1. PAINPOINT DRIVEN OPENING

Establishing and operating a quarry site in Lagos presents distinct regulatory and operational hurdles. Navigating the complex approval process with the Federal Ministry of Mines and Steel Development (FMMSD) and other agencies is just the first step. Once operational, sites face persistent challenges: inconsistent aggregate quality from variable local geology leading to product rejection, excessive downtime from equipment unsuitable for lateritic soils and hard rock transitions, and severe pressure to control operational costs amidst rising fuel prices and logistics constraints. Are you managing site planning delays due to uncertain mineral deposit assessments? Are you experiencing profit erosion from low plant availability and high maintenance cycles? The foundation of a profitable, compliant operation begins with a professionally engineered design service tailored specifically for FDA approved quarry sites in Lagos.

2. PRODUCT OVERVIEW

Our service is a comprehensive Quarry Site Design and Engineering Package for greenfield or brownfield expansions targeting limestone, granite, or laterite extraction in SouthWest Nigeria. This is not just a site plan; it is an integrated operational blueprint. The workflow begins with (1) Geotechnical & Reserve Analysis of your licensed acreage to precisely define ore body geometry and quality. This feeds into (2) Process Flow & Plant Layout Design, optimizing material movement from face to crusher to stockpile. The third phase (3) Infrastructure & Compliance Engineering details haul roads, drainage, sedimentation ponds, and power distribution to meet all regulatory stipulations for an FDA approved quarry site. This service is applicable for operations targeting 100 1,000+ TPH capacity but requires clientprovided core drilling data and a valid mining lease as foundational inputs.

3. CORE FEATURES

Mineral Deposit Modeling | Technical Basis: 3D block modeling from assay data | Operational Benefit: Predicts feed grade variability and enables precise bench planning for consistent plant feed | ROI Impact: Minimizes processing of subgrade material, directly improving yield by 815%

Haul Road Optimization | Technical Basis: Civil engineering design for rolling resistance minimization | Operational Benefit: Reduces cycle times for haul trucks and lowers fuel consumption per ton hauled | ROI Impact: Field data shows a 1220% reduction in fleet fuel costs over the life of the mine.

Water Management System Design | Technical Basis: Hydrological modeling for peak rainfall events | Operational Benefit: Ensures operational continuity during wet season and prevents costly shutdowns from flooding or regulatory noncompliance | ROI Impact: Avoids potential fines and revenue loss from seasonal downtime.

Dust Suppression Integration | Technical Basis: Pointsource suppression design at crusher feeds, screens, and transfer points | Operational Benefit: Creates a safer working environment and maintains community relations, critical for sustained operation near populated areas in Lagos/Ogun states | ROI Impact: Reduces healthrelated absenteeism and preempts communityled operational disruptions.

Modular Plant Layout | Technical Basis: Scalable, phased equipment placement on stable foundations | Operational Benefit: Allows for costeffective future capacity expansion with minimal disruption to ongoing production | ROI Impact: Protects capital by deferring major expenditure until market demand is confirmed.

6. APPLICATION SCENARIOS

Granite Quarry Expansion in Ogun State

Challenge A longestablished quarry faced depletion of its initial pit. The operator needed to expand into adjacent leased land while maintaining uninterrupted production from the existing plant.
Solution Our design service conducted a new reserve assessment on the new acreage and engineered a phased haul road network that connected new faces directly into the existing primary crusher feed hopper.
Results The operator avoided a complete plant relocation. The expansion was executed without stopping existing production lines within one fiscal year.

New Greenfield Limestone Quarry

Challenge An investor with an FDAapproved mining lease required a bankable feasibility study layout that would secure financing.
Solution We provided a complete quarry site design package focused on minimizing initial capex through modular staging while demonstrating clear pathways to fullscale production.
Results The detailed engineering reports satisfied lender requirements. The optimized layout reduced estimated initial earthworks costs by approximately NGN45 million.

8. FAQ

Q1 Is this design service compatible with existing equipment we already own?
A1 Yes. A key phase of our work involves auditing your current asset list—crushers excavators etc.—and integrating them into the new layout ensuring optimal utilization before recommending any new capital expenditure

Q2 How does this address delays in obtaining final blasting permits?
A2 Our designs include standardized explosive magazine location plans blast vibration prediction models based on local geology which form critical components of the required permit applications reducing backandforth with regulators

Q3 What are typical payment terms?
A3 Projects are structured on milestone payments aligned with key deliverables Reserve Report approval Preliminary Layout approval Final Drawing issuance

Q4 Can you assist with contractor selection after design?
A4 We can provide technical specifications tender documents as part of our package but we maintain neutrality in contractor selection

Q5 How long before we see an efficiency gain postimplementation?
A5 Primary gains such as reduced haulage fuel consumption are immediate upon using new roads Secondary gains like higher plant availability manifest within first quarter as material flow bottlenecks are eliminated
