The Borborema mine produced 2,577 GEOs following its first gold pour. The company said Borborema remains on track to declare commercial production by the end of the third quarter.

Separately, Aura said it signed a subscription agreement with Altamira, under which it acquired 6 million units of Altamira in a non-brokered private placement at $0.10 per unit for a total of $600,000.

Each unit consists of one common share and one-half of one common share purchase warrant exercisable to acquire one Altamira share at an exercise price of $0.15 apiece until June 30, 2027.

Before the agreement, Aura held 24 million shares and 24 million warrants, representing about 20.3% of the issued and outstanding shares on a fully diluted basis.

Upon closing of the private placement, Aura holds 30 million shares and 27 million warrants, representing approximately 19.5% of the shares on a fully diluted basis.

Aura said it acquired the units as an investment given the exploration potential of Altamira.
