AURA MINERALS ANNOUNCES FILING OF EARLY WARNING REPORT REGARDING ALTAMIRA GOLD CORP.

Aura Minerals Inc. has entered into a subscription agreement with Altamira Gold Corp., pursuant to which it acquired, in a non-brokered private placement, six million units of the issuer at a price of 10 cents per unit for an aggregate purchase price of $600,000. Each unit consists of one common share and one-half of one common share purchase warrant of the issuer. Each warrant is exercisable to acquire one share of the issuer at an exercise price of 15 cents per share until June 30, 2027.

Prior to entering into the subscription agreement, Aura held 24 million shares and 24 million warrants, representing approximately 11.3 per cent of the issued and outstanding shares on a non-diluted basis, and approximately 20.3 per cent of the issued and outstanding shares on a fully diluted basis. Immediately upon the closing of the private placement, Aura holds 30 million shares and 27 million warrants, representing approximately 11.3 per cent of the issued and outstanding shares on a non-diluted basis, and approximately 19.5 per cent of the issued and outstanding shares on a fully diluted basis. Aura acquired the units directly from the issuer in the private placement, and not through the facilities of any stock exchange or other marketplace.

Aura acquired the units for investment purposes given the exploration potential of Altamira. Aura may, from time to time and depending on the market and other conditions, acquire additional securities of the issuer, dispose of some or all of the existing or additional securities it holds or will hold, or may continue to hold its current position, depending on market conditions, reformulation of plans and/or relevant factors.
