Selling a Mining business

Mining deals usually come down to what’s true on the ground. Buyers pressure-test reserve life and the mine plan, cost per ton, permit exposure, closure exposure, and whether the fleet and crew will keep tonnes moving after the handover.

Reserve Life

What buyers determine

Buyers are checking that the reserve story matches what the scale tickets and plant feeds have actually shown. They price the uncertainty around confidence categories, grade swings, dilution, and whether you have a track record of honest reconciliation.

How to prepare

  • Package your latest reserve/resource statement (or internal tonnage/grade method) and label confidence levels
  • Show model-to-mine-to-plant reconciliation over multiple quarters (tonnes, grade, recovery/yield)
  • Call out problem zones (water, clay, variable benches) and the operating plan for each
  • Start with a reserve-life summary. Share detailed models and pit maps after qualification
Great answer
At the current shipped run-rate of about 62k tons per month, we have 9.2 years of permitted reserve life. Over the last 8 quarters, planned vs. mined tonnes have been within 4–6%, and the main grade/yield variability sits in two benches on the north wall, which we schedule in dry months with adjusted blasting and plant settings. The data room has the reserve summary, assumptions, and reconciliation plots. Detailed pit maps come after a qualified site visit.
Good answer
We’re comfortable we have multiple years left at today’s pace, and we can walk you through where we’ve mined and what’s next. We have reserve estimates and planning notes, but the reconciliation package is still being pulled together.
Red flag
We’ve got plenty of rock. We don’t track reserve life closely. We just open new areas when we need to.
How Rejigg helps:Rejigg lets you share reserve summaries first and gate detailed models and maps until a buyer is vetted and under NDA.
What’s the current life-of-mine plan and strip ratio, and when was the plan last updated?
Deal-critical
Mine Plan

What buyers determine

Buyers want to know the plan works in a real pit with real roads, weather, and equipment limits. They also look for signs you understand the next pushback, development work, and capex, rather than leaving it for the next owner.

How to prepare

  • Provide the latest mine plan with strip ratio, benches, haul profiles, and equipment match
  • Show plan vs. actual for strip, tonnes, and haul, plus the operational reasons
  • List critical constraints (crusher, pumps, power, haul roads) and what you’re doing about them
  • Document the capex and development needed to reach the next mining area
Great answer
The LOM plan was updated last quarter. It assumes a 0.85:1 strip ratio for the next 24 months, rising to about 1.15:1 as we deepen the south pushback. Over the last 12 months, actual strip averaged 0.88:1, with wet-season road softening as the main driver, and we corrected that with a reroute and base rebuild. The plan includes phase-by-phase haul distances, the equipment set, and the development and capex needed to open the next area.
Good answer
We have a plan and can explain the next phases, but we still need a clean plan-versus-actual package. Strip ratio and haul distances are understood by the team, but the documentation isn’t presentation-ready.
Red flag
We don’t really run off a mine plan. We mine what’s easiest and keep production up. Strip ratio moves around.
How Rejigg helps:Rejigg’s data room keeps the mine plan and plan-vs-actual support together so diligence doesn’t turn into weeks of email threads.
What permit conditions could shut down a pit, and do they transfer with ownership changes or require re-review?
Deal-critical
Permits

What buyers determine

Buyers are looking for stop-work risk, renewal and transfer timing, and day-to-day compliance with dust, blasting, water, traffic, and setbacks. They also read inspection patterns and complaints as a signal of regulator posture and community tolerance.

How to prepare

  • Create a permit register with renewal dates and change-of-control/transfer steps
  • Summarize operating constraints: blasting windows, dust/noise limits, discharge limits, traffic, and setbacks
  • Compile inspection and enforcement history with close-out proof and dates
  • Document community and landholder commitments that affect operations
Great answer
We keep a permit register with renewal dates and the change-of-control steps. The main gating item is the water discharge permit, which requires agency notice and updated financial assurance paperwork. In the last 24 months, we’ve had two routine inspections with minor findings, both closed within 30 days, and we track dust, noise, and blasting compliance weekly. We also maintain a written complaint process with a log and documented resolutions.
Good answer
Permits are in good standing, and we haven’t had major issues. We still need to pull renewal dates, transfer requirements, and inspection close-outs into one consolidated package.
Red flag
Permits are fine. If something comes up, we’ll handle it then.
How Rejigg helps:Rejigg lets you share a tight permit register and close-out evidence while gating sensitive expansion details until the buyer is fully qualified.
What’s your current reclamation plan and its cost, and how does your bond work if costs change?
Deal-critical
Closure & Bonds

What buyers determine

Buyers are underwriting the real closure check and the capital tied up in bonding. They want to see whether liabilities are shrinking through progressive reclamation or growing through new disturbance, and whether bond replacement will be straightforward after a change of control.

How to prepare

  • Share the closure plan, current bond instruments, and the bond calculation and adjustment rules
  • Show progressive reclamation with photos, dates, quantities, and regulator sign-offs when available
  • Get early estimates for long-lead liabilities like water treatment, tailings, and dewatering impacts
  • Clarify liability ownership and transfer mechanics, including any legacy disturbance
Great answer
Our current bond is $4.6M via surety. It’s recalculated annually based on disturbed acres and unit reclamation costs, and we can share the worksheet and the increase triggers. We’ve reclaimed 18 acres over the last three seasons, with photo logs and regulator correspondence. The closure cost estimate was updated last year and covers dewatering and post-closure water monitoring, with a stated contingency range.
Good answer
We have a closure plan and bond in place, and we’ve done some progressive reclamation. The closure estimate is due for an update, and our supporting evidence needs to be organized more cleanly.
Red flag
Closure is far off, and the bond is just a cost of doing business. It shouldn’t matter in a sale.
How Rejigg helps:Rejigg helps you organize bond documents, closure plans, and reclamation proof so buyers can diligence liabilities without stalling the deal.
What are your costs for getting a ton on the ground and shipping it, and how do you handle price jumps in diesel, explosives, or tires?
Deal-critical
Unit Costs

What buyers determine

Buyers want real mine-site unit economics by the drivers that swing margins, like diesel, powder, power, wear parts, and labor. They also look for indexation and single-source supply exposure, since parts lead times and vendor terms can decide whether you keep shipping.

How to prepare

  • Break cost per ton into drill/blast, load/haul, crush/screen, maintenance, fuel, tires/GET, labor
  • Separate contractor vs. owner-performed work and document pass-through and index clauses
  • Provide key supply agreements and lead times for liners, motors, pumps, and tires
  • Build a diesel/powder/power sensitivity view and the operational levers you can pull
Great answer
Over the last 12 months, all-in site cost averaged $8.72 per ton shipped. The biggest buckets are load/haul at $2.40, crush/screen at $1.95, and fuel at $1.30. Diesel is indexed on freight and part of our hauling, but explosives are not, so we manage that risk through powder factor, timing, and blast design discipline. We can share vendor terms, recent tire and liner pricing, and the changes we’ve used to hold costs steady.
Good answer
We know our approximate cost per ton and the main drivers, and we can explain what moves with diesel and parts. The bucket-level detail and contract indexation are not fully cleaned up yet.
Red flag
Mining costs move around. We don’t track cost per ton very precisely.
How Rejigg helps:Rejigg helps you present a clean cost-per-ton breakdown with the contracts and maintenance records that back it up.
What key assets could halt production if they fail, and what rebuilds should we plan for in the next 6–12 months?
Deal-critical
Fleet & Plant

What buyers determine

Buyers are estimating near-term capex and the odds of a production-stopping outage. They care less about age and more about rebuild cadence, downtime causes, spares, and whether you can actually get parts in time.

How to prepare

  • Build an equipment schedule with hours, rebuild history, and next major spend per asset
  • Summarize downtime drivers for fixed plant, and mobile availability/utilization if you track it
  • Document maintenance backlog and deferrals with a 12-month catch-up plan
  • List critical spares and long-lead components with on-hand inventory and supplier lead times
Great answer
The two single-point-of-failure items are the primary crusher motor and the wash plant feed pump. We keep critical spares on site and have confirmed lead times with suppliers. On mobile, the 988 loader is at 18,400 hours, had major components done at 16,900, and the next planned spend is a transmission in Q4 at about $220k. We track unplanned downtime by cause, and the last 12 months have improved after we adjusted liner change intervals and added vibration monitoring.
Good answer
We know what can stop production, and we can provide maintenance records. We still need a clear 6–12-month view of backlog, downtime causes, and rebuild timing.
Red flag
The fleet is in good shape for its age. If something breaks, we fix it.
How Rejigg helps:Rejigg keeps fleet lists, rebuild records, and downtime logs organized and permissioned so buyers can underwrite capex risk quickly.
Have there been any serious incidents or citations in recent years, and what were their root causes?
Important
Safety Culture

What buyers determine

Buyers treat safety as a predictor of uptime and leadership discipline. They look for consistent reporting, real corrective actions, and fewer repeat issues, since serious incidents can trigger stoppages, insurance spikes, contractor problems, and regulator scrutiny.

How to prepare

  • Compile incidents and near-misses with corrective actions and close-out proof
  • Summarize MSHA/OSHA citations with root-cause themes and repeat-item controls
  • Document contractor controls: inductions, permits to work, LOTO, traffic plans during shutdowns
  • Show routines: pre-shifts, training cadence, competency sign-offs, and audit results
Great answer
Over the last 36 months, we’ve had zero fatalities and one lost-time incident. Here’s the investigation summary, the changes we made, and the follow-up audits that verified the fix. Our top recurring risks are traffic management, LOTO during maintenance, and blasting exclusion, and we can show training completion and supervisor field audits for each. Our citation file includes root causes and close-outs, and we track repeat items specifically.
Good answer
We have a solid record and take safety seriously. We still need to consolidate incidents, citations, and close-out evidence into one diligence-ready package.
Red flag
We don’t have safety problems. Mining is dangerous, and paperwork isn’t our focus.
How Rejigg helps:Rejigg lets you share incidents, citations, and corrective-action proof in one controlled place so buyers don’t fill gaps with assumptions.
Do you own or lease the land, and what royalties apply, how are they calculated, and are there any minimums?
Important
Land & Royalties

What buyers determine

Buyers are confirming the right to mine. That includes title, boundaries, easements, surface access, and whether any informal access deals will survive closing. They also model royalty and lease terms straight into unit costs, renewal risk, and potential disputes.

How to prepare

  • Provide maps for owned vs. leased tracts, easements, haul-road ROW (Right of Way), and operating boundaries
  • Summarize royalty and lease terms: rate, escalators, minimums, audit rights, renewals, termination triggers
  • Convert informal access arrangements into written, assignable agreements when possible
  • Flag expansion areas that require new access or renegotiation
Great answer
We mine across three owned parcels and two leased tracts. Here are the boundaries, easements, and haul road ROW documents. The royalty is $0.42 per ton with a CPI escalator and no minimum, and the lease has two five-year renewal options with assignment permitted on sale. We also had one informal access arrangement, and we converted it into a written, transferable easement to remove closing risk.
Good answer
We can explain what’s owned vs. leased and the basic royalty rate. We still need to assemble the full document chain and clean up a couple of older access arrangements.
Red flag
We’ve always used that road, and it hasn’t been an issue. Royalties are whatever the landowner wants, and it’s not formal.
How Rejigg helps:Rejigg helps you share tract maps and lease and royalty documents with qualified buyers without broadly exposing your land position.
Who approves the blasting plan and who do the team members actually look to as the mine manager?
Important
Owner Dependence

What buyers determine

Buyers want to know whether the operation runs on repeatable systems or one person’s memory. They look for coverage on blast design, ground control, plant settings, permit routines, and customer specs, because key-person gaps often lead to holdbacks and longer transitions.

How to prepare

  • Assign each critical decision to a named owner plus a trained backup
  • Document real routines: pit walkdowns, pre-shifts, downtime calls, parts ordering, contractor oversight
  • Build retention plans for key supervisors and trades, and pressure-test who might leave
  • Write a 30/60/90-day transition plan, plus longer technical support if needed
Great answer
Blast design is signed off by our contracted blasting engineer, and day-to-day patterns and tie-ins are run by the mine superintendent, with a trained backup on the alternate roster. The owner has led regulator communication, and we documented the permit routines and introduced our compliance lead to inspectors over the last two quarters. We can share the org chart, SOPs, and a 90-day transition plan that includes retention commitments for key roles.
Good answer
The team is strong, and the site runs if the owner is gone for a week. We still have gaps in documented routines and formal backup coverage for a few critical roles.
Red flag
I’m the only one who really knows the pit and the regulators. The buyer can figure it out after closing.
How Rejigg helps:Rejigg helps you document key roles, backups, and transition commitments so buyers can underwrite continuity with less discounting.

Customers & Pricing

What buyers determine

Buyers are testing demand stability, customer concentration, and how pricing actually gets set in your local market. For many quarries, trucking radius, permitted competition, and spec performance drive stickiness, so buyers look for evidence those advantages hold up.

How to prepare

  • Break out tons and revenue by product, top customers, and end-market
  • Document pricing method by customer type and any volume commitments or take-or-pay terms
  • Show QC process, plus history of spec misses and corrective actions
  • Summarize seasonality and project concentration with a simple monthly volume view
Great answer
Our top five customers represent 57% of tons, mostly ready-mix and asphalt plants within a 35-mile radius. Switching is uncommon because we’re the closest permitted quarry that consistently hits their gradation spec. Pricing is mixed: two anchor accounts reset annually, public-works volume is bid-driven, and smaller loads are spot. We can show realized price by product by month. We had one fines issue last year, corrected it with wash plant adjustments, and documented the QC checks.
Good answer
We know our major customers and the basic pricing approach. We haven’t packaged realized price and volume by product and customer, along with QC proof, into a buyer-ready summary.
Red flag
Customers come and go. Pricing is whatever the market will pay.
How Rejigg helps:Rejigg lets you share customer and pricing summaries under NDA without leaking customer-specific pricing into a small local market.

Straight from buyer evaluations

“Most of their revenue comes from replacement parts and service work, not selling new equipment. Customers keep coming back year after year because the parts wear out and need replacing. That steady income is exactly what made me confident in this business.”
Repeat RevenueBuyer impressed by repeat revenue at a crushing equipment company
“They source everything domestically, so when supply chains got messy during the pandemic, their customers never missed a beat. That reliability is why people stay loyal, and it's not something you can build overnight.”
Reliable Supply ChainBuyer seeing how domestic sourcing kept customers happy
“The engineering team can solve problems that bigger companies won't even look at. They custom-build machines for specific jobs, and that know-how is what keeps customers calling them first.”
Technical ExpertiseBuyer impressed by technical skills at a niche equipment manufacturer
“Infrastructure spending is strong right now, and this company has a five-year warranty that's twice what anyone else offers. Customers remember that, and they come back when it's time to reorder parts.”
Growing DemandBuyer seeing the benefit of strong warranties and infrastructure demand
“The quarry feeds the trucks, the trucks serve the contractors, and the yard handles walk-in sales. Each part of the business supports the others. It's a smart setup that you don't see very often.”
Connected OperationsBuyer impressed by how different parts of the operation work together

How buyers value this type of business

Where you land in that range depends on how much of your revenue comes from repeat parts and service work versus one-time equipment sales, and whether the business keeps running when you take a week off.

3x–8x
annual profit
Depending on team, recurring revenue, and how much runs without you

What drives a premium

  • Customers who keep coming back for parts
    When a big chunk of your revenue comes from replacement parts and service work, buyers see income they can count on year after year.
  • Reliable sourcing that keeps customers happy
    Getting your materials from domestic suppliers means shorter wait times and fewer headaches, which is a real selling point.
  • Permits and reserves in good standing
    Active mining permits and proven reserves show a buyer there's plenty of work ahead without having to start from scratch.
  • A wide range of customers
    Selling to lots of different contractors and operators in different areas means the business doesn't depend on any single customer.
