Belt
is a
narrow
linear stretch of land having
series of deposits
of
associated minerals, such as, Colorado gold-molybdenum belt, US, Grant
uranium mineral Belt, New
Mexico Khetri
copper
belt, Rajpura-Dariba-Bethumni
zinc-lead-silver belt, Rajasthan,
Sukinda
chromite belt, Orissa,
India.
Deposit
is
comprised of a single or a group of mineral occurrences
of sufficient size and grade separated
by natural narrow barren parting.
Examples Broken
Hill group of zinc-lead
deposits, Australia, Zawar
group of zinc-lead deposits, India, Red
Dog zinc-lead deposit, Alaska, OK Tedi
copper deposit, Papua
New Guinea, Olympic
Dam copper-gold-uranium-silver deposit, South

Block
is a
well-defined
area having
mineral concentration wholly
or partly of economic value, such as Broken Hill main, Australia, Bailadila
deposit-14,
Central Mochia, India. The
blocks in underground
mining are
subdivided to “Level”
(say: upper level, lower level, 500-700 and 300-500
mRL).
The levels are further split into “Stope” (say:West 301 stope,
North 101 stope,
Valley stope).
These terms
are locally convenient to use for attention and allocation
of work activities in mineral exploration and sequencing
mine production block.
