International Minerals, a silver and gold producer, has declared additional drilling results from its Goldfield gold project located in southern Nevada.
The company expects to conclude a feasibility study in the Q3 of 2012. In addition, the firm has announced encouraging results from the metallurgical tests done on mineralized material.
Three major mineralized areas, which comprise Gemfield, Goldfield Main and McMahon Ridgem are included in the Goldfield gold project. The property also includes a number of reconnaissance targets that are presently being studied.
The latest assay results comprise core drill and reverse circulation holes designed to classify, expand and improve the present mineral resources at the Gemfield deposit. This is part of a feasibility study, which will be concluded in the Q3 of 2012. The Gemfield deposit signifies the largest percentage of the mineral resources at the Goldfield gold project.
So far, the company has announced the assay results for 43 core drill holes and 244 reverse circulation holes, adding up to 56,842 m at the Goldfield gold project.
In the Gemfield gold project, drill hole Gemc006 intercepted 3.1 g/t at24.4 m; Gemc 025 intercepted 3.1 g/t at 12.2 m; Gemc 026 intercepted 2.1 g/t at 38.1 m; Gemc 029 intercepted 1.2 g/t at 50.3 m; Gemc 030 intercepted 2.6 g/t at 67.1 m; and reverse circulation hole Gem 434 intercepted 2.7 g/t at 25.9 m; Gem 436 intercepted 1.7 g/t at 44.2 m; and Gem 443 intercepted 6.8 g/t at 39.6 m.
The extension drilling campaign targeted the Gemfield deposit’s southeast section and the dipping extension to the west of the Gemfield deposit. The objective of the definition drilling campaign is to improve the regions of inferred resources to the indicated or measured category and to delineate the high-grade zones inside the deposit. The definition drilling will aid in improving the resource estimation quality.
The company has received the final results for column leach tests on composites produced from the McMahon Ridge and Gemfield deposits. These results revealed that the composites on the Gemfield deposit gave metallurgical gold recoveries from 85% to 90%, while the composites on the McMahon Ridge deposit returned metallurgical gold recoveries from 36% to 79%.
The company has not defined the overall metallurgical recovery for the feasibility study. However, it is believed to range from 60% to 70% for the McMahon Ridge deposit and 80% to 90% for the Gemfield deposit.
