noire-Brazzaville railway.

The copper occurrences crop out over a distance of about 3 km along a limestone escarpment behind the town. They were mined by the French between 1948 and 1960.

"… The copper mineralization was mined in a number of open cuts and via several shafts and declines, now collapsed. The largest open pit was called the Sanda carrière (quarry) according to my sources. A Chinese company currently has exploration rights over the Mindouli and M'passa occurrences. They have driven several adits into the mineralization along the line of old workings and collected several thousand tonnes of metallurgical samples. Mostly massive chalcocite, malachite, cuprite mineralization. I saw practically no dioptase on dumps from these workings." (Dr. Demetrius Pohl, http://www.mindat.org/mesg-6-234115.html)
