1° Exploration Geologists

• Those responsible are the geologists to find new deposits.• use techniques such as remote sensing, photo geology, cartography, geology, petrology,

geophysics

Diamond creo drilling

• 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

Reverse Circulation

Drilling

• 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.

Geologic

al Mapping

• 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

Pit Optimisation

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.

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

RAMP WIDTHS

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

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.

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

MINING COSTS The "costs of operations

mining", is translated into a concept of "Spending

money"; that is, measure the mining-metallurgical

operations, in terms of money.

PROCESS COSTS refers to expenses that

operation of the mineral generate either machinery,

production, treatment.

ADMIN COSTS Administration 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.

• Ramp Widths • Wall Angles • Bench Heights• Production Targets: is the number of units expected to

produce ore mine. is about finding new points of perforation with mineral profitable

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.

Design Ore Blocks

In designing 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

Blast Hole Drilling Plan

Blast Hole Drilling

Charging of Blast Holes

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 Load Trucks

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

Haul Material

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 waste

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.

Feed Gold Ore To Crusher

Crushed Ore To Mill

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
