TRISTAR DISCOVERS SIGNIFICANT NEW GOLD REEFS AT CASTELO DE SONHOS
(Scottsdale, AZ) Assay results from reverse circulation (RC) drilling at the Castelo de Sonhos (CDS) gold
project of TriStar Gold Inc. (the “Company” or “TriStar”) continue to show significant intervals in new
holes. “We’re glad that the new drilling is consistent with our exploration target concept ,” says Nick
Appleyard, TriStar’s President and CEO . “We’ve known since last year that we’ve got considerable
potential for growing the resources along the strike of the mineralized conglomerate. But the July results
from in-fill holes in the heart of Esperança South now demonstrate significant upside potential even in
areas where indicated resources were previously reported. Thick intervals running well above the deposit
average point to potential additional resources beyond the pit shell that constrained the 2014 resource.”
Drilling will continue through August into early Septemb er, reaching a planned 120 to 150 RC holes, at
which time a new min eral resource will be estimated, followed by the completion of an initial scoping
study (PEA). The PEA is scheduled to be completed before year end.

(lighter green) that has identified new gold reefs beyond the pit shell previously used to constrain resources.
New reefs identified in heart of the deposit
Figure 1 shows a cros s-section through an area where indicated resources were reported in 2014. On this
section only one drill hole (CSH-12-083) was previously available for resource estimation ; one thick
mineralized interval in this hole controlled the location of the pit she ll within which resources were
reported. New holes within ±50m of this section now make it apparent that the pit shell used for the next
resource update will be larger, and will include thick reefs ( with true thickness >10m) that lie outside the
previous p it shell, with gold grades above the project average. In particular, CSH -17-191 encountered
14m running at an average of 3.2 g/t, with several shorter intervals above 5 g/t.
Grades and thicknesses remain strong in extensions
Figure 2 shows the location of the 93 RC holes that have been completed in the Esperança South and
Center regions of the project. All RC holes are vertical, and drilled to a target depth of 120m. A few holes
were terminated short of their 120m target due to local conditions; any hole th at reaches less than half of
its target length is deemed to be abandoned prematurely, and will be redrilled. Table 1 summarizes the
significant intervals (using a 0.4 g/t cutoff) not previously reported in holes for which assays were
available for more than half of the sample intervals.
Several individual intervals in these new holes run above 10 g/t, with CSH -17-188 reaching 27.8 g/t .
Some of the individual reefs in these new holes are considerably thicker than the deposit average, which
has historically been approximately 4m. With all of the new drilling being vertical, to a target depth of
120m, all of the reported significant intervals are within reach of an open pit. Although diamond drilling
has identified strong mineralization below 120m , the upcomin g PEA will focus only on a stand -alone
open pit mine, and will not address possible longer term potential from underground mining.
Figure 2. Location of new RC drilling at Castelo de Sonhos. RC holes whose significant intervals have been
previously reported are shown in dark green. All the RC holes whose significant intervals are summarized in Table 1
are shown in light green and lie in Esperança South. RC holes with assays pending are shown in blue ; black circles
mark old diamond drill hole locations.

down-hole thicknesses reported here 10-15% longer than true thickness.
2Assays were previously available for the bottom half of Hole 180, where
significant intervals were previously reported. The 21-24m and 45-46m
intervals in this hole are reported here for the first time.
Sample analysis procedures and QA/QC protocols
Sample preparation and analytical work for all of the results reported here were carried out by ALS
laboratories, with sample preparation done at its lab in Goiania, Goias and 1Kg Leachwell assays at its
lab in Lima, Peru; both of these ALS facilities are ISO 9001:2008 and 14001:2004 certified. ALS uses
industry-standard analytical methods and have internal QA/QC programs to monitor the reliability of their
work. Independently of the labs, TriStar runs its own external QA/QC program, using standards, blanks
and duplicates inserted into the sample processing stream at a rate of one per 10 samples.
Update on new Brazilian mining law
On July 25, 2017, Brazilian President Michel Temer signed into law three provisional measures, referred
to as MP 789, MP 790 and MP 791, that a ffect mining projects throughout the country. They take effect
immediately, with Congress being allowed a reasonable period of time to review and amend them.
MP 789 addresses taxation and royalty issues; its principal effect on the Castelo de Sonhos projec t is to
increase the government royalty on gold production from 1% to 2%.
MP 790 modernized the country’s mining code, parts of which had become inconsistent with other
regulations since it was last updated, more than 20 years ago. These changes include: an initiative to align
Brazil’s reporting codes with international reporting codes such as NI 43 -101; the ability to extend the
period during which geology and engineering studies can be done; ending the possibility of a mineral
concession being claimed if the holder of the rights is late in filing certain reports; specific guidance on
mine closure; and changes to the schedule of reporting deadlines. All of these are helpful to TriStar as it
works to advance the Castelo de Sonhos project.
“We welcome all of these changes,” says Nick Appleyard. “They improve transparency in the regulatory
framework, and are designed to relieve companies and the regulators from political pressure. All of this
should make it easier and quicker for us to bring Castelo de Sonhos through the feasibility and permitting
process, and to construct a successful and profitable mine”.
