Mine Feasibility Study in South Carolina
Longmire & Co. writes mine feasibility studies for operators, developers, and investors working on industrial minerals, kaolin, vermiculite projects in South Carolina. Our job is to tell you, clearly and honestly, whether the project in front of you actually makes sense to build — before you spend the kind of money on it that's hard to get back.
The South Carolina setting
Piedmont and Coastal Plain industrial mineral and clay districts. The question for a feasibility study isn't whether mineralization exists — it's whether the deposit, the access, and the processing path together support a project that can actually be built and financed.
The state's Mining Act bond formulas and county-level interaction typically drive site selection. A useful report works through each of those pieces in order: how confident we are in the resource, how it would be mined, what we expect to recover, what it will cost to build, what it will cost to run, and what the project is worth at the end if commodity prices and costs come in around where they sit today.
Permitting and approvals in South Carolina
State permitting in South Carolina runs through SCDES Mining Section, with federal agencies involved when federal land, water, or listed species come into the picture. For a feasibility study, the important part isn't the list of permits — it's a realistic schedule: which permit has to come first, how long similar projects have taken, and what kind of bond or financial assurance the project will need to post.
The state's Mining Act bond formulas and county-level interaction typically drive site selection. The report addresses each of these directly — including a reasonable timeline, a working estimate of the bonding requirement, and a clear look at what a permitting delay would do to the project's return.
Built for lenders and investors
If the report is going to a lender or equity partner, it has to do more than show a positive NPV. It has to show the work — where the resource estimate comes from, how we picked the price deck, how the capital and operating costs are built up, and where the project is most sensitive. That's how we write our South Carolina reports.
In the first conversation, we'll be straightforward about whether the project calls for a scoping-level study, a pre-feasibility study (PFS), or a full bankable feasibility study (BFS) — because the cost and timeline for each is meaningfully different, and you shouldn't be paying for more report than the situation calls for.
Frequently asked
What level of feasibility study do I need for a South Carolina mining project?
It depends on who the report is for. A scoping study is enough for an internal decision on whether to keep spending on exploration. A pre-feasibility study (PFS) is the right step when you're showing the project to potential financial partners but aren't yet ready for a final investment decision. A bankable feasibility study (BFS) is what a lender or equity partner will expect before committing capital. We'll help you figure out which one your project actually needs.
How do you handle permitting timing in the financial model?
Honestly, and out in the open. We build a real schedule for the SCDES Mining Section process — plus any federal coordination — and then show what a six, twelve, or twenty-four month delay would do to the project's NPV and IRR. That way the timing risk is visible to everyone reading the report.
What commodities and operations do you cover in South Carolina?
We cover industrial minerals, kaolin, vermiculite projects in South Carolina — from new development to expansion of an existing operation to in-situ recovery where it applies. The basic structure of the report is the same; the commodity and process details get adapted to the specific project.
Is your report suitable for project finance use?
Yes. The report is built for lender and equity IC use, with independent resource treatment, an explicit price deck, capital and operating costs documented at the line-item level, sensitivities run at the points that matter most, and a clear-eyed look at the risks the report can't eliminate.
