1° Exploration Geologists Diamond creo drilling

Reverse Circulation Drilling

Geological Mapping

• The diamond drilling is based on erosion or wear of geological formations or rock friction, the immediate effect of the rotation and boost pressure it is subjected to the bit or diamond crown against the rock • In reverse circulation, the drilling fluid and cuttings to the surface is the interior of the linkage to a sludge pond. In this tank, the sludge is recovered for re-drilling through the annular space between the rods and drilling.

• Basic tool in which information is collected. The planning, town and country planning, building, valuing natural resources, particularly groundwater, prevention of geological hazards, geological map need fundamental basis.

2° Mine Planning Engineers The process of mining planning must deal with the uncertainty of many of the variables associated with mining such as the occurrence of events of interference and the real capabilities of the mining productive infrastructure. Pit Optimisation RAMP WIDTHS

Is the division of volume 3 - D in blocks of a size appropriate to give a reasonable assessment of the mineral content.

main ramps wide 3.2 - 6.0 m height 3.0 - 4.0 m auxiliary ramps width 2.5 - 3.5 m height 2.5 - 3.0 m MINING COSTS The "costs of operations mining", is translated into a concept of "Spending money"; that is, measure the mining-metallurgical operations, in of money.

WALL ANGLES

It represents the inclination which is the wall of the Bank. This angle is measured from the foot of the Bank at its own crest. PROCESS COSTS refers to expenses that operation of the mineral generate either machinery, production, treatment.

BENCH HEIGHTS It means the difference in elevation between two banks.

GOLD PRICE The price of gold as a reason for the best long term investment. $1315.80 oz

COSTS

istration costs to service payroll operations include mine and plant management, equipment costs, field operations and processes, human resource management, licensing, maintenance of access roads to camps, food, systems (software and hardware) and civil security among major to be considered.

Pit designs Its application to define the limit of the Tagus, are represented by such important factors such as the geometric shape of the orebody, the distribution of ore within the body, the topography of the area, the maximum final batter stop according to the consistency of the rock.

3° Mine Production Engineers  Long Term Scheduling: These models Long Term (MLP) are used for the prediction of cash flows, such as Feasibility Studies, and include a mining sequence, estimates of laws and tons to be recovered by significant volumes but variable.  Short Term Scheduling: A Short-Term Model is built to provide a basis for planning weekly daily and more commonly, that is, includes Model Control Laws, constructed to define the selection daily ore / waste.

Drilling

Quality control

Grade Control Plan & Drilling

Is break a sterile material layer in order to perform this hole then being filled with explosives and fracturing the crust.

Design Ore Blocks

In deg mineral blocks can be observed with a positive sum columns (which makes us understand the value by the amount of harvested blocks and not have any interest) and then a statistical summary of the variables thrown pit by the program, these data taken to generate the financial assessment of the project and have a longer term planning feasible

5° Drill and Blast Engineer Blast Hole Drilling Plan

Blast Hole Drilling

Charging of Blast Holes

1. Check

Tools are formed by a mechanism of producing the effects of percussion or rotation of the auger is provided with a drill bit at its leading end. The punch is determined according to: type and size of the artwork, terrain, depth and scope of the holes, the rock or stone you want to occur.

6° Mining Contractor Fire Blast

Haul Material

Load Trucks The loading is to load the site mineralized material to lead to potential destinations, either the crushing, ore Stock or sterile dump.

Removal of ore materials are sterile and electric shovels and loaders caterpillar, the materials are loaded onto trucks- dump to be taken to the block.

Gold ore As the ore is located closer to the surface and this is extracted wide stands are built into the walls of the mine to allow access to the ore which is deeper. These steps provide paths for the vehicles of the mine.

Crushed Ore To Mill

waste Feed Gold Ore To Crusher The ore is discharged to a machine for primary crushing, the crushed material is stored in piles or stacks on the floor before being sent to the plant where materials are separated and concentrated sterile materials of interest
