Guyana licenses gold ground in acres, charges rent per acre per year, and splits its permits by scale. Most of the country is rainforest sitting on deeply weathered Guiana Shield rock, which changes what a satellite can and cannot tell you. This article explains the permit ladder, the actual rates, the geology and the data that GGMC now gives away.

Audience Permit holders, explorers, investors
Anyone starting gold exploration in Guyana meets two facts almost immediately. The first is that the permit system is simple compared with many countries, with four rungs from a small-scale claim to a large-scale mining licence. The second is that the ground is hard: thick forest, deep tropical weathering and a river network that doubles as the road system. Satellites help with some of that and are blind to the rest, so it pays to know which is which before you plan a season.
Gold exploration in Guyana is also unusually dependent on a few public documents, and this article quotes them directly. The sections below follow the order in which a project usually unfolds: geology first, then who can hold which permit, then the rental and royalty numbers, then the data and imagery you can use before sending anyone to the interior.

“Mining accounted for 63% of Guyana’s mapped deforestation in 2020, about 6,452 hectares.”
Dense canopy blocks optical sensors from seeing rock. At the same time, every pit, dredge scar and mining road leaves a bright, mappable disturbance. A satellite is poor at reading gold geology through jungle and very good at telling you who has already been digging.
Gold exploration in Guyana starts with the Guiana Shield greenstone belts
Northern Guyana lies on the Guiana Shield, a basement block of more than 900,000 km² along the northern edge of the Amazonian Craton. A 2018 study of the 9 Mile deposit by Bassoo and Murphy in the Brazilian Journal of Geology describes the shield’s greenstone belts as intruded by granitoids and hosting many orogenic gold deposits, which the authors link to the Trans-Amazonian orogeny. In Guyana the belt of interest is the Barama-Mazaruni greenstone belt.
The same paper describes the working conditions plainly. Intense tropical weathering turns the upper part of the bedrock into saprolite, and the terrain is remote, so fresh rock exposures are scarce. Exploration itself often provides the fresh samples that make geological study possible. That sentence describes a lot of what follows in this article.
Shear zones and veins: the 9 Mile example for gold exploration in Guyana
The 9 Mile deposit sits in the Makapa-Kuribrong Shear Zone, a northwest-trending structure about 600 km long that crosses the shield. Gold occurs in quartz veins along a northeast-trending thrust contact between meta-rhyolite and granodiorite and in veins along a younger, steeply dipping east-west shear zone. The deposit produced about 82,000 ounces of gold from quartz veins between 1987 and 2000, which makes it a modest historical producer but a good teaching example: structure controls everything, and structure is what remote sensing can sometimes pick up.
Where the digging actually happens
Guyana’s forest-monitoring report gives a useful picture of where gold mining in Guyana takes place. It says mining is concentrated in the centre of the country, that most of the activity is inside the State Forest Area, and that change over the years since 1990 clusters around existing road infrastructure and navigable rivers. The same report notes that the area mined in 2020 sat well below the 2012 level, when the gold price was the highest since 1980, and that after 2012 the price fell to around US$1,200 an ounce, which together with limited access gradually reduced the area mined.
For anyone doing gold exploration in Guyana, that pattern is the context for every decision. Ground near rivers and roads has been worked hardest, so the opportunity for a new permit holder is more often in the gaps and extensions, along structures that older operations did not follow, than on virgin ground beside an active pit. Reading those gaps requires knowing where the pits are, and that is exactly what recent satellite scenes record.
Oko West: a different style in the same belt
Company material for the Oko West project, in the Cuyuni-Mazaruni area about 95 km from Georgetown, describes a contact between the Barama-Mazaruni greenstone belt on the west and the Oko pluton on the east. Mineralisation is orogenic, in volcaniclastic, siliciclastic and carbonaceous sedimentary rocks forming a tabular body that dips gently east, with silica, carbonate and sericite alteration and sulphide-bearing quartz veins. The company, rather than an independent body, is the source of these descriptions, and reserve numbers quoted on its page are undated, so treat the project as an example of style rather than a resource statement.
| Item | What the sources say | Why it matters for exploration |
|---|---|---|
| Host belt | Barama-Mazaruni greenstone belt, intruded by granitoids | Gold follows contacts and shears between greenstone and intrusions |
| Weathering | Upper bedrock converted to saprolite | Soil and saprolite geochemistry beat rock sampling; outcrop is rare |
| Main structure | Makapa-Kuribrong Shear Zone, about 600 km | Traces of this structure are the first screening target |
| Access | Remote interior, rivers and mining roads | Planning a season depends on logistics as much as geology |
| Forest | About 18 million of 21.1 million hectares | Optical reflectance of rock is usually blocked by canopy |

Who can hold what for gold exploration in Guyana: the GGMC and the Mining Act
The Guyana Geology and Mines Commission (GGMC) administers mineral rights under the Mining Act 1989 (Cap. 65:01). The GGMC fiscal-regime note, dated July 2025, lays out the ladder. A small-scale operator takes a prospecting permit (small scale) and then a claim licence for a parcel typically 800 by 1,500 feet. The medium scale uses a Prospecting Permit (Medium Scale) and then a Mining Permit (Medium Scale), for 150 to 1,200 acres. Large-scale operators use a Prospecting Licence covering 500 to 12,800 acres and then a Mining Licence.
The GGMC’s FAQ adds the rules that matter to foreign readers. Medium-scale permits are open to Guyanese citizens and to institutions whose beneficial owners are all Guyanese, under section 57(2) of the Mining Act. A medium-scale prospecting permit runs for 12 months and renews in 12-month periods. A mining permit, which requires a valid prospecting permit, runs for five years and renews for up to five years at a time or the life of the deposit, whichever is shorter.
| Scale | Exploration title | Production title | Size | Who can hold |
|---|---|---|---|---|
| Small | Prospecting permit (small scale) | Claim licence (land claim 1,500 by 800 ft; river claim one mile of a navigable river) | One claim | Not stated on the GGMC page |
| Medium | Prospecting Permit (PPMS) | Mining Permit (MP) | 150 to 1,200 acres | Guyanese citizens and all-Guyanese institutions |
| Large | Prospecting Licence | Mining Licence | 500 to 12,800 acres | Not stated on the GGMC page |
How a medium-scale prospecting permit is processed
GGMC describes the process as five stages. You submit Form 5A with a map and a cartographic description of the area, a deposit, the application fee, proof of address and, for companies, registration documents. GGMC checks whether the area is available. If it is, the stock sheet is updated and a notice of intention to grant is published in the Official Gazette. If nobody objects, you pay the difference in rental and the permit is issued. If the area is not available you are told and can reclaim the deposit, though application fees are not refunded.
Checking the ground
GGMC says land availability is checked on the stock map at the Land Management Section at its headquarters or at any mining station, and that maps of mineral property status can be bought there. Its site also links to an ArcGIS Mineral Tenure map. For transactions, GGMC runs eServices, where the property and claim rentals section covers single claims, claims by range, prospecting licences, mining permits and medium-scale prospecting permits. Our broader guide to mining cadastre portals by country compares Guyana’s approach with other jurisdictions.
A tenure map is only as current as its last update. Confirm a neighbour’s position with GGMC’s Land Management Section and, where you can, with a GPS in the field, before you assume a boundary on a screen is correct.
What gold exploration in Guyana costs per acre
The GGMC fiscal note gives the main rates. A small-scale prospecting permit carries a nominal fee of about US$7.50 a year (GYD 1,500), and a claim licence has a flat annual rental of around US$10. Medium-scale titles are charged per acre: the prospecting permit rental starts at US$0.25 per acre in year one and rises by US$0.10 each year, so US$0.35 in year two and US$0.45 in year three. Converting to a medium-scale mining permit costs US$1.00 per acre a year. For large-scale work, the Prospecting Licence costs US$0.50 per acre in year one, US$0.60 in year two and US$1.00 in year three, with a performance bond of 10% of the planned annual exploration budget and an application fee of about US$100. A large-scale Mining Licence then pays US$5.00 per acre a year.
The GGMC’s own claims page lists different small-scale figures (GYD 1,000 a year for a land claim and GYD 2,000 for a river claim), and the FAQ gives a US$0.13 per acre deposit for medium-scale prospecting permits. Older gazetted orders give other amounts again. Rates are set in regulations that change, so use the schedule published by GGMC on the day you apply.
Guyana prospecting rental and bond calculator
Assumptions: medium scale rental is US$0.25 per acre in year 1 plus US$0.10 per acre for each later year (GGMC FAQ and fiscal note), valid for 150 to 1,200 acres and Guyanese applicants only. Large scale rental is US$0.50, US$0.60 and US$1.00 per acre in years 1 to 3 (fiscal note), valid for 500 to 12,800 acres, with an application fee of about US$100 and a bond of 10% of the planned annual exploration budget; the calculator caps large-scale at three years because later rates are not confirmed here. Excludes application fees for medium scale, environmental bonds on mining, royalties and costs of fieldwork. Confirm with GGMC.
Two worked examples show how the calculator behaves. A 1,200-acre medium-scale prospecting permit held for three years pays 1,200 times (0.25 + 0.35 + 0.45), or US$1,260 in rent. If a screen shows that 40% of the block is flooded savanna, ground already claimed or forest on barren granite, and you keep 720 acres, rent falls to US$756, a saving of US$504. A 5,000-acre large-scale prospecting licence over three years pays 5,000 times (0.50 + 0.60 + 1.00), or US$10,500, plus a US$100 application fee and a bond equal to 10% of the planned annual budget, so US$40,000 against a US$400,000 programme. Keeping 3,000 acres brings rent down to US$6,300.
Those numbers are not large against the cost of a programme. What they do show is that rent scales cleanly with acreage, while the real cost of gold exploration in Guyana scales with logistics and the bond. A block trimmed to the structures that matter is cheaper at every line.
At the defaults a 1,000-acre medium-scale permit costs US$1,050 in rent over three years. That is a small line next to getting people and supplies into the interior. The more useful question for screening is which parts of a 1,000-acre block deserve the field logistics at all.
Royalty and tax after gold exploration in Guyana succeeds
The same GGMC fiscal note covers what happens after a discovery, which matters to anyone modelling gold mining in Guyana. Since all subsoil minerals are vested in the State, production is subject to royalty. For gold, the standard royalty is 5% of production value at every scale, although large-scale agreements now commonly apply an elevated 8% when gold exceeds US$1,000 an ounce. Small and medium producers pay a 2% withholding tax on gross gold and diamond sales as a final income tax. Large companies pay corporate tax, with a statutory 40% for commercial companies, but recent large-scale gold agreements fix the rate between 27% and 30%. Gold royalties are collected through the Guyana Gold Board.
What satellites can see through the forest in gold exploration in Guyana
Guyana’s own forest monitoring system gives the best local evidence of what satellites do well. The Guyana Forestry Commission’s 2020 monitoring report puts the national land area at 21.1 million hectares and the forest at about 18 million. It estimates 10,232 hectares of deforestation in 2020, with mining the main driver at 6,452 hectares, fire at 2,933 hectares and forestry at around 195 hectares. From 2017 the monitoring has used Sentinel-2 imagery at 10 m pixels as its primary dataset, with Landsat as a supplement, and for 2020 it acquired 400 tiles between August and December, including 201 cloudless Sentinel composites.
For gold exploration in Guyana the lesson is two-sided. Mining disturbance, pits, tailings, dredge scars and roads, is easy to see and to map from space. Cloud is the opposite lesson: it took hundreds of tiles to assemble cloudless coverage for one national assessment, which tells you how hard it is to get a clean optical scene over a single block.
Radar, optical and the cloud problem
Two kinds of sensor do most of the work in the tropics. Synthetic aperture radar sees through cloud and gives a clean surface-roughness and structure signal, which suits a forested country where optical scenes are often unusable. Optical imagery gives the spectral information that radar cannot, but only where cloud and canopy allow. A practical screen for gold exploration in Guyana combines both, uses the dry-season scenes where they exist, and is honest about the share of the block it could not read.
That honesty is worth asking any supplier for. A report that colours an entire forested polygon with confident anomalies is describing leaves. A report that marks canopy-covered ground as unreadable and concentrates its ranking on structure, clearings and drainage is describing the block.
What to expect from a screen of a Guyanese block
- ✔ Existing disturbance. A first screen for gold exploration in Guyana usually starts here. Pits, dredge scars, tailings and tracks, dated by scene, tell you where others have found gold and who may already be on the ground you hope to hold.
- ✔ Structure and drainage. Radar and elevation data show lineaments and drainage offsets through canopy better than optical data do, which is how a shear like the Makapa-Kuribrong is traced.
- ⚠ Rock mineralogy under canopy. Optical alteration indices need bare ground. Under continuous forest they mostly measure leaves.
- ⚠ Saprolite. The weathering profile described by Bassoo and Murphy means that clay and iron signals from the surface can be products of weathering rather than hydrothermal alteration.
- 📊 Open ground. Mining clearings, savanna patches and river banks are where optical alteration mapping can work, and they are also where the gold has been found so far.
Mining is the largest mapped driver of forest loss in Guyana’s own monitoring. Screening a block from orbit before cutting a trail narrows where any disturbance is needed. Environmental authorisation is a separate step that the EPA enforces under the Environmental Protection Act 1996.
Free data for gold exploration in Guyana: the GGMC airborne survey and tenure maps
The best new dataset for gold exploration in Guyana is the GGMC’s 2025 airborne survey, part of Phase II of the Mineral Mapping Study of Guyana’s mineral resources. The survey page lists a magnetic and radiometric survey over 12,264 km², with traverse lines 400 m apart, tie lines 2,400 m apart and 37,266 line-kilometres flown. Residual magnetic intensity and reduced-to-pole magnetic maps, ternary radiometric maps, shapefiles, GeoTIFFs and KMZ files are available through a request form that emails a one-time download link. The page also directs other data requests to a Mineral Mapping Information Request form.
For gold exploration in Guyana, magnetics are what make shear zones and greenstone-granitoid contacts visible under forest and saprolite. A satellite screen that is laid over those grids is far stronger than either alone.

A sensible sequence for gold exploration in Guyana
- Pick the scale. Gold exploration in Guyana is organised around it. Decide whether you are a small-scale claim holder, a medium-scale Guyanese permit holder or a large-scale applicant, since each has different area limits and rules.
- Download the airborne data for the block and mark shears and contacts, the cheapest evidence available for gold exploration in Guyana.
- Screen the polygon from space for disturbance, structure, drainage and open ground.
- Check tenure on the ArcGIS map and at GGMC’s Land Management Section.
- File for the ranked ground and budget the rental, deposit and bonds.
- Sample the saprolite along lines across the interpreted structures.
Step 3 is where we work. Our satellite-based mineral detection takes a polygon (KML, KMZ or coordinates) and the target mineral, analyses multispectral and hyperspectral data, and returns prospectivity heatmaps, high-potential zones with estimated location and depth ranges, geological interpretation and georeferenced GIS files, within 5 to 20 business days. The Premium+ report adds TargetMax drilling intelligence and 3D subsurface models. We have covered 100,000+ hectares for 20+ mineral types in 25+ countries, and early-stage screening can cut early-exploration cost by up to 80 to 85% and timelines from months to days. For Guyana we are straightforward about the limits above: forest and weathering mean results are strongest on open ground and structure, and weakest on continuously canopied rock.

Frequently asked questions
Who regulates gold exploration in Guyana?
Gold exploration in Guyana is regulated by the Guyana Geology and Mines Commission (GGMC), under the Mining Act 1989. Environmental authorisation is handled by the Environmental Protection Agency under the Environmental Protection Act 1996.
What are the permit sizes in Guyana?
Small-scale claims are typically 1,500 by 800 feet, with river claims covering one mile of a navigable river. Medium-scale permits cover 150 to 1,200 acres, and large-scale prospecting and mining licences cover 500 to 12,800 acres.
Can a foreign company get a medium-scale permit?
GGMC’s FAQ says medium-scale permits are for Guyanese citizens and institutions whose beneficial owners are all Guyanese, under section 57(2) of the Mining Act. Foreign companies generally need the large-scale route. Ask GGMC and take legal advice.
How much does a prospecting permit cost per acre?
A medium-scale prospecting permit costs US$0.25 per acre in the first year and US$0.10 more each year. A large-scale prospecting licence costs US$0.50, US$0.60 and US$1.00 per acre in years one to three. Confirm the current schedule with GGMC.
Where is most gold mining in Guyana concentrated?
The Guyana Forestry Commission’s 2020 report says mining activity is consolidated in the centre of the country, mostly within the State Forest Area, with change clustered around roads and navigable rivers. Its mining extent in 2020 was below the 2012 level.
What does gold prospecting in Guyana involve on the small scale?
GGMC describes a small-scale prospecting permit as a general permit to search for minerals within a mining district, at a nominal annual fee of about US$7.50, followed by a claim licence for a parcel of around 800 by 1,500 feet at roughly US$10 a year. Figures on GGMC’s own claims page differ, so check the current schedule.
What is the royalty on gold in Guyana?
The standard gold royalty is 5% of production value for all scales, with large-scale agreements often using 8% when gold is above US$1,000 per ounce, according to the GGMC fiscal note. Small and medium producers also pay a 2% withholding tax on sales.
Can satellites find gold through the Guyanese rainforest?
For gold exploration in Guyana, not through continuous canopy with optical sensors. Radar and elevation data can show structure, and imagery shows existing mining disturbance and open ground very well. Airborne magnetics and soil sampling remain the main tools for locating gold under forest.
Is there free geophysical data for Guyana?
Yes. GGMC’s 2025 airborne survey page offers magnetic, radiometric and related files, including shapefiles, GeoTIFFs and KMZ, through a request form that sends a one-time download link.
Reviewed October 2026 against the GGMC fiscal-regime note (July 2025), GGMC Common Queries and claims pages, GGMC’s airborne survey page, the Guyana MRVS 2020 report, the Bassoo and Murphy paper on the 9 Mile deposit and company information for Oko West.
