[ICG-TSXV] is aggressively drilling its wholly-owned Lamaque Project in the mining friendly town of Val-d'Or, Quebec. The junior also just announced impres - sive results from a Preliminary Economic Assessment on the project. A total of four rigs are now drilling on the Triangle Zone with assay results from over 10,000 metres pending. The resources defined to date at the Lamaque Project are high-grade, near-surface and next to extensive infrastructure making the project a prime candidate for near term production with low start-up costs. The recently released PEA envisaged a 4.25-year mine life based on mineral resources currently defined in four dis - tinct mineralized zones on the property, the Fortune, Triangle, No. 4 Plug and the Parallel Zone. Taken together, the total indi- cated resources hosted in these zones tallies to 1.5 million tonnes averaging 10.2 g/t gold (499,210 contained ounces). In addition to this, there is another 488,500 tonnes in the inferred category averaging 15.1 g/t gold (236,540 contained ounces). These resources are based on a 5 g/t cut-off grade. Resources at the Triangle Zone were limited to a depth of 620 metres, although drilling has now intersected high-grade mineralization to a depth of 1 km as well as 200 metres south of the current resource limit. All of the mineralized zones on Integra Gold's Lamaque property remain open for expansion laterally and to depth and are structurally and geologically simi - lar to the adjacent Sigma and Lamaque mines. These two historic gold producers pro- duced over 9 million ounces of gold from pipe-like dioritic intrusions and volcanic hosted shear zones with over a half century of respective production, yet seldom had more than three years in reserves, and often less than one. Gold was mined to a vertical depth of 2 km at the Sigma Mine and to a 1.2 km depth at the Lamaque Mine. At the Lamaque Project, gold mineraliza - tion is hosted within a quartz-tourmaline vein system within an east-west trending steeply-dipping shear zone. The veins vary in true width from less than an inch to several feet. Two principal types of quartz veins are documented: sub-vertical and sub-horizontal veins. The veins occupy openings created by extensional fractures during the progressive movement within the shear zone. These fractures were formed preferentially in the more compe - tent dioritic host rocks. The PEA was based on developing an underground mining project in which mineralization would be accessed by way of two separate ramps, or declines, located at the Parallel Zone in the north and the Triangle Zone in the south, approximately 2 km apart. Material would then be trans - ported to an off-site mill for toll processing, eliminating the need for the construc- tion and permitting of a mill and tailings facilities. The pre-production period is estimated to be two years allowing for the construction of surface installations, portal preparation, ramp development and stope preparation. Average annual production after the pre-production stage was estimated to be 460,500 tonnes at a diluted head grade of 8.24 g/t gold for 112,400 gold ounces recovered (average 92.1% recovery). The PEA assumes a toll milling, or contract milling, scenario in which material from the Lamaque Project is processed at a mill FIELD REPORT Integra Gold making the grade in Val-d'Or By Thomas Schuster Gold-mineralized diamond drill core from the Triangle Zone at the Lamaque Project, Quebec.
