why

Engineering consultant, Lower Quartile
Solutions Pty Ltd (LQS) was engaged to
run provisional open pit optimisations
using Whittle software on the Indicated
portion of the Maitland Mineral Resource.
The optimisations were run using a range
of copper prices ranging from A$3,500 per
tonne to A$10,000 per tonne. Cost
parameters were provided by Glengarry
and analysed by LQS to ensure they were
robust estimates.
The optimisation results indicate positive
cash flows are possible from copper prices
as low as A4000 per tonne. The
Scoping Study assumes that ore will be
transported to a mill up to 350 kilometres
away and that limited infrastructure would
be required on site.


I would love to see the complete report but i suppose that is not available to the public.
