1. ABERTURA ACIONADA POR PAINPOINT

Are your Lagos quarry operations constrained by inconsistent material quality, unpredictable production rates, and escalating operational costs? In the competitive Lagos construction market, suboptimal quarry sites directly impact your bottom line through excessive overburden removal, high waste ratios from poor rock fragmentation, and frequent equipment wear from abrasive, unsorted feed. These challenges lead to project delays and compromised aggregate specifications. How can you ensure a consistent, highyield supply of premium granite or limestone to meet Lagos's infrastructure demands? The solution begins with the strategic identification and development of High Quality Quarry Sites in Lagos, enabled by precise geological assessment and modern extraction planning.

2. VISÃO GERAL DO PRODUTO

This service provides comprehensive geological evaluation and feasibility analysis for identifying High Quality Quarry Sites in Lagos. The operational workflow transforms raw land data into a viable extraction plan:
1. Desktop Study & Geological Mapping: Analysis of existing geological surveys, satellite imagery, and mineral rights data to identify promising zones.
2. Subsurface Investigation: Core drilling, seismic refraction surveys, and sample collection to determine rock composition, dureza (UCS), fracture density, e profundidade de sobrecarga.
3. Reserve Modeling & Pit Planning: 3D modeling of the deposit to calculate proven reserves, define optimal pit geometry, and plan bench design.
4. Qualidade & Process Analysis: Laboratory testing of aggregate samples for crushability, resistência à abrasão (Los Angeles test), soundness, and gradation.
5. Feasibility Reporting: Delivery of a technical report detailing extractable volume, product quality forecasts, recommended processing flow, and preliminary ROI projections.

Application scope includes greenfield site identification for granite, calcário, and laterite deposits within a 150km radius of Lagos. A key limitation is that this service provides the data blueprint; actual site development requires subsequent investment in land acquisition, permitting, and plant installation.
