TRISTAR PROVIDES UPDATE ON ADVANCES AT CASTELO DE SONHOS
(Scottsdale, AZ) TriStar Gold Inc. (the “Company” or “TriStar”) is pleased to provide an update on several
new initiatives underway or recently completed at the 100% owned Castelo de Sonhos gold project located
in Pará State, Brazil.
Highlights
• Field mapping and surface reconnaissance in Esperança East has confirmed gold in panned
concentrates from outcrops, leading to the prioritization of new drilling targets in areas where
resource have not previously been estimated.
• The project site is now connected to the national electrical grid.
• Advanced state-of-the-art metal detection is being tested for ra pidly screening samples for gold
content; if successful, this technology could allow more rapid identification of drill targets this year,
and, in the future, considerably improve grade control and material sorting.
Nick Appleyard, TriStar’s President and CEO. “This is the year when much of the project’s upside is
going to come to the forefront: the resource, our proximity to good infrastructure, our strong
understanding of the geology, and the deposit’s predominantly free gold and sulphide-free, clean and
simple metallurgical characteristics”.
Field mapping and surface reconnaissance in Esperança East
To prioritize drilling targets at Esperança East, TriStar has completed a field mapping and surface
reconnaissance program and conducted a series of tests of rapid manual gravity concentration (“panning”)
to establish the linkage between assay gold grades and gold in pan concentrates.
• Field mapping has produced a better understanding of the details of bedding orientations and
supplied dozens of new measurements of local directions of continuity.
• Pan concentrates are valuable in identifying mineralization in outcrops, and for rapidly determining
whether to extend drilling in reverse circulation holes (holes are deepened beyond the initial target
depth when gold can be identified in pan concentrates from the last few sample intervals).
Esperança East lies on the fault block that separates Esperança South from Esperança Center. Soil sampling,
geophysics and structural geology all point to the likelihood that the conglomerate band in Esperança East
is the “bridge” of gold mineralization that connects the strong mineralization at the north end of Esperança
South to the mineralization at the south end of Esperança Center (see Figure 1).

Esperança South and Esperança Center.
Connection to the national electrical grid
The Castelo de Sonhos project is very close to the major highway that also serves as a corridor for electrical
power. TriStar, in cooperation with local farmers, has participated in the Brazilian federal government’s
rural electrification program. This month, the Castelo de Sonhos project site was connected to the national
grid, and no longer needs to rely on diesel generators.

and operational in April 2018.
Advanced high-precision metal detection technology
• TriStar is undertaking a proof-of-concept study that aims to establish whether high precision metal
detectors are able to screen waste rock from rock with gold mineralization.
In February 2018, TriStar met with Fortress Technology, a Canadian company with production facilities in
Brazil, that specializes in high precision metal detection for the food products industry. With Fortress’
detectors able to measure metallic constituents at the parts -per-billion level, their industrial detectors
clearly have the precision to detect gold at the parts-per-million levels often encountered in modern gold
deposits.

for the lumber industry, similar to a possible future application at Castelo de Sonhos.
In March, TriStar delivered to Fortress’ offices in São Paulo, Brazil, a suite of rock samples and calibration
samples that will serve as the basis for a proof-of-concept study that aims to establish whether high precision
metal detectors are able to screen waste rock from rock with gold mineralization.
Metal detection is possible in this type of paleoplacer deposit, and not so much in other gold deposits as the
vast majority of the rock is non -metallic quartz; there are no sulfides like pyrite that would mask and
complicate the exceptional electrical properties of gold.
TriStar is optimistic that this , or similar, technology might be an innovation that allows more rapid
identification of drill targets this year, and, in the future, better grade control and efficient material sorting.

such as “expects” or “it is expected”, or variations of such words and phrases or statements that certain actions, events or results
“will” occur. Forward looking statements in this press release include, the scope and success of the planned exploration program
at the Castelo de Sonhos project and the Company's opinion that it has clear title to the Castelo de Sonhos property Such forward-
looking statements are based upon the Company's reasonable expectations and business plan at the date hereof, which are subject
to change depending on economic, political and competitive circumstances and contingencies. Readers are cautioned that such
forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause a change in such
