TriStar Gold Issues Corporate Update for the Castelo de Sonhos Project

SCOTTSDALE, Dec. 13, 2018 - TriStar Gold Inc. (the “Company” or “TriStar”), is excited to provide the following recap of the major milestones recently accomplished and a corporate update with respect to the planned activities for 2019.

Key milestones from 2018 include the following:

• Successfully completed the planned 5,000m of drilling on time and on budget
• Updated mineral resource in September (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
  - Details available in the September 17th 2018 press release entitled “35% increase in resources at Castelo de Sonhos as preliminary economic assessment begins"

• Published the first ever preliminary economic assessment (“PEA”) of the Castelo de Sonhos deposit

• Internal rate of return, pre-tax of 51%, post-tax of 43% (using a gold price of $1250 per ounce)
• 1.9 year payback period
• All in sustaining cost of $687/oz

• In-spite of adverse equity markets, completed two private placements for gross proceeds of Can $4.9 million

Nick Appleyard, TriStar’s President and CEO stated: “This year we have achieved some amazing milestones for this project. The mineral resource has continued to grow as anticipated for this style of deposit, but it’s not just the size, with 700,000 ounces in the indicated category it is also growing in confidence. The independent PEA results are exceptional and exceeded our internal expectations. Our plan now is to keep going, this means drilling for more resources, continuing to de-risk the project and continuing to achieve major milestones with this exceptional deposit. To date, we have only drilled about 60% of the open-pit target so there is still lots to learn and hopefully value to discover. It’s also worth noting that the recent political elections in Brazil have resulted in a new president who promises to be favorable to foreign investment and project advancement whilst maintaining his hardline against corruption”.

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.

2019 Planned Activities at CDS

Subject to available financing, in 2019 the Company plans to continue to drill with the aim of both expanding resources and upgrading resource classification. The baseline social and environmental work required for possible future mine permitting will also start.
