| ABSTRACT: | The metallurgical performance is a function of gold head grade, the deportment of which is understood per the reserve model. Gold head grade providing a means to estimate recovery per the algorithm presented herein. The test work also suggests a telluride association as would be expected given the mineralogy of the ore and this may improve the accuracy of the recovery estimates. There is no tellurium model available for the reserve at this time. Executive projects for the filtered tailings pile and waste dumps were developed for the two first years of production. Additional studies and designs at a PFS level were then completed to accommodate the remaining materials until the end of the life of the mine. Future engineering iterations should increase the level of accuracy of these studies as required by the mine. Twenty-one drill holes were completed within the limits of the planned tailings pile to assess the geotechnical conditions. However, no samples were collected for laboratory analysis. The geotechnical parameters of the foundation need to be better understood through shear stress tests under dry and wet conditions covering all concerned lithologies. | |
