300 Metre Step-out Hole Intersects 3.90 Grams per Tonne Gold Over 11.0 Metres

May 17, 2017 – Vancouver, BC – Trek Mining Inc. (TSX-V: TREK) (“Trek” or “the Company”) is pleased to announce that initial drilling in Piaba West has intersected 3.90 grams per tonne gold (“g/t Au”) over 11.0 metres in a step-out drill hole located 300 metres along strike of the currently defined Piaba gold deposit at its 100%-owned Aurizona Gold Mine (“Aurizona”) in Brazil. Results from the initial 18 shallow holes totalling 1,594 metres have successfully demonstrated that significant gold mineralization persists below the shallow, westernmost reserve pit and that the Piaba gold deposit extends along strike at least 300 metres to the west.

Drilling highlights include:
•3.90 g/t Au over 11.0 m in BRAZP575
•1.95 g/t Au over 4.0 m and 2.17 g/t Au over 5.0m in BRAZP580
•28.16 g/t Au over 4.0 m including 112 g/t over 1.0 m in BRAZP582
•2.63 g/t Au over 9.0 m in BRAZP572
•0.99 g/t Au over 15.0 m in BRAZP571
•1.22 g/t Au over 33.0 m including 2.27 g/t Au over 11.0 m in BRAZP569
“Encountering ore grade intercepts along strike is exactly the result we were looking for,” said Scott Heffernan, EVP Exploration of Trek. “Drilling at Piaba West is ongoing and will further test the continuity of mineralization along strike from current gold reserves in the Piaba gold deposit.”

Drill hole BRAZP575, located 300 metres beyond the westernmost edge of the existing Piaba pit, encountered 3.90 g/t Au over 11.0 metres from 49 metres down hole. BRAZP576 was collared a further 100 metres west of BRAZP575 and ended in mineralization grading 0.71 g/t gold over 6.0 metres at a depth of 110 metres, indicating that mineralization continues for an additional 100 metres along strike but may dip to the southwest. •For a complete table of the Company’s 2017 exploration drill results to date, click here

“These initial results support our expectation that the Piaba gold deposit continues at depth and along strike to the west,” said Christian Milau, CEO of Trek. “Successful infill drilling below the western end of the pit and in the identified extension should lead to an increase in Aurizona gold resources and an extension of the mine life.”
Current gold reserves at Aurizona are contained primarily within the Piaba gold deposit which remains open along strike and to depth. Piaba West is a potential 900-metre long extension of the Piaba gold deposit and is the first of several near-mine targets to be drilled as part of the Company’s planned 30,000-metre 2017 exploration program at Aurizona. Trek’s immediate priority is to follow the mineralization along strike and down plunge, and to increase drill hole density below the western edge of the current reserve pit and the initial 300-metre extension. An additional 600 metres of westerly strike will be tested upon receipt and interpretation of a recently completed 38,000 line-km airborne magnetic and radiometric survey.
