MISTANGO COMPLETES INFILL DRILLING PROGRAM AIMED AT UPGRADING EXISTING RESOURCE

Kirkland Lake, Ontario, March 21, 2013   Mistango River Resources Inc. (MIS : CNSX) (GLRAF : OTC) today announced the latest results of the last two deep  down plunge extension holes drilled on the Omega Deposit and five infill holes in the potential open pit area. The five infill holes are part of the already completed ( pending partial assays) 14 DDH, planned by AMC Mining Consultants in order to upgrade the existing potential open pit resource of 3.8 million tonnes, containing 306,100 Oz Au at 2.5 g/t Au, into the indicated category.  The total inferred resource of the potential open pit and the down dip extension below contains 5 million tonnes, totaling 472,100 ounces of gold.

Drilling Highlights

OM-13-107    3.495 g/t gold over 32 metres (including 2 metres of 17.225 g/t gold)

OM-13-109    1.763 g/t gold over 57 metres (including 19 metres of 2.656 g/t gold and 5 m of 3.522 g/t gold)

Omega Property composite table as of March 21, 2013

*previously reported: all holes are uncut and over core length; core length is estimated 50-90% of true width;  1 g/t Au multiplied by 0.0291666 equals troy ounces per short ton (to convert from metres to feet multiply by 3.2808). NSV: no significant values. VG: visible gold

Robert J.  Kasner President and CEO, commented, ?We are pleased to announce that a new drill rig has been able to penetrate through various drifts and stopes and recover core, where previous attempts have failed. It is believed that this new drilling should increase the size of the resource and upgrade the existing inferred resource into indicated in the potential open pit area?.

QA/QC was followed in sampling the core. The core is sawed in half for sampling. Standards, blanks and duplicates were inserted into the stream of core samples every 20 metres. The core was assayed at ALS Minerals Canada LTD in Sudbury, ON using 30 gram samples. The core samples were analyzed using the fire assay method and AA finish for results up to 10 g/t Au. For samples containing more than 10 g/t Au gravimetric finish was used.
