Sunridge Gold Announces $837 Million Net Present Value Feasibility Study for the Asmara Project, Eritrea

  Sunridge Gold Announces $837 Million Net Present Value Feasibility Study for
  the Asmara Project, Eritrea

Business Wire

VANCOUVER, British Columbia -- May 16, 2013

Sunridge Gold Corp. (SGC:TSX.V/SGCNF:OTCQX) is pleased to announce the
completion and positive results of an independent feasibility study (the
“Study”) by lead engineer SENET (Pty) Ltd. ("SENET") for its Asmara Project in
Eritrea. The Study demonstrates that the mining of all four advanced deposits
that make up the Asmara Project (Emba Derho, Adi Nefas, Gupo Gold and Debarwa)
and processing of the ore near the large Emba Derho deposit is economically
robust with a Net Present Value (“NPV”) of $837 million. The Study outlines a
three-phase staged start-up mining plan which would initiate production almost
one year earlier than was envisaged in the prefeasibility study. This earlier
cash-flow, combined with capital cost reductions, reduces the initial capital
requirements to be financed by over $130 million.

As a result of the positive outcome of the Study, Sunridge will continue work
towards bringing the Asmara project into production as soon as possible, by
completing required environmental studies, applying for the mining license,
arranging debt financing, commencing detailed engineering work and hiring new
key employees. Management estimates that initial production on the Asmara
Project will commence in mid-2015.

Base Case Highlights (all $ equals US dollars):

  *NPV of $837 million at a 10% discount (pre-tax)
    NPV of $443 million at a 10% discount (post-tax)

       *436,000 ounces of gold
       *11 million ounces of silver

  *Life of Mine – 1 construction year, 15.3 production years

Michael Hopley, President and CEO of Sunridge Gold states, “We are delighted
with the results of the Asmara Project feasibility study which demonstrates
even stronger economics and a superior mining plan than the prefeasibility
study that was completed a year ago. We have been able to successfully reduce
initial capital costs by instituting a 3 phased start-up plan that starts
production a year earlier than previously planned. In a little over two years,
the Asmara Mine can start production and become a very important producer of
copper, zinc, gold and silver for the benefit of Sunridge shareholders and the
Eritrean people.”

Mining and Production

The Study has concluded that the processing of gold and silver ores from Emba
Derho, Gupo Gold and Debarwa by heap-leaching as well as the processing of
copper and zinc ores from Emba Derho, Adi Nefas and Debarwa by milling and
flotation at facilities near Emba Derho provides the optimum economic
scenario. The Emba Derho, Debarwa and Gupo deposits will be mined by open-pit
methods and the Adi Nefas deposit by underground mining methods.

The mining plan consists of a 3 phase start up in order to reduce initial
capital costs. In Phase I, the high-grade copper (Phase IA) (direct shipping
ore “DSO”) will be mined, crushed to less than 10 mm, loaded into containers
and transported 120 km to the port facility at Massawa for shipping to a
smelter.

In addition, (Phase IB) near surface gold and silver ore will be mined from
the Debarwa, Emba Derho and Gupo deposits and trucked to the same crushing
facility near Emba Derho and processed in the gold recovery heap-leach
facility. The heap-leach facility is located inside the tailings storage
facility and available until Year 5 of operations.

During Phase II, supergene copper ores will be mined from both Debarwa and
Emba Derho and processed at a central flotation plant at Emba Derho at a
nominal rate of 2 million tonnes per annum. Copper concentrate with gold and
silver byproduct will be transported to the Port of Massawa and shipped to
smelters.

Full Production will be achieved in Phase III. Primary copper and zinc ores
from Debarwa, Adi Nefas and Emba Derho deposits will be processed at a
flotation plant at Emba Derho at a nominal rate of 4 million tonnes per annum.
Copper concentrate with gold and silver byproduct and zinc concentrate will be
transported to the port facility at Massawa for shipping to smelters.

Power will be generated onsite using a combination of diesel and medium fuel
oil generators. Water supply is sourced from the capture of rainfall in ponds
and recycled within the plant.

Phase I - DSO and Gold Production (Year 1 – Year 5)

Phase IA – DSO (Year 1 – Year 2)

    silver
  *Final Waste/Ore ratios – 2.5:1 at Emba Derho, 9.8:1 at Debarwa and 1.7:1
    at Gupo
  *Adi Nefas to be mined using underground long hole bench retreat ranging
    between 150,000 and 470,000 tonnes per year for a total of 1.682 million
    tonnes mined over 6 years and blended with ore from Emba Derho
  *Phase III recoveries average 86% copper, 86% zinc, 48% gold, 44% silver

When the mining license is granted the Government of Eritrea will have a 10%
carried interest in the project and ENAMCO (Eritrean National Mining
Corporation) will be purchasing an additional 30%. ENAMCO will therefore be
responsible for 33.33% of all capital and operating costs of the mine.

The mineral reserves listed in Table 5 were created for Emba Derho, Debarwa
and Gupo by generating Net Smelter Return (NSR) values (revenue minus royalty
and smelting/selling costs) for each metal using Measured and Indicated
Resources only. The net revenue of each block was compared to total cost. Each
mining block becomes economical and is included in the processing schedule if
it is above the total combined cost of processing, general administrative and
applicable transport.

In the case of the Adi Nefas underground mine the mineral reserves were
generated through a sequential process of NSR calculation, stope optimization,
stope design, and development design. Stope optimization was applied using
Snowden’s Stopesizor software which modifies the resource to reflect minimum
mining width for the NSR. The outcome is a set of blocks that reflect this
recoverable resource. Unplanned dilution was added to the model through adding
a fixed width of over break waste into the planned stopes.

The mineral reserve listed in Tables 5 was generated from the Measured and
Indicated resource after the application of the economic cut-off grades for
each rock type, open-pit design, external dilution and recovery parameters.

Social and Environmental Studies

Social and environmental baseline studies and stakeholder engagement programs
are well advanced on all four deposits that are included in the Study. This
work has been completed to comply with the Equator Principles and the
International Finance Corporation Performance Standards for Social and
Environmental Impact Assessment Studies, as well as the Eritrean Government
“National Environmental Assessment Procedures & Guidelines”. The work is being
carried out by the Sunridge social and environmental staff and consultants
(both international and national) and will lead to the publications of a
Social and Environmental Impact Assessment (SEIA). It is expected that the
SEIA will be completed and submitted to the government in September 2013.

Project Location and Access

All four deposits included in the Study are located within a 30 minute drive
on paved roads from the capital city of Asmara with close proximity to power,
water and an international airport. In addition, the Red Sea port city of
Massawa is approximately 120 kms east of Asmara via paved road.

Project Opportunities

Opportunities to further enhance the economic value of the Asmara project will
be investigated during an early phase of detailed engineering as part of
Engineering, Procurement and Construction, Management (EPCM).

Sunridge will investigate opportunities to optimize process rates with
existing equipment and increase value in the process schedule while reducing
operating and cash flow risks.

Sunridge will continue to explore and evaluate other deposits and targets in
the vicinity.
