| ABSTRACT: | This report has been prepared for the Bullfrog Gold Corp. (Bullfrog, or the Company) for the Bullfrog Gold Project (Project) in Nevada. Gold was produced from the Bullfrog project by various companies, with Barrick Bullfrog Inc. being the most recent. The mine was exploited through open pit and underground methods and ore was processed in a conventional cyanidation mill. This report has been prepared for the purposes of producing an independent estimation of mineral resources that are still available at the site. This included a review of the drilling data for the project to date, including historical drilling. Resources have been estimated for the Bullfrog deposit using a block model to fit the deposit strike for each of the areas. Two separate block models were created, one for the Bullfrog Pit (BF) area, and one of the Montgomery-Shoshone (M-S) area. Sub-blocking was used to help define the vein system. Two wireframe domains were built for the Bullfrog deposit, one for the high grade and one for the low grade gold. Vein solids were created for Polaris and Montgomery veins in the M-S pit area. Au and Ag grades were estimated using Ordinary Kriging on blocks independently within and also outside of wireframe constrained domains. Reporting of estimated blocks has been constrained by a base case pit optimization using input parameters deemed reasonable. Although the mineral resources are pit constrained using reasonable cost assumptions, detailed costing and economic evaluations have not been performed. The pit optimizations only consider ounces on lands controlled by Bullfrog Gold, but the pit has been allowed to extend onto non controlled land for planning purposes. The pit optimizations include resources that have not demonstrated economic value and include inferred resources that are too speculative for the definition of reserves. | |
