• Copper equivalent pounds production increased 30% to 20.1 million pounds.
• Zinc equivalent pounds production increased 52% to 54.6 million pounds.
• The Yauricocha Mine and the Company are trending towards copper as our main product as a percentage of revenue and as a percentage of Net Smelter Royalty, as such we are also reporting copper figures in addition to zinc in this press release.
• $30.5 million of cash and cash equivalents as at March 31, 2020.

The Yauricocha Mine achieved 22% higher throughput in Q1 2020 compared to Q1 2019, despite 15 days lost production realized in March due to the COVID-19 related state of emergency announced by the Peruvian government. Continuing its strong operational performance during Q1 2020, the mine realized a 30% increase in copper equivalent production or a 52% increase in zinc equivalent metal production compared to Q1 2019. The revenues and adjusted EBITDA generated during Q1 2020 allowed the Company to fund its capital expenditure programs, despite a challenging metal price environment. Cash costs per copper equivalent payable pound decreased 7% whereas cash costs per zinc equivalent pound decreased by 20%. AISC per copper equivalent pound increased by 13% whereas AISC per zinc equivalent pound decreased by 4% as compared Q1 2019.

Igor Gonzales, President and CEO of Sierra Metals commented, “Corona had a strong first quarter with strong throughput, an increase in the production of all metals, and a significant increase in copper and zinc equivalent metal production. This occurred despite reductions in throughput and staffing related to the state of emergency declared at the end of March due to the COVID-19 pandemic. During the quarter, the Mine had been running at higher throughput levels building up processed tonnage as a buffer against any potential interruptions. Additionally, we also had a stockpile of ore, which enabled us to continue processing close to capacity at the mill. With that, we reported healthy revenue and adjusted EBITDA for the first quarter despite facing much lower metal prices and much higher zinc treatment and refining charges. Yauricocha continues to be a strong performing asset for the Company, and we continue to reap the benefit of prudent investments and operational improvement programs at the Mine.

Looking ahead, we face several uncertainties due to the COVID-19 pandemic, including implications to production from the work stoppages and the effect of lower metals prices. We maintain an essential services crew at Yauricocha and expect to ramp-up back to normal levels as quickly and efficiently as possible once the suspension is lifted in Peru. I want to remind shareholders that we do have the flexibility at Yauricocha to run the operations at higher throughput levels, which will help us to recover some of the lost production during the remainder of the year. Additionally, we continue to be optimistic that we will still receive the required permits to increase output at Yauricocha to the 3,600 tpd level this year, even though permitting in Peru was placed on hold by the government during the state of emergency.”

He concluded, “Corona continues to have a strong balance sheet and liquidity. We have reduced and deferred capital expenditures to ensure we emerge from the pandemic in a strong position. Once a more normal situation returns, and metal prices improve, we are still poised for strong future production and cash flow growth, and we will continue to make prudent, strategic investments which will benefit all shareholders.”

Corona’s Financial Highlights for the Three Months Ended March 31, 2020

• Revenues of $33.7 million for Q1 2020 compared to $35.3 million in Q1 2019. Revenues were 5% lower as the impact of higher treatment and refining costs and a decline in base metal prices was offset by higher metal sales, attributable to 22% higher throughput and higher grades as compared to Q1 2019. Copper equivalent payable pounds for Q1 2020 increased by 24%, whereas Zinc equivalent payable pounds for Q1 2020 increased by 46% as compared to the same quarter of 2019.
• Cash cost per copper equivalent pound sold was $1.17 for Q1 2020 compared to $1.26 for Q1 2019. Cash cost per zinc equivalent pound sold was $0.43 for Q1 2020 compared to $0.54 for Q1 2019 at the Yauricocha Mine.
• All-in sustaining cost (“AISC”) per copper equivalent pound sold was $2.24 for Q1 2020 compared to $1.97 for Q1 2019. Cash cost per zinc equivalent pound sold was $0.82 for Q1 2020 compared to $0.85 for Q1 2019. AISC per copper equivalent pound for Q1 2020 increased as the 24% increase in copper equivalent could not offset the higher treatment and refining charges and higher sustaining capital costs. AISC per zinc equivalent payable pound for Q1 2020 decreased as the impact of the increase in treatment and refining charges and higher sustaining capital costs was partially offset by a 46% increase in zinc equivalent pounds.
• Adjusted EBITDA of $ 9.8 million for Q1 2020 as compared to adjusted EBITDA of $ 13.7 million for the same quarter of 2019, lower mainly due to the lower net income.
• Operating cash flows before movements in working capital of $10.1 million for Q1 2020, compared to US$13.2 million for Q1 2019. The decrease in operating cash flows before movements in working capital for Q1 2020 was primarily due to the decrease in revenues, discussed previously.
• Cash and cash equivalents of $30.5 million as at March 31, 2020, compared to $35.0 million as at December 31, 2019. Cash and cash equivalents decreased as cash used in investing activities of $7.8 million exceeded operating cash flows after working capital adjustments and taxes of $3.7 million.
• Net income of $2.1 million, or $0.057 per share for Q1 2020 compared to net income of $8.0 million, or $0.22 per share for Q1 2019.
