51% IRR from PEA at TriStar Gold’s Castelo de Sonhos Project

(Scottsdale, AZ), On behalf of TriStar Gold Inc. (the “Company” or “TriStar”), GE21 Consultoria Mineral

Ltda (“GE21”) of Belo Horizonte, Brazil, has completed the Preliminary Economic Assessment (“PEA”)

for the Company’s Castelo de Sonhos gold project in southern Pará State, Brazil.

Key highlights of the PEA include the following:

• Life-of-mine recoverable gold of 1.1 million ounces (“Moz”)

• Internal rate of return pre-tax of 51%

• Cash cost of $660

• All in sustaining cost (“AISC”) of $687

Nick Appleyard, TriStar’s President and CEO stated: “This study now shows a robust, low cost base case

for the Castelo de Sonhos gold project. With payback in less than two years and an average production of

nearly 160,000 ounces per year for the first four years, the remarkable potential of this project is coming

into focus. We intend to complete further drilling in 2019 with an aim to further increase the mineral

resource estimate”.

The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too

speculative geologically to have the economic considerations applied to them that would enable them

to be categorized as Mineral Reserves. There is no certainty that the economic results described in

the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated

economic viability.

Preliminary Economic Assessment

The PEA for Castelo de Sonhos has assumed the use of a contract mining company, to conduct open pit

mining using technology equipment readily available in Brazil and elsewhere in the World. The open-pit

mine is designed assuming 55⁰ slope angle, 8m bench height and a 10% access ramp.

The material for pro cessing will be crushed and then ground to 150 microns before being leached using

Carbon-in-pulp (“CIP”) . Process t ailings will be discharged to an engineered facility designed to

international standards of safety.

The economic analysis includes allowances for milestone payments due under the original purchase

agreement, as well as mine closure and remediation.

Mineral resource

The PEA is based on the previously announced mineral resource as shown below:

Mineral Resources (above a 0.3 g/t cut-off) of:

Indicated: 17.7 million tonnes at 1.2 g/t, containing 0.7 Moz of gold

Inferred: 39.8 million tonnes at 1.0 g/t, containing 1.3 Moz of gold

AT CASTELO DE SONHOS AS PRELIMINARY ECONOMIC ASSESSMENT BEGINS”
