The Company wishes to advise its shareholders that the Mexican government had decreed an extension of the suspension of all non-essential activities until May 30, 2020. However, this extension does not apply to municipalities that present low or no known cases or transmission of the SARS-CoV2 virus, subject to criteria to be defined by the Secretariat of Health. As Ridgestone’s Rebeico project is located in a municipality with low or no transmission of the SARS-CoV2 virus, the Company’s activities and those of its service providers have now re-commenced.

Core samples from the first three drill holes at the New Year Zone, which encountered abundant sulphides, have been sent to ALS Chemex in Hermosillo for assaying with results anticipated to be released in the coming weeks when available.

The Company also announces that its common shares are now listed on the Frankfurt Stock Exchange ("FRA") and are under the trading symbol 4U5 with ISIN: CA76611L1040 and WKN: A2P3SM. The listing of the Company's shares on the Frankfurt Stock Exchange will broaden the corporation's shareholder base in Europe and increase trading activity in its shares, while at the same time facilitating investment in the company by the European investing community. The Frankfurt Stock Exchange is one of the world's largest organized exchange trading market in terms of turnover and dealing in securities. The Company's shares continue to be listed on the TSX Venture Exchange under the symbol RMI and on the US OTCQB under RIGMF.
