Puma Exploration: Copper Recovery of 95% at Turgeon

RIMOUSKI, QUEBEC--(Marketwire - April 21, 2010) - Puma Exploration (TSX VENTURE:PUM) has received the results of metallurgical tests carried out on the Turgeon copper-zinc deposit in New Brunswick. A series of tests were conducted on the two types of mineralization found in the Turgeon deposit: copper-rich stockwork zones, and massive sulphide zones carrying copper and zinc mineralization.

The flotation tests produced a copper recovery of 95% and a concentrate with more than 20% Cu from the stockwork zone. The other tests achieved copper recoveries in excess of 80%. In addition, it appears that the mineralization in this zone requires relatively little grinding to obtain a good recovery. Indeed, the optimal grain size is less than 65% minus 200 mesh, and overgrinding may impair the quality of the concentrate and the recovery, as in Test XP-2.

Results of tests carried out on the copper-rich stockwork zone

Test Sample grade Cu (%) Copper content of concentrate (%) Recovery (%)
       
XP-1 3.88 27.2 84.0
XP-2 3.83 17.9 65.4
XP-3 3.90 27.8 91.7
XP-4 3.84 24.8 80.8
XP-5 3.90 23.1 94.7

For the massive copper-zinc sulphide zones the optimal grind for an initial flotation of copper is similar to that for the stockwork zones: about 65% minus 200 mesh. Taking into account the grades of the feed and the grades of the tails, the highest possible recovery for the copper is 90%, and 94% for zinc in the massive sulphide zone. On the other hand, it appears difficult to suppress the zinc during copper flotation, and additional tests will be necessary to obtain a copper concentrate with a minimum content of zinc.

It should be noted that this is a preliminary series of unoptimized tests, and that both the concentrate grade and the recovery are likely to be improved during subsequent testing.

Metallurgical tests

The Company has retained LTM Inc. of Val D'Or to conduct the metallurgical testing of the mineralized zones at the Turgeon copper-zinc deposit. These metallurgical tests are designed to estimate the percentage recovery of copper and zinc from the mineralized zones, so as to assess the economic viability of a project. The Turgeon mill test was performed on the mineralization intersected during the 2009 drilling program on the surface lens. The samples were subdivided into two groups: the first group consists of samples located in the copper-rich stockwork zone, the second group comprises samples from the massive copper-zinc sulphide zone. Two 20-kg samples were collected from each of these two zones. The samples were chosen to reflect the metallogenic zoning of the deposit, in order to estimate the potential metal recoveries from any subsequent production.

About Turgeon

The Turgeon deposit is located only 20 kilometres north of the Nicholas-Denys property, and 5 km south of the deepwater port of Belledune. The property is accessible by road all year round, and is crossed by a power line.

The deposit consists of four lenses of rich zinc-copper mineralization, two of which are exposed on surface. By way of example, drill intersections with 12.4% Zn and 1.8% Cu over 8.7 metres, and 10.7% Zn and 0.7% Cu over 10.1 metres have been encountered in one of the zinc-rich lenses. Spectacular copper intersections are also found, e.g., boreholes E82-77 with 2.5% Cu over 34.1 metres, E82-54 with 2.7% Cu over 36.2 metres, and E82-46 with 7.9% Cu over 7.5 metres. The drilling programs conducted by Puma Exploration in 2008 and 2009 confirm the presence of rich copper-zinc mineralization on the Turgeon deposit.
