September 12, 2017 – Vancouver, BC – Trek Mining Inc. (TSX-V: TREK) (“Trek Mining” or “the Company”) is pleased to announce that exploration drilling at the Company’s 100%-owned Aurizona Gold Mine (“Aurizona”) in Brazil has intersected two new zones of significant gold mineralization at the Genipapo target, east of the Piaba gold deposit.

Drilling highlights include: •3.28 grams per tonne gold (“g/t Au”) over 4.0 metres (“m”) in BRAZD545
•1.89 g/t Au over 13.0 m including 5.57 g/t Au over 3.0 m in BRAZD546

The Genipapo target, located east and north of the Piaba gold deposit, measures several square kilometres in area and covers numerous northwest-southeast trending gold-in-soil anomalies. Five diamond drill holes totalling 1,009 m were drilled to test the target area. Drill hole BRAZD545 intersected 3.28 g/t Au over 4.0 m. Drill hole BRAZD546, collared approximately 500 m south of BRAZD545, intersected 1.89 g/t Au over 13.0 m including 5.57 g/t Au over 3.0 m. The two drill holes, located approximately 1,000 m east of the Piaba gold deposit reserve pit limit, tested the northern and southern flanks of a large northwest trending gold-in-soil anomaly measuring approximately 500 m by 1,000 m.

"Drilling in the Genipapo area was designed to test new concepts derived from the integration of airborne geophysics with our existing geoscience database,” said Scott Heffernan, EVP Exploration of Trek Mining. “To have encountered significant, new gold mineralization with this first test is very encouraging and clearly demonstrates the value of continuing our exploration efforts in the area.”

Trek Mining has recently commenced an aggressive second phase of exploration drilling at Aurizona and now has five diamond drill rigs working to complete an approximately 12,000 m drill campaign. The focus of the current drill campaign includes testing several high-potential near-mine targets, including follow-up drilling at Genipapo, and additional infill drilling at Piaba West to facilitate incorporation of Piaba West mineralization into the Aurizona resource and reserve base.

About the Aurizona Gold Mine

The current reserve and resource model for Aurizona outlines a 6.5-year mine life based on reserves identified in the Piaba and Boa Esperança pits. Gold mineralization is structurally controlled by subvertical, strike-slip shear zones occurring along significant lithological contact between metavolcano-sedimentary units and intrusive rocks. Host rocks are hydrothermally altered quartz diorite and plagioclase-quartz diorite rocks. The mineralization style is disseminated stockwork and vein-hosted sulphides and gold within a silicified shear zone. Gold mineralization at Piaba West is hosted in a northern, hanging wall sequence composed mainly of diorite and quartz diorite intrusives with subordinate dacitic volcanics. Additional information about Aurizona is available in the July 2017 “Feasibility Study on the Aurizona Gold Mine Project” that is available on the Company’s website and on SEDAR at www.sedar.com.
