Stem 7 Signs Agreement to Acquire 100% Interest

in Santa Cruz Graphite Project;

Concurrent Project Financing Announced

October 23rd, 2017 – Vancouver, B.C. - Stem 7 Capital Inc. (“Stem 7” or the “Company”)

(TSXV: STS.H) is pleased to announce (further to an announcement made on June 29th, 2017)

that it has entered into a binding Definitive Agreement (the “Agreement”) with Brasil Graphite

Corp. to acquire a 100% interest in the advanced-stage Santa Cruz Graphite Project in the Bahia

State of Brazil (“Santa Cruz”). The Santa Cruz project is the subject of a recently completed

NI43-101 Preliminary Economic Assessment (“PEA”) which indicates a 78 percent after tax

Internal Rate of Return (‘IRR”). The Company also announces a private placement of units to

raise up to C$6,000,000 to fund the acquisition and development of Santa Cruz.

The Company believes that the Santa Cruz Graphite Project offers several distinct advantages

over other graphite projects including excellent infrastructure and location, low capex and opex,

and significant resource expansion potential. In addition, the resource has excellent granulometry

with approximately 63% of the graphite concentrate produced in pilot plant testing being the

more valuable jumbo to large flake sizes (+30, +50 and +80 mesh). Mr. Eric Allison, Chief

Executive Officer of the Company stated “the Company is very excited to be advancing its

Brazil focused project development strategy with the completion of these important steps in the

acquisition of the Santa Cruz Graphite Project. We firmly believe that the many positive aspects

of this first project, coupled with the excellent team we have assembled, are the critical initial

building blocks for the Company to achieve its goal of creating long-term shareholder value”.

About the Santa Cruz Graphite Project

Company management was attracted to Santa Cruz due to its advanced-stage status as a pre-

production graphite project, backed up by a positive NI43-101 Preliminary Economic

Assessment that supports the need for further studies to evaluate and advance the project's

potential. The Company has filed a copy of the PEA for Santa Cruz with the TSX Venture

Exchange (the “Exchange”) and will file the PEA on Sedar within 45 days of this news release.

The PEA will outline the following parameters for a Santa Cruz graphite production base case:

The PEA will have an effective date of August 21, 2017, which is the effective date of the

mineral resource estimates contained in this news release. The mineral resources in this news

release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM)

CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the

CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

The PEA also outlines significant geological potential to expand graphite resources at Santa

Cruz. Located in the second-largest graphite producing district in the world, the project consists

of thirteen (13) approved exploration licenses covering approximately 13,000 hectares. The

project benefits from at-surface mineralization containing large and extra-large graphite flakes.

The mineralization currently defined is contained in highly weathered saprolite that is free

digging and requires no drilling or blasting. Significant work has been completed to date

including over 7,000m of drilling and a pilot plant test on over 30 tonnes of mineralized material

which produced high-quality concentrates.

Graphite mineralization at Santa Cruz remains open at depth and along strike with significant

room for expansion. The current 43-101 resource is defined down to only 40 meters. The

Company has extensive exploration drilling planned to extend known areas of graphitic

mineralization and significantly increase the graphite resource potential at Santa Cruz.

Planned future development at Santa Cruz includes:

• Additional 2,000 – 4,000 meters of drilling in main resource areas in order to increase

measured and indicated and expand current known resource

• Complete Environmental Impact Study and Mining License Application

• Additional 1,000 to 3,000 meters of drilling in satellite targets

• Further rotary drilling for exploration potential

• Investigate further use of geophysics

• Geologic mapping and further investigations of satellite targets. Only 5% of the 13,000

hectares has been explored.

• Develop and carry out condemnation drilling once preliminary layouts are finalized

• Optimize the mine plan.

Santa Cruz has excellent infrastructure and logistics. High-tension power is within 3 km of the

plant site along with a major natural gas line within 5 km. City water and wastewater are within

3-5 km and access to the project is provided by a well-maintained 1.3km long road connecting to

a main highway. The major port of Ilheus is 270 km away via paved federal highways.

As consideration for the BGC Shares, the Company will issue 9,444,903 units (the

“Consideration Units”) to certain shareholders and nominees of BGC at a deemed price of

C$0.45 per Consideration Unit and pay US$850,000 to BGC. Each Consideration Unit will be

comprised of one common share of the Company (a “Consideration Share”) and one share

purchase warrant (a “Consideration Warrant”). Each Consideration Warrant will entitle the

holder to acquire one additional common share of the Company at a price of C$0.75 per common

share for a period of two years after closing. The Consideration Warrants will be subject to

acceleration provisions which will be triggered if the closing price of the Company’s common

shares on the Exchange exceeds C$1.10 for 10 consecutive trading days.

The Consideration Shares and any shares acquired on exercise of the Consideration Warrants

will be subject to resale restrictions pursuant to which they may not be resold by the holders

except in accordance with a prescribed schedule. An aggregate of 20% of the Consideration

Units will be released from such resale restrictions every 4 months after closing, with all

Consideration Units being released on the date which is 20 months after closing.

Cautionary Note: The PEA is considered by STS to meet the requirements of a Preliminary

Economic Assessment as defined by Canadian Securities Administrators' National Instrument

43-101 ("NI 43-101") Standards of Disclosure for Mineral Projects. The economic analysis

contained in the technical report is based, in part, on Inferred Resources (as defined in NI 43-

101) and is preliminary in nature. Mineral Resources that are not Mineral Reserves do not

have demonstrated economic viability. There is no guarantee that all or any part of the

Mineral Resource will be converted into a Mineral Reserve. Inferred Resources are considered

too geologically speculative to have mining and economic considerations applied to them and

to be categorized as Mineral Reserves (as defined in NI 43-101). Additional trenching and/or

drilling will be required to convert Inferred Mineral Resources to Measured or Indicated

Mineral Resources. Mineral Resources that are not Mineral Reserves do not have

demonstrated economic viability. There is no certainty that the reserve's development,

production and economic forecasts on which the PEA is based will be realized.
