Deposit Type

  • Pegmatite
  • Vein / narrow vein


Summary:

Property geology is largely based on GTK's intelligence results, because Keliber conducted only detailed geological, geochemical, mineralogical and geophysical research in limited areas. The area Keliber includes such properties: Länttä, Syväjärvi, Rapasaari, Outovesi, Leviäkangas, Emmes.

At Länttä, the bedrock is covered by basal till, varying in thickness from 1 m to about 7 m with the pegmatite veins hosted by metavolcanic intermediate rocks, metagreywacke schists and plagioclase porphyrite. The spodumene pegmatite consists of two veins parallel to the host bedding and with a maximum thickness of the two veins of about 10 m. The total length of the veins is about 400 m based on drilling results from 2004 and 2005.

At Syväjärvi, bedrock is covered by sandy till with a mean thickness of about 5 m with the pegmatite veins intruding and cross cutting host mica schist and metagreywacke in an anticlinal structure. Metavolcanic rocks include metatuff, lapille metatuff, metaagglomerate and plagioclase porphyrite. The thickest drilled pegmatite intercepts are 20 - 30 m in true thickness. The pegmatite veins at Syväjärvi dip under Lake Syväjärvi and a 71 m tunnel was driven into the deposit from the lake edge to enable bulk sampling.

At Rapasaari, the bedrock is covered by peat and till, varying in vertical thickness from 3 m to almost 20 m with the pegmatite veins intruding mica schist and metagreywackes in a synclinal system. Metavolcanic rocks o ........


Mining Methods

  • Truck & Shovel / Loader
  • Bench & Fill
  • Backfill


Summary:

Conventional Truck and Shovel was selected as the most suitable mining method for the open pit mining areas. This method involves the use of large, off-highway haulage trucks loaded directly by large shovels or excavators.

The main underground mining method is bench and fill mining and is appropriate for this style of deposit with each ore body being accessed from a decline. Mining will advance from bottom upwards in 20 m high mining lifts and back fill will be waste rock from the open pit and development drives.

Pit and Underground Mine Design.
The geotechnical parameters apart from ramp width required for the pit design were obtained from the Pöyry Geotechnical Study. The ramp width has been calculated using 2.5 times the width of the overall haul truck width. The haul truck used for the design was the Caterpillar 777, which has an overall width of 6.4 m. A 16 m ramp width is used for all pits except for Outovesi, which is a small-scale operation, so a narrower ramp can be used. The 16 m ramp allows for drain ditches and safety berms to be constructed. The final benches in the pit designs have been designed using single lane access which allows the retrieval of extra ore at the base of the pits.

Design of the underground mines provides details of the declines (location, gradient etc.) and the raises needed for ventilation and backfill. The stopes have been designed using €100/t NSR block cut-off and a minimum mining width of 5 m.
