# USGS MRDS Mineral Occurrence Master (`nexgenwatch/usgs-mrds-occurrence-master`) Actor One structured occurrence record per USGS Mineral Resource Data System (MRDS) deposit β€” the source-native dep_id, deposit name, commodities, coordinates, and development status β€” filtered by commodity, development status, and/or bounding box. - **URL**: https://apify.com/nexgenwatch/usgs-mrds-occurrence-master.md - **Developed by:** [NexGen Watch](https://apify.com/nexgenwatch) (community) - **Categories:** Automation, Lead generation, Developer tools - **Stats:** 2 total users, 1 monthly users, 50.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing from $13.40 / 1,000 mrds occurrence records This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have. Learn more: https://docs.apify.com/actors/running/actors-in-store.md#pay-per-event ## What's an Apify Actor? An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README ## πŸ”” USGS MRDS Mineral Occurrence Master One structured **occurrence record per USGS Mineral Resource Data System (MRDS) deposit** β€” the source-native `dep_id`, deposit name, commodities, coordinates, and development status β€” filtered by commodity, development status, and/or bounding box. Built for exploration, minerals-supply, and research teams who need MRDS occurrences as clean, keyed, deduplicated facts. **Differentiation:** the usual MRDS tooling either scrapes the now robots-blocked `mrdata.usgs.gov` (`Disallow: /`) or dumps the entire 304,632-row table. This master serves the **same authoritative MRDS occurrence layer through the clean USGS ArcGIS door** (`energy.usgs.gov/arcgis`, no robots restriction), is **filter-scoped by contract** (a filter is mandatory β€” no unbounded pulls), deduplicates on `dep_id`, hard-caps at 2,500 per run, and stamps **an explicit staleness note on every record**. Output is one `usgs_mrds_occurrence` row per result; billing is pay-per-event, the value event being one mrds occurrence record (a $0.02 start fee per run, then $0.02 per mrds occurrence record). Source: energy.usgs.gov, mrdata.usgs.gov. No login, no API key and no CAPTCHA solving are involved: the source is read logged-out with an identified contact User-Agent. ### πŸ“Š Sample Output [![USGS MRDS Mineral Occurrence Master sample output β€” a table of real mrds occurrence record rows (dep_id, site_name, development_status, latitude) from run OUuhwweBsz8htqb9m on build 0.1.5](https://api.apify.com/v2/key-value-stores/80Y7h3rmVN5CWK7Mw/records/usgs-mrds-occurrence-master-sample)](https://apify.com/nexgenwatch/usgs-mrds-occurrence-master?fpr=2ayu9b) Real rows from run `OUuhwweBsz8htqb9m` on build 0.1.5 (2026-09-19), the same input as the Quick start below β€” every value is as the source published it (emails masked, long text shortened): | dep_id | site_name | development_status | latitude | longitude | record_url | |---|---|---|---|---|---| | 10000001 | Lookout Prospect | Occurrence | 55.05612000000008 | -132.14343999999994 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000001 | | 10000002 | Lucky Find Prospect | Occurrence | 55.52751000000006 | -132.68514 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000002 | | 10000003 | Mccullough Prospect | Occurrence | 55.97751000000005 | -132.99906 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000003 | | 10000004 | Lucky Jim Claim | Occurrence | 55.52195000000006 | -132.68652999999995 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000004 | | 10000005 | Matilda Occurrence | Occurrence | 55.145560000000046 | -132.05232999999998 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000005 | | 10000008 | Morning Star Prospect | Occurrence | 55.56362000000007 | -132.45041999999995 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000008 | | 10000009 | Monday Prospect | Occurrence | 55.50529000000006 | -132.63236999999998 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000009 | | 10000010 | Miller Brothers Claim | Occurrence | 55.223340000000064 | -132.63512999999995 | https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000010 | The run finished with the status message: `NORMAL: 50 unique rows (0 duplicates collapsed). billable=50` ### βœ… What you get Each row is flat JSON with these fields (from the dataset schema and the sample run;

USGS ceased systematic MRDS maintenance around 2011. Every record carries `staleness_note` so no buyer mistakes an archival occurrence for a current one. ### βš™οΈ Sample inputs **1. Quick start β€” the Store example (this is what the sample above came from)** ```json { "commodities": [ "AU" ], "maxRecords": 50 } ``` The sample run charged exactly: 2 Γ— $0.02 apify-actor-start + 50 Γ— $0.02 occurrence_record = **$1.04** on the Free tier β€” every delivered row was billed. **2. A smaller, narrowed run** ```json { "commodities": [ "AU" ], "maxRecords": 5 } ``` Caps the run at 5 rows β€” about $0.12 on the Free tier ($0.02 start + 5 Γ— $0.02). **3. A full-size run** ```json { "commodities": [ "AU" ], "maxRecords": 2500 } ``` Up to 2500 rows (the schema default for `maxRecords`) β€” about $50.02 on the Free tier ($0.02 start + 2500 Γ— $0.02) if the source has that many. **4. A filtered run** ```json { "commodities": [ "AU" ], "maxRecords": 50, "fieldMatch": { "site_name": "Lookout Prospect" } } ``` Keeps only rows whose `site_name` contains `Lookout Prospect` (a value from the sample run above), matched case-insensitively after the source is read and **before** the `maxRecords` cap, so the cap counts matches and only delivered matches are billed. `searchText` does the same across every column. Zero matches end the run as `EMPTY_SELECTION` with no row charged β€” if the source has moved on since that sample run, pick a value you see in your own first run. The source is still read in full β€” this narrows what you receive and pay for, not what the source serves. ### 🧾 JSON sample record One real record from run `OUuhwweBsz8htqb9m`, exactly as it lands in the dataset (emails masked, long text shortened): ```json { "record_type": "usgs_mrds_occurrence", "dep_id": "10000001", "site_name": "Lookout Prospect", "commodities": "CU AU AG", "development_status": "Occurrence", "latitude": 55.05612000000008, "longitude": -132.14343999999994, "grade": "C", "record_url": "https://mrdata.usgs.gov/mrds/show-mrds.php?dep_id=10000001", "staleness_note": "MRDS is a static legacy compilation; USGS ceased systematic MRDS maintenance circa 2011. This record reflects the archival snapshot, not current site status.", "source": "usgs-mrds-occurrence-master", "release_date": null, "source_url": "https://energy.usgs.gov/arcgis/rest/services/MRData/Mineral_Resource_Data_System/MapServer/3", "observed_at": "2026-09-19T00:15:22Z", "license": "USGS Mineral Resource Data System (MRDS) β€” U.S. Government public domain.", "attribution": "U.S. Geological Survey, Mineral Resource Data System (https://mrdata.usgs.gov/mrds/)" } ``` ### πŸ”§ How it works **Source.** The actor reads energy.usgs.gov, mrdata.usgs.gov β€” endpoints: `https://energy.usgs.gov/arcgis/rest/services/MRData/`, `https://energy.usgs.gov/arcgis/rest/services/MRData/Mineral_Resource_Data_System/MapServer/3/query`, `https://mrdata.usgs.gov/mrds/`. Public pages and feeds only; nothing behind a login. **Transport.** Plain HTTPS from the Apify platform, no proxy. robots.txt is read first and a disallowed path is never fetched. Every request carries an identified contact User-Agent. Pacing: `CRAWL_DELAY`=0.0. **Terminal states.** A run ends NORMAL, CAPPED (your cap was reached), PARTIAL (something was withheld and the message says what), GENUINE_EMPTY (the source was read and truly had nothing in scope) or BLOCKED (the source refused or changed shape β€” the run FAILS loud and bills nothing). A zero-row run is never reported as a silent success. **Charging.** Each mrds occurrence record is charged at the moment it is pushed (`occurrence_record`); a row that fails to charge is not delivered, so the dataset count always equals the charged count. **πŸ”§ How it works** **Source** The public USGS ArcGIS REST layer `energy.usgs.gov/arcgis/rest/services/MRData/Mineral_Resource_Data_System/MapServer/3` β€” bounded `resultOffset` paging, honest UA, robots honoured at run time (the host publishes no `robots.txt`). **What this does NOT report** **Never ownership, production, or current operating status.** MRDS layer 3 carries only a static development *classification* (`development_status`, e.g. Occurrence/Prospect/Producer), reported as provenance. Nothing about who owns, operates, or produces at a site β€” or any production tonnage/volume β€” is derived or emitted. **Licence** USGS MRDS is **U.S. Government public domain**. Every record carries `license` and `attribution` (*U.S. Geological Survey, Mineral Resource Data System*). **What is not done.** No login, no cookie or CAPTCHA bypass, no private or personal-account data, no browser automation. ### πŸ’° Pricing example | Event | Free | Bronze | Silver | Gold | |---|---|---|---|---| | Actor Start (`apify-actor-start`) | $0.02 | $0.02 | $0.02 | $0.02 | | MRDS occurrence record (`occurrence_record`) | $0.02 | $0.018 | $0.016 | $0.0134 | Worked at the live Free-tier price: - 8 mrds occurrence records: $0.02 start + 8 Γ— $0.02 = **$0.18** - 25 mrds occurrence records: $0.02 start + 25 Γ— $0.02 = **$0.52** - 2500 mrds occurrence records: $0.02 start + 2500 Γ— $0.02 = **$50.02** A run that delivers zero rows charges the $0.02 start fee only. A BLOCKED run (source refused) fails loud and charges no value event. The start fee is charged once per GB of run memory; the default run memory is 4096 MB. Yield on the sample run: `NORMAL: 50 unique rows (0 duplicates collapsed). billable=50`. `maxRecords` is a hard ceiling on what is delivered and billed, never a target. ### βš–οΈ Legal & ToS This actor reads public, logged-out pages and feeds published by energy.usgs.gov, mrdata.usgs.gov. It collects only what the source publishes to any visitor, keeps to the source's robots rules (checked on every run), identifies itself with a contact User-Agent, and does not access accounts, private data or anything behind authentication. Use the output in line with the source's terms and your local law; the intended use is B2B research and monitoring. ### ❓ FAQ **Q: Do I need an API key or a login?**\ A: No. The source (energy.usgs.gov, mrdata.usgs.gov) is read logged-out; the input schema has no key field and the actor carries no secrets. **Q: Why did my run return 0 rows?**\ A: Read the run's status message. GENUINE_EMPTY means the source was read and had nothing in scope for your input; BLOCKED means the source refused and the run failed without billing a value event β€” retry later or narrow the input. A zero-row run bills the start fee only. **Q: How many rows can one run return?**\ A: Up to `maxRecords` (default 2500). Raise the cap for a bigger run; you pay per delivered row. **Q: How fresh is the data?**\ A: Every run reads the source live at run time; nothing is cached between runs. Put it on a schedule for a continuous feed. **Q: What formats can I export?**\ A: The dataset downloads as JSON, CSV, Excel, XML or RSS from the run's Dataset tab or the Apify API, and any run can push to a webhook or integration. **Q: How is this different from the other NexGen Watch actors actors?**\ A: Same output shape and billing model; this one covers energy.usgs.gov, mrdata.usgs.gov. The siblings under **Related Actors** cover the other sources or slices β€” run several on one schedule for a combined feed. **Q: Are there rate limits?**\ A: The actor paces itself against the source (`CRAWL_DELAY`=0.0) and honours its robots rules; there is no per-buyer limit beyond your Apify plan's concurrency. ### πŸ†˜ Troubleshooting - **Run FAILED with BLOCKED** β†’ the source refused the request or changed its page shape β†’ nothing was billed beyond the start fee; retry after a while, and if it persists open an Issue with the run id. - **Status says CAPPED** β†’ your cap (`maxRecords`) was reached β†’ raise it for a bigger run. - **Input validation error on start** β†’ a field is outside the schema's allowed values β†’ start from the Quick start block and change one field at a time. - **Run TIMED-OUT** β†’ a very wide request on a slow day β†’ raise the run timeout in Run options or narrow the input; what was delivered before the timeout is still in the dataset. ### πŸ”— Related Actors - [USDA FDC Product Update Ledger](https://apify.com/nexgenwatch/usda-fdc-product-update-ledger?fpr=2ayu9b) β€” One food_update_record per entry in USDA FoodData Central's own product update log β€” the FDC id, the product description, and the last_updated date,… - [USDA FNDDS Ingredient-Nutrient Matrix](https://apify.com/nexgenwatch/usda-fndds-ingredient-nutrient-matrix?fpr=2ayu9b) β€” One fndds_nutrient_record per row of USDA FoodData Central's fndds_ingredient_nutrient_value table β€” a single nutrient value for an FNDDS ingredient… - [USGS Earthquake Events Scraper](https://apify.com/nexgenwatch/usgs-earthquake-event-feed?fpr=2ayu9b) β€” Scrape USGS earthquake events (FDSN): magnitude, location, depth, time and event ID.

Open it from the **Issues** tab β€” every one is read. # Actor input Schema ## `commodities` (type: `array`): MRDS commodity codes to match, e.g. \["AU","CU"] (gold, copper). One filter (commodities / devStatus / bbox) is REQUIRED β€” the 304,632-feature layer is never pulled unbounded. ## `devStatus` (type: `string`): Exact MRDS development classification, e.g. Occurrence, Prospect, Producer, Past Producer. Static classification only β€” not current operating status. ## `bbox` (type: `array`): Spatial filter as lon/lat envelope, e.g. \[-133,55,-131,56]. ## `maxRecords` (type: `integer`): Max occurrence records delivered (buyer bound; one charge per delivered record). Hard-capped at 2500. ## `userAgent` (type: `string`): Override the transparent crawler UA. ## `searchText` (type: `string`): Optional. Keep only rows where any field contains this text (case-insensitive, substring). Applied after the source is read and BEFORE the maxRecords cap, so the cap counts matches and only delivered matches are billed. Zero matches = EMPTY_SELECTION, nothing charged beyond the start fee. ## `fieldMatch` (type: `object`): Optional. {"column": "text"} keeps rows whose named output column contains the text (case-insensitive); a list of texts means any of them; several columns must all match. Column names are the dataset fields shown in the sample output. Applied BEFORE the maxRecords cap and before billing. ## Actor input object example ```json { "commodities": [ "AU" ], "bbox": [], "maxRecords": 50 } ``` # Actor output Schema ## `results` (type: `string`): No description # API You can run this Actor programmatically using our API.
