GRAPHITE ONE ANNOUNCES FULLY INTEGRATED AMERICAN
GRAPHITE PROJECT INAUGURAL PEA AT US$1.037B NPV, AND 27% IRR
January 25, 2017 – Vancouver, British Columbia – Graphite One Resources Inc. (GPH: TSX‐V; OTCQX:
GPHOF) (“Graphite One”, “GPH” or the “Company”) is pleased to a nnounce the results of its Preliminary
Economic Assessment ("PEA") for the development of its 100%‐owned Graphite One manufacturing
p r oj e c t (t h e “Pr oj e c t ”) . Th e Pr oj e c t i s c on c e i ved as a ve r t i c ally integrated manufacturer of high grade
Coated Spherical Graphite (“CSG”) with mining and processing facilities near Nome, Alaska and advanced
material processing done at a dedicated graphite product manufacturing facility. Washington State is a
potential site for the product manufacturing facility due to it s established maritime links with Alaska, the
availability of low‐cost power, developed industrial sites and proximity to markets. The PEA was prepared
by the independent engineering firm, TRU Group Inc. of Toronto, Ontario, under Canadian Securities
Administrators' National Instrument 43‐101 – Standards of Disclosure for Mineral Projects ("NI 43‐101").
The PEA projects a Net Present Value (“NPV”) for the Project of US$1.037 billion using a 10% discount
rate, with an Internal Rate of Return (“IRR”) of 27%. Annual production of CSG and other graphite
specialty materials is projected at 55,350 metric tonnes when full production is reached in Year 6. A
minimum of 40 years of indicated and inferred resources grading 7% Cg (graphite) have been identified in
the target exploitation zone to sustain full scale operations, notwithstanding additional potential
resources immediately outside the target zone or the broader Graphite Creek property.

PROJECT PROFITABILITY
NPV of US$1.037 Billion; IRR of 27% At Average Selling Price of US$5,054 Per Tonne
Pending a detailed graphite market study, the PEA has opted for a conservative selling price of US$6,200
per tonne for CSG and an average selling price of US$1,500 per tonne for Purified Graphite Powders. The
Project’s average blended price of its manufactured products is US$5,054 per tonne, ex plant, on a 2016
constant US dollar basis. The PEA projects the NPV at US$1.037 billion (pre‐tax) using a 10% discount rate,
with a Project life of 40 years. The IRR is 27%, with payback in Year 4 from the start‐up of production.
This is expected to generate cash earnings of US$182 million pe r year on sales of US$280 million at full
capacity with a consolidated operating margin (“EBDIT”) of 63% o n s a l e s . C S G w i l l d o m i n a t e o u t p u t ,
accounting for 75% of sales volume and 93% of sales revenue, or US$260 million, of the total. Purified
graphite powders will account for the balance with sales of US$20 million.
In its overview of the graphite industry, Canaccord Genuity (Australia) Ltd. stated that the price of coated
spherical graphite was “between US$7,000/t ‐ US$10,000/t” 1. Figure 1 shows the impact of CSG prices
on Project NPV with the corresponding IRR. At the PEA’s CSG as sumed price of US$6,200 per tonne, the
Project’s NPV is US$1.037 billion and the IRR 27%. Also shown is the increase in Project NPV and IRR at
CSG prices in the range of US$7,000 to US$10,000pt based on Canaccord’s research.

Figure 1: Sensitivity of Project’s NPV to CSG Price
The PEA’s sensitivity analysis, summarized in Table 1, examined the effect on the NPV (10% discount rate)
and IRR by running 10% incremental changes in various parameters i n t h e b a s e c a s e f i n a n c i a l m o d e l .
Changing the product selling price had the greatest impact as a 10% change adjusted the NPV by about
US$210 million and the IRR by about 2.9%.
Table 1: Impact of 10% Variation in Selected Parameters on Proj ect NPV and IRR
Variable Parameter (10%) NPV Impact (US$) IRR Impact
CSG Selling Price $210 million 2.93%
Operating Cost $80 million 1.3%
Capital Cost $35 million 1.3%
Graphite (Cg) Recovery $60 million 1.2%
Graphite (Cg) Head Grade $50 million 1.2%
As the Project progresses and technical uncertainties are resol ved or identified risks are mitigated, the
Project NPV could be based on a lower discount rate. Based on the current analysis, the Company has
calculated that the Project NPV at an 8% discount rate would be US$1.4 billion.

TRU concluded: “The robust finan cials for vertically‐integrated production of CSG at the projected unit
pricing of US$6,200 per tonne merits that the Project proceed to a feasibility study to maintain an
accelerated project schedule that would coincide with projected market demand in 2021.”
The report titled “Graphite One Resources Inc., NI 43‐101 Preliminary Economic Analysis On the Graphite
One Project” will be filed on SEDAR and can be viewed at www.sedar.com under the GPH profile or on

“This PEA shows the strong potential of our project as America’s emerging producer of lithium ion battery‐
grade Coated Spherical Graphite,” said Anthony Huston, CEO of G raphite One. “With the prospect of a
low‐cost, 40‐year mine life using half of the identified graphite mineral resources, and given our projected
production costs and conservative pricing assumptions, we are confident that Graphite One has the
potential to become a reliable provider of graphite materials critical to clean‐tech, high‐tech and national
security applications."
The Graphite Creek deposit has a unique morphology that TRU Gro up has named STAX, the acronym for
graphite that is Spheroidal, Thin, Aggregate and eXpanded. The importance of STAX was identified during
exploratory product development test work which achieved high c onversion yield to spherical graphite
which demonstrated high performance during electrochemical testing. According to TRU: “STAX graphite
(subject to study in further extraordinary product development R&D) is projected as being uniquely
amenable for use in several applications, including lithium‐ion and alkaline batteries, greases and
lubricants, friction, motor brushes, crucibles, etc.”
T h e P E A , p r e p a r e d b y t h e T R U G r o u p , s t a t e s t h a t i n r e g a r d t o G raphite One’s spherical graphite:
“Potentially, a significant proportion could be sold domestically, but strategically, Japan and Korea would
be considered accessible markets given the advantageous locatio n of the Graphite One Product
Manufacturing Plant. …Graphite One could potentially become the dominant, if not the only, American
producer, of high grade CSG that is integrated with a domestic graphite resource.”
“It’s been a long road to the PEA,” Huston continued. “As we move into the next phase of development,
w e w i l l c o n t i n u e t o w o r k c l o s e l y w i t h A l a s k a s t a t e a u t h o r i t i e s and the local communities around the
deposit, including the Alaska native corporations, to ensure th a t o u r P r o j e c t m e e t s t h e h i g h e s t
environmental, safety and sustainability standards."
METALLURGICAL TESTING
The PEA summarizes the mineral processing and metallurgical test work programs commissioned to date
by the Company. TRU Group Inc has managed the test work conducted at an independent graphite
laboratory for the characterization of the graphite in the graphite mineralization from the Graphite Creek
deposit and the development of exploratory spherical graphite p roducts. TRU Group has also directed
the development of the mineral processing flowsheet at an indep endent mineral processing laboratory
for the target exploitation zones at Graphite Creek. Below is a summary of the key test work findings.
Naturally occurring Spherical, Thin high‐aspect ratio, Aggregate and e Xpanded structure graphite
morphologies were identified by an independent graphite laborat ory in graphite mineral drill core
samples taken from the Graphite C reek Property. STAX structures were concluded to be inherent

attributes to Graphite Creek not found in any other graphite project under development or in commercial
operation. Exploratory product de velopment test work at an inde pendent graphite laboratory on select
graphite mineral samples from Graphite Creek demonstrated the direct conversion of purified STAX
graphite into spherical graphite at much higher yield of 74.6% compared to the normal industry yields of
30‐40% when processing conventional flake graphite. Also, in contrast to industry norms, the STAX‐
derived spherical graphite was produced from a broad particle size distribution in the feed, which required
no prior size reduction and was converted to spherical graphite in the spheronizing mill with 1/3 of the
energy input typically used with conventional flake graphite. T hese features of STAX graphite potentially
offer Graphite One distinct technical advantages to mass produce high quality spherical graphite at lower
cost.
Coin cells (batteries) containing STAX‐derived exploratory spherical graphite and coated spherical graphite
anodes were manufactured and tested at the independent graphite laboratory. The reversible discharge
capacities recorded in these coin cells were at or near the the oretical values for na tural graphite of 372
Ah/kg; in repeat charge‐discharge cycles. STAX‐derived spherical graphite attained a reversible discharge
capacity at 372 Ah/kg while STAX‐derived coated spherical graphite reached a reversible capacity of 370.1
Ah/kg. In a unique test, STAX‐derived spherical graphite also d emonstrated good performance stability
over short duration (50 hour) continuous recharge‐discharge cycling.
Mineral beneficiation tests on Graphite Creek drill core samples that were representative of the targeted
exploitation zone were conducted at a bench scale at an indepen dent mineral processing laboratory to
validate process assumptions and performance of the TRU rendere d flowsheet that is the basis of the
proposed Graphite Creek Mineral Processing Plant. In the proposed flowsheet, crushed graphite mineral,
grading 7% Cg, is milled to a pulp and conditioned with reagent s. The pulp then passes to preliminary
flotation recovery of graphite in a rougher stage followed by a cleaner stage. Both flotation stages are
conducted in conventional impeller mixed flotation cells. Subsequent upgrading of the recovered graphite
is performed in four cleaning stages using flotation columns. Each cleaning column flotation stage is
preceded by a polishing grind (milling) of the feed which effec ts greater liberation of the graphite from
other minerals (gangue). In tests that reproduced prior works and the TRU rendered flowsheet, test results
project that a single graphite concentrate will be produced at a grade of 95 % Cg (graphitic carbon) at an
overall graphite recovery of 80%.

*Mineral resources are not mineral reserves and do not have demonstrated economic viability.
There is no guarantee that all or any part of the indicated or inferred mineral resource will be
converted into a mineral reserve. The collective work to date from the Graphite Creek Property
indicate that while the project is in early stages of exploration/resource work that indications of the
size and grade of the graphite give suggestions that they are of high enough concentration to be of
economic interest.
Based on the mineral resources identified to date and reviewed in the PEA, the Graphite Creek deposit
contains an estimated 10.3 million tonnes classified as Indicated Resources and 71.2 million tonnes
classified as Inferred Resources, both at a 6% graphitic carbon (Cg) mining cut‐off grade. See Table 2.

Resource estimates are based on the cumulative drill data from the Company’s 2012, 2013, and 2014 drill
programs totaling 48 holes and about 7,500 metres of drilling. The yellow rectangle in Figure 4 outlines
the Inferred Resource area and the green rectangle, the Indicated Resource area.

The Project’s economic analysis has been designed based on the 6% mining cut‐off grade, producing the
desired 7.0% Cg mill‐feed head gr ade. The scale of available m aterial at 7% Cg is estimated to be 43.66
million tonnes using both Indicated and Inferred Resources, sufficient to support over 40 years of mining
at full‐scale production of 1,018,000 tonnes per year.
Follow‐up exploration and development is recommended based on r esults from: 1) historic and recent
(2011‐2014) exploration and laboratory work; 2) the lateral con t i n u i t y o f a t l e a s t n i n e m i n e r a l i z e d

Mountains to reduce the strip ratio and maximize access to the high‐grade graphitic schist. The cost to
complete the next exploration program is estimated to be US$5.4 million plus a 10% contingency.
Graphite Creek Mine
The Graphite Creek deposit outcrops at the surface, along a significant length of outcrop and maintains a
relatively shallow dip below the land surface. The area select ed for modelling, and planned for mining is
located along a relatively continuous 1500‐metre outcrop and appears to be segregated into three
separate zones of graphite mineralization. Surface mining is proposed using a truck and shovel operation
