Business Summary and Project Updates

Rodeo Project Developed for 2021 Production

Golden received final environmental permits in November 2020, began mining activities in December 2020, and ultimately trucked the first loads of material to its nearby Velarde?a Properties for processing in early January 2021. The Company announced Rodeo's first gold pour on January 31, 2021. The project was brought online ahead of time and on budget, and Golden is currently ramping up operations to the intended processing rate of 450 tonnes per day by the end of the first quarter 2021.

As part of the Company's long-term strategic plan, during 2020 the Company completed multiple activities in advance of bringing Rodeo into production, which was timed to occur shortly after Hecla vacated the oxide plant. Golden issued an independently-prepared Preliminary Economic Assessment ("PEA") for the Rodeo project in April 2020 and conducted an infill resource definition drilling program during the second quarter. That drill program provided sample material for metallurgical/geotechnical testing and gave the planning team greater detail on Rodeo's gold mineralization.

Oxide Mill Lease Concludes

The multi-year lease of the Company's oxide mill to Hecla concluded per the terms of the agreement on November 30, 2020. During 2020, Hecla processed approximately 120,000 tonnes of material through Golden's oxide plant, resulting in revenue to Golden of $5.6 million, which included $2.0 million for reimbursable costs related to the services Golden provided under the terms of the lease. The $2.0 million of reimbursable costs are also reported as plant lease costs, resulting in a net operating margin of $3.6 million for the full year.

Velarde?a Properties

The Company announced positive results from an updated PEA for the Velarde?a Properties in April 2020. The PEA was prepared to incorporate new and updated elements of the project database, mine plan and processing plan, most notably the inclusion of bio-oxidation treatment of gold concentrates. Golden Minerals believes this technology is key to unlocking successful and sustainable value from production at Velarde?a. Indeed, 2019 BIOX testing of Velarde?a material achieved payable gold recoveries of 92%, compared to sub-30% payable gold recoveries realized when Golden last operated Velarde?a in 2015.

During 2021, the Company will continue to optimize the mine plan and processing details in preparation for future test-mining and processing, both in advance of establishing a definitive schedule for restarting commercial production. Internal technical and economic evaluations are in progress regarding potentially accelerating the production restart to late 2021 or early 2022.

El Quevar

In April 2020, the Company entered into an Earn-In Agreement with Barrick, under which Barrick has acquired an option to earn a 70% interest in the El Quevar project (Salta Province, Argentina) over a period of eight years. In order to earn the 70% interest, Barrick must complete certain defined work activities and deliver a pre-feasibility study to Golden as stipulated in the Earn-In Agreement. During the earn-in period, Barrick will fund the holding costs of the property and reimburse Golden Minerals for expenses related to maintaining the exploration camp. Due to the COVID-19 pandemic and related legal restrictions on mining exploration in Salta, Argentina, Barrick declared a force majeure event under the Earn-In Agreement. As a result, the earn-in period and other deadlines in the Earn-in Agreement were extended by 119 days. The force majeure event is no longer in effect and Barrick has begun activities at the site.

Yoquivo

Golden Minerals completed a phase one drill program in December 2020 at its Yoquivo gold-silver project (Chihuahua, Mexico), drilling 15 holes totaling approximately 3,400 meters exploring the four known vein systems exposed on the property. The program identified multiple veins with potentially economic gold-silver grades within the Company's district-scale holdings, including most notably a newly discovered vein without previous historic mining. The Company intends to follow with a second phase drill program in 2021.

Santa Maria

In December 2020, the Company entered into a definitive Option Agreement to sell its option in the Santa Maria silver-gold project (Chihuahua, Mexico) to Fabled Silver Gold Corp. ("Fabled"). The period to exercise the option expires on December 4, 2022. As consideration for the option, Fabled paid $0.5 million and issued 1.0 million shares of its common stock to the Company. In addition, Fabled will pay $1.5 million in cash to the Company on the one year anniversary of the Option Agreement, $2.0 million in cash to the Company on the two year anniversary of the Option Agreement, and upon exercise of the Option will grant the Company a 1% net smelter return royalty on certain Santa Maria concessions.

2020 Financial Results

The Company reported revenue of $5.6 million and a net operating margin of $3.6 million in 2020, compared to $7.7 million and $5.3 million in 2019, respectively. Both are wholly related to the lease of the Company's Velarde?a oxide plant to Hecla. The 2020 figures reflect (a) a reduction in the per tonne processing fees during the first six months of 2020 related to an amendment in lease terms; (b) termination of the lease agreement one month early on November 30, 2020, and (c) a temporary shutdown in operations in April-May 2020 due to COVID-19 restrictions mandated by the Mexican government.

Total expenses of $14.4 million in 2020 were $1.6 million higher than the $12.8 million in total expenses recorded in 2019. Exploration expenses totaled $5.0 million in 2020 vs. $4.1 million in 2019, with the increase related primarily to work conducted at the Rodeo project in preparation for the start of mining and processing activities. Velarde?a care and maintenance expenses were $1.2 million compared to $1.8 million in 2019. El Quevar project expense was $0.6 million in 2020 vs. $2.0 million in 2019, with the lower 2020 figure reflecting reimbursement of certain expenses by Barrick per the terms of the Earn-In Agreement, as well as the 2019 figure including costs associated with a drilling program. Administrative expenses were $3.7 million in 2020 compared to $3.6 million in 2019. The Company recorded only a nominal amount of other operating income (net) in 2020, compared to $3.2 million in 2019. The 2019 figure reflected the sale of two of the Company's Mexican exploration properties and the sale of surplus equipment. The Company reported a net loss of $9.1 million or ($.07) per share in 2020 compared to a net loss of $5.4 million or ($.05) per share in 2019.
