How to Start a Mining Business: 8 Steps With Costs
To start a mining business: pick a deposit you can reach, secure the claim or licence, get permits and a mine ID, fund the build and sign a buyer. Sourced fees, timelines, costs and a monthly profit calculator below.

Key takeaways
- S&P Global’s database shows about 20 years from discovery to first production in Australia and almost 29 in the US (S&P Global, 2024); small pits on land you control can move faster.
- A new US federal lode claim costs US$49 location, US$25 processing and US$200 maintenance in year one, then US$200 a year (BLM California notice, 2026).
- US operators need a mine ID (MSHA Form 7000-51), a legal identity report (Form 2000-7) and a training plan before mining; BLM wants a financial guarantee for notice or plan work.
- Initial capital ranges from about US$36 million for a small Nevada heap-leach gold project to US$2,070 million for Copper World (company releases, 2026).
- The world average gold all-in sustaining cost was US$1,785 per ounce in the first quarter of 2026 (World Gold Council); test your plan well below the spot price.

To start a mining business you need five things in this order: a deposit you can legally reach, a claim or licence over it, the permits and safety registration to dig, money for equipment and working costs, and a buyer for what comes out. Starting a mine from scratch is slow. S&P Global’s database shows about 20 years on average from discovery to first production in Australia and almost 29 in the United States (S&P Global, June 2024). Small operators move faster by starting with sand, gravel, crushed stone or a small gold property, or by buying or leasing a mine that already has permits.
This guide is for licence and claim owners, consultants and investors who want to know how to start a mine or a mining company, what each step costs and how long it takes. It gives sourced fees and project examples, a table of start-up stages, a monthly profit calculator and a set of answers to the questions people search most. It covers metals and minerals only, and it is information, not legal or investment advice.
How to start a mining business in 8 steps
Every mine, from a gravel pit to a copper mine, passes through the same eight steps. Only the size, cost and time change.

Mining business ideas: which mine can a small company start
Most people who search for a mining business idea do not want a billion-dollar copper project. They want something one or two partners can finance. The US Geological Survey (USGS) shows where small and mid-size operators already work: in construction materials. In 2025 an estimated 1,400 companies ran 3,500 crushed stone quarries and 3,400 companies ran 6,500 construction sand and gravel pits, while gold came from more than 40 lode mines (hard-rock mines) plus placer operations (workings that recover gold from gravel and sand in streams or old river beds) (USGS, 2026; gold, USGS 2026).
Chart

Operating US sites in 2025 (USGS estimates)
| Business type | US sites in 2025 (USGS) | Companies | Output (million metric tons) | Average value (2025 estimate; per metric ton, gold per troy ounce) |
|---|---|---|---|---|

Read the table as a map of entry points. Aggregates earn little per tonne, so they only pay when the pit is close to the customer; the business is really a trucking and permitting business. Industrial sand sells at a higher price per tonne but has few sites, so a new entrant must win contracts with a small number of buyers. Gold sells for by far the highest price per unit of weight, and its output is the most concentrated, with a few large operations doing nearly all of it. A small gold mine can still work on a narrow, high-grade vein or a placer, but the margin depends on the price you receive and the grade you really mine, which is why the profit section below uses a calculator.
Other routes exist: gemstones and dimension stone, small base-metal or lithium projects sold to a larger company after drilling, or a service business that supplies drilling, assaying or surveys to mine owners. Whichever you choose, check three things before spending more: the deposit exists, you can get the rights to it, and someone will pay for the product at a price that covers your costs.
Step 1: Find and prove a deposit you can access
Begin with desk work, which costs little. Collect government geological maps, past drill logs, mineral occurrence databases and any assessment reports filed on nearby claims. Ask a qualified geologist to turn them into a plan: where to sample, which rock types and structures to test, and what grade and size would make the ground worth developing. Grade is the amount of metal in each tonne of rock, given for gold in grams per tonne (g/t). A mine needs enough tonnes at a grade above its cut-off grade, the lowest grade that still pays for mining and processing.
Chart
Years from discovery to first production
Gold and copper, world versus United States
The commodity changes the timeline. S&P Global found that gold mines are developed fastest, at 20.8 years on average from discovery to production worldwide, while copper takes 24.1 years; the US figures are 24.2 years for gold and 31.8 years for copper (S&P Global, 2024). These are averages across S&P’s mine database; the US figure also counts idle projects as starting by 2030. A small quarry or placer can open in far less time, but no source gives an average for them, so plan from your own permit calendar.
Satellite screening is one way to rank ground before you pay for field crews. Farmonaut turns a licence boundary (KML, KMZ or polygon) into a satellite mineral detection report in 5 to 20 business days, mapping alteration and other surface signs as exploration targets, ahead of any resource estimate. It is a first filter, not proof of ore, and drilling decides what is there. See the satellite-based mineral detection service and the Farmonaut guide to mineral prospectivity mapping for the method.
Use the same imagery to check what sits on top of the ore. Good rock can be unmineable when the surface is a town, a protected area or a water body, so look at land use before you stake or buy.
โถ When the gold is under a town: why strong ground can still be unmineable if land access is blocked. ยท 2:05
Step 2: Secure the land and mineral rights
You need two separate rights in most countries: the right to the minerals and the right to use the surface. In the United States, locatable minerals such as gold, silver and copper on federal land are held by staking a mining claim with the Bureau of Land Management (BLM). BLM California’s notice for the 2027 assessment year lists the first-year cost of a new claim located on or after 1 September 2026 as a US$49 location fee, a US$25 processing fee and a US$200 maintenance fee, and then US$200 per claim each year, due by 1 September. For a placer claim the maintenance fee is US$200 for each 20 acres or part of 20 acres (BLM California, 2026). Some states add their own recording and annual filing fees. The notice also describes a maintenance fee waiver certification for qualifying claimants, so check which one applies to you.
On private land, you deal with the owner: a purchase, a mining lease (a contract that lets you mine for a set period against payments) or an option (the right to buy or lease later, for a fee). Buy the mineral rights, not only the surface, and confirm with a title search that they have not been split off or leased to someone else.
Step 2 also covers people. Talk to neighbours, local councils and Indigenous or customary landholders early; Queensland, for example, requires applicants for a new mining lease to notify landholders and gives them the chance to object and seek compensation (Business Queensland).
Mining licence rules in the US, Canada, Australia and Ghana
The names differ, but the pattern is the same: a cheap right to explore first, then a more demanding right to mine. Always read the regulator’s current rules, because fees and eligibility change.
United States
Exploration on BLM land that disturbs 5 acres or less needs a notice filed 15 days before work starts. Anything bigger, or any bulk sample of 1,000 tons or more of presumed ore, needs a plan of operations approved by BLM before work begins (43 CFR 3809.21; 43 CFR 3809.11). A plan of operations is the document that describes where you will dig, how you will process, and how you will protect water and restore the land.
Canada
Canada’s provinces run their own systems. In Ontario you must register an account in the Mining Lands Administration System and hold a valid prospector’s licence before you can register a claim online (Ontario government). Other provinces have their own online staking tools and fee schedules.
Australia
States and territories grant rights. In Queensland, Business Queensland lists a prospecting permit, exploration permit or, for coal, a mineral development licence as the prerequisite authority for a mining lease, and says native title requirements must be addressed before an authority is granted (Business Queensland).
Ghana
Ghana’s Minerals Commission says a small-scale mining licence may be granted to Ghanaian citizens only, and that every mining lease granted by the Minister must be ratified by Parliament. A non-citizen can hold rights to industrial minerals such as clay, sand, granite or salt only with a proposed investment of at least US$10 million (Minerals Commission, overview of Act 703). Our own video below covers the three routes it found open to foreigners who want a small-scale licence in Africa.
For the legal meaning of a concession, see the Farmonaut explainer on what a mining concession is.
โถ Can foreigners get a small-scale mining licence in Africa? A short explainer on the three routes that are open. ยท 5:16
Step 3: Get permits, a bond and a mine ID
Permits cover what you do to the ground, air and water. On US federal land, BLM requires a financial guarantee (a bond or similar security that pays for reclamation if you walk away) before work under a notice or a plan of operations. Only casual use, meaning very light activity such as hand panning, needs none (43 CFR 3809.500). Larger projects go through an environmental review. S&P Global notes that the National Environmental Policy Act process producing an environmental impact statement is estimated by the government to take about four years, and that agencies often take years just to deem a plan of operations complete (S&P Global, 2024). State, county and water permits come on top.
Safety registration comes before the first shovel. In the US, the Mine Safety and Health Administration (MSHA) asks a new operator to contact the district office before any mining activity, complete Form 7000-51 to get a unique mine identification number, file Form 2000-7 to set out the legal identity of the operator, and build a training plan for miners (MSHA New Operator Toolkit). Other countries have their own mine inspectorates with similar registration steps.
Keep a permit calendar from day one. Write down each permit, the agency, the review time it publishes, and which later steps wait on it. Most delays come from a missing document or a late baseline study, not from the final decision.
How long does it take to open a mine?
The honest answer is: years, and it varies by country. Based on S&P Global’s database, the average time from discovery to first production is about 20 years in Australia, 27 in Canada, almost 29 in the United States and 34 in Zambia. S&P assumes in the US figure that projects not yet in production start by 2030, so it is a planning guide, not a promise for any one project.
Chart
Average years from discovery to first production
By country, S&P Global mine database
The figures are long because they start at discovery, which may be decades before anyone applies for a permit. Your clock starts when you hold the rights. From that point, drilling, studies, permits and building take several years even for a small project, and permitting alone can take years in jurisdictions with a full environmental review. A quarry on private land with local permits is the fastest route; an underground gold or copper mine on federal land is the slowest.
How much does it cost to start a mining business?
Cost depends on the size of the project more than on the commodity. The table below gives sourced anchors for each stage. Where no public average exists, it says what drives the price so you can ask for quotes.
| Stage | What you pay for | Sourced anchor |
|---|---|---|
| Claims or licence | Filing, location and annual fees | New US federal lode claim, first year: US$49 location, US$25 processing, US$200 maintenance (BLM California notice, 2026) |
| Exploration | Mapping, sampling, geophysics, drilling, assays | Drilling cost varies with depth, rock and country; get contractor quotes |
| Studies | Preliminary economic assessment, then pre-feasibility and feasibility studies | Priced by the consultant; scope grows with project size |
| Permits and bond | Baseline studies, applications, reclamation guarantee | Bond amount is the agency’s estimate of reclamation cost for each plan (43 CFR 3809.552) |
| Build | Pit or portals, plant, power, water, roads, camp | Borealis Sandman gold project, Nevada: about US$36 million initial capital for a heap-leach mine of about 38,000 oz a year (preliminary study, February 2026) |
| Large build | Mine and 60,000 tons per day concentrator | Hudbay Copper World, Arizona: US$2,070 million initial growth capital in 2026 dollars over 36 months (feasibility study, October 2026) |
A preliminary economic assessment (PEA) is an early study that tests whether a project could pay; the Sandman figures come from one, at a US$2,600 per ounce gold price and with life-of-mine capital of about US$57 million including sustaining and working capital (Borealis Mining, Sandman project page). A PEA is not a decision-grade study. Capital cost can change a lot before construction. Hudbay says its Copper World capital rose from the 2023 study, in part from about US$200 million of scope changes (Hudbay, October 2026).
How is it paid for? Large projects mix sources. Copper World’s plan uses a US$600 million joint-venture equity investment from Mitsubishi, a US$230 million deposit from Wheaton Precious Metals under an existing metals stream (a deal where a buyer pays up front for a share of future metal), and about US$650 million of project-level debt, with the rest from the owners (same Hudbay release). A small startup usually relies on its own savings, partners, equipment leases and a smaller stream or royalty, and lenders want a feasibility study and permits before they commit. For the royalty route see the Farmonaut guide to mine development companies, types and costs.
Mining business profit per month: how to work it out
No honest average exists for a small mine’s monthly profit, because grade, recovery, price and cost per tonne differ so much. The calculation itself is simple: sales minus mining, processing and overhead cost, minus royalty. Use the calculator below with your own numbers.
Chart
Average gold price, US$ per troy ounce
2021 to 2025 (2025 is a USGS estimate)
Two public numbers help you set the cost side. The World Gold Council reports that the global average all-in sustaining cost (AISC) for gold producers was US$1,785 per ounce in the first quarter of 2026, up 16% on the year, with an average margin of US$3,076 per ounce (World Gold Council, 2026). AISC adds sustaining capital, general costs and some closure cost to the direct operating cost of each ounce. It describes large producers, so a small mine with less scale will usually run at a higher cost per ounce. The spot gold price was US$4,127.40 per troy ounce on 5 November 2026 (Kitco). Gold prices move daily, so use the day’s price when you run the numbers.
Margins swing with the price. The USGS lists the average gold price at US$1,801 per troy ounce in 2021 and an estimated US$3,300 in 2025 (USGS, 2026). A mine with fixed costs of a few hundred thousand dollars a month can be strongly profitable at one price and lose money at another, so test your plan at a price well below today’s. The Farmonaut explainer Is mining a good business? Margins and AISC by metal compares margins across metals.
Calculator
What could a small gold mine earn per month?
Enter your own tonnes, grade, recovery, price and costs.
- Gold sold per month (oz): 205.0
- Sales after royalty (US$): $795,248
- Break-even grade (g/t): 1.04
- Months to repay start-up capital: 10.7
Example values only, not a benchmark or a forecast. Gold price is an input: example, use today’s price (US$ per troy ounce). Royalty is taken on sales; costs are per tonne mined and processed plus fixed monthly overhead. Sourced context: World Gold Council AISC US$1,785 per ounce for large producers (Q1 2026).
Step 4: Plan safety, water and community from day one
Design the health, safety and environment plan before you design the pit. It should cover a risk assessment for each task, emergency response and rescue, incident reporting, dust control, water management, handling of waste rock and tailings (the fine waste left after processing), and how you will talk to neighbours. In the US the MSHA training plan and mine ID are legal requirements, not extras. Insurers, lenders and permitting agencies all ask to see this plan.
Community agreements matter as much as technical design. Hire locally where you can, publish a contact for complaints, and share monitoring results. Projects that skip this step often face objections at the permit stage, which adds the delay and legal cost you are trying to avoid.
โถ The 7 environmental impacts of mining, explained in clay with satellite maps. ยท 2:31
Step 5: Choose the mining method and the plant
The shape and depth of the ore decide the method. Open-pit mining suits ore near the surface across a wide area. Underground mining suits deep or narrow veins, with higher up-front cost for shafts or declines (sloping tunnels) and ventilation. Placer mining recovers gold or gemstones from sand and gravel. Quarries and sand and gravel pits are open-pit operations that excavate rock or loose material for construction.
Then size the plant: crushing, grinding, separation or leaching, power supply, water supply, tailings storage, access roads and a camp or housing. Start with the smallest plant that proves the economics and leave room to expand. Test the ore at a laboratory first: ore that is hard to process (a refractory ore) can change the recovery, and so the whole financial model. For help with the contractors and engineers who design and build, see the guide to mine development companies.
Step 6: Build the company and the team
Set up a legal company for the mine. Separating the mine from other assets protects you, and regulators and banks expect it. In the US, the MSHA legal identity report records who the operator is, so it must match the company that holds the permits. Open a bank account, take out insurance, and keep records for royalties, tax and the bond.
A small mine needs a core team: a mine manager, a geologist, a surveyor, a processing or plant lead, a safety officer and an environmental lead. Hire contractors for drilling, blasting and haulage while volumes are small. Take advice from a mining lawyer on title and a tax adviser on royalties and depreciation, because both change after production starts. If you plan to raise money on a stock exchange, follow its technical reporting rules, which set who is allowed to sign off resource and reserve figures.
Step 7: Line up buyers before you dig
A mine without a buyer is a pile of rock. Gold dorรฉ (the rough bars poured at the mine) and concentrate go to refiners or traders under a sales agreement. Base-metal concentrate goes to smelters under a contract that sets the payable percentage and treatment charges. Aggregates, sand and stone sell to local contractors and are priced delivered, so check haulage distance first. Talk to the buyer before you build; they will tell you the specification, such as grain size for sand or minimum grade for concentrate, and that affects plant design.
An offtake agreement can also help with finance, because lenders value contracted sales. Do not sign away too much: if you sell at a fixed price and the market rises, you lose the upside. Keep volumes, delivery points and price formulas clear in writing.
Step 8: Plan closure and rehabilitation
Closure starts at design. Restore each area as it finishes, keep topsoil and store it for reuse, and plan the final shape of pits, dumps and water. On US federal land, BLM sets the financial guarantee at the estimated cost of reclamation as if BLM hired a third party to do the work (43 CFR 3809.552), so budget for that amount if you stop. A mine that has a closure plan, monitoring data and a clean record is easier to finance, to permit and to sell.
Some sites later become farmland, forest, solar or wind sites or light industry. Agree with the landowner and the community what the final use should be, then design toward it.
First 12 months: a startup timeline
This is a planning sequence, not a forecast. Months overlap, and permit time depends on your country and the size of the operation.
| Period | What you do | What must be finished before the next period |
|---|---|---|
| Months 1-2 | Choose commodity, desk study, satellite screening, check land use and ownership | A short list of sites with a clear owner |
| Months 2-4 | Stake or acquire the claim, licence or option; talk to the landowner and neighbours | Rights registered in your company’s name |
| Months 3-8 | Sampling, mapping and, if justified, a first drill programme; metallurgical test | Assays, a grade and tonnage estimate by a qualified person |
| Months 4-10 | Environmental baseline, plan of operations or equivalent, bond quote, MSHA or inspectorate registration | Complete applications filed; review clock running |
| Months 6-12 | Preliminary economic assessment, funding talks, buyer talks | A model that still pays at a lower metal price |
| After permits | Detailed design, equipment order, hiring, construction, start-up | Permits, bond, mine ID, training plan, buyer contract |
Buy, lease or option an existing mine instead
If you want to own a mine without waiting for a discovery to mature, look at ground that has already done some of the work. You can buy a closed or small operating mine, lease it with a production payment, or take an option while you test it. The seller may hold permits, a plant and records, and your risk shifts from finding ore to checking what is there and what it will cost to restart.
Before you pay, check title, outstanding fees, environmental liabilities and the status of the bond; read the old drill logs and have a geologist sample the ground. The Farmonaut guide on how to sell a mine covers valuation, buyers and deal types, which helps a buyer see what a seller will be asked for.
Frequently asked questions
How do I start a mining company with no experience?
Start by hiring the experience: a geologist to rate the ground, a mining lawyer for title and permits, and a mine manager or consultant for the plan. Form the company, secure rights to one small property, and finish a preliminary economic assessment before you raise money or order equipment.
How much money do I need to start a mine?
It ranges from a few thousand dollars for claim fees and sampling to tens of millions for a small heap-leach gold mine and billions for a large copper mine. A 2026 preliminary study for a Nevada gold project put initial capital at about US$36 million, and Hudbay’s Copper World feasibility study uses US$2,070 million. A small quarry costs less, but no public average exists, so ask equipment dealers and contractors for quotes.
How long does it take to start a mining business?
S&P Global’s 2024 data shows about 20 years from discovery to first production in Australia and almost 29 in the US. A small operation on land you already control can move in a few years, with permits as the main wait.
Is mining a good business?
It can be, but the profit depends on price, grade and cost. The World Gold Council reported an average gold margin of US$3,076 per ounce in the first quarter of 2026, but the first quarter of 2026 was the 28th consecutive year-on-year rise in the average AISC, and small mines usually face higher unit costs. See our guide on margins and AISC by metal.
What is the cheapest mining business to start?
Usually a sand, gravel or stone pit on land you own or lease, since the product needs little processing. It still needs local permits, MSHA registration in the US and a buyer nearby. USGS data shows thousands of such small sites already operate in the US.
Do I need a licence to start a mine?
Yes. You need the right to the minerals, the right to use the land, and permits for the work. In the US that usually means a claim or lease, BLM approval on federal land, state permits and an MSHA mine ID. Other countries use exploration and mining licences issued by a state or national regulator.
How do I find a mine to buy or a deposit to stake?
Search government claim and licence maps to see which ground is open, review geological surveys and old drill reports, and check land use. Satellite imagery can rank open ground by alteration and structure before you visit. Confirm everything on the ground and in the registry.
Can a foreigner start a mining business abroad?
Often yes, with limits. Ghana reserves small-scale licences for citizens, for example, but allows non-citizens to hold other rights through registered companies, and to hold industrial mineral rights with a US$10 million minimum investment (Minerals Commission). Check the law of the country and consider a local partner.
What does MSHA require for a new mine?
MSHA asks a new US operator to contact its district office, request a mine ID with Form 7000-51, file the legal identity report on Form 2000-7 and develop a training plan before work starts.
How is a mining business financed?
Early work is funded with equity and partners. Later stages add debt, a royalty or stream, or a joint venture; Copper World’s plan mixes all of these. Lenders ask for a feasibility study, permits, a bond and sales contracts first.
What can satellite data do for a new mining company?
It helps screen large areas before field work, flagging alteration and structures as exploration targets, and it shows land use and access. It does not prove ore or replace drilling. To discuss your site, send a request through the mining quote form or contact the team.
This page is for information only. It is not investment, legal or tax advice. Claim fees, permit rules and eligibility change; confirm them with the regulator and a qualified lawyer. Prospect only with the landowner’s and the regulator’s permission, follow safety rules, and never use mercury.
