Trek Mining Announces First Quarter Results

VANCOUVER, BC--(Marketwired - May 30, 2017) - Trek Mining Inc. (TSX VENTURE: TREK) ("Trek Mining" or "the Company") is pleased to announce that its financial results for the first quarter ended March 31, 2017 and the accompanying Management's Discussion and Analysis are available for download on the Company's website at www.trekmining.com and at www.sedar.com. All dollar amounts are in United States dollars.

Quarterly highlights and recent developments

• Completed the acquisition of Luna Gold Corp.
• Raised $61.4 million (approximately C$81.9 million), net of finance fees, in a private placement and brokered financing
• Initial drill results confirmed extension of mineralization along strike from existing reserves at Aurizona
• Secured two additional exploration concessions at Warintza (total property size now 26,777 hectares)
• Cash and short-term investments at end of Q1-2017 of $85.7 million (approximately C$110 million)

On March 31, 2017, the Company completed the acquisition of Luna Gold Corp. and rebranded as Trek Mining Inc. The combined company is well-funded with a diverse portfolio of assets, anchored by near-term production at its cornerstone 100%-owned Aurizona Gold Mine ("Aurizona") in Brazil. Trek expects to complete a feasibility study for Aurizona in June 2017 and hopes to initiate mine construction in Q3, with the objective of pouring gold at Aurizona by year-end 2018. Aurizona is expected to produce on average 150,000 ounces of gold per year during its first five years of production.

Concurrent with development activities, exploration is underway at Aurizona to test both near-mine and district targets. In its initial drill program on the Piaba West target, the Company intersected 3.90 grams per tonne gold over 11.0 metres in a step-out drill hole located 300 metres along strike of the currently defined Piaba gold deposit. This intersection, along with additional results from 18 shallow holes drilled on the Piaba West target, confirmed that mineralization extends at least 300 metres along strike to the west and also at depth below the western extent of the existing pit (see Trek's May 17, 2017 news release). The Company will continue to drill along strike to test the western extent of mineralization and will also infill existing drilling, with the expectation of adding to the resource base and extending the mine life.

At the Company's other projects, production ramp-up at the Peru-based Koricancha Mill continues with over 2,000 ounces of gold poured in Q1-2017. The Company also expanded its Warintza project in Ecuador with two additional exploration claims, in addition to the three announced in January 2017. The five claims received in 2017 are free of nongovernmental royalties. The Company has increased its outreach programs with various stakeholders to establish the relationships and social support required to recommence exploration activities at this promising copper-molybdenum property.

At March 31, 2017, the company had $85.7 million (approximately C$110 million) of cash and short-term investments and no cash debt, with a working capital balance of $87.8 million.
