Obsidian’s experience in mineral resource compilation, estimation and reporting covers a diverse range of commodities that includes gold, silver, molybdenum, iron ore, titanium, vanadium, platinum group elements, chrome, lead, zinc, copper, phosphate rock, industrial minerals, rare earth elements and diamonds.
Our service offering ranges from advising on mineral resource delineation projects to due diligence exercises including mineral resource audits.
Although work is tailored to each specific project, our approach typically includes;
- Database management (MS Access of SQL Server) including data validation and data quality assessment
- 2D and/or 3D modelling to delineate geological and/or mineralization models
- Statistical and geostatistical analyses including variography
- Mineral Resource Classification and Reporting according to international guidelines including NI 43-101, SAMREC and JORC.
This is generally done using the GEMS general mine planning software from Geovia and LeapFrog Geo from ARANZ.
