As a result of the COVID-19 outbreak, and the social distancing measures enacted to slow its spread, energy prices decreased in March 2020. The full impact of the COVID-19 outbreak continues to evolve as of the date of the report. As such, it is uncertain as the full magnitude that the pandemic will have on the Company's financial condition and liquidity. Management is actively monitoring the global situation and its potential impact. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effect of the COVID-19 outbreak on management's assumptions for fiscal year 2021. Although the Company cannot estimate the length or the gravity of the impact of the COVID-19 outbreak at this time, the longer the pandemic continues, the greater the likelihood that it will have an adverse effect on the Company's financial position in fiscal year 2021.

NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY

1. NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY:

I-Minerals Inc. (the “Company”) was incorporated under the laws of British Columbia, Canada, in 1984. The Company is listed for trading on the TSX Venture Exchange under the symbol “IMA” and the OTCQB marketplace under the symbol “IMAHF”.

The Company’s principal business is the development of the Helmer-Bovill industrial mineral property (“the Property”) located in Latah County, Idaho. Since inception, the Company has been in the exploration and evaluation stage but moved into the development stage in fiscal 2018. In fiscal 2019, the Company reverted back to the evaluation stage as management determined that the Feasibility Study on the property should be considered non-current. The Helmer-Bovill property is comprised of eleven mineral leases that host potentially economic deposits of feldspar, quartz and kaolinitic clays, primarily kaolinite and halloysite.

Basis of Presentation and Liquidity

The accompanying consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its obligations and continue its operations for the next year. Realization values may be substantially different from carrying values as shown and these financial statements do not give effect to adjustments that would be necessary to the carrying values and classification of assets and liabilities should the Company be unable to continue as a going concern. At April 30, 2020, the Company had not yet achieved profitable operations, had an accumulated deficit of $48,127,316 since inception and expects to incur further losses in the development of its business, all of which casts substantial doubt upon the Company’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business.

The Company’s ability to continue as a going concern is dependent upon its ability to obtain the necessary financing to develop the Property and to meet its obligations and repay its liabilities arising from normal business operations when they come due. Although the Company has been successful in the past in obtaining financing, there is no assurance that it will be able to obtain adequate financing in the future or that such financing will be on terms advantageous to the Company.
