| ABSTRACT: | The author has prepared this Technical Report for Hudbay Minerals Inc. (“Hudbay”) with respect to its Rosemont Project (the “Project”), located in Arizona (the “Property”), issued and effective as of March 30, 2017. The purpose of this Report is to present Hudbay’s estimate of the mineral reserves and mineral resources for the Project based on the current mine plan, the current state of metallurgical testing, operating cost and capital cost estimates. This Technical Report provides current estimates of the mineral reserves and mineral resources at the Project and describes the latest resource model, mine plan and the current state of the permitting process, metallurgical testing, operating cost and capital cost estimates. Hudbay prepared a 3D block model of the Rosemont deposit. The Mineral Reserves estimate for the Project are based in a LOM which uses the block model compiled under Section 14, Mineral Resource Estimates, with an economic value calculation per block (NSR in $/ton) and mining, processing, and engineering detail parameters. Mine design and reserves estimation for the Rosemont pit use the NSR block model, which consists of an NSR value calculation for each block in the block model, taking into account grade mill recoveries (Cu, Mo and Ag), contained metal in concentrate, deductions and payable metal values, metal prices, freight costs, smelting and refining charges and royalty charges. These parameters were applied to the block model to form the basis of the reserve estimate. | |
