A desktop draft of the mine's EIA/ESG conformance — Ghana EPA (Act 490 / LI 1652) mapped against GISTM, IRMA, ICMM, IFC PS, ISSB S2, GRI 14 and TNFD, screened on Ghana-resolution spatial data — with an honest gap register of everything that still needs field data and a registered practitioner's sign-off.
This Snapshot screens Ahafo Gold Mine (Newmont Ghana Gold Ltd, Gold) against Ghanaian regulatory requirements and international responsible-mining frameworks. It consolidates land, water, tailings/flood, air and closure screening into one audit-ready draft and a transparent gap register.
● Screening data: LIVE — SafeGround + FloodGuard across 9 concession points, queried 2026-06-14. Findings marked ○ seed are illustrative (no live engine for that aspect).
Readiness = share of framework requirements with desktop/GIS evidence already in place; the remainder need primary data, consultation or sign-off (see the gap register, §6). It is a drafting-progress measure, not a compliance score.
18 requirements need primary data or professional sign-off and are flagged, not assumed conformant. This is decision-support for a registered EIA practitioner — not a substitute for an EIS, field surveys, stakeholder consultation or audit.

Gold sites carry large, long-dated closure liabilities: pit lakes, TSF capping and revegetation, waste-rock landform stabilisation. Resilicity's differentiator is a science-based progressive revegetation plan — native species selection, substrate amelioration and phytostabilisation of metal-bearing substrates — grounded in Aduse-Poku phytoremediation methodology. This is foregrounded as the reclamation & positive-legacy section.
| Species | Role in the reclamation plan |
|---|---|
| Chrysopogon zizanioides (vetiver) | Phytostabilisation of metal-bearing substrates; TSF-cap & slope erosion control |
| Terminalia superba (Ofram) | Fast native pioneer for forest-canopy re-establishment |
| Senna siamea | Hardy nurse / windbreak on waste-rock landforms |
| Leucaena leucocephala | Leguminous nurse; soil-nitrogen amelioration (manage invasiveness) |
| Ceiba pentandra | Emergent native tree; biodiversity & seed-dispersal anchor |
Order-of-magnitude screening estimate over ~150 ha of restored vegetation (~600 ha leaf area) using the Aduse-Poku deposition-velocity method (ScienceDirect 2024; Springer Urban Ecosystems 2025). Assumptions: Vd(NO₂)=0.0015 m/s, Vd(PM10)=0.002 m/s, LAI=4.0, effective annual fraction=0.5, ambient NO₂=12.0 µg/m³, PM10=45.0 µg/m³ over 150 ha restored. Calibrate with site leaf-area index, species-specific Vd and measured ambient concentrations before reporting.
