Puma Exploration Inc.: Conclusive Metallurgical Test on the Hache Lens, New Brunswick

RIMOUSKI, QUEBEC--(Marketwire - Nov. 15, 2007) - Puma Exploration (TSX VENTURE:PUM) has just received the results of the metallurgical test carried out on mineralization from the Hache lens on the Nicholas-Denys property in New Brunswick. The metallurgical testing was designed to estimate the recovery rates for valuable metals in the ore, so as to assess the potential earnings after preliminary concentration, i.e., ex mill.

The test was conducted on the mineralization intersected during the most recent drilling on the Hache lens. A composite 30-kg sample was made up from four different holes covering the whole lens. A total of 25 metres of mineralized core were crushed and mixed together to produce a single homogeneous composite sample representative of the mineralization in the Hache lens. The sample was processed and analyzed at the SGS Lakefield Research laboratory in Ontario. Initial analysis of the 30-kg composite sample gave 460 g/t Ag, 2.2 g/t Au, 6.0% Zn, and 3.7% Pb (Press Release: 2007-07-10).

The metallurgical testing produced two separate concentrates: a lead concentrate and a zinc concentrate. The primary coarse grinding of the ore was done to 77 microns. Regrinding to 20 microns for the lead concentrate and 30 microns for the zinc concentrate was sufficient to achieve high recoveries.

Cleaning tests of the two concentrates enabled recovery of 84% of the zinc, 90% of the lead, 84% of the silver, and 68% of the gold. Significantly, the gold and silver report into the lead concentrate, which will make their recovery easier in the smelter during the next stage of processing.

"In practical terms, if the sample that was processed is exactly representative of the deposit, from each tonne of ore processed in the mill, 12 ounces of silver (386 g), 0.047 ounces of gold (1.5 g), 111 lbs of zinc, and 73 lbs of lead will be recovered. At current metal prices(i), each tonne of ore in ground would be worth US$483 when it leaves the mill.

We have taken another major step towards a decision to put the Hache lens into production, because the recoveries obtained will allow us to improve our economic assessment of the project," observes Andre Proulx, the Company's President.

(i) Current metal prices were taken from the Northern Miner of 12 November 2007: US$817.55/ounce for gold, US$14.96/ounce for silver, US$1.25/lb for zinc, and US$ 1.71/lb for lead.

(i) One tonne corresponding to 2,200 lbs and 1 ounce corresponding to 32.15 g.
