re: Ann: Penumbra Mine Equipment Delivered fo... Key points:
? Penumbra Mine decline development almost two thirds complete and advanced to a total
combined length of 474m as at 10 August 2012
? Completion of the twin declines and first coal production forecast for 30 October 2012 with
ramp up to full 750,000 tpa ROM production by 30 June 2013

Key points:
? First Continuous Miner and associated Shuttle Cars delivered to the Penumbra Mine site and
being prepared prior to the commencement of mining next month
? Penumbra Mine decline development advanced to a total combined length of 593m as at 20
September 2012

so in that 5 week period they progressed 119m.

"The remaining 155m of decline is forecast to be completed over the next 5 weeks to allow
underground mining activities to commence by 30 October 2012." from todays ann. so they are ramping up work on the declines to meet deadlines??????

but it doesnt add up with there graphs.

10 aug.
conv. decline 31.1m from 169m 18.4% complete.
trav. raod 32.5m from 169m 19.2% complete.

20 sept.
conv. decline 57m from 169m 33.7% complete.
trav. raod 75.3m from 169m 44.6% complete.

the maths dont add up to me or am i missing something???
