Where in Venezuela are lithium, coltan, and rare earth elements currently mined or reported?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Geological surveys and recent reporting locate most confirmed and reported coltan and rare earth occurrences in Venezuela’s southern Guayana/Orinoco region—especially Bolívar and adjoining Amazonas—largely inside the state-decreed Orinoco Mining Arc (OMA) [1] [2] [3]. Lithium is not a mature, large-scale Venezuelan industry in current reporting; statements about lithium in Venezuela are speculative or describe preliminary investigations rather than active commercial mines [4] [5].
1. Southern Venezuela as the epicentre: Bolívar, Amazonas and the Orinoco Mining Arc
Multiple investigative and policy sources place the active and reported deposits for coltan, cassiterite (tin) and rare earth elements in the Guayana Shield and the Orinoco Mining Arc — a 111,843 km² zone that Caracas designated for mineral development in 2016 — with Bolívar state repeatedly named as a primary locus [1] [2] [3]. Reporting by The Guardian, CSIS and ICIJ map the flows and the sites to jungle river corridors and frontier plateaus along the Colombia–Venezuela border and deep inside Bolívar and Amazonas [2] [6] [7].
2. Coltan: confirmed presence, mostly illegal or informal extraction
Coltan’s presence in Venezuela has been publicly acknowledged since 2009 and the government later announced a coltan concentration plant and exports, but the lion’s share of coltan activity described in reporting is informal or illicit and centred in southern Bolívar and border zones [8] [9] [10]. Investigations by ICIJ, InsightCrime and others describe illegal mines, smuggling corridors into Colombia and the Caribbean, and paramilitary/criminal control of extraction points in the borderlands [11] [10] [7].
3. Rare earth elements: known geological occurrences, limited formal exploitation
Scientific and trade-analytics sources identify REE mineralization in Venezuela’s Guayana Shield — Cerro Impacto (Bolívar) is a documented carbonatite with REE enrichment — and sedimentary contexts (e.g., Navay phosphorites) show REE potential, yet reporting stresses that formal exploration and production remain limited and unevenly documented [12] [13] [5]. Recent media and NGO reporting say miners are now targeting REEs alongside coltan in the same southern zones, but evidence points to largely informal, environmentally destructive operations rather than regulated, commercial REE mines [3] [14].
4. Lithium: presence speculative, not a developed Venezuelan mining front
Analyses of Venezuela’s critical-minerals potential mention lithium among a long list of strategic elements, and some outlets note preliminary investigations or “possible presence” in salt-flat-like contexts, but there is no robust documentation of large-scale lithium mines in Venezuela comparable to the Lithium Triangle in Argentina, Bolivia and Chile [4] [5]. Policy briefings and databases list lithium as a potential opportunity for diversification, not as an established production centre [15] [4].
5. Who controls the ground and the supply chain: state, criminal groups, and shadow markets
Multiple sources report that instead of multinational concessions, the OMA and southern mining zones have become dominated by criminal networks, guerrillas, and informal operators, with allegations of state complicity or at least uneven enforcement [6] [16] [3]. Investigations map export routes through Colombian territory and Caribbean ports; legal exports have occurred (a 2018 documented coltan shipment), but sanctions and seizures have curtailed transparent trade [11] [9].
6. Environmental and human-rights imprint: deforestation, mercury and violence
Satellite studies and field reporting link the new rush for coltan and REEs to rapid deforestation, river contamination (mercury and sediments), and human-rights abuses affecting Indigenous and frontier communities in the Orinoco/Guayana region [17] [14] [18]. CSIS and other analysts frame the crisis as one of “illegal, destructive mining” that amplifies insecurity and undercuts legitimate development [19] [17].
7. Limits of current reporting and where evidence is thin
Open-source and journalistic reporting provide strong localization for coltan and REE activity in Bolívar/Amazonas/Orinoco Arc; however, comprehensive, publicly releasable geological quantification (reserves, grades) and verified maps of lithium occurrences in Venezuela are not present in the supplied materials — lithium claims remain preliminary in available sources [5] [4]. Large-scale, state‑run lithium projects like those in Argentina/Chile are not documented for Venezuela in the current file set [20] [21].
8. What to watch next: indicators of formalisation or expansion
Watch for verified geological surveys, government tender documents or foreign-investment agreements that specifically name sites (e.g., Cerro Impacto, Parguaza region, specific salares), export permits or trade records, and satellite-deforestation monitoring for new clearings in Bolívar and Amazonas. If formal exploration licenses or metallurgical facilities for REEs or lithium appear in official records, that would mark a shift from informal extraction to commercial development — none of which is robustly documented in the current reporting [12] [9] [5].
Sources cited above document the locations and patterns described: Orinoco Mining Arc and Bolívar/Amazonas as the principal areas for coltan and REE activity [1] [2] [3], documented coltan operations and seizures [11] [9], scientific records of Cerro Impacto and other REE deposits [12] [13], and preliminary notes on lithium’s speculative status in Venezuela [4] [5]. Available sources do not mention detailed, large-scale lithium mining operations comparable to the Lithium Triangle (not found in current reporting).
