Mantra Mining Inc. (the "Company") (TSX VENTURE:MAN). The Company is pleased to
announce that it has completed the acquisition of 100% interest in and to
approximately 5,428 Ha (hectares) of mineral claims (the "Gnome Claims") from
Charles James Greig subject to a 1% NSR Royalty pursuant to a purchase agreement
previously announced in a news release dated March 12, 2009.


The Gnome Claims are located in the same belt NE of Williston Lake (the Kechika
Trough) as the well known Cirque and Akie Sedex Zn-Pb-Ag properties in British
Columbia, Canada. The Project is located immediately adjacent and contiguously
south of the Elf mineral claims held by Teck Resources and Korea Zinc. The Elf
mineral claims of Teck Resources are located contiguously south of the Akie
mineral claims held by Mantle Resources Inc., which claims in turn are located
south of the Cirque deposit/claims of Teck Resources and Korea Zinc.


The consideration paid by the Company for the acquisition of the Gnome Claims
consisted of $3,000 in cash and 15,000 common shares of the Company at a deemed
price of $0.50 per share. The Company has the right to purchase the 1% NSR
royalty retained by Mr. Greig for $2,000,000 up to the period ending on the 10th
anniversary of the closing date.
