Recent (2010) drilling (2,816.36 metres distributed over 14 DDHS) was conducted in order to validate previous results and extend the mineralized vein clusters. Some definition drilling (2011) is planned with the intention to add ounces to the resource calculation.
The Sixteen Zone was named for the T-16 magnetic anomaly defined in a geophysical compilation from 1986. It is located in the western part of the Property, just north of the southern By-Pass road between lines 212 W and 180 W.
Within the property the mineralized zones are defined as mesothermal, structurally controlled deposits, which are typical of the Abitibi Greenstone Belt and abundant in other Archean greenstone belts around the world. The gold bearing quartz-tourmaline veins are young in geologic age and cut all rock-types including irregular intrusive (diorite) bodies, which are affected by regional deformation and greenschist grade metamorphism. In the Sixteen zone, most of the gold intersection was in a porphyritic Diorite and porphyritic granodiorite with 1 to 5% of pyrite in quartz tourmaline sericite carbonate veins.
The Villemaque or Mylamaque property block, equivalent to CM 375, which comprises a large part of the Teck-Golden Pond JV property was purchased by Teck and Mymar Mining and Reduction Limited (later changed to Dynamar Energy Limited) from Villemaque Gold Mines in 1977 for indebtedness. In July 1991 Dynamar forfeited all rights to the property to Teck as a result of non-payment of its share costs.
In 2003 Kalahari (now Integra)aquired the Lamaque Property from Teck Corporation. There are three known mine shafts on the Property, the No 2 shaft, the No 3 shaft and the Villemaque (Mylamaque) shaft.
The Villemaque property situated in the southern part of the property. Blecha (july 1985 and Scammell ans Frostad (november 1988) report that 45,000 feet (13,716 neters) of drilling in 75 surface drillholes were completed in the property between 1937 and 1948. These holes (P, Q, R series) are shown on Teck's geological compilation maps but not appear to be in the property database provide by Teck Cominco. In 1948, a vertical 3-compartment shaft (the Mylamaque Shaft) was sunk to a depth of 243 feet (74.06 meters) and 757 feet (230.73 meters) of lateral development were undertaken on two levels. A bulk sample consisting of 702 tons was extracted in 1950.
In 1962 magnetometer survey was conducted by Geophysical Engineering and Surveys Limited, in 1983 and 1984 a vertical gradiometer survey and seven drillholes totalling 4,073 feet (1,421.45 meters) testing magnetic anomalies was done. Blecha notes that the only occurence of gold mineralization indicated on the Villemaque property block other than that developed in Mylamaque shaft was indicated in hole R-12, wich encountered 0.044 oz Au/t over 2.5 feet (0.76 meters). This intersection was located close to a contact with a porphyritic intrusion.
No. 6 Vein
The Vein No. 6 target area is located approximately 600 m west of the historic Lamaque Mine Main Plug, which produced over 3.6 million ounces of gold and was part of the Sigma/Lamaque complex which in total produced over 9 million ounces. It has an estimated east-west strike length of 250 m, extending to a vertical depth of up to 350 m. Gold mineralization is contained in two predominant vein types: veins interpreted to be tension veins dip at about 50° while steeper dipping veins at 75° are interpreted to be hosted in sub-vertical shears. The sometime stacked veins are hosted by a series of massive andesite/dacite and crystal/lapilli tuffs with several feldspar porphyry dykes, a geological setting similar to some of the gold bearing zones known to exist at the close-by Sigma Mine. True thicknesses of individual veins usually vary from 0.1 to 1.5 m. Veins are primarily composed of quartz-carbonate with lesser amounts of tourmaline and chlorite. Pyrite is the predominant sulphide but it is rarely present in quantities greater than 5%.
As part of its 30,000 m 2012 drill program, a total of 3,980 m in 12 holes were completed on this target in the spring. The main objective of the program was to follow-up, laterally and at depth, on intercepts reported in 2011 which included 8.32 g/t Au over 2 m and 5.51 g/t Au over 5 m

Other Mineralized Zones
Several zones of mineralization (No. 35 Vein, North and South Shears) located north of, and/or within the No. 5 Plug were drilled by the Teck-Tundra JV from 1986 to 1988 (see Figure 6). Numerous other zones of mineralization have been intersected on the Property. Many of these latter zones were defined by intersections described in pre-1988 drill holes. In order to use this older data a review of the older drill hole logs and a creation of a digital database is required so that the intersections can be plotted on plan and section. These zones, and recently discovered new zones such as the Sigma Zone will also be validated and verified with additional drilling and eventually evaluated with definition drilling permitting resource calculations to be calculated.
