Background Information Document (BID)

This Background Information Document (BID) provides information to assist stakeholders to participate in the Environment Impact Assessment (EIA) and environmental authorization process for the proposed Gold Mining Project At Randegi District, Birnin Gwari L.G.A of Kaduna State by Sandcrete Engineering Nig. Ltd (Sandcrete)

What is the EIA About?

Basically, the EIA is the process of identifying, predicting, evaluating and mitigating the bio physical, social and other relevant effects of Sandcrete proposed project prior to major decisions being taken and commitments made.

The general objective of this EIA is to assess the potential environmental and social impacts associated with the planning, construction, operation and decommissioning phases of the proposed Project. Sandcrete has not yet commenced mining, and are currently carrying out exploration activities to assess the financial feasibility of the proposed mine. Exploration entails field investigations involving drilling, sampling, mapping of the target mineral resource, pilot testing, process development and ancillary investigations to determine the overall economic feasibility of the proposed Project.

In compliance with Nigeria regulatory bodies statutory provisions and in accordance with the EIA Act 86 of 1992, the project-proponent has commissioned Richflood International Limited, being a Nigerian based environmental consultant, to conduct an Environmental Impact Assessment (EIA) for the proposed Gold Exploration and Mining Project (The Project)


Sandcrete Engineering Nig. Ltd is a wholly Nigerian company with offices across West Africa and the U.S. The company general interest is solid minerals exploration and mining. The company currently specializes in the exploration and production of high quality quarry materials (granite slabs & chippings) and precious stones (gold and gemstones) for the Nigerian, African and international markets.

Sandcrete currently operates three (3) quarry sites in the southwestern part of Nigeria, and three additional gold and gemstones mines in northern Nigeria. The company is licensed “Mineral Buying Centre” in Nigeria.

Sandcrete currently holds an Exploration License EL 022424. Number of units 323 CU 22424EL equivalent to an area of 46.4 km2 bearing the gold mineralized zone.

Objectives of the EIA

The objectives of the EIA for the project site are to:
Provide information and evidence required for developing an

Environmental Impact Statement for the project site;

  •  Establish baseline information for the project site.
  •  Identify associated/potential impacts of the project in the area;
  •  Recommend preventive, mitigative and control measures for the identifiedpotential/associated adverse impacts of the project; and

Develop an effective Environmental Management Plan (EMP) for the lifetime of the project.

Project Overview

The First phase development of Sandcrete Engineering Gold field in Binin-Gwari area of Kaduna is mainly by Alluvial (Placer) mining (Sandcrete 2015). This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. This process uses the density of gold and the force of gravity to separate gold particles from other sedimentary deposits.

Phase 1: Exploration Phase
It included core drilling, sampling and pilot testing of wells for potash deposits as well as other specialized studies, such as hydrogeological studies, in order to determine the feasibility of the proposed project. The mineral resource estimate derived is a major component in the evaluation of the overall economic feasibility of the proposed Project. The results of exploration drilling activities revealed the extensive source of the ore. As a result, the proposed Project have moved from exploration to pre-feasibility and feasibility phases.

Phase 2: Definitive Feasibility Study

In parallel to exploration activities, Sandcrete commissioned engineering works and planning (including the engineering scoping study and definitive feasibility study) and the EIA. These activities are currently underway and are being undertaken to determine how much it will cost to implement the proposed Project,

including the costs of implementation of social and environmental mitigation measures determined by the EIA.

Phase 3: Bridge Engineering Phase

The preparation phase after the feasibility and before the start of construction is known as the bridge engineering phase. During this phase project activities on critical path and components are identified and actively managed to ensure that its implementation does not affect the overall project programme. The bridge engineering activities are anticipated to start in February 2017.

Phase 4: Pre-Construction Phase

Pre-construction activities consists of the finalization of engineering studies, bridge engineering activities, the receipt of a mining license, finalization of agreements with the Host Community, securing Project finance and the anticipated EIA approval from the Federal Ministry of Environment (FMEnv).

Phase 5: Construction

Pending environmental approval of the EIA from the FMEnv and finalization of pre-construction activities, commencement of construction activities is scheduled for March 2017 and has a planned duration of approximately 15 months. Construction includes the installation of all Project related infrastructure, including the camps where the workers will be housed.

Phase 6: Operation

Operation of the mine is scheduled for commencement upon final installation of Project infrastructure, scheduled for June 2017. The expected lifespan of the mine is approximately 30 years for the concession. Overall Mining activities will include the mining and processing of gold ore.

Phase 7: Decommissioning and Closure

The decommissioning and closure phase will start when the gold deposit is fully exploited from the licensed area. Decommissioning and closure involves the dismantling of mine infrastructure and the rehabilitation of disturbed land amongst a range of other activities. At this phase, the Environmental Protection and Rehabilitation Programme approved by the Federal Ministry of Solid Minerals will be implemented.


Environmental Impact Indicators

The environmental impact indicators for the study are easily observable parameters that will indicate change/deviation, which can be used to monitor the various environmental components.

The primary Biophysical Indicators for the on-going impact assessment are the following:

  • Climate and meteorology;
  • Air quality;
  • Noise levels;
  • Groundwater;
  • Geology and geomorphology;
  • Soils and soil erosion;
  • Drainage patterns and flooding;
  • Unique physical features; and
