PUMA EXPLORES THE HIGH GRADE ZONES OF THE ROCKY BROOK AG-AU-PB-ZN PROJECT
Puma Exploration Inc. is actively defining and exploring its mineralized polymetallic lenses along the 15-kilometre Rocky Brook project in New Brunswick, focusing mainly on the highest grade silver and gold portions.
Puma's geologists have compiled and selected the highest potential within each of the main six lenses along this trend showing the highest silver and gold grades in order to evaluate and expand on their size. These mineralized lenses, namely Hache, Shaft, Henry, Henry East, Half Mile and Pine Tree, are spread over a distance of six kilometres and have received very little advanced exploration work to date. Three-dimensional modelling focusing on the high-grade portions of each lens containing at least 300 grams per tonne (g/t) Ag (10 ounces per ton) is currently under way. Surface trenching and stripping programs will be conducted in the vicinity of these zones in order to increase their size and extent.
Hache lens
The Hache lens has received the most focus to date including a total of 87 drill holes, which represents about 50 per cent of the project's drilling (172 drill holes), which was directed to the exploration and definition of the central part of the Hache zone. In 2008, a compliant NI 43-101 resource estimate outlined an indicated mineral resource of 1.11 million ounces of silver within the first 100 metres from surface over an area of only 100 by 50 metres (see news release on Feb. 27, 2008, filed on SEDAR). These resources include some sections of high very high-grade silver content which are currently being modelled in order to showcase the shape and size of the silver enrichment. Follow-up will include with exploration along strike within 25 metres of surface. Since the 2008 resource estimate, 84 additional drill holes were completed from the Hache to the Shaft zones over a strike length of 700 metres.
Geology
The 15 km long by two km wide Rocky Brook corridor is a major mineralized structure which contains the main silver-gold-lead-zinc lenses centred on the Rocky-Brook-Millstream fault which is interpreted to have played a major role in the enrichment of the mineralized lenses. This fault can be followed over a strike length of more than six kilometres. The intersection of this major structure with minor transverse norhtwest-southeast faults is the primary exploration target for the richest silver-gold-lead-zinc deposits as defined by Puma geologists.
The main lenses are composed of massive to disseminated sulphides enclosed within a highly altered rock close to the contact within the Rocky-Brook-Millstream fault. The lenses are subvertical and range in thickness from one to 25 metres.
Fieldwork
The most effective way to explore the area is through trenching. The area is covered by thin overburden, usually less than one metre thick and mineralization outcrops on surface. These features facilitate the access to new data and information that could lead to new discoveries at minimum cost compared with a drilling program. More than 15 kilometres of trenches have been done since 2011 on the Rocky Brook Corridor and have led to the many successful drilling programs as shown in the attached table.

"The Rocky Brook project has always been one of the more exciting assets for Puma. Since 2011, we have constantly conducted fieldwork to increase the knowledge of the mineralized systems. With the current work, we will be able to better evaluate the potential size of the very high-grade silver portion within each lens at a relatively low cost," noted Marcel Robillard, Puma Exploration's president.
About Rocky Brook
Rocky Brook is located in mining-friendly New Brunswick, near sea level in the established Bathurst mining camp which welcomes employment opportunities. The property is located 15 km from the city of Bathurst and 20 km from a deepwater Atlantic port and the nearby Glencore smelter at Belledune. Access is excellent with a commercial airport near Bathurst, a nearby railway and with paved roads running through the property. The project consists of a 15 km long by 1.5 km wide Rocky Brook mineralized corridor adjacent and spatially related with the large four km diameter Beresford copper porphyry intrusion.
The contents of this press release were prepared by Dominique Gagne, a qualified person as defined in NI 43-101. The samples were analyzed at the ALS Chemex laboratory in Val d'Or using the atomic absorption and ICP methods. There is not enough drilling data presently available to determine the shape and true width of the mineralized zone.
We seek Safe Harbor
