Mineral Resources and Reserves
The mineral resources and reserves of the Tocantinzinho deposit were classified using logic consistent with the CIM definitions referred to in National Instrument 43-101.
The mineral resource block model, which serves as the basis of the Mineral Resources and Mineral Reserves in the Study, were developed utilizing 3D lithology models. Table 1 summarizes the Mineral Resources for the Tocantinzinho project as of

The pit optimization was produced using Minesight software which utilizes the industry standard Lerchs Grossman algorithm for analysis. Updated cost and recovery inputs in conjunction with new geotechnical parameters and ramp design from the prefeasibility study were incorporated in the final pit design process.

Mining
The deposit is projected to be mined utilizing owner-operated conventional open pit mining methods. Mining will be completed using 5 meter benches in the saprolite zone and 10 meter benches in the primary zone. Updated pit wall angle designs and Brazilian mining regulations were incorporated into the mine plan.
The mine is estimated to produce sufficient ore to maintain a steady state of feed to the process of 4 million tonnes per annum (tpa) for 10 years, stockpiling a small amount of saprolite ore to be processed in year 11.
Mineral Processing
The process design for the
Tocantinzinho ore is projected to be treated at a rate of 4.0 Mt per annum through a three stage crushing and ball mill comminution circuit. Overall recoveries from the flotation and cyanide leach circuits are expected to be 90% and 75% for primary ore and saprolite ore, respectively. Over the life of the mine an average of 165,000 oz Au per annum will be produced as doré.
Project Economics
Cost estimates were developed to a feasibility level of accuracy. Budget quotations for mobile and plant equipment were obtained from international suppliers. Unit rates for material commodities (earthworks, concrete, and steel) in the Para State area were verified by Brazilian contractor and supplier quotations. Construction and labour costs applicable for the region were built up from first principles for salaries, burdens and overhead. Contingency was applied to each item based on the source and accuracy of the estimate data, resulting in an overall initial contingency of 13%. The Initial Capital Cost Summary is included in Table 3.

Sensitivity of the NPV and IRR to changing capital or operating costs for the base case is illustrated in Table 5 and Table 6 below. While the base case demonstrates a positive return at the Feasibility capital and operating costs, the tables demonstrate further opportunities for improving the economics of the Project by investigating Capital and Operating cost savings. Tables 5 and 6 indicate a 10% decrease in initial capital will result in a 16% increase in NPV and a 15% increase in IRR, while a 10% decrease in Operating cost realizes a significant increase of 38% in NPV and 22% in IRR. Eldorado is confident that the capital and operating costs can be further optimized, improving the value of the project.

Permitting
The permitting process for the
The next step in the permitting process is to obtain the Installation License and the approval of the Economic Exploitation Plan. The preparation of documents for these permits will be completed during the engineering phase of the Project. Granting of the Installation License allows construction on site to commence. The approval of the Installation License and the Economic Exploitation Plan documents is a condition to receiving the Exploitation Concession and the Operation License which will allow operation to commence.
