Rimouski, April 10, 2012 – Puma Exploration (PUM-TSXV) is pleased to annnouce that the summer

exploration program at Nicholas-Denys has started and is ahead of schedule due to unexpected warmer

spring weather conditions. Line cutting and wood cutting are completed and drilling site preparation is under

way and the drill rig will be on site by the end of the week.

A drilling program will start with a first phase of 1000 meters to test the new targets at the Haché lens. The

silver and gold oreshoot will be tested at depth in accordance with the new discovery model developed

during the 2011 summer program as well as the surface lateral extensions towards the Henry East Lens.

Previous drilling at Haché intercepted the gold and silver oreshoot down to a depth of 75 meters with grades

of 477 g/t Ag and 1.9 g/t Au over 6.0 meters, 720 g/t Ag and 3.8 g/t Au over 8.4 meters and 265 g/t Ag and

1.0 g/t Au over 11.9 meters. Drilling will then be done on the Dante and the Henry East Lenses following the

major stripping program.

Line cutting is complete from the Shaft lens to the Great Northern lens for a total strike length of 6.0 km. A

total of 100 km of lines cover the 3 main structures hosting, so far, 16 silver and gold showings and deposits.

A magnetic ground survey is underway over this new grid and should be completed shortly. This survey will

be useful to identify new surface mineralization as well as the tranverse faults and structures which have a

major role in the gold and silver enrichments at Nicholas-Denys.

Wood cutting has also been completed in the Dante Lens area (see press release 18/01/2012) to extend the

stripping area for an additional 200 meters to the east and to the west and also over the Henry East Lens (see

press release 06/02/2012) for an area of 650 meters long by 100 meters wide. A major stripping program will

be completed on these areas to identify, locate and sample the thicker portion of the mineralized areas and

then, the main gold and silver oreshoots will be drilled.
