In Sierra Leone Ayiko has three sites of stone-granite quarrying and one site for sand extraction. The sites are located in the areas of Freetown (the capital city of Sierra Leone) and in the area of Port Loko and Mekani.
One of the stone quarrying sites, namely Mapathe, near the city of Port Loko in the west of the country, is supplying currently the new construction work of the international airport of Freetown. The other sites supply commercially the vast needs of the infrastructure developments and road building in the west and middle of the country.
The work on the sand extraction site which is located in the south perimeter of the city of Freetown has been organized and licensed and planned to commence commercially in 2011.
