McEwen Mining: Q3 2021 Results






McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) today reported its third quarter results for the period ended September 30th, 2021.

  • We continue to execute our turnaround strategy and have made significant progress both from an operational and a financial perspective (see Tables 1-3 below). We expect this trend to continue with the ongoing production ramp-up from the Froome deposit at the Fox Complex.
  • Our operations delivered production results in line with our expectations, and we are on track to meet our 2021 production guidance of 141,000 to 160,400 GEOs.
  • Cash and liquid assets(1) and working capital at September 30th, 2021 were $72.7 million(2) and positive $45.8 million, respectively, including $40 million of cash raised by our McEwen Copper subsidiary to advance the Los Azules project.
  • Continued to aggressively invest $6.2 million in exploration and $4 million in advanced projects, primarily focused on the Fox Complex.
  • These investments in our future growth and profitability accounted for a large part of our reported net loss of $17.4 million, or ($0.04) per share, compared to a net loss of $9.8 million, or ($0.02) per share in Q3 2020.
  • Commercial production at the Froome deposit was reached on September 19th. Froome is the newest production area at the Fox Complex and has several advantages compared to Black Fox mine, such as a straighter, shorter, and more efficient underground haulage route, and wider more consistent mineralization that is amenable to lower-cost bulk mining methods.
  • Results of the Fox Complex Expansion PEA are expected by the end of Q4 2021. The study will incorporate the 2021 exploration and resource definition drilling results and will highlight the exciting development plans for the Grey Fox and Stock deposits.
  • Our quarterly webcast will take place on Thursday, November 4th at 2 pm EDT. Please see the details further below.

Operations Update


Gold Bar Mine, USA (100% Interest)


Gold Bar production for Q3 and 9M was 82% and 54% better, respectively, compared to Q3 and 9M 2020. While cash costs(2) and all-in sustaining costs(2) for the 9M period dropped by 10% and 21%, respectively, compared to 9M 2020.


12,400 GEOs were produced in Q3 at total cash costs and AISC of $1,553 and $1,618 per GEO sold, respectively. This compares to 6,800 GEOs in Q3 2020 at total cash costs and AISC of $1,585 and $1,769 per GEO, respectively. AISC was positively impacted by less capital investment in processing equipment in 2021 versus 2020.


Exploration is focusing on near-mine targets and further defining oxide resources on the neighboring Tonkin property that could potentially be processed at Gold Bar. During the quarter, we incurred exploration expenses of $1 million. Encouraging results at the Tonkin Rooster deposit included drill intercepts up to 1.0 g/t gold over 57.9 m and a cyanide solubility(3) of 74% and 3.2 g/t gold over 38.1 m (including 14.7 g/t over 6.1 m) with an 11% cyanide solubility that occur within a complex structural framework. An ongoing program of remapping, relogging historic drill holes and producing an updated geologic model by year-end will establish a basis for continued exploration at the Tonkin Property in 2022.


Fox Complex, Canada (100% Interest)


Fox production for Q3 and 9M was 43% and 26% better, respectively, compared to Q3 and 9M 2020. Cash costs and AISC for the 9M period both dropped by 23%, compared 9M 2020.


8,300 GEOs were produced in Q3 at total cash costs and AISC of $1,154 and $1,423 per GEO sold, respectively. This compares to 5,800 GEOs in Q3 2020 at total cash costs and AISC of $1,581 and $1,644 per GEO, respectively. The increase in production and the corresponding decrease in costs were attributed to improved efficiencies realized from production at the Froome deposit. In September, commercial production was achieved at Froome, three months ahead of schedule. Mining from Froome is expected to bridge production while the Grey Fox and Stock projects will be advanced in the production pipeline.


At the Stock property, we see the opportunity to further expand the Stock West footprint beyond the grade-thickness contours shown below (see Figure 1). Of particular interest is hole S21-202, which returned 4.4 g/t gold over 21.0 m estimated true width, 200 m above hole S19-95, which returned 27.2 g/t gold over 7.0 m. These holes are located at the projected intersection of the Stock West shallow eastern plunge and the historically steep Stock Mine plunge, and they command further drilling in 2022.

We remain focused on our principal exploration goal of cost-effectively discovering and extending gold deposits adjacent to our existing operations to contribute to near-term gold production growth. During the quarter, we incurred exploration expenses of $4.2 million in relation to this program.

The Preliminary Economic Assessment (PEA) for the Fox Complex expansion will be released later this quarter. It is based on the Grey Fox, Froome, Stock, and Fuller resources, which are envisioned to be mined and then processed at an upgraded centralized mill at Stock. The objective of the PEA is to outline a low-cost, near-term business case that increases production and mine life for the Fox Complex.


San José Mine, Argentina (49% Interest)


San José attributable production(4) for Q3 and 9M was 36% and 43% better, respectively, compared to Q3 and 9M 2020. While cash costs and AISC for the 9M period dropped by 11% and 6%, respectively, compared 9M 2020.


Attributable production was 10,800 gold ounces and 790,000 silver ounces, for a total of 21,600 GEOs(3). For Q3, total cash costs and AISC were $1,100 and $1,466 per GEO sold, respectively. This compares to 15,900 GEOs in Q3 2020 at total cash costs and AISC of $1,269 and $1,538 per GEO, respectively.


In 2021, we have received $10 million in dividends from our interest in San José.


Exploration drilling in the mine area at San José returned encouraging results including: 6.3 m of 44.4 g/t gold in the Betania vein, 1.9 m of 14.5 g/t gold and 342 g/t silver in the Jimena vein, and 4.3 m of 14.9 g/t gold and 1,381 g/t silver in the Amelia vein.


McEwen Copper


Activity at McEwen Copper’s Los Azules project is moving ahead quickly. The exploration road has been reopened, three work camp sites have been established, an expanded local labor force and preparations are underway for starting a 10-drill, 174,000-foot (53,000 m) drilling program. Drilling will focus on conversion of Inferred mineral resources to the Indicated category, as well as deeper exploration targets, where drilling ended in strong copper mineralization. Drills are expected to turn towards the end of November and continue through the end of Q2 2022.


Construction of the new access road for providing the necessary year-round access to the project is advancing as planned. As part of our ongoing involvement with local communities and businesses, local contractors are being sourced for the construction.


The contract for delivery of a pre-feasibility study (PFS) is at the tender stage and work is expected to begin in Q4. Whittle Consulting has been engaged to assist in identifying opportunities to improve the project that will be investigated during the PFS preparation.
