14.3.4 Mine Development Data Verification
In 2008, Kinross developed additional data verification procedures to support mine
development.
Data verification begins in the field and office where the responsible geologist checks
his paper forms or computer logs before passing them to the data entry staff. The core
data collector checks data entry real-time with typical built-in data validation settings
available to database utilities.
Keyboard data entry from paper forms passes directly into the SQL database subject
to validation ranges. Laboratory data are imported electronically and must match
prepared tables and references to pass the importation process. Standards related to
each sample batch received must pass established control limits before importation is
allowed.
The geologists are responsible for graphic checks of all assay data on drill hole plans
and sections, face assay plans, and trench maps. ODBC links from Micromine to the
database facilitate rapid and daily assay and lithology code checking. Many of the
underground face data are also migrated to Autocad where geologists scrutinize both
lithology and assay data.
14.4 Comment on Section 14
The process of data verification for the Project has been performed by Kinross and
Bema personnel and external consultancies contracted by those companies.
The QP, who relies upon this work, has reviewed the reports and is of the opinion that
the data verification programs undertaken on the data collected from the Project
adequately support the geological interpretations and the analytical and database
quality, and therefore support the use of the data in Mineral Resource and Mineral
Reserve estimation, and in mine planning, based on the following:
• No sample biases were identified from the QA/QC programs undertaken by Bema;
• Sample data collected adequately reflect deposit dimensions, true widths of
mineralization, and the style of deposit;
• Analyses completed by external laboratories confirm the gold and silver tenor
reported by the internal Kupol laboratory;
• An internal Bema review of the database was performed in support of the 2005
feasibility study. No significant problems with the database, sampling protocols,
flowsheets, check analysis program, or data storage were noted;
