Glossary
The following is a glossary of terms
used throughout the site:
1021105 Ontario
1021105 Ontario Corp., a predecessor company to Kinross Gold
Corporation.
Amax
Amax Gold Inc.
Breccia
A rock dominated with angular fragments within a finer-grained
matrix.
CMP
CMP Resources Ltd., a predecessor company to Kinross Gold

Carbon-in-leach
A recovery process in which a slurry of gold ore, carbon
granules and cyanide are mixed together. The cyanide dissolves
the gold content and the gold is absorbed on the carbon; the
carbon is subsequently separated from the slurry for further
gold removal.
Carbon-in-pulp
Similar to carbon-in-leach process, but initially the slurry is
subjected to cyanide leaching in separate tanks followed by
carbon-in-pulp. Carbon-in-leach is a simultaneous process.
Cyanidation
A method of extracting gold or silver by dissolving it in a weak
cyanide solution.
Dilution
The effect of waste or low-grade ore being included unavoidably
in the mined ore, lowering the recovered grade.
Doré
Unrefined gold and silver bullion bars, which will be further,
refined to almost pure metal.
FGC

Grade
The amount of valuable metal in each tonne of ore, expressed as
grams per tonne for precious metals.
Cut-off grade - is the minimum metal grade at which a tonne of
rock can be processed on an economic basis.
Recovered grade - is actual metal realized by the metallurgical
process and treatment of ore, based on actual experience or
laboratory testing.
Reserve grade - is the estimated mass weighted average metal
content of an ore body, based on reserve calculations.
Heap leaching
A process whereby gold is extracted by “heaping” broken ore on
sloping impermeable pads and repeatedly spraying the heaps with
a weak cyanide solution which dissolves the gold content. The
gold-laden solution is collected for gold recovery.
Hectares
One hectare = 2.47 acres.
Kilometer
One kilometer = 0.62 miles.
Kinam
Kinam Gold Inc., formerly Amax Gold Inc., a Delaware corporation
and an indirectly wholly owned subsidiary of Kinross Gold
Corporation.
Kinam Series B Preferred Shares
Convertible preferred shares of Kinam as described fully in the
notes to the Consolidated Financial Statements.
Kinross
Kinross Gold Corporation, an Ontario Corporation.
Kinross USA
Kinross Gold U.S.A., Inc., a Nevada corporation and a 100%
wholly owned subsidiary of Kinross Gold Corporation.
Meter
One meter = 3.28 feet.
Mill
A plant where ore is ground fine and undergoes physical or
chemical treatment to extract the valuable metals.
Mineralized material
Mineralized material is the projection of mineralization in rock
based on geological evidence and assumed continuity. It may or
may not be supported by sampling but is supported by geological,
geochemical, geophysical or other data. This material may or may
not have economically recoverable mineralization.
Mining claim
That portion of public or private mineral lands which a party
has staked or marked out in accordance with federal, provincial
or state mining laws to acquire the right to explore for and
exploit the minerals under the surface.
NSR
Net smelter return - a share of the net revenues generated from
the sale of metal produced by a mine.
NERCO Companies
NERCO DeLamar Company, NERCO Metals Inc. and Palms Mining
Company collectively.
Plexus
Plexus Resources Corporation, a predecessor company to Kinross
Gold Corporation.
Preferred Shares
Redeemable retractable preferred shares of the Company as
described fully in the notes to the Consolidated Financial
Statements.
Ore
Rock, generally containing metallic and non-metallic minerals
that can be mined and processed at a profit.
Reclamation
The process by which lands disturbed as a result of mining
activity are reclaimed back to a beneficial land use.
Reclamation activity includes the removal of buildings,
equipment, machinery and other physical remnants of mining,
closure of tailings impoundments, leach pads and other mine
features, and contouring, covering and revegetation of waste
rock piles and other disturbed areas.
Recovery
A term used in process metallurgy to indicate the proportion of
valuable material obtained in the processing of an ore. It is
generally stated as a percentage of valuable metal in the ore
that is recovered compared to the total valuable metal present
in the ore.
Refining
The final stage of metal production in which impurities are
removed from the molten metal.

Reserves
Mineral Resource: A mineral resource is a concentration
or occurrence of natural, solid, inorganic or fossilized organic
material in or on the Earth’s crust in such form or quantity and
of such grade or quality that it has reasonable prospects for
economic extraction. The location, quantity, grade, geological
characteristics and continuity of a mineral resource are known,
estimated or interpreted from specific geological evidence and
knowledge. Mineral resources are sub-divided, in order of
increasing geological confidence, into inferred, indicated and
measured categories: An inferred mineral resource is that part
of a mineral resource for which quantity and grade or quality
can be estimated on the basis of geological evidence and limited
sampling and reasonable assumed, but not verified, geological
and grade continuity. The estimate is based on limited
information and sampling gathered through appropriate techniques
from locations such as outcrops, trenches, pits, workings and
drill holes.
Indicated Mineral Resource: An indicated
mineral resource is that part of a mineral resource for which
quantity, grade or quality, densities, shape and physical
characteristics can be estimated with a level of confidence
sufficient to allow the appropriate application of technical and
economic parameters, to support mine planning and evaluation of
the economic viability of the deposit. The estimate is based on
detailed and reliable exploration and testing information
gathered through appropriate techniques from locations such as
outcrops, trenches, pits, workings and drill holes that are
spaced closely enough for geological and grade continuity to be
reasonably assumed.
Measured Mineral Resource: A measured
mineral resource is that part of a mineral resource for which
quantity, grade or quality, densities, shape and physical
characteristics are so well established that they can be
estimated with confidence sufficient to allow the appropriate
application of technical and economic parameters, to support
production planning and evaluation of the economic viability of
the deposit. The estimate is based on detailed and reliable
exploration, sampling and testing information gathered through
appropriate techniques from locations such as outcrops,
trenches, pits, workings and drill holes that are spaced closely
enough to confirm both geological and grade continuity.
Mineral Reserve: A mineral reserve is the economically mineable
part of a measured or indicated mineral resource demonstrated by
at least a preliminary feasibility study. This study must
include adequate information on mining, processing,
metallurgical, economic and other relevant factors that
demonstrate, at the time of reporting, that economic extraction
can be justified. A mineral reserve includes diluting materials
and allowances for losses that may occur when the material is
mined.
Probable Mineral Reserve: A probable
mineral reserve is the economically mineable part of an
indicated, and in some circumstances, a measured mineral
resource demonstrated by at least a preliminary feasibility
study. This study must include adequate information on mining,
processing, metallurgical, economic and other relevant factors
that demonstrate, at the time of reporting, that economic
extraction can be justified.
Proven Mineral Reserve: A proven mineral
reserve is the economically mineable part of a measured mineral
resource demonstrated by at least a preliminary feasibility
study. This study must include adequate information on mining,
processing, metallurgical, economic and other relevant factors
that demonstrate, at the time of reporting, that economic
extraction can be justified.
The above definitions of “mineral reserve”,
“proven mineral reserve”, “probable mineral reserve”, “mineral
resource”, “measured mineral resource”, and “indicated mineral
resource” conform to Canadian Institute of Mining, Metallurgy
and Petroleum (“CIM”) definitions as defined in the CIM
Standards on Mineral Resources and Reserves - Definitions and
Guidelines as required by National Instrument 43-101 of the
Canadian Securities Administrators, Standards of Disclosure for
Mineral Projects.
Sedimentary rock
Rocks formed from material derived generally by erosion of other
rocks and laid down by a chemical or mechanical process i.e.,
limestone, shale and sandstone.
Stockpile
Broken ore heaped on surface or prepared areas underground,
pending treatment or shipment.
Tailings
The material that remains after all metals considered economic
have been removed from ore during milling. |
