TORONTO, Aug. 13, 2018 /PRNewswire/ - Sierra Metals Inc. (TSX:SMT)(BVL:SMT)(NYSE American:SMTS) ("Sierra Metals" or the "Company") today reported revenue of $62.7 million and adjusted EBITDA of $28.9 million on throughput of 602,087 tonnes and metal production of 4.7 million silver equivalent ounces, 24.5 million copper equivalent pounds, and 55.3 million zinc equivalent pounds for the three month period ended June 30, 2018.

During Q2 2018 the Company achieved record quarterly ore throughput from both the Yauricocha and Bolivar Mines, continuing the successful production increases realized during the last five quarters. Consolidated production of Copper increased 62% to 8.6 million pounds, silver increased 12% to 0.7 million ounces, lead decreased 16% to 7.1 million pounds, zinc increased 11% to 20.3 million pounds and gold increased 38% to 1,814 ounces compared to Q2 2017.

During Q2 2018, the Company released encouraging Preliminary Economic Assessments studies ("PEA's") for all three Mines, demonstrating positive economics and supporting potential future operational production increases. Development at all three Mines will continue with an objective of progressing the resource increases at the Cusi Mine, as well as the reserve and resource increases at the Yauricocha and Bolivar Mines into the mine plans. Additionally, continued exploration programs at all three Mines are expected to further increase reserves and resources at all mines which benefit future growth plans.

Igor Gonzales, President and CEO of Sierra Metals stated: "I am very pleased with our strong Q2 2018 results which builds upon our solid first quarter results.  The Company is realizing positive returns on our capital investments and our operational improvement efforts.  This can be noted through improving operating performance and strengthening of our asset base in addition to improved cash flow and increases to mineral reserves and resources at each of our mines.

Yauricocha continues to perform well with sequential record throughput in the second quarter. Additionally, despite lower realized metal prices in the second quarter, Yauricocha still contributed to higher revenue and improved net production revenue per tonne representative of the successful capital investments made. At Bolivar, the effects of the Mexico turn-around program are very noticeable, we achieved record throughput with a 5% increase over Q1-2018 and continue to work towards our goal of 3,500 tonnes per day by year end. We have again achieved lower all-in sustaining costs in the second quarter, which remain below guidance. At Cusi, we are progressing on the ramp up of tonnage and realized quarter over quarter improvements. We continue to campaign development ore from the Santa Rosa de Lima zone with increasing throughput rates, while selectively mining structures in the older part of the mine.  We are pleased to report that the Company reached the existing mill's production capacity of 650 tonnes per day in late Q2-2018. The addition of another ball mill in the second half of 2018 will see the capacity increase to approximately 1,200 tonnes per day in early 2019."

He concluded, "Sierra Metals balance sheet remains strong with solid liquidity to meet its operational and growth expenditure requirements.  Management maintains its optimism for the remainder of the year as the groundwork for further improvements has been laid through the implementation of best operational practices. Our recently completed, positive PEA's at all three Mines demonstrate the robust growth opportunities for the Company. Additionally, aggressive, brownfield exploration programs focused on high value targets are being executed which could lead to further significant growth in mineral reserves and resources at all of our Mines, which will add to the value of our assets now and in the years ahead."

The following table displays selected financial and operational information for the three and six months ended June 30, 2018:

Q2 and H1 2018 Financial Highlights

Revenue from metals payable of $62.7 million in Q2 2018 increased by 29% from $48.6 million in Q2 2017. Higher revenues are primarily attributable to the 19% increase in throughput, the increase in copper, and gold head grades, and higher recoveries for copper, lead, and gold at Yauricocha; and the increase in the prices of copper (21%), lead (10%), zinc (15%), and gold (2%) in Q2 2018 compared to Q2 2017; the 41% increase in throughput, higher copper and silver head grades, copper and gold recoveries, and the higher copper price resulted in Bolivar's revenues being 61% higher than Q2 2017; and the 95% increase in throughput, and higher silver recoveries resulted in Cusi's revenues being 102% higher than Q2 2017.

Yauricocha's cash cost per zinc equivalent payable pound was $0.50 (Q2 2017 - $0.48), and AISC per zinc equivalent payable pound of $0.72 (Q2 2017 - $0.76). The decrease in the AISC per zinc equivalent payable pound for Q2 2018 compared to Q2 2017 was a result of lower sustaining capital expenditures, while zinc equivalent payable pounds and cash costs remained consistent; this was partially offset by slight increases in general and administrative costs.

Bolivar's cash cost per copper equivalent payable pound was $1.14 (Q2 2017 - $1.42), and AISC per copper equivalent payable pound was $1.90 (Q2 2017 - $2.60) for Q2 2018 compared to Q2 2017. The decrease in the AISC per copper equivalent payable pound during Q2 2018 was due to the increase in copper equivalent payable pounds resulting from higher throughput, copper and silver head grades, and copper and gold recoveries; as well as a decrease in sustaining capital expenditures, as there were additional mine development costs, and various equipment purchases made by the Company during the Q2 2017 in an effort to improve equipment availability and increase tonnage.

Cusi's cash cost per silver equivalent payable ounce was $12.78 (Q2 2017 - $18.90), and AISC per silver equivalent payable ounce was $19.98 (Q2 2017 - $45.06) for Q2 2018 compared to Q2 2017. AISC per silver equivalent payable ounce decreased due to higher silver equivalent payable ounces resulting from higher throughput and higher silver recoveries.

Adjusted EBITDA⁽¹⁾ of $28.9 million for Q2 2018 increased 64% compared to $17.6 million in Q2 2017. The increase in adjusted EBITDA in Q2 2018 was primarily due to the $14.1 million increase in revenues discussed previously.

Cash flow generated from operations before movements in working capital of $29.5 million for Q2 2018 increased 70% compared to $17.4 million in Q2 2017. The increase in operating cash flow is mainly the result of higher revenues generated and higher gross margins realized.

Net income (loss) attributable to shareholders for Q2 2018 was $10.8 million (Q2 2017: $(2.8) million) or $0.07 per share (basic and diluted) (Q2 2017: $(0.02)).

Cash and cash equivalents of $21.8 million and working capital of $2.9 million as at June 30, 2018 compared to $23.9 million and $(6.8) million, respectively, at the end of 2017. Cash and cash equivalents have decreased by $2.1 million during H1 2018 due to $27.0 million of operating cash flows, and $5.0 million drawn down from a short term revolving line of credit, being offset by capital expenditures incurred in Mexico and Peru of $(24.0) million, repayment of loans, credit facilities and interest of $(8.3) million, dividends paid to non-controlling interest shareholders of $(1.6) million. Included in the $27.0 million of operating cash flows were negative changes in non-cash working capital items of $11.1 million due to the increase in trade receivables as at June 30, 2018.

Mine development at Bolívar during Q2 2018 totaled 1,025 meters. Most of these meters (550m) were developed to prepare stopes for mine production. The remainder of the meters (475) were related to the deepening of ramps and developing service ramps to be used for ventilation and pumping.

During Q2 2018, at the Cusi property, mine development totaled 1,652 meters, and 960 meters of infill drilling was carried out inside the Mine, and 9,455 meters drilled from surface.

Exploration Update

Peru:
During Q2 2018, the Company drilled 45 holes totaling 8,366 meters at Yauricocha. The drilling included the following:

Exploration Drilling:

• Contacto Oriental (Level 1070): 4 holes totaling 588 meters have intercepted positive results regarding the continuity of the orebody at depth;
• Contacto Sur Medio Oeste (Level 1070 Central Mine Zone): 2 horizontal holes totaling 316 meters to explore possible mineralize orebodies;
• Esperanza (Level 1070 Central Mine Zone): 2 holes totaling 1,507 meters with the objective of verifying the continuity of the orebody dimensions to the 1570 level;
• Esperanza - Cuye (Level 1070 Central Mine Zone): 1 hole totaling 859 meters (246 meters during Q2 2018) with the objective of exploring the area between Cuye and Esperanza, an area which has provided evidence of a potential porphyry system;
• Cuye (Level 1070 Central Mine Zone) – 2 long holes totaling 1,113 meters with the objective of exploring the continuation of the orebody at depth, which project the dimensions of the orebody to extend to the 1570 level;
• Escondida Norte (870 Level Cachi Cachi) – 1 hole totaling 243 meters which intercepted mineralized oxide zones down to the 1120 level; we are continuing to drill this area;

Definition Drilling:

• Antacaca (Level 1070): 4 holes totaling 210 meters to provide more certainty and definition of the orebody;
• Esperanza (Level 970): 10 holes totaling 1,410 meters to define the continuity of mineralization of the orebody; which were executed from the 970 level;
• Catas (Levels 1020 & 1070): 8 holes totaling 799 meters to further define the orebody;
• Butz (1070 Level): 9 holes totaling 862 meters to further define the orebody, which intercepted polymetallic mineral;
• Mascota (1170 Level): 2 holes totaling 459 meters in the polymetallic area of the orebody to further define it; these holes intercepted stretches of economic mineral;
• During Q2 2018, surface exploration was continued in the southern end of the Central Mine Zone, mainly in the areas of the Chonta Fault (Yauricocha II), where diamond drilling will be carried out.

Bolivar

• At Bolívar during Q2 2018, 7,403 meters were drilled from surface as well as diamond drilling within the mine. 2,026 meters were drilled within the mine in the El Gallo zone, and 5,377 meters of surface diamond drilling divided between Bolivar Northwest, Bolivar West and Cieneguita. This drilling was performed to explore the extension of the orebody to the North and West, exploring the skarn orebody with semi-massive magnetite, and disseminated nodules of chalcopyrite. There are also greenfield exploration targets being explored to analyze geological anomalies and the continuity of the orebody Americanos to the west.

Cusi:

• During Q2 2018 the Company drilled 960 meters inside the mines to verify the continuity of the orebodies and support development work on the various veins and 10,416 meters on surface.
• On June 29, 2018 the Company announced the definition of a 40-metre wide, high grade silver stockwork area which remained open to depth and width within the Santa Rose de Lima zone. Subsequent drilling has since extended the width of that zone to 50-meters from 40-meters with the area still remaining open to depth and along strike.
