The Fortune Zone (formerly the “Forestel Zone”) is located approximately 800 meters east of the Parallel Deposit, and is the easternmost gold bearing zone of the North Cluster.
Like the Parallel Deposit, the Fortune Zone was originally modelled as a bulk open pit target; this interpretation was changed for the latest resource estimate leading to a higher grade underground resource. The Fortune Zone now appear to have limited down-dip and lateral extent, no additional work is recommended on that zone at the moment. The veins in the Fortune zone are shallowly dipping and are present between east-west striking sub-vertical shears in volcanic rocks.
No. 3 Mine
The Veins at the No. 3 Mine are located south and north of the No. 3 historic shaft, and 400 meters southeast of the Parallel Deposit. The veins are continuous over an E-W strike length of about 300 meters, extends from the 150 to 400 meters levels, and dips to the south at 80°. The veins are composed primarily of quartz and carbonate with lesser amounts of tourmaline. Pyrite is the predominant sulphide mineral but it is rarely present in quantities greater than 3 to 5%. Four veins were identified by Teck drilling in the No. 3 Mine area (Blecha, 1986). These veins were named the No. 1, 2, 3 and 4 veins.
The veins vary in width from 0.5 to 2 meters; all veins are located within a dioritic intrusive. Potential for additional mineralization exists at depth where the veins were intersected in more recent drill holes. None of these, however, encountered significant high grade gold values. The auriferous zone most probably follows a plunge towards the east as is often observed for gold concentrations in ore shoots of the camp in general.
No. 6 Vein
The No.6 Vein host rocks mainly consist of chloritized tuff and diorite. The diorite is silicified and locally sericitized and/or carbonatized. Shearing affects all rocks but very locally there are fractures and/or brecciation. Several mineralized veins are present; their length varies between 0.5 cm and 90 cm with trace to 7% of pyrite, locally 10%, and trace-1% of pyrrhotite and chalcopyrite locally. Few veins bear visible gold. They are made up of quartz-carbonate-tourmaline-chlorite and/or sericite/feldspar.
The Sixteen Zone was named from the T-16 magnetic anomaly defined in a geophysical compilation from 1986. It is located in the western part of the Lamaque South property, just north of the Val-d’Or southern south by-pass road. This zone is oriented east-west and has a strike length of 250 meters. The zone is a system of quartz/tourmaline/pyrite veins, and associated alteration, within a steeply north-dipping, east-northeast trending, feldspar porphyry dioritic dyke.
Drilling in 2010 was conducted to validate previous historic results and if possible extend the mineralized vein array. Additional definition drilling in 2011 was completed with the intention to extend the zone laterally with mixed success.
The No. 5 Plug
The No. 5 Plug is located in the northwest part of the tailings, approximately 500 m northeast of the Parallel Vein Zone and 790 m north of the No. 3 mine shaft, to which it is connected by a drift on the 700’ level. The No. 5 Plug was mined, yielding 5,572 short tons grading 0.11 oz/t Au (5,054 t at 3.8 g/t Au) from workings above the 3,200’ level. It is located 1.5 km from the shaft of the Main mine. The No. 5 Plug is composed of fine- to medium-grained diorite, 200 to 250 m in diameter, with potential expansion at depth. It is mixed with a granodioritic intrusion. The two intrusive units have similar competency and therefore should be equally good hosts for gold-bearing quartz veins; however, mining was restricted to the dioritic portion of the intrusive.
The mineral resources presented herein are not mineral reserves and thus do not have demonstrable economic viability.
