THIRD QUARTER 2021 HIGHLIGHTS

Generated revenues of $124.6 million, representing a 1% decrease due to the decision to withhold 1.4 million ounces of silver in inventory in an effort to maximize future profits. Had the Company sold these ounces at the end of the quarter it would have generated approximately $33.2 million in additional revenue using the quarterly average realized price of $23.10 per ounce

Cash costs increased to $14.09 per AgEq ounce due to the addition of Jerritt Canyon

All-in sustaining costs ('AISC') increased to $19.93 per AgEq ounce primarily due to an increase in sustaining capital costs related to the $12.3 million Tailings Storage Facility 2 ('TSF2') lift project at Jerritt Canyon

Mine operating earnings of $3.5 million during the quarter, compared to earnings of $48.0 million in Q3 2020, the decrease in earnings was primarily attributed to lower silver ounces sold due to the holdback of 1.4 million ounces of silver along with higher costs attributed to the first full quarter of operations at Jerritt Canyon

Net earnings of ($18.4) million attributed to the reduction in revenue as a result of withholding 1.4 million ounces of silver from sales at quarter end

Adjusted EPS of ($0.07) after excluding non-cash and non-recurring items

Cash flow per share of $0.09 (non-GAAP)

Cash and cash equivalents at September 30, 2021 were $192.8 million with strong working capital of $262.5 million

Declared a third quarter cash dividend payment of $0.0049 per common share for shareholders of record as of the close of business on November 17, 2021 which will be distributed on or about November 30, 2021

'Our decision to inventory a significant amount of silver during the quarter obviously impacted our third quarter financial results but those additional revenues and cash flows are expected to be realized in the coming quarters as prices improve,' stated Keith Neumeyer, President and CEO. 'During the quarter, we also invested in two significant capital projects at Jerritt Canyon which temporarily increased our all-in sustaining costs at the site. With the majority of these investments now complete, we expect a reduction in costs starting in the fourth quarter driven by higher production, reduced capital costs and continued improvements in operating efficiencies. At San Dimas, AISC costs decreased by 19% to $11.58 per ounce due to higher production and higher consumption rates of low-cost energy from our hydro dam when compared to diesel or grid power. At Santa Elena, the mill is preparing to begin test batching low-grade stockpiles from the Ermitano deposit which is expected to further drive down costs and increase overall production. Finally, the Company declared its third quarter dividend which was also impacted by the lower quarterly revenues due to the withholding of the 1.4 million unsold ounces of silver, however, the upcoming future quarter dividends are expected to increase as this large inventory is divested.'
