An iron bangle (SF 09-132) made from a flattened iron rod with overlapping ends. One end of the bangle is bent inward. The bangle occurred as an isolated find in the upper levels of an area (mound 6) that archaeologists interpret as a metallurgical workshop. The bangle has been corroded by rusting. Scale in cm. Width: 7.9 cm. Weight: 25.6 g. Site Ngre Kataa. 6 June 2009.
Insitu pottery and iron artifacts associated with clusters B and C of what archaeologists interpret as a shrine that capped stratified deposits in a metallurgical workshop. Cluster B encompassed the objects on the south (right) side of the photo, west of (below) the tree stump. To the right of the black-and-white photo stick (lower right) is an iron spike (SF 09-174), a half bangle (SF 09-173) and a slightly curved iron disc (SF 09-172) in a carefully placed composition. Immediately to the east (above in the photo), an aglomeration of pottery sherds is stacked. Later excavation revealed a pedestal-handled pottery lid, dog skull and jaw bones carefully placed below these sherds in cluster B. Cluster C encompassed the artifacts to the north (left) of the tree stump. These included a series of pottery lids, portions of single pottery jar and sherds from other pots. An iron bangle (SF 09-148) is visible above and slightly left of the top photo scale, sitting adjacent to a pottery lid (NK 09-381) lying with its interior surface up. This wider shrine assemblage overlaid burned features associated with metalworking activities. Black-and-white photo scale in 5 cm increments. Arrows pointing north. Site Ngre Kataa. 10 June 2009.
A curved, tanged iron blade (brɔfiɛn in Nafaanra), slightly shouldered at the base (right), with a short narrow tang for the purpose of hafting to a wood handle. The tool shows signs of corrosion. The artfiact was excavated from a house mound. Scale in cm. Length: 19.1 cm. Weight: 54.7 g. Ngre Kataa, 4 June, 2009.
Miniature iron shackles (manacles). The artifact was excavated from a context that archaeologists interpret as a shrine located in metallurgical workshop. The shrine included many pottery jars and lids, iron bangles and other objects. The miniature shackles were placed inside a pottery jar, which was found lying on its side and broken. The shackles have been corroded by rust. Scale in cm. Width: 7.4 cm. Weight: 16.1 g. Site Ngre Kataa. 9-10 June, 2009.
Iron projectile point, the head of which (left) has a rounded base. Two small barbs project from the point's long tang. To make an arrow (snini in Nafaanra), the tang was inserted into a straight shaft made of bamboo, reed or lightweight wood to which it was hafted. This artifact was found in an area that archaeologists interpret as a metallurgical workshop, in the vicintiy of anvil and grinding stones and features interpreted as forges. The projectile point shows signs of corrosion by rusting. Scale in cm. Length: 15.2 cm. Weight: 16 g. Site Ngre Kataa. 4 June, 2009.

Iron projectile point. The head (left) is asymmetrical, perhaps the result of its base being broken. The intact side of the base is shouldered. Two small barbs protrude from opposite sides of the point's long tang (right). To make an arrow, the tang would have been inserted into a shaft made of bamboo, reed or lightweight wood. This point was found in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The artifact has been corroded by rusting. Scale in cm. Length: 10.1 cm. Weight: 8.9 g. Site Ngre Kataa. 4 June, 2009.
Asymmetrical barbed iron projectile point with a bent shaft. This artifact was found in an area that archaeologists interpret as a metallurgical workshop.

Tanged iron blade with pointed tip (left) and rounded shoulders. Two large concretions adhere to the blade's corroded surface. The tang (right) would have allowed the blade to be hafted to a wooden or bamboo shaft or handle. If hafted to a long shaft, it may have been used as a spear (chombo in Nafaanra). This artifact was found closely associated with a copper alloy twinned figurine, an iron bangle, a rounded quartz pebble and several other objects, which archaeologists interpret as a shrine cluster. The cluster was placed among metal-working features in a metallurgical workshop. Scale in cm. Length: 8.6 cm. Weight: 12.6 g. Site Ngre Kataa. 19 July 2008.

A piece of a copper alloy (brass) bar, found in association with burned features that archaeologists interpret as linked to metalworking (left: side view; right, end views). The bar is square in cross-section (right). One end appears finished and has a slight circular depression or dimple (bottom right). The other end (top right) is jagged and appears to be broken from a longer bar. The artifact was recovered from soil associated with an amorphous burned feature, underneath which were a series of burned basins likely created by forging activities. The object is similar in appearance to brass bars known from the Ma'adin Ijafen cache of brass ingots documented by Theodore Monod in eastern Mauritania in the 1960s. As such, this may be the form in which metalworkers got the copper alloys that were worked at the site. Length: 1.7 cm. Weight: 2.8 g. Scale in cm. Site Ngre Kataa. 25 June 2009.
A cluster of burned features is exposed in the northwest corner of excavation unit 50N 8W in an area interpreted by archaeologists as a metallurgical workshop (mound 6). Along the unit's west wall (left in photo) is an amorphous zone of fire-hardened red (Munsell color 2.5YR 3/6) matrix. A piece of brass bar (SF NK 09-293) was found in soil associated with this burned feature. Above and to the right (northeast), two circular burned features are visible in outline. These basin-shaped features had a thin lining of fire-hardened sediment, red to dark red (Munsell 2.5 YR 3/6 & 4/8) in color. The basins were filled with loose ashy sediment and small pieces of charcoal. A sample of burned matrix from feature 1 (top right basin) yielded a thermoluminescence (TL) age estimate of 1500 +/- 40 CE (Univ. Wash. 2455). Further excavation revealed additional basin-shaped features beneath the amorphous burned feature. The excavation unit's northwest corner peg is visible, upper left. View looking north. Site Ngre Kataa. 27 June 2009.
A cluster of burned basin-shaped features is exposed in the northwest corner of unit 50N 8W in an area interpreted by archaeologists as a metallurgical workshop (mound 6). The basins comprised a thin layer of fire-hardened sediment, red to dark red (Munsell colors 2.5 YR 3/6 & 4/8) in color. Basin features 1 (top right) and 2 (left of feature 1) measured about 8-9 cm deep and were filled with ashy soil. Basin feature 5 (far left) was shallower. Its fire-hardened surface showed a pinkish tinge. Samples of burned basin matrix from features 1 and 5 yielded thermoluminescence (TL) age estimates of 1500 +/- 40 CE (feature 1; Univ. Wash. 2455) and 1580 +/- 40 CE (feature 5; Univ. Wash. 2456). Photo bar marked in 5 cm increments. Arrows pointing north. Site Ngre Kataa. 29 June 2009.
A boulder used as an anvil stone (GS 09-07) sits insitu in an excavated area interpreted as a metallurgical workshop. A black-and-white photo scale stick stands vertically against it. The boulder's upper surface shows signs of use wear and its north-facing side is marked by a cup-shaped depression that resulted from repeated use. To the north (left), a fist-sized hammer stone (GS 09-09) rests insitu on a pedestal of soil left in place as the unit was excavated. Two stones showing evidence of use as grinding stones sit nearby, a north arrow placed by one(GS 09-10; center photo) and one in the southwest corner of the excavation unit (GS 09-08; bottom right). Another insitu anvil stone (GS 09-6) sits in the northeast corner of an adjacent excavation unit (48N 0W; top right of photo). The narrow band of loose soil angled across the southwest corner of the excavation was created by a burrowing animal. Photo stick and small arrow scale in 5 cm intervals. Photo scale arrows pointing north. Site Ngre Kataa. 2 June 2009.
A boulder used as an anvil stone (GS 09-01) sits insitu in an excavated area interpreted as a metallurgical workshop. This was one of several boulders associated with burned features and other residues of metalworking. The boulder's upper surface showed signs of use wear and its south-facing side is marked by a deep cup-shaped depression that resulted from repeated use. A burned feature interpreted as the remains of a forge is visible behind the anvil stone (upper left) in the northwest corner of excavation unit 50N 2W. Flat photo scale in cm. Arrow pointing north.
