TRISTAR REPORTS RESULTS OF CASTELO DE SONHOS METALLURGICAL TESTS
Scottsdale, Arizona, TriStar Gold Inc. (the “Company” or “ TriStar”) reports that McClelland
Laboratories (“McClelland”) in Sparks, Nevada has completed the initial metallurgical test-work that will
be used in the Prelim inary Economic Assessment of the Castelo de Sonhos gold project due for
completion in the third quarter of 2017 . Nick Appleyard , T riStar’s President and CEO commented:
“We’re very pleased with these results as they confirm the ability to achieve high recoveries by both
cyanidation and gravity under realistic operating conditions. Over the coming months, we will complete
additional test -work and assess the economics and ti melines of various options to identify the most
appropriate process flowsheet for project development.”
The metallurgical test -work was performed on a bulk sample created from drill core in the Esperança
South region of Castelo de Sonhos with a head grade of approximately 1.5 g/t gold. McClelland assessed
the gold recoveries using gravity concentration and cyanidation, with both sets of tests being done at a
range of commercially reasonable grind sizes.
The gravity recoverable gold (GRG) tests were performed in triplicate on three 15 kg sub -samples from
the bulk sample, at grind sizes that reflect coarse, medium and fine options: 80% passing (P80) 850, 250
and 75 microns. The results, presented in Table 1, demonstrate that most of the gold can be recovered to a
rougher concentrate using gravity methods.

P(80) Gold
Recovery
850 microns 41%
250 microns 73%
75 microns 84%
Gold recovery by cyanidation was assessed through bottle roll tests on four 2 kg sub -samples from the
bulk sample, also at a range of grind sizes typical for a cyanidation process flowsheet. The results,
presented in Table 2, show very high recoveries . Consumption of cyanide and lime were both low, an
additional benefit as this reduces operating costs.

250 microns 93%
150 microns 98%

75 microns 98%
Based on these positive results, TriStar will continue to assess the metallurgical characteristics of the
Castelo de Son hos deposit . Additional test -work will be aimed at establishing standard operating
procedures for crushing and grinding, gold recovery and tailings disposal.
