What does a GroundControl analysis examine?

GroundControl examines every claim in a portfolio against all recorded mining claim polygons in the area and against excluded-lands polygons (patented, fee, state, withdrawn). It identifies seniority conflicts, discovery monument placement issues, body overlaps, and acreage reductions. Each finding names the specific senior claim serial number so counsel can investigate.

What is mining claim seniority?

Mining claim seniority is determined by location date. Earlier-dated claims have senior rights. Where claim boundaries overlap, the senior claim generally controls the disputed ground. GroundControl identifies every senior-junior overlap in a portfolio and calculates the acreage impact.

GroundControl — Mining Claim Seniority, Overlap & Validity Analysis

GroundControl is a geometric and temporal analysis tool that examines an entire mining claim portfolio against every recorded claim polygon and excluded-lands boundary in the area. It identifies seniority conflicts, invalid discovery monument placement, body overlaps, and acreage reductions — then names the specific senior claims causing each conflict so counsel can investigate. No one else has this capability.

What GroundControl Examines

Every claim in the subject portfolio is analyzed against two layers:

All recorded mining claim polygons in the area — identifying where subject claims overlap earlier-dated (senior) claims. Each overlap is measured by acreage and the specific senior claim serial number is identified.
Excluded-lands polygons — patented land, fee land, state land, withdrawn land, and other areas closed to mineral entry. Any subject claim body or discovery monument falling within excluded lands is flagged.

The analysis is temporal — it uses location dates to determine seniority. Earlier-dated claims are senior. Where boundaries overlap, the senior claim controls the disputed ground.

Outcome Classifications

Classification

Valid

Claim is intact. No carving by seniors or excluded-lands polygons. No DM conflict.

Classification

Reduced

Claim is partially affected by exclusions, senior overlaps, or both. Acreage loss is calculated.

Classification

Fully Overstaked

Claim body is 100% overlapped by earlier-dated claims. No remaining acreage.

Classification

Invalid Claim

Discovery monument falls within a senior claim boundary or excluded-lands polygon.

What the Report Delivers

Executive summary — overall portfolio health: percentage valid, reduced, overstaked, and invalid. Total acreage accounting from original to remaining.
Claim-by-claim findings — every affected claim listed with its specific geometric observation, the senior claim serial numbers involved, and original/excluded/senior-reduced/remaining acreage.
Discovery monument analysis — flags any DM coordinates falling within a senior claim boundary or excluded-lands polygon. DM placement issues are the most critical finding because they can affect the validity of the entire claim.
Acreage accounting — original acreage versus remaining acreage after excluded-lands carve-outs and senior overlaps. Reported at the claim level and rolled up to the portfolio level.
Senior claim identification — every senior claim causing a conflict is identified by serial number, so counsel can investigate ownership, current status, and chain of title.
Publication-ready maps — ArcGIS Pro layouts showing subject claims, senior overlaps, excluded-lands polygons, DM locations, and conflict zones.
Excel workbook — full claim inventory with outcome classifications, acreage fields, and conflict details on sortable tabs.

What GroundControl is Not

GroundControl describes geometric and temporal facts from BLM administrative records. It is not a legal opinion, title examination, boundary survey, or chain-of-title analysis. Mining claim validity rules vary by state and by interaction with federal withdrawals, state selections, and other overlapping dispositions. The legal effect of any geometric finding is a question for counsel.

The findings are built for attorney review. Counsel determines whether a particular DM conflict, body overlap, or excluded-lands carve-out renders a claim invalid, reduced, or defensible.

Who Needs GroundControl

Mining companies that have staked a claim block and need to verify what they actually hold before committing development capital.
Mineral title attorneys preparing opinions of title or supporting acquisition closings who need a verified geometric baseline for every claim in the portfolio.
Acquirers and investors evaluating a claim portfolio as part of a transaction who need to know how much of the stated acreage actually survives seniority and exclusion analysis.
Land departments managing large portfolios who need to identify and triage conflicts across hundreds or thousands of claims.
Exploration teams planning drill programs who need to confirm their target sections are on valid, uncontested ground before permitting.

How It Fits the ClaimWatch Workflow

GroundControl is typically the last step in the ClaimWatch product lifecycle:

Regional Prospecting identifies the play and ranks candidate parcels.
Area Check verifies the specific area — claims, land status, and ownership.
Claim Staking stakes the ground with automated packages.
GroundControl examines the staked block and confirms what you actually control.
