Three further grab samples from the Norwalk Adit entrance returned 110 ppb to up to 200 ppb Au.

Seven grab samples were taken from the Gananoque Adit entrance and returned 20 ppb and up to 1.45 g/Mt Au.

Five grab samples were taken from an historic trench on the south west corner of the Norwalk Property and all were gold-bearing

and returned assays from 10 ppb up to 120 ppb Au.

Gold mineralization at Norwalk is hosted by altered diorite, gossan and quartz. Gold-bearing composite sample 42815

demonstrates that gold mineralization may occur over significant widths.

Rock samples were submitted to Swastika Laboratories Ltd. for Gold fire assay. Swastika Laboratories Ltd. is accredited

by Canadian Association for Laboratory Accreditation Inc. (CALA) and meets the requirements of ISO/IEC 17025:2005 for Gold

by Fire Assay.

Paul Antoniazzi, President of RT Minerals Corp., states,

"The Company is very encouraged with

the

widespread

grade gold

assays

obtained

from the

recent

limited

surface sampling program. In my experience, it is

significant

to have so many gold

bearing samples

from initial sampling of

several different areas of

the ~

1,000 acre property.

G

eophysical targets associated

with this mineralization will be

prioriti

z

ed and

drilled immediately."

The Company is currently completing a 31 kilometre surface geophysical surveys covering parts of the Norwalk gold property.

Upon completion of magnetic and IP (induced polarization) surveys, a drill program will be initiated to test targets. The drill

program is expected to commence in the next 2 to 3 weeks. Details of the drill program will be announced when drill mobilization

occurs.
