Reduce overlap

All enabled layers at normal contrast.

Turn inspection on, then tap the map to list overlapping boundaries and nearby markers. Only loaded, enabled layers are included.

Mineral evidence & location

Green point
Official mineral occurrence; no mapped park overlap. Other permissions remain unchecked.
Red point
Official occurrence inside a mapped protected park; fossicking prohibited there.
Amber point
Recorded location uncertainty reaches a protected park; check the exact boundary.
Broad circle
Approximate report/locality guide, not a deposit or access boundary. Amber means its guide area overlaps protected park land; red means the guide centre is inside a park. Dashed circles are community reports.
White-centred point / wide dashed ring
Mount Gravatt starting point / selected straight-line search radius. The radius is not driving distance.
Orange outline
Selected record’s location uncertainty or approximate guide circle; not a permission boundary.

Land designations & restrictions

Blue solid outline / forward hatching
Official fossicking area. A licence, current conditions and exclusions apply.
Purple dashed outline / backward hatching
Designated fossicking land. Mining interests may coexist; check exclusions and area conditions.
Teal dotted outline / horizontal hatching
General permission area (GPA). General permission is subject to the landholder’s conditions; camping permission is separate.
Red dotted outline / crosshatching
Explicit no-go section within an official fossicking layer. Fossicking is not permitted in that section.
Red solid outline / vertical hatching
National or conservation park. Fossicking prohibited. Other protected-land categories are not comprehensively mapped.

Camping-prohibited sections retain their designation colour; read the popup warning. Overlap never overrides a restriction. Counts in the sidebar include restricted subsections.

Geology overlays

Tan
Mapped units described as igneous rocks.
Mauve
Mapped units described as phyllite, schist, gneiss or quartzite.
Sage
Other mapped units. Colours simplify source descriptions; open the polygon for the actual unit.
Lilac dashed outline
Inferred silica-host analogy: Chillingham Volcanics. It does not predict a pocket or establish access.

Geology, park screening and mineral records use the 29 October 2026 snapshot. Official fossicking boundaries are checked live; see their sidebar for the last successful check or fallback date.

What this map can tell you

This is a research map, not a prediction of undiscovered deposits or permission to collect.

What the dates mean

“GSQ date current” and “GSQ date recorded” are database fields, not dates of verified recent discoveries. The downloaded data does not provide a last field confirmation date. Community page review dates are research dates, not dates someone confirmed minerals on the ground. The data snapshot was downloaded on 29 October 2026.

Satellite / aerial imagery

Switch Map view to Satellite / aerial to use Esri World Imagery. The imagery date panel queries Esri metadata at the map centre for the current scale. Capture dates and coverage vary by place and zoom; a release date is not a capture date. Where the metadata query supplies no capture date, the panel says so. Imagery is not live, and may not show recent earthworks, floods, vegetation changes or access conditions.

Official foundation

2,144 MINOCC records were downloaded in full using pagination for the rectangle 151–154° E, 26–29° S. Points were returned in EPSG:4326. Search includes all recorded commodity codes, not just the main commodity.

Each point is spatially joined to GSQ Detailed Surface Geology (layer 15). The downloaded geometry was generalised by 0.00015°; the display overlay is rounded to 4 decimals. At contacts and within a record’s positional error, check the original map. Mapped surface rock is not necessarily the mineralised host, especially under alluvium.

Community evidence

Reports are manually curated public discussions. A single post is one lead, not independent confirmation. Town-centre coordinates and broad guide circles are explicitly approximate; they are not find locations. Garden, road-fill and beach material can have a transported origin. No geological claim is inferred merely from a nearby post.

Inferred silica host areas

The optional inference layer highlights mapped units whose name contains Chillingham Volcanics. The Back Creek amethyst/quartz and Thunderbird Park thunderegg records intersect this named volcanic unit. This is a host-rock analogy only: facies, cavities, alteration and preservation vary within a unit. Highlighted polygons do not predict a pocket. Access remains unchecked.

No artificial probability

Entries are labelled “official record”, “reported locality” or “community lead”. Results sort by distance. Record counts may include multiple historical records for the same workings; they are not a count of distinct deposits. There is no percentage chance of finding a pocket: geological maps cannot resolve cavities at that scale. Absence in MINOCC does not demonstrate absence of a mineral; accessory minerals and small finds may be unrecorded.

Fluorite / sapphire / spinel

No fluorite is encoded in this regional MINOCC extract. A local fluorite pocket has not been verified. A searchable journal reference for Mount Ngun-Ngun is a literature lead only; its mineralogy has not been verified here and the national park prohibits collecting. Sapphire and spinel have sparse regional records, some beyond a practical two-hour drive.

Reading overlapping layers

Open Legend & map controls for symbol meanings, a layer-focus selector and a hatching/outline choice. Fossicking areas use forward diagonal hatching; designated land uses the opposite diagonal; GPAs use horizontal lines; protected parks use vertical lines; no-go sections use a denser crosshatch. Transparent backgrounds let overlapping hatch directions remain visible. White contrast edging separates the outlines from the basemap. Mineral points remain above boundary polygons. Layer focus fades other layers without changing data or permissions; no-go sections remain prominent. Overlap inspection lists loaded, enabled boundaries at the tapped point, plus nearby mineral markers within 12 screen pixels and approximate report circles. It is a visual inspection tool, not a legal boundary or access determination.

Official fossicking boundaries

Three independent overlays show Fossicking areas (blue), Designated fossicking land (purple dashed) and General permission areas (teal dotted). These are the official Queensland Mining Administrative Areas layers 11, 15 and 20. The map first loads a complete statewide boundary snapshot retrieved on 29 October 2026, then checks the official service for current records. The sidebar reports the last successful check; if the service is unavailable the saved snapshot remains visible. These dates describe retrieval, not a guarantee of field access.

Layer categories come from the official source, not the locality name: for example a place named “State Forest Fossicking Area” can be classified as a GPA. Source comments and links are included in boundary popups. No-go sections are marked red and labelled as prohibited; camping-prohibited sections retain their designation and carry a separate warning. Boundaries can contain exclusions and do not override current area conditions, mining interests or closures. A mineral occurrence or a no-park-overlap result is not permission to fossick. The statewide boundary overlays are independent of the mineral list, radius and mineral exports.

Protected park overlap screening

Each recorded coordinate was checked against the official Queensland “Protected areas and forests of Queensland” layer 10, downloaded on 29 October 2026. All national park types and conservation parks in the dataset are included. A point inside a mapped park is labelled “Fossicking prohibited”. A point outside whose recorded GSQ location-accuracy circle intersects a park is labelled “Possible park overlap”. Broad community guide circles are assessed as areas, not precise find points: an overlap does not mean the whole guide circle is prohibited.

The checks use original, unsimplified polygon coordinates and account for polygon holes. Short boundary distances use a local tangent approximation in metres, so circle-edge results are screening only. The boundary source warns that it must not be used as a definitive absolute reserve boundary location. No-overlap is not a determination of legal access. Cadastre, council reserves, wildlife reserves outside this layer, mining tenure, native title, forestry permissions and other restrictions have not been comprehensively checked.

Official protected-area boundary source and accuracy warning

Access is a separate decision

Other land-access and current mining-tenure intersections have not been performed. Queensland requires a fossicking licence. Landholder and mining permissions may also apply. Fossicking is prohibited in national parks; state forests require an applicable general permission area. Do not enter old workings. Check current rules and boundaries before a trip.
