Candu
Canada, Deuterium, Uranium. Canadian designed and built pressure
tube nuclear reactor which uses natural uranium as fuel and heavy
water (deuterium oxide) as the moderator.
Dose
Term used to quantify the amount of energy absorbed from ionizing
radiation per unit mass.
Enriched uranium
Uranium in which the content of the isotope uranium-235 has been
increased above its natural value of 0.7% by weight. Typical low-enriched
uranium for commercial power reactors is enriched in uranium-235
to the range of 3% to 5%. In highly enriched uranium, the uranium-235
has been increased to 20% or more.
In situ uranium leaching
A process involving pumping a solution down an injection well where
it flows through the deposit, dissolving uranium. The uranium-bearing
solution is pumped to surface where the uranium is recovered from
the solution.
Light-water reactor
A thermal reactor using ordinary water both as a moderator and as
a coolant with enriched uranium as fuel.
Ounce (oz)
All ounces in this report are troy ounces.
Spot market
The buying and selling of uranium products for delivery within one
year.
Spot market price
Price for product sold or purchased in the spot market rather than
under long-term contract.

Ton (short ton)
UO2
Uranium dioxide. Converted from UO3
at Cameco's Port Hope plant, then compressed to pellets and sintered
by fuel fabricators to make fuel for Candu reactors.
UO3
Uranium trioxide. An intermediate product produced at Cameco's Blind
River refinery and used as feed to produce UO2
and UF6 at Cameco's Port Hope
conversion plants.
U3O8
Triuranium octoxide. At Cameco operations, it is in the form of
concentrate, often called yellowcake.
UF6
Uranium hexafluoride. Converted from UO3
at Cameco's Port Hope plant. Following enrichment, UF6
is converted to enriched UO2 suitable
for fabrication into fuel for light-water reactors.

Reserves
Reserves
That part of a mineral deposit which could be economically and legally
extracted or produced at the time of the reserve determination.
Reserves can be either proven or probable. (This relates to operating
mines and properties at the development or pre-development stage,
based on a positive feasibility study. These reserves include material
in place and on stockpiles with allowances for mining recovery,
dilution and leachability.)
Proven Reserves
Reserves for which (a) quantity is computed from dimensions revealed
in outcrops, trenches, workings or drill holes; grade and/or quality
are computed from the results of detailed sampling and (b) the sites
for inspection, sampling and measurement are spaced so closely and
the geological character is so well defined that size, shape, depth
and mineral content of reserves are well established. (They include
the broken material on stockpiles.)
Probable Reserves
Reserves for which quantity and grade and/or quality are computed
from information similar to that used for proven reserves, but the
sites for inspection, sampling, and measurement are farther apart
or are otherwise less adequately spaced. The degree of assurance,
although lower than that for proven reserves, is high enough to
assume continuity between points of observation.
Resources
Resources
Resources are the estimated quantity, grade and/or quality of mineralization
that is of potential economic merit. A resource estimate does not
require specific mining, metallurgical, environmental, price and
cost data, but the nature and continuity of mineralization must
be understood. Resources can be either indicated or inferred. They
are a potential from which reserves could be defined.
Indicated Resources
Indicated resources are the estimated quantity, grade and/or quality
of part of a mineralized body for which the continuity of grade
and/or quality, together with the extent and shape, are so well
established that a reliable grade and tonnage estimate can be made
for a deposit of potential economic merit. Fundamental to the indicated
resource class is a well-established indication of the geological
continuity of the zones of mineralization.
Inferred Resources
Inferred resources are estimated quantity, grade and/or quality
of a mineralized body, or a part thereof, that is determined on
the basis of limited sampling, but where there is sufficient geological
information and a reasonable understanding of the continuity and
distribution of mineralization to outline a deposit of potential
economic merit.
