Site Assessment and Percolation Testing
BRG provide tailor-made services across the full geological spectrum structured to fit the needs of your project. Whether under the umbrella of Project Management or as standalone ventures, BRG are experienced in providing:
Geological Mapping and Structural Analysis
Mapping of strata, structure, geomorphology and identification of geohazards for site investigation and mineral exploration purposes.
Target Generation
Local and regional target generation in consultation with clients. Drilling programme design and implementation in consultation with drilling contractors. Optimisation of drilling methods through, for example, directional drilling to reduce costs for the client and improve accuracy in hitting targets.
Project Management and Supervision
On-site management and supervision of site work for engineering projects and drilling operations including trial pitting, slit trenching, shell & auger drilling, diamond coring and soil and water sampling. Liaising with sub-contractors, the public, local authorities and all other stakeholders on behalf of the client.
Drill Core and Soil Logging, Geotechnical Logging and Sampling to Industry Standards
Detailed logging of lithology, alteration, mineralisation (including grade estimation) and geotechnical properties to BS 5930:1999, Eurocode 7 and BS 14689-1:2003 standards. Soil and rock logging to BS 5930:1999 / Eurocode 7.
Sampling and Geochemical Analysis
Site specific design of sampling programme and recommendation of analytical method to be utilised in consultation with the client.
Survey of sample locations using GPS.
Scheduling and delivery of samples to a fully accredited laboratory.
QA/QC checks on the results.
Interpretation and modelling of the analytical results.
Sample Types and Methods
Outcrop sampling
Prospecting
Shallow soil and deep overburden sampling:
Augering of disturbed and undisturbed samples using hand auger or a
percussion drill (Pionjar / Cobra), along with supervising sub-contractors
to conduct rotary/shell and auger drilling and sampling programmes.
Geotechnical sampling
Surface and groundwater sampling
Gas and leachate sampling
Drill core sampling and splitting for assay analysis
Drill core groove sampling for lithogeochemical analysis
Gold panning
