Timna Copper Mines

Overview

The Timna Valley in the southern Arabah holds thousands of ancient mine shafts and several large smelting camps. Nelson Glueck surveyed it in 1934. Beno Rothenberg's Arabah Expedition surveyed from 1959 and in 1969 excavated a shrine of the Egyptian goddess Hathor (Site 200); from that find the main mining and smelting was assigned to the Egyptian New Kingdom (the 'Egyptian paradigm').

Since 2012 the Central Timna Valley Project of Tel Aviv University, directed by Erez Ben-Yosef, has re-excavated the smelting camps with radiocarbon dating of short-lived seeds. Site 30 is now dated to the early Iron Age (11th-9th century BCE) (Ben-Yosef et al. 2012). At Site 34, the 'Slaves' Hill', a 1 m section through Slag Mound 19 contains 32 layers representing about 150 years of smelting, and eleven AMS dates from it fall in the 10th century BCE. Extraordinary dryness preserved seeds, textiles (wool, goat hair and linen), rope and cordage.

OSL dating of mine fills showed open-pit mining at Merkavot 1 in the Chalcolithic and again at the end of the 2nd millennium BCE, and a shaft at Merkavot 2 in the Chalcolithic-Early Bronze Age, overturning the assumption that simpler mining techniques are always older. The Iron Age industry relied on local white broom and acacia charcoal, and its end has been linked to fuel exhaustion. The Hebrew Bible never names Timna; the tie to Solomon is a modern label.

What the evidence shows

• Site 30 radiocarbon-dated to the early Iron Age, 11th-9th century BCE, replacing the Late Bronze/New Kingdom date (Ben-Yosef et al. 2012, as summarized by the CTV Project).
• Site 34, Slag Mound 19, Square 19A: deposit slightly over 1 m thick, 32 layers, c. 150 years of operation; eleven AMS radiocarbon dates on short-lived seeds, all 10th century BCE (CTV 2013 season report).
• The slag's high copper content and a two-piece tuyere at Site 34 fit Late Bronze / early Iron Age smelting technology (CTV 2013 season report).
• The Hathor shrine (Site 200) was excavated by the Arabah Expedition in 1969; on that basis Type C shaft-and-gallery mines (cut with metal chisels) were dated to the Egyptian New Kingdom (CTV mines page).
• OSL: Merkavot 1 Area A open-pit mine is Chalcolithic; Merkavot 1 Area B was mined at the end of the 2nd millennium BCE; the Merkavot 2 Area C shaft is Chalcolithic-Early Bronze Age (CTV mines page).
• Late Bronze Age copper production is also attested at Site 3 (Yagel, Ben-Yosef and Craddock, Levant 48, 2016).
• About 100 textile and cordage fragments from the 2013-2014 seasons at Site 34: wool, goat hair and linen, some with coloured designs (CTV textile page).
• Charcoal from two stratified waste heaps of the 11th-9th century industry is mostly local white broom (Retama raetam) and acacia; later layers include less suitable taxa, read by the authors as a widening search for fuel (Cavanagh, Ben-Yosef and Langgut 2022).
• In Timna the smelting ores were almost exclusively the Amir/Avrona type in the Late Bronze-Early Iron cycle (Bode et al. 2024).
• Heavy-metal enrichment of soil at two Timna smelting camps is confined to the production areas (Yagel et al. 2024).

Open questions

• Who ran the Iron Age industry? Ben-Yosef (Vetus Testamentum 69, 2019) argues that a complex society of largely nomadic people ran the Arabah copper centers, and that archaeologists of all schools have missed such polities because they rely on stone architecture ('architectural bias'). Eshel et al. (PLoS One 2025) call it 'the Arabah copper polity' and propose Faynan and Timna were 'possibly controlled by a joint polity'. Whether this polity is biblical Edom, a Judahite/Israelite enterprise, or something else is not settled by any inscription from the sites; it is an inference from location (1 Kings 9:26 places Ezion-geber 'in the land of Edom') and date.
• Egyptian or local? Rothenberg's Arabah Expedition dated the main mining and smelting to the Egyptian New Kingdom from the Hathor shrine (Site 200). Ben-Yosef et al. (BASOR 367, 2012) show from radiocarbon that the largest camps (Site 30, Site 34) operated in the 11th-9th centuries BCE, after Egyptian control of Canaan ended. Both phases are real; the dispute is over which phase the thousands of shafts belong to, which the CTV Project calls 'now insecure'.
• Link to Solomon. The radiocarbon peak at Site 34 overlaps the 10th century BCE that the biblical chronology gives Solomon. No object, inscription or trade record found at Timna links its copper to Jerusalem; 1 Kings 7:46 places the casting of the temple bronze in the Jordan plain, not the Arabah.

Since 2024

• 2024-02Bode et al. (METALLA 27) publish lead- and copper-isotope fingerprints for Early Iron Age Timna and Faynan copper: Timna used almost only Amir/Avrona ore. [7]
• 2024Yagel et al. (Scientific Reports) map soil heavy metals at two Timna smelting camps: pollution confined to work areas; organization of production changed between the Early Bronze and Iron Ages. [6]
• 2025Eshel et al. (PLoS One) trace Iron I bronze at el-Ahwat in the central hill country partly to Timna ores, and argue for a joint Arabah copper polity supplying Faynan and Timna copper inland. [8]
• 2025The CTV Project lists a 2025 field season on its website. [1]
• 2026Langford et al. (Journal of Arid Environments 233) document 14 isolated copper-mining sites across the Araba outside the main hubs. [9]
