This Open File was created to serve as a handy hard-copy reference for anyone
interested in British Columbia’s rich mineral endowment. This publication will appeal
to a wide variety of local and international users, including government agencies, mining
and exploration companies, researchers, and the public.This 190-page
publication documents the known reserves and resources of 824 mineral deposits from the
MINFILE database. The reserves/resources are reported in tonnes and grade of commodities.
The MINFILE Reserves/Resources Inventory reflects the status of the database as of January
2000. Data for each deposit include name, MINFILE number, geographic location, NTS map,
status, mining division, deposit type, zone name, year, reference, comments, tonnage,
category, grade and commodity. Various reports and sorted tables are included: a Commodity
Legend, a sample Master Report, an Alphabetical Index, a MINFILE Number Index, a table of
Mineral Deposit Profiles, and a Deposit Type Index. Deposit type is based on the British
Columbia Mineral Deposit Profiles of the Geological Survey Branch.
The Reserve category is used only for an inventory in an operating mine or a
mine near production. Ore reserves are reported as Proven, Probable and Possible. The
Resource category is used for all other inventories. Resources are reported as Measured,
Indicated and Inferred. A combination of categories is reported as Combined.
Qualitative and quantitative reporting of deposit economics are affected by
several parameters. Some of these include the variable reliability of reporting,
differences in interpretation of terms, and changing economic conditions. Reserves and
resources are not calculated by Ministry personnel but are quoted from referenced industry
sources and/or publications. Due to differences in identifying categories in the data
sources, Ministry personnel may occasionally need to interpret the category that the
figures belong to. The reader should refer to the original data for detailed information.
Effort has been made to ensure that the contents of this publication are as
accurate as possible. The reader is encouraged to send comments or corrections to any
member of the MINFILE Project.
