🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟡preview_exploration_map(map_type, title, subtitle, jurisdiction, search, ...)

Create a branded mineral exploration map from public registry claims and return a shareable URL. Provide at least one of search, location or claim_numbers. For a specific project, search its claims first and pass exact claim_numbers. Supply published facts and branding when known; never invent ownership, targets, grades or coordinates. Supports separate neighbouring claims, a project callout, locator inset, and map basemap selection. Drill and NI 43-101 layouts require user-supplied data or qualified review; this tool does not generate drill results. Free use allows 10 previews per hour; allowance in the result reports how many remain.

🟢search_mineral_claims(jurisdiction, search_type, query, bbox, limit)

Search public mineral-claim registries by holder, exact claim number, claim name, or geographic bounding box; provide query, bbox, or both. Claim-name search is available for British Columbia and US BLM jurisdictions. Returns claim number as a string, name, holder, status, expiry, area and centroid when the registry supplies them. Cluster results geographically before selecting a specific project. Results are informational, not a legal title opinion or survey.
