On August 21, 2018, Avino Silver & Gold Mines, Ltd. (the “Company”) filed a registration statement on Form F-3 (Registration No. 333-226963) (“Form F-3”) with the Securities and Exchange Commission (the “SEC”) to register $25,000,000 of the Company’s common shares, warrants to purchase common shares, debt securities and units consisting of common shares, warrants or debt securities or any combination of these securities in one or more transactions. The Form F-3 was declared effective by the SEC on September 5, 2018.

In connection with the Form F-3, the Company filed a final prospectus supplement with the SEC on September 21, 2018 for the offer of 6,239,867 of common shares and warrants to purchase up to 6,239,867 common shares and the common shares that are issuable from time to time upon exercise of the warrants (the “Prospectus”).

This Form 6-K is being filed for the purpose of clarifying the aggregate market value of the common shares of the Company held by non-affiliates on the cover page of the Prospectus.

The aggregate market value on the cover page of the Prospectus should be clarified to reflect that:

“Based on a closing price of $1.19 per share on July 23, 2018, a date within sixty days of the date of this prospectus supplement, the aggregate market value of our outstanding common shares held by non-affiliates was approximately $63,714,749 based on 56,206,346 common shares outstanding on September 21, 2018, of which 53,541,806 common shares were held by non-affiliates.”
