ddi.analysisunita limited number of carefully drilled diamond drill-holes
ddi.cleanopsThe data was cleaned during the Citation Course in Geostatistics presented by Deutsch, C, V in Johannesburg, South Africa in August 2011. The comments, discussion, and inputs arising from the other 15 attendees, some of which are incorporated here, are acknowledged.

ddi.collmodeDonated by mining house from the course and use of there usual primary data collection This data was kindly provided by Gold Fields* , and is made up of a large number of underground chip samples together with a smaller number of underground and surface borehole samples. The data is of point support, and at each point a measurement of the reef’s channel width (measured in centimetres), gold grade (measured in grams per ton) and accumulation (measured in centimetre grams per ton) is given.
ddi.conditionsThere are commercial restrictions on the dataset and it cannot be used outside of the permission given by Rowland, T. R. in 2008, pers. comm., 11 August 2012
ddi.conditionsThe data rights are unclear and the data can only be viewed by those covered by the original agreement
ddi.dataaccsOnly the unlocated samples are available for the review , the rest of the data is held by the researchers for the use it was donated for for the Witwatersrand school of mining engineering.

ddi.methodThe real-life gold mining data that is used is from gold mines in the Witwatersrand Basin of South Africa and the copper mines of Zambia . It is generally difficult to extensively sample or drill out these deposits, as they lie deep underground.
