Nature and continuance of operations and going concern	1. Nature and continuance of operations and going concern Bunker Hill Mining Corp. (the “Company”) was incorporated under the laws of the state of Nevada, U.S.A on February 20, 2007 under the name Lincoln Mining Corp. Pursuant to a Certificate of Amendment dated February 11, 2010, the Company changed its name to Liberty Silver Corp., and on September 29, 2017 the Company changed its name to Bunker Hill Mining Corp. The Company’s registered office is located at 1802 N. Carson Street, Suite 212, Carson City Nevada 89701, and its head office is located at 82 Richmond Street East, Toronto, Ontario, Canada, M5C 1P1. As of the date of this Form 10-KT, the Company had one subsidiary, Silver Valley Metals Corp. (formerly American Zinc Corp.), an Idaho corporation created to facilitate the work being conducted at the Bunker Hill Mine in Idaho. The Company was incorporated for the purpose of engaging in mineral exploration activities. It continues to work at developing its project with a view towards putting it into production. These consolidated financial statements have been prepared on a going concern basis. The Company has incurred losses since inception resulting in an accumulated deficit of $66,088,873 and further losses are anticipated in the development of its business. The Company does not have sufficient working capital needed to meet its current fiscal obligations and commitments. In order to continue to meet its fiscal obligations in the current fiscal year and beyond, the Company must seek additional financing. This raises substantial doubt about the Company’s ability to continue as a going concern. Its ability to continue as a going concern is dependent upon the ability of the Company to generate profitable operations in the future and/or to obtain the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management is considering various financing alternatives including, but not limited to, raising capital through the capital markets and debt financing. These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts of and classification of liabilities that might be necessary in the event the Company cannot continue in existence. The ability of the Company to emerge from the exploration stage is dependent upon, among other things, obtaining additional financing to continue operations, explore and develop the mineral properties and the discovery, development, and sale of reserves. These financial statements of the Company for the six months ended December 31, 2020 were approved and authorized for issue by the Board of Directors of the Company on March 30, 2021. The Company’s operations could be significantly adversely affected by the effects of a widespread global outbreak of epidemics, pandemics, or other health crises, including the recent outbreak of respiratory illness caused by the novel coronavirus (“COVID-19”). The Company cannot accurately predict the impact COVID-19 will have on its operations and the ability of others to meet their obligations with the Company, including uncertainties relating to the ultimate geographic spread of the virus, the severity of the disease, the duration of the outbreak, and the length of travel and quarantine restrictions imposed by governments of affected countries. In addition, a significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations.
