Rocmec Mining![]() RUSSIAN KIDThe Russian Kid Gold Mine property includes 11 claims totaling an area equivalent to approximately 84 hectares and is located in the Dasserat Township, some 36 kilometers west of Rouyn-Noranda in the Abitibi region of Quebec. The property is easily accessible via Highway 117. A previous feasibility report prepared by ABBDL – TECSULT, in March 1984 for Metalor Inc., estimated the Russian Kid Gold Mine current in-situ mineral resources at 1,124,532 short tons grading 7.8 g/t gold (equating to 281,133 ounces of gold). This historical resource is not compliant with current standards as outlined in the National Instrument NI 43-101. The company is quoting this historical resource solely as an indication of the potential and to outline the significance of the current acquisition. MRB and associates reviewed the available reports and studies completed by previous owners focusing on the potential of narrow high-grade gold bearing quartz veins. According to Martin Bourgoin, P. Geo. (Qualified person as defined by National Instrument 43-101), president of MRB and associates, numerous quartz veins ranging in width from a few centimetres to 60 centimetres and containing visible gold and chalcopyrite are present on this property. From the expertise acquired by Rocmec on its numerous projects, these veins appear minable by thermal fragmentation process. Much of the historical work on the Russian Kid Gold Mine property was carried out by surface diamond drilling and via a decline that provided access to three underground levels. In all, 15,625 short tons were milled at the Belmoral and Lamaque Mills near Val-d’Or. Prior development included a 100-metre shaft that was later sunk, a 1,000-metre access ramp and 1,300-metres of drift on 3 levels Advantages: InfrastructuresThe property includes a 100m deep two compartment shaft, a 844 metre decline allowing access to three levels (150, 300 and 425 feet). On these levels a total of 1700 metres (drifts and cross-cut drift) were driven. The Russian Kid ore body is well defined by diamond drill holes and sampling including 2 test stopes (McDowell vein). GeologyThe mineralisation is associated to a East-West sheared system, almost parallel, broken by faults which create slight displacements. Some of the transversal faults are important, causing displacements exceeding 30 metres (ex: El Coco fault). The orientation of the mineralised structures vary from N070° to N090° with a dip of 55° to 80° towards the south. The movements created by the transversal faults combined with shearing movements are the reason for the discontinued nature of the mineralization. Fractures and tension veins have also developed in close proximity to the sheared zones. They are strongly silicifyed, very well foliated and are characterized by cataclastic textures with very fine mylonitic grains containing visible or pulverised fragments. The gold veins on the Russian Kid property are quartz carbonated narrow veins included in an intrusive rock with included quartz or granophyric textures. The narrow vein can be confined in a more competent ground. The high grade iron ore is most favourable for gold precipitation. These quartz carbonated narrow veins are normally created in a table and lense shape structure and are present in the central portion of the sheared zone with a fragile-ductile rocky behavior parallel to the host structure and slightly oblique. (Hogson, 1989; Pouilsen et Robert, 1989). Since this type of ore body is low in sulphur, the exploration strategy would be oriented towards geological criteria instead of geophysical criteria. It is important to focus on the sheared zones included in the host rock where high grade iron igneous rock is present. The mapping done by colored mineralised rock is a simple way to localise the more favourable ore zones. MineralisationThe mineralisation is composed of 2 to 10% of fine pyrite dissiminated in sheared zones and breaches breaking the diorite. Numerous quartz veins ranging in thickness from a few centimeters to close to 60 centimeters are frequently located in these zones. The veins also contain pyrite, chalcopyrite and visible gold. Silver grades are usually four to five times lower than gold grades. Metallurgical test and ore treatmentIn 1983, two 45 kg samples from the 425m level of the Beaudoin vein and from the 300m level of the McDowell West vein underwent treatment testing at the Center for Mineral Research (CMR) of the government of Quebec. Gold grades from the Beaudoin and McDowell West veins were 12.8 and 30.3 gr/t Au respectively. Gold recuperation rates with cyanide testing following a recrushing period of 25 minutes of flotation concentrate from the Beaudoin vein attained 95%. However, gold recuperation rates without resorting to recrushing of concentrate from the McDowell West vein were 91-92%. Table outlining resources
NOTEEven though the resource categories used by ABBDL-Tecsult (page 60 ABBDL-Tecsult report) are not in accordance with the National Instrument 43-101, they are stated in this document for the sole purpose to allow the reader to appreciate the significance of each mineralised zone in accordance with the global tonnage and grades of the deposit. The authors of the report did not include the 200,000 tonnes classified as “geological” resources attributed to the Talus vein because additional exploration work is required. Tonnages were calculated on vertical sections at 100 foot spacing. The area of influence of each section was 50 feet on either side. No intersections with values lower than 0.10 oz/ton Au were included in the calculation. Separate tonnage calculations were performed on each mineralized vein. All gold values over 1 oz/ton Au were cut to 1 oz/ton Au. Analysis from underground channel sampling was given greater weight in the tonnage calculations than diamond drill holes. Tests to determine gold recovery have shown that recoveries of between 94% and 96% are achievable. Drilling has indicated that the property has significant potential below the underground workings. Examples of the deeper, widely spaced drill holes are listed below. For example: NB-04 0.61 oz/ton over 4 feet 675-foot level 67-6 0.13 oz/ton over 4.7 feet and 0.13 oz/ton over 5.6 feet 750 foot level NB-05 0.58 oz/ton over 4 feet 775-foot level NB-02 0.62 oz/ton over 4 feet and 0.16 oz/ton over 5.1 feet 850-foot level NB-19 0.29 oz/ton over 3.5 1,000-foot level A vertical drill hole to the 1,564 foot level intersected gold values up to 0.58 oz/ton over short widths indicating that the potential exists to increase tonnage both to depth and along strike well below the drill defined resource. Subsequent to the feasibility study of 1984, 13,400 feet of diamond drilling was undertaken in order to further test the gold bearing vein system. |
