Sierra Metals Inc. Reports 2018 Consolidated Financial Results

28.03.2019  |  Business Wire
- Including $90.1 Million of Operating Cash Flows before Movements in Working Capital

- Conference Call March 29, 2019 at 10:30 Am (EDT)

Sierra Metals Inc. (TSX:SMT) (BVL:SMT) (NYSE American:SMTS) (“Sierra Metals” or the “Company”) today reported revenue of $232.4 million and adjusted EBITDA of $89.8 million on throughput of 2,325,288 tonnes and metal production of 18.0 million silver equivalent ounces, 95.2 million copper equivalent pounds, and 215.1 million zinc equivalent pounds for the year ended December 31, 2018.

During 2018, the annual consolidated production of silver, copper, zinc and gold increased 17%, 27%, 1%, and 25%, respectively, while annual consolidated lead production decreased 7% compared to 2017. The Company achieved record consolidated quarterly ore throughput during Q4 2018, as well as record quarterly ore throughput from the Bolivar and Cusi Mines. These results continued the Company’s successful production increases realized during the first three quarters of 2018, which resulted in strong annual consolidated production figures.

Metal production at Yauricocha increased 14% in Q4 2018 compared to Q4 2017 due to 5% higher ore throughput, higher head grades of all metals, except zinc, and higher lead and gold recoveries. At Bolivar, 20% higher ore throughput, and higher silver and gold head grades resulted in a 16% increase in copper equivalent pounds produced in Q4 2018 compared to Q4 2017. The Cusi Mine realized a 258% increase in throughput which resulted in a 70% increase in silver equivalent ounces produced during Q4 2018 compared to Q4 2017.

Igor Gonzales, President, and CEO of Sierra Metals stated: “I am very pleased with the Company’s performance during Q4 and full year 2018. Despite challenges such as harsh weather events in Q3 at the Bolivar Mine, the Company generated positive cash flow at its three operating Mines, realizing a 13% increase over 2017, and our production results were solid with year over year increases to the consolidated production of all metals except lead. The Company continues to realize positive returns on the capital investments and operational improvement efforts at all our Mines. This is best demonstrated through our improving operating performance, strengthening of our asset base, significantly lower all-in sustaining costs and continued strong cash flow.

2019 will be an important year for the Company as we begin to ramp up production in Mexico. Most equipment is in place at Bolivar for the Mill Expansion and the Cusi Mill is also closer to completion. The development in both Mexican Mines continues with a goal of increasing production volume and recoveries which are expected to support higher metal production starting in Q2 2019. We continue to modernize and improve all our Mines, implementing best operational practices. These improvements are expected to allow for the Company to increase metal production over the course of the coming year. Our Company-wide ongoing brownfield exploration programs should also lead to further significant growth in reserves and resources, which will add to the value of our assets during the year ahead.

The 2019 Capex budget of $83 million provides for the Company’s extensive growth plans. Similar to previous Capex programs, these are investments which will provide the Company with significant returns on the capital invested and continue to be a very efficient use of capital, when considering the production and resource growth that they will deliver to Company and its shareholders. The 2019 Capex program is expected to be funded through 2019 EBITDA as well as existing cash, nevertheless, a new US$100 million credit facility recently put in place provides the Company with ample flexibility to make these prudent investments.

He continued, “Sierra Metals’ balance sheet remains strong with the liquidity needed to meet our operational and growth expenditure requirements. The Company is on track for further growth in 2019 based upon positive PEA studies released earlier this year, demonstrating robust growth opportunities for the Company at all Mines. We continue working on Life of Mine plans which are expected to be completed in mid-2019. Additionally, NI 43-101 Technical Reports are expected to be completed for the Yauricocha Mine by the end of Q2 2019 and for Bolivar and Cusi Mines by the end of Q4 2019, this will also include a maiden reserve estimate for the Cusi Mine. We are very optimistic that these updated reports will provide for additional reserves and resources at all Mines.”

(2) This is a non-IFRS performance measure, see Non-IFRS Performance Measures section of the MD&A.

Revenue from metals payable of $232.4 million in 2018 increased by 13% from $205.1 million in 2017. Higher revenues are primarily attributable to the 8% increase in throughput, and the higher head grades and recoveries for copper and gold at Yauricocha in 2018 compared to 2017; the 16% increase in throughput, higher silver and gold head grades, and higher gold recoveries resulted in Bolivar’s revenues being 17% higher than 2017; and the 112% increase in throughput, and higher silver recoveries resulted in Cusi’s revenues being 88% higher than 2017; the increase in revenues were realized despite decreases in the prices of silver (9%), lead (4%), and zinc (1%), which copper prices increased by 5% and gold prices were consistent with 2017.

Yauricocha’s cash cost per zinc equivalent payable pound was $0.52 (2017 - $0.50), and AISC per zinc equivalent payable pound of $0.73 (2017 - $0.78). The decrease in the AISC per zinc equivalent payable pound for 2018 compared to 2017 was a result of lower sustaining capital expenditures and higher zinc equivalent payable pounds, while cash costs remained consistent; this was partially offset by slight increases in general and administrative costs. These cost decreases were realized despite a $2.0 million increase in labor costs, due to the Company’s union agreement and a salary adjustment to bring the 2018 salaries in line with the current market rates. The payment was made during November and December 2018 but retroactive to the entire year’s salaries. Going forward these costs will be amortized over the entire year for 2019. The union was formed in July 2017 and has grown to 406 workers at the end of 2018, equivalent to approximately 60% of the Company’s workforce, representing the majority of the mine employees.

Bolivar’s cash cost per copper equivalent payable pound was $1.44 (2017 - $1.49), and AISC per copper equivalent payable pound was $2.13 (2017 - $2.70) for 2018 compared to 2017. The decrease in the AISC per copper equivalent payable pound during 2018 compared to 2017 was due to the increase in copper equivalent payable pounds resulting from higher throughput, higher silver and gold head grades and higher gold recoveries, as well as a decrease in sustaining capital expenditures.

Cusi’s cash cost per silver equivalent payable ounce was $15.71 (2017 - $15.37), and AISC per silver equivalent payable ounce was $22.09 (2017 - $33.90) for 2018 compared to 2017. AISC per silver equivalent payable ounce decreased due to higher silver equivalent payable ounces resulting from higher throughput, higher silver recoveries, lower treatment and refining charges, and lower sustaining capital expenditures.

Adjusted EBITDA(1) of $89.8 million for 2018 increased 11% compared to $81.0 million in 2017. The increase in adjusted EBITDA in 2018 was due to the increase in revenues realized at all three Mines during 2018, mainly the result of higher throughput.

Cash flow generated from operations before movements in working capital of $90.1 million for 2018 increased compared to $79.8 million in 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 2018 was $18.8 million (2017: $(4.6) million) or $0.12 per share (basic and diluted) (2017: $(0.03)). The net loss incurred in 2017 included a $4.4 million non-cash loss on the distribution of Cautivo Mining Inc. assets to Sierra shareholders.

Cash and cash equivalents of $21.8 million and working capital of $(8.3) million as at December 31, 2018 compared to $23.9 million and $(6.8) million, respectively, at the end of 2017. Cash and cash equivalents have decreased by $2.0 million during 2018 due to $61.9 million of operating cash flows, and $10.0 million drawn down from a short term revolving line of credit, being offset by capital expenditures incurred in Mexico and Peru of $(49.3) million, repayment of loans, credit facilities and interest of $(21.5) million, dividends paid to non-controlling interest shareholders of $(2.9) million.

Project Development

Mine development at Bolívar during Q4 2018 totaled 1,136 meters. Most of these meters (553m) were developed to prepare stopes for mine production. The remainder of the meters (583m) were related to the deepening of ramps and developing service ramps to be used for ventilation and pumping in the El Gallo Inferior orebody.

During Q4 2018, at the Cusi property, mine development totaled 1,059 meters, which included 25 meters of ramp development at the Santa Rosa de Lima Zone; the rest of the development related to stope preparation in various zones within the Mines.

Exploration Update


During Q4 2018, the Company drilled 58 holes totaling 10,537 meters at Yauricocha. The drilling included the following:

Exploration Drilling:

  • Copper Porphyry Mineralization (Central Mine Zone Level 720): 2 holes totaling 1,341 meters were drilled to continue to test the priority anomaly located in the monzonite intrusive zone, where a copper molybdenum mineralized porphyry was discovered earlier in the year; drill results continue to display the presence of a copper molybdenum porphyry orebody, where we have observed typical alterations, as well as copper mineralization disseminated in the encased rock, as veinlets with quartz and copper are present with molybdenum;
  • Cuye Orebody (Level 1070 Central Mine Zone): 1 hole totaling 210 meters to explore the continuity of mineralization of the orebody at depth; the hole confirmed the continuity of this mineralized orebody at depth;
  • Catas Orebody (Level 1070 Central Mine Zone) – 1 hole totaling 681 meters confirmed the continuity of the copper mineralization at depth;
  • Contacto Occidental Orebody (Level 1070 Central Mine Zone): 1 hole totaling 86 meters confirmed the continuity of the mineralization at depth of this “cuerpo chico” “small orebody”;
  • Escondida Norte (Level 870 Cachi Cachi): 4 holes totaling 1,745 meters with the objective of exploring and defining the fresh sulphide zones, as areas previously explored in this area have intercepted oxide zones with silver and lead mineralization; these holes drilled intercepted mineralized structures of polymetallic sulphide zones;
  • Cachi Cachi Norte (Level 720 Cachi Cachi): 2 holes totaling 681 meters with the objective of exploring the northern part of the mineralized ore bodies within the Cachi Cachi Mine that did not encounter any mineralization of ore grade material.

Definition Drilling:

  • Antacaca Sur (Level 920): 17 holes totaling 2,186 meters with the objective of defining more certainty on the orebody between the 970 level sublevel and the future sublevel 8 meters above the 1020 level;
  • Esperanza (Level 970): 14 holes totaling 1,770 meters which confirmed the continuity of mineralization of the orebody; holes were executed between the sublevel development level 8 meters above the 1020 level and the 1020 level;
  • Angelita (Level 870 Cachi Cachi): 11 holes totaling 1,577 meters which represents the orebody on the 870 sublevel between an area 16 meters and 8 meters above the 870 level;
  • Yoselin (920 Level Cachi Cachi Mine): 5 holes totaling 260 meters which confirmed the orebody and the extension of the orebody to 1070 level. These drill holes provided more geological information to help plan potential mining of the orebody. Once the drift reaches the 1070 level the remainder of orebody below will be drilled off from the 1070 level. Initial highlights of the average grades encountered in this “cuerpo chico” or “small orebody” included 1.2 Oz Ag, 4.8% Pb, 0.09% Cu, 8.5% Zn. Further assay results are pending but we will continue to drill the Yoselin zone.



  • At Bolívar during Q4 2018, 6,258 meters were drilled from surface as well as diamond drilling within the mine. 2,183 meters were drilled within the mine in the El Gallo zone. There was also 3,865 meters drilled at the Bolivar West extension 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 was also 210 meters drilled at La Campana, which is a new exploration target where we are exploring the possibility of finding a skarn orebody with copper and zinc;


  • During Q4 2018 the Company drilled 1,781 meters to support the development of the Santa Rosa de Lima vein in Promontorio to further verify the size and continuity of the orezone. 2,497 meters of surface diamond drilling was performed to explore the depth of the mineralized structure of San Nicolas in the area of the San Juan Mine.
