Metal Detecting Laws in Guinea-Bissau

A general right to metal detect in Guinea-Bissau could not be confirmed. The captured laws describe land-use rights, protected-area restrictions and older rules for finds, but they do not establish a complete current hobby-detecting regime. Before planning a search, separate permission to enter, permission to search or dig, and any duties concerning what you find.

The rules, land by land

Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.

Ordinary detecting and archaeological searching

The older parliament-hosted Constituição da República da Guiné-Bissau (Constitution of the Republic of Guinea-Bissau), article 17(1), describes State preservation of cultural heritage. It supplies no detector permit, archaeological excavation procedure or finder reporting deadline. Its current constitutional status was not verified.

Tiniguena’s November 2025 account concerns a proposed cultural heritage decree-law. It does not establish an enacted permit system. A complete current rule for archaeological searching or excavation, and a separate rule for finding recently lost coins or jewelry, could not be confirmed.

The land legislation distinguishes geological-resource prospecting from land-use rights. That purpose-specific distinction does not settle searches for manufactured lost objects. No ordinary hobby permit issuer, application form, fee or duration was verified. Missing detector-specific wording is not permission to enter land, dig or remove a find.

Private land and local access

The Lei nº 5/98, de 23 de abril — Lei da Terra (Land Act) distinguishes State ownership of land from protected customary and concession-based private use rights. The Decreto nº 6/2018 — Regulamento Geral da Lei da Terra (General Land Act Regulations) implements those rights and distinguishes geological, forest, protected-area and coastal regimes. State ownership does not make occupied land freely searchable.

Resolve entry and the proposed search with the lawful land-use holder and relevant authorities. An access agreement does not settle heritage protections, protected-area rules or ownership of a discovery. The complete current conditions for ordinary detecting on privately used land remain unresolved.

Monuments, archaeological places and sacred sites

The Decreto-Lei nº 5-A/2011, de 1 de março — Lei-Quadro das Áreas Protegidas (Protected Areas Framework Act) includes natural monuments and sacred forests among protected-area categories. Those categories do not establish the complete regime for historic monuments or archaeological excavation. Current designations and site-specific searching rules were not comprehensively verified.

Article 34(3) of that framework separately makes access to sacred forests and sacred sites inside a park or another protected area subject to prior authorization from the communities connected to them. Community access authorization does not by itself settle permission to detect, dig or keep a find. This protected-area provision is not presented as a rule for every sacred place nationwide.

National parks and nature reserves

The captured Protected Areas Framework Act applies to classified terrestrial and marine areas. Under article 26, integral-preservation zones bar works, installations and other activities, with exceptions for public visits under internal rules; collection or fishing recognized by those rules exclusively for resident communities; conservation science or measures authorized by the IBAP director after consulting the area director; and works needed for those exceptions.

Article 27 limits access to strict-preservation and regeneration sectors to staff on duty, duly authorized scientific observers and resident communities. Article 28 requires authorization for potentially damaging activities in transition zones. Articles 29–33 provide separate conditions for activities, licenses and concessions in sustainable-development zones.

These distinctions matter when choosing where to go: visitor admission alone does not answer whether a search or target recovery is allowed. Individual classifications, management plans and internal rules were not comprehensively verified, so a general park detecting rule remains unresolved. The separate prior community authorization for sacred forests and sacred sites within protected areas also applies.

Beaches, islands and coastal land

Articles 68–79 of the General Land Act Regulations address mainland coastal and island land concessions. They distinguish coastal, island, tourism and protected-area regimes without establishing general public permission to detect on a beach.

Article 75(2) prohibits aggregate extraction in formally declared integral tourism-development zones and requires prior approval from the ministry responsible for tourism for urban development interventions there. This is not established as a universal rule for every beach or small target-recovery hole. Article 78 preserves protected-area and biosphere-reserve requirements.

Complete current zone designations, management plans and later planning instruments were not obtained. A beach’s access arrangements, any protected-area designation and the proposed recovery method need separate resolution; ordinary detector use and target digging on beaches remain unconfirmed.

Public forests

The Decreto-Lei nº 5/2011, de 22 de fevereiro — Lei Florestal (Forest Act) regulates forest resources and forest lands. Article 16 covers plant collection and other listed customary activities; it does not grant a right to search for metal objects. Article 33(g) provides for seasonal access prohibitions in specified forests or forest zones to prevent and fight fires.

Article 38 preserves community forest practices and rights only insofar as they are compatible with the Act and forest regulations. Protected-area controls can overlap. The Decreto nº 12/2022 — fim da moratória florestal (End of forest moratorium decree) ends the stated forest moratorium without supplying hobby-detecting permission.

Complete current forest regulations, access orders and ordinary detector rules were not verified. A customary collection right or the end of the moratorium should not be treated as permission for a visitor to search for and recover metal objects.

Lost property: an older code, with current limits

The captured Guiné-Bissau — Código Civil e Legislação Complementar (Civil Code and Supplementary Legislation) is a 2006 compilation hosted by the national prosecutor. Official news dated July 13, 2026 describes government approval of proposed Civil Code revisions. The resulting enacted text, if any, its commencement and any special heritage rules were not verified. The provisions below describe the captured older text, not a confirmed complete current finder regime.

Article 1323(1) of that text requires a finder to return an object to its known owner or notify that owner. If the owner is unknown, it requires an announcement in the most suitable way, considering the object’s value and local possibilities, or notification to the authorities, observing existing local customs. It does not name a particular authority or set a fixed reporting deadline.

Under article 1323(2), the finder acquires an unclaimed lost object one year after the announcement or notice. That period does not run simply from the day of discovery, and the provision does not give immediate title to an identifiable owner’s lost property. Because currentness remains unresolved, it is not a confirmed present-day entitlement to keep a find.

Hidden valuables, reporting and ownership

Article 1324(1) of the same captured 2006 compilation concerns qualifying hidden or buried valuables whose owner cannot be determined. It divides them equally between the finder and the owner of the movable or immovable thing containing them. This older ownership provision does not authorize a search or excavation.

Article 1324(2) requires announcement under article 1323(1) or notification to the authorities, except where it is evident that the treasure was hidden or buried more than 20 years ago. That exception does not establish exemption from any separate archaeological-find duty.

Under article 1324(3), failure to comply, appropriation despite knowing the owner, or concealment from the owner of the containing property forfeits the paragraph 1 rights to the State. That includes rights the finder may also have as owner of the containing property. The unverified effect of the proposed 2026 revisions and any special heritage rules prevents treating this older account as a complete current treasure regime.

A current finder reporting recipient, deadline and archaeological discovery procedure could not be confirmed. That uncertainty is not a conclusion that reporting is optional. Permission to enter or search, reporting a discovery and becoming its owner remain separate questions.

What to resolve before a search

Confirm the lawful land-use holder, any protected-area or tourism-zone designation, the applicable management and access conditions, and whether the proposed search or digging needs separate authorization. For a protected-area sacred forest or sacred site, the captured framework also requires prior community authorization for access. A land-access agreement alone does not resolve the other questions.

The general national detecting rule, current keeping and reporting rules, and complete detecting conditions for monuments, beaches, forests, parks and privately used land all remain unconfirmed. The sources provide specific background and restrictions, but not a complete current consolidation or all local rules.

This guide concerns Guinea-Bissau, including its mainland and islands where the cited instruments apply. It does not assume that Portuguese law or the law of Guinea applies. An older law available online, a legislative proposal or visitor access cannot by itself establish current permission to detect.
