HIGHLIGHTS

•After-tax NPV5%of $197.1 million and IRR of 34% at $1,250/oz gold
•Low initial capital cost of $130.8 million, with LOM sustaining capital cost of $51.3 million
•LOM gold production of approximately 886,000 ounces at an average gold recovery of 91%
•Average annual gold production of approximately 136,000 ounces
•Average LOM AISC of $754/oz, placing Aurizona in the lowest quartile of the industry average
•Proven and Probable Mineral Reserves of 19.8 million tonnes at 1.52 g/t gold for 971,000 ounces of gold
•FS supports the viability of a mine restart plan with an upgraded 8,000 tonnes per day crushing and grinding circuit to treat all ore types
•First gold pour targeted for year-end 2018

The FS is based on a new mine plan and updated Mineral Reserve estimate and outlines the design of an open-pit gold mine producing on average approximately 136,000 ounces of gold per year, with an initial 6.5-year mine life and significant exploration upside, as demonstrated with recent drill results. Initial capital to fund construction and commissioning is estimated at a modest $130.8 million due to the Company’s ability to leverage significant existing infrastructure in place at the brownfields mine site. Life-of-mine (“LOM”) sustaining capital is estimated at $51.3 million, including closure costs. All-in-sustaining costs (“AISC”) are estimated at $754 per ounce (“$/oz”) over the life of the Project, which is in the lowest quartile of the industry average. The Project demonstrates strong returns in the current gold price environment, with an after-tax internal rate of return (“IRR”) of 34% and an after-tax net present value using a 5% discount rate (“NPV5%) of $197.1 million using a base case gold price of $1,250 per ounce ($254.3 million and 42% at $1,350/oz gold price).

The FS was prepared by Lycopodium Minerals Canada Limited with the support of three other globally recognized engineering firms: AGP Mining Consultants Inc. (“AGP”), SRK Consulting (Canada) Inc. (“SRK”) and BVP Engenharia in partnership with Walm Engenharia e Tecnologia Ambiental. The FS is being summarized into a technical report that will be filed on SEDAR within 45 days, in accordance with National Instrument 43-101 (“NI 43-101”).

Christian Milau, CEO, stated, “The feasibility study outlines a robust, construction-ready, open-pit gold mine that we can rapidly advance to production. This new mine plan supports the original conviction of Trek Mining’s executive team that we are developing a low-cost, high-margin operation that will provide substantial cash generation for the Company, producing on average 136,000 ounces of gold per year at respectably low all-in sustaining costs. Further, based on recent drill results we are confident that we can extend the mine life with exploration success, bringing additional value to both our shareholders and community partners.”

David Laing, COO, added, “This feasibility study reflects extensive engineering and technical work conducted over the last two years. With much of the necessary infrastructure already in place, initial capital to restart Aurizona is significantly less than other similar-size projects, resulting in quick project payback. With the feasibility study complete, we will turn our attention to engineering, procurement and construction activities to get Aurizona back into production.”

BASE CASE HIGHLIGHTS

The 100%-owned Project, located in Maranhão State in northeastern Brazil, is a 223,000-hectare property containing a past-producing open-pit mine and gold processing plant, the Piaba and Boa Esperança gold deposits and numerous exploration targets. The FS provides a compilation of the engineering and geological studies performed in 2016 and 2017, which incorporated the results from drilling conducted in 2015 and additional geotechnical and geochemical site characterization work carried out in 2016 and 2017. FS highlights are summarized in the table below.

CAPITAL & OPERATING COSTS
Initial capital to fund construction and commissioning is estimated at a modest $130.8 million due to the Company’s ability to leverage significant existing infrastructure in place at the brownfields mine site. Most major mine and processing elements are already in place, including a tailings storage facility (“TSF”) and waste dumps, a dedicated power line, camp offices and accommodations, water, roads and communications.


The re-engineered plant includes an entirely new 8,000 tpd crushing and grinding circuit that will allow all known types of mineral bearing rock at Aurizona to be processed through the gold recovery plant. Procurement and construction of the new components and equipment for the mine restart are expected to take up to 18 months, with first gold pour targeted for year-end 2018.

Initial and sustaining capital costs reflect the use of contractor mining, eliminating the need to purchase a new mining fleet.

Initial Capital $M Sustaining Capital $M
Mining 22.5 Mining 10.6
Treatment plant & repairs 49.3 Tailings dam 35.8

Total Direct Operating Costs $628 $28.03 -
Refining & transport $14 - -
Total Operating Costs $642 - -
Royalties $49 - -
Total Cash Costs * $691 - -

* For IFRS accounting purposes, some stripping costs may be capitalized and included in sustaining capital instead of in operating costs.

Mineral Reserves and Resources
Proven and Probable Mineral Reserves are estimated at 971,000 ounces of gold contained in 19.8 million tonnes of ore at a diluted grade of 1.52 g/t of gold. These Mineral Reserves support an initial 6.5-year mine life with excellent potential to expand the reserve base and extend the mine life with exploration success.
