Inmet Mining provides update on Las Cruces Project



    TORONTO, June 9 /CNW/ - Inmet Mining Corporation (IMN-TSX) today
announced an update with respect to the mid-May suspension of the
authorization for the Las Cruces dewatering and re-injection system (DRS) by
the Confederacisn Hidrografica del Guadalquivir (CHG).

    Background of the DRS System

    The DRS is a system of 69 water wells located in the proximity of the Las
Cruces open pit that extracts water from the surrounding aquifer and
re-injects it into the same aquifer through adjacent wells to prevent water
from flowing into the pit.
    The DRS was designed as part of the open pit mining concept and was
permitted by CHG in October 2003 after a two-year review. The purpose of the
DRS is to ensure that the regional aquifer is not affected by the operation of
the mine. The aquifer is a formation of sand that lies approximately
150 metres below the surface and allows groundwater to accumulate. Under the
conditions of the DRS authorization, Las Cruces is permitted to extract a
small amount of water from the aquifer. The majority of process water required
by Las Cruces will be recycled from the Seville sewage treatment facility.

    CHG Suspension Resolution and Inmet's Response

    Since the suspension of the DRS authorization, Las Cruces has stopped all
mining in the area of the ore deposit. However, some mining of overburden
material for future pit expansions has continued. Construction of the process
plant has not been affected by the suspension of the DRS authorization. Las
Cruces has also continued to operate elements of the DRS to ensure the
environmental protection of the aquifer and the integrity of the open pit.
Water that is accumulating in the bottom of the pit is being pumped into lined
storage ponds as an interim measure.
    To address CHG's concerns that led to the suspension of the DRS
authorization, Las Cruces has developed a plan that contains two proposed
primary actions. The first proposed action involves purification of water
extracted from the aquifer through a highly efficient reverse osmosis water
treatment process prior to reinjection into the aquifer. Such purification
would provide a safeguard should water become impacted in the future. To
accelerate the implementation of water purification, Las Cruces has sourced
two reverse osmosis treatment units from a US supplier that can purify up to
half of the quantity of water extracted from the aquifer. Las Cruces'
objective is to be in a position to commence water purification on an interim
basis by the end of August. The second proposed action is the relocation of
certain DRS extraction wells currently located above the mineralized zone to
locations outside of the mineralized zone. We expect the cost of implementing
both actions to be approximately US$15 million.
    Las Cruces has already outlined its proposed actions in a letter to CHG
and will submit the technical aspects of its plan to CHG by June 13, 2008.
Although Las Cruces has and will continue to dedicate all its efforts towards
satisfying CHG's concerns, it is possible that the suspension period may
continue past Las Cruces' expected start of cathode production, which we have
anticipated would be in the fourth quarter of this year. In that case,
start-up of operations at the Las Cruces process plant and resumption of
mining activity in the pit, including the mining of ore for the process plant,
would be delayed until the DRS authorization is reinstated.
