STRONG RESULTS ACCELERATE TRISTAR GOLD’S CASTELO DE SONHOS PROJECT,

PRELIMINARY ECONOMIC ASSESSMENT BEGINS

(Scottsdale, AZ) The most recent batches of assays from drilling at the Castelo de Sonhos (CDS) gold

project of TriStar Gold Inc. (the “Company” or “TriStar”) have accelerated the project’s development

schedule; these include:

• 23m @ 1.19 g/t from 64-87m in RC-18-324 at Esperança South (Figure 1), including

− 6m at 2.20 g/t from 64-70m

− 3m at 3.24 g/t from 80-83m

• 19m @ 0.50 g/t from 36-55m in RC-18-322 at Esperança East

• 5m @ 5.06 g/t from 62-67m in RC-18-322 at Esperança East, including

− 1m at 23.14 g/t from 62-63m

• 8m @ 1.14 g/t from 5-13m in CSH-18-293 at Esperança South, including

− 3m at 2.54 g/t from 10-13m

With all holes drilled vertically, and reefs dipping at 20 to 30, true widths are approximately 90% of the

downhole intersection lengths.

“Frankly, we didn’t expect to be at this point this soon,” said Nicholas Appleyard, President/CEO of TriStar.

“Two years ago, we published the science and data analysis that gave us confidence that CDS warranted

development, and we u ndertook drilling programs to expand the mineral resource to the point where a

preliminary economic assessment (PEA) would evaluate the potential profitability of an open-pit mine. We

expected to be moving to a PEA near the end of 2018, but our evaluation of Q2 drilling results convinces

us to launch the PEA now, ahead of schedule.”

Requests for proposals have now been sent to a short-list of engineering companies for the completion of

an updated mineral resource estimate in Q3, a PEA in Q4, and the associated independent 43-101 technical

reports.

Drilling

All assays have now been received for the 34 reverse circulation holes (3,972m) and 8 core holes (960m),

drilled so far in 2018 (see Figure 1). Of the ten holes in the final batch of assays, all had well-mineralized

significant intersections, and nine had multiple significant intersection s. In three of the holes , the total

thickness of the significant intervals exceeded 20m. These results exceed expectations and add confidence

to the geological understanding of CDS.

The tabulation of drilling results maintained by the Company on its website here has been updated to

provide all information available to date on drill hole locations and significant intervals.
