Rockhaven Resources Ltd. Begins 2008 Drilling Programs
June 05, 2008 — Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce its exploration plans for summer 2008.
Plata Property
Camp construction is now underway at Rockhaven’s 100% owned Plata silver-gold property and diamond drilling is expected to start by June 8. The Plata property is a former small-scale silver-lead-gold producer that is favourably located within the Tintina Gold Belt in eastern Yukon. Rockhaven’s 2008 exploration goal at the Plata property is to establish a National Instrument 43-101 compliant resource.
A 275 line km, magnetic and VTEM geophysical survey done in 2007 defined anomalies down dip and along strike of known targets and discovered several new targets, many of which appear to be blind to surface. The locations and orientations of several of the VTEM conductors coincide with some of the more than 20 known veins. Two diamond drills, a bulldozer and a excavator are currently being readied for mobilization to the property. Approximately 50 diamond drill holes totalling about 5600 m are planned during phase one of exploration at the property. This drilling will systematically explore showings representing three types of mineralization that have been identified on the Plata property (see Rockhaven’s corporate presentation on its website to view a sample VTEM section and 2008 proposed drilling locations).
Plata Mineralization Types
1) High grade, silver-rich siderite-sulphide lenses are hosted in vein faults. These lenses are typically a few metres to 100 m long and a few centimetres to 10 m wide. They are mineralized with heavily disseminated to massive galena, tetrahedrite and minor sphalerite in a gangue of siderite with lesser quartz and minor barite and calcite. The lenses commonly grade between 1,714 and 10,285 g/t (50 and 300 opt) silver with 30 to 70% lead and 5 to 20% zinc. Most of the veins on the property are of this type and all of the historical production has come from them.
2) High- to medium-grade silver and gold are found in sulphide-quartz-clay veins within the plane of a thrust fault. The P-3 and P-4 veins are of this type and are expected to receive the majority of drilling in 2008. These veins show good consistency of widths and grades, both laterally and down dip. Previous work suggests that they average about 400 g/t silver and 3.3 g/t gold. They are mineralized with arsenopyrite, pyrite, galena, boulangerite, tetrahedrite and sphalerite in quartz- and clay-dominated gangue. These veins are located about 450 m apart and may be part of one continuous vein structure.
3) Medium- to low-grade, silver- and gold- bearing quartz-sericite stockworks and veins are controlled by shallowly dipping, clay-altered shear zones. These zones have potential to host bulk tonnage mineralization and will receive some trenching and drilling in 2008.
Other Projects
Rockhaven recently announced an offering to raise an additional $650,000. These additional funds will be used to advance Rockhaven’s 100% owned Zap and Groundhog silver properties.
The Zap property is located in central Yukon and hosts silver-lead-zinc mineralization with high grade vein and bulk tonnage potential. Previous operators carried out extensive exploration activities, including diamond drilling, between 1977-1979. Although this work defined one of the largest and strongest silver-in-soil anomalies in Yukon, the drilling returned generally disappointing results. Geological mapping done after the drilling showed that none of the drill holes intersected the likely sources of the anomalous soil because the holes were lost before reaching target depth or were drilled sub-parallel to the mineralized structures. Rockhaven will drill approximately three to four holes totalling about 500 m. Drilling is expected to begin in early July.
The Groundhog property is road accessible and is located in south-central Yukon. It hosts a large area of silver-lead-zinc vein and manto-type mineralization that was discovered in 1956. Since then, sporadic exploration has outlined numerous showings, largely by prospecting and bulldozer trenching. Limited diamond drilling and small scale surface mining has been conducted at a few of these showings. A property-wide VTEM survey, soil sampling, mapping and prospecting are planned for summer 2008. This may be followed by excavator trenching in fall. The objective is to ready this property for drilling in 2009.
Tri Origin Exploration Ltd. has an option to acquire a 70% interest in Rockhaven’s North Abitibi property located 150 kilometres north of Kirkland Lake, Ont., in the Abitibi greenstone belt. Tri Origin has announced an exploration program that will consist of prospecting, geological, geochemical, geophysical surveying and diamond drilling. Drilling is anticipated to commence in late June and will test high-priority targets identified by geophysical and geochemical surveys that are currently underway.
