Colorado Mining Properties Excel Database
Budget: $2 – $8 USD
Here’s the game plan:
• Target: Silver, copper, gold, and rare earth element deposits, past-producing silver mines, or silver-rich polymetallic projects (Ag-Cu-Au) in Colorado. Areas like Silver Cliff (Custer County), La Plata (Durango area), or even smaller claim sets in Park County are all on the radar.
• Where to look:
• BLM active claim database and Colorado DRMS for historical mines/production records.
• Prospectors/claim owners who might be looking to option or sell.
• Listings like Juniorminers.com or local mining clubs (Custer, San Juan, etc.).
• What we need:
• Any data on grades (silver oz/t or g/t), past production numbers, or assays.
• Accessibility (roads, infrastructure).
• Claim status (patented/unpatented, active vs. open ground).
Can you start pulling together leads — especially in Colorado — that fit this profile? Let’s focus on things with at least some existing data (old reports, assays, production history), so it looks credible when we present it.
Where to Get the Information
Can assign the third party to mine data from these key sources:
Government & Public Databases
• BLM LR2000 / MLRS (Mining Claim Database) → shows active mining claims, owners, commodities.
• Colorado DRMS (Division of Reclamation, Mining & Safety) → historic mine production, reports, maps.
• USGS MRDS (Mineral Resources Data System) → searchable by county/commodity, includes silver/copper/gold occurrences.
Industry & Listings
• Juniorminers.com → active claims for sale with descriptions and assays.
• Minelistings.com / Land Matters → property listings, often with maps & contacts.
• Company websites & press releases → e.g. Metallic Minerals (La Plata), Viscount (Silver Cliff).
Local / Community
• County courthouses & assessor databases → land/claim ownership records.
• Mining clubs & societies (Colorado Mining Association, Denver Mineral Show contacts).
• Local prospectors / brokers → often advertise on forums or Facebook groups.
How to Compile It
• Start broad: Pull every silver/copper/silver-rich gold claim in Colorado from BLM + USGS + DRMS.
• Filter down: Keep only those with some supporting data (historic production, assays, past drilling).
• Add contact details: Where available (claim owner, broker, company IR contact).
• Check credibility: Look for supporting documentation (old reports, drill results, geologic maps).
⸻
4. Workflow:
1. Data Gathering – scrape/download from BLM, DRMS, MRDS, juniors’ sites.
2. Data Entry – populate spreadsheet columns (one project per row).
3. Verification – spot check claims: does silver actually show up in assays, or is it just speculative?
4. Prioritization – rank projects:
• Tier 1 = past producers with assays and access (ready to present to Viscount).
• Tier 2 = known deposits, early data but promising.
• Tier 3 = speculative/low-data (keep on file).
5. Export – deliver as an Excel/CSV file with hyperlinks to sources.
Sample Path to Pulling Contact Info for These Mines
Find current ownership / contact info for Kate & Passiflora mines:
1. Pull the latest public disclosure from Viscount Mining:
• Their website, press releases, NI 43-101 resource estimate reports. Look for sections about ownership, claim maps.
2. Check with Custer County Recorder/Assessor:
• Search for the names “Kate”, “Passiflora”, “Herman Passiflora” mines or lode claims. See who is listed as claimant or deed owner for those parcels.
3. Search BLM claim records (if they are unpatented or federal):
• Using latitude/longitude from MRDS. BLM claim locator tools may show active claim owner.
4. Contact DRMS in Colorado:
• Ask if they have files for Kate or Passiflora showing current status, custody, or last filed operator.
5. Use mining registries like MRDS, The Diggings, WesternMiningHistory to gather historic owner names, then try to trace whether those names are still active (or have leases/options been transferred).
6. Once you have names (company or person), lookup contact information:
• Business registries (Colorado Secretary of State) for companies.
• Assessor’s office or county clerk for individual names.
• Local mining lawyer or broker listings.
How to Get the Missing Info (Title / Contact)
Here’s how to close the gaps and get owner, parcel, and contact info:
1. County Recorder / Assessor / Clerk, Custer County, CO
• Search the property / land records using “Silver Cliff,” “Kate,” “Passiflora,” etc. as keywords. If they have GIS parcel maps, overlay the lode claims to find parcel IDs.
• If claims are patented, deeds should show the recorded owner. For unpatented claims, filings may show claimants.
2. BLM Claim Records
• If any lode claims are unpatented or on federal land, the BLM should have filings, including claimant names. Use the BLM LMS or whichever system Colorado uses (sometimes state-delegated).
3. Viscount Mining Disclosures / SEDAR / TSX-Ventures Filings
• Their NI 43-101 resource report and their most recent Annual Information Forms or corporate reports should have maps, list of claim boundaries, possibly schedules of claims, maybe even contacts of vendors.
4. Geologic / Mining Survey Data
• Colorado DRMS (Division of Reclamation, Mining & Safety) holds historic mine records that may include ownership, documents, maps. USGS MRDS might have older owner names which you can trace.
5. Legal / Broker / Title Search
• Use a mining lawyer or title company to pull title abstracts for specific parcels (once parcel IDs are known).
• Broker listings (if any claim or lease is offered), property listing services might have contact info.
Process to Find Mine / Claim Owners
Step 1 – Identify the Project Clearly
• Get the name(s): many mines have multiple names (Kate = Kate Deposit, Kate Silver Resource).
• Get the location: county, township/range, GPS coordinates if possible.
• Cross-check names with historic mining records (Western Mining History, USGS MRDS, The Diggings, local histories).
⸻
Step 2 – Determine Land / Claim Type
• Patented claim = private land, recorded at county recorder/assessor’s office.
• Unpatented claim = federal land, administered by the BLM.
This split determines which database you need to use.
⸻
Step 3 – Search Official Databases
• BLM MLRS (Mining Claim Records) → lists all active unpatented claims, claim names, claimant names, dates filed, serial numbers.
• County Recorder / Clerk / Assessor → deeded land, patented claims, leases, royalties, mortgages.
• Colorado DRMS (Division of Reclamation, Mining & Safety) → mine permits, reclamation bonds, operator names, compliance history.
• USGS MRDS (Mineral Resources Data System) → historical info, commodities, past owners/operators.
⸻
Step 4 – Collect Ownership / Control Information
• Names of individuals, companies, or trusts on record.
• For companies: cross-check with Secretary of State (Colorado SOS) to get business registration, agent, and mailing address.
• For listed companies: check SEDAR/SEC/EDGAR filings for NI 43-101 or 10-K/10-Q reports → often list claim agreements and vendor names.
⸻
Step 5 – Trace Historic Ownership / Vendors
• Many projects have a chain of ownership (e.g., Kate was once held by Tenneco, then CoCa, then Viscount).
• Look for option agreements, leases, royalties in company press releases or technical reports.
• Historic owner names may still be tied into current deals (royalty holders, surface rights owners).
⸻
Step 6 – Verify Contact Details
• For individuals: county assessor/tax records often list mailing addresses.
• For companies: Secretary of State filings include mailing addresses and registered agent.
• For public companies: investor relations email/phone on their website.
⸻
Step 7 – Build the Owner Dossier
Each project should have a standardized summary:
• Project Name / Alias Names
• Location (County, GPS, Township/Range)
• Deposit Type / Commodity
• Current Claim Holder / Owner (company or individual)
• Ownership Details (patented/unpatented, leases, NSRs, royalties)
• Historic Owners / Operators
• Contact Information (mailing address, phone, email, registered agent)
• Source Links (BLM, DRMS, County, USGS, company filings)
⸻
Repeatability
This framework can be applied to:
• Known historic districts (e.g. Georgetown, Leadville, San Juan).
• Individual named mines (from MRDS/WesternMiningHistory).
• New exploration projects (junior company press releases).
• Claims for sale (Juniorminers.com, Minelistings, Land Matters).
⸻
So in short:
1. Identify mine + location.
2. Determine claim type (patented vs unpatented).
3. Check BLM, County, DRMS, USGS.
4. Pull names → verify through Secretary of State.
5. Gather contact details.
6. Build an “owner dossier.”
• Target: Silver, copper, gold, and rare earth element deposits, past-producing silver mines, or silver-rich polymetallic projects (Ag-Cu-Au) in Colorado. Areas like Silver Cliff (Custer County), La Plata (Durango area), or even smaller claim sets in Park County are all on the radar.
