South Star Mining Submits Environmental Permitting Documents for Pilot Plant

Operations at the Santa Cruz Graphite Project

Toronto, ON, January 6, 2020 – South Star Mining Corp. (‘South Star’ or ‘the Company’) (TSX-V: STS) is pleased

to announce that it has completed and formally submitted the en vironmental permitting documents to the

responsible permitting consortium for the construction and oper ations of a 5000 tonne/year pilot plant facility

at the Santa Cruz Graphite Project.

Richard Pearce, President and CEO of South Star, commented: “We are pleased to have completed another big

step forward in our march towards production. In short order w e will also be submitting the trial mining

licensing documents (Guia de Utilização - GU) to the National Mining Agency (ANM). The pilot plant operations

will provide short-term cash flow from operations and allow us to qualify bulk samples in the marketplace and

establish future, firm offtake agreements. We have been working diligently to develop commercial

relationships with key players, bo th in Brazil and internationa lly, and have received excellent feedback on our

sample materials shipped to date. We will monitor closely the permitting process and will be using the first half

of 2020 to get the financing in place to construct and commissi on the pilot plant facilities. Construction is

expected to take approximately 8-10 months. We are excited to be moving past our project development stage

and focusing all our efforts and attention on near-term construction, commissioning and production.”

12 volumes totaling more than 800 pages evaluating environmenta l and socioeconomic impacts of the project

were included in the submittal, including:

x General project description and impact study;

x Fauna and flora inventories and baseline studies;

x Construction implementation and waste management planning;

x General closure and reclamation planning;

x Solids waste management planning;

x Environmental risk assessment procedures;

x Ongoing environmental monitoring programs;

x Emergency action plans;

x Ongoing educational and community relations planning.

The goal of the pilot plant operations is to prove the economic and technical viability of the Project at a small

scale, while also allowing the Company to produce and qualify l arge scale samples (1-20t) in the marketplace.

The pilot plant will allow the Company to test and optimize the flowsheet, develop the key commercial

relationships and optimize the production of products demanded in the marketplace, given the inherent, high-

quality nature of the concentrates produced to date.

The 5000 tpy concentrate pilot plant is Phase 1 of the proposed path to production and includes a small-pit

pilot processing plant, as well as filtered tails technology, waste storage facility for co-disposal of wasterock and

filtered tails, and civil infrastructure. The experience gained and commercial relationships established from

Phase 1 operations will then be used to scale up the operations as part of the Phase 2 expansion plan. The

Phase 2 production facility will be similar in layout and proce ss technology but will be able to produce 25,000

tpy of high-quality concentrate. The upcoming Prefeasibility St udy (PFS) results, expected in January of 2020,

will present the detailed design of the Phase 1 facilities alon g with the PFS level design for the Phase 2 facilities

and the maiden reserve estimate.

The Santa Cruz Graphite Project is located in Southern Bahia in the third largest graphite producing region in

the world with over 70 years of continuous mining. The Project has at surface mineralization in friable

materials, and successful large-scale pilot plant testing (>30t ) has been completed. The results of the testing

show approximately 65% of Cg conc entrate is +80 mesh with good recoveries and 95-99% Cg. With excellent

infrastructure and logistics, South Star is carrying its development plan towards production projected at the end

of 2020.
