Rockhaven Resources Ltd. Announces Positive Drill Results From Its Plata Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 24, 2009) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce results from two diamond drill holes that were recently completed at its wholly-owned Plata property located in east-central Yukon Territory.

The 2009 diamond drill program tested an area between the P-3 and P-4 veins, where excavator trenching done in fall 2008 had returned encouraging assays that averaged 1060 g/t Ag and 3.57 g/t Au over 1.87 m. The P-3 and P-4 veins are located 300 m apart and host silver-gold-lead-zinc mineralization emplaced within the large scale Plata Thrust Fault. Although they were thought to be part of a single mineralized structure, the area between the two veins had never been drilled due to a lack of access.

The 2009 program included extensive excavator trenching and a total of 346.55 m of diamond drilling that formed a section line perpendicular to the strike of the vein. The first hole, PL-09-52, intersected the vein 120 m downdip of the trenches. It returned 360.0 g/t Ag, 3.29 g/t Au, 1.98% Pb and 4.17% Zn over 1.64 m. The second hole, PL-09-53, intersected the vein 500 m downdip from surface showings and returned 201.49 g/t Ag and 2.07 g/t Au with trace Pb and Zn over 0.82 m. PL-09-53 continued further into the footwall of the thrust fault and also intersected a steeper vein which returned 1790 g/t Ag, 8.28% Pb and 4.97% Zn over a true width of approximately 0.80 m. Significant drill intercepts from both holes are shown on the attached table, while maps and sections illustrating hole locations appear on the Company's website (www.rockhavenresources.com).

Mineralization within the Plata Thrust Fault, termed the Aho Zone, has been traced to over 500 m downdip and 850 m along strike. The 2009 drilling successfully confirmed the continuity of the mineralization between the P-3 and P-4 veins both near surface and at depth.

Bulk tonnage and high angle vein fault targets located elsewhere on the Plata property were also evaluated during the 2009 program by the excavator trenching component of the program. Results are pending from this component of the program.

All analyses referred to in this news release were performed at ALS Chemex in North Vancouver, BC. The samples were collected and handled in ways that ensure security, including chain of custody procedures. One blank and one standard sample were randomly inserted into each batch of samples. Each sample was analyzed for silver, gold and 32 other elements. Silver analyses for high grade samples involved fire assay followed by gravimetric finish (Ag-GRA21). Gold analyses involved fire assay with atomic absorption spectroscopy (Au-AA25). Analysis for a multi-element package that included silver was done by inductively coupled plasma combined with either mass spectroscopy or atomic emission spectroscopy (ME-ICP61a). Samples that exceeded the detection limit for lead were reanalyzed using three-acid digestion and HCl leach followed by inductively coupled plasma coupled with atomic emission spectroscopy or atomic absorption spectroscopy (Pb-OG62).
