Resources become value through work.

Thor reports gold production at Segilola in Osun. This is an operating-mine example, distinct from a mineral prospect. The point uses nearby Ìpèrindó for orientation; it is not the pit location.

Limestone quarrying supplies cement manufacture here. Lafarge identifies its limestone mine in its sustainability reporting and documents a quarry visit in 2025.

Researchers analysed limestone samples from quarry sections of the Ewekoro Formation at Shagamu. This locality connects sedimentary geology with the cement industry; the pin identifies the town rather than a quarry perimeter.

A geophysical study investigates structures associated with marble, gabbro and muscovite in the Igbeti–Moro area. The town anchor represents a wider study area, not the extent or economic value of any deposit.

Studies describe rare-metal mineralisation and industrial minerals in Ijero-area pegmatites. A lithium-bearing mineral occurrence does not establish a battery-grade reserve or a commercially viable extraction project.

Airborne magnetic and radiometric interpretation examines rare-earth and gemstone mineralisation in the Ijero–Aramoko pegmatite field. It identifies geological exploration relationships, not a proved reserve for the whole area.

Geochemical work identifies quartz and microcline among the major minerals in sampled Emure pegmatites. Industrial suitability needs material testing; a mineral’s presence alone does not establish a workable deposit.

Researchers sampled kaolin mining fields in Ilorin South and Ilorin West, including environmental radioactivity measurements. This entry documents studied extraction localities, with the city as an orientation anchor; it is not a current mine-status survey.

Electrical-resistivity surveys mapped shallow bitumen-saturated layers around Agbabu. The study also examines groundwater vulnerability where protective clay is discontinuous. This is evidence of mineralisation, not a claim that a commercial mine is operating.

The ministry identifies limestone and reports exploitation at Onigbolo. The inventory is undated; present operator and output need separate verification.

The ministry records kaolin affected by iron oxides at Kétou. Material quality matters for its possible ceramic uses.

White kaolin is listed at Adakplamé. This is a locality reference, not a current reserve estimate or mine boundary.

The ministry identifies silica sands at Sèmè with potential glass uses. The settlement point represents the wider locality.

The ministry describes Manigri granite among Pan-African post-orogenic intrusions and its ornamental-stone potential. The map uses the settlement anchor; it does not identify a working quarry.

The official inventory lists a columbite–tantalite occurrence at Kilibo. An occurrence is an exploration lead, not proof of a mineable reserve.

Toui appears among central Benin’s listed columbite–tantalite occurrences. The entry carries no verified current tonnage or production claim.

The JICA regional study lists green granite at Ezimé as an ornamental-stone locality. Shown as neighbouring regional context, not as an exclusively Yorùbá deposit.

The JICA study discusses Gnaoulou among historically worked marble localities. It does not establish current production. Shown as neighbouring regional context, not as an exclusively Yorùbá deposit.

The JICA study lists differently coloured granites at Glito in eastern Mono. Shown as neighbouring regional context, not as an exclusively Yorùbá deposit.

Pagala appears in the JICA study as a historically worked marble locality. No current operating claim is made here. Shown as neighbouring regional context, not as an exclusively Yorùbá deposit.

Kwara lists these minerals for Irepodun, which includes Oró, Esie, Agbamu and Omu-Aran. This is district-level evidence, not confirmation that each mineral occurs at the Oró marker. No deposit tonnage is verified here.

The Ilorin Sheet 223 paper mentions aquamarine reports around Oro. Its introduction explicitly describes such local mineral reports as not documented. This entry is an exploration lead, not a confirmed aquamarine deposit or reserve.

The same regional paper mentions reported talc around Agbamu while noting that local mineral reports were not documented. The geophysical investigation motivates further ground verification; it does not certify a mineable talc reserve.

Regional research mentions local reports of aquamarine, gold and tourmaline around Odo-Eku. These introductory reports are explicitly described as not documented; distinguish them from sampling-confirmed deposits.

The state inventory lists these minerals across Isin, whose towns include Edidi and Isanlu-Isin. It gives no deposit coordinates. The Owu-Isin headquarters anchor represents the district, not a mine at the town.

Sample testing examines marble mineralogy, chemistry and physical properties at Oreke and Owa-Kajola. Suitability varies between samples and end uses; the study supports a material assessment rather than a current reserve or production figure.

Research tests marble from the Owa-Kajola and Oreke areas for construction and industrial applications. Strength and composition matter: one locality name does not imply uniform stone quality throughout the area.

Geological and geochemical work describes tantalite mineralisation in Egbe-area pegmatites. This adds the Yagba / Okun part of the regional picture. No current reserve tonnage or production claim is inferred.

Heavy-mineral and stream-sediment prospecting investigated gold north of Isanlu. This is Isanlu in the Yagba area, not Isanlu-Isin in Kwara. The town anchors the study region; the historical study is not evidence of a current commercial mine.

Ororo lies offshore Ondo in the western Niger Delta petroleum system. The operator’s historical report describes oil and gas-condensate tests. It reports contingent resources, not proved reserves. Current production and recoverable volumes are not established by this entry. The square marks Igbokoda on land solely for orientation.

Local geology supports granitoids at Omu-Aran; no deposit tonnage, quarry title or Oro reserve confirmed.

Large limestone deposits at these exact towns are unverified. Do not confuse Oro town with River Oro/Oro Forest Reserve or the Kajola–Oreke marble corridor.

Statewide clay occurrence is supported; the two specified deposits and abundance need site investigation.

Kwara records kaolin occurrences; no verified Esie reserve or stated commercial scale in the sources reviewed.

Omu-Aran’s quartzite and quartz-mica schist are documented; no electronics-grade deposit or moderate reserve established.

Esie soapstone has local geological support; the “moderate deposit” and product-grade claims are unquantified.

Idofian XRD identifies feldspar-group minerals. Presence in sediment/rock is not proof of a workable feldspar deposit.

Kwara mapping records mica, but Esie-specific quantity and current mining ownership are unverified.

Kwara-wide gemstone listings do not substantiate each town or a moderate reserve.

No substantiated Oba-Isin phosphate deposit or quantity located in the available sources.

Bauxite deposits at the named localities and their potential scale remain unverified; no reserve evidence has been established.

No substantiated Omu-Aran gypsum deposit/quantity found in the available sources.

A possibility is not a deposit or reserve; these exact town-level claims remain unverified.

Kwara gold occurrence elsewhere is documented; it does not corroborate these towns or the estimated scale.

The named locations remain unverified. A 2018 scholarly inventory instead records tourmaline at Dogondaji Oro; current activity must be checked afresh.

Provenance research links the sculptures to local talc-bearing rock. This confirms a geological relationship, not a commercial reserve or permission to quarry a heritage site.

Field research describes these rocks in the local geological setting. Industrial grades, deposit tonnage and extraction rights are not established.

X-ray diffraction in the sediment study identifies these mineral components. Sediment composition does not establish a workable mine deposit.

A field study sampled a kaolin mining area here. The research documents the locality and examines radiological hazards; it does not certify every product grade or present operating status.

OgunInvest lists these materials as investment sectors. This confirms an official state-level listing; individual sites, quality, reserves and feasibility require separate evidence.

These materials appear in the NGSA state mapping. The regional reference does not place a deposit in every town or establish grade and recoverable quantity.

RMRDC identifies these materials in its state technical brief. Bauxitic clay is not an audited bauxite reserve; town-specific sites and processing suitability need investigation.

NGSA maps these sedimentary formations. This is geological context, not a permit to dredge or evidence of industrial silica purity.

The programme identifies this material and locality for development. Current output, project completion and certified reserves are not established.
