# Claim/source table — Philippine Sea gold video

| Topic | Video/source evidence | GoldNotes treatment |
|---|---|---|
| Underwater/compressor gold mining | Video shows and captions describe miners working under the ocean floor using DIY rigs, hoses and beach compressors. | Treated as video evidence for the practice shown, not as a quantified estimate of national production. |
| Philippines ASGM scale | planetGOLD states the Philippines has an estimated 500,000 ASGM miners in more than 40 of 81 provinces and that 70% of national gold is attributed to ASGM. | Used to place the video in national artisanal/small-scale gold context. |
| Mercury exposure | Video captions describe mercury use in processing; planetGOLD says many ASGM miners use mercury and that it exposes miners/families/communities and contaminates soil/crops/oceans/fish. WHO states mercury exposure can cause serious health problems and affect nervous, digestive and immune systems, lungs/kidneys/skin/eyes. | Treated as a major health/environment/supply-chain risk, not a valuation metric. |
| Investor relevance | Informal gold can enter broader supply chains, while formalization/mercury reduction programs may change cost, traceability and ESG expectations. | Investors should ask producers/refiners/royalty companies how supply is sourced, traced and audited. |
