AQUILA RESOURCES ANNOUNCES RESULTS FROM NEW PRELIMINARY ECONOMIC ASSESSMENT FOR BACK FORTY PROJECT
Aquila Resources Inc. has received positive
results from its new preliminary economic assessment on the Back
Forty project in Michigan's Upper Peninsula. The PEA, which incorporates a revised mine plan based on results
from Aquila's 2013 resource update, was completed by Tetra Tech Inc.
after considering various trade-off studies which looked at different
mine configurations to determine the optimal scenario for the project.
The PEA will be filed on SEDAR within 45 days and will also be available on Aquila's website. All
figures quoted are in U.S. dollars unless otherwise specified.
PEA highlights
The PEA contemplates mining 16.1 million tonnes of mineralized material over the
16-year life of mine, of which 12.5 million tonnes is open pit and 3.6 million is
underground. The PEA demonstrates the potential for a diverse earnings
stream with a payable metal value mix of 41.2 per cent gold, 40.5 per cent zinc, 12.0 per cent
copper, 5.7 per cent silver and 0.6 per cent lead.
KEY ECONOMIC HIGHLIGHTS

NPV at 6% $247.2M $184.7M
IRR 34.9% 28.9%
Payback period 1.6 years 2.1 years
The PEA includes inferred resources that are considered too speculative
geologically to have the economic considerations applied to them that
would enable them to be categorized as mineral reserves. There is no
certainty that the PEA results will be realized.
Highlights from the PEA include:
- Operating at an initial throughput rate of 5,350 tonnes per day, the total payable
production of the mine is expected to be 532,000 ounces of gold,
704 million pounds of zinc, 63 million pounds of copper, 4,645,000 ounces of silver and 11 million pounds of lead;
-
A total estimated initial capital cost of $261-million comprising $177-million of direct preproduction capital expenditure, a $44-million contingency, and $40-million of indirect and owner's costs;
- The average on-site operating costs are $29.25 per tonne processed for
open-pit mining and $66.20 per tonne processed for the underground
mine;
- The near-surface characteristics of the orebody provide the opportunity
to develop a low capex, high-grade initial phase operation. The
economics of this are still being evaluated as part of the PEA and will
be reported when complete.
"The results from our PEA validate our decision to acquire 100 per cent of Back
Forty and focus on strategic assets in this promising region," stated
Barry Hildred, chief executive officer of Aquila. "The PEA and new mine
plan show marked improvements across key metrics. Ultimately, we
believe this PEA demonstrates the potential of Back Forty while
carefully considering the interests of all our key stakeholders."
Mark Burridge, chairman of Aquila, stated: "Our focus is now on
recommencing project development at Back Forty. The PEA provides a path
forward for the next set of project milestones, including the ramp-up
of permitting activities, and the commencement of a feasibility study
and an exploration program initially focused on near-mine satellite
targets."
Sensitivity analysis
A sensitivity analysis was performed to test the economic viability of
Back Forty against possible fluctuations in commodity prices.

Mineral resources
In February, 2013, Aquila updated its mineral resource estimate. The 2014
PEA incorporates the results from this updated resource, of which 90 per cent
was classified as measured and indicated, and only 10 per cent inferred. Please
refer to Aquila's annual information form dated March 31, 2014, for
further information regarding the updated mineral resource estimate.

Notes
- Mineral resources are not mineral reserves and do not have demonstrated economic
viability.
- Net-smelter-returns cut-off values for the 2013 resource estimate were based on
metal price assumptions of 96 U.S. cents per pound zinc, $3.65 (U.S.) per pound
copper, $1.01 (U.S.) per pound lead, $1,456.36 (U.S.) per troy ounce gold and
$27.78 (U.S.) per troy ounce silver. Metallurgical recoveries were determined and
applied for each of the metallurgical domains determined for the deposit. Average
cut-off value for the open-pit resource contained within an optimized pit shell
was $27.75 (U.S.). Average cut-off value for the underground resources outside of
the optimized pit shell was $66.45 (U.S.).
Project potential
The optimized mine plan provides some flexibility in the development of
the project including a low capex, high-grade initial phase operation.
This option would focus on mining near-surface, high-grade zones by way
of three small open pits in order to maximize capital return in the
early years of production. This approach has the potential to provide
attractive economic returns, mitigate certain start-up risks and allow
for significant optionality in the long-term development of the
project. This opportunity would be fully evaluated during the
feasibility stage of project development and could be pursued depending
on future macroeconomic conditions.
Other opportunities for consideration include optimization of the
underground mining approach, which was not completed as part of the
PEA, improving processing performance and defining the upside
potential, including further exploration and expansion of the
underground resource, in-pit targets and near-mine drill targets,
which have the potential to extend mine life and improve project
economics.
