LodeLeaf
Elements, Rights & Maps
Free · In‑App Purchases
Meet the redesigned Tools workspace: 20 permanent local calculators, research exports, chemistry helpers and study tools, available separately or together.
LodeLeaf organizes element data, public mineral-occurrence records, geographic coordinates, public mineral rights, and mining contracts in one focused reference workflow.
TOOLS
Open Tools for 20 local-first workflows: grade and contained-metal conversion; cutoff-grade, distance and coordinate calculations; formula weight, molar mass, equation balancing, oxidation states, stoichiometry and unit conversion; record filters, table and geographic exports, citations and holder summaries; plus quizzes, spaced repetition, a quiz builder and a learning dashboard.
Each tool is a permanent one-time purchase, or can be unlocked together with All Tools Lifetime. Prices are supplied by your platform store. Purchases restore through your store account; no LodeLeaf account or cloud service is required.
Search all 118 elements in Overview, then open Distribution to inspect historical USGS MRDS records, curated references, country or area, coordinates, and original sources. LodeLeaf transforms the official USGS bulk file into a monthly static Cloudflare mirror; curated records remain visible if the mirror is unavailable.
For instruments published by Gold API, LodeLeaf shows public market references for gold, silver, platinum, palladium, and copper with source and timestamp. Other elements display an explicit unavailable state instead of an invented price.
Rights & Deals includes:
- Company-held mineral-right records from British Columbia
- Western Australia Mining Tenements (DMIRS-003) company records
- Published mining contracts from ResourceContracts.org
- Official information and registration links for related mining and materials events
Registry changes are not labelled as sales. Verify title, holder, consideration, effective date, and legal status with the original source. The rights mirror excludes street addresses, client identifiers, and non-corporate holder names.
Data licences:
- British Columbia mineral tenure: Open Government Licence - British Columbia
- Western Australia DMIRS-003: CC BY 4.0
- ResourceContracts.org contract metadata: CC BY-SA 4.0
LodeLeaf supports 20 interface languages and provides source, licence, privacy, land-access, regulated-trade, and support information in Settings.
MRDS is a historical reference database and has not been systematically updated since 2011. A map point or registry record grants no access, collecting, prospecting, mining, ownership, or trading rights. Market references are not purchase offers, valuations, or investment advice.
