Excerpt Below:

One fact which is becoming increasingly clear concerns the spatial distribution of bronze objects in eastern Nigeria. Afikpo oral tradition claims that there exists a dump of bronze/brass/copper objects in the Ogwugwu valley. The spot is very sacred to the people and my attempts at locating the exact place did not get the necessary support from the local population. The bronze objects purport to have been abandoned by the Ego (the putative ancestors of present-day Ugwuagu and Amizu communities in Afikpo). In addition, the burial of a one-time chief, Okorie Chukwu, of Uzuakoli in Imo State is claimed by the elders to contain numerous burial goods including some bronze/brass objects. This site was brought to our notice by the incessant letters of one Mr. Akwani who asserted that there exist some royal tombs in Uzuakoli which might yield valuable archaeological information. After the usual survey and consultations, we were ready to test-excavate one of the chambers. But to our surprise, an explosive politicking ensued immediately and we were forced to abandon the investigation. There are, however, many garbage dumps and mounds which hold plenty of promise for archaeological investigation in Uzuakoli.

The Igbo-ukwu find (which was found by accident by the way), took the world by storm and retains it's title today as Nigeria's oldest discovered bronze-casting culture.

However, the excerpt above is stating that there are several more ancient Igbo-Ukwu -like sites across the Igbo Heartland of unknown number, with probably even more bountiful treasures. The only barrier to accessing them is politicking and maybe some local tussles.

It would be very exciting to see what is uncovered when Igbos get to excavating these sites.

People don’t really understand the meaning of Ndi-Igbo. It means NDI GBOO. Ancient people.
