Dioro Exploration NL - HBJ pit geotechnical event


    PERTH, Western Australia, Feb. 2 /CNW/ - DIORO EXPLORATION NL ABN 31 009
271 532 (ASX/TSX: DIO) - Dioro advises that a substantial wall failure has
occurred in the west wall of the HBJ pit as foreshadowed in the news release
made on 23 December 2008.
    On the 28th January the South Kal mine site received approximately 70mm
of rain from Cyclone Dominic that caused extensive flooding in the Kalgoorlie
district. Although remediation work undertaken during December 2008 and
January 2009 is likely to have assisted in slowing the wall movement and
allowed for mining during January, this heavy rain further hastened the wall
movement described in the December release and has resulted in a major slip on
31st January.
    Consequently the company has immediately ceased all mining at the HBJ
pit. All staff and equipment was removed from the pit well prior to the
    The company is assessing the extent of the wall failure to determine its
impact on the mining of HBJ, however the company has decided to postpone
further mining in the HBJ pit until a full feasibility study is completed.
    During December following the increase in the HBJ wall movement, the
company commenced preparation works for the mining of Mt Martin and Mt Marion,
consistent with the existing business plan.
    Whilst the feasibility study and preparation works referred to above are
being conducted, the Jubilee mill will continue processing newly mined ore
from the Frog's Leg mine and previously mined and stockpiled ore respectively.
At the end of December the company had in excess of 220,000 tonnes of medium
grade stockpile adjacent to the Jubilee Mill and in excess of 1,000,000 tonnes
of low grade stocks at 0.8g/t.
    December was a record month for the Frog's Leg underground mine with
approximately 45,000 tonnes mined @ 4.86g/t (100%). Dioro's 49% share of ore
from the Frog's leg mine is processed at the Jubilee mill. The mining and
processing activities from this operation are currently cash flow positive for
