TerraX Minerals Inc. Nov. 13 said surface sampling has significantly expanded Duck Lake zone at Eastbelt, one of three large land packages that make up the company's Yellowknife City Gold project immediately adjacent to the capital of Northwest Territories.

In July, TerraX reported that surface sampling had identified flat dipping quartz veins ranging up to 1 meter thick exposed over a strike length of at least 500 meters at Duck Lake.

The highest grade samples collected from Duck Lake during this initial prospecting were 20.3 grams per metric ton and 19.35 g/t gold.

Further prospecting and mapping programs have extended the gold mineralization associated with the Duck Lake structures 2,000 meters south of the Duck Lake discovery into the main granite intrusive areas and 3,000 meters east into a narrow neck of granite intrusion.

TerraX said flat stacked veins in close proximity with granite intrusions identified at Duck Lake are similar to the Lamaque style deposits in Val d'Or, Quebec.

TerraX geologists collected 159 outcrop grab samples at Duck Lake - 31 quartz vein samples (flat veins) hosted in granites with grades up to 1.21 g/t gold; 34 composite quartz vein and granite samples with grades up to 6.19 g/t gold; 26 granite samples proximal to quartz veins with grades up to 1.09 g/t gold; and 68 flat veins within metamorphic sediments with grades up to 35.4 g/t gold.

TerraX plans to analyze the detailed mapping that was carried out during the prospecting at Duck Lake, with the goal of identifying intrusive centers and the more favorable intrusive rock types for gold mineralization.

This work will be assisted by airborne magnetic, radiometric and electromagnetic surveys which were carried out this summer, along with lake sediment and biogeochemical surveys completed this fall.
