Mining
Evergreen Surety places reclamation bonds, permit bonds, and construction performance and payment bonds for hard rock operators, coal companies, uranium producers, lithium developers, and aggregate producers across the United States. We are an independent surety bond agency specializing in federal and state mining financial assurance – with direct access to the carriers that underwrite these risks.
Mining bond programs are not a side practice here. If you need a bond and you operate in the mining sector, talk to a surety advisor today.
Reclamation bonds are long-term, noncancellable obligations. Most surety carriers won’t write them. Most agencies don’t have the carrier access to place them. When your bond requirement involves a 20-year commitment on federal land, a mine closure plan covering thousands of acres, or a state permitting process with its own methodology and forms, you need an agency that has built relationships specifically for that risk.
We’ve placed bonds for hard rock operators, coal companies, uranium producers, lithium developers, and aggregate producers across the Rocky Mountain West and nationally. We know the difference between how Colorado DRMS calculates bond amounts and how Nevada Division of Minerals does it. We’ve structured self-bonding transitions and know what each agency requires for substitution approval. Simply put, we obtain the results that our clients deserve.
We work with mining operators across every commodity and project stage
Our mining clients range from exploration-stage companies securing their first permit bond to producing mines managing multi-million dollar reclamation programs. We place bonds for hard rock operators, coal companies, uranium producers, lithium and critical minerals developers, potash and solution mining operations, molybdenum producers, aggregate and sand and gravel producers, and phosphate mining operations.
The bond types and obligees differ by commodity, by jurisdiction, and by project stage. An exploration-stage gold project in Nevada has different requirements than a producing copper mine in Arizona or a coal operator in Wyoming. We know the differences and we work with clients at every stage of the project lifecycle.
Get your federal reclamation bonds placed correctly
Federal reclamation bonds for hardrock mining run through the Bureau of Land Management and the U.S. Forest Service. Coal reclamation runs through OSMRE under SMCRA. The regulatory frameworks are different, the bond forms are different, and the approval processes are different. We can’t help with the permitting, but we can make obtaining the bond easy in comparison.
We work directly with federal agencies and understand what each requires. If a carrier declines which many, we have multiple access points to the carriers that specialize in these risks. We don’t send operators back to a letter of credit when surety bonds are an available option.
BLM and Forest Service hardrock reclamation bonds
Hardrock mining on federal land managed by the BLM or U.S. Forest Service requires reclamation bonds as a condition of the operator’s plan of operations. These bonds guarantee that the operator will restore disturbed land to an approved post-mining condition. Bond amounts are set by the agency based on estimated reclamation costs and can be substantial for large surface disturbance areas.
For operations on Forest Service land specifically, the bonding requirements and approval process run through the Forest Service’s own program and may involve both federal and state agency coordination. We’ve placed bonds for operators working under both regulatory frameworks and know the nuances of each.
OSMRE and SMCRA coal reclamation bonds
Coal mining reclamation is governed federally by the Surface Mining Control and Reclamation Act (SMCRA), with oversight from the Office of Surface Mining Reclamation and Enforcement (OSMRE). In states with approved primacy programs, including Wyoming, West Virginia, and Kentucky, the state agency administers the program under OSMRE oversight.
SMCRA reclamation bonds must be sufficient to cover the full estimated cost of reclamation if the state had to complete the work itself. That standard drives bond amounts and shapes what carriers will and won’t write. We place coal reclamation bonds and work with operators to understand their obligations before they engage the regulatory agency.
EPA environmental financial assurance bonds
The EPA and state environmental agencies may require financial assurance bonds for hazardous material compliance, including acid mine drainage remediation and tailings pond closure. These bonds are often separate from and in addition to the primary reclamation bond, and the obligee and bond form requirements differ from those of BLM or OSMRE.
Tailings storage facility bonds can be among the largest bond requirements a mining operator faces, particularly for operations with significant historical tailings footprints. We place these bonds and help operators understand the full scope of their environmental financial assurance obligations across all applicable agencies.
Meet your state bonding requirements without the guesswork
Each state mining agency has its own bond calculation methodology, its own forms, and its own approval timeline. What Colorado DRMS requires looks different from what the Nevada Division of Minerals requires, and both are different from the Arizona State Mine Inspector’s process. An operator who understands the methodology before walking into a permitting conversation is in a fundamentally better position than one who finds out at the end.
We work directly with Colorado DRMS, the Nevada Division of Minerals, the Arizona State Mine Inspector, Wyoming DEQ, the New Mexico Mining and Minerals Division, the Montana DEQ Hard Rock Mining Bureau, and the Idaho Department of Lands. We know each agency’s requirements, and we help clients prepare before the conversation with the obligee starts.
How bond amounts are calculated - and why it matters before you engage
Some state agencies use acreage-based formulas. Others rely on independent cost estimates prepared by qualified engineers. A few use a combination of both. The methodology drives the number, and the number drives both the bond premium and the limit of the financial assurance you’re carrying on your books.
Mining permit bonds and mineral lease bonds
State mining permit bonds are required to obtain or maintain an active mining permit. Mineral lease bonds are required for operations on federal or state-administered mineral leases. BLM operator bonds cover surface-disturbing activities on BLM-managed land separate from the reclamation bond. State severance tax bonds guarantee payment of mineral severance taxes in states that require them.
These bonds are often more straightforward to place than long-term reclamation bonds, but they still require an agency that understands the obligee and the regulatory context. We place the full range of regulatory and permit bonds across all major mining states.
Water rights and water use bonds
Mining operations often involve significant water use, and some states require financial assurance bonds for mining water appropriations as a condition of water rights permits. Requirements vary by state and by the nature of the water use. We place water rights bonds in states where mining operations require them as part of their permitting obligations.
Transitioning off self-bonding? We've done this before
Self-bonding, where an operator guarantees its own reclamation obligations based on financial strength rather than posting a third-party bond, has been an accepted form of financial assurance in some states for decades. That’s changing. States are tightening self-bonding eligibility standards, and operators who previously qualified are now being required to post surety.
The transition isn’t simple. Each agency has its own substitution approval process, its own documentation requirements, and its own timeline for accepting the new bond and releasing the self-bond. Some require concurrent coverage during the transition period. Some have specific bond form requirements for substitution bonds that differ from new permit bonds.
We’ve structured these transitions and know what each agency needs to approve the substitution without disrupting operations. If your company is facing a self-bonding transition,contact us before you engage the agency. Getting the sequencing and documentation right from the start matters.
Performance and payment bonds for mine construction
Mining construction projects, including new mine builds, expansions, processing facility upgrades, tailings storage facility construction, require the same performance and payment bonds as any major construction project. The principal needs to guarantee contractor performance and protect subcontractors and suppliers in the event of a default.
We place performance and payment bonds for mine construction across all commodity sectors and project types. We also place supply contract bonds that guarantee delivery on mineral supply agreements, decommissioning bonds for funded closure plan obligations, and underground storage tank bonds for fuel storage on mine sites.
We place bonds for the emerging critical minerals sector too
The domestic lithium and rare earth element sectors are growing fast, driven by battery demand, electric vehicle supply chains, and federal critical minerals policy. Bond requirements for these projects are significant as they involve the same BLM, state agency, and environmental financial assurance obligations as any other hardrock mining operation. The surety content and agency expertise available to operators in these sectors is nearly nonexistent right now.
We’re positioned to serve lithium and critical minerals operators now, not after the market matures. If you’re developing a lithium or rare earth project and need to understand your bonding obligations, we’re one of the few agencies that can have that conversation with any depth.
Lithium mining surety bonds
Lithium operations, whether brine extraction in Nevada or Arkansas, or hard rock lithium mining in other states,will carry federal and state reclamation bond requirements similar to other hardrock mining operations. BLM and state agency oversight applies depending on land status. Bond amounts are driven by the same cost estimation methodologies used for other minerals.
The lithium sector is moving quickly and regulatory requirements are still developing in some jurisdictions. An agency that tracks the regulatory landscape closely, and one that has carrier access for hardrock reclamation bonds, is the right agency for a lithium developer to be working with.
Rare earth element financial assurance
Rare earth element mining carries federal bonding requirements under BLM and Forest Service oversight for operations on federal land. Projects like MP Materials’ Mountain Pass facility in California operate under federal bonding obligations that require carrier access and regulatory familiarity that most surety agencies don’t have.
The REE sector is early-stage in the United States but growing with strong federal policy support. Bond requirements will grow with the sector. We’re ahead of that curve.
Don't let a letter of credit be your default answer
Long-term reclamation obligations have historically pushed mining operators toward cash deposits and letters of credit for financial assurance, not because these products are the better option, but because surety wasn’t available or the right agency wasn’t there to place it.
Noncancellable reclamation bonds are genuinely harder to place than most bond types. Surety carriers are reluctant to underwrite perpetual arrangements, and availability is limited. That’s the honest reality. But limited doesn’t mean impossible, and it doesn’t mean the only alternative is tying up cash or drawing on your banking capacity with a letter of credit.
We have multiple carrier access points specifically for energy and reclamation risks. We know which carriers have appetites for long-term mining reclamation bonds and which ones don’t. When the first carrier says no, we keep going. That persistence is a core part of how Evergreen operates and how we’ve built our reputation in this space.
Where a bond alone won’t satisfy the obligee, a surety-backed letter of credit may be the right solution. The principal gets the on-demand payment language the obligee requires, without restricting cash or reducing banking capacity. We place these instruments as well.
Why mining operators work with Evergreen Surety
We do surety only. No insurance products competing for attention, no account managers handling mining bonds as an afterthought alongside commercial lines renewals. The people you’re working with have spent their careers on this specific problem.
We have carrier relationships built for complex energy and reclamation risks, including the noncancellable long-term bonds that most agencies can’t place. We’re appointed with 15 different carriers, which means when one says no we have real alternatives, not just the same carrier through a different door.
We work alongside your CPAs, bankers, and attorneys. Mining operators deal with complex regulatory, legal, and financial structures. When a bond placement requires coordination with your legal counsel on bond form language, or with your lender on how a reclamation bond interacts with your credit facility, we do that as a matter of course.
Let's talk about your bond program
Whether you’re securing your first mining permit bond, managing a multi-million dollar reclamation program, transitioning off self-bonding, or developing a lithium or critical minerals project with bonding requirements you’re still working through, please give us a call.
