Consolidated Financial Results ($ millions, except per-share amounts)

Consolidated Production Results

Consolidated Sales Results

(1) Q2-2017 and six months June 30, 2017 consolidated production and sales are from the Santander and Caribou mines only. Trevali acquired the Perkoa and Rosh Pinah mines on August 31, 2017.
(2) Please refer to “Use of Non-IFRS Financial Performance Measures” below.
(3) Revenues include effects of settlement adjustments on sales from prior quarters and is calculated on a 100% basis.

Perkoa Mine, Burkina Faso:
Q2 production was 46.2 million pounds (20,940 tonnes) of payable zinc. Metal sales for the quarter was 58.8 million pounds (29,687 tonnes) of zinc for revenue of $62 million. The Q2 operational gross profit was $19.5 million, an increase of 97.2% from Q1, with operational costs all materially decreased on a quarter-to-quarter basis.

Mine output and mill throughput for the quarter were 182,551 tonnes and 176,027 tonnes of ore, respectively. Given the strong performance over the first half of 2018, the Company increased its 2018 zinc production guidance by 9 million pounds (4,080 tonnes) to 164-174 million payable pounds (74,400-78,950 tonnes).

Perkoa Production Results

(2) Revenues include effects of settlement adjustments on sales from prior quarters and is calculated on a 100% basis.

Rosh Pinah Mine, Namibia:

Q2 production was 20.8 million pounds (9,449 tonnes) of payable zinc, 2.1 million pounds (974 tonnes) of payable lead and 28,388 ounces of payable silver. Metal sales for the quarter were 17.5 million pounds (7,946 tonnes) of zinc, 4.4 million pounds (2,006 tonnes) of lead and 54,050 ounces silver for revenue of $21.6 million.

Mine output and mill throughput for the quarter was 159,797 tonnes and 173,082 tonnes, respectively. Performance for the quarter was below expectation; specifically, mine production did not achieve targeted levels due to non-optimal operational practices. Consequently, 2018 production guidance has been reduced by 10 million pounds (4,540 tonnes) to 95-105 million payable pounds (43,100-47,640 tonnes) of zinc. The Company is actively addressing this issue and continues to onboard key skills, advance workforce training, provide operational support and implement compliance tracking.

Exploration Update – Second Quarter:
Trevali’s 2018 exploration program is focused on brownfield and near-mine exploration targets. The primary aim is to expand and discover new mineral resources adjacent to existing mine infrastructure, replace mined inventory, grow sustainable production, extend expected mine life and ultimately, contingent on success, provide production growth optionality to the operations.

The annual exploration program includes approximately 60,000 metres of diamond drilling for surface and underground targeting in-to-near mine resource growth with a minimum committed budget of $13 million.

Exploration and resource conversion drilling totaled approximately 26,500 metres during the quarter.

At Perkoa, 2,900 metres of underground resource expansion drilling continued to return exceptionally high-grade zinc results up to 240 metres below the current modelled mining level and confirms the high-grade mineralization remains open at depth. Highlights include:

• 9.4 metres at 26.6% zinc, including 2.6 metres at 39.3% zinc and 3.3 metres at 31.8% zinc;
• 10.3 metres at 18.7% zinc, including 5.0 metres at 30% zinc;
• 19.6 metres at 16.5% zinc, including 9.1 metres at 23.1% zinc.

The exploration group continues to test the depth extents of Perkoa system and is planning to mobilize a second UG diamond drill rig to site.

Regionally, the Company continues to advance high priority targets along the approximately 25-kilometre strike of the Perkoa Mine Horizon identified to date. Using a multi-disciplinary mineral system approach the Company has identified significant priority VMS targets, intersected semi-massive to massive sulphide mineralization – a first for this frontier district, and identified areas of surface to near-surface gossanous material (evidence of the presence of semi-massive to massive sulphide mineralization).

Initial drill testing of the AF1 target intersected thick zones of VMS alteration (silica – sericite – pyrite) within which semi-massive to narrow massive sulphides occur. Currently interpreted as the top of a VMS system, this is the first VMS and zinc mineralization intersected outside of the Perkoa deposit and is potentially indicative of the presence of a productive VMS belt. Downhole geophysics will be used to vector future drill testing. At the Byrhado prospect, 5 stacked gossan horizons are hosted within a folded package of siliceous felsic volcanics, tuffs and sediments that are cross cut by an intense quartz stockwork. All samples collected to date are highly geochemically anomalous with similar trace element pathfinder geochemistry as the Perkoa deposit. Drill testing will occur in Q4 following the end of the wet season. The Company classifies the target as early stage. Significant drill testing is required and there is no guarantee that base metal sulphides will be intersected in subsequent drill testing.

At Santander, exploration drilling continues to test the Magistral deposit extensions approximately 300 vertical metres below current development, in addition to continuing to extend the emerging Pipe target at depth. Geochemical assay results from second quarter drilling will be released in upon receipt, anticipated in late August – early September. The approximately 45-square-kilometre Santander exploration block remains under-explored and several priority exploration targets will be tested during the second half of the year.

At Rosh Pinah, ongoing underground exploration continues to define the emerging NW extension in the Western Orefield that remains open for expansion. During the quarter the Company re-targeted the deposit from first principals with a focus on the historically mined Eastern Orefield. The exploration initiative identified numerous priority targets in an area previously or largely considered geologically closed. The Company has hired additional dedicated exploration specialists and an initial approximately 10,000-metre discovery drill program will commence in H2. Regional and district targeting continues to advance in the belt.

In the Bathurst Mining Camp, Trevali completed resource definition drilling on its Restigouche deposit in addition to metallurgical and geotechnical drilling on the Murray Brook property with partner Puma Exploration. The results of both programs will facilitate advanced engineering and production studies for future Caribou mill feed. Late in the quarter a 12,000-metre exploration and definition drill program commenced at the Caribou deposit to target the down-dip extensions of the East Limb, Hinge Zone, and the newly discovered CX Zone, all of which remain open for extension.

Use of Non-IFRS Financial Performance Measures
Trevali uses non-IFRS measures such as EBITDA and Cash Operating Costs (per Tonne milled), among other measures. Management uses these measures internally to evaluate the underlying operating performance of the Company for the reporting periods presented. The use of these measures enables management to assess performance trends and to evaluate the underlying business of the Company. We believe that these measures reflect the Company’s performance and are useful indicators of its expected performance in future periods. This data is intended to provide additional information and should not be considered in isolation of or as a substitute for measures of performance prepared in accordance with IFRS.

In this news release, we present EBITDA, which we define as profit attributable to shareholders before net finance expense, foreign exchange gains and losses, income and resource taxes, other income and expense, and depreciation, depletion and amortization. Our calculation of EBITDA may be different from the calculation used by other companies, including our competitors in the mining industry, so our measures may not be comparable to those of other companies.

We also present in this news release Site Cash Operating Cost (per Tonne milled), which includes mine operating production expenses such as mining, processing, administration, indirect charges such as surface maintenance and camp expense, and inventory stock movement divided by tonnes milled. Site Cash Operating Cost (per Tonne milled) does not include smelting and refining, distribution (freight), royalties, by-product revenues, depreciation, depletion, amortization, reclamation, and capital sustaining and exploration expenses.
