Rocmec 1 (Russian Kid)
ROCMEC 1 GOLD PROPERTY
Property Description and Location
Figure 1: Location of the Rocmec1 property
The Rocmec 1 project is located in the Dasserat Township, Province of Québec on the shores of the Labyrinthe Lake. It is approximately 35 kilometres west of the town of Rouyn-Noranda and is easily accessible from Route 117 and the frontier gravel road separating Quebec and Ontario and a secondary gravel road to the site (click for map, geology and mineralisation). The property was acquired in October 2005, dewatering and rehabilitation of the mine commenced in January 2006. To date, Nippon Dragon has invested approximately $33,000,000 in rehabilitating the property, surface and underground infrastructure, diamond drilling, equipment, drifting and the acquisition of a 75 tpd treatment plant, designed for underground installation. The property includes a 100m deep two compartment shaft, an 844 metre decline allowing access to five levels (50, 70, 90,110 and 130 metres). On these levels a total of 1700 metres (drifts and cross-cut drift) were driven. The Rocmec 1 ore body is well defined by diamond drill holes.
Structures and results: Generally speaking most of the zones look alike in terms of structure and mineralisation; some differentiate lightly by the content in quartz, pyrite, sericite and chlorite but for now they are believed to be all related to the same geological even. Along the zones in underground openings pinch and swell was observed along the main shear plane, the zone is always there with variation of the thickness and grades. Descriptions of the best known structures are listed below;

This mineralized zone recognized by diamond drill holes is near surface to the west of existing shaft, no special name was given, only in accordance to the fact it sits in front of the McDowell i.e. on the hanging wall. Actual known extent of the zone ranges from 5950Me and 6080mE near surface to 110m at depth. Grades range from trace to 67.87 g/t. and widths vary from 0.15 metres to 1.53 metres. The best intersection encountered is 67.87 g/t over 1.44 metres.
The McDowell vein is the longest gold bearing structure on the property. This main dislocated structure represent the Western McDowell vein, McDowell, the West Claude, the Russian Kid and the Beaudoin vein form one continuous orebody, The structures were followed in the underground development or intercepted by diamond drill holes for 1660 meters East West with an average width close to one (1) meter. The pyrite associated with the vein is present in millimetre-length veinlets within the mass of quartz and preferably in contact of the vein with the wall-rock. The Hanging wall and the footwall both contain coarse pyrite. Lower vein wall (foot wall) is characterized with fine pyrite and is disseminated over more than three meters. It is carrying gold bearing mineralization until a vertical depth of 400 meters. This vein was developed and followed with the underground levels 150, 300 and 425(ft) now level 45, 90 and 130 meters. Grades range from 0.03 g/t to 120.00 g/t and widths vary from 0.07 metres to 5.00 metres. The best intersection encountered is 74.65 g/t over 2.34 metres.
The Talus vein is probably a secondary sub parallel branch structure to the McDowell vein whose junction point is located close to the section 6445mE. The Talus vein extends to the west of this junction point and is followed and identified up to the 6000mE coordinate. Some sampling of the vein was done in the drift at the 90m level. The actual known extension at depth is 400m. Grades range from 0.03 g/t to 61.58 g/t and widths vary from 0.05 metres to 3.04 metres. The best intersection encountered is 37.02 g/t over 1.22 metres.
Located near the mine shaft, the vein is encountered at level 45 meters. Gold bearing mineralization appears in a broad brecciated zone consisting of alternating silicified, pyritized and sericitized diorite bands, and thin milky quartz bands. The distribution of the gold contents is erratic although gold values increase at a depth. The results of sampling of drift made by North Bordulac Mines show that there would be more than one gold bearing structure besides the shaft as North and South satellite veins to the shaft veins within that sector, these are not taken into account in the resource estimation at the moment. Grades range from 0.01 g/t to 28.01g/t and widths vary from 0.12 metres to 2.41 metres. The best intersection encountered is 18.15g/t over 1.53 metres.
During one site visit in November 2006, core from the new Nippon Dragon diamond drill hole RS- 06-01 was reviewed and sampling instructions were given, the mineralized zone was spectacular with presence of visible gold associated with quartz carbonate vein. The zone is located at 165m on the footwall of the McDowell zone. The zone is very impressive and differs significantly by the amount of quartz and the mineralized core width. Visible gold was observed and special sampling procedures were taken to obtain a representative assay value. Grades range from 0.01g/t to 29.94 g/t and widths vary from 0.43 metres to 2.74 metres. The best intersection encountered is 20.06 g/t over 1.45 metres (click to view core samples).
Pictured right present the aspect of the visible gold and the Boucher zone.
The Boucher 2 zone is similar to the Boucher, but it is located 25 m behind to the north on the foot wall of the Boucher, locating it almost 190m from the McDowell, no other diamond drill holes have reached such a distance from the McDowell on the north side. It also indicates that mineralization is not limited to the actually known corridor but extent to the north of the previously known sectors. Grades range from 0.01g/t to 29.76 g/t and widths vary from 0.16 metres to 3.77 metres. The best intersection encountered is 27.91 g/t over 1.77 metres.
Diamond drill campaigns: Nippon Dragon conducted several diamond drill campaigns on the Rocmec 1 property over the past years, two of which by contractors, the others by Nippon Dragon employees. All of the diamond drill campaigns were designed and carried out following the reasoning of “drill for structure and drift for grade”. A NI43-101 compliant report was prepared Système Géostat International of Blainville (Quebec) and made public in May 2010. The results delineated measured and indicated resources of the Boucher and Boucher 2 structures totalling 22,700 ounces respectively, the Boucher Structure of 58 700 tonnes at 5.46 g/t Au totalling 10,300 ounces and the Boucher 2 structure of 31,500 tonnes at 12.20g/t Au totalling 12,400 ounces with a cut-off grade of 3 g/t This is the first time that Nippon Dragon obtains this type of resource category for the structure that was discovered in 2006. The Boucher vein has now been indentified over a distance of 450 meters in length, at depths of 450 meters and remains open in all directions.
In summary, by viewing the classification table of global resources below, prepared with a cut-off grade of 3 g/t, an industry standard. The resources measured/indicated now total 570,300 tons at 6.52 g/t or 119,500 ounces vs. 477,400 tons to 5.59 g/t or 85,900 ounces as announced in the press release dated March 3rd 2010.
