VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 3, 2017) - Serengeti Resources Inc. (TSX
VENTURE:SIR)(FRANKFURT:34S) announces the completion of an independent NI 43-101 compliant Preliminary Economic
Assessment ("PEA") for its 95% owned Kwanika copper-gold porphyry project located in the Quesnel Trough of North-Central British
Columbia, Canada. The results of the PEA demonstrate the potential technical and economic viability of establishing a new
copper-gold mine and mill complex on the property.
PEA Highlights:
- Pre-tax NPV 7% of CDN $324 million, 21.1% IRR, 15 year mine
life.
- Life of mine (LOM) metal production of 601 million pounds copper, 676,300 ounces gold, and 2.66 million ounces
silver in concentrates.
- Annual metal production of 50.4 million pounds of copper, 70,100 ounces of gold, and 181,100 ounces of silver in
concentrates for the first eight years.
- Initial capital cost of CDN $476 million plus LOM sustaining capital of $37 million for a 15,000 tpd (5.4 million
tpa) mill and combined open pit, underground mining operation.
- Projected C1 (Direct cash cost of production per pound of copper net of gold, silver credits) of
US$0.70/lb/Cu for first eight years or US$1.20/lb LOM
"We are very pleased to have achieved this important milestone for the Kwanika project," commented David W. Moore, Serengeti
President & CEO. "Kwanika represents an opportunity to develop a midsize green field copper-gold project in an excellent location
and proven jurisdiction. Furthermore there remains excellent potential to expand and upgrade the resources considered in this
study, both in the Central and South Zones. The results of this PEA have confirmed what the partnership believed was the
possibility for higher grade production from the Central Zone at Kwanika and the resultant positive impact on project economics.
Given the economic value we have demonstrated in this PEA, we expect our partners Daewoo Minerals Canada will elect to
fund the next $7 million expenditure to earn an additional 30% interest in the project and we look forward to working with them
in advancing the Kwanika project towards production," stated Moore.

* Pit constrained mineral resources are reported in relation to a conceptual Whittle pit shell and underground
resources are reported within the area for potential underground development. Mineral resources are not mineral reserves
and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate.
All composites have been capped where appropriate. |
** Pit constrained mineral resources are reported at a copper equivalent cut-off of 0.13% and underground resources
are reported at 0.27%. The cut-offs are based on prices of US$3.00 per pound of copper, US$1,300 per ounce of gold, US$20
per ounce of silver, US$9.00 per lb of molybdenum and assumed recoveries of 89% for copper, 70% for gold, 75% for silver,
and 60% for molybdenum. |
The MMTS mining study has focused on a higher grade core of the deposit and delineated combined open pit and underground
designs on the Central and South zones as follows:

All mineralized material classified as Indicated (67%) and Inferred (33%) Mineral Resources has been considered in the
mine plan. The PEA is preliminary in nature and it includes inferred mineral resources that are considered too speculative
geologically to have the economic consideration applied to them that would enable them to be characterized as mineral reserves.
Mineral resources that are not mineral reserves, do not have demonstrated economic viability and there is no certainty that the
results of the PEA will be realized.

Project Development Plan
The proposed project is to develop a green-fields copper-gold-silver deposit with a combination of open pit and block cave
underground mining for the Central Zone and open pit mining for the South Zone combined with conventional milling and flotation
concentration methods. The production rate assumed is 15,000 tonnes per day with a forecast mine life of 15 years. Mineral
concentrate would be trucked approximately 190 kilometers to a rail load-out facility in Fort St. James, rail to Prince Rupert,
and ocean transport to Asian smelters. Forestry Service Roads and the existing Kemess mine power line which is connected to the
power grid, are in the local area which reduces the offsite infrastructure costs. A traditional tailings storage facility
(TSF) will be augmented by using all open pit waste to buttress the dam to increase the factor of safety and a separate water
storage dam and water treatment plant are included, so that surplus water can be discharged safely to the environment and not
stored in the TSF.

Assumed capital and operating costs for the operation are as follows (in CDN$):
- Initial capital of $476.2 million including open pit pre-stripping mining costs, the start of underground access
development, and construction of the processing plant, site infrastructure, construction of a tailings storage facility, access
and power with a contingency of $61.0 million
- LOM sustaining capital cost of $ 36.6 million is predominately for underground equipment when the Block Cave production
starts early in the operating schedule. Ongoing underground development is included in operating costs. An additional $46.3
million is also included in operating costs for final reclamation and closure. Future studies will develop a more cost
effective allocation of the costs of these activities, when more project details from the environmental studies, permitting
obligations, and progressive reclamation details are known.
Open pit operation and equipment will be contractor supplied and well as underground development. Underground operations will
be an owners' team for mucking and hauling from the extraction level of the Block cave.
- Total weighted operating cost of $21.15/ tonne processed including: open pit mining $2.97 / tonne mined; LOM open pit strip
ratio of 1.69, underground block cave mining $11.73 / tonne mined; mill and tailings $9.00 / tonne; G&A $1.95 /
tonne
Recommendations for Further Work and Opportunities to Enhance Value
The independent consultants have recommended advancing the project to a higher level of study leading to a Pre-Feasibility
Study and eventually to a Feasibility Study. The immediate work will require field work and data gathering for Pre-Feasibility
engineering and baseline environmental studies in preparation for consultation with First Nations, sustainability discussions
with local stakeholders and preparations for permit applications with regulators. This will include additional drilling to
improve the modelled resource classification, geotechnical drilling, starting long duration waste rock characterization studies,
and background environmental field surveys.
Furthermore as demonstrated by K-177 drilled in the course of the 2016 program, potential exists to significantly increase
gold and to a lesser extent, copper grades, within the high grade domain of the Central Zone by drilling additional holes
oriented perpendicular to the deposit's E-W long axis. K-16-179 also opened up the NW corner of Central Zone for expansion and
deepening of this hole is recommended along with additional drill holes in this area. Finally the recent mine modelling as part
of the PEA has demonstrated that several areas of better grade exist below the currently planned South Zone pits which with
additional drilling could be brought into a future mine plan.
Daewoo Deal Terms
This PEA was completed as part of a program funded by Daewoo Minerals Canada, whereby Daewoo earned a 5% project interest by
paying Serengeti $400,000 and spending $800,000 on the project within the first year. Daewoo may earn an additional 30%
interest in the project, by electing within 90 days of completion of the PEA report, to fund an additional $7 million over the
next two year period. Serengeti remains as project operator and is entitled to charge a 10% operator fee on expenditures
beyond the initial $1.2 million. Serengeti is entitled to an NSR royalty if its project interest is diluted below 50% and
also retains the right to enter into precious metal streaming transactions subject to certain off-take rights to Daewoo (see
NR 2016-03, April 6 th , 2016 for full details).

Cautionary Statement
This document contains "forward-looking statements" within the meaning of applicable Canadian securities regulations. All
statements other than statements of historical fact herein, including, without limitation, statements regarding exploration plans
and other future plans and objectives, are forward-looking statements that involve various risks and uncertainties. There
can be no assurance that such statements will prove to be accurate and future events and actual results could differ materially
from those anticipated in such statements. Important factors that could cause actual results to differ materially from our
expectations as well as a comprehensive list of risk factors are disclosed in the Company's documents filed from time to time via
SEDAR with the Canadian regulatory agencies to whose policies we are bound. Forward-looking statements are based on the
estimates and opinions of management on the date the statements are made, and we do not undertake any obligation to update
forward-looking statements should conditions or our estimates change, other than as required by law and readers are further
advised not to place undue reliance on forward-looking statements. The information in this News Release related to the
Kwanika Copper/Gold Project was derived from the PEA. Statements pertaining to projected revenues and cash flows, quantity and
grade of mineralized materials, estimated mineral prices are forward-looking statements. The Company cautions that this PEA
is preliminary in nature, and is based on technical and economic assumptions which will be evaluated in further studies. The
PEA is based on the current (as at January 2017) Kwanika estimated resource model, which consists of material in both the
indicated and inferred classifications. Inferred mineral resources are considered too speculative geologically to have
technical and economic considerations applied to them. The current basis of project information is not sufficient to convert
the mineral resources to mineral reserves, and mineral resources that are not mineral reserves do not have demonstrated economic
viability. Accordingly, there can be no certainty that the results estimated in the PEA will be realized.
