Cerrado’s principal target of interest is the Serra Alta Deposit.

The intrusive at Serra Alta is a syenogranite, composed predominantly of orthoclase, quartz and albite, with a peraluminous character. It has a moderate alkali content with high potassium, indicating a subalkaline composition. Despite the fact that it possesses certain affinities with A type granites, the samples of the granite studied also have characteristics of highly fractionated I type granites, whose petrographic and geochemical characteristics may be confused with the former. The hypothesis is that such similarities are derived from multi-stage actions involving reworked protoliths submitted to extensive fractionation.

The Serra Alta Deposit is a wide mineralized zone about 300 m wide with approximately 1,500 m of exposed strike length, as demonstrated by the bandeirante and garimpeiro working. The zone is a corridor which contains veined, mineralized shoots generally striking N10°, dipping 60° to 80° W.

MSM and Cerrado geologists were discussing the possible interpretation of three distinct sub-corridors or trends of mineralization within this wider corridor. It is possible that the far western trend is composed largely of colluvium shed from the slope and the artisanal workings there may haveno immediate bedrock source. There are exposed bedrock sources of veining on the eastern side up against the cuesta wall. Extensions of the sheared granite cupola mineralization on ........

The Monte do Carmo Project will be an open pit operation with an average production rateof 2.65 Mtpa of ROM. Surface mining will use a contract mining fleet of hydraulic excavators, frontend loaders and haul trucks, as well as correspondent ancillary equipment.

Final Pit Design
The Mine Design or Pit Design consists of the designing an operational pit that allows a safe and efficient mining operation, based on the optimal pit. The methodology consists of establishing an outline of the toes and crests of the benches, safety berms, work sites and mining site access ramps while adhering to the geometric and geotechnical parameters that were defined. Given the nature of the report, GE21 did not include any access designs from pit to processing plant or waste dump. The following assumptions were adopted for the operational final pit shells for each period of mining:
- Maximize ROM recovery;
- Define access routes to attain shorter average transport distances.

Final Pit Design Parameters:
- Overall Slope - Angle 55°;
- Face Angle - 78°;
- Bench Height - 10 m;
- Berm Width - 5 m;
- Road Ramp Width 15 m;
- Road Ramp Gradient - 10%;
- Curves Radius - 22 m.

Mine Operation
Mine operation will begin on the South portion of the pit. Drilling and blasting of the fresh rock, mostly represented by granites, will be necessary to allow rock handling as materials classified as sedimentary are mainly situat ........
