Douala Basin Heavy Mineral Sands (HMS) Project.

A Strategic, Port-Proximal Heavy Mineral Sands Opportunity

A 2,580km² project within 50km of a deep-water port, with significant historical drill intercepts.

The Douala Basin project provides a strategic, second-front opportunity located on Cameroon’s coast within 50km of key port infrastructure. The coastal sedimentary basin is known to host significant mineral sands.

 
The project includes the former “Missole Project,” which was held by French multinational Eramet. Historical sonic drilling by Eramet returned significant intercepts.

Location:
Within 50km of the deep-water port of Douala
Commodity:
Heavy Mineral Sands (HMS)
Project Size:
2,580 km²
Ownership:
Granted and Under Valid Application.

Geology

Geologically the Douala Basin is a coastal sedimentary basin consisting of a package of mainly marine sedimentary formations of Cretaceous to Quaternary in age. Thick, preserved sequences of sandy material are known to exist across the tenement package and these are thought to represent palaeo-placer coastline dune deposits. These sedimentary environments are prospective for classic aeolian placer HMS deposits which normally host accumulations of valuable heavy minerals such as ilmenite, zircon, rutile and monazite. 

History:

The Diwong licence was previously known as the Missole Project was held by the French multinational Eramet. Eramet drilled some 60 sonic holes on the Project for 1,080m (582 samples) with 39 hand auger holes for 190m (39 samples) specially targeting rutile and zircon. The drilling intersected thick sequences of sands and confirmed the presence of rutile and zircon within the valuable heavy mineral assemblage (Table 1).

Eramet discontinued the Project when it exited Cameroon in 2023 primarily due to the unsuitable setting of the mineralisation within its core Central Cameroon project Akonalinga (which targeted alluvial placer rutile deposits within the lower lying river systems).

Historical Sonic Drilling at Douala by Eramet:

  • 010m @ 5.0% THM from surface (DIB_S00024)

  • 012m @ 4.7% THM from surface (DIB_S00018)

  • 07.7m @ 4.0% THM from surface (DIB_S00022)

  • 018m @ 3.7% THM from surface, ending in mineralisation (DIB_S00010)
