Percussive Cum Rotary

Water is injected through hollow steel drill rods to cool the bit head return water flushes out the crushed material

Percussive Cum Rotary

Examples: Jackhammer and Wager drills

Percussive Cum Drill

Extensively used for mineral exploration, dam sites + other foundation test works, mine development face, drainage of mine workings, mine vent., oil structures investigation and oil gas wells

Diamond drilling

(bentonite, barite) prevents damage of drilling tools, serves as lubricant

Drilling mud

attached byw the lower end of the drill rods and the reamer shell. It jolds the core inside while drilling and brought to the surface

Core barrel

Withdrawing the core and inner tube assembly (core barrel) from the hole without pulling out the hollow drill rods by seperate hoisting unit fixed at a different pulley

wire line drilling

Work on the pronciple of reverse circulation

Continuous Core Drilling

Refers to circulating air down to the but head outside the drill rods and returning it up through inside the bit, core barrel and drill rods

Reverse Circulation

commonly used for open pit excavtion of iron ore , bauxite , lime stone, rock phosphate and coal seams

RC Drilling

usually in scanty outcrops ____ are collected on a relatively closely spaced rectangular/square grid pattern at specified intervals

Soil sampling/ Talus Debris (Float)

for analyzing whther it would be useful in the detection of concealed mineralization with a thin cover

Float samples

Commonly during initial stage of surfaces geochemical exploration

Pitting/ Pit samples

are often cut across the ore body after the probable configuration of mineralizayion is outlined either by pitting or by rock / soil sampling

Trenching/ Trench Sampling

collection of representatives broken material generated by pitting, trenching, mine production etc.

Stack/ Dump Sampling

Few handheld spade or mechanized shovels full of mineralized fragments and fines collected from the mine face or stope draw points

Much Sampling

Usually less consilidated materials (weathering) but stratified

Alluvial Placer

for unirformly distributed mineralization (veins,stringers, disseminations)

Channel Sampling

For hard dense irregularly distributed/disseminated mineralization

Chip Sampling

for flat thpe/near surface deposits( bauxite, laterite) perpendicular bisectors are drawb btw every drill hole; areas are planimgered/calculated

Polygonal Method

for flat type,low-dipping disseminated deposits

Contours/ Isograde Method

constructed by interpolation btw loints of known values that assume a gradual uninterrupted change from one point to another

Isolines

Thickness of contours

Isopachs

Estimates a block of ground that is bounded btw regularly spaced sections

Cross-section Method

Regular grid of suitable size and an orientation is adjusted on a set of drill holes

Randon stratified Grid Mthod

for mapping if surfaces from limited sample data and the estimation of values at unsamples locations

Geostatistics

Recognizes that the samples in a mineral deposit are spatially correlated with one another, and that the samples at closer spacing are probably not independent and should be likely close in values

Geostatistics

Used to express the degree of rationship btw the points on surface Dependent on distance btw points

Semivariance

an optimal spatial interpolation technique that uses the semivariogram in calculating estimates of the surface at grid nodes

Kriging

Estimating unsampled point values or block averages from a finite set of observed values sampled either on a regular or an irregular sampling pattern

Kriging

adopted by ghe PSEm, GSP and SMEP; PSE as part pf their listing and disclosure rules and MGB, as part of their regulatory and repotorial requirements

PMRC (Philippine Mineral Reporting Code)

is to contribute to earning and maintaining that trust by promoting high standards if reporting of mineral deposit estimates (Mineral resources and mineral Reserves) and of exploration prgress (exploration results)
