30 Seconds of Info: Be sure to check the orientation of the cone splitter daily

This week's 30 Seconds of Info is from Ian Glacken - Director of Geology. Sampling Theory and Practice: Be sure to check the orientation of the cone splitter daily. While a cone splitter should and generally will give a matched (equiprobable) pair of field duplicates, the orientation of the splitter is all-important in determining this. The long axis of the splitter needs to be vertical and the widest part of the splitter, i.e. the join between the cone and the chute, needs to be horizontal. This should be checked daily with a magnetic clinometer. iglacken@snowdenoptiro.com

Optiro’s summary of the RSC Resource Reporting Intelligence for 24-30 April 2017.

Optiro's summary gives information about the 95 technical reports published during the week of the 24-30 April 2017. This summary details the type of report, the project locations and commodities, the ranking of the global consultancy groups as authors of the reports, and lists the 3 most significant drill intersections for the week, month and year to date.

30 Seconds of Info. Remember some sampling errors cannot be eliminated but they can be minimised.

In addition to the Fundamental Sampling Error, which is the subject of Gy’s theory and its derivations, the Grouping and Segregation Error (GSE) is a function of the size, nature and constitution of the particles, among other factors. The GSE certainly can be reduced through judicious practice, but there are circumstances where the GSE can swamp other errors – you need to be aware of these.

Spreadsheets aren’t databases! 30 Seconds of Info by Ian Glacken – Director of Geology.

This week's 30 Seconds of Info is from Ian Glacken - Optiro's Director of Geology. Spreadsheets aren’t databases! Spreadsheets are the cornerstone of reconciliation reporting and analysis but are not the best repositories for raw data. Any large spreadsheet which is not locked down is almost certain to have errors, and if this is the main storage area for the raw reconciliation data then there will be problems. Databases, whether through a production tracking system or a custom industrial-strength application, are no-brainers for storing raw reconciliation data. iglacken@snowdenoptiro.com
