Minerals, tailings and land use — one anchored report

QA UI Lignite 47987 — Planning Summary (Konya) What satellite data shows (measured) Live satellite monitoring confirms land cover over 10.0 km²: mostly bare ground (67.0%), with mine (11.7%), vegetation (13.7%), urban (5.8%), water (1.8%). Vegetation has declined 4.2 points over 5 years — a real, observed trend. Current buffer to settlement is 2.0 km, below the recommended 4.3 km (not compliant). What is modelled (SIMULATED spectral indices) Mineral composition (lignite 53.3%, kaolinite 16.9%, pyrite/arsenopyrite 14.2%, gypsum 15.6%) and ore grade (2311 kcal/kg) are derived from spectral modelling, not direct lab assay — treat as indicative. Acid drainage risk is moderate (36.8), pH proxy 5.7 (mildly acidic), jarosite signal present (0.262), suggesting active sulfide oxidation. Modelled seepage path toward Beyşehir Lake (79.3 km) has an estimated travel time of ~86 years — low near-term risk but worth tracking. Recommendations - Zoning: No new residential within 4.3 km buffer; permit only industrial/green-belt use. - Dust control: Sealed haul roads and suppression systems (dust index 54.3 is elevated). - Rehabilitation: Revegetate at least 3.5% of footprint annually, prioritizing bare zones. - Monitoring: Quarterly hyperspectral surveys (anchored baseline) tracking pH, jarosite, and vegetation recovery. Overall grade: B — manageable risk with active mitigation. Research-grade analysis — verify with field sampling before regulatory decisions.
