Exploration Program

In order for exploration could be carried out efficiently, economically, and the right target, it is necessary to plan based on the principles and basic concepts of exploration before exploration program was implemented.

The principles (concept) basic exploration include:

a. Exploration target

*) Type of mineral (quality specification) and
*) Search geological models of appropriate

b. Modeling exploration

*) Using a regional geological model for the selection of exploration target areas,
*) Determining the local geological model based on field conditions, and describing the geological clues that will be used, and
*) Determination of exploration methods to be implemented in accordance with geological clues obtained.





In addition, the planning of exploration programs must meet the basic rules of economic and design, namely:

a. Effective; the use of tools, individuals, and methods must comply with the state geological deposits sought.

b. Efficient; by using the basic principles of economics, namely the lowest possible cost to obtain the results as much as possible.

c. Cost-beneficial; results obtained can bankable.
Regional geological model can be learned through one concept that is genesa extractive Mendala Metalogenik, which is related to or associated source rocks rocks, geological processes (tectonic, sedimentation), and when the formation of mineral deposits.

Some examples of exploration planning activities:

1. Plan mapping, including;
*) Path planning,
*) Planning support people, which is based on regional geological conditions.

2. Plan geophysical and geochemical survey, include;
*) Path planning,
*) Planning distance / interval data acquisition (sampling / data records), which is based on the general state of ore body models.

3. Planning through the creation trenching sampling test, test sinks, exploration drilling, which includes:
*) Number of paritan test, test sinks, exploration drilling point,
*) Interval / spacing between trenching (location),
*) The depth / length sinks / trenching, the depth of the drill hole,
*) Security (employment and environment),
*) Interval / sampling methods, and
*) Labor force
based on the projection / interpretation of the distribution of sediment in the surface outcrop.

4. Core drilling plans, including:
*) Target ore body to be pierced,
*) Location (impact on drilling accomplished to the point and transfer (moving) equipment),
*) The condition of the location (impact on water resources, security),
*) The depth of each hole,
*) Type device that will be used, including specifications,
*) Number of labor,
*) Transportation equipment, and
*) Number (long) core box.

As far as possible, in each of those plans have included the number / large budget needed. In addition, the basic principle in determining the distance as far as possible meets several other factors, such as:

1. Grid density (interval / distance) between points of observation. The more detailed the work the smaller the grid density (interval / distance) the meeting.

2. Terms of grouping the calculated reserve / deposits. Examples of coal; requirements for classification of measured distance (measured) £ 400 m between points of observation.
Each stage / process of exploration must be able to meet the management strategy of a project / job exploration, among others:

1. Minimize the risk of loss,

2. Allows termination of activities before the increase in the next stage if the assessed results obtained are not profitable

3. Each stage can localize (increase / decrease) the target area so that the probability of a greater benefit, and

4. Budgeting allows exploration costs per each stage to assist in decision making.
