Rock Mechanics Assessment Complete
Amur Minerals Corporation ("Amur" or the "Company"), the
nickel-copper sulphide exploration and development company focused
on the far east of Russia, is pleased to announce that the rock
mechanics (geomechanical) study for mining at its Kun-Manie project
("Kun-Manie") is now complete and has been filed and approved by
the necessary Russian authorities. This evaluation is a component
of the Company's Permanent Conditions TEO ("TEO").
The study, compiled by the Mining Institute of the Far Eastern
Russian Academy of Sciences ("MIFERAS"), was based on the regional
tectonic setting and project specific data derived from the testing
of exploration drill core. It confirms that open pit operations can
be successfully implemented at the Maly Kurumkon / Flangovy and
Vodorazdelny deposits, and at the area identified as ISK (the now
continuous orebody from Ikenskoe / Sobolevsky through Kubuk).
Differing final pit slope angles and operational parameters
accounting for the variability of the geomechanical characteristics
unique to the waste and ore rock types of, and within, each deposit
have been identified for use in the determination of the final
ultimate pit designs and reserve reporting. For any remaining
deeper ores, it has also been confirmed that conventional
underground extraction methods can be utilised. The MIFERAS work
substantially updates previously completed geomechanical analysis
undertaken by SRK (UK) Ltd.
Robin Young, CEO of Amur Minerals Corporation, commented:
"The MIFERAS rock mechanic evaluation confirms that Kun-Manie
can be implemented as on open pit operation. Once open pit
operations are completed, and if the ore located below the ultimate
pit limits is substantial, it has also confirmed that late mine
life extraction of deeper ores using conventional mining methods
can be implemented.
"The rock mechanics evaluation is an important component for the
design of all mines. This information and its inputs will form the
basis for simultaneously establishing on-going operational safety
practices and identification of a life of mine ore production
schedule."
Highlights:
-- The Mining Institute of the Far Eastern Russian Academy of
Sciences evaluation of the regional setting and its associated
stress fields has provided information for inclusion in the design
of buildings, tailings storage facilities and consideration in mine
design for open pit and underground production alternatives.
-- Kun-Manie is located within the Amursky Tectonic Plate along
the southeast boundary of the Siberian Asia Craton. Since 1998,
infrequent seismic activity within 200 km of the site has consisted
of a total of five earthquakes. The magnitude of these earthquakes
has ranged from 3.4 to 5.2 on the Richter Scale with epicenter
depths ranging from between 10 km to 15 km. Globally, approximately
2,200 earthquakes having a 5.0 magnitude or higher occur per annum.
A Richter Scale earthquake of a 5.0 magnitude can be felt and some
property damage to structures may occur. Appropriate considerations
will be incorporated in the design of site facilities and mining
activities.
-- MIFERAS selected representative samples from throughout the
areas from which open pit mining is anticipated. Using industry
standard testing approaches, the properties of the host waste rock
and composition of the ore, geological structure related to mass of
the rocks, faulting and fracturing, morphology of the ore bodies,
degree of hydrothermal alteration and tectonic activities were
evaluated.
-- On an ore processing basis, the density and hardness of the
ores to be milled are mutually supportive of the information used
to estimate resources and reserves and the comminution (crushing
and grinding) parameters for the ore processing plant.
-- Faulting and fracturing associated with the tectonic regime,
complexity of the geology and geomorphology of the ore bodies
increase from west to east along the axis of the mining licence.
Open pit simulations along five representative cross sections
indicate the open pit designs should include variable pit slope
angles depending on rock type, orebody morphology, and fracturing
and faulting. This specifically includes the northeast pit walls
which are characterised by the greatest relief (difference in
elevation between the pit bottom and the pit berm).
-- Analyses of geomechanical results have also been examined and
conventional underground mining approaches can be successfully
implemented below and or adjacent to the designed open pits at
later stages in the mine life.
